Abstract
The invention provides a method for preparing a water-proof plate material by using kaoline as a raw material. The method is characterized by comprising the following steps of: mixing kaoline and an alkali gelatinized starch adhesive, molding, drying and cooling to obtain a plate material; painting a polystyrene methylbenzene solution on the surface of the plate material; and baking in vacuum and recycling the methylbenzene to obtain the water-proof plate material by using kaoline as the raw material. The cost for preparing a plate material by using the method is low, massive kaoline with low price and waste polystyrene foam can be effectively utilized, resources can be reasonably utilized, and a novel water-proof plate material with wide application can be provided.
Description
Technical field
The present invention relates to a kind of preparation method of water-proof sheet material, refer in particular to the method for preparing sheet material with kaolin, alkali pasting starch adhesive, waste polystyrene foam and toluene.
Background technology
The demand that the present invention is primarily aimed at present sheet material increases year by year, and the price of sheet material is also progressively riseing, and sheet material has purposes very widely, is very easy to promotion and application.The waste polystyrene foam has caused serious environmental problem simultaneously, and good film-forming properties and the water tolerance of polystyrene makes it possess the condition of film forming waterproof at plate surface.
Because the present invention utilizes kaolin to be main raw material, kaolin is cheap raw material, the waste polystyrene foam is to have at present extensively, be difficult to again the waste handled, therefore, not only with low cost with these feedstock production sheet materials, and can utilize waste in a large number, satisfy society for the growing demand of sheet material, product of the present invention has broad application prospects in building and finishing field, yet there are no the relevant report of this aspect.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of preparation of plates method, and this preparation method is tackiness agent with the alkali pasted starch, and kaolin is base material, and the toluene solution of waste polystyrene foam prepares water-proof sheet material as waterproof paint through reasonable proportioning.
The technical problem to be solved in the present invention is solved by following scheme: be the method for feedstock production water-proof sheet material with kaolin, it is characterized in that: kaolin is added in the alkali pasting starch adhesive, uniform mixing, through overmolding, heat drying or seasoning, product is taken out, the waterproof paint that the spraying polystyrene foam is made, namely get product through vacuum-drying and recovery toluene, wherein the mass ratio of alkali pasting starch adhesive, kaolin and polystyrene waterproof paint is 1:1.304:0.0174-0.0326.
Above-mentioned is that waste polystyrene foam in the method for feedstock production water-proof sheet material refers to the polystyrene foam that packaging waste polystyrene foam, disposable lunch-box are discarded etc. with kaolin.
Advantage of the present invention is: it is very low 1, to prepare the cost of sheet material with present method.2, can effectively utilize a large amount of inexpensive kaolin.3, with waste polystyrene foam preparation waterproof paint cheaply, prepared sheet material is pollution-free.
