Abstract

The invention discloses a method for preparing ternary ethylene propylene vulcanized rubber powder master batches, products and application. The preparation method comprises the following steps of: mixing 40 to 100-mesh rubber powder of waste ternary ethylene propylene rubber and a large amount of softening agent or a softening agent and a vulcanization system material at normal temperature, and standing the mixture for one day and one night under common room temperature condition to obtain the ternary ethylene propylene vulcanized rubber powder master batch 1; or adding the ternary ethylene propylene vulcanized rubber powder master batch 1 into common ternary ethylene propylene mixing glue to obtain the ternary ethylene propylene vulcanized rubber powder master batch 2; or adding the ternary ethylene propylene vulcanized rubber powder master batch 1 into common conductive or antistatic ternary ethylene propylene mixing glue to obtain the conductive or antistatic ternary ethylene propylene vulcanized rubber powder master batch 3. The ternary ethylene propylene vulcanized rubber powder master batches 1, 2 and 3 can be used as independent products. The products are applied to any rubber product of a rubber plate, a coiled material, a sealing element, a shock absorption piece and a rubber roller of any one or a combined system rubber material of ternary ethylene propylene rubber and butyl rubber, wherein the tensile strength of the rubber product is 1.8 to 18MPa.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to EPDM vulcanized rubber powder, which relates to the utilization of waste rubber powder and the technology of formulating rubber products. technical background [0002] my country is a country with poor rubber resources. Today, when we pay attention to sustainable and harmonious development, people pay more and more attention to environmental protection and the regeneration of waste rubber. As a high-performance special rubber widely used in my country, EPDM rubber is currently It mainly relies on imports, and its recycling is more valuable in the field of special rubber products. However, there are currently two main methods of recycling waste EPDM rubber products. One is the high-temperature dynamic desulfurization method. Although this method has the advantage of greater elongation, it has the disadvantages of emitting waste gas and requiring a lot of power for mechanical refining...
