Vulcanized thermoplastic rubber vulcanization preparation of the whole dynamic of the successful development of technology

Preparation of high-performance TPV Technology is the key to "dynamic full-curing technology," It is a complex response to the difficult process technology, the world's only U.S. company AES Corporation and the Netherlands, DSM and a small number of companies to master the advanced technology. The study on domestic technology for 20 years, Beijing University of Chemical Technology in 2001 and technology has made a major breakthrough in technology, and 2 years later with the Shandong Dawn Group Co., Ltd. to cooperate in the establishment of the first with independent intellectual property rights Kiloton of high-performance TPV dynamic all-curing technology for industrial production lines.

The main project of this technology: (1) put forward a full pre-dispersion - the whole dynamic vulcanized TPV Technology Preparation methods, the development of high-temperature pre-mixed rubber, with a large number of low-temperature premixed agent, the whole dynamic of high temperature curing process technology to link up the preparation, To achieve a variety of forms of blending components, high-filling blends (in terms of rubber-phase) of the uniform mixture of fine dispersed with rubber vulcanization and the whole dynamic broken, and then realized the industrialization of TPV preparation. (2) put forward for industrial production of TPV twin-screw reactor design parameters, combined with unique blends designed to address the sulfide Dynamic Response refractory, vulcanized rubber and broken the speed of difficult matches and so on, a breakthrough in the dynamics of All-curing technology industrialization of the most crucial technology. (3) the rubber with a broken as the effect of TPV with the important principles of design, and then through the use of special rubber system, curing systems, reinforcing filler system, to soften plasticized system to be realized, the formation of a series of high-performance TPV Special formula. (4) Research Institute found that the use of the continuous phase of the TPV can be plasticized and capacity, the development of low hardness (Shore 38A), high flexibility and high mobility of a new type of TPV Technology.

The project production line has been steadily producing different grades of hardness (Shore 38 A-50D) of ethylene propylene diene monomer (EPDM) / polypropylene (PP) TPV products, the performance of AES Corporation of the United States to achieve the level of similar products. Experts, the technical level to reach the international advanced level.

The production line can be in a production value of 100,000,000 yuan. Has been At present, the production and sale of the TPV products 2150t, the additional output value of 64,000,000 yuan, 26,460,000 yuan of profits to add new revenue 9,600,000 yuan, and exports 350,000 U.S. dollars, the market was well received. The technology filled the gap, breaking the monopoly of international and domestic changes in the demand for TPV totally dependent on imports of the situation, with very significant social and economic benefits.
