Embodiment 1

[0022] This embodiment discloses a colored material suitable for SBR thick products, including the following raw materials in parts by weight: 4 parts of EPDM rubber, 18 parts of styrene-butadiene rubber, 13 parts of butadiene rubber, 16 parts of white carbon black, titanium 7 parts of white powder, 9 parts of magnesium oxide, 9 parts of light calcium, 12 parts of paraffin oil, 1.2 parts of SI-69 silane coupling agent, 3.4 parts of zinc oxide, 0.7 parts of SP-P type antioxidant, 0.4 parts of stearic acid, 1.1 parts of PEG4000 type polyethylene glycol, 1.4 parts of IS-75 type vulcanizing agent, 0.1 part of accelerator TMTD, 0.25 parts of accelerator DM and 0.25 parts of accelerator CZ.

[0023] Improve the weather resistance of SBR by using EPDM rubber in combination, achieve better operability on rolls (non-stick rolls) by using butadiene rubber in combination, increase the strength of SBR by using white carbon black, and reduce the formula by using light calcium carbonate cos...

Embodiment 2

[0030] The difference between this example and Example 1 is that the raw materials are formulated according to the following proportions: 6 parts of EPDM rubber, 22 parts of styrene-butadiene rubber, 13 parts of butadiene rubber, 12 parts of white carbon black, 4 parts of titanium dioxide, oxidized 10 parts of magnesium, 11 parts of light calcium, 8 parts of paraffin oil, 1.2 parts of SI-69 type silane coupling agent, 3.6 parts of zinc oxide, 0.8 parts of SP-P type anti-aging agent, 0.3 parts of stearic acid, PEG4000 type polyethylene glycol 1.0 parts of alcohol, 1.4 parts of IS-75 vulcanizing agent, 0.06 parts of accelerator TMTD, 0.3 parts of accelerator DM and 0.4 parts of accelerator CZ.

[0031] In addition, the standing time of step S11 was changed to 12 hours.

Embodiment 3

[0033] The difference between this example and Example 1 is that the raw materials are formulated according to the following proportions: 8 parts of EPDM rubber, 20 parts of styrene-butadiene rubber, 11 parts of butadiene rubber, 14 parts of white carbon black, 5 parts of titanium dioxide, oxidized 15 parts of magnesium, 13 parts of light calcium, 10 parts of paraffin oil, 1.0 parts of SI-69 type silane coupling agent, 3.8 parts of zinc oxide, 0.8 parts of SP-P type anti-aging agent, 0.5 parts of stearic acid, PEG4000 type polyethylene glycol 1.0 parts of alcohol, 1.2 parts of IS-75 vulcanizing agent, 0.06 parts of accelerator TMTD, 0.3 parts of accelerator DM and 0.3 parts of accelerator CZ.

Abstract

The invention relates to a colored material suitable for an SBR thick product and a preparation method. The colored material is prepared from the following raw materials in parts by weight: 4-10 partsof ethylene propylene diene monomer, 18-22 parts of butadiene styrene rubber, 9-13 parts of butadiene rubber, 12-16 parts of white carbon black, 4-7 parts of titanium dioxide, 9-15 parts of magnesiumoxide or aluminum oxide, 9-13 parts of light calcium carbonate, 8-12 parts of paraffin oil, 1.0-1.2 parts of silane coupling agent, 3.4-3.8 parts of zinc oxide, 0.6-0.8 part of antioxidant, 0.3-0.5 part of stearic acid, 1-1.2 parts of polyethylene glycol, 1.2-1.4 parts of a vulcanizing agent and 0.56-0.9 part of an accelerant. The weather resistance of the SBR rubber material can be effectively improved, and the problem of difference of internal and external vulcanization degrees of a thick product caused by poor thermal conductivity of the rubber material is effectively solved.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a colored material suitable for SBR thick products and a preparation method. Background technique [0002] In the current production process of domestic rubber factories, some products with required colors are often encountered. During the production process, problems such as rubber sticking to the roller, sticking to the mold, blooming, long curing time, cracking of the alignment (burst edge), and color change are often encountered. Especially for thick products, these problems are more likely to occur. In the production of thick products, many domestic factories currently use post-effect vulcanization systems to solve such problems. This is an effective means, but at the same time there are many problems. That is uneven vulcanization, especially the central part of the product, there is often insufficient vulcanization, and there are honeycomb holes in the center of ...
