Paint knowledge | adhesive classification by material source

Core tip: there are many kinds of adhesives, which can be generally classified as follows: according to the source of materials ① natural adhesives are derived from natural substances Including starch, protein, dextrin, animal glue, shellac, leather glue, rosin and other biological adhesives; also including asphalt and other mineral adhesives ② Artificial adhesive this is a material made by man, including inorganic adhesive such as water glass, and organic adhesive such as synthetic resin and synthetic rubber According to the use characteristics, the water-soluble adhesives are mainly starch, dextrin, polyvinyl alcohol, carboxymethylcellulose, etc ② The hot-melt adhesive is used after the adhesive is melted by heating Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: there are many kinds of adhesives, usually can be classified as follows: according to the source of materials ① natural adhesives it comes from natural substances Including starch, protein, dextrin, animal glue, shellac, leather glue, rosin and other biological adhesives; also including asphalt and other mineral adhesives ② Artificial adhesive this is a material made by man, including inorganic adhesive such as water glass, and organic adhesive such as synthetic resin and synthetic rubber According to the use characteristics, the water-soluble adhesives are mainly starch, dextrin, polyvinyl alcohol, carboxymethylcellulose, etc ② The hot-melt adhesive is a solid adhesive, which is used after the adhesive is melted by heating General thermoplastic resins can be used, such as polyurethane, polystyrene, polyacrylate, ethylene vinyl acetate copolymer, etc ③ A binder that is insoluble in water and soluble in a solvent Such as shellac, butyl rubber, etc (4) emulsion adhesive is suspended in water, such as vinyl acetate, acrylic resin, chlorinated rubber, etc ⑤ Solventless liquid adhesive is viscous liquid at room temperature, such as epoxy resin The adhesive is the medium between the label material and the bonding base material, which plays a role of connection According to its characteristics, it can be divided into permanent and removable It has a variety of formulas, suitable for different surface materials and different occasions Adhesive is the most important component of adhesive material technology, and it is the key of label application technology 1 ms modified silane modified silane polymer end is methoxysilane according to raw materials, 1978 Invented by Zhongyuan group in, the company is the only supplier of modified silane raw materials in the world On this basis, through continuous R & D and innovation, novan technology of Belgium has produced a series of high-quality sealants and adhesives for construction, industry, automobile transportation, civil use, etc Polyurethane polyurethane, which is called polyurethane, is a general designation of macromolecular compounds containing repeated carbamate groups in the main chain It is formed by the addition of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compounds 3 silicones, commonly known as silicone oil or dimethylsilicone oil, has the formula: (CH3) 3sio (CH3) 2SiO NSI (CH3) 3, which is a polymer of organosilicon oxide, a series of polydimethylsiloxanes with different molecular weight, and the viscosity increases with the increase of molecular weight Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
