At present, the production of c9 petroleum resin in China is low and its quality is poor, which limits its application. Therefore, China's c resources are not fully utilized.
Now, the price of c9 petroleum resin by rising, showing a trend of increasing year by year.
China c9 petroleum resin brand is not many, the color is darker, no unified quality index, the application is not yet widespread.
Such as the paint industry, the current production of industrial coatings 4.1772 million tons, the need for resin 1.25 million tons, if the petroleum resin added amount of 10%, it needs more than 125,000 tons.
But domestic light color resin products are less, which affects the application in high-grade paint.
Because color is deeper, solubility is poor, have a few small paint factory to use only, a few large and medium-sized paint factory are used at low grade paint production only, also have a few applications in the adhesive of factory of additive of tire, low grade ink, rubber shoe additionally.
If the introduction of polar groups, copolymerization, hydrorefining and other measures to improve product quality, c9 petroleum resin will have a larger market.
C9 petroleum resin has good thermal stability, good weather resistance, wide compatibility, can be applied to styrene type of block polymer (SBC) hot melt pressure sensitive adhesive, ethylene/vinyl acetate copolymer (EVA) is a hot melt adhesive, pressure sensitive resistance since the glue adhesives, polypropylene film modifier, and other products, also can be used as a rubber tackifier and strengthening agent, drying oil modification agent, sizing agent of paper, ink color agent and connection.
The emulsion of C9 petroleum resin emulsified by solvent and emulsifier can be mixed with neoprene emulsion to make exterior wall coating with strong adhesion and weather resistance, and anti-rust coating.
Mixing with emulsified asphalt can make waterproof coating.
Used as casting adhesive, can improve the yield of casting.
C9 petroleum resin manufacturers want to achieve significant development, comprehensive utilization is the key.
C9 is mainly used to produce petroleum resin.
In the paper industry, C9 petroleum resin as a substitute of rosin resin has been more and more concerned by the market.
In the printing ink industry, C9 petroleum resin was used to replace the calcium base rosin in the original formula, which also achieved good results.
In addition, the coatings industry, a major user of petroleum resins, USES about half of its C9 petroleum resin production per year.
At the meeting, it was learned that the increase of ethylene production in China has provided support for the expansion of the market of carbon pentax and C9 petroleum resin.
In 2010, China's inland pyrolysis ethylene production capacity was 15 million tons and production capacity was 13.8 million tons, and production of carbon 5, a by-product, was 180 tons and production of carbon 9 was 1.4 million tons.
With the development of ethylene industry, the total amount of carbon 5 will exceed 2.6 million tons and carbon 9 will exceed 2 million tons by 2015.
Dicyclopentadiene in c9 petroleum resin is mainly used in the production of medicine, pesticides, resin products;
Methyl dicyclopentadiene is mainly used as raw material for the production of high-energy rocket fuel, plasticizer and curing agent.
And the price of methyl cyclopentadiene is as high as 20,000 tons, which makes it very profitable.
It is concluded that the comprehensive utilization of c9 petroleum resin has a broad prospect, and if the resources of c9 can be reasonably developed and utilized, greater economic benefits will be obtained.
With the development of China's economy, the demand for c9 petroleum resin will continue to increase, China's c9 petroleum resin is mainly used in coatings, adhesives, rubber additives, ink and other industries.
Petroleum resin is mainly used as rubber softener (or additive) in the rubber industry.
The raw material of gumaron resin comes from coking industry, which cannot meet the demand of rubber industry.
C petroleum resin can be used as the quality improver and functional additive of styrene-butadiene rubber. Styrene-butadiene rubber lacks viscosity and is hard, while c petroleum resin has the function of dividing styrene-butadiene rubber molecules, making it produce better bond performance.
Rubber, thickener, softener and c9 petroleum resin, solvent compound adhesive can be used in adhesive tape products.
The analysis and comprehensive utilization of resources by c9 petroleum resin manufacturers will certainly bring more benefits. We must pay attention to this information.
