Problems solved by technology

For example, the invention patent with the patent application number 2011104296487 discloses a high-strength PPS material. 0.2-0.5 part of oxygen agent, 0.5-1 part of coupling agent, the strength of polyphenylene sulfide (PPS) can be improved by adding glass fiber to polyphenylene sulfide (PPS), and the slider made of it can be used In the small sizing machine, the service life of the slider has been extended to a certain extent compared with other materials, but in the large sizing machine, the slider needs to bear a greater force, and its strength still cannot fully meet this requirement. Extremely high occasions of use
In addition, since the slider has to go through multiple frictions, and the material with better insulation is more likely to generate static electricity, the slider is also easier to generate static electricity during the working process, a large amount of static electricity will cause electric shock, and there are more flammable products Fires are prone to occur in the workshop, causing safety hazards to production personnel

Abstract

The invention discloses a microcrystalline graphite-containing PPS (polyphenylene sulfide) composite material. The microcrystalline graphite-containing PPS composite materiel solves the problems that sliding blocks manufactured by adopting the PPS composite material in the prior art have poor wear-resisting performance and poor anti-static performance. According to the key points of the technical scheme, the microcrystalline graphite-containing PPS composite materiel comprises 25-50 parts of PPS, 15-50 parts of glass fibers, 5-30 parts of microcrystalline graphite, 1-2 parts of coupling agent, 0.5-2 parts of anti-static agent and 0.5-1 part of antioxidant. The wear-resisting performance and anti-static performance of the sliding blocks manufactured by adopting the microcrystalline graphite-containing PPS composite materiel disclosed by the invention are greatly improved so that the sliding blocks can be applied under various harsh conditions, and the service life of the sliding blocks is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of special engineering plastics, more specifically, it relates to a PPS composite material containing microcrystalline graphite and a preparation process thereof. Background technique [0002] Wear-resistant sliders are required in the sizing machine of textile machinery. For example, the patent No. ZL2009101925761 discloses a sizing machine, which includes a shoe rack, a sizing treatment box, a chain, an upper guide rail and a lower guide rail, and a shoe rack. Both ends are movably installed on the chain respectively. The movement route of the chain is approximately square. Sliders are installed at both ends of the shoe rack. The sliders are square and surrounded by a smooth plane. The sliders are movably connected to the chain and outside the vertical movement route of the chain. Install the slide bar at the corresponding slide block. When the setting machine is in operation, the slider needs to do recip...
