Problems solved by technology

However, the smaller the particle size of the metal powder, the easier it is to have a curve at the junction of the weld line, so the improvement of the weld line is not obvious, and the impact and weather resistance are not explained.
[0005] However, there is no report on a component that is suitable for automotive interior components, has metallic luster, ultra-high toughness and excellent weather resistance and its preparation method

Embodiment 4-10

[0087] The preparation method of the metallic luster ABS material of embodiment 4-10:

[0088] (a) prepare materials according to the described components and percentage by weight;

[0089] (b) Place each component of the prepared material in a high-speed mixer, and mix for 5 to 20 minutes to obtain a mixed material;

[0090] (c) adding the mixture into a twin-screw extruder, extruding and preparing a metallic luster ABS sheet, wherein the barrel speed of the twin-screw extruder is 15-35 rpm, and the barrel temperature is 200-240°C.

[0091] (d) Making the obtained metallic luster ABS sheet into a component after blister molding. Blister forming temperature is 220-270°C, mold temperature is 60-100°C.

[0092] Evaluation of the implementation effect:

[0093] With the metallic luster ABS material sample that above-mentioned comparative example 1-6 and embodiment 1-10 obtain, product performance test method is as follows:

[0094] Melt index: according to ISO 1133, tested un...

Embodiment 14

[0127] According to Table 7, put the plastic parts of metallic luster ABS into the mold, and then insert them with PC alloy materials to make metallic luster composite material parts through insert injection molding. The bottom layer is metallic luster ABS material, and the surface layer is PC alloy material.

[0129]

[0130] Evaluation of the implementation effect:

[0131] Metal effect and weld line state: evaluated visually; the metal effect is divided into 10 grades, the higher the grade, the better the metal effect; the weld line state is divided into 10 grades, the higher the grade, the less obvious the weld line.

[0132] Falling Ball Impact: According to PV3905.

[0133] From Table 7, it can be seen that the combined material parts of Embodiment 9 and Embodiment 11 have the best metal effect, weld line and flow mark state, and ball impact performance. If the addition amount of SX-006 is too high, it will affect the transparency, s...

Abstract

The invention relates to the field of polymer materials, in particular to a combinatorial material with metal luster, ultrahigh toughness and excellent weather resistance and a preparation method of the combinatorial material. The combinatorial material is prepared from two materials by insert molding, wherein the bottom layer is an ABS material with metal luster, and the surface layer is a transparent PC alloy material with excellent weather resistance. The combinatorial material overcomes the defects of flow marks, weld lines and the like caused by metal powder orientation in an injection molding process of the material with metal luster, solves the problem of sharply decreased impact property due to addition of the metal powder, and has good weather resistance, so that the surface layerneeds no painting treatment, and manufacture cost can be reduced; the material can be applied to design of various complicated parts, thereby being possibly applied as automotive interior trimming.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a composite material with metallic luster, ultra-high toughness and excellent weather resistance, which is suitable for automotive interior parts and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is a linear polycarbonate, an amorphous engineering plastic with good toughness, transparency and heat resistance. ABS has good fluidity and impact performance. Therefore, the blending of PC and ABS can combine the excellent properties of both PC and ABS, which can not only improve the heat resistance and tensile strength of ABS, but also reduce the melt viscosity of PC, improve processing performance, and reduce the risk of stress cracking. sensitivity and can reduce costs. So PC / ABS is often used as a car interior material. At present, in the design of automotive interior parts, in order to achieve the effect of metallic texture, processes such as sp...
