Preparation method of modified resin-based engineering plastic

Abstract

The invention discloses a preparation method of modified resin-based engineering plastic and belongs to the technical field of preparation of plastics. The preparation method of the modified resin-based engineering plastic, disclosed by the invention, has the benefits that polyvinyl chloride is mixed with polyamide resin to obtain mixed resin, the mixed resin is modified with antimony trioxide andred phosphorus, and then graphite powder is modified with a concentrated sulfuric acid solution, and is blended with acetic anhydride and potassium permanganate, and thus, expanded graphite powder isprepared at high temperature; the expanded graphite powder is a carbon source in an expansion system, also is a heat insulating layer and can exert an obvious heat insulating effect; steel fibers areadded in a resin base material, interlaced resin base material molecular chains are connected among the steel fibers, and the steel fibers are taken as a filler to modify engineering plastic; a layerof coconut oil is continuously smeared in an engineering plastic blank, so that the further corrosion is prevented, and the service life of the engineering plastic is prolonged; and a formula is goodin stability and has a long-lasting corrosion inhibition ability, thereby improving the corrosion resistance of the engineering plastic and having a wide application prospect.

Description

technical field [0001] The invention discloses a preparation method of modified resin-based engineering plastics, belonging to the technical field of plastics preparation. Background technique [0002] Engineering plastics refer to industrial plastics used as industrial parts or housing materials, which are plastics with excellent strength, impact resistance, heat resistance, hardness and aging resistance. The Japanese industry defines it as a high-performance plastic that can be used for construction and mechanical parts, with a heat resistance above 100°C, and is mainly used in industry. [0003] Compared with general-purpose plastics, engineering plastics can meet higher requirements in terms of mechanical properties, durability, corrosion resistance, heat resistance, etc., and are more convenient to process and can replace metal materials. In recent years, engineering plastics have been widely used in electronics, automobiles, construction, office equipment, machinery, ...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention: in view of the poor thermal conductivity, poor impact resistance and poor flame retardancy of common engineering plastics, and the poor chemical corrosion resistance of metals, when the metal on the surface of engineering plastics is corroded, its glossiness will be greatly reduced , which seriously affects the aesthetic feeling of its appearance and cannot meet the requirements of the material market, provides a method for preparing modified resin-based engineering plastics
