Abstract

The invention relates to a polyphenylene sulfide (PPS) resin composition and application thereof. The polyphenylene sulfide resin composition comprises the following components by mass percentage: 20-65% of PPS resin, 20-60% of glass fiber, 0.1-3% of a dispersing agent, 0.5-10% of a stress releasing agent, 0.3-2.0% of an antioxidant, 0.5-3.0% of a lubricating agent and 0.5-10% of a filling agent.According to the invention, the stress releasing agent is added into a PPS-glass fiber composition system, so that partial crystallization regularity of PPS is destroyed, also the free space volume among PPS molecules is also increased, and timely release of thermal stress and mechanical stress generated in the material processing process is facilitated; furthermore, all the components of the resin composition are compounded according to a specific proportion, so that the problem of large internal stress of the glass fiber reinforced PPS engineering plastic is effectively solved, the stabilityof an electroplated circuit is improved, and meanwhile, good mechanical properties, dielectric properties and processability are maintained.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a polyphenylene sulfide resin composition and its application. Background technique [0002] Antenna vibrator is a component and functional part in a communication base station. Its main function is to guide and amplify electromagnetic waves, so that the electromagnetic signal received by the antenna is stronger. It is an important component of the antenna. It is used in a large amount in the antenna, and the general structural design complex. The traditional manufacturing process of the antenna vibrator is die-casting of metal materials (aluminum alloy or zinc alloy). However, due to the complex structure of the antenna vibrator, the use of metal materials has many machining and forming processes, which is difficult and the accuracy is difficult to guarantee, resulting in product production costs. High; and the density of the metal material is high, and the mass of...
