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-wear-resistant flame-retardant waterproof coiled material and a preparation method and application thereof. The high-strength super-wear-resistant flame-retardant waterproof coiled material is prepared from recycled PVC and waste epoxy resin as raw materials, and appropriate ethylene-vinyl acetate copolymer, a nano flame retardant, an anti-aging agent, an antistatic agent and other auxiliaries are added in the production process; the high-strength super-wear-resistant flame-retardant waterproof coiled material is prepared through technologies of mixing, banburying, extruding, and calendaring together with glass fiber cloth. The anti-aging agent contains a heat stabilizer, an antioxidant and a light stabilizer and can weaken the ultraviolet ray and sunlight irradiation intensity, and the addition of the glass fabric can improve the tensile strength of the product, promote the adjustment of indoor climate, prevent moisture and mildew, prolong the service life, is easy to construct and has a very good application prospect.

Description

technical field [0001] The invention relates to the field of recycling and reuse of construction solid waste and waterproof materials, in particular to a high-strength super-abrasion-resistant and flame-retardant waterproof coiled material and its preparation method and application. Background technique [0002] With the improvement of people's requirements for quality of life, the requirements for anti-leakage of houses, tunnels and roads are also constantly increasing. Waterproof membrane is a flexible building material product that can resist external rainwater and groundwater leakage and can be rolled into rolls. It is the first barrier for waterproofing the entire project. [0003] Traditional waterproofing membranes include asphalt waterproofing materials and synthetic polymer waterproofing membranes. 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 temperat...
