Embodiment 1

[0012] Embodiment 1 of the present invention: The general-purpose wear-resistant rubber pad is made by the conventional manufacturing process with the raw materials of the following weight proportions, and is hot-pressed into a shoe sole in an abrasive tool. 9 parts of 3L natural rubber, 9 parts of styrene-butadiene rubber, 12 parts of butadiene rubber, 5 parts of ethylene-vinyl acetate copolymer EVA-180, 16.5 parts of carbon black (9 parts of N220 carbon black, 7.5 parts of N330 carbon black), clay 2 0.67 parts of stearic acid, 1.65 parts of coumarone, 1.4 parts of zinc oxide, 1 part of accelerator (DM0.4 part, M0.25 part, RD0.35 part), 46 # 1 part of engine oil, 6 parts of sulfur. The sole has good wear resistance and can satisfy long-term wear.

Embodiment 2

[0013] Embodiment 2 of the present invention: use the raw materials of the following weight proportions to make general-purpose wear-resistant rubber pads by conventional manufacturing techniques, and make pads of different shapes and specifications as required. 11 parts of 3L natural rubber, 11 parts of styrene-butadiene rubber, 13.5 parts of butadiene rubber, 7 parts of ethylene vinyl acetate copolymer EVA-180, 18 parts of carbon black (10 parts of N220 carbon black, 8 parts of N330 carbon black), 3 parts of clay , 0.55 parts of stearic acid, 1.8 parts of coumarone, 1.0 parts of zinc oxide, 1 part of accelerator (DM0.4 part, M0.25 part, RD0.35 part), 46 # 0.8 parts of engine oil, 4 parts of sulfur. This kind of mat has good wear resistance and can meet long-term wear.

Abstract

The present invention discloses a current wear resistant rubber mat, the current wear resistant rubber comprises following parts by weight of materials: 8-11 parts by weight of caoutchouc, 8-11 parts by weight of styrene butadiene rubber, 11-13.5 parts by weight of butadiene rubber, 4-7 parts by weight of vinyl chloride-vinyl acetate copolymer, 15-18 parts by weight of carbon black, 1-3 parts by weight of argil, 0.55-0.75 part by weight of stearic acid, 1.5-1.8 parts by weight of coumarone, 1.0-2.0 parts by weight of zinc oxide, 1 part by weight of accelerant, 0.8-1.2 parts by weight of machine oil, 4-7 parts by weight of sulfur, produced by adopting a normal technology. The invention has perfect abrasion resistance, improving the life-span of shoes and mats greatly, protecting workpieces and equipments.

Description

technical field [0001] The invention relates to a rubber pad, in particular to a general wear-resistant rubber pad. Background technique [0002] In daily life and work places, due to the constant friction between objects and workpieces, as the friction time increases, the appearance of the object will be damaged or even lose its original performance. For example, the sole of the shoe needs to have a certain wear resistance to ensure that people will not be easily worn out after daily walking or running sports, so that the shoe can be used for a longer time; there are also rubber gaskets to prevent wear and tear, so as to maintain Good sealing effect. At present, the performance of wear-resistant rubber pads on the market is different, and the price gap is large. Therefore, it is of practical significance to increase the wear resistance of rubber pads and reduce production costs. Contents of the invention [0003] The purpose of the present invention is to provide a new ...
