Advantages of Gao Qiao's patent application

Chenmei pigment masterbatch provides a solution for ABS. ABS resin is the most typical multi-phase and multi-component polymer material, and it is a kind of general plastic with a wide variety and excellent comprehensive performance, which is widely used in automobile industry, household appliances and other fields. The development of ABS resin in China began in 1960s. The rubber factory of Lanzhou Chemical Company started the experiment on 1963. 1970 completed the first ABS resin production plant in China, and 1975 was put into operation with a production capacity of 2,000 t/a; 1974, Shanghai Gao Qiao Chemical Plant also built a set of equipment for producing ABS resin by suspension method with a production capacity of 3,000 t/a. Compared with foreign countries, two sets of equipment developed in China are not perfect, and neither of the above two processes can synthesize large-particle latex in one step, so it needs to be enlarged and then grafted, which adds trouble to the operation. Some processes are not matched, the level of automation is low, and it is difficult to further improve the quality; In addition, due to the lack of varieties and brands, the application scope is very narrow. All these restrict the production and application of ABS resin in China.

In order to speed up the production of ABS resin in China, the synthetic rubber factory of Lanzhou Chemical Industry Company introduced a set of production equipment with the scale of 10000 t/a from Mitsubishi Rayon Company of Japan in 1982, and technically adopted emulsion grafting-suspension method as the blending process. 1983, Shanghai Gao Qiao chemical plant purchased a set of idle ABS resin production equipment from USS, with a production capacity of 22,500 t/a, and adopted emulsion grafting-emulsion as blending production technology; At the end of 1986, the organic synthesis unit of Jihua Company signed a contract with Japan Toyo Engineering Company-Mitsui East Asia Company (TEC-MTC) to introduce a set of 1 10,000 t/a continuous bulk method to produce ABS resin (now used to produce high impact polystyrene); After 1990, several sets of ABS equipment were put into production in China. At present, there are six ABS manufacturers in Chinese mainland, namely Jihua (654.38+100000 t/a), Daqing (50000 t/a), Lanhua (20000 t/a), Panjin (50000 t/a), Zhenjiang Guo Heng (50000 t/a) and Zhejiang Nanxing (50000 t).

China is the largest consumer of ABS resin in the world. In recent years, the annual consumption of ABS resin has exceeded 120t. 1999 China's ABS output is about150,000 t/a, and its import volume is133,000 t. It imported 950,000 t from June to September in 2000, which has great market potential. At present, the self-sufficiency rate of ABS in China is very low, and a large number of imported products are needed to meet the demand. Other countries and regions in the world are dumping products at me. The joint venture production plant in Chinese mainland plans to expand its production capacity and form a supply base. For example, LG Korea plans to increase the capacity of Yongxing ABS plant to 300,000 t/a in 200 1 year. At the same time, ABS manufacturers all over the world have applied for patents in China to strengthen and expand their influence and share in the China market.
