The main purpose of latex reclaimed rubber is to replace natural rubber and reduce the production cost of various natural rubber products. In actual production, latex reclaimed rubber can be used alone or in combination with natural rubber, styrene-butadiene rubber, cis-butadiene rubber, neoprene rubber, ethylene-propylene rubber, and even polyethylene and other plastics, with low preparation cost and good performance. Rubber sealing products, especially rubber sealing strips, brake cups, etc.
(2) Latex reclaimed rubber to produce rubber seals
Rubber sealing strips are mainly used for sealing on doors and windows of vehicles, airplanes and buildings. The rubber material is required to have good weather resistance, aging resistance, ozone resistance, cold resistance, as well as certain tensile properties and small compression. deformed. When using latex reclaimed rubber to produce rubber seals, it is usually used in combination with neoprene/natural rubber/styrene-butadiene rubber, or with natural rubber/polyethylene. Some products can also use latex reclaimed rubber with natural rubber and ethylene-propylene rubber. Further improve the aging resistance of rubber sealing strips.
When using latex reclaimed rubber as the main raw material to produce rubber seals, it is recommended to use antioxidants and antioxidants together to further improve the aging resistance of the seals. In addition, when using latex reclaimed rubber to produce sponge seals, it is necessary to focus on the combination of 2ELYY317 foaming agent and vulcanizing agent, and the foaming speed of the product should match the vulcanization speed to ensure stable density and uniform pore size of the extruded seal; necessary It is also necessary to add supporting ingredients in the formula, such as ointment, polymer wax modified plastics, etc., to ensure the appearance quality of the rubber sealing strip and the stability of the structure and dimensions.
(3) Production of alcohol-type brake fluid brake cups from latex reclaimed rubber
The brake cup plays the role of pressure transmission and sealing in the automobile braking system, and requires the rubber compound to have good tensile properties, brake fluid resistance, compression set resistance, good elasticity and low temperature resistance. In actual production, the brake cups used for alcohol-based brake fluids generally use natural rubber or natural rubber combined with styrene-butadiene rubber and butadiene rubber; appropriate use of latex reclaimed rubber instead of natural rubber can ensure the quality of the product. Effectively reduce the cost of raw materials under the premise.
In actual production, the amount of zinc oxide can be appropriately increased in the brake cup compound containing latex reclaimed rubber to improve the thermal conductivity of the compound and reduce heat generation. Use an appropriate amount of anti-aging agent to further improve the anti-aging performance of the latex reclaimed rubber brake cup.
In actual production, natural latex reclaimed rubber can also be used in the production of various rubber sealing gaskets, special-shaped parts and other sealing products. When using latex reclaimed rubber to prepare rubber sealing products, manufacturers must select appropriate reclaimed rubber products according to actual needs, reasonably control the application ratio of reclaimed rubber, and appropriately adjust the production formula and process conditions. question.
