Problems solved by technology

[0006] From the above experimental results, it can be seen that the tensile strength change, elongation at break change and cold flex resistance of the existing automobile engine and transmission oil cooling pipeline rubber products made of chlorinated polyethylene rubber do not meet the general GM6260M requirements. Standard requirements; the rubber products of automotive engine and transmission oil cooling pipelines prepared by the prior art have low temperature resistance and low temperature resistance, and it is difficult to meet the increasing requirements of the automotive industry for rubber products.

Abstract

The invention discloses a preparation method of rubber material for preparing high- / low-temperature resistant automobile pipeline rubber products. The method includes (1) introducing water to cool a Banbury mixer; blending rubber material, reinforcing filler, plasticizer, activator, anti-aging agent and lubricant in the Banbury mixer; discharging under rubber temperature of below 130 DEG C; forming sheets on an open mill; and cooling to obtain master batch; and (2) inputting the master batch into the Banbury mixer; blending under uniform addition of vulcanizing agent; discharging under rubber temperature of below 90 DEG C; forming strips on the open mill; cooling and standing for aging. The produced automobile engine / transmission oil cooling pipeline rubber products have improved high- / low-temperature resistance, satisfy increasingly high requirements of automobile industry on rubber products, and accord with GM6260 M standard.

Description

technical field [0001] The invention relates to a method for preparing a rubber material, in particular to a method for preparing a rubber material used in automobile engine and transmission oil cooling pipes for preparing high and low temperature resistant automobile pipeline rubber products. Background technique [0002] The high temperature (150°C) and low temperature (-40°C) resistance of rubber products such as automotive engines and transmission oil cooling pipes produced by the existing preparation method is relatively low, and cannot meet the requirements of the general GM6260M standard. [0003] In the prior art, adopt rubber material (chlorinated polyethylene rubber) to make the test data of automobile engine and transmission oil cooling pipeline rubber products as follows: [0004] [0005] [0006] From the above experimental results, it can be seen that the tensile strength change, elongation at break change and cold flex resistance of the existing automob...
