The molecular structure of the polyphenylene sulfide is that benzene rings are alternately connected with sulfur atoms at para positions, and molecular chains have high rigidity and regularity, so the polyphenylene sulfide is a crystalline polymer, and the highest degree of crystallinity can reach 70-80%. Therefore, the pure polyphenylene sulfide material has high rigidity but poor toughness, so that the application field of the pure polyphenylene sulfide material with high product toughness requirement is limited, and the toughening modification of the polyphenylene sulfide material is an important means for widening the application field of the material.
The invention discloses a high-toughness polyphenylene sulfide reinforced composite material and a preparation method thereof (CN 106243719A). The invention can inhibit the generation of carbide in the preparation process and improve the compatibility between used resins, and the polyphenylene sulfide composite material prepared by the invention has high impact strength, excellent strength and extensibility at a welding line and high formability.

The polyphenylene sulfide material has good flame retardant property, so that a good flame retardant effect can be achieved only by adding a small amount of flame retardant, and the polyphenylene sulfide material has the characteristics of high rigidity, good dimensional stability, excellent chemical resistance, excellent electrical performance and the like, so that the polyphenylene sulfide material has a wide application prospect in the flame retardant material market. But the application range of the polyphenylene sulfide is limited by the defect of poor toughness of the polyphenylene sulfide, the impact resistance of the polyphenylene sulfide material can be further reduced by adding the flame retardant, the processing flow property of the polyphenylene sulfide material can be reduced to a certain extent by the traditional toughening means, and the molding of products with complicated structures or thinner wall thickness is not facilitated. Therefore, the market is in need of developing a polyphenylene sulfide material which has high flame retardant property, high toughness and high fluidity.

The composite materials prepared in the above examples and comparative examples were injection molded into test standard bars in standard sizes, wherein the notched impact strength test standard bar size: the length is 80mm, the width is 10mm, the thickness is 4mm, the residual width at the bottom of the gap is 8mm, and the radius at the bottom of the gap is 0.1 mm; fire rating test standard spline size: 125mm in length, 13mm in width and 1.6mm in thickness; melt flow rate test: a sample of particles. The correlation performance was tested with reference to the following criteria:
1. testing the notch impact strength according to the GB/T1043 standard;
2. the fire rating is tested according to ANSI/U L94 standard;
3. the melt flow rate was measured according to the GB/T3682 standard.
The test results of the above examples and comparative examples are shown in table nine:
watch nine
In summary, it can be seen from table nine that in comparison with comparative example 1, in comparison with comparative example 2, in comparison with comparative example 3, in example 5, the addition of the low molecular weight polymer plasticizer in the presence of the toughening agent significantly improves the notched impact strength of the polyphenylene sulfide composite material, i.e., increases the toughness of the material, which indicates that the low molecular weight polymer plasticizer and the toughening agent generate a synergistic effect. In addition, the addition of the low molecular weight polymer plasticizer also greatly improves the melt flow rate of the polyphenylene sulfide composite material, namely endows the material with good processing flow property.
The comparative examples 2 to 4 can find that the notch impact strength and the melt flow rate of the polyphenylene sulfide composite material are gradually increased along with the increase of the content of the low molecular weight polymer toughening agent under the premise that the proportion of other components is not changed, and the improvement range of the notch impact strength of the material is smaller by continuously adding the low molecular weight polymer plasticizer after the content of the oligomer plasticizer exceeds 3 percent, so that the polyphenylene sulfide composite material has a more ideal toughening effect when the content of the low molecular weight polymer plasticizer is 3 percent.
It can be seen from comparison of examples 1, 2 and 5 that the polyphenylene sulfide composite material corresponding to the same content of low molecular weight polyethylene as the low molecular weight polymer plasticizer is better in both notched impact strength and melt flow property than the polyphenylene sulfide composite material corresponding to the low molecular weight polystyrene or the low molecular weight polyethylene glycol ether as the low molecular weight polymer plasticizer.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
