The petroleum resin is a pale yellow thermoplastic resin, and its properties are related to the composition of the olefin in the raw material. General physical and chemical properties of petroleum resin is: hue is less than 13, softening point 40~140 ℃, acid value is less than 0.1, base value is less than 4, bromine value is 7~50, iodine value is 30~140, ash content is less than 0.9%, the relative density of 0.97~1. 07, molecular weight 440~3000, refractive index 1.512, ignition point 260. Dissolved in Ketones, Esters, halogenated hydrocarbons and petroleum-based solvents. Good compatibility with other resins such as alkyd resin, phenolic resin, polystyrene and cumarone resin. The dielectric constant is 2. 33 (108Hz) and the dielectric loss tangent is 0.0008 (108 H2).
The cracking oil obtained from the cracking of petroleum to produce olefins is separated into 130~160 ℃ fractions (containing styrene, methyl styrene, divinylbenzene and indene, etc.), the thermoplastic resin obtained by polymerizing in the presence of an acidic catalyst and Friedel-Crafts, boron trifluoride, sulfuric acid, etc.; Or copolymerizing its fraction with aldehydes, aromatic hydrocarbons, terpenes, collectively known as petroleum resins. In general, after the completion of the polymerization reaction, the final product is obtained by removing the catalyst, washing, separation and other processes.
petroleum resins are mainly used in the coating industry, such as petroleum resin emulsions as reinforcing synthetic latex coatings; Light-colored petroleum resins are used in the manufacture of oily varnishes to improve gloss and adhesion. A resin having a low softening point is used as a plasticizer for rubber; A resin having a high softening point is used to increase the hardness of a synthetic rubber. It is also used for hot-melt coating of paper to make water-resistant corrugated paper, etc. It and chlorinated paraffins and surfactants can be composed of architectural coatings. It is also widely used in printing inks and adhesives.
Product packaging for insulating film bags, outer packaging for polypropylene woven bags, each bag net weight 25kg, net weight error of ± 0.2%. It can be stored in a clean and dry warehouse for a long time, and should be away from the fire source and heat source. Non-dangerous goods can be transported, transport tools should be kept clean and dry, no nails and other sharp objects, to be equipped with tarpaulin. It is strictly prohibited to use iron hooks for loading and unloading.

source | petroleum resin is named after the source of petroleum derivatives. it has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance, chemical stability to acid and alkali, and good viscosity and thermal stability. Petroleum resins are generally not used alone, but are used together as accelerators, regulators, modifiers and other resins. |
application | hot melt adhesive other applications: hot melt pressure sensitive adhesive, solvent-based pressure sensitive adhesive. performance and function of petroleum resin in different industries: a, paint paint mainly uses C9 petroleum resin with high softening point, DCPD resin and C5/C9 copolymer resin. adding petroleum resin to paint can increase paint gloss and improve paint film adhesion, hardness, acid resistance and alkali resistance. B, rubber rubber mainly uses C5 petroleum resin, C5/C9 copolymer resin and DCPD resin with low softening point. This kind of resin and natural rubber rubber particles have good mutual solubility and have no great influence on the rubber vulcanization process. Adding petroleum resin to rubber can play the role of increasing viscosity, strengthening and softening. In particular, the addition of C5/C9 copolymer resin can not only increase the adhesion between the rubber particles, but also improve the adhesion between the rubber particles and the cord, and is suitable for rubber products with high requirements such as radial tires. C. Adhesive Industry Petroleum resin has good adhesion. Adding petroleum resin to adhesive and pressure-sensitive adhesive tape can improve adhesive force, acid resistance, alkali resistance and water resistance of adhesive, and can effectively reduce production cost. D, ink industry petroleum resin for ink, mainly C9 petroleum resin with high softening point and DCPD resin. Adding petroleum resin to ink can play the effect of color development, quick drying, brightening, and improve printing performance. e, coating industry road signs and road marking coatings, petroleum resin has good adhesion to concrete or asphalt pavement, and has good wear resistance and water resistance, and has good affinity with inorganic substances, easy coating, good weather resistance, fast drying, high firmness, and can improve the physical and chemical properties of the layer, improve ultraviolet resistance and weather resistance. At present, petroleum resin road marking paint is gradually becoming mainstream, and the demand is increasing year by year. F, other resins have certain unsaturated properties and can be used for paper glue, plastic modifier, etc. 5. petroleum resin is non-dangerous goods. during transportation, sun and rain should be prevented. Do not transport with spontaneous combustion, strong oxidant and strong acid. petroleum resin should be stored in a ventilated, cool and dry environment. The storage period is generally one year, and it can still be used after one year if it passes the inspection. |
