Problems solved by technology

[0002] The application of high-toughness and environment-friendly peelable adhesives is very common, and has been widely used in aerospace, aviation, machinery, electronics, medical and other fields, but in use, there are problems such as poor toughness, high brittleness of cured products, poor impact resistance and vibration resistance. , easy to crack and other defects, as a structural adhesive, it must be modified and toughened to meet its special technical requirements
At present, the peelable glue on the market has the following disadvantages: (1) The peelable glue on the existing market contains volatile solvents, which will affect the performance of the scraper, the working environment, and the length of curing time, the process is complicated, and it will affect the touch screen sensor function. The base material on the block is corroded; (2) It will remain when peeling off, and there will be residual glue, which needs to be wiped with a solvent, which is mainly due to its poor toughness; (3) The peelable glue is more toxic, not only the solvent is volatilized, In addition, the used peelable rubber waste cannot be degraded and becomes a pollutant
Invention application "A Protective Elastic Peelable Blue Glue and Its Preparation Method" (Application No.: 201510438687.1) The product prepared uses a plasticizer, which is difficult to degrade and is not environmentally friendly

Abstract

The invention discloses a high-toughness environment-friendly peelable adhesive and a preparation method thereof. The high-toughness environment-friendly peelable adhesive is prepared from water-soluble resin, water, filler, an anti-foaming agent, a levelling agent, a toughening agent, a rheological agent and a pigment in certain proportions. The preparation method comprises the following steps: A, weighing various components in proportions; B, dissolving water-based resin in part water, adding the toughening agent, and stirring for 1.5 to 2.5 hours; C, adding the filler and the pigment into a mixed liquid, stirring uniformly, grinding 2 to 5 times by using a three-roller grinding machine, adding the rest water into the ground material, stirring 0.5 to 2 hours at 90 to 110 DEG C, adding the anti-foaming agent for performing anti-foaming treatment after the materials are stirred uniformly, and finally, adding the levelling agent and the rheological agent. The peelable adhesive provided by the invention has the characteristics of high film forming strength, high temperature resistance, low breaking elongation, environment-friendliness and the like; the use range is wide; the peelable adhesive is particularly suitable for protecting processes, such as cutting, carving, printing and film coating, in a touch screen process.
