Abstract

The invention discloses a polyvinyl chloride waterproof roll material and a preparation method thereof, and belongs to the field of high molecular materials. The polyvinyl chloride waterproof roll material is characterized in that the polyvinyl chloride waterproof roll material is formed by compositing outer polyvinyl chloride composition waterproof layers and inner polyvinyl chloride fiber textile framework enhancement layers alternately. After materials are mixed, a multiple extruding machine joint extruding and rolling process is adopted, the polyvinyl chloride composition layers are located between an upper layer, a lower layer and the polyvinyl chloride fiber textile layers of the roll material, the extrusion temperature is 160-190 DEG C, and the setting temperature is 180-210 DEG C. Polyvinyl chloride fiber textiles are used as enhancement materials, and the flame retardant performance is achieved while the strength of the PVC waterproof roll material is improved; the performance of the polyvinyl chloride fiber textiles is close to that of a PVC waterproof layer, so that surface treatment is not needed during usage; and the polyvinyl chloride waterproof roll material is good in durability and easy to recycle.

Description

technical field [0001] A polyvinyl chloride waterproof coiled material and a preparation method thereof belong to the field of polymer materials. Background technique [0002] At present, the problem of roof water leakage in my country is very serious. According to the survey and statistics of relevant departments, the leakage rate of buildings completed in that year reached about 35%. Therefore, the country's annual cost for building leakage maintenance is quite staggering. [0003] The common measures taken to solve the problem of roof water leakage are to add waterproof membranes. There are many varieties of waterproof membranes, such as asphalt, rubber, chlorinated polyethylene, polyvinyl chloride, ethylene-vinyl acetate, etc. Bitumen waterproofing membrane is a waterproofing membrane that is still used in a certain range. However, due to the fact that this material is easy to soften and flow at high temperature, brittle and cracks at low temperature, and has no environ...
