Embodiment 1

[0008] Example 1, add 80% of dichloromethane, 3% of dichloroethane, 1% of tetrahydrofuran, and 4% of acetone into the reaction kettle in turn, turn on the stirring blade, control the stirring speed to be about 80r / min, and add to the reaction kettle under stirring. Slowly add 12% polymethyl methacrylate resin (the above are weight percentages) into the kettle, continue to stir until the resin is completely dissolved, stop stirring, and fill.

Embodiment 2

[0009] Example 2, add 84% of dichloromethane, 2% of dichloroethane, 2% of tetrahydrofuran, and 5% of acetone into the reaction kettle in turn, turn on the stirring blade, control the stirring speed to be about 80r / min, and add to the reaction kettle under stirring. Slowly add 7% polymethyl methacrylate resin (the above are weight percentages) into the kettle, continue to stir until the resin is completely 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 on the market, and there are still some disadvantages, such as glue is flammable, and the instant drying effect cannot be achieved when used at low temperature (room temperature is around 5°C), and the product price is high. , the glue is not water resistant and so on. Invention content: [0003] The object of the present invention is to provide a colorless, transparent, water-resistant, low-temperature-resistant, non-combustible, inexpensive and instant-drying adhesive for plastics. [0004] In order to achieve the above object, an instant adhesive for plastics of the present invention is mainly composed of polymethyl methacrylate resin, methylene dichloride, ethylene dichloride, tetrahydrofuran and acetone. The specific proportion is (percentage by weight): 5-15% of polymethyl metha...
