Abstract

The invention provides a preparation method of wear-resistant rubber, which comprises the following steps of: adding wear-resistant composite particles into an assistant, uniformly mixing the wear-resistant composite particles and the assistant, adding the mixture into natural latex, dehydrating to obtain dry glue, and vulcanizing to obtain the wear-resistant rubber. The tensile strength of the wear-resistant rubber prepared by the invention is 37-40MPa, the impact strength is 677-702kg. Cm / cm<2>, the elongation at break is 975-1255%, after an Akron abrasion test is carried out according to GB / T1689-1998, the total stroke is 1.61km, the abrasion mass is 0.012-0.015g, and good mechanical properties and abrasion resistance are achieved.

Description

technical field [0001] The invention relates to the technical field of rubber processing, in particular to a preparation method of wear-resistant rubber. Background technique [0002] As an important part of polymer materials, rubber plays an irreplaceable role in tire manufacturing and some special fields, and has become an indispensable important substance in the national economy and daily life. Statistics show that the output of the world's rubber industry has reached a considerable scale, and the annual rubber consumption is close to 17 million tons. With the globalization of the world economy, the competition in the rubber market has become increasingly fierce, the requirements for environmental protection have become increasingly stringent, and the technical requirements for high performance, low energy consumption, low material consumption, and low cost have become more urgent. Nitrile rubber has the characteristics of excellent oil resistance, heat resistance, chemi...
