Problems solved by technology

The existing adhesive used for the self-leveling bonding of the decorative layer and the cushion layer is polymer glue, which is synthesized and emulsified by polymer emulsion and liquid rosin + solid rosin. The production process of this polymer glue is relatively complicated and the production process is cumbersome. , requires heating and melting, emulsification, cooling and other production steps, and the equipment also needs to use a reactor, and in the process of production and use, the volatilization of organic solvents will also have a certain impact on the environment, which directly limits the glue. widely produced and used

Abstract

The invention provides a water-based environment-friendly adhesive suitable for adhesion between a ground decoration layer and a cushion layer. The adhesive is prepared from following components by weight through evenly mixing: 35%-60% of an acrylic resin emulsion, 10%-50% of a tackifying resin emulsion and 2%-10% of a plasticizer, wherein the acrylic resin emulsion is one or more of a styrene-modified acrylic resin emulsion, a fluorine-modified acrylic resin emulsion, a polyurethane acrylic resin emulsion and a silicone-modified acrylic resin emulsion which have the glass transition temperature ranging from subzero 30 DEG C to 0 DEG C, the solid content percentage ranging from 57wt% to 75wt% and the molecular weight ranging from 100,000 to 500,000; the tackifying resin emulsion is one or more of a petroleum resin emulsion, a terpene resin emulsion and a rosin resin emulsion which have the softening temperature ranging from 20 DEG C to 80 DEG C, the solid content percentage ranging from 35% to 55% and the molecular weight ranging from 2,000 to 3,000; the plasticizer is one or more of a benzoate plasticizer, a phthalic acid ester plasticizer, a polyester plasticizer and a polyol ester plasticizer. The adhesive has good initial adhesion and wonderful flexibility, can be uncovered and adhered repeatedly and can be produced with the simple production technology.

Description

technical field [0001] The present invention relates to an adhesive, in particular to an adhesive used for bonding between a floor decoration layer and a cushion layer, and more particularly to a water-based, environmentally friendly adhesive that is suitable for bonding between a floor decoration layer and a cushion layer and is easy to prepare. adhesive. Background technique [0002] Self-leveling is a ground construction technology. It is a liquid substance mixed with cementitious materials, fine aggregates and additives and water. After pouring into the ground, this substance can flow along the ground according to the unevenness of the ground and smooth the ground. Self-levelling, and quickly dry and solidify to form a smooth, flat, seamless new base. Since the cushion self-leveling mortar can provide a suitable, flat, smooth and strong bedding base for uneven bases, it has developed rapidly in the field of decoration in recent years. After leveling, cover a decorative...
