The beneficial effects of the invention are as follows：
Technical solution of the present invention, first, phenol are mixed with polyethylene glycol, are liquefied through sulfuric acid catalysis, so with formalin and more
Polyformaldehyde reaction generation phenolic resin, the phenolic resin of generation form water-in-oil emulsion so that generation through emulsifier
Phenolic resin is dispersed in system, adds in demulsifier afterwards so that and the phenolic resin after demulsification is preferably penetrated into wood powder,
Secondly, by the stifling of the nitrogen containing trimethyl aluminium, trimethyl aluminium reacts generation methane and aluminium hydroxide with the water in system, and
A large amount of heat is released, the methane gas of generation plays good foaming effect, promotes the hole in wood powder liquefied resin foam
Gap rate, promotes the heat-insulating property and sound insulation value of system, in addition, being added to carbomer in system, contains in carbomer molecular structure
There are a large amount of carboxyls, the aluminium hydroxide of part generation can be reacted with carbomer, make part carboxylic ions in carbomer, another part
Aluminium hydroxide is thermally decomposed to generate aluminium oxide, and the aluminium oxide of generation is adsorbed by the carboxyl of unionization in carbomer, due to card wave
Part carboxylic ions in nurse molecular structure generate negative electrical charge, and repulsive interaction causes carbomer molecule between negative electrical charge
Structure good dispersion in system is unfolded, so that the aluminium oxide of generation is uniformly dispersed being filled in system, reinforcement
It is mechanical property, meanwhile, the flame retardant property of system is promoted, furthermore, a large amount of heat of trimethyl aluminium and water reaction generation can promote
Make the further crosslinking curing of phenolic resin, further enhance the mechanical property of system.
