Problems solved by technology

However, since EPDM belongs to non-polar and difficult-to-bond materials, the bonding problem of EPDM vulcanized waterproofing membranes has been difficult to popularize and apply. Although materials have made great technological progress, they still cannot fundamentally solve the above defects.
However, Document 1 cannot meet the technical requirements of its national mandatory product standard "Polymer Waterproof Material Part 1 Sheet (GB18173.1-2012)", and Document 2 has the disadvantages of high price and poor cost performance, which will affect the popularization and application.

Abstract

The invention relates to a production method of an ethylene propylene diene monomer self-adhesion water-resistant coiled material. The technical scheme is as follows: the method comprises the following steps: fully coating a composite modified butyl pressure-sensitive self-adhesion adhesive on a ethylene propylene diene monomer vulcanized water-resistant coiled material main body layer by using a hot-melt pressure-sensitive adhesive coating machine to form a composite modified butyl pressure-sensitive self-adhesion layer, coating an anti-adhesion barrier film on the composite modified butyl pressure-sensitive self-adhesion layer, and cutting the side of the anti-adhesion barrier film with a cutting device to arrange intermittent tear slots, thereby preparing the coiled material product. By arranging the ethylene propylene diene monomer vulcanized coiled material main body layer and the composite modified butyl pressure-sensitive self-adhesion layer, the product has dual water-resistant characteristic, and thus, has obviously higher water resistance; the product has the water-resistant function of full skin adhesion, implements the effective fusion and maximum permanent seal between the coiled material and base layer; and besides, the coiled material has high chemical corrosion resistance.

Description

technical field [0001] The invention relates to an EPDM waterproof coiled material, in particular to a production method of an EPDM self-adhesive waterproof coiled material. Background technique [0002] At present, the relatively mature polymer membranes in China mainly include EPDM rubber vulcanized waterproof membranes and PVC waterproof membranes, etc., especially EPDM rubber vulcanized waterproof membranes are internationally recognized as having the best aging resistance. Good waterproof membrane. However, since EPDM belongs to non-polar and difficult-to-bond materials, the bonding problem of EPDM vulcanized waterproofing membranes has been difficult to popularize and apply. Although materials have made great technological progress, they still cannot fundamentally solve the above-mentioned defects. This defect is determined by the structural characteristics of the material itself, and is an inherent defect that is difficult to solve. In recent years, some public lit...
