Problems solved by technology

As we all know, rubber has valuable use value only after being vulcanized. Therefore, a series of physical and mechanical properties of rubber can be greatly improved by a suitable vulcanization compounding agent in the rubber formula. There are still deficiencies in the mechanical properties, high temperature resistance, aging resistance and reduction of compression set, which need to be further improved to increase the service life of high temperature resistant rubber

Embodiment 1

[0021] Use an open mill to masticate high-temperature-resistant raw rubber for 10 minutes to 15 minutes at room temperature using the thin pass method, adjust the roller distance to 0.4mm to 0.8mm, adjust the roller speed ratio to 1:1.25 to 1:1.27, and masticate After completion, adjust the roller distance to 1.5mm to 2.5mm, adjust the roller speed ratio to 1:1.10 to 1:1.20, and then carry out mixing. The mixing temperature is 55°C to 70°C, and the mixing time is 6min to 15min. During the refining process, add the high temperature resistant rubber vulcanizing agent prepared by 0.25g of anti-scorch agent component, 25g of vulcanizing agent component, 1g of accelerator component, 2g of active agent component, 0.5g of stearic acid, and other components. There are fillers. After the mixing is completed, put the high-temperature-resistant rubber into the vulcanization tank. The vulcanization temperature is set to 151°C, and the vulcanization time is set to 30 minutes. After the vulc...

[0023] Use an open mill to masticate high-temperature-resistant raw rubber for 10 minutes to 15 minutes at room temperature using the thin pass method, adjust the roller distance to 0.4mm to 0.8mm, adjust the roller speed ratio to 1:1.25 to 1:1.27, and masticate After completion, adjust the roller distance to 1.5mm to 2.5mm, adjust the roller speed ratio to 1:1.10 to 1:1.20, and then carry out mixing. The mixing temperature is 55°C to 70°C, and the mixing time is 6min to 15min. Add high-temperature-resistant rubber vulcanizing agent prepared by 1g of anti-scorch agent, 40g of vulcanizing agent, 2g of accelerator, 10g of active agent, 2g of stearic acid in the refining process, and the existing fillers of other components. Put the high-temperature rubber into the vulcanization tank, set the vulcanization temperature to 151°C, and set the vulcanization time to 30 minutes. After the vulcanization is completed, the material can be discharged.

Abstract

The invention discloses the technical field of vulcanization compounding agents, and the specific field is a high-temperature-resistant rubber vulcanizing agent, which consists of a vulcanizing agent component, an accelerator component, an active agent component, an anti-scorch agent component and stearic acid. Using bisulphide as a vulcanizing agent component can effectively improve the mechanical properties, high temperature resistance and aging resistance of high temperature resistant rubber; using zinc oxide as an active agent component can buffer the vulcanization system, so it can be used for high temperature resistant rubber Play the role of softening and plasticizing, effectively reducing the sticking phenomenon of high-temperature resistant rubber during mixing and reducing the compression permanent deformation of high-temperature-resistant rubber; using o-hydroxybenzoic acid as an anti-scorching agent component can prevent Early vulcanization phenomenon occurs during vulcanization to ensure that it is vulcanized at a suitable vulcanization temperature, prevent high temperature resistant rubber from scorching due to high temperature during processing, improve the operation safety of high temperature resistant rubber and increase its storage life .

Description

technical field [0001] The invention relates to the technical field of vulcanization compounding agents, in particular to a high-temperature-resistant rubber vulcanizing agent. Background technique [0002] Under the action of rubber for a long time under high temperature environment, the molecular chain will be destroyed or further cross-linked, resulting in embrittlement or softening. Therefore, high temperature resistant rubber has been widely used in various industries, such as EPDM rubber, because Its main chain is composed of chemically stable saturated hydrocarbons, and only contains unsaturated double bonds in the side chains, so it has excellent high temperature resistance, ozone resistance and aging resistance, and can be widely used in automotive parts, wire and cable protection Covers, high temperature resistant hoses, high temperature resistant tapes and seals and other fields. As we all know, rubber has valuable use value only after being vulcanized. Therefore...
