Embodiment Construction

[0022] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] This example proposes a method for preparing heat-resistant ABS resin, which is based on the process of synthesizing ABS resin by continuous bulk method.

[0024] The technological process and unit settings of ABS resin synthesis by continuous bulk method, such as figure 1 shown. Among them, the main units include: raw material unit, additive unit, sol unit, polymerization reaction unit, devolatilization unit and granulation unit; subsidiary units include circulating liquid unit, refrigeration unit, utility system and heat transfer oil system. The functions of each main unit are as follows:

[0025] 1. Raw material unit: Styrene, acrylonitrile and rubber are provided.

[0026] 2. Additive unit: provide corresp...

Abstract

The invention belongs to the technical field of polymer material preparation, and specifically relates to a heatproof ABS resin and a preparation method thereof. A mixer is arranged behind a secondaryde-volatilization device so as to fully mix a heatproof agent and ABS matrix polymer after secondary de-volatilization, and the heatproof performance of the ABS resin is enhanced. The modified ABS resin has the advantages of strong heatproof performance, balanced mechanical properties, and excellent processing property, and can replace polyester and alloy plastic.

Description

technical field [0001] The invention belongs to the technical field of polymer material preparation, and in particular relates to a heat-resistant ABS resin and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's automobile industry, the continuous improvement of the lightweight level of automobiles, and the increasing number of imported production lines, the demand for ABS resin in the automobile industry has increased rapidly, and it has become one of the most used plastics in automobiles. Many applications require ABS resin to have certain heat resistance, impact resistance and heat resistance and flame retardancy, such as automotive dashboards, integrated cover grilles and other components. The main production processes of ABS resin include emulsion grafting-bulk SAN blending method and continuous bulk method. Among them, the continuous bulk method is the best ABS resin production process, and its compr...
