Problems solved by technology

In the early stage of pre-vulcanization, we used the adhesive glue used in the traditional hot-turning process, which failed due to insufficient bonding strength. We also purchased pre-vulcanized middle cushion rubber from other manufacturers, but due to insufficient adhesive strength, the tires failed in normal use. Appearance of tread phenomenon

Embodiment 1

[0028] The pre-vulcanized middle cushion rubber of large-scale engineering tires is composed of raw materials according to parts by mass, natural rubber (GB 1#): 100 parts, zinc oxide: 3 parts, stearic acid: 1 part, rubber antioxidant RE: 1 part, Rubber antioxidant DFC-34: 1 part, rubber accelerator CZ: 0.4 parts, rubber accelerator M: 0.1 part, rubber accelerator TMTD: 0.1 part, carbon black N660: 10 parts, white carbon black: 10 parts, rubber oil : 2 parts, rubber adhesive A: 1 part, resorcinol: 1 part, C5 resin: 3 parts, rubber reinforcing agent QS-3: 2 parts, glue evenly dispersed or glue Yisu T78: 1 part, Sulfur: 1 part, rubber anti-scorch agent PVI: 0.1 part.

[0029] Jiaoyisu T78 is a carbon black dispersant produced by Qingdao Angji Rubber & Plastic Technology Co., Ltd. It can shorten the mixing time, improve the dispersion of carbon black and other powders in rubber, increase the extrusion speed, and stabilize the extrusion size. Lower extrusion temperature.

Embodiment 2

[0031] The pre-vulcanized middle cushion rubber of large-scale engineering tires is composed of raw materials according to parts by mass, natural rubber (GB 1#): 100 parts, zinc oxide: 4 parts, stearic acid: 2 parts, rubber antioxidant RE: 2 parts, Rubber antioxidant DFC-34: 2 parts, rubber accelerator CZ: 0.6 parts, rubber accelerator M: 0.3 parts, rubber accelerator TT: 1.5 parts, carbon black N660: 12 parts, white carbon black: 12 parts, rubber oil : 3 parts, rubber adhesive A: 2.5 parts, resorcinol: 2.5 parts, C5 resin: 5 parts, rubber reinforcing agent QS-3: 4 parts, glue evenly dispersed or Glue Yisu T78: 1.5 parts, Sulfur 2.5 parts, rubber anti-scorch agent PVI: 0.15 parts.

Embodiment 3

[0033] The pre-vulcanized middle cushion rubber of large-scale engineering tires is composed of raw materials according to parts by mass, natural rubber (GB 1#): 100 parts, zinc oxide: 5 parts, stearic acid: 3 parts, rubber antioxidant RE: 3 parts, Rubber antioxidant DFC-34: 3 parts, rubber accelerator CZ: 0.8 parts, rubber accelerator M: 0.4 parts, rubber accelerator TMTD: 0.4 parts, carbon black N660: 14 parts, white carbon black: 14 parts, rubber oil : 5 parts, rubber adhesive A: 4 parts, resorcinol: 4 parts, C5 resin: 7 parts, rubber reinforcing agent QS-3: 6 parts, glue evenly dispersed or glue Yisu T78: 3 parts, 4 parts of sulfur, rubber anti-scorch agent PVI: 0.2 parts.

[0034] The special method for the pre-vulcanized middle cushion rubber of the large-scale engineering tire of the above-mentioned embodiment comprises the following steps:

[0035] Step 1: put the natural rubber into the internal mixer, control the temperature to 70-80 degrees, the front and rear roto...

Abstract

The invention relates to tire procuring in-plastic-mat in a large project and a preparation method thereof, belonging to the technical fields of plastic mat and preparation method. The tire procuring in-plastic-mat in a large project in the invention is prepared by the following raw materials in parts by weight: 3-5 parts of zinc oxide prepared by 100 parts of natural gum, 1-3 parts of stearic acid, 1-3 parts of rubber antiager RE, 1-3 parts of rubber antiager DFC-34, 0.4-0.8 part of rubber promoter CZ, 0.1-0.4 part of rubber promoter M, 0.1-0.4 part of rubber promoter TMTD, 10-14 parts of carbon black N660, 10-14 parts of white carbon black, 2-5 parts of rubber oil, 1-4 parts of rubber binding agent A, 1-4 parts of resorcinol, 3-7 parts of C5 resin, 2-6 parts of rubber reinforcing agent QS-3, 1-3 parts of dispersant, 1-4 parts of sulphur and 0.1-0.2 part of rubber scorch retarder PVI. The product in the invention thoroughly solves the problem of adhesive strength of tread rubber and the casing in-plastic-mat in tyre prevulcanization in large-scale projects, and avoids the occurrence of bodiless surface of the tyre in normal use.

Description

technical field [0001] The invention relates to a cushion rubber in pre-vulcanization of large-scale engineering tires and a preparation method thereof, and belongs to the technical field of formula and process structure of rubber cushion in pre-vulcanization of tires. Background technique [0002] At present, tire retreading is a comprehensive utilization of resources, circular economy, waste utilization and environmental protection projects, and it is an industry vigorously advocated, supported and supported by the state. The pre-curing of large OTR tires is the development direction of the tire retreading industry, but the bonding strength between the tread rubber and the cushion rubber in the carcass is the biggest problem that plagues the pre-curing of large OTR tires. In the early stage of pre-vulcanization, we used the adhesive glue used in the traditional hot-turning process, which failed due to insufficient bonding strength. We also purchased pre-vulcanized middle c...
