Embodiment 1

[0023] A preparation process for plastic recycled materials, comprising the steps of:

[0024] S1. Select waste plastics, remove impurities, wash, and crush to obtain waste plastic powder;

[0025] S2. Add the waste plastic powder, the resin mixture, and an appropriate amount of additives into the mixer, stir and mix to obtain a mixture;

[0026] S3, adding the mixture into the extruder to knead evenly, and then extruding;

[0027] S4, cooling the extruded product with cold water, and then drying;

[0028] S5, using a granulator to cut the product into a standard length;

[0029] S6. Screening, measuring, and packaging the cut products to obtain finished products.

[0030] The resin mixture is a mixture of ABS resin and PA resin, and the mass ratio of the ABS resin and PA resin is 1:1.

[0031] The mass ratio of the resin mixture to waste plastic powder is 1:2.

[0032] The auxiliary agent includes the following components in parts by weight: 10 parts of nano-titanium dio...

Embodiment 2

[0038] The difference from Example 1 is that: the mass ratio of the resin mixture to waste plastic powder is 1:3; the additives include the following components in parts by weight: 15 parts of nano-titanium dioxide, 15 parts of nano-titanium dioxide Silicon, 10 parts of glass fiber, 3 parts of antioxidant, 2 parts of dispersant, 2 parts of nucleating agent, 6 parts of lubricant, 15 parts of filler, 10 parts of glyceryl monostearate, 2 parts part of flame retardant, 3 parts of impact modifier, 40 parts of methanol solution; the stirring rate in the step S2 is 800rpm, the stirring time is 45min, and the stirring temperature is 50°C; the extrusion in the step S3 The outlet temperature is set to 180°C for the first stage, 180°C for the second stage, 190°C for the third stage, 195°C for the fourth stage, 195°C for the fifth stage, 220°C for the sixth stage, 220°C for the seventh stage, 225°C for the eighth stage, and 225°C for the machine head; In step S4, the product is cooled by ...

Embodiment 3

[0040] The difference from Example 1 is that: the mass ratio of the resin mixture to waste plastic powder is 1:4; the additives include the following components in parts by weight: 20 parts of nano-titanium dioxide, 20 parts of nano-titanium dioxide Silicon, 15 parts of glass fiber, 5 parts of antioxidant, 3 parts of dispersant, 3 parts of nucleating agent, 7 parts of lubricant, 20 parts of filler, 15 parts of glyceryl monostearate, 3 parts 5 parts of flame retardant, 5 parts of impact modifier, 50 parts of methanol solution; the stirring rate in the step S2 is 1000rpm, the stirring time is 30min, and the stirring temperature is 60°C; the extrusion in the step S3 The outlet temperature is set to 190°C for the first stage, 190°C for the second stage, 200°C for the third stage, 205°C for the fourth stage, 205°C for the fifth stage, 230°C for the sixth stage, 230°C for the seventh stage, 235°C for the eighth stage, and 235°C for the machine head; In step S4, the product is cooled...

Abstract

The invention discloses a plastic reclaimed material preparation process which comprises the following steps: S1, selecting waste plastic, removing impurities, cleaning and crushing to obtain waste plastic powder; s2, adding the waste plastic powder, the resin mixture and a proper amount of auxiliaries into a stirrer, and uniformly stirring and mixing to obtain a mixture; s3, adding the mixture into an extruder, uniformly mixing, and then extruding; s4, cooling the extruded product with cold water, and then drying; s5, cutting the product into a standard length by using a granulator; and S6, screening, metering and packaging the cut product to obtain a finished product. The whole process is simple, the process improvement cost is low, implementation is easy, the mechanical property of the product is improved by improving the formula of the regenerated material, and the product has good wear resistance, pressure resistance and heat resistance and has great economic value and social benefits.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a process for preparing recycled plastic materials. Background technique [0002] Plastic is a polymer compound (macromolecules) that is polymerized by addition polymerization or polycondensation reaction with monomer as raw material. It has medium resistance to deformation and is between fiber and rubber. Agents, lubricants, colorants and other additives. The main component of plastic is resin. Resin refers to a polymer compound that has not been mixed with various additives. The term resin was originally named after the lipids secreted by animals and plants, such as rosin and shellac. Resin accounts for about 40% to 100% of the total weight of the plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with no or few additives, such as p...
