Abstract

The invention discloses a water emulsion type plant adhesive and a preparation method thereof, belonging to the field of adhesives. The adhesive consists of styrene or methyl methacrylate, vinyl acetate, butyl methacrylate, butyl acrylate, iso-octyl acrylate, acrylic acid, crosslinking monomer, adhesion reinforcing monomer, emulsifier, initiator, tert-butyl hydroperoxide, buffer agent, pH regulator and deionized water; and through a seeded emulsion polymerization technology, the homopolymer of styrene or methyl methacrylate is synthesized firstly as seed, the pre-emulsion is dropwise added to the seed polymerization particles to synthesize a shell polymer, and finally a core-shell structure with a hard core and a soft shell is formed. After the film formation of the polymer particles, the initial adhesion is high, and the sticking of glass beads on an adhesive layer is facilitated; and moreover, the cohesion is great, thus no adhesive residue is transferred to the base fabric during the transfer of the plant particles, and the washing effect of the reflective fabric is improved.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a water-emulsified bead-planting adhesive. Background technique [0002] Adhesives for bead planting of reflective materials, most manufacturers are still using two-component solvent-based acrylic adhesives, this adhesive is a two-component pressure-sensitive adhesive system, which has high energy consumption, heavy environmental pollution, and poor construction environment for workers; some manufacturers have begun to try For water-based bead-planting glue, due to the insufficient cohesive energy of the water-based system, the residual glue will transfer to the cloth base with the beads, reducing the washing effect and brightness of the reflective cloth. Contents of the invention [0003] The technical problem to be solved in the embodiments of the present invention is to provide a water-emulsified bead-planting adhesive and its preparation method, which can significantly reduce energ...
