Problems solved by technology

[0002] At present, most of the road marking paints used in the market have relatively poor weather resistance. If they are too cold or too hot, they will change color and fall off, etc.; the service life is as little as three months, and as long as half a year, the road marking paint needs to be replaced once, which greatly increases labor and materials. cost

Embodiment Construction

[0016] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0017] A method for improving the performance of petroleum resin products, see figure 1 ,

[0018] 1) Using pentane as a solvent, aluminum trichloride as a catalyst, and monoolefin and piperylene as raw materials, carry out cationic polymerization in a C5 separation device to obtain a polymerization liquid;

[0019] 2) After reducing washing and washing with water, the catalyst is deactivated, and the catalyst and other impurities are removed;

[0020] 3) Then remove the pentane solvent and oligomers by normal and vacuum stripping;

[0021] 4) Add a modifier before entering the granulation package, the modifier is polyisobutylene maleic anhydride, and the amount o...

Abstract

The invention discloses a method for improving the performance of a petroleum resin product. The method comprises the steps of performing cationic polymerization to obtain a polymerization solution by using pentane as a solvent, aluminium trichloride as a solvent and monoolefine and piperylene as raw materials; performing alkali washing and water washing to inactivate the catalyst and remove the catalyst and other impurities; then performing normal and reduced pressure steam stripping to remove the pentane solvent and oligomers; and adding a modifier, then granulating and packaging, wherein the modifier is polyisobutene maleic anhydride. By adopting the method for improving the performance of the petroleum resin product, the weather tolerance, pollution resistance, levelling property, adhesion and the like of the product obtained by adding the maleic anhydride modifier in the process of serving as a hot-melt traffic coating are better than those of a traffic coating without the modifier.

Description

technical field [0001] The invention relates to a method for improving the performance of petroleum resin products. Background technique [0002] At present, most of the road marking paints used in the market have poor weather resistance. If they are too cold or too hot, they will change color and fall off. cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome existing defects and provide a method for improving the performance of petroleum resin products that can effectively improve the weather resistance, stain resistance, leveling and adhesion of petroleum resin products. [0004] The purpose of the present invention is specifically achieved through the following technical solutions: [0005] A method for improving the performance of petroleum resin products, [0006] 1) Using pentane as a solvent, aluminum trichloride as a catalyst, and monoolefin and piperylene as raw materials, carry out cationic polymer...
