Problems solved by technology

[0002] During off-road driving, ice and snow weather is difficult to predict. In most cases, drivers cannot know the state of the road surface under low temperature conditions in winter. The driving environment is harsh when the road surface is icy, which is likely to cause traffic accidents. Early warning is particularly important
At present, my country hangs traffic signs to indicate road conditions under bad weather conditions, but the current traffic sign shell is poor in waterproof, and its aging resistance cannot meet the demand

Abstract

The invention discloses a waterproof material used for a traffic signs housing. The waterproof material comprises the following components in parts by weight: 20-30 parts of a nitrile silicone rubber, 40-60 parts of composite alkene, 20-30 parts of a styrene butadiene rubber, 1-2 parts of vinyltrimethoxy silane, 85-95 parts of a filling strengthening agent, 0.1-0.4 parts of sodium dichromate, 4-8 parts of dicumyl peroxide, 3-5 parts of a plasticizer, 2-4 parts of tricresyl phosphate(hexadecenol)ester, 2-4 parts of liquid coumarone resin, 1-2 parts of tridecyl phosphate, 1.5-2.5 parts of an ultraviolet light absorbent UV-531, and 2-4 parts of acetylacetone titanium. The material has the advantages of good toughness and hardness, good sealing performance, excellent cold resistance and water resistance, and good aging resistance under extreme environment.

Description

technical field [0001] The invention relates to the technical field of traffic signage, in particular to a material for a waterproof traffic sign shell. Background technique [0002] During off-road driving, ice and snow weather is difficult to predict. In most cases, drivers cannot know the state of the road surface under low temperature conditions in winter. The driving environment is harsh when the road surface is icy, which is likely to cause traffic accidents. Early warning is particularly important. At present, my country hangs traffic signs to indicate road conditions under bad weather conditions, but the current traffic sign shell is poor in water resistance, and its aging resistance cannot meet the demand. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a waterproof traffic sign shell material, which has good toughness and hardness, excellent sealing performance, excellent co...
