Abstract

The invention discloses a method for preparing a woodworking adhesive by taking toluene and ethyl acetate as a mixed solvent, neoprene and waste polystyrene foam as adhesives and aluminum oxide as filler. The main process comprises the following steps of: adding neoprene into the mixed solvent of toluene and ethyl acetate; standing overnight; heating while stirring; stirring at certain temperature; adding the waste polystyrene foam, and stirring to dissolve the waste polystyrene foam; adding the aluminum oxide powder, and continuously stirring; and discharging and packaging to obtain a product.

Description

technical field [0001] The invention relates to a woodworking adhesive preparation method, in particular to a method for preparing the adhesive by using waste polystyrene foam, neoprene rubber, aluminum oxide and toluene as main raw materials. Background technique [0002] The present invention mainly aims at the severe pollution caused by waste polystyrene foam, which has not been rationally utilized, and at the same time, the price of woodworking adhesive is too high due to the rising price of neoprene rubber. The use of waste polystyrene foam to replace part of the neoprene makes the cost significantly reduced. [0003] Because the present invention utilizes waste polystyrene to prepare woodworking adhesives as part of the raw material, the method is low in cost, and there is no relevant report on this aspect at present, and its unique performance makes it widely used in furniture manufacturing and decoration. application prospects.
