Abstract

The invention discloses a plastic adhesive. The adhesive is prepared in steps as follows: a, asphalt and n-heptane are mixed, treated in an airtight reaction kettle at the temperature of 100-150 DEG C for 1-12 h and filtered, and filtrate is obtained; b, the filtrate is dried in the nitrogen fluid state at the temperature of 100-150 DEG C for 1-10 h, solids are obtained, finely ground, sieved by a 50-120-mesh sieve and then dispersed in ethyl alpha cyanoacrylate to be stirred for 10-30 min, ethyl carbamate glycol, 2,4,4-trimethyl-1,6-hexamethylene diamine, ethylene carbonate, dichloro-hexylidene diisocyanate, melamino-formaldehyde resin, epoxy resin, vinyl chloride-vinyl acetate resin, an expanding agent, desulfurized gypsum and a curing agent are added, and the plastic adhesive is obtained. The provided plastic adhesive can powerfully bond a wood material and plastic, and no harmful organic substances are produced.

Description

Technical field [0001] The invention relates to the technical field of adhesives, in particular to a plastic adhesive. Background technique [0002] Adhesives are used to connect the same or two or more homogenous or heterogeneous parts (or materials) together, and are organic or inorganic, natural or synthetic substances with sufficient strength after curing. [0003] Chinese patent CN1664042A discloses a modified waste polystyrene foam adhesive, which is to mix the cyclohexene solution of the waste polystyrene foam with the ethyl acetate solution of SBS, and stir it evenly. Add the rosin, stir well until it is completely dissolved, add the emulsifier sodium dodecylbenzene sulfonate and OP-10 according to the proportion, mix and stir evenly; then according to the proportion of plasticizer dibutyl phthalate, mix and stir evenly, Instant adhesive. Since the choice of raw material is waste polystyrene foam, the cyclohexene used is a low-toxic, inexpensive industrial-grade solvent,...
