Abstract

The invention discloses a novel compounded rubber sealing gasket material. The novel compounded rubber sealing gasket material is characterized by being prepared from the following raw materials in parts by weight: 85-90 parts of chloroprene rubber (CR121), 25-30 parts of nitrile rubber, 10-15 parts of zinc oxide, 3-5 parts of stearic acid, 10-12 parts of polytetrafluoroethylene, 9-10 parts of parachlormetaxylenol, 10-12 parts of n-propyl methacrylate, 20-24 parts of precipitated white carbon black, 5-10 parts of poly-4-mehtyl-1-amylene, 1-2 parts of N,N'-1,3-Phenylene bismaleimide, 30-35 parts of alumina powder, 1-2 parts of sulfur, 28-32 parts of N330 carbon black, 2-3 parts of accelerator M, and 10-12 parts of modified attapulgite. According to the novel compounded sealing gasket material, the technological property of rubber can be improved due to the addition of the modified attapulgite, and the toxic and side effects and environmental pollution can be reduced due to the use of an environment-friendly compounding ingredient; the material is anti-aging and corrosion-resistant, the wear and the phenomena of oil leakage and the like can be reduced, and the novel compounded rubber sealing gasket material is stable in quality, good in sealing property, and longer in service life.

Description

A kind of NEW TYPE OF COMPOSITE rubber seal cushion material and preparation method thereof

Technical field

The present invention relates to rubber composite manufacture field, particularly a kind of NEW TYPE OF COMPOSITE rubber seal cushion material and preparation method thereof.

Background technology

Gasket is a kind of for the inside such as machinery, equipment, pipeline, the material sealing.The gasket using mostly at present is rubber gasket, be characterized in: high temperature resistant, resistance to ozone, resistance to natural weathering, vacuum-resistant, fuel oil resistance, resistance to lubricating oil, powerful oxidation corrosion resistance agent, resistance to chemical reagents and electrical insulation capability are good, are widely used in national defense industry and civilian industry.The defects such as but existing rubber gasket sealing effectiveness is undesirable, wear resistance is poor, intensity is low, far can not meet actual requirement.Therefore researching and developing a kind of high-performance rubber gasket has become the task of top priority.

Summary of the invention

The object of this invention is to provide a kind of NEW TYPE OF COMPOSITE rubber seal cushion material and preparation method thereof.

In order to realize object of the present invention, the present invention passes through following scheme implementation:

A kind of NEW TYPE OF COMPOSITE rubber seal cushion material, raw material by following weight part is made: chloroprene rubber (CR121) 85-90, paracril 25-30, zinc oxide 10-15, stearic acid 3-5, ptfe micropowder 10-12, parachlormetaxylenol 9-10, propyl methacrylate 10-12, precipitated silica 20-24, poly--4-methyl-1-pentene 5-10, N, N '-penylene bismaleimides 1-2, aluminum oxide powder 30-35, sulphur 1-2, N330 carbon black 28-32, captax 2-3, attapulgite modified 10-12;

The described attapulgite modified raw material by following weight part is made: attapulgite 20-24, clay 12-15, hexamethylene diisocyanate 3-4, tri (propylene glycol) diacrylate 2-3, nano titanium oxide 3-4, nano silicon 1-2, zinc oxide 1-2, Vulcanization accelerator TMTD 1-2, Tremoliteor Tremoliteasbestos powder 8-10, Fructus Zanthoxyli oil 1-2; Preparation method puts into attapulgite, clay mixing calcining furnace and calcine 3-4 hour at 700-720 ℃, cooling, put into 10-12% hydrochloric acid soln and soak 1-2 hour, filter and take out, with clear water, clean and dry, be ground into 200-300 order powder, mix with other remaining component, grinding distribution 1-2 hour, obtains.

NEW TYPE OF COMPOSITE rubber seal cushion material of the present invention, is made by following concrete steps: paracril, zinc oxide, stearic acid, ptfe micropowder, parachlormetaxylenol are added in Banbury mixer, be heated to 80-90 ℃, mixing 3-5min; Then be warming up to 120-130 ℃, add again propyl methacrylate, precipitated silica, poly--4-methyl-1-pentene, N, a N '-penylene bismaleimides, mixing 6-8min, then add aluminum oxide powder, sulphur, N330 carbon black, promotor to continue mixing 4-6min; Then be cooled to 90-100 ℃, add the mixing 6-8min of all the other remaining components, obtain.

Excellent effect of the present invention is: the present invention adds attapulgite modified, has improved the processing performance of sizing material, uses environment-friendly type Synergist S-421 95, reduces its toxic side effect and the pollution to environment; Tool of the present invention will have ageing-resistant, corrosion-resistant, has reduced wearing and tearing, the phenomenons such as leakage of oil, constant product quality, good seal performance, longer service life.
