Abstract
以废弃聚氨酯泡沫及废弃聚苯乙烯泡沫来制备板材的方法。主要工艺过程是：废弃聚苯乙烯泡沫溶于甲苯制得粘合剂，加入废弃聚氨酯泡沫粉，拌和均匀，在模具中成型，减压及加热下经过冷凝回收甲苯，即得产品。以废弃聚氨酯泡沫及废弃聚苯乙烯泡沫为原料制备的板材成本很低，可以有效利用大量废弃聚苯乙烯泡沫、废弃聚氨酯泡沫，合理利用了资源并减轻废弃物造成的污染，提供了一种用途广泛的新型防水板材。The invention discloses a method for preparing boards from waste polyurethane foam and waste polystyrene foam. The main process is: dissolving waste polystyrene foam in toluene to make an adhesive, adding waste polyurethane foam powder, mixing evenly, forming in a mold, and recovering toluene through condensation under reduced pressure and heating to obtain the product. The cost of the board prepared from waste polyurethane foam and waste polystyrene foam is very low, and a large amount of waste polystyrene foam and waste polyurethane foam can be effectively used, and resources are rationally used and pollution caused by waste is provided. Extensive range of new waterproofing panels.
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 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 and waste polystyrene foam be raw material.Waste polyurethane foam and waste polystyrene foam are the main wastes that causes environmental pollution.Yet there are no the relevant report for preparing sheet material with waste polyurethane foam 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 be take waste polyurethane foam and waste polystyrene foam and prepared sheet material as raw material.
The technical problem to be solved in the present invention is solved by following scheme: the waste polyurethane foam is pulverized and obtained waste polyurethane foam powder, using it as base material, take the waste polystyrene foam as raw material prepares tackiness agent again, then with above-mentioned base material and tackiness agent, prepare sheet material.It is characterized in that: the waste polystyrene foam is dissolved in toluene and prepares tackiness agent, add waste polyurethane foam powder, uniform mixing, moulding, recovery toluene, obtain product.
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 waste polystyrene foam.3, make rational use of resources and alleviate the pollution that waste causes.4. prepared board quality is light also can waterproof.
The accompanying drawing explanation
Fig. 1. prepare the process flow sheet of sheet material with waste polyurethane foam and waste polystyrene foam.
Embodiment
The preparation of tackiness agent: take 23.30g waste polystyrene foam and join in 50.0ml toluene, stir and make its dissolving obtain tackiness agent.
Embodiment 1: in the 12.94g tackiness agent, add 3.00g waste polyurethane foam powder, and uniform mixing, in die for molding, decompression and heating are lower reclaims toluene through condensation, obtains product.
Embodiment 2: in the 12.94g tackiness agent, add 2.50g waste polyurethane foam powder, and uniform mixing, in die for molding, decompression and heating are lower reclaims toluene through condensation, obtains product.
Embodiment 3: in the 12.94g tackiness agent, add 2.00g waste polyurethane foam powder, and uniform mixing, in die for molding, decompression and heating are lower reclaims toluene through condensation, obtains product.
Embodiment 4: in the 12.94g tackiness agent, add 1.50g waste polyurethane foam powder, and uniform mixing, in die for molding, decompression and heating are lower reclaims toluene through condensation, obtains product.
Embodiment 5: in the 12.94g tackiness agent, add 1.00g waste polyurethane foam powder, and uniform mixing, in die for molding, decompression and heating are lower reclaims toluene through condensation, obtains product.
