Problems solved by technology

In the construction of the building waterproof layer, it is necessary to lay waterproof membranes on a large scale. Ordinary rubber waterproof membranes are mostly bonded with adhesives and adhesive tapes. This bonding method has the problem that the overlapping parts of the membranes are not bonded firmly. , prone to cracking and other problems, which affect the overall waterproof effect of the coil, cannot form an overall waterproof layer, and the adhesive and adhesive tape cannot have the same life as the main coil

Abstract

The invention discloses a rubber waterproof coiled material and a preparation method thereof. The preparation method comprises the following steps that a polyolefin thermoplastic elastomer, a polyolefin hot welding agent and a reinforcing agent are subjected to gelatinizing under a first environmental condition to obtain a first colloid; granulation treatment is conducted on the first colloid to obtain a first particulate material; the first particulate material, low-density polyethylene and composite antioxidant master batch are mixed and extruded to obtain the rubber waterproof coiled material. According to the preparation method of the rubber waterproof coiled material provided by the invention, the polyolefin thermoplastic elastomer, the polyolefin hot welding agent, the reinforcing agent and the like are subjected to gelatinization, granulation and extrusion treatment so that the rubber waterproof coiled material with weldability can be prepared.

Description

technical field [0001] The present application relates to the technical field of waterproof membranes, in particular to a rubber waterproof membrane and a preparation method thereof. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls, as an engineering foundation and building There is no leakage connection between objects, and it is the first barrier for the waterproofing of the whole project, which plays a vital role in the whole project. In the construction of the building waterproof layer, it is necessary to lay waterproof membranes on a large scale. Ordinary rubber waterproof membranes are mostly bonded with adhesives and adhesive tapes. This bonding method has the problem of weak bonding of the overlapping parts of the membranes. , prone to cracking and other problems, which aff...
