Problems solved by technology

[0003] However, through practice, it is found that there are more or less flow marks on the appearance of spray-free thermoplastic engineering plastic injection molded parts, which greatly reduces the appearance quality of the product
In order to solve this problem, engineers and technicians have also done a lot of research work in this area, but the problem has not been effectively solved

Embodiment 1

[0042] Mix 82 parts of Chimei's PA-709, 2 parts of light stabilizer, 2 parts of heat stabilizer, 10 parts of chemical treatment agent, 2 parts of processing aid, and 2 parts of aluminum silver powder through high-speed stirring, and send the above mixture into the twin-screw In the extruder, it is fully melted and compounded under the conveying and shearing action of the screw, and then extruded through the head die, drawn, cooled and pelletized.

[0043] The temperature of the first zone of the twin-screw extruder is controlled at 200°C, the temperature of the screws from the second zone to the head of each section is controlled between 220 and 260°C, and the screw speed is 350r / min.

[0044] Injection molded into a test sample part, the degree of flow marks on the surface of the part and the brightness of the metal effect on the surface of the part were tested. The results are shown in Table 3.

Embodiment 2

[0050] Mix 90 parts of Chimei PA-709, 1 part of light stabilizer, 1 part of heat stabilizer, 6 parts of chemical treatment agent, 1 part of processing aid, and 1 part of aluminum silver powder through high-speed stirring, and send the above mixture into the twin-screw In the extruder, it is fully melted and compounded under the conveying and shearing action of the screw, and then extruded through the head die, drawn, cooled and pelletized.

[0051] The temperature of the first zone of the twin-screw extruder is controlled at 200°C, the temperature of the screws from the second zone to the head of each section is controlled between 220 and 260°C, and the screw speed is 350r / min.

[0052] Injection molded into a test sample part, the degree of flow marks on the surface of the part and the brightness of the metal effect on the surface of the part were tested. The results are shown in Table 3.

Embodiment 3

[0058] Mix 97.25 parts of Chimei's PA-709, 0.5 part of light stabilizer, 0.1 part of heat stabilizer, 2 parts of chemical treatment agent, 0.1 part of processing aid, and 0.05 part of aluminum silver powder through high-speed stirring, and send the above mixture into the twin-screw In the extruder, it is fully melted and compounded under the conveying and shearing action of the screw, and then extruded through the head die, drawn, cooled and pelletized.

[0059] The temperature of the first zone of the twin-screw extruder is controlled at 200°C, the temperature of the screws from the second zone to the head of each section is controlled between 220 and 260°C, and the screw speed is 350r / min.

[0060] Injection molded into a test sample part, the degree of flow marks on the surface of the part and the brightness of the metal effect on the surface of the part were tested. The results are shown in Table 3.

Abstract

The invention discloses an acrylonitrile-butadiene-styrene composition for solving spray-free flow marks and a preparation method thereof. The composition includes acrylonitrile-butadiene-styrene resin: 82-97.25 parts, light stabilizer : 0.5-2 parts, heat stabilizer: 0.1-2 parts, chemical treatment agent: 2-10 parts, processing aid: 0.1-2 parts, metal powder pigment: 0.05-2 parts. This invention creatively provides a solution of a new idea and technical route in terms of materials. The spray-free metal effect acrylonitrile-butadiene-styrene composition of the invention is used for parts produced by injection molding, which completely eliminates the The flow mark defects on the appearance of the parts greatly improve the appearance quality of the product, reduce the rate of defective injection molding products, and bring considerable benefits to production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an acrylonitrile-butadiene-styrene composition and a preparation method thereof for solving flow marks on the surface of spray-free material parts. Background technique [0002] Spray-free thermoplastic engineering plastics are designed to give the material a metallic appearance in the material preparation stage, thereby eliminating the need to re-spray the appearance of the part in the later stage, which can not only reduce production costs, shorten the development cycle, but also reduce The purpose of environmental protection is to produce toxic and harmful gases and other polluting substances to the environment during the spraying process. [0003] However, through practice, it is found that there are more or less flow marks on the appearance of spray-free thermoplastic engineering plastic injection molded parts, which greatly reduces the appearance quali...
