Transparent halogen-free fire-resisting paint constituent

Abstract

The invention provides a transparent halogen-free fire-retardant paint composition, which consists of 100phr (Parts per Hundred of Resin) of adhesive, 50-400phr of solvent, 50-300phr of foaming agent, 10-200phr of carburetant, 1-100phr of carbonizing promoter and 0-100phr of auxiliary additive; wherein, the carbonizing promoter is a phosphorus-containing compound with reaction functional groups. A coat formed by the transparent halogen-free fire-retardant paint composition nearly generates no smoke when being heated but instantly generates an expanding layer of high toughness. The expanding layer is not likely to crack, does not melt, drop and droop and moreover, is capable of effectively obstructing oxygen and heat to fulfill fire-retardant effect. The paint composition has excellent compatibility and dispersibility among the ingredients, therefore has eminent transparency and can be used for the fire prevention of various buildings, furniture or in decoration without damaging the original appearance view thereof.

Description

technical field [0001] The invention relates to a transparent halogen-free fireproof coating composition. The coating formed by the composition is almost smoke-free when heated, and can quickly form a high toughness, not easy to crack, not melt, and not drip. The expansion layer can effectively block oxygen and heat to achieve fireproof effect; and the compatibility between the components of the coating is very good, and the dispersion is good, forming superior transparency, which can be applied to various buildings, furniture or decorations It is fireproof and will not damage its original appearance. Background technique [0002] Due to the rapid growth of the global economy and the rapid development of the construction industry, the building materials or decoration materials used are mostly wood and polymer materials, but generally these materials are flammable. When a fire occurs, the flames spread rapidly. unstoppable. In recent years, people have gradually paid attent...

Problems solved by technology

[0005] For example, China Taiwan Patent Announcement 419514 is a foamed fireproof coating, in which polyphosphate amine is used as a carbonization accelerator, and the fireproofness is insufficient. In addition, expandable graphite is used to increase the strength and toughness of the coke expansion layer, but adding graphite will cause coating If it turns black, it will cause the base material of the coated part not only to lose its original style, but also to turn the surface black and unsightly

[0006] For example, China Taiwan patent announcement 499469 is based on water-based phosphorus-containing epoxy resin and melamine, supplemented with pentaerythritol, which is a foaming fireproof coating, but the compatibility between the three components is not good, and the coating is white and opaque.

[0007] For example, U.S. Patent No. 5,225,464 is a water-based intumescent fireproof coating, which is based on phosphoric acid, melamine, ammonium phosphate, and pentaerythritol, and ammonium phosphate is used as a carbonization accelerator. Because of the poor flame resistance, chlorine compounds are added. An improved intumescent coating has been obtained, but its main disadvantage is that it contains halogen (chlorine), which cannot meet environmental protection requirements
