Abstract

The invention discloses a peelable protective blue gel and a preparation method thereof. The peelable protective blue gel comprises a component A and a component B, wherein the component A is mainly prepared from the following raw materials in parts by weight: 25 to 40 parts of polyester resin, 5 to 10 parts of vinyl chloride-vinyl acetate copolymer, 30 to 40 parts of amino resin, 13 to 20 parts of a plasticizer, 3 to 9 parts of silicon dioxide, 3 to 5 parts of a viscosity reducer, 1 to 3 parts of A blue pigment, 0.5 to 1.5 parts of a defoaming agent, 2 to 4 parts of a membrane-forming agent and 2 to 3 parts of isophorone; and the component B is a curing agent and accounts for 1-2 parts by weight. The invention also provides a preparation method of the peelable protective blue gel. The method comprises the following steps: weighing the component A and the component B, adding the component A into homogenizing equipment, adding into a three-roller machine, mixing the component A and thecomponent B, and stirring to obtain the peelable protective blue gel. After the peelable protective blue gel is used on a glass cover plate, cleaning of a flat plate cleaning machine can be dealt with, the phenomena of peelable glue edge curling and overall falling off during cleaning are avoided, damage caused by copying and back washing of the glass cover plate is reduced, and therefore the product yield is increased.

Description

technical field [0001] The invention relates to a peelable protective blue glue, which belongs to the field of glass panel preparation. Background technique [0002] Spraying AG anti-glare is a kind of deep processing technology for glass cover plate. The processing technology is convenient and fast, and the production efficiency is high. It can conveniently process high-quality products with different gloss and haze. During the spraying process, there are some areas on the surface of the glass that do not need to be sprayed with AG, such as IR holes, LOGO, transparent holes, etc., and this part needs to be covered and protected. There are currently three methods of covering protection: UV protective ink, PET film, and peelable glue. If you use UV protective ink, you need to use a special cleaning agent to clean it after spraying AG, but it will damage the gloss of the surface of the sprayed AG glass cover; if you use PET film, you need to customize the corresponding graphi...
