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, supplemente

Example Embodiment

[0028] Example one

[0029] The formula is as shown in Table 3:

[0030] raw material name phr Remarks Polyurethane resin 100 Adhesive Methyl ethyl ketone 100 Solvent water 200 Solvent Melamine 100 Foaming agent Urea 100 Foaming agent Isoprene 120 Carbonizing agent Phosphorus titanate 60 Carbonization accelerator

Example Embodiment

[0031] Example two

[0032] The formula is as follows in Table 4:

[0033] raw material name phr Remarks Polyurethane resin 100 Adhesive Methyl ethyl ketone 100 Solvent water 200 Solvent Melamine 100 Foaming agent Urea 100 Foaming agent Isoprene 120 Carbonizing agent Phosphorus titanate 60 Carbonization accelerator Nano Mica 12 Auxiliary additives

[0034] Preparation method

[0035] The foaming agent and carbonizing agent of the above formula raw materials, if necessary, use auxiliary additives, and the solvent is fully mixed and dispersed at room temperature, then the carbonization accelerator is added and mixed, and finally the binder is added and mixed.

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.
