Embodiment Construction

[0019] The formula used in this embodiment is:

[0020] Isooctyl acrylate 35%

[0021] Butyl acrylate 10%

[0022] Vinyl acetate 15%

[0023] Acrylic 4%

[0024] Azobisisobutyronitrile 5‰

[0025] Ethyl acetate 16%

[0026] Ethanol 18%

[0027] Curing agent 5‰

[0028] Nano-level AL 5‰

[0029] Surfactant 5‰.

[0030] The preparation process steps and conditions of this embodiment are:

[0031] According to the above raw material formula, mix isooctyl acrylate, butyl acrylate, vinyl acetate, acrylic acid, azobisisobutyronitrile, ethyl acetate and ethanol uniformly, and then add them to the reactor. The addition amount is 1 / 5 of the reactor. Start heating, after reacting at 70-85°C for 1-2 hours, add the remaining reactants dropwise and complete the dropwise addition within 2-5 hours. After the dropwise addition is completed, keep it for 2-5 hours and then cool to below 50°C , Add the curing agent, and then the material can be discharged; the discharged semi-finished glue is put in...

Abstract

The present invention provides an acrylic unctuous pressure-sensitive adhesive, which is characterized by silver gray, initial adhesion equal to or more than 8, 180-degree peeling force equal to or more than 10 / inch and sustained adhesion equal to or more than 24h. The material formula of the acrylic unctuous pressure-sensitive adhesive contains 2-ethylhexyl acrylate, butyl acrylate, winyl acetic ester, acrylic acid, azodiisobutyronitrile, ethyl acetate, ethanol, curing agent, nano-AL powder and surfactant. The present invention also provides a method for preparing the acrylic unctuous pressure-sensitive adhesive. The acrylic unctuous pressure-sensitive adhesive provided by the present invention not only has good balance of initial adhesion, peeling force and sustained adhesion but also has a silver-gray metal color and good color covering degree.

Description

Technical field [0001] The invention belongs to the technical field of pressure-sensitive glue, and specifically relates to a silver-gray acrylic oil-based pressure-sensitive glue and a preparation method thereof. Background technique [0002] Colorless acrylic pressure-sensitive adhesives are used the most. In recent years, with the needs of various applications, the demand for colored acrylic oil-based pressure-sensitive adhesives has gradually increased. However, there has been no report on acrylic pressure-sensitive adhesives with metallic luster so far. Summary of the invention [0003] The purpose of the present invention is to provide a silver-gray acrylic oil-based pressure-sensitive adhesive and a preparation method thereof in view of the deficiencies of the existing acrylic pressure-sensitive adhesives. [0004] The technical scheme of the present invention is: [0005] An acrylic oil-based pressure-sensitive adhesive, characterized in that the color is silver-gray, th...
