Problems solved by technology

Most of the existing traffic marking materials are made of petroleum resin and modified rosin resin mixed with stone powder. However, this traffic marking material is easy to crack and peel off under low temperature and severe cold weather conditions, resulting in blurred markings , the visual effect is not strong, which increases the risk of traffic accidents, especially for environments with strict traffic marking requirements such as expressways and airport roads, which cannot meet its use requirements

Abstract

The invention provides an anti-freezing low-temperature-resisting traffic marking material and a preparation method thereof. The traffic marking material comprises the following components in parts by weight: 10-18 parts of polyester resin, 10-18 parts of rosin glycerol ester, 5-15 parts of polytetrafluoroethylene, 8-14 parts of poly(p-xylylene), 6-10 parts of modified polypropylene, 4-5 parts of quartz powder, 4-5 parts of glass bead, 1-3 parts of tung oil and 20-30 parts of ethylene glycol ether. The traffic marking material provided by the invention has excellent low temperature resistance, anti-cracking property and freeze thawing stability, can stand the test under frost weather and sudden cold and heat extreme weather and can keep excellent weather fastness.

Description

technical field [0001] The invention relates to the technical field of traffic, in particular to an antifreeze and low temperature resistant traffic marking material and a preparation method thereof. Background technique [0002] Traffic markings are traffic safety facilities composed of various lines, arrows, characters, facade marks, raised road signs and contour marks marked on the road surface. Its function is to control and guide traffic. [0003] Traffic markings coated on traffic roads are not only subject to the rolling and wear of wheels, but also the erosion of wind, sun and rain. In the cold north, they even have to withstand the test of extreme cold weather. Most of the existing traffic marking materials are made of petroleum resin and modified rosin resin mixed with stone powder. However, this traffic marking material is easy to crack and peel off under low temperature and severe cold weather conditions, resulting in blurred markings. , the visual effect is not...
