WIPO Patent Application WO/2023/077901

A1

The present invention relates to a primer, and a polymer pre-laid waterproof roll thereof and a preparation method. The polymer pre-laid waterproof roll comprises a base material layer, a primer layer, an adhesive layer and an anti-sticking layer which are sequentially stacked. A raw material formula of the primer used in the primer layer comprises a first emulsion and a second emulsion, the first emulsion is one or a combination of more of a butadiene-acrylic acid copolymer emulsion and a butadiene-methacrylic acid copolymer emulsion, and the second emulsion is rubber latex. Compared with the existing polymer pre-laid waterproof rolls, the polymer pre-laid waterproof roll in the present invention has a greatly reduced degumming rate in the using process by using the specific primer; moreover, compared with the existing polymer pre-laid waterproof rolls, the polymer pre-laid waterproof roll in the present invention also has excellent dimensional stability and tensile strength retention rate after high-temperature thermal aging.
