Problems solved by technology

[0008] Polyethylene polypropylene waterproofing membrane is generally thin, so the penetration resistance is poor. Once there are sharp sand and pebbles left under the waterproof layer, polypropylene waterproofing membrane is easy to be pierced
Compared with coating film, its elasticity is small, and its adaptability to complex base is poor; compared with SBS modified asphalt membrane waterproof, its heat resistance is slightly worse; compared with SBS modified which has been developing steadily in recent years and occupies the leading position of waterproof material Compared with asphalt membrane, its construction temperature range of 5-25℃ is far less than that of SBS waterproof membrane.
In addition, polyethylene polypropylene fiber waterproofing membrane is not as plastic as SBS modified bitumen waterproofing membrane. If its thickness is above 1.0 mm, its flexibility will decrease, construction performance will decrease, and detailed node treatment is not easy to ensure waterproof quality.

Abstract

The invention discloses a polyethylene polypropylene fiber polymer waterproof rolling material with improved alkali-resistant stability. The polyethylene polypropylene fiber polymer waterproof rollingmaterial is prepared from the following components in parts by weight: 90.0 to 95.0 parts of linear low-density polyethylene resin, 0.5 to 1.5 parts of carbon black, 0.1 to 0.5 part of a dispersing agent and 5.0 to 10.0 parts of an activating agent, wherein the activating agent is obtained through a preparation method comprising the following steps: (1) pressurizing treatment: putting fructus momordicae grosvenori residue after water extraction into a high-pressure tank, pressurizing to 3kg / cm<2>, making the pressure be constant, keeping the constant pressure, and then instantly releasing thepressure; (2) high shear homogenizer treatment: adding a material obtained in the step (1) into purified water of which the weight is equal to that of thematerial, treating through a high shearing homogenizer, and drying, thus obtaining the activating 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 with improved alkali resistance and stability. 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 be di...
