Polymer pre-paved waterproof coiled material

Abstract

The invention discloses a polymer pre-laid waterproof coiled material, and relates to the technical field of waterproof coiled materials. The polymer pre-laid waterproof coiled material comprises a polymer sheet and a polymer adhesive layer, and the polymer adhesive layer is formed on the polymer sheet. By adopting a water-based protective layer, on one hand, the main chain of an organic silicon rubber emulsion molecule is a -Si-O- bond, the organic silicon rubber emulsion molecule is a linear polymer taking a mono-valent organic group as a side group, and the organic silicon rubber has the widest use temperature range in all rubbers and has excellent ozone aging resistance, oxygen aging resistance, light aging resistance and weather aging resistance; on the other hand, the added fumed silica has extremely strong ultraviolet absorption and infrared light reflection characteristics, the aging resistance of a coating can be improved when fumed silica is added into the coating, in addition, silicon-alcohol bonds on the surface and calcium ions in concrete carry out a chemical reaction, the bonding between the pre-laid coiled material and the concrete is enhanced, and a synergistic bonding effect is achieved.

Description

technical field [0001] The invention relates to the technical field of waterproof coiled material, in particular to a polymer pre-laid waterproof coiled material. Background technique [0002] In the process of continuous improvement of my country's urbanization level, various "urban diseases" are problems that most cities must face. The development and utilization of urban underground space has become an effective way for various cities to solve this problem. Under such a background, my country's cities The development and utilization of underground space has entered a stage of rapid development since the 21st century. Over the past decade, the utilization of underground space has grown rapidly and achieved remarkable results. Large-scale development has exposed more and more waterproof problems of underground buildings. Underground waterproofing has risen to a position related to building safety and has attracted more and more attention from all sides. [0003] The pre-laid...

Problems solved by technology

Its main feature is that the preparation method of the silicon-containing unsaturated carboxylic acid modified butyl rubber is: make butyl rubber and unsaturated carboxylic acid in the presence of a free radical initiator, in a solvent and at a temperature of 60°C-80°C C under heat preservation reaction for 3 hours, add activated silicon dioxide, mix well, and obtain the solution of the silicon-containing unsaturated carboxylic acid modified butyl rubber. The disadvantage of this invention is that organic solvents are used in the production process, and the pollution is not environmentally friendly.

[0006] Chinese invention patent CN102604496B discloses a protective layer for pre-laying waterproof coils, a quick-drying and thin-coating type acrylic protective coating, mainly composed of water, cosolvent, acrylic emulsion, filler, quick-drying agent, porosity agent, and dispersant , wetting agent, defoamer, leveling agent, thickener, etc. Acrylic material itself is not weather-resistant, and usually loses its adhesion after ultraviolet aging, because if the construction period is delayed after the pre-laying coil is constructed, it will be exposed to ultraviolet rays and Under the action of wind and rain, the effect of bonding with the post-cast concrete will be lost, resulting in the scrapping of the entire waterproof system
