Technical Field

[0001] The invention relates to the technical field of rubber, and in particular to a highly wear-resistant and weather-resistant anti-frost rubber and a manufacturing method thereof. Background Art

[0002] Shoes have a long history of development. Their main purpose is to protect people's feet from injuries and facilitate walking. The sole is the part of the shoe that is in direct contact with the ground. The wear resistance of the sole material is a key indicator to measure the quality and technical level of footwear products. At present, the soles of most shoes, such as rubber soles, are prone to rapid aging in harsh environments due to drastic changes in temperature and humidity, which affects the wear resistance of the shoes and greatly reduces the service life of the soles. Summary of the invention

[0003] Therefore, in view of the above problems, the present invention provides a highly wear-resistant and weather-resistant anti-frost rubber and a manufacturing method thereof.

[0009] A further improvement is that the bridging agent comprises 1-2 parts of S80 bridging auxiliary agent.

[0010] A method for manufacturing highly wear-resistant and highly weather-resistant anti-frost rubber comprises the following steps: S1. Weigh materials, including butadiene rubber, natural rubber and EPDM rubber, and put them into an internal mixer for kneading; S2, weighing white carbon black, polyisobutylene, SP antioxidant, Si-69 silane coupling agent and white mineral oil, and mixing them with butadiene rubber, natural rubber and EPDM rubber in an internal mixer to obtain a mixed product; S3, vulcanizing the mixed material to obtain a rubber base material, and leaving it for 24 hours for use.

[0011] A further improvement is that zinc oxide, PEG4000 active agent, paraffin wax and MB antioxidant need to be added in step S1.

[0012] A further improvement is that the mastication time in step S1 is 1-2 minutes.

[0013] A further improvement is that in step S2, white carbon black is used in advance to adsorb polyisobutylene, SP antioxidant, Si-69 silane coupling agent and white mineral oil.

[0014] Further improvement is: in step S2, the mixing temperature is 115-125°C, and the mixing time is 5-8 minutes.

[0015] A further improvement is that: before the mixed material is vulcanized in step S3, the bridging agent and the bridging auxiliary agent are weighed, and the mixed material, the bridging agent and the bridging auxiliary agent are kneaded on a wheel platform for 5-10 minutes to make them uniformly kneaded.

[0016] A further improvement is that in step S3, the mold temperature is 150-160° C. and the vulcanization time is 150-200 seconds.

[0017] The advantages and beneficial effects of the present invention are: 1. Choose butadiene rubber with good wear resistance as the base material, and easy-to-process natural rubber and EPDM rubber with strong anti-aging ability as auxiliary materials, so that it has strong wear resistance and strong anti-aging ability, thereby ensuring its service life in harsh environments and improving its functionality.

[0018] 2. The addition of polyisobutylene with excellent atmospheric resistance, aging resistance and weather resistance can improve the aging resistance, weather resistance, bending fracture resistance, ozone resistance and dielectric properties of rubber in harsh environments, reduce its absorption of water and permeability to gas, thereby greatly improving the performance of rubber, preventing the rubber from rapid aging, cracking and frost when used in harsh environments, and greatly extending the service life and performance strength of the rubber.

[0019] 3. During processing, polyisobutylene is adsorbed by white carbon black in advance, so as to utilize the strong processing performance and adsorption performance of white carbon black to improve the bonding ability of polyisobutylene and rubber, greatly improve the production efficiency and the use effect of polyisobutylene. DETAILED DESCRIPTION

[0020] The specific implementation of the present invention is further described below in conjunction with the examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention, and cannot be used to limit the protection scope of the present invention. Example 1

[0021] A highly wear-resistant and weather-resistant anti-frost rubber comprises the following raw materials in parts by weight: 70-80 parts of butadiene rubber, 10-30 parts of natural rubber, 10-20 parts of ethylene propylene diene monomer rubber, and 39.5-57 parts of a mixture.

[0022] In order to make the rubber have stronger aging resistance and weather resistance, the mixture includes: 35-45 parts of white carbon black, 1-2 parts of polyisobutylene, 0.5-1 parts of SP antioxidant, 1-3 parts of Si-69 silane coupling agent, and 2-6 parts of white mineral oil.

[0023] In order to further enhance the adsorption performance of white carbon black so as to fully combine the mixture with the rubber, the white carbon black is gas phase white carbon black.

[0024] In order to improve the activity of the rubber and strengthen some of its properties, the following raw materials are also included in weight: 9-12 parts of PEG4000 active agent, 0.55-1.0 parts of paraffin, 3-5 parts of zinc oxide, 1-2 parts of bridging agent, 1.5-3 parts of bridging auxiliary agent, and 0.5-1 parts of MB antioxidant.

[0025] The bridging agent comprises: 0.3-0.5 parts of TS80 bridging agent, 0.2-0.5 parts of D80 bridging agent, and 1-2 parts of DM80 bridging agent.

[0026] The bridging agent comprises: 1-2 parts of S80 bridging auxiliary agent.

[0027] A method for manufacturing highly wear-resistant and highly weather-resistant anti-frost rubber comprises the following steps: S1. Weigh materials, including butadiene rubber, natural rubber and EPDM rubber, and put them into an internal mixer for kneading; S2, weighing white carbon black, polyisobutylene, SP antioxidant, Si-69 silane coupling agent and white mineral oil, and mixing them with butadiene rubber, natural rubber and EPDM rubber in an internal mixer to obtain a mixed product; S3, vulcanizing the mixed material to obtain a rubber base material, and leaving it for 24 hours for use.

[0028] In order to reinforce and improve the activity of rubber, zinc oxide, PEG4000 active agent, paraffin wax and MB antioxidant need to be added in step S1.

[0029] The mastication time in step S1 is 1-2 minutes.

[0030] In order to fully utilize the strong processing performance of white carbon black and allow various agents to fully act on rubber, white carbon black is used in advance in step S2 to adsorb polyisobutylene, SP antioxidant, Si-69 silane coupling agent and white mineral oil.

[0031] In step S2, the mixing temperature is 115-125° C., and the mixing time is 5-8 minutes.

[0032] In order to assist vulcanization and thus improve the physical properties and wear resistance of the rubber, before the vulcanization of the mixed material in step S3, the bridging agent and the bridging aid are weighed, and the mixed material, the bridging agent and the bridging aid are kneaded on a wheel platform for 5-10 minutes to make them uniformly mixed.

[0033] In step S3, the mold temperature is 150-160° C., and the vulcanization time is 150-200 seconds.

[0034] The physical properties of the rubber base material obtained in Example 1 were tested, and the results are shown in Table 1.
