New type fireproof board prepared by waterglass and expanded perlite, but mechanical property is poor and water resistance is bad.It is this kind of multiple to improve
Plate property is closed, improved technical scheme has prepares anti-fire screen using expanded perlite addition high temperature resistant powder and polyvinyl acetate
Hot composite board, compression strength reach 0.81MPa, and fire resistance also improves to some extent.Technical scheme also is by phenol
The good mechanical property of urea formaldehyde and high temperature resistant ablation property, one kind has been prepared using polystyrene foam particles and phenolic resin
Lightweight mixes insulation material, but its anti-flammability needs further to improve.The sheet material that phenolic resin is made possesses good anti-
Fire, the performance of lightweight and insulation, but phenolic foam board mechanical performance is poor is modified, it is necessary to add filler, conventional filler
For wood powder or rubber powder, the improvement unobvious to phenolic foam board mechanical performance.
The content of the invention
It is an object of the invention to overcome defect present in prior art, there is provided a kind of phenolic foam board mixing filling
Agent, the filler is added in phenolic resin batch mixing, foaming gained sheet material has good mechanical performance.

It is, it, which forms fraction by weight, includes wood powder or 30~40 parts of bamboo powder, 40~60 parts of inorganic powder, natural resin or oil tree
10~23 parts of fat, 5~10 parts of rubber powder, 0.5~3 part of coupling agent, the wherein material of rubber powder be EP rubbers, nitrile rubber, organic
At least one of silicon rubber, polysulfide rubber, natural resin are at least one of rosin resin and kopol.
Preferable technical scheme is that wood powder is the bark powder selected from larch, pinus sylvestris var. mongolica, elm, willow, eucalyptus and maple
At least one of.
Preferable technical scheme is, inorganic powder be selected from natural sodium bentonite, powdered whiting, precipitated calcium carbonate,
At least one of hydrotalcite powder, diatomite, attapulgite.
Preferable technical scheme is that inorganic powder is that powdered whiting and diatomite combine, diatom in inorganic powder
The weight score ratio of soil is 35~55%.
Preferable technical scheme is that the particle diameter of wood powder or bamboo powder is 70~120 mesh；The particle diameter of inorganic powder is 150~200
Mesh.
Preferable technical scheme is that coupling agent is selected from silane coupler, titanate coupling agent, aluminate coupling agent or boron
One or more of mixtures in acid esters coupling agent.
Preferable technical scheme is that coupling agent is answered by amino-alkyl silicane and monoalkoxy Pyrophosphate Type Yitanate Coupling Agent
With into the percentage by weight of monoalkoxy Pyrophosphate Type Yitanate Coupling Agent is 10~30% in coupling agent.
The advantages of the present invention are：
Phenolic foam board mixed filler of the present invention is mixed by wood powder or bamboo powder, inorganic powder, resin and rubber powder, can
The toughness and rigidity of phenolic resin foamed board are balanced, reduces the solidification temperature of Foaming of phenolic resin plate, reduces bow warping phenomenon.
