Preparation method of rubber material for preparing high-/low-temperature resistant automobile pipeline 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 preparation method of a rubber material, in particular to a preparation method of a rubber material used in automobile engine and transmission oil cooling pipelines for preparing high and low temperature resistant automobile pipeline rubber products. Background technique

[0002] The high temperature resistance (150°C) and low temperature resistance (-40°C) performance of rubber products such as automobile engine and transmission oil cooling pipelines manufactured by the existing preparation methods are relatively low, and cannot meet the general GM6260M standard requirements.

[0003] In the prior art, the test data of rubber products made of rubber materials (chlorinated polyethylene rubber) for the oil cooling pipelines of automobile engines and transmissions are as follows:

[0004]

[0005]

[0006] It can be seen from the above experimental results that the changes in tensile strength, elongation at break, and cold flexural resi...
