Abstract

The invention discloses an enhanced water-proof coiled material and a preparation method thereof used for reducing the application cost of the water-proof coiled material and improving the performance of the water-proof coiled material. The components of the enhanced water-proof coiled material include ethylene propylene diene rubber, polyethylene and polypropylene. The preparation method of the enhanced water-proof coiled material includes as follows: the ethylene propylene diene rubber, the polyethylene, the polypropylene, an active modifier, an antioxidant, an ultraviolet screening agent and zinc stearate are mixed and stirred; rolling is carried out on the materials after being uniformly mixed and stirred; after the materials are cooled, the materials are cut into coils. The invention can effectively reduce the application cost of the water-proof coiled material and improve the performance of the water-proof coiled material.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a reinforced waterproof coiled material and a preparation method thereof. Background technique [0002] With the development of the construction industry, users have put forward higher and higher requirements for the construction quality of the construction industry, especially for waterproofing. [0003] A kind of high-grade waterproof coiled material in the prior art is made of ethylene-propylene-diene rubber (EPDM). Since EPDM has no fixed melting point, the waterproof coiled material is mainly cold-bonded with an adhesive in the prior art. bonding. [0004] However, when a large number of waterproof rolls are used, the materials in the prior art need a large amount of adhesive to bond the waterproof rolls, thus increasing the application cost of the waterproof rolls. Contents of the invention [0005] The embodiments of the present invention provide an enhanced waterproof...
