Problems solved by technology

The structure of chloroprene rubber is relatively regular, and there are chlorine atoms with high polarity, so it has high crystallinity. It has good bonding performance and high cohesive strength at room temperature, and is very suitable as an adhesive. The characteristics of neoprene adhesive are: large initial adhesion, high bonding strength, good durability, flexible adhesive layer, good elasticity, impact and vibration resistance, good oil resistance, water resistance, alkali resistance, acid resistance and solvent resistance. , has good adhesion to a variety of materials, easy to use, low price, but poor heat resistance, poor water resistance, poor storage stability, high toxicity and other shortcomings, and it is easy to lose viscosity when exposed to the external environment for a long time , leading to a greatly shortened service life, and the limitations of its heat resistance, its application has been greatly restricted

Description

technical field [0001] The invention belongs to the technical field of rubber adhesive preparation, and in particular relates to a heat-resistant rubber adhesive and a preparation method thereof. Background technique [0002] Adhesive refers to a class of natural or synthetic, organic or inorganic substances that can connect two or more parts or materials together through interface adhesion and cohesion. Among them, neoprene adhesive is also known as "universal glue" and occupies an important position in the application. Neoprene is the main raw material of neoprene adhesive. The adhesive can be cold-cured at room temperature, has a large initial adhesion, rapid strength build-up, high bonding strength, excellent comprehensive performance, and is extremely versatile. It can bond rubber , leather, fabric, leather, plastic, wood, paper, glass, ceramics, concrete, metal and other materials. [0003] Neoprene is a synthetic rubber compound that is produced in large quantities ...
