Abstract

The invention discloses a preparation method of intumescent fire-retardant paint. The intumescent fire-retardant paint is prepared from an ethene-vinyl acetate copolymer emulsion and modified resin as base materials, melamine and cyanoguanidine as foaming agents, pentaerythritol as a charring agent, ammonium polyphosphate as a dehydration charring catalyst, chlorinated paraffin as a fire retardant, silica and titanium dioxide as filling materials and other auxiliary agents. The aqueous emulsion and modified resin are blended to form the base materials so that xylene release damage is prevented in fireproof paint production, storage, transport, construction and use. The preparation method saves a production cost, is convenient for production construction and has no fire hazard risk. The intumescent fire-retardant paint has excellent performances and a wide application range. The intumescent fire-retardant paint satisfies requirements in the finishing fire-retardant paint general technical specification GB 12441-1998, exceeds standard technical indexes of the finishing fire-retardant paint general technical specification GB 12441-1998, satisfies requirements in the steel structure fire-retardant paint general technical specification GB 14907-94 and exceeds standard technical indexes of the steel structure fire-retardant paint general technical specification GB 14907-94.

Description

technical field [0001] The invention relates to the production technology category of fireproof coatings, in particular to a preparation method of intumescent fireproof coatings. 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 the external fire source. The components of the coating undergo physical and chemical changes under the...
