At present, foreign road marking paints are highly water-based and develop rapidly. More than 90% of road marking paints in developed countries such as the United States, Germany, Spain, Sweden, and Finland use water-based products. Due to the early start of foreign road marking coatings and the rapid development of technology, nanometer road marking coatings, two-component road marking coatings, pigment-coated road marking coatings, and so on have appeared.
Rosin glycerol resin is the product of esterification of rosin with glycerol. It’s a transparentirregular solid after vacuum treatment.
Part One:Our High purity Calcium Metal Production Line Generally Annual Out Put is about 1500 ton per year and the purity can be reach to 99.99%
Ethylene cracking C5 fraction atmospheric pressure rectification intercepts 45-75℃ isoprene enriched component as raw material A; ethylene cracking C5 fraction atmospheric pressure rectification intercepts 25-45℃ isoprene enriched component as raw material B ; Ethylene cracking C9 fraction is vacuum rectified under 0.08～0.095MPa,Petroleum Resin and the fraction with boiling point of 140～180℃ is taken as the raw material C. The above three raw materials A, B and C are prepared according to the mass ratio of 1:1.5～3.0:1.5～3.0 C5/C9 petroleum resin polymerization raw material D;
C5 petroleum resin is converted into C5 hydrogenated petroleum resin by hydrogenation under palladium bimetallic catalyst. The catalyst contains alumina-titania composite carrier and metal palladium and metal molybdenum or metal tungsten supported on the composite carrier;Petroleum Resin The content is 0.2-0.4% based on the weight of the catalyst;
With the rapid development of the national economy,Petroleum Resin especially the rapid development of three barrels of oil, such as Sinopec, ethylene capacity has gradually increased,Petroleum Resin and more and more C9 is cracked. How to use this part of resources to develop downstream products is increasingly causing People's attention.
