Embodiment 1

[0013] The present invention proposes a rubber material for an anti-aging traffic sign shell, and its raw materials include by weight: 50 parts of polypropylene compound, 60 parts of neoprene rubber, 30 parts of thermoplastic polyurethane elastomer, 16 parts of mica sheet, zeolite powder 12 parts, 18 parts of expanded perlite, 50 parts of precipitated barium sulfate, 4 parts of crosslinking agent, 2 parts of calcium stearate, 4 parts of disproportionated rosin, 1.5 parts of 4-cinnamon phenol, 2,2'-methylene bis( 4-methyl-6-tert-butylphenol) 2 parts, plasticizer 7 parts, lubricant 7 parts.

Embodiment 2

[0015] The present invention proposes a rubber material for an aging-resistant traffic sign shell, and its raw materials include, by weight, 70 parts of polypropylene compound, 40 parts of neoprene, 50 parts of thermoplastic polyurethane elastomer, 10 parts of mica flakes, and zeolite powder 15 parts, 10 parts of expanded perlite, 60 parts of precipitated barium sulfate, 3 parts of crosslinking agent, 4 parts of calcium stearate, 2 parts of disproportionated rosin, 2.5 parts of 4-cinnamon phenol, 2,2'-methylene bis( 4-methyl-6-tert-butylphenol) 1 part, plasticizer 10 parts, lubricant 5 parts.

[0016] The polypropylene composite is prepared by the following process: immerse carbon fiber in ethanol dilution of 1-hexyl-3-methylimidazolium tetrafluoroborate, filter, dry, heat up, keep warm, add polypropylene, calcined medical stone , silane coupling agent, heating and stirring, cooling, and drying to obtain a polypropylene compound.

Embodiment 3

[0018] A rubber material for an anti-aging traffic sign shell proposed by the present invention, its raw materials include by weight: 55 parts of polypropylene compound, 55 parts of neoprene, 35 parts of thermoplastic polyurethane elastomer, 14 parts of mica sheet, zeolite powder 13 parts, 16 parts of expanded perlite, 52 parts of precipitated barium sulfate, 3.8 parts of crosslinking agent, 2.5 parts of calcium stearate, 3.5 parts of disproportionated rosin, 1.8 parts of 4-cinnamon phenol, 2,2'-methylene bis( 4-methyl-6-tert-butylphenol) 1.8 parts, plasticizer 8 parts, lubricant 6.5 parts.

[0019] The polypropylene composite is prepared by the following process: carbon fiber is immersed in 1-hexyl-3-methylimidazolium tetrafluoroborate ethanol dilution solution with a concentration of 12wt%, filtered, dried at 70°C, and heated to 105°C. Keep warm for 3 hours, add polypropylene, calcined medical stone, and silane coupling agent, heat up to 380°C and stir for 15 minutes at a st...

Abstract

The invention discloses an antiageing rubber material for a housing of a traffic direction board. The antiageing rubber material contains the following raw materials in parts by weight: 50-70 parts of a polypropylene compound, 40-60 parts of chloroprene rubber, 30-50 parts of a thermoplastic polyurethane elastomer, 10-16 parts of a mica plate, 12-15 parts of zeolite powder, 10-18 parts of expanded perlite, 50-60 parts of precipitated barium sulphate, 3-4 parts of a crosslinking agent, 2-4 parts of calcium stearate, 2-4 parts of disproportionated rosin, 1.5-2.5 parts of 4-cinnamon phenol, 1-2 parts of 2,2'-methylene bis(4-methyl-6-tert butyl phenol), 7-10 parts of a plasticizer and 5-7 parts of a lubricant. The antiageing rubber material for the housing of the traffic direction board, disclosed by the invention, is extremely high in crosslinking density, extremely high in waterproof performance and good in antiageing property, and not only is high in tensile strength, but also has relatively great flexural modulus and relatively high notch impact strength.

Description

technical field [0001] The invention relates to the technical field of traffic signs, in particular to a rubber material for an aging-resistant traffic sign shell. Background technique [0002] Traffic signs are a collection of graphic symbols that display traffic regulations and road information. It can express traffic regulations in a vivid, specific and concise manner, and at the same time express content that is difficult to describe in words. It is used to manage traffic, indicate driving directions, and Facilities to ensure smooth roads and safe driving. Applicable to highways, urban roads and all special highways, it has the nature of laws and regulations, and vehicles and pedestrians must abide by it. Traffic signs are used to manage traffic facilities, so that road users can reach their destinations smoothly and safely, and promote smooth traffic and driving safety. However, at present, the casings for traffic signs are generally made of rubber materials, which ha...
