Problems solved by technology

This method of physical blending is cumbersome to operate. First, polyacrylate resins with different Tgs must be synthesized. During blending, the performance of the blend may be different due to the inconsistent conversion rate of different batches of monomers.

Abstract

The invention discloses a composite transfer adhesive for a high-brightness reflective fabric. The composite transfer adhesive is prepared from raw materials comprising the following components in parts by weight: 50-70 parts of acrylate soft monomer, 10-40 parts of acrylate hard monomer, 3-12 parts of acrylate functional monomer, 0.2-1 part of initiator and 180-190 parts of solvent. The invention also discloses a preparation method of the composite transfer adhesive. The composite transfer adhesive has the beneficial effects that only low-toxicity ethyl acetate is adopted to serve as a solvent; the composite transfer adhesive for the high-brightness reflective fabric is synthesized by adopting a graft copolymerization method, so that high initial stickness is kept, and the holding power is greatly improved; the rubbing resistance and washing resistance applied to the high-brightness reflective fabric are far higher than those of random copolymer. A method for adding the initiators in batches is adopted, and the influence on the product performance in a traditional dripping mode due to the inconsistent dripping speed is avoided.

Description

technical field [0001] The invention relates to a transfer composite adhesive for high brightness reflective cloth and a preparation method thereof. Background technique [0002] High-gloss reflective fabrics can be widely used in public security, fire protection, transportation, railways, sanitation, coal mines, and personal safety and protective equipment. They are usually composed of three parts: high refractive index glass beads, adhesives, and substrates. Among them, the adhesive is the key basic raw material of the reflective material, and is the adhesive between the glass beads and the substrate, and requires good film-forming properties, softness, washing resistance and wear resistance. [0003] At present, the reflective fabric market mainly uses two systems of adhesives, one is polyacrylate system adhesives, and the other is polyurethane system adhesives. However, according to the use requirements of high-brightness reflective cloth, acrylic adhesives can fully me...
