Problems solved by technology

[0002]Adhesive is one of the raw materials that must be used in the existing flocking process. Most of the existing flocking adhesives are water-based acrylic and acetic acid However, the existing water-based adhesives need to be dehydrated and solidified in the process of flocking processing, and the requirements for the drying process are relatively strict. During the curing process, the drying curve and drying temperature need to be strictly controlled, and the fastness is not good. high defect

Abstract

The invention discloses an adhesive for flocking and a flocking process. The adhesive for flocking comprises the following raw materials in parts by weight: 10-50 parts of an ethylene-vinyl acetate copolymer; 70-100 parts of a thermoplastic polyurethane elastomer; 3-15 parts of a terpene resin; 2-8 parts of calcium carbonate; 1-5 parts of dimethyl phthalate; 3-8 parts of a viscosity modifier; and 0.5-3 parts of an antioxidant. The adhesive for flocking can effectively improve the flocking fastness in the flocking processing process.

Description

technical field [0001] The invention belongs to the technical field of flocking, in particular to an adhesive for flocking and a flocking process. Background technique [0002] Adhesive is one of the raw materials that must be used in the existing flocking process. Most of the existing flocking adhesives are water-based acrylic and acetic acid water-based adhesives, but the existing water-based adhesives are used in The flocking process requires dehydration and curing, and the drying process is relatively strict. The curing process requires strict control of the drying curve and drying temperature, and has the disadvantage of low fastness. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes an adhesive for flocking and a flocking process, and the adhesive for flocking can effectively improve the flocking fastness in the flocking process. ...
