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.

Description

technical field [0001] The invention relates to the technical field of waterproof materials, in particular to an adhesive for wet-laying of polymer self-adhesive film waterproof rolls and a preparation method thereof. Background technique [0002] In waterproofing engineering, polymer self-adhesive waterproofing membrane is more and more popular and widely used because of its high tensile force, excellent elongation, and strong ability to adapt to changes in the base layer. At present, the adhesives used for the polymer self-adhesive film waterproofing membrane are all cement-based adhesives. When the base layer is deformed, the rigid lapping edge adhesive is easy to crack, resulting in the waterproofing of the polymer self-adhesive film. The membrane is prone to leakage, which leads to the failure of the entire waterproofing project. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior...
