Abstract

The invention discloses a rubber powder industrial wheel which consists of the following raw materials in parts by weight: 80-120 parts of refined rubber powder, 1-4 parts of a wax, 1-4 parts of stearic acid, 1-4 parts of a coumarone resin, 5-15 parts of powdered sulfur and 1-5 parts of a rubber vulcanization accelerator. A preparation method comprises the following steps: (1) preparing the refined rubber powder, namely crushing and grinding waste tires into granules of which the diameter is 0.16-0.18mm; and (2) blending materials according to a ratio, and carrying out stirring, vulcanization,finishing and packaging, wherein the stirring temperature is 70-75 DEG C, the stirring time is 180-200S, the vulcanization temperature is 160+ / -5 DEG C, the pressure is 170kg / cm<2>, and the time is 1000-3600S. The rubber powder industrial wheel disclosed by the invention is capable of bearing a weight of 200-500kg, both the economical efficiency of wheel cost is ensured, and the high strength andwearing resistance of the wheel are ensured.

Description

technical field [0001] The invention relates to a rubber powder mining wheel. Background technique [0002] Rubber powder mining wheels are ground-rolling circular elastic rubber products assembled on various vehicles or machinery. They are usually installed on metal hubs to support the body and relieve external impact. The disadvantages of existing industrial and mining wheels are: poor wear resistance during use, high rubber cost, and poor physical properties. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rubber powder mining wheel and its preparation method, which can carry a weight of 200-500kg, which not only ensures the economical cost of the wheel, but also ensures the high strength and wear resistance of the wheel. The specific gravity is only 1.2-1.3g / cm³. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [000...
