Abstract

The invention discloses an ABS material with lasting fragrance and a preparation method of the ABS material. The ABS material mainly comprises 70-90 parts of ABS resin, 10-20 parts of high rubber powder, 0.1-2 parts of an antioxidant, 0.1-2 parts of a light stabilizer and 1 part of lily fragrance master batch. According to the invention, through reasonable proportioning, the light stabilizer, theantioxidant and the types and dosages of the light stabilizer and the antioxidant suitable for improving the mechanical properties of the ABS material are preferably selected, a small amount of the fragrant master batch is added into the ABS material, so that the ABS material has a better taste improvement effect on the smell. The fragrant master batch is subjected to high-speed blending togetherwith a main material and an auxiliary agent and then subjected to extrusion granulation, and then post-treated and baked to obtain the durable fragrance ABS material with excellent comprehensive performance. The material also has the effect of improving the environment of the interior decoration of the household automobile, and has a relatively wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of engineering plastics, and in particular relates to a persistent fragrance ABS material and a preparation method thereof. Background technique [0002] Engineering plastics are widely used in automobile interior and exterior decoration, home appliances, notebook computers and other products because of their wide source of raw materials, low price, excellent heat resistance and easy molding processing, and have become the fastest growing industry. One of the plastic varieties. In recent years, with the continuous improvement of people's living standards and the continuous development of science and technology, people have higher and higher requirements for the health and environmental protection of ABS plastics and their products, especially for some ABS plastics that often come into contact with the human body. Products, such as some household appliances, daily necessities and automotive interior parts, e...
