Embodiment 1

[0033] The present invention proposes a kind of toughening GPPS material preparation method, and this method is that GPPS, styrene-butadiene copolymer and color masterbatch are evenly stirred and mixed, and GPPS is mixed with styrene-butadiene copolymer and color masterbatch in particle state The masterbatch is mixed, the GPPS particles are spherical and / or cylindrical in structure, and the particle size of the GPPS particles is 1-5mm.

[0034] Wherein the parts by weight of each component are:

[0035] GPPS 50—90 copies

[0036] Styrene-butadiene copolymer 8—50 parts

[0037] Color masterbatch 1-10 parts.

[0038] As a further embodiment, the color masterbatch includes oily toughening agent, styrene-butadiene copolymer carrier resin and dyeing agent. The oily toughening agent is transparent toughening oil, and the mass fraction of the oily toughening agent in the color masterbatch is 1%-35%. The styrene-butadiene copolymer carrier resin is compatible with the styrene-buta...

Embodiment 2

[0047] The specific technological process of the toughened GPPS material preparation method proposed in the present embodiment is:

[0048]In the first step, according to the properties of the toughened GPPS material to be prepared, an oily toughener, a styrene-butadiene copolymer carrier resin and a coloring agent are selected according to the mass fraction to prepare color masterbatches. In this step of this embodiment, the mass fraction of the oily toughening agent in the masterbatch is 1%, the mass fraction of the styrene-butadiene copolymer carrier resin in the masterbatch is 95%, and the dyeing agent accounts for 95% of the masterbatch. The mass fraction of granules is 4%, and the dyeing agent of different colors can be selected according to the purpose of the prepared GPPS material, and the organic dyeing agent is selected in this embodiment.

[0049] In the second step, GPPS, styrene-butadiene copolymer and color masterbatch are selected according to the ratio of parts...

Embodiment 3

[0054] The specific technological process of the toughened GPPS material preparation method proposed in the present embodiment is:

[0055] In the first step, according to the properties of the toughened GPPS material to be prepared, an oily toughener, a styrene-butadiene copolymer carrier resin and a coloring agent are selected according to the mass fraction to prepare color masterbatches. In this step of this embodiment, the mass fraction of the oily toughening agent in the color masterbatch is 20%, the mass fraction of the styrene-butadiene copolymer carrier resin in the color masterbatch is 70%, and the dyeing agent accounts for the color masterbatch The mass fraction of granules is 10%, and different color dyes can be selected according to the purpose of the prepared GPPS material. In this embodiment, organic dyes are selected.

[0056] In the second step, GPPS, styrene-butadiene copolymer and color masterbatch are selected according to the ratio of parts by weight. In t...

Abstract

The invention relates to the technical field of plastic preparation, and discloses a preparation method of a toughened GPPS material, a toughened GPPS material and plastic parts, and uniformly stirs and mixes GPPS, styrene-butadiene copolymer and color masterbatch; each component The parts by weight are: 50-90 parts of GPPS; 10-50 parts of styrene-butadiene copolymer; 1-10 parts of color masterbatch. The present invention adopts GPPS, styrene-butadiene copolymer and color masterbatch three kinds of raw materials to mix directly and evenly to make GPPS material, and the production preparation process is simple, the operation steps are few, the production preparation efficiency is high, and there is no need to use during the production preparation process. Dust pollution will occur; the GPPS material prepared by the preparation method of the present invention has high toughness, good impact resistance and good gloss.

Description

technical field [0001] The invention relates to the technical field of plastic preparation, and in particular to a method for preparing toughened GPPS material, toughened GPPS material and plastic parts. Background technique [0002] GPPS is general-purpose polystyrene. It is a commonly used plastic, which is polymerized from styrene monomer. It has many advantages such as good transparency, low material cost, and simple molding process. GPPS materials can be polymerized by a variety of synthetic methods. At present, bulk polymerization and suspension polymerization are mainly used in industry. Because GPPS material has the above advantages, it is widely used in various plastic products. However, due to the performance of GPPS itself, plastic parts made of GPPS have low impact strength and are prone to brittle fracture. [0003] Therefore, improving the toughness of GPPS materials so that they can replace high-gloss tough plastic parts such as ABS and PC, reducing the cost ...
