Abstract

The invention discloses a flame-retarding aqueous coating used for wood doors. The coating includes, by weight, 60-80 parts of aqueous bisphenol S epoxy resin, 10-20 parts of epoxy acrylate resin, 0.3-0.5 parts of a catalyst, 1-2 parts of maleic anhydride, 1-2 parts of p-phenylenediamine, 1-2 parts of an emulsifier, 2-4 parts of coumarone resin, 40-50 parts of a packing and reinforcing agent, 4-6parts of an anti-settling agent, 2-4 parts of a dispersant, 1.5-2.5 parts of a leveling agent, and 1.5-2.5 parts of a defoamer. The coating has strong adhesion force and can form a full coating film,is free of yellowing and being embrittled, is free of organic solvent, has good heat dissipation effect and excellent flame retarding performance and comprehensive performance and has excellent protection effect on the wood doors. The coating is free of peeling even after long time use of the wood door and also can prevent fire in fire disaster.

Description

technical field [0001] The invention relates to the technical field of wooden doors, in particular to a flame-retardant water-based coating for wooden doors. Background technique [0002] With the improvement of people's quality of life, people's requirements for the wooden doors used are getting higher and higher. Wooden doors not only need to have the characteristics of environmental protection, safety, and durability, but also the coatings on the surface should also have the advantages of environmental protection and durability. Because wooden doors are often exposed to wind and sun during daily use, the coating on the surface tends to turn yellow and emit toxic gases after a long time. In addition, the flame retardant performance cannot meet the demand. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a flame-retardant water-based coating for wooden doors, which has strong coating ...
