Abstract
The invention relates to a method for preparing a board from waste polyurethane foam, kaolin and waste polystyrene foam. The technical process mainly comprises the following steps: adding waste polyurethane foam powder and kaolin into a bonding agent prepared by dissolving waste polystyrene foam in toluene, uniformly mixing, forming in a mold, and recovering the toluene under the conditions of reduced pressure and heating, thereby obtaining the board. The board prepared from the waste polyurethane foam, kaolin and waste polystyrene foam by the method is very low in cost, can effectively utilize abundant waste polystyrene foam and waste polyurethane foam, reasonably utilizes the resources and reduces the pollution caused by waste, thereby providing a novel broad-spectrum waterproof board.
Description
Technical field
The present invention relates to a kind of preparation of plates method, refer in particular to the method for preparing sheet material with waste polyurethane foam, kaolin and waste polystyrene foam.
Background technology
The demand increase year after year of current sheet material, and the price of sheet material is also progressively riseing, the sheet material of lightweight and insulation has purposes widely simultaneously, is very easy to promotion and application.
The present invention is that to take waste polyurethane foam, kaolin and waste polystyrene foam be main raw material.Kaolin is cheap raw material, and good plasticity-and high cohesiveness are arranged, and waste polyurethane foam and waste polystyrene foam are the main wastes that causes environmental pollution, are not rationally utilized.Yet there are no the relevant report for preparing sheet material with waste polyurethane foam, kaolin and waste polystyrene foam, and its cheap cost makes it have broad application prospects in building and finishing field.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation of plates method, and this method prepares sheet material with waste polyurethane foam, kaolin and waste polystyrene foam raw material.
The technical problem to be solved in the present invention is solved by following scheme: the waste polyurethane foam is pulverized and to be obtained waste polyurethane foam powder, and the waste polystyrene foam of take prepares tackiness agent as raw material.It is characterized in that: the waste polystyrene foam is dissolved in toluene and prepares tackiness agent, add waste polyurethane foam powder, kaolin, after uniform mixing, moulding, decompression and heating recovery toluene, obtain sheet material.
Advantage of the present invention is: the board cost 1, prepared by present method is very low.2, can effectively utilize a large amount of waste polyurethane foams and a large amount of waste polystyrene foams.3, make rational use of resources and alleviate the pollution that waste causes.4. prepared sheet material can waterproof.
The accompanying drawing explanation
Fig. 1. prepare the process flow sheet of sheet material with waste polyurethane foam, kaolin and waste polystyrene foam.
