Environment-friendly composite waterproof membrane and production method thereof

Abstract

The invention discloses an environment-friendly type composite waterproof coiled material. The environment-friendly type composite waterproof coiled material takes polyester filament cloth as a matrix, wherein the two surfaces of the matrix are immersed with macromolecular polymer emulsion prepared from acrylate emulsion, a film forming auxiliary agent, a thickening agent, a mildew-proof agent, a de-foaming agent, wollastonite powder, pigment paste and the like; and the polyester filament cloth is used as a waterproof material layer and is dried. The polyester filament cloth with good mechanical properties is used as the matrix, so that the tensile strength is high, the linear expansion coefficient is small and the low-temperature flexibility is good; the macromolecular polymer emulsion, which is scientifically prepared, is used as the waterproof material layer and has the advantages of strong impermeable ability, great friction coefficient, no toxicity and wide applicable temperature range; the produced environment-friendly type composite waterproof coiled material has light self weight, is relatively flexible and smooth and is easy to lay and stick in a construction process, so that the limitation that the construction of an existing waterproof coiled material requires low moisture content of a building base layer is solved; and the coiled material has the advantages of good stability, strong deformation adaptation capability, good chemical stability, corrosion and mildewing resistance, ozone resistance and long service life. The environment-friendly type composite waterproof coiled material is environment-friendly and nontoxic so that the material can be directly used for drinking water projects.

Description

technical field [0001] The invention relates to waterproof materials, in particular to an environment-friendly composite waterproof coiled material used in building waterproof engineering construction. Background technique [0002] The waterproof material products made by impregnating asphalt or polymer waterproof materials on the carcass are provided in the form of rolls and are called waterproof rolls. Building waterproof membranes are mainly used in building walls, roofs, tunnels, roads, landfills, etc., to resist external rainwater and groundwater leakage. The domestic waterproofing membrane is mainly modified asphalt waterproofing membrane (SBS), and its application proportion in engineering is as high as more than 60% of the waterproofing membrane market. Modified asphalt waterproofing membrane (SBS) is heavy in weight, serious environmental pollution in the production process, low tear strength of the finished product, easy to be damaged in exposed use, poor anti-agi...

AI Technical Summary

Problems solved by technology

Modified asphalt waterproofing membrane (SBS) is heavy in weight, serious environmental pollution in the production process, low tear strength of the finished product, easy to be damaged in exposed use, poor anti-aging ability, short service life; and because it is not environmentally friendly, it also pollutes when used Environment, during construction, there is a requirement for the moisture content of the building base, and the construction is inconvenient
