Abstract
The invention discloses a polyphenylene sulfide/polyether sulfone wear-resistant composite board, which belongs to the technical field of material processing and comprises the following raw materials in parts by weight: 100-150 parts of polyphenylene sulfide, 80-120 parts of polyether sulfone, 8-15 parts of polytetrafluoroethylene, 3-8 parts of crystalline flake graphite, 10-18 parts of silicon oxide and 6-12 parts of molybdenum disulfide. The polyphenylene sulfide/polyether sulfone wear-resistant composite board is prepared in a melt blending mode. The mechanical test result shows that compared with other modifiers, the crystalline flake graphite can obviously improve the flexural modulus of the material and has the best comprehensive performance. The thermal analysis result shows that compared with other modifiers, the crystalline flake graphite has smaller influence on the thermal stability of the composite material, and can keep the high heat resistance of the polyphenylene sulfide/polyether sulfone wear-resistant composite board. The friction test and the microscopic observation result show that the friction coefficient is lowest, the abrasion of the material is mainly adhesive abrasion, and the mechanical property and the friction property are both considered.
Description
Technical Field
The invention belongs to the technical field of material processing, and particularly relates to a polyphenylene sulfide/polyether sulfone wear-resistant composite board and a preparation method thereof.
Background
The polyphenylene sulfide is a high-crystallinity thermoplastic special engineering plastic, the main chain of the molecule of the material is composed of rigid benzene rings and flexible sulfur atoms which are alternately arranged, and the molecular structure is symmetrical, so that the PPS has excellent corrosion resistance, flame retardance, dimensional stability, adhesiveness and easy processability. Is expected to be widely applied in the fields of electronics, electrics, automobiles, machinery, aerospace, chemical engineering and the like. However, pure PPS has the problems of large brittleness, poor toughness, high mold temperature required in the molding process, unstable viscosity in the melting process, easy oxidation and crosslinking in air under high temperature conditions and the like.
The polyether sulfone is prepared by condensing 4, 4-bis sulfonyl chloride diphenyl ether with diphenyl ether under the catalysis of anhydrous ferric chloride, is an amorphous polymer, and is a thermoplastic engineering plastic. The coating has excellent comprehensive properties such as heat resistance, hot water resistance, creep resistance, dimensional stability, impact resistance, chemical resistance, no toxicity, flame retardance and the like, so the coating is widely applied to the fields of electronics, electric appliances, machinery, automobiles, medical appliances, food processing, non-stick coatings and the like for a long time.
With the continuous improvement of the requirements of people on the wear resistance of materials, the polyphenylene sulfide and polyether sulfone composite material which is not subjected to wear resistance modification is difficult to meet the requirements, so that the wear resistance modification of polyether sulfone becomes necessary. The existing wear-resistant modification treatment methods for the composite material of the polyphenylene sulfide and the polyether sulfone are various in types and good in modification effect, and particularly with the appearance and application of nano materials, the wear resistance of the composite material of the polyphenylene sulfide and the polyether sulfone is remarkably improved, so that the polyether sulfone can be widely used in more fields, but the defects exist. The nano material has the advantages of good wear-resistant reinforcing effect and small addition amount, but also has the defects of difficult dispersion, high cost and the like. In the process of wear-resistant modification, the wear-resistant effect of the nano material can be influenced due to uneven dispersion of the nano material, and the obtained composite material has low wear resistance and causes adverse effects on the production and application of the composite material.
