Problems solved by technology

[0002] The cushion belt plays an auxiliary role in the tire and is placed between the inner tube and the rim to protect the inner tube from the wear of the rim during the running of the car. It only plays an auxiliary role in the tire, but if its quality is not up to standard, it will lead to the overall scrapping of the tire , so it is required to have good mechanical properties and aging resistance

example 1

[0023] In this example, the vulcanization system used is sulfur vulcanization system, the rubber powder used is 60 mesh tread rubber powder, the specific formula is: BR 10 parts, SBR 10 parts, tread reclaimed rubber 80 parts, 60 mesh tread rubber 5 parts powder, 1.9 parts zinc oxide, 0.9 parts stearic acid, 0.3 parts RD, 0.3 parts 4010NA, 6.3 parts N330, 0.9 parts naphthenic oil, 0.72 parts S, 0.54 parts CZ, 0.36 parts DM.

[0024] In this example, the BR / SBR / reclaimed rubber / rubber powder is used with truck tire cushion belt, and the preparation steps are as follows:

[0025] 1. Put 10 parts of BR, 10 parts of SBR, 80 parts of tread reclaimed rubber, 5 parts of 60 mesh tread rubber powder on the double-roll mill for mixing, then add 1.9 parts of zinc oxide, 0.9 parts of stearic acid, RD 0.3 Parts, 4010NA 0.3 parts, N330 6.3 parts, naphthenic oil 0.9 parts, CZ 0.54 parts, DM 0.36 parts, and finally 0.72 parts S is added. After that, the rubber compound is packaged 10 times, mixed e...

example 2

[0031] The difference between this example and example 1 is that the dosage of 60 mesh tread rubber powder is changed. The specific formula is: BR 10 parts, SBR 10 parts, tread reclaimed rubber 80 parts, 60 mesh tread rubber powder 10 parts, zinc oxide 1.9 Parts, 0.9 parts of stearic acid, 0.3 parts of RD, 0.3 parts of 4010NA, 6.3 parts of N330, 0.9 parts of naphthenic oil, 0.72 parts of S, 0.54 parts of CZ, 0.36 parts of DM.

[0032] In this example, the BR / SBR / tread reclaimed rubber / rubber powder is used in combination with truck tire cushion belts. The test results of the vulcanized rubber are shown in Table 1 and Table 2.

example 3

[0034] The difference between this example and example 1 is that the dosage of 60 mesh tread rubber powder is changed. The specific formula is: BR 10 parts, SBR 10 parts, tread reclaimed rubber 80 parts, 60 mesh tread rubber powder 15 parts, zinc oxide 1.9 Parts, 0.9 parts of stearic acid, 0.3 parts of RD, 0.3 parts of 4010NA, 6.3 parts of N330, 0.9 parts of naphthenic oil, 0.72 parts of S, 0.54 parts of CZ, 0.36 parts of DM.

[0035] In this example, the BR / SBR / tread reclaimed rubber / rubber powder is used in combination with truck tire cushion belts. The test results of the vulcanized rubber are shown in Table 1 and Table 2.

Abstract

The invention discloses a preparation method of a BR / SBR / tread reclaimed rubber / rubber powder combined autotruck tire flap, relates to a preparation method of an autotruck tire flap, and concretely relates to a preparation method of an autotruck tire flap with high performances and low cost. According to the method, natural engineering tire tread reclaimed rubber is used as a main body, BR, SBR and rubber powder (30-mesh tread rubber powder, 60-mesh tread rubber powder, 30-mesh common rubber powder and 60-mesh common rubber powder) are used as matrix rubber, a vulcanization system is a sulfurvulcanization system, a vulcanization accelerator is sulfenamide (CZ), an anti-aging agent is amine (RD and 4010NA) anti-aging agent, and a reinforcing agent is N330. All the properties of the prepared rubber material can reach the national standard, and the cost is low.

Description

Technical field [0001] The present invention relates to a preparation method of automobile tire cushion belt, in particular to a preparation method of BR / SBR / tread reclaimed rubber / rubber powder combined truck tire cushion belt. Background technique [0002] The cushion belt plays an auxiliary role in the tire. It is placed between the inner tube and the rim to protect the inner tube from rim wear during the driving of the car. It only plays an auxiliary role in the tire, but if its quality is unqualified, it will cause the overall tire to be scrapped. , So it is required to have good mechanical properties and aging resistance. At the same time, from the perspective of economic benefits, in addition to meeting the performance requirements of the mat, it is necessary to reduce the manufacturing cost as much as possible. [0003] The BR / SBR / tread reclaimed rubber combined system has excellent mechanical properties and aging resistance. The introduction of rubber powder plays a role ...
