Problems solved by technology

However, in the actual application process, it is found that the surface tension of the polymer sheet after corona treatment will attenuate, which still cannot solve the problem of the risk of the pressure-sensitive adhesive layer detaching from the polymer sheet layer, and this This corona treatment method does not help to improve the dimensional stability of polymer waterproof membranes and the retention rate of heat aging tensile strength

Abstract

The invention relates to a primer, a polymer pre-laid waterproof coiled material and a preparation method, the polymer pre-laid waterproof coiled material comprises a base material layer, a primer layer, an adhesive layer and an anti-sticking layer which are sequentially stacked, and the raw material formula of the primer adopted by 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 an existing high-molecular pre-laid waterproof roll, the high-molecular pre-laid waterproof roll has the advantages that by using the specific primer, the degumming rate is greatly reduced in the using process; and meanwhile, compared with the existing high-molecular pre-paved waterproof roll, the high-molecular pre-paved waterproof roll disclosed by the invention also has excellent dimensional stability and tensile strength retention rate after high-temperature thermal aging.

Description

technical field [0001] The invention belongs to the technical field of waterproof coiled material, and in particular relates to a primer, a polymer pre-paved waterproof coiled material and a preparation method thereof. Background technique [0002] Compared with the traditional SBS asphalt-based waterproofing membrane, the polymer pre-paved anti-adhesive waterproofing membrane has the following advantages: 1) The waterproof layer is fully bonded to the concrete, forming a skin-like bond, realizing the fusion of the structure and the waterproofing layer, and preventing water channeling 2) Empty paving construction, low requirements on the base surface; 3) The construction process is safe and environmentally friendly, with fast construction speed and short construction period, and the application of single-layer polymer pre-laid anti-adhesive waterproofing membrane can meet the first-class waterproof requirements. Therefore, in recent years, pre-paved anti-adhesive waterproof ...
