Problems solved by technology

[0006] In view of the existing nitrile rubber materials, it is difficult to balance the hardness, Mooney viscosity and compression set of the rubber material, which leads to the high hardness rubber material being easy to scorch, difficult to form and difficult to mold during the production process. In order to meet the problems of difficulty in processing and production such as flowing into the mold cavity and low production efficiency and product qualification rate, the present invention provides a nitrile rubber material, which is prepared by rationally selecting the components of the rubber material and combining the preparation method provided by the present invention. The rubber can not only meet the requirements of high hardness and low compression set, but also have low Mooney viscosity characteristics

Abstract

The invention discloses a color nitrile rubber material and a preparation method thereof and belongs to the field of rubber materials and preparation methods thereof. The color nitrile rubber material is prepared from the following main components of low-mooney nitrile rubber 1052M30, high styrene rubber S6H and oligomer ester 12-I. The method comprises the preparation steps of masterbatch mixing and two-stage vulcanization of masterbatch. The color nitrile rubber material has the characteristics of high hardness, low mooney viscosity and low compression deformation, so that the problems of processing and producing difficulties that a sizing material is easy to scorch, difficult to mold and difficult to flow into a mold cavity in the production process, and a low qualified rate of a product in an existing high-hardness sizing material are solved, the production efficiency and the qualified rate of the product are greatly improved and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of rubber materials and preparation methods thereof, and more specifically relates to a nitrile rubber material and a preparation method thereof. Background technique [0002] With the rapid development of the global home appliance industry, more and more internationally renowned home appliance manufacturers have set their sights on China, which provides a good opportunity for rubber companies to enter the global supplier of rubber home appliance parts. It is against this background that the patent applicant company produces supporting rubber parts for home appliance shock-absorbing supports for internationally renowned home appliance manufacturers. , it is not only required to ensure that the shock-absorbing support rubber parts remain stable, low-vibration, and low-noise during the working process, but also require extremely high resistance to fading and pollution. The hardness of the shock-absorbing supp...
