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 high molecular waterproof roll with good alkali-resistant stability. The roll is prepared from the following components in parts by weight: 90.0-95.0 parts of linear low density polyethylene resin, 0.5-1.5 parts of carbon black, 0.1-0.5 part of a dispersant and 5.0-10.0 parts of an activator. The activator is prepared from the following methods: (1) carrying out steam explosion treatment, namely putting water extracted momordica grosvenori residues in a steam explosion tank to treat; and (2) carrying out high shear homogenizer treatment, namely adding pure water equal in weight into the material obtained in the step (1), carrying out treatment by a high shear homogenizer, and drying the mixture to obtain the activator.

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 good 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 direct...
