Embodiment 1

[0029] (1) Polyphenylene sulfide (Toray, Japan, average weight average molecular weight 50,000), nylon 6 (Shanghai BASF), compatibilizer (maleic anhydride grafted ethylene-octene copolymer POE-g-MAH, USA Dow), hexafluorodianhydride (Shanghai Merrill Chemical Company), antioxidant (1010, Jiangsu Aikang Biology), lubricant (ethylene bisstearic acid amide, Qingdao Jisi Polymer Company) after drying, in Stir evenly in a high-speed mixer, melt and extrude the mixture through a twin-screw extruder, cool it in a water tank and cut it into pellets through a pelletizer. After drying, the polyphenylene sulfide / nylon 6 composite material is obtained.

[0030] The mass ratio of polyphenylene sulfide, nylon 6, compatibilizer, hexafluorodianhydride, antioxidant and lubricant is 100:30:4:0:0.1:0.1. The interval temperatures of the twin-screw extruder were 290, 310, 310, 310, 310, and 300° C., and the screw speed was 50 rpm.

[0031] (2) The above-mentioned pellets were dried, and prepared ...

Embodiment 2

[0033] According to the preparation process of Example 1, wherein the mass ratio of polyphenylene sulfide, nylon 6, compatibilizer, hexafluorodianhydride, antioxidant, and lubricant is 100:30:3:1:0.1:0.1, poly Phenylsulfide / Nylon 6 Standard Spline. (that is, the total mass content percentage of compatibilizer and hexafluorodianhydride remains unchanged, and the ratio of the two is changed, the same below)

Embodiment 3

[0035] According to the preparation process of Example 1, wherein the mass ratio of polyphenylene sulfide, nylon 6, compatibilizer, hexafluorodianhydride, antioxidant, and lubricant is 100:30:2:2:0.1:0.1, poly Phenylsulfide / Nylon 6 Standard Spline.

Abstract

The invention relates to the technical field of high polymer materials, in particular to a polyphenylene sulfide / nylon 6 composite material and a preparation method thereof. The polyphenylene sulfide / nylon 6 composite material is prepared from polyphenylene sulfide, nylon 6, a compatilizer and hexafluorodianhydride according to the mass ratio of 100:(30-50):(2-5):(1-3), the raw materials are dried, mixed, subjected to melt extrusion, water-cooled and granulated, and the composite material is obtained. According to the invention, hexafluorodianhydride is used as a co-compatibilizer of polyphenylene sulfide and nylon 6, because both ends of hexafluorodianhydride molecules contain anhydride groups, the hexafluorodianhydride molecules can react with polyphenylene sulfide and nylon 6 to improve the compatibility of the polyphenylene sulfide and the nylon 6, and meanwhile, hexafluorodianhydride is white powder containing rigid groups, and is uniformly dispersed in a matrix to play a role of a nucleating agent to reduce spherocrystals, and a rigid particle strengthening and toughening effect is achieved. The hexafluorodianhydride contains a large amount of fluorine atoms with relatively large electronegativity, so that the hexafluorodianhydride can play a role of a lubricant, and is beneficial to demolding of polyphenylene sulfide and nylon 6 products.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyphenylene sulfide / nylon 6 composite material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (PPS) is a special engineering plastic with excellent heat resistance, corrosion resistance, radiation resistance and flame retardancy, but it has defects such as brittle material, low elongation at break, and high price. Nylon is the engineering plastic with the largest amount. Nylon 6 (PA6) is widely used in nylon series. It has excellent mechanical properties, wear resistance, self-lubricating properties and low price. Adding PA6 to PPS as a dispersed phase can To achieve the purpose of reducing costs and improving resilience. [0003] In order to improve the compatibility between polyphenylene sulfide / nylon 6, use maleic anhydride compatibilizers such as maleic anhydride grafted SEBS, maleic anhydride grafted ethylene-octene copol...
