Problems solved by technology

For example, CN110092960 A discloses that styrene-butadiene copolymer and transparent styrene are blended and modified to prepare a composition with high transparency, matte and certain toughness, but the toughening efficiency of this formula system is low, and it is The toughness improvement effect of GPPS is not obvious, and the application range of the material is limited
For another example, CN 105418830 A discloses a chemically synthesized modified SBS toughened GPPS material. Although the material obtained by this method has certain toughness, the preparation process is cumbersome, and chemically synthesized modification uses a large amount of organic solvents with certain toxicity. , and the improvement of the wear resistance of the material is not obvious, and the economic value and feasibility of large-scale production are low

Embodiment 1～8

[0038] Examples 1 to 8 provide a high-impact and wear-resistant transparent polystyrene composition, and its composition in parts by weight is shown in Table 1. The preparation method is as follows: Weigh each raw material component according to the formula, put all the components into the mixer, mix at a speed of 1000rpm for 5 minutes, take it out, and then plasticize the mixed raw material through a twin-screw extruder, extrude and pelletize , to obtain a high-impact wear-resistant transparent polystyrene composition. Wherein, the temperature of each section of the twin-screw extruder is 180-190° C., and the screw speed is 350-400 rpm.

[0039] Comparative Examples 1-5 provide a polystyrene composition, the formula of which is shown in Table 1 in parts by weight, and the preparation method refers to the preparation method of Examples 1-8. Wherein, the temperature control and the screw speed of the twin-screw extruder of Comparative Examples 1-5 are the same as that of Example...

Abstract

The invention discloses a high-impact wear-resistant transparent polystyrene composition as well as a preparation method and application thereof, and belongs to the technical field of engineering plastics. The transparent polystyrene composition is prepared from the following components in parts by weight: 58.5 to 78.5 parts of GPPS, 15 to 30 parts of a styrene-butadiene block copolymer, 5 to 10 parts of a styrene-methyl methacrylate copolymer and 0.5 to 1 part of a styrene-maleic anhydride copolymer, the melt flow rate of GPPS under the test conditions of 200 DEG C and 5kg is greater than or equal to 6g / 10min. The impact resistance and wear resistance of the GPPS are improved while the transparency of the GPPS is maintained, and the transparent material with high impact resistance and wear resistance is obtained.

Description

technical field [0001] The invention belongs to the technical field of engineering plastics, and in particular relates to a high-impact and wear-resistant transparent polystyrene composition and a preparation method and application thereof. Background technique [0002] In recent years, with the development of artificial intelligence and automation technology, the design of product appearance has become more and more diverse, among which the requirements for digital display and transparent display are also getting higher and higher, and the demand for transparent materials is increasing, especially It is the rapid development of the household appliance industry, electronics and health industries, which has led to a further increase in the demand for transparent resins. At present, commonly used transparent resins include polystyrene (GPPS), polymethyl methacrylate (PMMA), polycarbonate (PC), styrene-acrylonitrile (SAN) resin, transparent ABS (MABS), etc., but these All mate...
