Abstract

The invention discloses a kind of preparation method of phenolic resin modified tri compound sheet material, including dry filler, prepare resin batch mixing and the step of molded curing three.The preparation method step of the phenolic resin modified tri compound sheet material of the present invention is simple, by introducing filler and natural plant fibre into phenolic resin, Two dimensional Distribution form is presented in fiber with certain length in sheet material, the mechanical property in rift grain direction is given full play to, improve the impact strength of sheet material, in addition, tri compound sheet material also has good heat-insulating property.

Description

A kind of preparation method of phenolic resin modified tri compound sheet material
Technical field
The present invention relates to composite board technical field, and in particular to a kind of preparation of phenolic resin modified tri compound sheet material Method.
Background technology
Traditional insulation material such as polystyrene foam, polyurethane foam organic material still exists in fire protecting performance Some shortcomings, and some inorganic heat insulation materials such as rock wool etc. is unfavorable for the physical and mental health of workmen, has used on the market 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, the improved technical scheme of stone has prepares fire prevention using expanded perlite addition high temperature resistant powder and polyvinyl acetate Heat insulation composite board, compression strength reach 0.81MPa, and fire resistance also improves to some extent.Technical scheme also by The good mechanical property of phenolic resin and high temperature resistant ablation property, one has been prepared using polystyrene foam particles and phenolic resin Kind lightweight mixing insulation material, but its anti-flammability needs further to improve.The sheet material that phenolic resin is made possesses.Good The performance of fire prevention, lightweight and insulation, but phenolic foam board cost is high, and preparation technology is complicated, significantly limit it in many sides The application in face.
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 resin modified tri compound The preparation method of sheet material, this method step is simple, suitable for industrialized production.
To realize above-mentioned technique effect, the technical scheme is that:A kind of phenolic resin modified tri compound sheet material Preparation method, it is characterised in that comprise the following steps:
S1:Filler is placed at 105~110 DEG C and dries 2~3h;
S2:Resin batch mixing is configured, absolute ethyl alcohol dilution is added thereto, by filler and natural plant fibre and phenolic resin Ethanol solution stirs;
S3:According to 1: the compression ratio of (1.2~1.5) be placed in steel mould molding it is smooth, be placed in 160~180 DEG C of baking ovens Curing molding, obtain phenolic resin modified tri compound sheet material;
Wherein, the percentage by weight of filler is 20~30% in phenolic resin modified tri compound sheet material, the weight of fiber Percentage is 4~9%.
Preferable technical scheme is that natural plant fibre is fine selected from sisal fiber, banana fiber, pina fibre, palm At least one of dimension.
Preferable technical scheme is that filler is at least one in bamboo powder, wood powder, glass microballoon, rice husk meal, powder of straw Kind.
Preferable technical scheme is that the particle diameter of filler is 60~100 mesh.
