Abstract
The invention discloses a method for preparing a polyvinyl chloride plastic adhesive from waste polystyrene foam and waste polyvinyl chloride. The main process of the method comprises the following steps of: dissolving polyvinyl chloride in the mixed solvent of cyclohexanone and tetrahydrofuran, adding dibutyl phthalate to form a polyvinyl chloride solution, adding waste polystyrene foam in methylbenzene to form a polystyrene solution; and mixing the solutions aforementioned, and uniformly stirring to obtain the polyvinyl chloride plastic adhesive.
Description
Technical field
The present invention relates to a kind of preparation method of the tackiness agent for igelite, referring in particular to waste polystyrene foam and waste polyvinyl chloride is the method that main raw material prepares the igelite tackiness agent.
Background technology
The present invention is primarily aimed at the severe contamination that waste polystyrene foam and waste polyvinyl chloride plastics cause, and rationally do not utilize, while is because polrvinyl chloride product is soaring year by year with the usage quantity of tackiness agent, and the price of the polyvinyl chloride adhesive on the present market is too high.Utilize waste polystyrene foam and waste polyvinyl chloride as the raw material of preparation tackiness agent, can be so that the cost of igelite tackiness agent descends greatly.
Because the present invention utilizes waste polystyrene foam and waste polyvinyl chloride to prepare the igelite tackiness agent, so this method is with low cost, yet there are no the relevant report of this aspect, and its particular performances has broad application prospects it.
Summary of the invention
The technical problem to be solved in the present invention provides and a kind ofly prepares the igelite tackiness agent with waste polystyrene foam and waste polyvinyl chloride, this preparation method substitutes the part polyvinyl chloride with the waste polystyrene foam, through reasonable proportioning, make the igelite tackiness agent by certain technological process.
The technical problem to be solved in the present invention is solved by following scheme: waste polystyrene foam and waste polyvinyl chloride prepare the igelite tackiness agent, it is characterized in that: pimelinketone and tetrahydrofuran (THF) are mixed with mixed solvent, add waste polyvinyl chloride, placement is spent the night, under stirring it is fully dissolved, add dibutyl phthalate, stir, make polyvinyl chloride solution; In toluene, add the waste polystyrene foam, stir and made its dissolving in 1 hour, make polystyrene solution; Polyvinyl chloride solution and polystyrene solution are mixed, stirred 0.5 hour, discharging, packing namely gets product, and wherein the mass ratio of pimelinketone, tetrahydrofuran (THF), waste polyvinyl chloride, dibutyl phthalate, toluene and waste polystyrene is 1:1:0.4: 0.04:2:0.4-2.0.
The waste polyvinyl chloride that above-mentioned waste polystyrene foam and waste polyvinyl chloride prepare in the igelite tackiness agent refers to waste polyvinyl chloride tubing, sheet material and film etc., and the waste polystyrene foam refers to: the waste polystyrene foam that wrapping waste polystyrene foam and disposable lunch-box are used etc.
Advantage of the present invention is: 1, because with waste polystyrene foam instead of part polyvinyl chloride, particularly the dissolved polystyrene foam can use cheap toluene, therefore can reduce the usage quantity of pimelinketone and tetrahydrofuran (THF), it is very low to prepare the cost of polyvinyl chloride adhesive with present method.2, a large amount of waste polystyrene foams that can effectively utilize the city to produce are made rational use of resources and are alleviated the pollution that waste causes.
