Thermoplastic polyolefin-like waterproof material and preparation method thereof

Abstract

The invention provides thermoplastic polyolefine waterproofing material and a preparation method thereof. The waterproofing material takes warp-knitting terylene cloth (1) as base cloth, a surface course (4) is coated on the upper side surface of the base cloth (1), and a performance improvement layer (2) and a bottom layer (3) are orderly coated on the lower side surface of the base cloth (1). The thermoplastic polyolefine waterproofing material of the invention has good processing performance and mechanical performance and the recovery and reuse performance which the EPDM does not possess, can realize the body welding, contain no plasticiser in the auxiliary materials, have no problem of getting brittle due to the migration of the plasticizer, have the comprehensive characteristics of large tensile strength, good puncture resistance, strong ultraviolet resistance, smooth surface, high reflectivity, pollution resistance and so on, also have the characteristics of easy processing, weldability, convenient construction and complete recovery during the engineering application, and is the novel green environmental protection waterproofing material.

Description

technical field [0001] The invention relates to a waterproof material, in particular to a waterproof material mainly composed of thermoplastic polyolefins. Background technique [0002] With the popularization and development of various modern buildings and related technologies, the demand for waterproof materials in the field of construction engineering is increasing, and the quality requirements for them are getting higher and higher. Residential construction is one of the important factors for the growth of demand for waterproof materials, and roof maintenance and building renovation projects will also become another huge market space for waterproof materials. [0003] At present, in various waterproof materials at home and abroad, polymer-based materials are used, mainly EPDM, polyvinyl chloride (PVC), chlorinated polyethylene (CPE), chlorinated polyethylene Ethylene-rubber blends, rubber-plastic blends and recycled polyethylene (PE) geomembranes, etc. [0004] Thermop...

AI Technical Summary

Problems solved by technology

[0005] However, said TPO material also has certain deficiencies, such as: low tensile strength, generally only 20Mpa; especially its poor dimensional stability after the finished product, close to and exceeding 1.5%, therefore, it needs to be modified to meet the needs of waterproof materials

However, waterproof materials made of EPDM, chlorinated polyethylene-rubber blends, rubber-plastic blends, and reclaimed rubber are prone to aging, and carbon black reinforcement is generally required during processing. , so the environmental pollution is serious; and the waterproof materials made of polyvinyl chloride (PVC) and chlorinated polyethylene (CPE) also have poor aging performance, especially the need to add plasticizers, which may become brittle due to the migration of plasticizers The problem
