Problems solved by technology

With the popularization and miniaturization of consumer electronic products and displays, the casing of portable products must have both the soft touch that people like and the display or display that does not affect the built-in pattern design. The light transmission of the decorative board Lightness has become an important characteristic. However, in the previous art, no discussion or improvement has been made on the light transmittance of the decorative board, and there is no hint or teaching of the previous art, how to improve or control the light transmittance of the decorative board, but It still maintains its necessary soft touch, which

Embodiment 1

[0079] see figure 1 Shown is a schematic structural view of a high-transmittance soft-touch material according to a preferred embodiment of the present invention. 11 is a transparent plastic substrate on which a soft-touch coating 12 is coated to form a structure 10 of a high-transmittance soft-touch material. The soft touch coating 12 is made by the following method:

[0080] Polyurethane resin A

100 copies

Isocyanate A

10 copies

curing catalyst

0.5 parts

Elastic particle A

80 copies

[0081] Stir and mix the above materials to obtain a resin formula, which is the material of the soft touch coating 12 . The material is coated on a polyethylene terephthalate (polyethylene terephthalate, PET) film or plate, and after drying at 80° C. for 15 minutes, a 60-micron soft-touch decorative plate 10 (such as figure 1 shown).

[0082] see figure 2 Shown is a schematic cross-sectional structure diagram of a high-transparency soft...

Embodiment 2

[0085] Stir and mix the above materials to obtain a resin formula, which is the material of the soft touch coating 12 . The material is coated on a polymethacrylic acid (PMMA) film or plate, and after drying at 80° C. for 5 minutes, a 100 micron thick soft-touch decorative plate 10 (such as figure 1 shown).

[0086] see figure 2 Shown is a schematic cross-sectional structure diagram of a high-transparency soft-touch decorative panel according to another preferred embodiment of the present invention. in such as figure 1 The surface of the soft-touch decorative board 10 shown is covered with polyurethane resin B as the transparent resin coating 21 on the surface of the soft-touch coating 12. This coating is about 1 to 2 microns thick to form a high-transparency soft-touch decoration Plate 20 with 40% light transmission.

Embodiment 3

[0088] After mixing the main agent (polyurethane resin L60H150 from Xinzhengfeng Company) and hardener (aliphatic isocyanate H79 from Xinzhengfeng Company) in proportion, after stirring evenly at room temperature, coat the translucent resin on a surface of 180 μm On a polycarbonate transparent substrate, the coating thickness is between 70 μm. The coating was dried at 80°C for 5 minutes to give samples A, B and C. Cover the surface of A with a layer of transparent resin about 1 to 2 microns thick to obtain A1; cover the surface of B with a layer of transparent resin about 2 to 4 microns thick to obtain B1; cover the surface of B with a layer of about 1 to 2 microns thick transparent resin 2 micron thick clear resin, yielding B2. The features of its surface are magnified 50 to 100 times under an optical microscope, and its photos are as follows Figure 6 Shown are the schematic diagrams of the observation photos A, B, C, A1, B1, B2 and E of the optical microscope of the high-...

Abstract

The invention relates to a high-light transmittance flexible touch material and a making method thereof. The high-light transmittance flexible touch material comprises a plastic substrate and a semi-transparent resin layer with a hemispherical surface, wherein the light transmittance of the plastic substrate is greater than 60%; the semi-transparent resin layer with the hemispherical surface is fully or partially arranged on the plastic substrate, the ratio of the exposed diameter dp of the protruded hemisphere to the average space Sm of protruded points is 0.1-0.8, and the integral light transmittance of the material is 10%-50%. The making method comprises the following steps of: selecting a high-light transmittance substrate and fully coating or partially printing one semi-transparent resin layer, wherein the surface of the semi-transparent resin layer is provided with hemispherical elastic granules; controlling the hemispherical elastic granules to ensure that the ratio of the exposed diameter dp of the protruded hemisphere to the average space Sm of the protruded points is 0.1-0.8 and the integral light transmittance of the material is 10%-50%. The method can improve the light transmittance of the flexible touch material, and back patterns of the flexible touch material are clear and visible, and the method can obtain the effect of simultaneously improving touch, decoration and information identification.

Description

technical field [0001] The present invention relates to a high light transmittance soft touch material and its manufacturing method, in particular to a material with high transparency and soft touch, and a manufacturing method including the material, which can be used in combination with other materials for various The shell of a product that people will touch with their hands, especially in communication and consumer electronics products, where both soft touch and light transmittance are required. The effect of high transparency makes the pattern information on the back of the material easily identifiable. Background technique [0002] It is a known technology to coat plastic materials with soft-touch materials for products that are often touched by human hands. In the early days, in order to provide a soft touch (for example, suede-like supple appearance) on the surface of the plastic molded product or metal molded product, a layer of suede-like coating material was direc...
