Abstract
The invention relates to a rubber metal sleeve and a preparation process thereof. The rubber metal sleeve comprises a rubber pipe, a metalpipe and an adhesive layer, the rubber pipe comprises the following raw materials in parts by weight: 70-80 parts of butadiene rubber, 20-30 parts of ethylene propylene dienemonomer, 7-10 parts of coumarone, 5-7 parts of nano zinc oxide, 10-20 parts of a filler, 3-5 parts of a plasticizer, 2-3 parts of an accelerant, 2-3 parts of sulfur, 1-2 parts of an anti-aging agent and 0.5-1.5 parts of a lubricant. The adhesive layer comprises the following raw materials in parts by weight: 4-6 parts of epoxy resin, 2-3 parts of liquid polysulfide rubber, 0.5-1 parts of silanecoupling agent, 1.5-2.5 parts of polymethylene polyphenyl polyisocyanate, 1-2 parts of methyl phenyl silicone resin, 0.1-0.3 parts of polytetrafluoroethylenewaxpowder, 0.2-0.5 parts of white carbon black and 0.3-0.5 parts of titanium dioxide. The bonding strength between the rubber pipe and the metal pipe is improved through the adhesive layer, so that the bonding strength of the rubber metal sleeve is improved, and the service life of the rubber metal sleeve is prolonged.
Description
technical field [0001] The invention relates to the technical field of composite pipes, in particular to a rubber-metal sleeve and a preparation process thereof. Background technique [0002] Rubber and metal are two materials with different properties. Bonding the two can make composite parts with different configurations and characteristics. This composite system has a wide range of uses in industry, such as automobile industry, machinery manufacturing industry, solid Flexible joints of rocket engines, support cushions of bridges, etc. Because the metal pipe is durable, non-toxic, safe and environmentally friendly, and its corrosion resistance and durability are very good, it is suitable for fluid transportation, such as pipelines for tap water, gas, heating, etc. Generally, in order to reduce the impact of fluid on metal pipes, Generally, soft materials such as pearl cotton and sponge are wrapped outside the metal tube to absorb the impact force of the fluid in the tube ...
