Abstract

The invention discloses a hydrophilic anti-adherent film. The hydrophilic anti-adherent film is characterized by comprising an anti-adherent layer and a hydrophilic layer, wherein the hydrophilic layer can ensure that water is rapidly and uniformly distributed on the hydrophilic layer; preferably, the hydrophilic layer is prepared from the following raw materials in parts by weight: 60.0-80.0 parts of high-density polyethylene, 5.0-20.0 parts of polyvinyl alcohol or ethylene-acetic acid vinyl ester copolymerization resin and 5.0-25.0 parts of low-density polyethylene. The hydrophilic layer of the anti-adherent film provided by the invention has polarities and a good soaking effect to water; when the hydrophilic layer is in contact with water, the hydrophilic layer can be rapidly soaked and spread to form a layer of water film; and when a high-temperature self-adherent material is in contact with a silicon resin surface of the anti-adherent film, the water film on the back surface can absorb lots of heat to evaporate, thus the temperature of the silicon oil surface is rapidly reduced and does not exceed 100 DEG C all the time, namely the temperature of the anti-adherent layer is substantially reduced, and a 'silicon transfer' phenomena of silicon resin can be effectively avoided, so that initial viscosity of a self-adherent coiled material is not affected.

Description

technical field [0001] The invention relates to an anti-adhesive film for waterproof rolls, in particular to a hydrophilic anti-adhesive film for self-adhesive waterproof rolls and a preparation method thereof. Background technique [0002] At present, there are three main categories of waterproofing membranes sold in the Chinese market, namely: 1. Modified asphalt waterproofing membranes; 2. Polymer plastic sheets; 3. Rubber waterproofing membranes. Among them, modified asphalt waterproofing membrane occupies a dominant position in the application, with an output of 400 million square meters in 2010, while self-adhesive membrane accounts for 30%, and it grows at a rate of 50% every year. There are three construction methods for these membranes in the general application engineering construction process, namely: 1. Heat the molten asphalt with a gasoline blowtorch and paste it on the base layer, such as: modified asphalt waterproof membrane; 2. Use cold adhesive Paint and p...
