Abstract

The invention discloses composite impermeable cloth for a salt pond. The composite impermeable cloth consists of polyester industrial cloth, a polyvinyl chloride rubber modified films and pasty polyvinyl chloride coatings, wherein the pasty polyvinyl chloride coatings are adhered to two surfaces of the polyester industrial cloth; the polyvinyl chloride rubber modified films are attached to two sides surfaces of each pasty polyvinyl chloride coating through pressurization. The invention also provides a method for preparing the composite impermeable cloth for the salt pond. The method comprises the following steps: infiltrating and coating the pasty polyvinyl chloride coatings on the polyester industrial cloth, plastifying the polyester industrial cloth coated with the pasty polyvinyl chloride coatings at the high temperature of 180-240 DEG C, attaching the rubber modified films to the two side surfaces of a semi-finished product, and the like.

Description

technical field

[0001] The invention relates to a polyvinyl chloride composite material, in particular to an anti-seepage cloth applied to salt ponds. Background technique

[0002] Soil is permeable and seepage is a common natural loss phenomenon. In the salt lake industry and seawater salt production industry, the infiltration rate is one of the indispensable salt field process parameters, and it is the key data reflecting the quality of the salt field pool plate, which is directly related to the amount of salt produced. According to statistics, during the process of evaporating and concentrating the brine in the salt field, the brine loss is as high as 30% due to the leakage of the pool plate in the salt field, which seriously reduces the production efficiency of the salt field. At present, methods of anti-seepage in salt fields include clay mechanical compaction, plastic film bottoming and other methods. Clay has the characteristics of fine particles, strong plasticity,...
