preparation example Construction

[0029] The preparation method of acrylate solid repositionable adhesive comprises the following steps:

[0030] (1) Mixing: mix the acrylate monomer, unsaturated acid, functional monomer, special monomer, crosslinking agent and initiator uniformly by weight to obtain a mixture;

[0031] (2) The first stage of reaction: heat the mixture obtained in step (1) and maintain it in the temperature range of 80-90°C, and when the mixture becomes viscous, cool down to 50-70°C and keep it warm for 2 hours;

[0032] (3) Second stage reaction: heat the mixture obtained in step (2) to a temperature range of 150-180°C for reaction, stop the reaction when it reaches a fluid state, and the reaction time is 40-45 minutes to obtain a fluid polymer .

[0033] (4) Solidification: Cool the fluid polymer obtained in step (3) to below minus 70° C., the fluid polymer solidifies into a solid state, and obtains an acrylate solid repositionable adhesive.

[0034]It completely solves the problem of defo...

Abstract

The invention discloses an acrylic ester solid restickable adhesive and a preparation and coating method thereof. The acrylic ester solid restickable adhesive is prepared from the following raw materials in parts by weight: 60-95 parts of acrylic ester monomer, 0-6 parts of unsaturated acid, 0-6 parts of functional monomer, 1-20 parts of special monomer, 0.5-3 parts of an initiator and 0.1-1 partof a crosslinking agent. The preparation method of the acrylic ester solid restickable adhesive comprises the following steps of (1) mixing; (2) first-stage reaction; (3) second-stage reaction; and (4) solidification. The coating method of the acrylic ester solid restickable adhesive comprises the following steps that (1) the acrylic ester solid restickable adhesive is heated to 120-350 DEG C to become fluid by using a hot melting box; and (2) a base material is coated with the acrylic ester solid restickable adhesive at the fluid state obtained in the step (1), and the adhesive is solidifiedat the room temperature.

Description

technical field [0001] The invention belongs to the field of polymer material technology and hot melt adhesive coating, and specifically relates to an acrylate solid repositionable adhesive and a preparation and coating method thereof. Background technique [0002] Re-stickable notes are sticky notes that can be pasted repeatedly. Currently, re-stickable notes are emerging in China. The disadvantages of known solvent repositionable adhesives are obvious, that is, they are not very environmentally friendly (solvents are mostly harmful). Solvent-based adhesives pollute the environment very seriously. With the improvement of people's environmental awareness and the establishment and improvement of related laws, the application of solvent-based adhesives has been banned and declined rapidly. The manufacturer produces equipment, develops water-based glue, and creates a re-attachable manufacturing model with Chinese characteristics; the water-based pressure-sensitive removable ad...
