Embodiment 1

[0049] Tread compounds with the composition specified in Table 1 were prepared in a GK400 internal mixer in four separate addition mixing stages, namely, three non-productive mixing stages and one productive mixing stage. The three non-productive stages were mixed for about 1-3 minutes until the rubber temperature reached 160°C; the mixing time for the productive stage was to make the rubber temperature reach 115°C, about 1-2 minutes.

[0050] The specific process is as follows:

[0051] The rubber main material (cis 1,4-polyisoprene rubber, cis-butadiene-trans-butadiene copolymer synthetic rubber, styrene-butadiene copolymer synthetic rubber) and aromatic oil are subjected to 1.5~ 4 minutes of non-productive mixing until the temperature of the rubber material reaches 160 ° C, that is to say, it is completed;

[0052] After one-stage degumming and cooling, add carbon black, anti-aging agent (anti-aging agent 6PPD, anti-aging agent TMQ, protective wax) and stearic acid to the mi...

Abstract

The invention relates to the technical field of tires, in particular to a tread compound with low VOC content. Contains the following components: 100 parts by weight of rubber main material: including 1-60 parts by weight of cis-1,4-polyisoprene rubber, 1-80 parts by weight of cis-butadiene-trans-butadiene copolymer Rubber, 1-50 parts by weight of styrene-butadiene copolymer synthetic rubber; compounding agent: based on 100 parts by weight of rubber main material, the compounding agent includes 1-10 parts of cyclic oligosaccharide. Beneficial effect: the use of the cyclic oligosaccharide of the present invention significantly reduces the VOC value and atomization value of the rubber material.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a low-VOC content tread compound and its preparation method and application. Background technique [0002] During the processing of rubber products, various fillers, compounding agents and vulcanizing agents are often added to enhance the performance of rubber products. The rubber materials, fillers, compounding agents and vulcanizing agents used all contain small molecular organic compounds. Volatile organic compounds are also produced. During the use of rubber products, small molecular organic compounds in vulcanized rubber will be slowly released from the rubber, causing serious harm to the environment and human body. [0003] At present, in the prior art, the amount of volatile organic compounds is controlled from the aspect of raw materials, but it is difficult to control the amount of volatile organic compounds only from the aspect of raw materials. [0004] With the improv...
