Decorative finish expansive type waterborne polyurethane modified acrylate woodware fireproof coating

Abstract

The invention provides decorative finish expansive type waterborne polyurethane modified acrylate woodware fireproof coating which is prepared from the following raw material ingredients in parts by weight: 50 to 80 parts of woodware coating resin, 20 to 30 parts of ammonium polyphosphate, 8 to 12 parts of tripolycyanamide, 5 to 8 parts of pentaerythritol, 8 to 12 parts of titanium dioxide, 3 to 6parts of dispersing agent, 0.1 to 0.3 part of leveling agent, 0.1 to 0.3 part of defoaming agent, 2 to 4 parts of thickening agent, 0.1 to 0.3 part of preservative, 1.0 to 2.5 parts of coalescing agent, 0.1 to 0.3 part of wetting agent, 0.2 to 0.5 part of OP-10 emulsifier and 30 to 50 parts of deionized water.

Description

technical field [0001] The invention relates to a fireproof coating, in particular to a facing expansion type waterborne polyurethane modified acrylic fireproof coating for woodware. Background technique [0002] Fire retardant coating is to brush the paint on the surface of those flammable materials, which can improve the fire resistance of the material, slow down the speed of flame spread, or prevent burning within a certain period of time. This type of coating is called fire retardant coating, or flame retardant coating. Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. It is applied to the surface of flammable substrates to change the combustion characteristics of the material surface and retard the rapid spread of fire; or applied to building components to improve the fi...

AI Technical Summary

Problems solved by technology

This kind of decorative expansion type water-based polyurethane modified acrylic wood fireproof coating adopts acrylic mixed monomer and water-based polyurethane dispersion emulsion with good performance in all aspects as the base material, and uses water as the dispersant. It is poisonous and harmless, convenient for construction, easy to store, and has good fire-proof and flame-retardant performance. The intumescent fire-proof coating of the present invention not only overcomes the shortcomings of poor thermal stability of existing fire-proof coatings, but also has good fire-proof and heat-insulating performance, excellent adhesion Good, high strength, can withstand the influence of high and low temperature cycles, the coating has good water resistance, acid resistance, salt corrosion resistance, not easy to fall off, stable storage, good decoration, no smoke or less smoke generation when burning, etc.
