Fireproof coating for environment-friendly wooden doors

Abstract

The invention discloses a fireproof coating for environment-friendly wooden doors, made from, by weight, 3-6 parts of chitin, 3-8 parts of a nitrogenous flame retardant, 15-35 parts of waterborne resin, 0.3-0.5 part of a defoaming agent, 2-5 parts of a leveling agent, 1-3 parts of a rheological agent, 20-25 parts of water, 1-3 parts of organosilicon-modified styrene-acrylic emulsion, 1-3 parts ofa film-forming aid, 10-14 parts of a pigment filler, 1-5 parts of ammonium polyphosphate, 8-10 parts of a binder, and 2-4 parts of nano formaldehyde-removing inorganic silicon sheeting. The nitrogenous flame retardant is melamine phosphate; the defoaming agent is a span or tween agent; the leveling agent is polymethylphenylsiloxane; the rheological agent is polyethylene wax; the film-forming aid is propylene glycol; the pigment filler is ferric oxide. The fireproof coating is safe to human health, can prevent a fire on environment-friendly wooden doors and never assist in increasing fire spread.

Description

technical field

[0001] The invention belongs to the field of coatings for indoor wooden doors, and in particular relates to a fireproof coating for environmentally friendly wooden doors. Background technique

[0002] Environmentally friendly wooden doors refer to a type of wooden doors that release less formaldehyde among indoor wooden doors. The door body is usually made of solid wood and environmentally friendly paint is used as a coating. Though the formaldehyde that existing environmental protection paint discharges is less, because still indispensable can add a little binder in the environmental protection paint, binder can release a small amount of formaldehyde, still can cause certain harm to human health. In addition, the environmentally friendly paint itself is flammable. When a fire occurs, it will not only prevent the environmentally friendly wooden door from igniting, but also play a certain role in supporting the fire. Therefore, existing environmental protecti...
