All-steel tire tread synthetic adhesive with high abrasion

Abstract

The invention relates to an all-steel tire tread synthetic adhesive with high abrasion in the field of rubber for tires. The synthetic adhesive comprises the following raw materials according to parts by weight: 70 of natural gum, 25 to 35 of 3-polybutadiene rubber, 3 to 5 of zinc oxide, 1.5 to 2.5 of stearinic acid, 2 to 5 of age inhibitor, 1 to 2 of protection wax, 1.5 to 3 of homogenizing agent, 1 to 2 of silane coupling agent, 50 to 60 of high-abrasion furnace black, 4 to 6 of white carbon black, 1 to 2 of sulfur, 1 to 2 of curing catalyst, 0.5 to 1.5 of vulcanization resisting reducing agent, and 0.2 to 0.5 of antiscorching agent. The abrasion wear performance index of the synthetic adhesive is from 0.15-0.16 cm<3> / 1.61 km, the requirement of the national standard is not more than 0.40 cm<3> / 1.61 km, the abrasion wear performance index of the synthetic adhesive is far higher than that of the national standard, and meanwhile, a refined rubber piece has good uniformity in the course of processing the rubber matrix comprising the raw materials. The heat generation is low in the course of using parts of semi-finished products of a tire tread in the next working procedure.

Description

technical field [0001] The invention relates to a high wear-resistant all-steel tread synthetic rubber in the field of tire rubber. Background technique [0002] At present, the tread rubber configuration of all-steel radial tires mainly includes natural rubber, butadiene rubber, styrene-butadiene rubber, zinc oxide, stearic acid, anti-aging agent, protective wax, leveling agent, high wear-resistant furnace black, sulfur and anti-scorch agent etc. In order to improve its wear resistance, the current solutions mainly include 1. Increase the content of butadiene rubber in the tread rubber in a large proportion; 2. Use super wear-resistant furnace black; 3. Use natural rubber, butadiene rubber and styrene-butadiene rubber in combination . According to the design idea of ​​the above tread rubber formula, the disadvantages of the designed tread rubber have the following aspects: ① Increase the content of butadiene rubber in the formula by a large proportion. The purpose is to u...

Problems solved by technology

However, the ensuing problem is that due to the fine particles of super wear-resistant furnace black, it is not easy to disperse in the rubber material during the rubber mixing process, which will cause uneven rubber material and reduce the performance of the rubber material; at the same time, due to the fine particles The existence of furnace black makes the tread rubber generate high heat and difficult operation during the processing of semi-finished products, which brings troubles to the production process

The finished tire has high rolling resistance and heat generation during use, which not only affects the service life of the tire but also consumes a lot of fuel, which directly increases the transportation cost

③Using three types of rubber (NR, SBR, BR) in combination with the tread rubber also has the disadvantage of generating more heat during the use of the tire, and because more synthetic rubber is used in the tread rubber, the adhesive ability of the rubber material is reduced. It is easy to cause the problem of the tread and the carcass being separated, which will also affect the service life of the tire
