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 type high-strength waterproof coiled material self-adhesive. A SBS thermoplastic elastomer can increase toughness and elasticity of a system; chlorinated paraffin and SBS have good solubility, the glass transition temperature of the system is reduced, and the processing temperature is reduced; C5 resin in tackifying resin has good viscosifying capability and heat resistance, so the viscosity of the system is increased and the construction temperature is widen; rosin resin and terpene resin are mixed into an adhesion agent for cooperatively improving the anchoring strength of the system; an anti-oxidant is added for improving oxidation-resistivity of the system. The self-adhesive is advantageous in that: the production is simple, special production equipment is not needed; the technology is reasonable, and the raw material adding operation is concise and easy. The self-adhesive is light yellow, and peeling intensity and shearing intensity are extremely high at normal temperature; the self-adhesive has excellent anchoring strength for various polar and nonpolar materials, and has high performance and excellent environmentally friendly characteristics; the production technology is simple, and the self-adhesive can be used for coating at a low temperature 120 DEG C; the self-adhesive has the advantages of energy saving and environmental protection, and can be widely applied to 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...
