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

[0022] In this example, the vulcanization system used is a sulfur vulcanization system, and the rubber powder used is 60-mesh tread rubber powder. The specific formula is: 10 parts of NR, 10 parts of SBR, 80 parts of reclaimed tread rubber, and 60-mesh tread rubber 5 parts of powder, 1.9 parts of zinc oxide, 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, and 0.36 parts of DM.

[0023] The NR / SBR / reclaimed rubber / rubber powder described in this example is combined with a truck tire gasket, and its preparation steps:

[0024] 1. Put 10 parts of natural rubber into the double-roller mill for masticating, add 10 parts of SBR, 80 parts of tread reclaimed rubber, and 5 parts of 60-mesh tread rubber powder for mixing, then add 1.9 parts of zinc oxide, stearic acid 0.9 parts, 0.3 parts of RD, 0.3 parts of 4010NA, 6.3 parts of N330, 0.9 parts of naphthenic oil, 0.54 parts of CZ, 0.36 pa...

example 2

[0030] The difference between this example and Example 1 is that the amount of 60-mesh tread rubber powder is changed, and the specific formula is: 10 parts of NR, 10 parts of SBR, 80 parts of tread reclaimed rubber, 10 parts of 60-mesh tread rubber powder, zinc oxide 1.9 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, and 0.36 parts of DM.

[0031] The NR / SBR / tread reclaimed rubber / rubber powder described in this example is combined with a truck tire backing belt, and the test results of the vulcanized rubber are shown in Table 1 and Table 2.

example 3

[0033] The difference between this example and example 1 is that the consumption of 60 mesh tread rubber powder is changed, and the specific formula is: 10 parts of NR, 10 parts of SBR, 80 parts of tread reclaimed rubber, 15 parts of 60 mesh tread rubber powder, zinc oxide 1.9 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, and 0.36 parts of DM.

[0034] The NR / SBR / tread reclaimed rubber / rubber powder described in this example is combined with a truck tire backing belt, and the test results of the vulcanized rubber are shown in Table 1 and Table 2.

Abstract

The invention discloses a preparation method of an NR / SBR / tread reclaimed rubber / rubber powder combined truck tire flap, and relates to a preparation method of a truck tire flap, in particular to a preparation method of a truck tire flap with a high performance and low cost. According to the method, natural engineering tire tread reclaimed rubber is used as a main body; NR, 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; the used vulcanization system is a sulfur vulcanization system, the used vulcanization accelerator is sulfenamide (CZ), the used anti-aging agent is an amine (RD and 4010NA) anti-aging agent, and the used reinforcing agent is N330. All the properties of the prepared rubber material can reach the national standards, and the cost is low.

Description

technical field [0001] The invention relates to a preparation method of an automobile tire bead, in particular to a preparation method of a truck tire bead combined with NR / SBR / tread reclaimed rubber / rubber powder. Background technique [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. At the same time, from the perspective of economic interests, in addition to meeting the performance requirements, the pad belt should also reduce the manufacturing cost as much as possible. [0003] The combined system of NR / SBR / tread reclaimed rubber has excellent mechanical properties and aging resistance. The introduction of rubber powder ...
