Low-temperature-resistant rubber for mower

Abstract

Low-temperature-resistant rubber for a mower is prepared from the following raw materials in parts by weight: 80-120 parts of nitrile rubber, 18-30 parts of cis-polybutadiene rubber, 20-30 parts of chloroprene rubber, 6-12 parts of composite compatilizer, 20-30 parts of flame retardant, 0.4-0.8 part of anti-aging agent RD, 0.4-0.6 part of anti-aging agent MB, 10-20 parts of carbon black, 8-12 parts of zinc oxide, 2-4 parts of plasticizer DOS, and 1-2 parts of vulcanizing agent DCP. Chloroprene rubber, cis-polybutadiene rubber and nitrile rubber are matched according to a proper proportion, therefore, the rubber has good oil resistance, wear resistance and aging resistance, and also has good cold resistance, mechanical property and crack resistance. A proper vulcanizing agent is selected for crosslinking and vulcanization of the rubber for forming a cross-linked network, the mechanical property and the elasticity of the rubber are improved. The anti-aging property of the low-temperature-resistant rubber can be further improved due to the cooperation of the anti-aging agent RD and the anti-aging agent MB and rubber. The low-temperature-resistant rubber can be endowed with relativelygood extension property, tear resistance, wear resistance and elasticity through the added carbon black.

Description

technical field [0001] The invention relates to the technical field of garden tools, in particular to low-temperature-resistant rubber for lawnmowers. Background technique [0002] The environment in which lawn mowers are stored in general households is basically the same as the external environment. However, in winter, the frequency of use of lawn mowers is greatly reduced, and they can only be left idle. The rubber parts on lawn mowers are easy to age in the air. , reduce the service life. Contents of the invention [0003] The object of the present invention is to provide a low-temperature-resistant rubber for lawn mowers to solve the defects that the rubber parts on the existing lawn mowers are prone to aging and shorten the service life. [0004] In order to solve the above problems, the technical scheme adopted in the present invention is as follows: [0005] A kind of low-temperature-resistant rubber for lawn mowers, which is made of the following raw materials in...
