Development History And Application Status Of Terpene Resin In China

- Dec 27, 2019-

In 1789, it was discovered that turpentine was polymerized into resin under the action of H2SO4, which revealed the first case of cationic polymerization theory. In 1933, it was successively discovered that isobutylene acted on BF3 for cationic polymerization. From 1937 to 1944, butyl rubber was industrialized and cationic polymerization theory was gradually established.

Due to the limitation of analytical methods and extraction methods at that time, the production scale was small, so the terpene resin synthesis process of turpentine was not valued and developed.

In 1930, synthetic terpene resin was first industrialized in the United States, and then in the United States, Japan, France, Britain, the Soviet union, Mexico and other countries.

By the end of the 20th century, the world's terpene resin production had reached 50,000 tons, including 15,000-20,000 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 terpene resin manufacturers in Western Europe include: German LG dyestuff industry company, French E.S.S.D company, British BX plastics company and so on.

After the founding of the People's Republic of China, China's forest product industry has developed rapidly, and the output of turpentine, especially turpentine, has become the first in the world. The research on the deep processing and utilization of turpentine in China and the product development have made great progress, driving the development of terpene resin.

The development of terpene resin in China began in the late 1960s, and it was successively put into production in Shanghai no.3 spice factory, guangdong xinyi forest chemical factory and fengkai forest chemical factory, and fujian taining forest chemical factory.

In the 1980s, domestic production was less than 2,000 tons.

In order to develop the terpene resin industry in sichuan province and make full use of the turpentine resources in sichuan province, in 1984, the research office of forest products and chemical engineering of sichuan academy of forestry began to use yunnan turpentine oil to produce terpene resin with light color and high softening point.

In order to expand the production scale of terpene resin and meet the needs of domestic and foreign markets, a terpene resin workshop was set up in yanyuan rosin factory in 1988, and the terpene resin was further processed with turpentine produced by the factory itself.

On May 26, 1990, the official trial production, and a successful trial production, fully reached the design capacity of 200 tons/year.

From sichuan forest products quality inspection and product quality of forestry chemical products quality supervision and inspection sampling inspection, product quality is superior to the national industry standard LY/T1453-1999 the terpene resin (the standard number of ZBB72007-88), part of the product quality has reached the standard Hector zeigler, companies in the United States and Japan AnYuan grease chemical co., LTD enterprise standard, due to the shallow color products, high softening point, also is the 1990 Beijing Asian games to choose playground line paint [5].

Some research institutes, such as the institute of forest products and chemical engineering of caf and the fujian provincial institute of chemical industry science and technology, have also made research breakthroughs, designing and constructing a batch of batch operation devices with a production capacity of 500 tons/year (equipment specifications are basically standardized).

Pressure sensitive adhesive tape, hot melt coating, rubber adhesives, glazed light color ink, ink water resistance and chemical resistance, chewing gum and cable industries of terpene resin is widely used and the growing demand, desire perfumery plant in fujian, jiangxi MaShan chemical co., LTD., ganzhou Thai PuHua company, Jiang Xijing gen resin co., LTD., guangdong deqing forest chemical factory, jiangxi news resin factory, etc., are all from above research achievements of forest chemical research institutes, established their own devices, processing capacity of 200 ~ 500 tons/year, USES the polymerizer concentration and washing, distillation hydrolysis in the intermittent operation mode.

Although they have continuously summarized their experiences and made many improvements in production, they are still unable to get rid of the limitations of intermittent operation and small-scale operation.
