Abstract

The invention relates to an aqueous adhesive used for surface flocking of a sheet metal, especially relates to a water-borne adhesive used for steel plate flocking and its preparation method. The method comprises the following steps: adding a polymerization emulsion and filling materials into a container, stirring and adding an antifoaming agent, a mildew-resistant bactericide, a wetting agent and a thickening agent, continuously stirring; decelerating the stirring speed and adding a tackifier, obtaining the water-borne adhesive used for steel plate flocking. The invention has the advantages of long storage life, moderate flexibility and high adhesive strength, and the adhesive provided in the invention has high strength of adhesion stress to sheet metal and nylon fine hair and good waterproof performance, so that the adhesive can ensure the usage of the flocking steel plate in a plurality of environments.

Description

Technical field [0001] The invention relates to a water-based adhesive applied to flocking on the surface of a metal sheet, in particular to a water-based adhesive for flocking of steel plates and a preparation method thereof. Background technique [0002] Flocking steel plate is a high-performance material made of continuous electrostatic flocking on raw material coils. As a relatively novel flocking product, flocking steel plate has unique and excellent properties. The flocking steel plate can be made of hot-dip galvanized steel plate, electro-galvanized steel plate, color steel plate, stainless steel plate, aluminum alloy plate and other materials as the substrate, and any desired pattern can be planted on the pile surface. The production of this planting steel plate has many requirements for the adhesive: first, the adhesive used must have excellent substrate adhesion, and it will not peel off like foam plastic and glass fiber support materials. , The adhesive is required t...
