    It is suggested that non intumescent fire retardant coating is composed of flame retardant or non combustible resin, flame retardant, fire-retardant filler, etc (1) the main film forming material: flame retardant resin, usually composed of halogenated, phosphorus, nitrogen and other polymer synthetic resins, such as halogenated alkyd resin, polyester, epoxy, phenolic, chlorinated rubber, neoprene rubber, polyacrylate emulsion, VAE emulsion, etc In addition, inorganic materials such as water glass, silica sol and phosphate can be used as film-forming materials of inorganic fire-retardant materials The coating layer composed of them has the characteristics of non flammability, non smoke and non-toxic (2) Flame retardant 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 Coating home news: non intumescent fire retardant coating is composed of flame retardant or non combustible resin, flame retardant, fire filler, etc (1) the main film forming material: flame retardant resin, generally composed of halogenated, phosphorus, nitrogen and other polymer synthetic resins, such as halogenated alkyd resin, polyester, epoxy, phenolic, chlorinated rubber, neoprene rubber, polyacrylate emulsion, VAE emulsion, and other water glass , silica sol, phosphate and other inorganic materials can be used as film-forming materials of inorganic fire-retardant materials The coating layer composed of them has the characteristics of non combustion, non smoke and non-toxic (2) Flame retardant: flame retardant increases the flame retardancy of the coating Commonly used are: organic compounds containing phosphorus and halogen, such as chlorinated paraffin, decabromodiphenyl ether, phosphophenol Trichloroacetaldehyde ester, etc In addition, there are antimony series, boron series (boric acid, borax, zinc borate, aluminum borate), aluminum series, zirconium series (zirconia) and other inorganic flame retardants The application of antimony trichloride in combination with resin containing halogen can often obtain better flame retardancy (3) Fireproof filler: common inorganic pigments and fillers are non combustible or low thermal conductivity and heat insulation, which can increase the flame resistance of the coating Commonly used are vermiculite, perlite, mica powder, talc powder, kaolin, zinc oxide, titanium dioxide, calcium carbonate, aluminum hydroxide, zinc borate, antimony trioxide, etc (4) Auxiliaries: in order to meet other performance requirements of fire retardant coating, some auxiliaries, such as plasticizer, dispersant, defoamer, film-forming auxiliaries, etc., need to be used Formula example 1 Inorganic non intumescent fire retardant coating for interior wall composition / mass fraction 85% phosphoric acid 2 water 41 water containing aluminum phosphate 57 nonylphenol 0.15 isopropanol 1.65 rutile 38.9 Process and performance: mix phosphoric acid, aluminum phosphate and water, heat and melt them, add nonylphenol and isopropanol to room temperature, mix them evenly, then add rutile soaked in water, speed up mixing the mixture, and mix them to form decorative fire retardant coating Brush the finished product on the dry wall The wall is exposed to an open fire at 500 ℃ without burning At this time, there is no flame on the dry wall and only a small amount of smoke is generated This product is widely used in interior wall decoration and painting of high-grade buildings, fire-proof warehouses, etc White water-based building fire retardant coating composition dosage / weight: 85% phosphoric acid 1.4 water 29.3 aluminum phosphate (including 3 crystal water) 40.5 nonylphenol 0.1 isopropanol 1.2 rutile titanium dioxide 27.5 process and performance this product is mainly used for building surface fire retardant coating, which can be used as decorative coating alone, as bottom coating, and other coating above 2 Waterborne non intumescent fire-retardant coatings, non expansive latex fire retardant coating composition / mass fraction antimony oxide 9.2 five brominated toluene 4.2 titanium dioxide 140 porcelain clay 35 mica 39.2 hydroxyethyl cellulose 1.7 surface wetting agent 1.8 acrylic plasticized emulsion (solid 56% 56%) 165.5 calcium carbonate 165.5 water, solvent based non expansion fire retardant coating for interior wall fire retardant coating composition Dosage / weight: 50% alkyd resin, 80 titanium dioxide, 100 starch, 366 ammonium phosphate, 233 aminoacetic acid, 43.3 chlorinated rubber, 83.3 60% organosilicon resin, 5-8 naphthalene solvent, 200 (the formula in this paper is for reference only) The home of coatings focuses on coatings, diatom mud, paint coating, coating technology, news and coating of fireproof coating, diatom mud, paint coating, coating technology, decoration of fireproof coating Knowledge and decoration renderings,
