Embodiment 1

[0008] In Example 1, 80% of dichloromethane, 3% of dichloroethane, 1% of tetrahydrofuran, and 4% of acetone were added to the reaction kettle in sequence, the stirring blade was turned on, and the stirring speed was controlled to about 80r / min. Slowly add 12% of polymethyl methacrylate resin (the above are weight percentages) into the kettle, continue to stir until all the resin is dissolved, stop stirring, and fill.

Embodiment 2

[0009] In Example 2, 84% of dichloromethane, 2% of dichloroethane, 2% of tetrahydrofuran, and 5% of acetone were added to the reaction kettle in turn, the stirring blade was turned on, and the stirring speed was controlled to about 80r / min. Slowly add 7% of polymethyl methacrylate resin (the above are weight percentages) into the kettle, continue to stir until all the resin is dissolved, stop stirring, and fill.

Abstract

The present invention discloses a rapidest adhesive for plastics. It is mainly formed from polymethyl methacrylate resin, dichloromethane, dichloroethane, tetrahydrofuran and acetone. It can be extensively used for instantaneous adhesion bond between plastic self-bodies or mutually them or ABS plastics, PS plastics, HIPS plastics, PMMA plastics, PVC plastics, PC plastics, polysulfones plastics, polyphenyl ether, acetyl cellulose and cellulose propionate. Said adhesive is colourless and trasparent, water-proof, fire-retardant, and is good in low-temp. adhesivity.

Description

Technical field [0001] The invention relates to an instant-drying adhesive for plastics. Background technique [0002] At present, there are very few types of instant adhesives for plastics used in the market, and there are still some disadvantages, such as the glue is flammable, and cannot achieve instant drying effects when used under low temperature conditions (the room temperature is about 5°C), and the product price is high. , The glue is not water resistant and so on. Summary of the invention: [0003] The purpose of the present invention is to provide an adhesive for plastics that is colorless, transparent, water-resistant, low-temperature resistant, non-combustible, low-cost, and instant-drying. [0004] In order to achieve the above objective, the instant adhesive for plastics of the present invention is mainly composed of polymethyl methacrylate resin, dichloromethane, dichloroethane, tetrahydrofuran and acetone. The specific ratio is (weight percentage): polymethyl me...
