Embodiment 1-5

[0043] A PS composite material with high strength, high heat resistance, antistatic properties and excellent barrier properties, its raw material formula is shown in Table 1, and its preparation method includes the following steps:

[0044] The above raw materials are uniformly mixed, and then fed from the main feeding port of the extruder. The raw materials are melted, extruded, and pelletized in the extruder to obtain PS with high strength, high heat resistance, antistatic, and excellent barrier properties. composite material; the pellets were injected into corresponding samples for testing, and the test results are shown in Table 2.

Embodiment 4

[0053] Compared with Comparative Example 3, Example 4 added copper acetate to reduce the resistance of the composite material.

Embodiment 1

[0054] Compared with Comparative Example 1, Example 1 added a toughening agent prepared from oil-extended SBS elastomer to improve the impact toughness of the composite material, and at the same time, the material could maintain better fluidity.

Abstract

The invention provides a HIPS composite material and a preparation method and application thereof, comprising the following components by mass percentage: HIPS resin: HIPS resin: 35-75 parts; PA resin: 15-40 parts; antistatic agent: 8-20 parts part; copper acetate: 0.1-0.5 part; toughening agent: 4-10 part; processing aid: 0.5-1.5 part. The HIPS composite material of the invention has the characteristics of high strength, high heat resistance, antistatic and excellent barrier properties.

Description

technical field [0001] The invention belongs to the field of modified plastics, and in particular relates to a HIPS composite material and a preparation method and application thereof. Background technique [0002] Styrene (PS) material is a common polymer, widely used in home appliances, electronic appliances, OA office equipment and other fields. Polystyrene material has the advantages of easy molding, good rigidity, and easy dyeing. However, the strength and heat resistance of PS materials are general, and the barrier properties are poor, which limits its application range. [0003] Due to the low polarity of conventional PS materials, the compatibility of materials modified by adding permanent antistatic agents with high polarity is not very good, especially when extruded products are easily delaminated. At the same time, the heat resistance of PS materials is general, and it cannot meet the requirements of some products with high temperature requirements, such as extr...
