The development history of terpene resin in China and its application status

- Nov 25, 2019-

In 1789, it was found that turpentine was polymerized and converted into resin under the action of H2SO4. The first example of cationic polymerization theory was unveiled. In 1933, the role of isobutylene in BF3 was found to be cationic polymerization. From 1937 to 1944, butyl rubber was industrialized. Gradually create the theory of cationic polymerization. Due to the limitations of analytical methods and extraction methods at the time, the scale of production was small, and the process of synthesizing terpene resin from turpentine was not taken seriously. In 1930, the synthetic terpene resin was first industrialized in the United States, and successively realized industrial production in the United States, Japan, France, Britain, the Soviet Union, Mexico and other countries. At the end of the 20th century, the world's terpene resin production reached 50,000 tons, including 1.5-2 million tons in the United States, 15,000 tons in Japan, and more than 2,000 tons in the Soviet Union. In 1994, the consumption of terpene resin in Western Europe exceeded 20,000 tons. The famous manufacturers of terpene resins in Western Europe include: LG Dyestuff Industry of Germany, E.S.S.D. of France, and BX Plastics of the United Kingdom.

    After the founding of the country, the forestry industry developed rapidly. The production of turpentine oil, especially turpentine, ranked first in the world. The research and product development of turpentine in China has made great progress and promoted the development of terpene resin. Since the end of the 1960s, the domestic terpene resin has been put into production at Shanghai Spice Factory No. 3, Guangdong Xinyi Forest Chemical Plant and Fengkai Forest Chemical Plant, and Fujian Taining Forest Chemical Plant. Domestic production in the 1980s was less than 2,000 tons. In order to develop the terpene resin industry in Sichuan Province, Sichuan Province made full use of the turpentine resources in Sichuan. In 1984, the Forestry Science and Chemical Research Laboratory of the Sichuan Academy of Forestry began to use Yunnan turpentine oil to produce light-colored high-softening point terpene resin. In 1986, in the Yibinlin Chemical Plant The test was successful, and the test product won the title of provincial excellent product in 1987. In order to expand the production scale of terpene resin and meet the needs of domestic and foreign markets, in 1988, a terpene resin workshop was established in the Yanyuan Rosin Plant, and the terpene resin was further processed using the turpentine produced in the factory. It was officially trial-produced on May 26, 1990, and a trial production was successful, reaching a design capacity of 200 tons/year. The product quality has been tested by the Sichuan Provincial Forest Product Quality Inspection Station and the Forestry Chemical Quality Supervision and Inspection Station of the Ministry of Forestry. The product quality is superior to the national industry standard LY/T1453—1999 “Tenene Resin” (the standard number at the time was ZBB72007- 88) The requirements of some products have reached the standards of the American Hegels Company and the Japanese Anyuan Oil and Fat Chemical Co., Ltd. Due to the light color and softening point of the product, it was also selected by the Beijing Asian Games in 1990 for the sports field road markings. Paint [5]. Some research units such as the Institute of Forest Products and Chemical Engineering of the Chinese Academy of Forestry and the Institute of Chemical Industry and Technology of Fujian Province have also made research breakthroughs, and designed and built a batch of intermittent operation devices with a production capacity of 500 tons/year (basic finalization of equipment specifications). .

    Pressure-sensitive adhesive tape, hot melt coating, rubber adhesive, high gloss light ink, water and chemical resistant ink, chewing gum and cable industry, widely used and expanding demand for terpene resin, Fujian Qingliu Perfumery Jiangxi Mashan Chemical Co., Ltd., Zhangzhou Taipu Chemical Co., Jiangxi Jingchuang Resin Co., Ltd., Guangdong Deqing Forest Chemicals General Factory, Jiangxi Jishui County Resin Factory, etc., all inherit the research results of the above-mentioned forestry chemical research institutes, and successively established The self-installation device has a processing capacity of 200 to 500 tons/year, and is a batch operation method in which polymerization polymerization is carried out, hydrolysis washing, and distillation are carried out. Although each family has continuously summed up experience in production and made many improvements, it is still difficult to get rid of intermittent operations and small-scale restrictions.
