The present situation and Prospect of the unsaturated polyester resin industry in China
China's UPR production, consumption has been ranked first in the world, the production capacity of 2 million tons / year, production of more than 1 million tons / year, the United States in 2004 production of 870 thousand tons. "Fifteen" during the successful development of air dry gel, high toughness gel, UV curing resin and mold coating. The annual output of more than 12 thousand tons of gel coat resin. Compared with the "95" period, the production and sales volume of benzene resin and vinyl ester resin increased 10 times and 5 times, respectively.
The variety of curing agents used in the unsaturated polyester resin and the yield increase very fast. Only MEKP (over oxidation of methyl ethyl ketone) annual production has reached 20 thousand tons. The traditional cyclohexanone peroxide (HCH) production and sales of less than HCH, there are a few liquid market, higher requirements for Piano paint. BPO (benzoyl peroxide), TBPB (TERT butylperoxy benzoate), TBPO[peroxide (2 - Ethyl tert butyl hexanoate)], TBHP (tert butyl peroxide) and other traditional and newly developed initiator, improve production efficiency, and improve the appearance quality of the product.
Accelerator annual sales reached 15 thousand tons. The commonly used cobalt naphthenate (commonly known as "cobalt naphthenate"), cobalt isooctanate accelerator, colorless (containing cobalt naphthenate, containing naphthenic acid potassium containing copper naphthenate, etc.) and other third. Because of naphthenic acid is fatty acid oil fractionation out, due to the nature and the fraction of crude oil, the molecular weight difference with cobalt salt content of its production is difficult to guarantee, so this year the amount decreased, insufficient accelerator sales volume 10%. Cobalt isooctanate stable performance, production and sales of more than 60%. Artificial stone and other products produced using colorless accelerator, the market accounted for about 20% of all sales promoter.
China is rapidly changing to a more sustainable development, and the resin business has been working to promote this change. We are increasing the intensity of investment, the current production capacity continues to upgrade, in order to produce more high-end aquatic products. At the same time, we have also increased our ability to develop the local sustainable paint program development team, in order to achieve from the "made in China" to "China's own design and development" of the strategic transformation. The release of the water based strategic theme of the resin enterprises will show the whole industry that the transformation from the solvent based products to the aquatic products is not as complicated and expensive as many people think. In fact, this change is very simple, because the industry has a corresponding, effective technology."
Last year, the resin enterprises implemented a number of projects to promote the sustainable development of coatings, ym1_tb adhesives and printing ink market. Among them, the most worth mentioning is the combination of the resin industry enterprises to establish an industry leader in the industry - water platform (China) (WBCP). In order to lead the development of water based solutions in public transport and other multiple targeted industry has laid a solid foundation.
The Chinese government is also actively fulfilling its commitment to sustainable development, and has issued a number of policies. The Ministry of environmental protection has over 75% VOC content of nitrocellulose (NC) coating included in the "high pollution, high environmental risk" double high product catalog, and water-borne wood coatings is one of the recommended products to promote environmental protection. State Administration of safety supervision also issued a notice requiring the relevant national enterprises to manage wood furniture manufacturing industry in the presence of high toxic substances hazard problem.
The resin enterprise has laid a solid foundation in the technical aspects of the water coating, and fully prepared to lead the whole industry to accelerate the transformation from the solvent to the water. The introduction of the relevant laws and regulations of the government will make the successful implementation of our water strategy to obtain greater advance power.
