Problems solved by technology

For example, if the above-mentioned PMMA and PC blended mobile phone case is printed with a pattern texture on the outer surface of the hand case, the pattern texture will often rub against human hands, desktops, etc. Sexual substances, resulting in exposed pattern texture is not durable, there will be different degrees of wear
If the pattern texture is printed on the inner surface of the mobile phone case, the internal pattern texture cannot be seen from the outside after the hand case is assembled because the transparency of the hand case is too low

Embodiment 1

[0033] The invention discloses a production process of a textured transparent glass fiber 3D mobile phone case, such as figure 1 shown, including the following steps

[0034] S1, preparing transparent resin glue; transparent resin glue is prepared by the following method: select 5-30 parts by weight of curing agent and catalyst composition, and add 100-200 parts by weight of resin, 0-50 parts by weight of Organic solvents are mixed and stirred to form.

[0035] S2, Coating: After the transparent resin glue is coated or injected on the continuous glass fiber cloth, it is refrigerated at a temperature below 0°C, so that the surface transparent resin glue can be quickly solidified to form a prepreg.

[0036] S3, Stacking: stack multiple layers of prepreg to form a certain thickness, and place a textured film on the surface. The textured film has two layers. The bottom layer is UV glue with texture, and the surface layer is PET as a transfer aid. glue, and the UV glue is next to...

Embodiment 2

[0040] Based on the textured 3D-shaped transparent glass fiber sheet produced in Example 1, the curing agent is a peroxide curing agent, the resin is an unsaturated polyester resin, and the organic solvent is styrene.

[0041] Stir 5 parts of peroxide curing agent and catalyst composition and 25 parts of styrene at 800-1000 rpm for 0.5-1.0 hours to obtain component A 1 , Stir 200 parts of unsaturated polyester resin and 25 parts of styrene at a speed of 800-1000 rpm for 0.5-1.0 hours to obtain component B 1 . Component A 1 and component B 1 Stir and mix in the reaction kettle to form transparent resin glue No. 1.

Embodiment 3

[0043] Different from the curing agent, resin and organic solvent in Example 2, the curing agent in Example 3 is a peroxide curing agent, the resin is polyurethane resin, and the organic solvent is acetone. Mix and stir 30 parts of peroxide curing agent and catalyst composition with 10 parts of acetone to obtain component A 2 , Mix and stir 100 parts of polyurethane resin and 10 parts of acetone to obtain component B 2 . Component A 2 and component B 2 Stir and mix in the reaction kettle to form transparent resin glue No. 2.

Abstract

The invention discloses a production process of a transparent 3D glass fiber board with textures. The production process comprises two production modes, wherein the first production mode comprises the following steps: S1, preparing a transparent resin glue solution; S2, coating to form a prepreg; S3, stacking; and S4, forming. During application, the transparent glass fiber board can be used for manufacturing a 3D mobile phone rear shell, the outer surface of the 3D mobile phone rear shell is a transparent glass fiber board, the inner surface of the 3D mobile phone rear shell is provided with UV glue ink, and the light transmittance of the transparent glass fiber board is 70-90%; and light penetrates through the transparent glass fiber board and is refracted and irradiated on the UV glue ink to form a snowflake effect with light and shade changes. The electronic product shell produced by the process provided by the invention has textures, and has the characteristics of drop resistance, flower texture drop prevention and durability at the same time.

Description

technical field [0001] The invention relates to the technology in the field of glass fiber plates, in particular to a production process and application of a textured transparent 3D glass fiber plate. Background technique [0002] Electronic product housings can be made from a wide variety of materials. The popular transparent mobile phone case on the market is the development trend of future products. Previously, glass shells appeared on the market, but due to insufficient strength and hardness, the impermeability rate in practical applications, and frequent breakage of shells, they have been eliminated by the industry. [0003] The more drop-resistant material is commonly PMMA material. However, since PMMA (acrylic) is a brittle material, the shell of an electronic product also has the defect of not being drop-resistant, so it is not suitable for application as a single material. Better, need to add PC material as reinforcement. Even so, its surface hardness is low. Aft...
