Abstract

The invention discloses a motorcycle inner tube. The motorcycle inner tube is characterized by comprising the following components: in parts by weight, 10 parts of ethylene propylene rubber, 90 partsof compounded latex, 10-50 parts of carbon black, 10-40 parts of white carbon black, 11-32 parts of a plasticizer, 3-10 parts of an active agent, 2-3 parts of an anti-aging agent, 4-23 parts of an accelerator, 1-2 parts of a vulcanizing agent and 3-20 parts of a chemical foaming agent. The invention also discloses a preparation method of the motorcycle inner tube. Compared with the prior art, themotorcycle inner tube can maintain the original appearance, support force and elastic force even if the surface layer is punctured, and normal use of the inner tube is not affected; the inner tube issoft, has strong energy absorption and impact resistance, a smooth surface, a density of 0.1-0.3 g / cm<3>, and is light, and a traditional inflatable inner tube can be replaced completely for use; andthrough plasticating, mixing, remilling, preforming, one-section vulcanization, trimming and two-section vulcanization, sufficient dispersion of the components, even and sufficient foaming and a smooth surface of the product can be achieved.

Description

technical field [0001] The invention belongs to the technical field of tire manufacturing, and in particular relates to a motorcycle inner tube and a preparation method thereof. Background technique [0002] Tires are ground-rolling circular elastic rubber products assembled on various vehicles or machinery. They are usually installed on metal rims to support the body, buffer external impact, realize contact with the road surface and ensure the driving performance of the vehicle. From a structural point of view, tires mostly include an outer tire and an inner tube. The inner tube is commonly known as the inner tire, which refers to a circular elastic tube that maintains the internal pressure of the tire and has a tire valve. The quality of the inner tube often determines the quality of the whole tire. [0003] At present, taking motorcycles as an example, most of the inner tubes are inflatable inner tubes. The manufacturing process of inflatable inner tubes is batching, pla...
