Problems solved by technology

Although the cost of bitumen waterproofing membrane is low, its temperature stability is poor, it is easy to flow at high temperature, easy to be brittle at low temperature, and has a short service life
PVC waterproof membrane is a common thermoplastic polymer membrane. This membrane has good dimensional stability and low thermal expansion coefficient, but its physical properties will decrease rapidly with time.
[0004] Judging from the content of invention patents related to PVC waterproofing membranes in recent years, most of the patents simply compound PVC and polyester or modify the surface of PVC waterproofing membranes with asphalt and other polymer coatings. These two methods mainly contribute to improving the corrosion resistance, self-adhesiveness and antistatic properties of waterproof membranes, but fail to improve their strength and flame retardancy.
In addition, there are also some patents that have carried out more detailed research on the production process and production equipment of PVC waterproof coiled materials, but the process and equipment requirements are very complicated, which has increased the production cost of PVC waterproof coiled materials to a certain extent. Little practical significance for mass production

Abstract

The invention relates to a high-strength super-abrasion-resistant and flame-retardant waterproof coiled material and its preparation method and application. The high-strength super-abrasive and flame-retardant waterproof coiled material uses recycled PVC and waste epoxy resin as raw materials, and adds Appropriate ethylene-vinyl acetate copolymers, nano-flame retardants, anti-aging agents and antistatic agents and other additives are prepared by mixing, banburying and extrusion, and then co-calendering with glass fiber cloth. The anti-aging agent contains heat stabilizers, antioxidants and light stabilizers, which can weaken the intensity of ultraviolet rays and sunlight. The addition of glass fiber cloth can improve the tensile properties of the product, promote the adjustment of indoor climate, prevent moisture and mildew, and prolong the service life. , easy to construct, and has a good application prospect.

Description

Technical field [0001] The present invention relates to building solid waste recovery reuse and waterproof material, and therefore referring to a high-strength super-resistant flame retardant waterproof web and a preparation method thereof. Background technique [0002] As people improve their quality requirements, the requirements for prevent leakage of housing, tunnels and highways are also increasing. Waterproofing web is a canable curvature-shaped flexible building materials that can resist outside rainwater, groundwater leakage, is the first barrier for the entire project waterproof. [0003] Conventional waterproof web has asphalt waterproof materials and synthetic polymer waterproof coil. Although the asphalt waterproof coil is low, the temperature is poor, high temperature is easy to flow, low temperature and easy brush, and short use. PVC waterproof web is a common thermoplastic polymer web that has better dimensional stability and lower thermal expansion coefficient, bu...
