Problems solved by technology

However, such products have major defects in terms of water resistance, durability, ability to adapt to the deformation of the base layer, and reliability of construction applications, especially the cases of engineering leakage caused by inferior "non-standard" materials are too numerous to enumerate. It has become one of the main reasons for the high leakage rate of domestic construction projects.

Abstract

The invention discloses a polyethylene polypropylene fiber high polymer waterproof rolling material for improving artificial weathering aging performance. The polyethylene polypropylene fiber high polymer waterproof rolling material is composed of the following components in parts by weight: 92.0-95.0 parts of linear low density polyethylene resin, 0.5-1.5 parts of titanium oxide, 0.1-0.5 part ofa dispersing agent and 5.0-8.0 parts of an active agent, wherein the active agent is prepared by the following steps: (1) carrying out steam explosion treatment, namely adding momordica grosvenori subjected to water extraction into a steam explosion tank to be treated; and (2) carrying out treatment of a high shear mixer, namely adding purified water in equivalent weight, treating by the high shear mixer, and drying, thereby obtaining the active agent.

Description

technical field [0001] The invention belongs to the technical field of building materials and petrochemicals, and in particular relates to a polyethylene polypropylene polymer waterproof coiled material for improving artificial weather aging performance. Background technique [0002] Polyethylene polypropylene waterproofing membrane belongs to the series of synthetic polymer waterproofing membranes. In addition to all the advantages of synthetic polymer membranes, its most prominent feature lies in the mesh structure on its surface, which makes it have its own unique The use of performance - cement bonding. Because the polymer composite coil can be directly bonded with cement, it will not be affected by the moisture content of the base during the construction process, and it can be constructed as long as there is no clear water. This is not available in other waterproof membranes. Due to the rough surface and high friction coefficient of the polymer composite coil, it can ...
