Abstract

The invention relates to the technical field of adhesives, solves the problem of using low solid content solvent-based composite adhesive in traditional reflective cloth, provides a preparation methodof a high solid content low viscosity acrylic resin adhesive and its application on a reflective cloth. The preparation method comprises the following steps: adding acrylate soft monomer, hard monomer, functional monomer, part by weight of organic solvent and part by weight of initiator into the bottom of a reaction kettle, heating to 78-85 DEG C, reacting for 1-2 hours, making the remaining initiator into initiator solution by using the part of the remaining organic solvent, and continuously dropping into the reaction kettle for a dropping time of 3-5 hours, controlling the temperature to 76-83 DEG C, keeping the temperature for 2-3 hours, adding the remaining organic solvent into the reaction system, adding the modified acrylate oligomer, and cooling to 50-60 DEG C and obtaining the acrylate adhesive with high solid content and low viscosity and the solid content of the obtained adhesive can reach more than 50%, and the adhesive has low viscosity characteristics at the same time.

Description

technical field

[0001] The invention relates to the technical field of adhesives, in particular to a method for preparing acrylic resin adhesives with high solid content and low viscosity. Background technique

[0002] Reflective cloth is to fix the glass beads on the fabric with adhesive, and use the optical principle of refraction and reflection in the glass beads and then return to reflection. At present, the reflective fabrics sold on the market are basically composed of base fabrics, adhesives, reflective layers, bead layers, etc., among which adhesives are important key basic raw materials.

[0003] Due to the characteristics of easy synthesis, good durability, good low temperature performance, low toxicity, and wide bonding surface, polyacrylate adhesives can meet the requirements for the use of luminescent materials. Since the acrylic adhesive for reflective cloth is the key raw material of reflective cloth, and it has certain commonality with commonly used acrylic ...
