Problems solved by technology

However, due to the shortcomings of acrylate adhesives in terms of wear resistance, hand feeling, and wet fastness, traditional acrylate adhesives generally need to be baked and cross-linked at a high temperature of 140-150°C to cure, which consumes a lot of energy and cannot be used. Meet energy saving needs

Abstract

The invention discloses an adhesive for electrostatic flocking, wherein the adhesive comprises, by mass, 5-25 wt% of tetramethyl tetravinyl cyclotetrasiloxane, 0.8-2.5 wt% of dodecylbenzene sulfonic acid, 1-10 wt% of a KH550 silane coupling agent, 1.6-5 wt% of a nonionic emulsifier XP80, 10-15 wt% of methacrylate, 10-15 wt% of butyl methacrylate, 0.5-2 wt% of N-hydroxymethyl acrylamide, 0.5-2 wt%of acrylic acid, 0.5-1 wt% of lauryl sodium sulfate, 0.4-1 wt% of ammonium persulfate, 1-10 wt% of nanometer zinc oxide powder and 10-55 wt% of deionized water. The invention further discloses a preparation method of the adhesive for electrostatic flocking. According to the invention, the adhesive has the characteristics of good adhesion to fluff and cloth, high adhesion strength and long storagelife, can be sealed and stored at a normal temperature for more than one year, is used in an electrostatic flocking process to endow textiles with good wear resistance, good hand feeling and good color, and enables products to have the functions of ultraviolet resistance, sterilization, hydrophobicity and the like.

Description

technical field [0001] The invention belongs to the technical field of electrostatic flocking fabrics, in particular to an adhesive for electrostatic flocking and a preparation method thereof. Background technique [0002] Electrostatic flocking consists of three parts: substrate, adhesive and fluff, commonly known as "three major pieces". Among them, the adhesive on the surface of the substrate is the key to the quality of electrostatic flocking products, and its performance directly determines the quality of flocking products. Flocking fastness and hand feel are good or bad. [0003] Flocking adhesives are divided into two types: emulsion type and solvent type. The usage of the former accounts for more than 90% of the flocking adhesive. Flammable and toxic due to volatilization, can be diluted with water, easy to operate and so on. Solvent-based adhesives are mainly used on metal, rubber and other substrates. However, in recent years, due to environmental protection issu...
