Abstract

The invention discloses a PS adhesive. The adhesive comprises recycled PS foam, cyclohexanone and methylbenzene, wherein the recycled PS foam is neatened, classified, washed, aired and crushed into small pieces, used for replacing industrial resin and used as a solid component. A preparation method of the PS adhesive comprises the following steps: stirring 28% of cyclohexanone and 72% of methylbenzene according to the weight percentage in an open metal container at a slow rate, dissolving the crushed PS pieces until the liquid is of a sticky adhesive shape, filtering and removing impurities of the liquid to obtain the PS adhesive.

Description

PS tackiness agent

Technical field

The present invention relates to a kind of polystyrene tackiness agent, specifically refer to the polystyrene special-purpose adhesive made with discarded PS foam, belong to resource regeneration.

Background technology

Annual discarded PS foam is countless, becomes white pollution.And use resin of industry during the polystyrene adhesive producing of traditional way.Replace resin of industry namely to save social resources with discarded PS foam, reduce again plastic refuse to the pollution of environment.

Summary of the invention

The invention provides a kind of method of producing polystyrene tackiness agent without resin of industry, namely replace resin of industry completely with PS foam recovery material.

Technical scheme of the present invention is: the component of tackiness agent is made up of the PS foam reclaimed, pimelinketone, toluene.After clearing up classification, cleaning, airing, being broken into fritter, substitute resin of industry by the PS foam reclaimed and make solid constituent; By weight percentage, pimelinketone 28%, toluene 72%, in open metal container when low rate mixing, dissolves PS fragment and becomes thickness gluey to liquid, remove impurity after filtration and be PS tackiness agent.

The invention has the beneficial effects as follows: recycle renewable resources, alleviate refuse treatment burden, reduce the industrial chemicals consumption such as resin of industry, reduce product cost.

embodiment:

First the PS bubble sort will reclaimed, namely separately clean PS foam and the PS foam that need clean, the PS foam segment that need clean cleaning airing; Then it is for subsequent use that clean PS foam and the PS foam through cleaning airing are broken into fritter respectively.

By weight percentage, the toluene mixing of the pimelinketone of 28% and 72% is placed in the large metal bucket of opening, preparation low rate mixing machine, add PS foam fragment when stirring and carry out stirring and dissolving, foam is soon by organic solvent dissolution, liquid is progressively retrogradation also, is dissolved into liquid always and becomes thick and can use.

If with clean foam dissolve, can directly enter finished product packing program; If dissolving with the foam through cleaning airing, also should program leach residual impurity and can enter finished product packing program for finished product after filtration.

Claims

1. a PS tackiness agent, is made up of the PS foam reclaimed, pimelinketone, toluene, it is characterized in that: after clearing up classification, cleaning, airing, being broken into fritter, substitute resin of industry by the PS foam reclaimed and make solid constituent; By weight percentage, pimelinketone 28%, toluene 72%, in open metal container when low rate mixing, dissolves PS fragment and becomes thickness gluey to liquid, remove impurity after filtration and be PS tackiness agent.
