preparation example Construction

[0043] The present invention also relates to the preparation method of spray-free material, its flow chart is as follows figure 1 As shown, including the above-mentioned components, namely PC resin, ABS resin, PA6 resin, compatibilizer, antioxidant and melt index improver, adding aluminum silver powder according to the situation, mixing evenly, granulating, and drying to obtain The spray-free material of the present invention.

[0044] In one embodiment of the present invention, the mixing is performed by a high-speed mixer, and the mixing time is 1-2 minutes. High-speed mixers generally refer to high-speed mixers in the plastics industry, which are suitable for mixing powders, granules, additives, toners, masterbatches, plastics and other materials. The barrel adopts an arc-shaped structure, and the special blade structure is mainly used to make the material form a vortex-like high-speed stirring, and can be modified by heating.

[0045] In one embodiment of the present inv...

experiment example

[0047] Pour the resin and other auxiliary materials into a high-speed mixer and mix for 1-2 minutes, then granulate through a twin-screw extruder, and the extrusion processing temperature is 210-235°C. See Table 1 for the proportions of each component of Examples 1-5 and Comparative Examples 1-3.

Abstract

The invention provides a spraying-free material, which comprises the following components by weight: 60-70 parts of PC resin, 20-40 parts of ABS resin, 1-5 parts of PA6 resin, 1-4 parts of a compatilizer, 0.1-1 part of an antioxidant and 0.4-0.6 part of a melt index improver. The invention also provides a preparation method of the material, and the method includes: compounding the PC resin, ABS resin, PA6 resin and other auxiliary materials, and carrying out extrusion granulation. The material has the advantages of high glossiness, good metal texture, environmental protection, no toxicity andlow processing cost. Meanwhile, compared with spraying-free materials in the prior art, the material has good tensile strength and impact strength.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a spray-free material and a preparation method thereof. Background technique [0002] At present, spraying, as a very mature technology, is used in all aspects of national life. In order to meet the pursuit of aesthetics and personalization in life, products are often processed by spraying to achieve rich and diverse product colors. However, with the development of technology and the society's requirements for environmental protection, some defects of spraying are increasingly magnified. For example, the sprayed paint film is easy to fall off, and the paint is easy to produce a variety of harmful gases, which are harmful to the human body and the environment. [0003] Spray-free materials can be directly injection molded into various plastic parts, and can show the desired appearance effect without post-processing. At the same time, no or very little VOC gas ...
