Problems solved by technology

1. The design and layout of the pattern layer is far away from the skin layer. The backlight passes through the pattern layer, and the visible light is diffused, resulting in low resolution of the pattern display; The shadow of the layer cloth pattern appears on the surface of the decorative layer; 3. The pattern design adopts laser engraving, laser engraving, printing and other schemes, the processing efficiency is low, and the industrialization cost is high

Embodiment 1

[0055] This embodiment discloses a method for preparing a soft-touch light-emitting decoration material, which includes the following preparation steps:

[0056] (1) Preparation of light-transmitting epidermal layer 1:

[0057] Its raw materials include: 100 parts of polyvinyl chloride resin, 70 parts of diisodecyl phthalate, 3 parts of calcium zinc stabilizer, 3 parts of antimony trioxide, 0.7 parts of triphenyl phosphite antioxidant, 0.8 parts of ultraviolet absorber 2 parts, 2 parts of organotin plasticizing accelerator, 4 parts of epoxy soybean oil, 2 parts of organic pigment.

[0058] Put the above raw materials into a high-speed mixer in turn to stir and disperse fully, then coat the above slurry on a coating machine, and dry it in a drying pipeline at 180°C for 45 seconds. Light-transmitting epidermis layer-controls the thickness of 0.2-0.3 mm by controlling the gap of the coating knife.

[0059] (2) Preparation of light-transmitting epidermis and composite pattern la...

Embodiment 2

[0070] This embodiment discloses a method for preparing a soft-touch light-emitting decoration material, which includes the following preparation steps:

[0071] (1) Preparation of light-transmitting epidermal layer 1:

[0072] The raw materials include: BASF polyurethane elastomer resin TPU C60A 80 parts, Covestro polyurethane elastomer resin TPU 9370A 20 parts, Ciba antioxidant Irganox 1010 0.3 parts, Ciba light stabilizer Tinuvin 328 0.4 parts, Covestro anti-hydrolysis agent 1 part of Stabaxol P200, 2 parts of TPU organic masterbatch.

[0073] Put the above-mentioned raw materials in a high-speed mixer in order to stir and fully disperse, then put the above-mentioned blend into the extruder for plasticizing and extruding, pass through the extruder at a temperature of 180-190°C, and pass the light-transmitting skin layer through the control of the rollers of the calender The gap control thickness is 0.25mm.

Embodiment 3

[0085] This embodiment discloses a method for preparing a soft-touch light-emitting decoration material, which includes the following preparation steps:

[0086] (1) Preparation of light-transmitting epidermal layer 1:

[0087] Its raw materials include: 100 parts of polyvinyl chloride resin, 70 parts of diisodecyl phthalate, 3 parts of calcium zinc stabilizer, 3 parts of antimony trioxide, 0.7 parts of triphenyl phosphite antioxidant, 0.8 parts of ultraviolet absorber 2 parts, 2 parts of organotin plasticizing accelerator, 4 parts of epoxy soybean oil, 2 parts of organic pigment.

[0088] Put the above raw materials in a high-speed mixer in turn to stir and disperse fully, then apply and scrape on the release paper of the coating table, and plasticize through an oven at a temperature of 150-180°C to obtain a light-transmitting skin layer 1. Light-transmitting epidermis layer-controls the thickness of 0.2-0.3 mm by controlling the gap of the coating knife.

Abstract

The invention discloses a soft-touch luminous ornament material as well as a preparation method and application thereof, and belongs to the technical field of automotive interior materials. The soft-touch luminous ornament material comprises a light-transmitting surface layer I, a pattern layer, a light-transmitting surface layer II, a light-transmitting soft touch layer, a light-transmitting skeleton layer and a backlight source sequentially distributed from top to bottom, wherein the pattern layer is obtained by carrying out high-definition digital printing on quick-dry ink, and the color and the using effect of the pattern layer are changed along with the change of the backlight source. The soft-touch luminous ornament material designed by the invention not only can realize high pattern display resolution, but also is relatively low in manufacturing and industrialization cost, and can meet the requirements of refined and personalized pattern modeling design.

Description

technical field [0001] The invention relates to a material with soft touch, which belongs to the technical field of automotive interior materials, and in particular to a soft touch luminous decoration material and its preparation method and application. Background technique [0002] At present, in order to meet consumers' intelligent, high-end, and individualized demands for automotive interior decoration parts, automobile OEMs are focusing on improving the design sense of cockpit interiors to improve user experience and vehicle quality. Traditional decoration techniques such as leather-covered decoration, in-mold decoration, and solid wood decoration have the problems of monotonous design and aesthetic fatigue. The standard ambient light for mid-to-high-end cars can heighten the atmosphere inside the car and create a mood for the whole car, but it cannot achieve complex patterned lighting effects, and the decorative effect is single, which cannot meet the growing high-end a...
