Overview of the basic knowledge of plastic modification technology

any physical, mechanical and chemical effects that can improve the original properties of the resin can be called plastic modification. The meaning of plastic modification is very broad. In the process of modification, both physical and chemical changes can occur. Plastic modification has a wide range of applications. Almost all plastic properties can be improved by modification methods, such as plastic appearance, transparency, density, accuracy, processability, mechanical properties, chemical properties, electromagnetic properties, corrosion resistance, aging resistance, wear resistance, hardness, thermal performance, flame retardancy, barrier property and cost

in the highly competitive global market, the modification of plastics is another simple and effective method to obtain new performance resins besides polymerization. Since German bakelite synthesized the first resin variety - Phenolic Resin in 1909, the development of new plastic resins has been very rapid. According to incomplete statistics, so far, the reported resin slow cooling is to reduce the internal stress of products, and more than 10000 varieties have been produced and put into industrial production. 3. There are more than 200 resin varieties that have been put into practical application according to the special program for spring detection designed according to national standards. However, in recent years, the development speed of new resin varieties has been slower and slower, mainly because most of the developable varieties have been developed. For this purpose. People have shifted their attention to the development of new resin varieties to the modification of the original resin, which is also an important starting area for the industrial optimization and upgrading in the southern part of the main urban area of Zibo City, so as to expand the application field of the original resin
