Embodiment Construction

[0009] The present invention will be described in detail below through specific examples.

[0010] A gasket material compounded by natural rubber butadiene rubber, made of the following raw materials in parts by weight (kg): 50 natural rubber, 30 butadiene rubber, 3 magnesium oxide, 2 stearic acid, 40201 anti-aging agent, Dimethyl 5-Nitroisophthalate 6, Sulfur 1, Calcium Stearate 1, Isooctyl Tin Dimethyldithioglycolate 1, Accelerator DTDM1, N351 Carbon Black 30, Soybean Oil 3, Nano Diatoms Soil 22, modified attapulgite 10;

[0011] The modified attapulgite is made of the following raw materials in parts by weight (kg): attapulgite 20, clay 20, 1,6-hexamethylene diisocyanate 3, tripropylene glycol diacrylate 4, alum 5, iron ore Slag 1, polytetrafluoroethylene 4, silane coupling agent KH-5502, silicon carbide 4, zinc oxide 8, 2,6-di-tert-butyl p-cresol 1, pepper seed oil 1; the preparation method is to make attapulgite , clay, and iron slag are mixed and put into a calciner, c...

Abstract

The invention discloses a sealing gasket material formed by compounding natural rubber and butadiene rubber. The sealing gasket material is characterized by being prepared form the following raw materials in parts by weight: 50-55 parts of natural rubber, 30-35 parts of butadiene rubber, 3-4 parts of magnesium oxide, 2-3 parts of stearic acid, 1-2 parts of anti-aging agent 4020, 6-9 parts of dimethyl 5-nitroisophthalate, 1-2 parts of sulphur, 1-2 parts of calcium stearate, 1-2 parts of tin dimethyl diisooctyl thioglycolate, 1-2 parts of accelerant DTDM (dithiodimorpholine), 30-35 parts of N351 carbon black, 3-4 parts of soybean oil, 22-25 parts of nanometer kieselguhr and 10-12 parts of modified attapulgite. According to the sealing gasket material, by adding the modified attapulgite, the process property of a rubber material is improved; by using an environment-friendly compounding agent, the toxic and side effects and the pollution to the environment are reduced. The sealing gasket material has better mechanical property, corrosion resistance and sealing property, and is simple in process, low in cost and suitable for industrialized production.

Description

technical field [0001] The invention relates to the field of processing rubber composite materials, in particular to a gasket material made of natural rubber butadiene rubber and a preparation method thereof. Background technique [0002] Gasket is a material used for sealing inside machinery, equipment, pipelines, etc. The gaskets currently used are mostly rubber gaskets, which are characterized by high temperature resistance, ozone resistance, natural aging resistance, vacuum resistance, fuel oil resistance, lubricating oil resistance, strong oxidant resistance, chemical resistance and good electrical insulation performance. Widely used in defense industry and civilian industry. However, the existing rubber gaskets have defects such as unsatisfactory sealing effect, poor wear resistance and low strength, which are far from meeting the actual requirements. Therefore researching and developing a kind of high-performance rubber gasket has become the task of top priority. ...
