Coating classification: silicone coating

Core tip: Introduction: Organosilicon coating is a kind of polymer which is composed of silicon atom and oxygen atom alternately, and different organic groups are connected with silicon atom It is a kind of coating which takes organosilicon polymer or its modified polymer as the main film-forming material It has excellent heat resistance, cold resistance, corona resistance, radiation resistance, hydrophobicity, stain resistance, chemical corrosion resistance, electrical insulation and elasticity In recent years, it has developed rapidly in product modification and application If the silicone resin is used to form a layer of membrane material on the building surface, it can effectively improve the weather resistance (wind erosion resistance and resistance) of the building surface Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings: Introduction: Organosilicon coating is a kind of polymer which is composed of silicon atom and oxygen atom alternately, and different organic groups are connected with silicon atom It is a kind of coating which takes organosilicon polymer or its modified polymer as the main film-forming material It has excellent heat resistance, cold resistance, corona resistance, radiation resistance, hydrophobicity, stain resistance, chemical corrosion resistance, electrical insulation and elasticity In recent years, it has developed rapidly in product modification and application If the silicone resin is used to form a layer of membrane material on the building surface, it can effectively improve the weather resistance of the building surface (wind erosion resistance, rain water immersion resistance and acid rain erosion resistance), which has a certain practical application value for the protection of high-grade buildings, especially ancient buildings The silicone elastic latex building decoration coating is easy to operate and control, with stable product performance, good adhesion, aging resistance, weather resistance, water impermeability and scalability, and can adapt to wall cracking caused by adverse factors and infiltration of seasonal typhoon and rainwater pressure The elastic-plastic silicone "three proofing" coating has good storage stability at room temperature It can be solidified into film at room temperature after adding drier It can be used for moisture-proof treatment of capacitors, impregnation of ceramic porous materials, protective coating of petroleum instruments, as protective material of QM type cardiac pacemaker, and silicone modified polyurethane Paint, etc Organosilicon resin: organosilicon resin is a highly cross-linked network structure of polysiloxane, which is usually a mixture of methyltrichlorosilane, dimethyldichlorosilane, Phenyltrichlorosilane, Diphenyldichlorosilane or methylphenyldichlorosilane In the presence of organic solvents such as methylbenzene, water is added at a lower temperature to decompose to obtain acid hydrolysate The initial product of hydrolysis is a mixture of ring-shaped, linear and cross-linked polymers, usually containing quite a lot of hydroxyl groups The hydrolysate was washed to remove acid, and the neutral prepolymer was oxidized in air or further polycondensated in the presence of catalyst Organosilicon resin has good performance, and the performance comparison with general oil-based resin is shown in the table below Silicone resin coating: the absorption of water by the "breathing" silicone waterproof coating wall material will cause serious damage to the wall itself, and the water in the wall needs to volatilize from the wall material in the form of water vapor through a smooth channel Therefore, reducing the water absorption of building materials and endowing the exterior wall materials with "breathing" function are important ways to improve the decoration and waterproof performance of buildings Organopolysiloxane with certain reactive groups is the main film-forming material of organosilicon coating, its main chain structure has strong chemical affinity, and a small number of active groups on macromolecules react with hydroxyl groups in silicate substrate during the film-forming process Because the coating does not close the capillary channel, the moisture in the substrate can spread out in time to ensure that the substrate has a good "breathing" function The coating can be used for the external wall protection of high-grade buildings The use of silicone resin to form a layer of membrane material on the surface of buildings can effectively improve the weather resistance (wind erosion resistance, rain water immersion resistance and acid rain erosion resistance) of the building surface, which has a certain practical value for the protection of high-grade buildings, especially ancient buildings Organosilicon elastic decorative coating organosilicon latex elastic decorative coating is a new type of film-forming material by introducing organosilicon bond into acrylic resin The addition of organosilicon improves the weatherability and durability of acrylic resin The elongation of the coating film reaches 300% - 700% It covers up the micro cracks on the wall and improves the decorative function of the coating Composite polymer latex solution is prepared by multi-step emulsion polymerization The center is hard resin Compared with ordinary rubber slag, the film has better elasticity and water resistance, higher gloss and hardness, and high stain resistance It is a functional coating with a very promising future Reactive silicon latex solution is polymerized by raw rubber, cross-linking agent and catalyst under certain conditions After dehydrated, the solution can carry out cross-linking reaction at room temperature, forming a whole film of silicon latex with network structure The silicone elastic latex building decoration coating is easy to operate and control, with stable product performance, good adhesion, aging resistance, weather resistance, water impermeability and scalability, and can adapt to wall cracking caused by adverse factors and infiltration of seasonal typhoon and rainwater pressure Among all the "three proofing" coatings, the "three proofing" coating has the best comprehensive performance, which can be cured at room temperature or low temperature and is convenient for construction The cured coating not only has the flexibility of rubber, but also has a smooth and transparent surface, and has the advantages of high and low temperature impact resistance, high frequency dielectric property, excellent "three proofs" performance, etc., which can meet the protection coating of the whole machine in high and low frequency and hybrid circuit The coating is a block copolymer of linear polysiloxane and silicone resin, which is prepared by copolycondensation of linear polysiloxane with different silicone monomers in the presence of solvent under the action of catalyst It is a xylene solution with a resin content of 50% - 60% It has good storage stability at room temperature It can be solidified into a film at room temperature after adding a desiccant It can be used for the moisture-proof treatment of capacitors, the impregnation of ceramic porous materials, the protective coating of stone oil instruments, and the protective material of QM type cardiac pacemaker in electrical, electronic, petroleum, pharmaceutical and other industries Because of its good transparency, dust resistance, atmospheric aging resistance, UV aging resistance and other properties, it is also an ideal material for the outer glass packaging of solar cells Construction of silicone resin coating: ① base treatment: the surface of base course shall be flat, and uneven sanding is not allowed ② Joint treatment: if there is more than 3 mm crack on the roof, the sealing material shall be filled, and then the scratch coating shall be applied ③ Painting and scraping coating: rolling, scraping, painting and brushing can be used for construction, generally 3-4 layers of painting and scraping, and the reference amount of each layer of painting and scraping is 0.8-1.0 kg / m2 ④ The total thickness of the coating film is more than 1.5mm, and the interval of each coating is 2-12h (depending on the weather) 1-2 layers of glass fiber cloth or other matrix materials can be added in the middle of the coating Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating
