Abstract

Belonging to the field of adhesive preparation, the invention discloses a water-emulsion plant adhesive and its preparation method. The adhesive is formed through polymerization of a monoene hard monomer, a monoene soft monomer, a carbonyl functional monomer, an acrylic crosslinking monomer, an emulsifier, a pH value conditioning agent, an initiator, deionized water, a chain transferring agent, aplasticizing agent and a thickening agent. The vitrification temperature Tg of the adhesive is 15-65DEG C. Compared with current solvent type bicomponent plant adhesives, the adhesive provided in theinvention has the advantages of safety and environmental protection, as well as higher microbead transfer rate.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a water-emulsion type plant adhesive and a preparation method thereof. Background technique [0002] At present, in the field of reflective materials, most manufacturers of plant adhesives are still using two-component solvent-based acrylic adhesives. Most of the adhesives use organic amines as curing agents. A large amount of solvents are directly discharged during use of the adhesives. High consumption; in the composite peeling stage, the control of the transfer rate of microbeads is not easy to control, resulting in insufficient reflectance of the final product, and due to the use of amine curing agents, the curing temperature is above 120 ° C, which increases the risk of operation and the performance of the unit product. consumption. Contents of the invention [0003] The embodiment of the present invention provides a water-emulsion type plant adhesive and its preparation method, ...
