A kind of terpolymer EP rubber acrylic resin Rubber gasket material and preparation method thereof
Technical field
The present invention relates to rubber composite manufacture field, particularly a kind of terpolymer EP rubber acrylic resin Rubber gasket material and preparation method thereof.
Background technology
Gasket is a kind of for inside such as machinery, equipment, pipelines, the material sealed.The gasket of current use mostly 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.But the defects such as existing rubber gasket sealing effectiveness is undesirable, wear resistance is poor, intensity is low, far can not meet actual requirement.Therefore research and develop a kind of high-performance rubber gasket and become the task of top priority.
Summary of the invention
The object of this invention is to provide a kind of terpolymer EP rubber acrylic resin Rubber gasket material and preparation method thereof.
In order to realize object of the present invention, the present invention is by following scheme implementation:
A kind of terpolymer EP rubber acrylic resin Rubber gasket material, is made up of the raw material of following weight part: terpolymer EP rubber (bright Sheng 2470) 60-65, acrylic elastomer 10-12, phthalic ester 12-15, zinc oxide 3-4, stearic acid 2-3, carbon black 30-34, N-phenyl-a-naphthylamine 1-2, tributyltin chloride 1-2, distearyl dimethyl ammonium chloride 1-2, anti-aging agent ODA1-2, altax 3-4, sulphur 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; Attapulgite, clay mixing are put into calcining furnace and calcine 3-4 hour at 700-720 DEG C by preparation method, cooling, put into 10-12% hydrochloric acid soln and soak 1-2 hour, filter and take out, clean with clear water and dry, be ground into 200-300 order powder, mix with other remaining component, grinding distribution 1-2 hour, to obtain final product.
Terpolymer EP rubber acrylic resin Rubber gasket material of the present invention, be made up of following concrete steps: terpolymer EP rubber (bright Sheng 2470), phthalic ester, zinc oxide, stearic acid are added in Banbury mixer, be heated to 80-90 DEG C, mixing 3-5min; Then be warming up to 145-160 DEG C, then add carbon black, N-phenyl-a-naphthylamine, tributyltin chloride, mixing 6-8min, then add distearyl dimethyl ammonium chloride, anti-aging agent ODA, altax, sulphur continues mixing 4-6min; Add the mixing 6-8min of all the other remaining components, to obtain final product.
Excellent effect of the present invention is: the present invention adds attapulgite modified, improves the processing performance of sizing material, uses environment-friendly type Synergist S-421 95, reduces its toxic side effect and the pollution to environment; The present invention fills a prescription rationally, has good mechanical property and higher intensity, stopping property and ageing resistance good, and technique is simple, and cost is low, safety non-toxic.
Embodiment
Below by specific examples, the present invention is described in detail.
