Abstract

The invention relates to a treating agent used for a waterproof coiled material, in particular to a base course treating agent used for a self-adhesive waterproof coiled material. The base course treating agent comprises the following components in part by mass: 60 to 70 parts of polymer emulsion, 25 to 30 parts of water, 5 to 8 parts of thickening agent, 3 to 5 parts of pigment, 0.3 to 0.6 part of light stabilizer, and 2 to 3 parts of antifoaming agent. The base course treating agent solves the problems of long drying time, low peeling strength, low heat resistance, low cryogenic property, high VOC content and the like of common bituminous base course treating agents, and has the advantages of short surface drying time, high peeling strength, high cryogenic property, environmental protection, non-toxity and the like.

Description

Technical field [0001] The invention relates to a treatment agent for waterproof coiled materials, in particular to a base layer treatment agent for self-adhesive waterproof coiled materials. Background technique [0002] Self-adhesive waterproof membrane is a new type of waterproof material with great development prospects. The application in our country began in the early 1990s, and it has just risen in the country and is in the ascendant. This kind of coil has the characteristics of water impermeability, low temperature flexibility, anti-deformation performance and good self-healing properties, and is easy to construct, which can increase the laying speed and accelerate the progress of the project. It has obtained a good waterproof effect and has been praised by construction, design and construction units. [0003] However, the base treatment agents supporting self-adhesive waterproof membranes are generally solvent-based or water-emulsion asphalt base treatment agents, which ...
