Abstract

The invention relates to a bonding agent, and discloses a preparation method of PVC (polyvinyl chloride) wood grain thin film bonding glue by aiming at solving the problems that in the prior art, thegeneral initial adhesion of an acrylate bonding agent is low, and the bonding intensity is poorer, so that a Plastic wood floor and a PVC wood grain thin film can easily peel. The preparation method comprises the following steps of (1) material preparation; (2) pre-emulsification; (3) pre-polymerization; (4) copolymerization; (5) blending. The types and the composition of comonomers are optimized;an emulsified rosin thickening agent is added; the process steps are simple; the reaction process is stable and controllable; the prepared product can be crosslinked and cured at normal temperature;the stability is good; the layering cannot easily occur; the bonding force is strong; the plastic wood floor and the PVC wood grain thin film cannot easily peel; higher popularization values are realized.

Description

technical field [0001] The invention relates to an adhesive, in particular to a method for preparing PVC wood grain film adhesive. Background technique [0002] Wood-plastic composite floor is a kind of wood (wood cellulose, plant cellulose) as the basic material, thermoplastic polymer materials (PE, PVC plastic) and processing aids, etc., mixed evenly and then heated and extruded by mold equipment The high-tech green environmental protection material has the properties and characteristics of wood and plastic, and can replace wood. [0003] One of the plastic-wood composite floor surfaces is compounded with a PVC film with printed wood grains, which needs to be coated with a layer of adhesive on the surface of the plastic-wood composite floor during production. The adhesive currently used is a commercially available two-component adhesive, which needs to be mixed with component A (main agent) and component B (curing agent) during use, which is very inconvenient to use. In ...
