Abstract

The invention relates to a colourfast rubber, which comprises the following components: 100 parts of nitrile-butadiene rubber, 18 parts of DM-300, 5 parts of carbon black N330, 60 parts of white carbon black, 6 parts of zinc oxide, 1.5 parts of SA, 3 parts of polyethylene glycol, 1.5 parts of a rubber dispersing agent L-24, 2 parts of 935P, 2 parts of acrylic resin MB-2, 1 part of RH-150, 2 parts of silicon oil, 3 parts of a rubber accelerator, 0.4 part of a rubber vulcanizing agent, and 0.2 part of N-cyclohexylthiophthalimide. The colourfast rubber provided by the invention has good stability, is colourfast during use and is unlikely to decompose, especially does not decompose to cause raw material pollution when it is used as a raw material tank or contacts with the reactants, and also has good abrasion resistance.

Description

A kind of colour-fast rubber

Technical field

The invention belongs to field of rubber materials, be specifically related to a kind of colour-fast rubber.

Background technology

Rubber is a kind of resilient polymkeric substance.Rubber can be obtained from the myron of some plants, also can be artificial, both considerable application and products, such as tire, packing ring etc., in some fields, as the mechanicals of working under vibrations and foot pad etc., generally need rubber to there is good colour-fast performance, prevent the generations such as industrial raw material to pollute, or owing to fading, cause the difference of color.

Summary of the invention

The object of this invention is to provide a kind of colour-fast rubber, prevent the pollution that rubber produces when in use causing the decline of rubber performance owing to fading and using.

The present invention is achieved through the following technical solutions:

A kind of colour-fast rubber, by weight, comprise following component: 100 parts of nitrile rubbers, 18 parts of DM-300,5 parts of carbon black N330,60 parts of white carbon blacks, 6 parts, zinc oxide, SA1.5 part, 3 parts of polyoxyethylene glycol, 1.5 parts of rubber dispersion agent L-24,2 parts of 935P, 2 parts of acrylic resin MB-2,1 part of RH-150,2 parts of silicone oil, 3 parts of rubber accelerators, 0.4 part of vulcanizer, 0.2 part of N-cyclohexylthiophthalimide.

Preferably, described rubber accelerator is one or more in 2-thiol benzothiazole, N cyclohexyl 2 benzothiazole sulfenamide and 2,2'-dithio-bis-benzothiazole.

Preferably, a kind of colour-fast rubber, by weight, comprise following component: 1 part of 100 parts of nitrile rubber, 18 parts of DM-300,5 parts of carbon black N330,60 parts of white carbon blacks, 6 parts, zinc oxide, SA1.5 part, 3 parts of polyoxyethylene glycol, 1.5 parts of rubber dispersion agent L-24,2 parts of 935P, 2 parts of acrylic resin MB-2,1 part of RH-150,2 parts of silicone oil, 0.5 part of 2-thiol benzothiazole, N cyclohexyl 2 benzothiazole sulfenamide, 2,1.5 parts of 2'-dithio-bis-benzothiazoles, 0.4 part of sulphur, 0.2 part of N-cyclohexylthiophthalimide.

Beneficial effect of the present invention: colour-fast rubber good stability provided by the invention, colour-fast in use procedure, in rubber use procedure, be difficult for decomposing, while particularly contacting as raw material tank or with reactant, can not decompose the pollution that causes raw material, and wear resistance is good.

Embodiment

A kind of colour-fast rubber, by weight, comprise following component: 1 part of 100 parts of nitrile rubber, 18 parts of DM-300,5 parts of carbon black N330,60 parts of white carbon blacks, 6 parts, zinc oxide, SA1.5 part, 3 parts of polyoxyethylene glycol, 1.5 parts of rubber dispersion agent L-24,2 parts of 935P, 2 parts of acrylic resin MB-2,1 part of RH-150,2 parts of silicone oil, 0.5 part of 2-thiol benzothiazole, N cyclohexyl 2 benzothiazole sulfenamide, 2,1.5 parts of 2'-dithio-bis-benzothiazoles, 0.4 part of sulphur, 0.2 part of N-cyclohexylthiophthalimide.

Colour-fast rubber provided by the invention is processed 3h at 80 ℃, and observing rubber surface does not have shank color phenomenon, uses silk friction, there is no the color of rubber on silk, proves that this rubber does not fade.
