preparation example Construction

[0012] The preparation method of oil-resistant sealant of the present invention is:

[0013] The hydrogenated nitrile butadiene rubber and fluororubber in the formulation amount are thinly passed separately, mixed and added to the open mill, and then the remaining components are added to the open mill for mixing until uniform, and then the sheet is produced to obtain the mixed rubber. Carry out one-stage vulcanization, control the vulcanization temperature to 165°C, the vulcanization time to 35 minutes, and the vulcanization pressure to 11MPa; after taking out the rubber, perform two-stage vulcanization in an oven at 165°C for 1 hour to obtain an oil-resistant sealant.

[0014] Example 2

[0015] The formula of oil-resistant sealant of the present invention is as follows:

[0016] Hydrogenated nitrile rubber 50kg, fluorine rubber 22kg, allyl alcohol 3kg, calcium carbonate 2kg, methyl hydrogen silicone oil 1kg, stearic acid 1.8kg, magnesium dimethacrylate 2kg, light calcium ...

Embodiment

[0020] The formula of oil-resistant sealant of the present invention is as follows:

[0021] Hydrogenated nitrile rubber 60kg, fluorine rubber 18kg, allyl alcohol 5kg, calcium carbonate 4kg, methyl hydrogen silicone oil 2kg, stearic acid 1.5kg, magnesium dimethacrylate 3kg, light calcium carbonate 0.5kg, allyl alcohol 0.2 kg, oleic acid diethanolamine borate 3kg, paraffin 1.8kg, diacetyl peroxide 0.8kg, zinc oxide 0.4kg, aluminum oxide 5kg, high wear-resistant carbon black 6kg, antioxidant 0.8kg, sulfur 3kg.

[0022] The preparation method of oil-resistant sealant of the present invention is:

[0023] The hydrogenated nitrile butadiene rubber and fluorine rubber in the formula are thinly passed and mixed into the open mill, and then the remaining components are added into the open mill for mixing until uniform, and then the sheet is obtained to obtain the mixed rubber. Carry out one-stage vulcanization, control the vulcanization temperature to 170°C, the vulcanization time to...

Abstract

The invention provides an oil-resistant sealing glue. The oil-resistant sealing glue consists of the following components in parts by mass: 50-60 parts of hydrogenated butadiene-acrylonitrile rubber, 18-22 parts of fluororubber, 3-5 parts of allylalcohol, 2-4 parts of calcium carbonate, 1-2 parts of methyl hydrogen silicone oil, 1.5-1.8 parts of stearic acid, 2-3 parts of magnesium methacrylate, 0.2-0.5 part of light calcium carbonate, 0.2-0.5 part of allyl alcohol, 2-3 parts of oleic acid diethanolamine borate ester, 1.5-1.8 parts of paraffin, 0.8-1.2 parts of diacetyl peroxide, 0.2-0.4 part of zinc oxide, 9-12 parts of aluminum oxide, 6-8 parts of high-abrasion-resistance carbon block, 0.8-1.5 parts of an anti-aging agent and 1-3 parts of sulfur. The invention further provides a preparation method of the oil-resistant sealing glue. The oil-resistant sealing glue is high in sealing property, high-temperature resistance, abrasion resistance and oil resistance.

Description

technical field [0001] The invention relates to an oil-resistant sealant. Background technique [0002] Sealing products are important basic components of all kinds of machinery, and almost all industrial sectors cannot do without it. The quality of the sealing element is directly related to the service life and operational reliability of the machine. If the quality of the seals is poor, it will cause loss and trouble if it is light, and it will cause serious accidents if it is serious. Contents of the invention [0003] The invention provides an oil-resistant sealant with good oil resistance; the invention also provides a preparation method thereof. [0004] The invention provides an oil-resistant sealant. The oil-resistant sealant is composed of the following components in parts by mass: 50-60 parts of hydrogenated nitrile rubber, 18-22 parts of fluororubber, 3-5 parts of allyl alcohol, carbonic acid 2-4 parts of calcium, 1-2 parts of methyl hydrogen silicone oil, 1.5...
