Problems solved by technology

Because the price of the backing paper is relatively high compared to the colloid and the film, the cost is high, and the backing paper that is removed after the construction is generally discarded directly, resulting in the backing paper containing silicone oil, which is easy to pollute the environment.

Abstract

The invention discloses acrylic acid pressure-sensitive adhesive and a method for preparing the same. The acrylic acid pressure-sensitive adhesive comprises, by weight, 45-90 parts of soft monomers, 1-40 parts of hard monomers, 0.1-5% of functional monomers, 0.1-2 parts of initiators, 2-5 parts of tackifiers, 1-5 parts of organosilicon polymers, 0.1-2 parts of curing agents and 40-60 parts of solvents. The acrylic acid pressure-sensitive adhesive and the method have the advantages that body paper for the acrylic acid pressure-sensitive adhesive can be omitted, accordingly, the acrylic acid pressure-sensitive adhesive is convenient to use and is environmentally friendly, and the cost can be saved.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, in particular to an acrylic pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Existing pressure-sensitive adhesives need to cover the backing paper when they are used, especially the cold lamination film on the advertising material or the car film on the vehicle body, and the backing paper should be removed during construction. Because the price of the backing paper is relatively high compared to the colloid and the film, the cost is high, and the backing paper removed after the construction is generally discarded directly, resulting in the backing paper containing silicone oil and easily polluting the environment. Contents of the invention [0003] The main purpose of the present invention is to provide an acrylic pressure-sensitive adhesive, which is more convenient to use, environment-friendly and cost-saving. [0004] In order ...
