Environment protection type wall covering decorative fireproof coating and preparation method thereof
Technical field
The invention belongs to building coating and its preparing technical field, more particularly to a kind of environment-friendly type for being suitable for wall decoration is prevented
Fiery coating.
Background technology
Fireproof coating is, for flammable substrates surface, to reduce by the combustibility of painting material surface, block the fast of fire
Speed spreads, to improve by a kind of sapecial coating of painting material fire endurance.Can be divided into by purposes and using the difference of object:Decorations
Face type fireproof coating, cable fire-refractory coating, fire-resistant coating for steel structure, prestressed concrete floor slab fireproof coating etc..Wherein facing
Type fireproof coating is increasingly paid attention in building coating industry.But focusing on decoration effect decorated wall surface fireproof coating at present more
Really, flameproof effect is not ideal.
At home in building decoration regulation, the requirement to wall covering is only to specify that interior wall is applied in GB/T9756-2001
Material physical and chemical index, does not refer to fire protection requirement;And requirement of the domestic fire codes to finishing fire retardant paint is
GB12441-1998 also specify only fire protecting performance index, and its physical and chemical index refers to items specified in GB/T9756-2001
Mark greatly differs from each other.So cause fire prevention Finishing coating physical and chemical index on the market and the fire line can not be all good, and
And part coatings are raw materials used not environmentally, meeting fire burning can more produce the organic volatile (VOCs) of high concentration, or even emerge black
Cigarette, this is very unfavorable to the victim and rescue personnel in fire.How wall covering is accomplished the effect of fire protection flame retarding
Not losing the decorative effect and environment protection health of wall covering again simultaneously becomes the design concept and design key of the present invention.
The content of the invention
