AI Technical Summary

Problems solved by technology

Neoprene rubber can be formulated into neoprene rubber adhesives after being dissolved in a solvent, but the performance is poor. Therefore, various neoprene rubber adhesives commonly used are based on neoprene rubber, and various compounding agents are added, such as resins, vulcanizing agents, Accelerators, fillers, etc. to improve the performance of adhesives

Embodiment

[0006] 1. Put 20 parts of neoprene rubber into a container, raise the temperature to above 140°C to make the neoprene rubber into a molten state, add 1 part of zinc oxide and 1 part of magnesium oxide and stir well, react for 1 hour and then cool.

[0007] 2. Mix the above-mentioned cooled solid with 50 parts of styrene in a container until the neoprene rubber is completely dissolved, add 3 parts of polyisocyanate, 3 parts of polyester resin, and 2 parts of vinyltrisilane, and stir for 1 hour to react evenly.

[0008] 3. Add 2 parts of anti-aging agent D and 18 parts of silicon dioxide to the above reaction solution, continue to stir for 20 minutes to obtain the finished product and pack it.

Abstract

The invention discloses a production method for a chloroprene rubber adhesive. The product produced by the production method is a high-performance adhesive. The adhesive is produced by using chloroprene rubber as a main body and using raw materials including styrene, silicon dioxide, magnesium oxide, zinc oxide, polyisocyanates, polyester resin, vinyl trisilane, antiaging agent D and the like and by a certain process. The product is mainly used in the building industry for adhering ethylene propylene diene monomer rubber waterproof coiled material, chlorinated polyethylene-rubber blended waterproof coiled material, chlorinated polyethylene waterproof coiled material, sulfurized rubber plastic waterproof coiled material, chlorinated polyethylene plastic floorings and calcium plastic plates with concrete, cement, asbestos boards, wood and other materials.

Description

Technical field: [0001] The product of the present invention belongs to the field of chemical industry Background technique: [0002] Adhesives made of neoprene as the main material are called neoprene adhesives. Neoprene rubber can be formulated into neoprene rubber adhesives after being dissolved in a solvent, but the performance is poor. Therefore, various neoprene rubber adhesives commonly used are based on neoprene rubber, and various compounding agents are added, such as resins, vulcanizing agents, Accelerators, fillers, etc. to improve the performance of the adhesive. Like natural rubber, chloroprene rubber can be vulcanized by adding a vulcanization system to make its chain structure form a network or body structure, and its strength is strengthened. The most commonly used vulcanizing agents for neoprene are magnesium oxide and zinc oxide. Generally speaking, this vulcanization system is vulcanized at a high temperature of 140°C, but in fact, magnesia and zinc oxi...
