Abstract

The invention provides a rubber powder based material used for a dynamically vulcanized thermoplastic elastomer (TPE) waterproof roll and a preparation method thereof. The material comprises a rubber part and a plastic part. The preparation method comprises the following steps: adding modified rubber powder to the rubber part to prepare a rubber compound, fully mixing the rubber compound with the plastic part with a mixer and utilizing a twin-screw extruder to prepare a TPE, wherein under the shear action of screws, rubber is sheared into small size to become a disperse phase while being vulcanized and the plastic becomes a continuous phase, thus completing the dynamic vulcanization process. The prepared material used for the waterproof roll has excellent properties, is low in production cost and has an extensive application prospect.

Description

technical field [0001] The invention relates to a rubber powder-based dynamically vulcanized thermoplastic elastomer waterproof roll material and a preparation method thereof, belonging to the technical field of polymer waterproof roll materials. Background technique [0002] Thermoplastic elastomers have become a fast-growing variety in the field of waterproof membranes in recent years due to their good mechanical properties, weather resistance, dimensional stability, and easy weldability. As a large category of industrial solid waste, waste rubber mainly comes from rubber products such as discarded tires, rubber hoses, tapes, rubber shoes and seals, backing plate industrial miscellaneous goods, scraps and scraps generated in the production process of rubber factories Waste is also a source. The recycling of waste rubber can reduce environmental pollution and realize the recycling of resources. Due to the secondary pollution in the production process of reclaimed rubber, ...
