Problems solved by technology

[0004] In order to solve the problem of low glass yield and lower glass transmittance caused by "smoke" treatment in the existing integrated black screen manufacturing process, the invention discloses an explosion-proof film for an integrated black screen and a preparation method thereof. Use of a black tie layer in the blast-proof film to obtain a black blast-proof film without the need to "smoke" the glass

preparation example Construction

[0035] The preparation method of explosion-proof film for integrated black screen is as follows:

[0036] Step 1. Weigh the resin, solvent, black color paste, and dispersant in sequence and add them to the liquid mixing tank, stir and disperse for 10-30 minutes, and let stand for defoaming to obtain a coating liquid with a solid content of 20-60%;

[0037] Step 2: Apply the prepared coating solution evenly on one side of the substrate layer 2, heat at 60-140°C for 1-5 minutes, and then fully cure by ultraviolet light or heating to obtain a black adhesive layer 3;

[0038] Step 3: Attach the release film layer 4 to the surface of the black adhesive layer 3 to ensure no air bubbles;

[0039] Step 4: Coating functional coating 1 on the other side of the substrate, and curing by ultraviolet light to obtain an explosion-proof film for an integrated black screen;

[0040] Wherein, the resin is one of acrylic resin, polyester resin, polyurethane resin and epoxy resin; the solvent is...

Embodiment 5

[0045] In Example 5, after step 2, the prepared coating solution was uniformly coated on one side of the substrate layer, and then left to stand for 5 minutes before heating and subsequent treatment. The treatment method of Comparative Example 1 was consistent with that of Example 5.

Embodiment 6

[0046] In Example 6, after step 2, the prepared coating liquid was uniformly coated on one side of the substrate layer, and then left to stand for 10 minutes before heating and subsequent treatment. The treatment method of Comparative Example 2 was consistent with that of Example 6.

Abstract

The invention belongs to the technical field of explosion-proof films, and specifically relates to an integral explosion-proof film for a black screen and a preparation method thereof. The integral explosion-proof film sequentially comprises a functional coating, a base material layer, a black adhesive layer, and a release film layer. By adopting the black adhesive layer, a black explosion-proof film is obtained; the glass does not need any fumigation process, which may influence the yield of glass products and light transmittance of glass, thus the glass processing cost and energy consumptionof electronic devices can be reduced; black color paste is added into an adhesive layer coating liquid to obtain the black adhesive layer, the operation is convenient, the whole process is barely influenced; the cost is low, the operation is easy; a silane coupling agent is added into the black adhesive layer coating liquid, the adhesion force between the adhesive layer and the base material layer / glass is improved; at the same time, the pigments are more evenly dispersed, and the light transmittance is maximally maintained after the addition of pigments.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof membranes, and in particular relates to an explosion-proof membrane for an integrated black screen and a preparation method thereof. Background technique [0002] After the screens of mobile phones, tablets, computers, TVs, etc. are turned on, the existence of the black border can be clearly seen. After the screen is turned off, the screen and the border are integrated, which is very beautiful. Only after it is extinguished can the color consistency be guaranteed. Nowadays, the preparation of black screen is usually to carry out "smoking" process on the glass of liquid crystal display panel, so that the color of the glass is consistent with the color of the frame. [0003] However, due to the characteristics of the glass material, the yield rate of the "smoke" treatment is low. At the same time, the light transmittance of the glass after the "smoke" treatment decreases, resulting in a dec...
