Abstract
The invention discloses a high-temperature-resistant rubber gasket. The high-temperature-resistant rubber gasket is prepared from the following raw materials in parts by weight: 50-70 parts of chloroprene rubber, 10-13 parts of nanometer zinc oxide, 5-8 parts of a high-temperature-resistant material, 7-10 parts of stearic acid, 2-7 parts of carbon black and 1-2 parts of an accelerator. Since nanometer zinc oxide and the high-temperature-resistant material, namely, a polyacrylonitrile-based carbon fiber are added in the preparation process of the high-temperature-resistant rubber gasket, the high-temperature resistance of the rubber gasket can be significantly improved, the rubber gasket can operate at a high temperature in a long term and the service life of the rubber gasket is prolonged by 1.5 times compared with that of the conventional rubber gasket.
Description
Technical field
The present invention relates to rubber pad technical field, especially a kind of high-temperature resistant rubber pad.
Background technology
Rubber pad is that the slice-shaped rubber item sealed between metal flange or other connecting portion two static surface is referred to as rubber sheet gasket, is widely used in various mechanical means, plays the effects such as liner, sealing, buffering.According to the difference of the rubber constituent wherein contained, rubber pad is divided into paracril pad, viton pad, chloroprene rubber pad, natural rubber pad, ethylene-propylene-diene monomer rubber cushion and silicone rubber pad etc.
Rubber pad is in use inevitably aging, and the factor that rubber pad is aging is many, and comprising oxygenizement, and heat, oxygen acting in conjunction is extremely common, and in certain temperature range, heat can encourage oxygenizement.Traditional rubber pad in use, when its temperature exceedes certain limit, can cause rubber to produce thermo-cracking, cause rubber pad use properties sharply to reduce, and substantially reduce its work-ing life.Therefore, the problem of aging that the good rubber pad of a kind of resistance to elevated temperatures of research causes because of non-refractory to solve rubber pad is badly in need of.
Summary of the invention
The object of this invention is to provide a kind of high-temperature resistant rubber pad, this high-temperature resistant rubber pad can solve the problem of aging that rubber pad causes because of non-refractory.
In order to solve the problem, the technical solution used in the present invention is: this high-temperature resistant rubber pad, be prepared from by the raw material of following parts by weight: chloroprene rubber 50 parts ~ 70 parts, nano zine oxide 10 parts ~ 13 parts, high temperature material 5 parts ~ 8 parts, stearic acid 7 parts ~ 10 parts, carbon black 2 parts ~ 5 parts, promotor 1 part ~ 2 parts.
Further, the parts by weight of described raw material are: chloroprene rubber 50 parts, nano zine oxide 13 parts, high temperature material 5 parts, stearic acid 7 parts, carbon black 5 parts, promotor 1 part.
Further, the parts by weight of described raw material are: chloroprene rubber 70 parts, nano zine oxide 10 parts, high temperature material 6.5 parts, stearic acid 8.5 parts, carbon black 2 parts, promotor 1.5 parts.
Further, the parts by weight of described raw material are: chloroprene rubber 60 parts, nano zine oxide 12 parts, high temperature material 8 parts, stearic acid 10 parts, carbon black 3.5 parts, promotor 2 parts.
Further, described high temperature material is polyacrylonitrile carbon fiber.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
This high-temperature resistant rubber pad comprises the compositions such as chloroprene rubber, stearic acid, carbon black, promotor, and in preparation process, with the addition of nano zine oxide and high temperature material-polyacrylonitrile carbon fiber, its resistance to elevated temperatures is significantly improved, this high-temperature resistant rubber pad can at high temperature work for a long time, and its work-ing life, relative conventional rubber pad increased 1.5 times.
