[0041] The preparation method of the polyphenylene sulfide composition of embodiment and comparative example:

[0042] According to the ratio of Table 1 / Table 2 / Table 3, put other components except glass fiber and calcium carbonate into the high-speed mixer and disperse evenly, then enter the twin-screw extruder, glass fiber and calcium carbonate are side-fed, extruded The polyphenylene sulfide composition was obtained by granulation; wherein, the temperatures of the four stages of extrusion were 290° C., 285° C., 280° C., and 280° C., and the screw speed was 350 rpm / min.

[0043] Related performance test methods:

[0044] Tensile strength: tested according to the standard ISO 527-2-2012, the tensile rate is 10mm / min;

[0045] Bending strength and flexural modulus: tested according to the standard ISO 178-2019, the bending rate is 2mm / min;

[0046] Gloss test: A general-purpose 60-degree gloss meter is used to test according to the standard ISO 2813-2014.

Abstract

The invention discloses a polyphenylene sulfide composition and a preparation method and application thereof. The polyphenylene sulfide composition comprises the following components in parts by weight: 35-50 parts of polyphenylene sulfide; 3-8 parts of glass fiber; 25-40 parts of calcium carbonate; 20-35 parts of a filler; and 0.1-1 part of a coupling agent. The glass fiber, the calcium carbonate and the fibrous or flaky filler are added into the polyphenylene sulfide resin and are matched with one another, meanwhile, a certain amount of coupling agent is added, so that the rigidity of the material can be effectively improved, a relatively good glossiness effect is kept, and the prepared polyphenylene sulfide material has excellent tensile strength and bending strength, is high in glossiness, and can meet the higher requirements on the material strength in the miniaturization and thin-wall development process of the automobile lamp reflecting cover.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a polyphenylene sulfide composition and its preparation method and application. Background technique [0002] Polyphenylene sulfide (PPS for short) has excellent high temperature resistance and dimensional stability, and is widely used in the field of automotive electronics. When used as the reflector material of automobile lights, the material is also required to have high rigidity and high gloss (if the surface gloss of the material is too low, there will be electroplating defects in the reflective layer during electroplating or bulges during electroplating at high temperature, so that The effect of the electroplating mirror surface is greatly reduced, causing the problem that the product is scrapped and cannot be used). At present, the rigidity of polyphenylene sulfide materials is mainly filled with glass fibers, and the content of glass fibers must be higher th...
