Problems solved by technology

These two traditional emulsion adhesives have poor water resistance, are easy to yellow, and have a heavy peeling force when rolled out, which is easy to cause white lines.
[0003] In order to improve these shortcomings, Taiwan Siwei Enterprise Co., Ltd. invented an emulsion adhesive for glazing film, which can be coated on polypropylene film, which can basically solve the problems of poor water resistance, easy yellowing and white lines. However, this adhesive The finished glazing film will still show a slight yellowing phenomenon after long-term use. Due to the superposition phenomenon, this phenomenon is especially prominent on unused glazing film in rolls
In the application, it affects the appearance of adhesive products, and even affects consumers' desire to buy.

Embodiment Construction

[0024] The examples given below specifically illustrate the present invention, but the present invention is not limited to these examples. The percentages in the following examples (unless otherwise specified) are all percentages by weight.

[0025] According to the formula in Table 1, component (A) is formed by emulsion polymerization. According to the formula in Table 2, component (B) is a mixture of water and strong reducing agent sodium hypophosphite at room temperature. According to the formula in Table 3, slowly add component (B) to component (A) and stir and mix uniformly at room temperature to obtain an emulsion type polyacrylate pressure-sensitive adhesive. The adhesive is now available and has the best performance.

[0026] Use the RK wire rod coater to coat the pressure-sensitive adhesive on the 19 μm BOPP film. The thickness of the adhesive layer is about 15 μm. The temperature is raised to 100°C. After drying, the thickness of the adhesive layer is about 7 μm. After ...

Abstract

The invention provides an emulsion type acrylic ester adhesive for an anti-yellowing polishing membrane and a preparation method thereof, and relates to the field of acrylic ester pressure sensitive tapes. The emulsion type acrylic ester pressure sensitive adhesive for the anti-yellowing polishing membrane provided by the invention is formed by mixing 97-99% of a component (A) and 1-3% of a component (B) in percentage by weight, wherein the component (A) is emulsion with polyacrylic ester as the main component, and the component (B) is strong reducing agent aqueous liquid. The emulsion type acrylic ester pressure sensitive adhesive prepared is coated on the surface of a carrier to form an adhesive coating, the thickness of which is 12-25 microns. The pressure sensitive tape with the thickness of 4-10 microns is prepared by drying at the reaction temperature of 80-120 DEG C. The polishing membrane prepared by the emulsion type adhesive is good in performances, simple in preparation process, free from pollution, low in cost and suitable for large-scale industrial production.

Description

Technical field [0001] The invention relates to an emulsion type polyacrylate pressure-sensitive adhesive for a glazing film, a glazing film prepared by using the adhesive, and a preparation method of the adhesive and the glazing film. Background technique [0002] In traditional technology, glazing film tape is used to protect printed materials on the printed surface such as thermal transfer printing, inkjet printing, offset printing, letterpress printing, and gravure printing to prevent moisture and sunlight from damaging the printed materials. The composition of this glazing film can be divided into two types on the answer. One is to include the substrate, adhesive and release paper to form a layered state. When in use, the release paper is peeled off and then attached to the pasted Things. The other is composed of three layers of base material, adhesive and release paper, which are directly attached to the substrate during use. These two traditional emulsion adhesives have ...
