Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automotive interior, especially to a kind of anti-fouling weather-resistant organic silicon light-transmitting leather for automotive interior. BACKGROUND

[0002] With the development of automotive intelligent cabin, more and more soft intelligent surfaces are applied in interior, such as auxiliary instrument panel, door panel, etc., which improves the atmosphere and human-computer interaction interest of automotive interior, providing more space for the development of intelligent materials.

[0003] The light-transmitting leather applied to soft intelligent surface needs to balance the light transmission with backlight and the shielding property without backlight, and also needs to realize the performance requirements such as wear resistance, aging resistance and dirt resistance of multiple colors.

[0004] The commonly used light-transmitting leather materials on the market at present mainly include polyvinyl chloride (PVC), polyurethane (PU) and thermoplastic polyolefin (TPO).

[0005] The hierarchical structure of PVC light-transmitting leather is usually: water-based surface treatment layer + light-transmitting PVC color layer + pattern layer + PVC substrate layer + base cloth.

[0006] The hierarchical structure of PU light-transmitting leather is usually: water-based surface treatment layer + light-transmitting PU color layer + pattern layer + base cloth.

[0007] The hierarchical structure of TPO light-transmitting leather is usually: surface treatment layer + light-transmitting TPO color layer + pattern layer.

[0008] The process of the above-mentioned pattern layer includes but is not limited to silk printing, roller printing and laser engraving, and the base cloth can be selected according to actual use.

[0009] However, the main disadvantages of the existing scheme are:

[0010] PVC, PU and TPO materials have limitations in color adjustment. When they are adjusted to light-colored leather (according to the definition of CIELAB color space, when L value ≥ 50), the dirt resistance and aging resistance of light-transmitting leather become poor (the conventional requirement for automotive interior is that the color change is ≥ 4 levels, and the light-transmitting leather of the existing scheme is < 4 levels).

[0011] The reasons for the above-mentioned disadvantages are:

[0012] 1. When PVC, PU and TPO materials are adjusted to light-transmitting leather, the proportion of materials such as pigments is greatly reduced to reduce the color density, so that the shielding property of leather to external dirt and yellowing defect after aging decreases, and the color change is obvious.

[0013] 2. Based on the characteristics of PVC, PU and TPO materials, color change is prone to occur under the influence of external substances, ultraviolet rays and temperature. Utility model content
