Abstract
The invention provides a production formula and a production process of heat-welded pre-wetting-pavement self adhesion type POE (Polyolefin Elastomer) waterproof roll subjected to graft modification by maleic anhydride. The production process comprises the steps of adding all raw materials into an internal mixer according to the formula proportion and uniformly mixing for15min at the mixing temperature being 110 DEG C-130 DEG C, and then discharging; pouring glue on an open mill 560, reducing the temperature to be smaller than or equal to 90 DEG C, filtering impurities by a glue filter, thinning and mixing on an open mill 450, uniformly mixing and then discharging strips; conducting extrusion molding by an extruder, vulcanizing the molded roll in a continuous uniformly which is 20m long under the condition that the temperature is 170 DEG C and the pressure is 0.3MPa; and coating polypropylene fiber, dacron or acrylic on a POE layer subjected to graft modification by maleic anhydride to form a surface layer. The heat-welded pre-wetting-pavement self adhesion type POE (Polyolefin Elastomer) waterproof roll subjected to graft modification by maleic anhydride prepared by the production formula and the production process has the advantages of high strength and thermoplastic fusion property of plastics, the properties of POE, and improved adhesion strength.
