Problems solved by technology

[0003] And this method of protecting by pasting a layer of yellow tape or electrostatic tape on the surface of the LCD screen has many shortcomings: 1) when pasting, it needs to be cut according to the size of the liquid crystal screen; Poor, resulting in some parts not being protected; 3) There will be residual glue pollution on the surface of the LCD screen during peeling, which requires manual cleaning, which reduces production efficiency

Embodiment 1

[0034] The raw material composition and content of heat-curing peelable blue glue are as follows: 40 parts of paste resin, 10 parts of filler, 20 parts of dioctyl phthalate, [KH-570]γ-(methacryloxy)propyl trimethoxy 0.2 part of base silane, 0.4 part of polymethylphenylsiloxane, 0.2 part of fumed silica, 0.5 part of Airex900 and 0.2 part of phthalocyanine blue PB15:3. The above-mentioned raw materials are dispersed, stirred and mixed to prepare a heat-curable peelable blue glue for temporary protection of liquid crystal screen processing and manufacturing.

[0035] In this embodiment, the paste resin is a mixture of polyvinyl chloride paste resin P450 and binary vinyl acetate paste resin, and the mass ratio is 1:1.5.

Embodiment 2

[0037] The raw material composition and content of heat-curable peelable blue glue are as follows: paste resin 50 parts, filler 15 parts, dioctyl phthalate 28 parts, [KH-570]γ-(methacryloxy)propyl trimethoxy 0.5 part of base silane, 0.4 part of polymethylphenylsiloxane, 0.5 part of fumed silica, 0.5 part of Airex900, and 0.4 part of phthalocyanine blue PB15:3. The above-mentioned raw materials are dispersed, stirred and mixed to prepare a heat-curable peelable blue glue for temporary protection of liquid crystal screen processing and manufacturing.

[0038] In this embodiment, the paste resin is a mixture of polyvinyl chloride paste resin P450 and binary vinyl acetate paste resin, and the mass ratio is 1:1.5.

Embodiment 3

[0040] The raw material composition and content of the heat-curable peelable blue glue are as follows: 60 parts of paste resin, 20 parts of filler, 28 parts of dioctyl phthalate, [KH-570]γ-(methacryloxy)propyl trimethoxy 1 part of base silane, 0.4 part of polymethylphenylsiloxane, 0.5 part of fumed silica, 0.5 part of Airex900, and 0.4 part of phthalocyanine blue PB15:3. The above-mentioned raw materials are dispersed, stirred and mixed to prepare a heat-curable peelable blue glue for temporary protection of liquid crystal screen processing and manufacturing.

[0041] In this embodiment, the paste resin is a mixture of polyvinyl chloride paste resin P450 and binary vinyl acetate paste resin, and the mass ratio is 1:1.5.

Abstract

Thermosetting peelable blue gum comprises, by weight, 30-60 parts of paste resin, 10-30 parts of a filling material, 10-30 parts of a plasticizer, 0.1-1 part of silane coupling agent, 0.1-1 part of a defoaming agent, 0.1-1 part of a thixotropic agent, 0.03-1 part of a leveling agent, and 0.1-1 part of a pigment. The thermosetting peelable blue gum has good toughness and flexibility, is highly adhesive to a liquid crystal screen, and is tolerant to high-pressure water flushing with zero delamination; a film of the thermosetting peelable blue gum can tolerate acidic and alkaline solutions and can protect a liquid crystal screen from being corroded by an acid during production.

Description

Technical field [0001] The invention relates to the technical field of polymer materials, in particular to a heat-curable peelable blue glue used for the processing and manufacturing of liquid crystal screens. Background technique [0002] In recent years, the domestic electronics industry has developed rapidly, and the demand for LCD screen processing and manufacturing has also increased. However, LCD screens will encounter many problems during the production and manufacturing process, such as scratches, pollution, and acid corrosion of the edges of the LCD screen. , Eventually leading to the scrap of the LCD screen, resulting in a high rate of defective production. Therefore, temporary protection has become a necessary process in the processing and manufacturing of LCD screens. The current temporary protection method is generally to stick a layer of yellow tape or electrostatic tape on the surface of the LCD screen for protection. [0003] However, this method of protecting the ...
