Problems solved by technology

Self-adhesive waterproof membranes generally include self-adhesive polymer modified bitumen waterproof membranes and waterproof membranes with self-adhesive layers (divided into asphalt-based membranes and polymer membranes). Currently, waterproof membranes with self-adhesive layers are on the market. Most of the self-adhesives used in materials are made of polymer-modified asphalt base. Although the base asphalt has been modified by high-molecular polymers, the performance meets the construction and waterproof requirements, but it is still far from meeting the requirements of construction and construction in terms of durability. Requirements for the same life expectancy, and asphalt-based self-adhesives are not conducive to environmental protection

Abstract

The invention provides an environment-friendly high-strength waterproof coiled material self-adhesive. The SBS thermoplastic elastomer of the present invention can increase the toughness and elasticity of the system; the compatibility between chlorinated paraffin and SBS is good, can reduce the glass transition temperature of the system, and reduce the processing temperature; the carbon five resin in the tackifying resin has good tackifying properties and heat resistance, can increase the viscosity of the system and widen the construction temperature; the mixture of rosin resin and terpene resin is used as a tackifier to improve the adhesion of the system; the addition of antioxidants improves the oxidation resistance of the system, and the present invention The technical solution has the advantages of simple production without special production equipment; reasonable process and simple and easy raw material addition process. The self-adhesive of the present invention is light yellow in shape, has extremely high peel strength and shear strength at room temperature, has excellent adhesion to various polar and non-polar materials, has high performance, and is environmentally friendly. Simple, can be used for low temperature coating at 120°C, and is energy-saving and environmentally friendly, and can be widely used in engineering construction.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to an environment-friendly self-adhesive adhesive for high-strength waterproof coiled materials. Background technique [0002] Since the 1990s, self-adhesive waterproof membrane, as a new type of building waterproof material, has rapidly become popular in my country's industrial and civil construction, construction, It has been popularized and applied in subway tunnels, bridge deck waterproofing and other fields. Self-adhesive waterproof membranes generally include self-adhesive polymer modified bitumen waterproof membranes and waterproof membranes with self-adhesive layers (divided into asphalt-based membranes and polymer membranes). Currently, waterproof membranes with self-adhesive layers are on the market. Most of the self-adhesives used in materials are made of polymer-modified asphalt base. Although the base asphalt is modified by high-molecular polymers, the performance meets the con...
