Abstract

The multipurpose expanding fireproof paint is compounded with ethylene-vinyl acetate copolymer emulsion and modifying resin as basic material, cyanuramide and dicyandiamide as foaming agent, pentaerythrite as carbonizing agent, polyammonium phosphate as dewatering and carbonizing catalyst, chlorinated paraffin as fire retardant, silica and titania powder as stuffing, and other assistant. It has excellent fireproof performance, no harm of xylene, low cost and wide use.

Description

technical field [0001] The present invention relates to the production technology category of fireproof paint, specifically, relates to the production technology category of intumescent fireproof paint, including decorative surface fireproof paint and steel structure fireproof paint. Background technique [0002] At present, the intumescent fireproof coatings used in building fireproofing projects at home and abroad can be divided into two categories: facing fireproofing coatings and steel structure fireproofing coatings, each of which has many varieties. Generally speaking, the reason why fire retardant coatings can prevent fire is that after the coating is formed into a film, it is an ordinary paint film at room temperature. Under flame or high temperature, the coating expands and carbonizes, forming a hard film dozens of times thicker than the original film. Burning spongy carbonaceous layer. It can isolate the heat transfer and flame retardancy of the base material from...
