Self-lubricating abrasion-resistant injection-molding grade molybdenum disulfide filled polyphenyl ether and preparation thereof

Abstract

The invention relates to an organic polymer composite material, more specifically, in particular to self-lubricating abrasion-resistant injection-molding grade molybdenum disulfide filled polyphenyl ether and a preparation technology thereof. The self-lubricating abrasion-resistant injection-molding grade molybdenum disulfide filled polyphenyl ether comprises the following components according to weight ratio: 30-80% of polyphenyl ether powder, 5-40% of nylon 66 powder, 1-35% of molybdenum disulfide powder, 0.3-1.5% of antioxidant, 0.1-3.0% of heat stabilizer, 0.1-2.8% of coupling reagent, 0.1-3.0% of HMW (high molecular weight) silicone oil, 1-5% of compatilizer and 0.3-5.5% of other auxiliaries. According to the self-lubricating abrasion-resistant injection-molding grade polymer molybdenum disulfide filled polyphenyl ether and the preparation technology thereof, better self-lubrication and abrasion resistance are obtained simultaneously on a basis of keeping the original advantages of polyphenyl ether; raw materials for production are convenient to purchase; and the raw and auxiliary materials, additives and production equipment are all domestic, so that the production cost and raw material cost are largely lowered, therefore the comprehensive competitive power of products is effectively improved.

Description

technical field [0001] The invention relates to an organic polymer composite material, and more specifically relates to a self-lubricating wear-resistant injection molding grade molybdenum disulfide-filled polyphenylene ether and a manufacturing process thereof. Background technique [0002] Polyphenylene ether is a thermoplastic engineering plastic that can withstand higher temperatures. It has a low relative density and a small water absorption rate. It can self-extinguish after leaving the fire and has good mechanical and electrical properties in a wide temperature range; glass The melting temperature is the highest among thermoplastics, and the creep resistance at high temperature is also the best among all thermoplastic engineering plastics; the molding shrinkage rate and thermal expansion coefficient are small, the size is stable, and it is suitable for the manufacture of precision products; it has excellent acid and alkali resistance and resistance The characteristics...
