Embodiment Construction

[0023] According to the volume ratio of 4:1, mix and stir the concentrated sulfuric acid solution with a mass fraction of 85% and acetic anhydride for 5 to 8 minutes to obtain a mixed solution, and then mix the zirconia ball milling beads and graphite according to the mass ratio of 17:1. In the ball mill, ball mill for 3 to 4 hours at a speed of 275 to 320r / min, then pass through a 100-mesh sieve to collect the sieved graphite powder; sieve the sieved graphite powder, mixed solution and high manganese in a mass ratio of 6:3:1 Potassium acid potassium was mixed and stirred for 32-40 minutes to obtain a reaction product, which was then put into a muffle furnace, expanded for 2-3 hours at a temperature of 1050-1100 ° C, cooled and discharged, and modified expanded graphite powder was obtained; Mix polyvinyl chloride and polyamide resin at a mass ratio of 3:1, heat up to 86-92°C to soften, and obtain a softened mixture, then add antimony trioxide and softened mixture with 3% mass o...

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, ...
