Description

technical field [0001] The invention relates to a glue composition, in particular to a special glue for plastics. Background technique [0002] Plastic is a kind of synthetic polymer material with plasticity. It, synthetic rubber and synthetic fiber form the three major synthetic materials that are indispensable in today's daily life. Specifically, plastic is a material with natural or synthetic resin as the main component, adding various additives, which can be molded into a certain shape under certain conditions such as temperature and pressure, and maintains the same shape at room temperature. The types of commonly used plastics are: PPT plastic, ABS plastic, PVC, PE and PP, etc. Plastic products have light weight, excellent chemical stability, excellent electrical insulation performance, are poor conductors of heat, and have the effect of noise reduction and shock absorption. It has many advantages such as wide distribution of mechanical strength and high specific stren...

Problems solved by technology

[0003] Although plastic products have so many benefits and are widely used, they will break or be damaged after being used for a long time or because of improper use. Because there is no glue specially used for sticking plastic products in the prior art, people will Use some general glues on the market to stick plastic products, but the effect is often not ideal, and finally the damaged plastic products have to be thrown away. This method is not only a waste of money, but also not conducive to environmental protection. Plastic waste pollutes the environment and has become A difficult problem of environmental pollution, known as "white pollution"

If there is a glue specially used for sticking plastic products, then a large number of plastic products will be repaired and utilized without being thrown away, saving a lot of money, and at the same time solving the problem of plastic products polluting the environment. How to provide a Special glue for plastics has become an urgent need for people
