Embodiment 1

[0050] Prepare TPO artificial leather according to the following method:

[0051] In the first step, add the non-polar resin, main toner and auxiliary toner into the twin-screw extruder according to the translucent masterbatch formula in Table 1, extrude and cut to obtain the masterbatch;

[0052] In the second step, according to the TPO skin layer formula in table 1, polyolefin elastomer, polyolefin resin, rubber and the color masterbatch made by the first step are added in the twin-screw extruder in the form of composition, Heat and melt each component at 200°C and mix them evenly. Then the obtained mixture is extruded to prepare a TPO skin layer with a thickness of 0.5mm;

[0053] The third step is to evenly coat a layer of water-based polyurethane system paint with a thickness of about 0.2 μm on one side of the TPO skin layer by gravure printing to improve the feel, wear resistance and scratch resistance of the surface layer;

[0054] In the fourth step, the obtained TPO...

Embodiment 2

[0064] According to the formula of light-transmitting color masterbatch in Table 3 and the formula of TPO epidermis, adopt the same method as Example 1 to prepare TPO artificial leather, and adopt the same light transmittance detection method as in Example 1 to detect the light transmittance of TPO artificial leather , and the results of light transmittance are also shown in Table 3.

Abstract

The invention relates to a TPO composition having a light-transmitting property, the TPO composition comprises a polyolefin elastomer POE, a polyolefin resin, a rubber, and a light-transmitting colormaster batch, and the light-transmitting color master batch comprises 50-70 parts by weight of a non-polar resin and 30-50 parts by weight of a toner based on 100 parts by weight of the total weight of the light-transmitting color master batch. The invention also relates to TPO artificial leather which comprises a TPO surface layer formed by the TPO composition. The TPO artificial leather according to the present invention can be applied to automotive interiors, and can achieve good light transmittance while satisfying desired color coverage.

Description

technical field [0001] The invention relates to a thermoplastic polyolefin elastomer (also called TPO) composition with light-transmitting properties, and a TPO artificial leather made from the TPO composition. Background technique [0002] TPO artificial leather is widely used in automotive interiors, and its advantages are that it has good thermodynamic properties, does not contain halogens, has low emission, and has no plasticizers, etc. For example CN106393890A discloses a kind of ultra-soft environment-friendly TPO automobile interior material, wherein with soft TPO epidermis, soft sponge formula, the soft feel of interior material has been promoted, and surface coating is carried out with soft water-based polyurethane paint, The three-layer structure improves the soft performance of the material and reduces the density of the product. [0003] With the development of society, people not only pay attention to performance when buying cars, but also put forward higher re...
