Flame-retardant thermoplastic polyolefin (TPO) waterproof material and construction method thereof

Abstract

The invention relates to the technical field of flame-retardant waterproof materials, and in particular to a flame-retardant thermoplastic polyolefin (TPO) waterproof material and a construction method thereof. The flame-retardant TPO waterproof material is excellent in adhesion, strong in durability, good in flame retardance, safe and environment-friendly. An emulsion is an aqueous system, is excellent in performance, and is environment-friendly; the roll coating construction of the emulsion on a TPO waterproof coiled material is convenient and safe. Compared with the conventional flame-retardant TPO waterproof material on the market, the flame-retardant TPO waterproof material has the advantages of low cost, good flame-retardant performance, environment friendliness, good durability, convenience in construction, safety, environment protection and the like, and has a quite great application value. In the actual application, the flame-retardant TPO waterproof material has the integrated characteristics of ageing resistance, high tension strength, large elongation, convenience in construction, no pollution and the like, and is quite applicable to serving as a waterproof layer for a light energy-saving roof; the product can be constructed on a wet roof, and a protection layer is not needed by an exposed part.

Description

technical field [0001] The invention relates to the technical field of flame-retardant waterproof materials, in particular to a flame-retardant TPO waterproof material and a construction method thereof. Background technique [0002] TPO waterproof material is thermoplastic polyolefin waterproof membrane, which is made of petroleum resin and ethylene, acetic acid, vinyl resin as base material, adding antioxidant, anti-aging agent, softener, and the surface is attached with fabric fiber and aluminum film. The new type of waterproof membrane is a new material that has become popular in the United States and Europe in recent years, and has gradually occupied an important position. The physical properties of this material meet the requirements of "Polymer Waterproof Materials" (GB18173-2000). TPO waterproof membrane The material combines the performance advantages of EPDM and PVC. It has the weather resistance and low temperature of the former and the weldability of the latter. T...

Problems solved by technology

[0002] TPO waterproof material is thermoplastic polyolefin waterproof membrane, which is made of petroleum resin and ethylene, acetic acid, vinyl resin as base material, adding antioxidant, anti-aging agent, softener, and the surface is attached with fabric fiber and aluminum film. The new type of waterproof membrane is a new material that has become popular in the United States and Europe in recent years, and has gradually occupied an important position. The physical properties of this material meet the requirements of "Polymer Waterproof Materials" (GB18173-2000). TPO waterproof membrane The material combines the performance advantages of EPDM and PVC. It has the weather resistance and low temperature of the former and the weldability of the latter. This material is different from traditional plastics. It shows high elasticity of rubber at room temperature, and can be like Therefore, this material has good processing performance and mechanical properties, and has high-strength welding performance. However, the TPO membrane itself is not flame-retardant. When using it to make a single-layer roof, residents setting off fireworks and firecrackers will make the roof Fire will cause loss of life and property. The common method of flame retardant TPO waterproof membrane at this stage is to add some inorganic or organic flame retardants during extrusion molding. However, the addition will have a certain impact on its performance. Tensile strength and elongation at break will decrease, and the cost is high, so it is not suitable for promotion
