Abstract

The invention relates to an adhesive for wet paving of a macromolecular self-adhesive film waterproof coiled material and a preparation method of the adhesive. The adhesive comprises the following components in parts by weight: 50-60 parts of cement, 50-70 parts of filler, 60-65 parts of polyvinyl alcohol, 4-8 parts of a water-retaining agent, 6-10 parts of a thickening agent, 10-20 parts of quartz sand and 20-25 parts of master batch. Compared with the existing polymer self-adhesive film waterproof coiled material cement-based adhesive, the polymer self-adhesive film waterproof coiled material cement-based adhesive disclosed by the invention has higher adhesive performance, better base deformation adaptability and a double-waterproof function, the service life of the polymer self-adhesive film waterproof coiled material adhesive is prolonged, and the polymer self-adhesive film waterproof coiled material cement-based adhesive is particularly suitable for roof and underground waterproof engineering with large base change; and in addition, the raw materials are easy to obtain, the preparation process is simple and convenient, and the product is low in comprehensive cost and suitable for large-scale industrial production and wide application.
