Self-lubricating abrasion-resistant injection-class molybdenum disulfide-filled high-temperature nylon and preparation technique thereof

Abstract

The invention relates to an organic high-polymer composite material, in particular to a self-lubricating abrasion-resistant injection-class molybdenum disulfide-filled high-temperature nylon and a preparation technique thereof. The nylon consists of the following components in proportion by weight: 87 percent to 95 percent of high-temperature nylon; 0.1 percent to 2.5 percent of high-molecular weight silicone oil; 1 percent to 15 percent of molybdenum disulfide powder; 0.3 percent to 1.5 percent of antioxidant; 0.1 percent to 2.0 percent of coupling agent; and 0.3 percent to 5.5 percent of other additives. A product which is made of the nylon by way of injection moulding can be automatically demoulded, release agent does not need to be used, consequently, no cyclophane cyanogen contained in the release agent is left on the product, and thereby the production is more environment-friendly; moreover, the used materials can be conveniently produced and purchased, domestic materials, additives and production equipment are adopted, consequently, the production cost and the material cost are greatly reduced, and thereby the comprehensive competitiveness of the product is effectively enhanced.

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 high-temperature nylon and a preparation method thereof. Background technique [0002] At present, the application of replacing natural materials with plastics continues to expand internationally. Scientists around the world are actively looking for new high-performance thermoplastics to replace metal and wood through various experiments. important parts of. [0003] The development of high-temperature-resistant nylon makes it possible to miniaturize, lighten, and strengthen power for industrial, agricultural and civil facilities. High-temperature nylon can bring higher temperature resistance to some parts, or simply replace metal raw materials to produce these parts. There is also a trend to replace metal and thermoset materials with high-temperature nylon for devices a...

Problems solved by technology

However, the current social technology is developing rapidly, changing with each passing day, and a large number of new products and new inventions are pouring out. For parts that require a greatly reduced friction coefficient and the raw material itself is extremely wear-resistant, the many advantages of ordinary high-temperature nylon make the design People are very fond of it, but the shortcoming of its own lack of wear resistance is a headache

This shortcoming greatly limits the application range of high-temperature nylon. At the same time, since many release agents contain polycyclic aromatic cyanides, which are currently strictly restricted components in many environmental protection requirements, the most direct way to ensure safety is that the raw materials themselves are easy to Mold release, no need to use a release agent
