Problems solved by technology

[0003] However, the heat resistance of most plastics is poor, and it is easy to release the toxic substance bisphenol A when heated, and at high temperatures, oil stains are easy to adhere to the surface of the plastic, which not only reduces the quality of the plastic, but also makes the plastic unsightly
For this kind of plastic, if it is thermoplastic, it can also be recycled and reshaped; for thermosetting plastic, it can only be scrapped as a whole, and the cost is very high

Embodiment 1

[0034] A plastic surface treatment process, the specific steps are:

[0035] (1) Plastic degreasing: Use high-temperature lye to spray on the plastic surface at high pressure, and use a cleaning roller to brush the plastic surface to degrease.

[0036] (2) Plastic swelling: Put the degreased plastic into the swelling solution and soak for 5 minutes; the components in the swelling solution and the volume percentages of each component are: bentonite solution: 60%, ethyl acetate: 10%, Ethyl acetoacetate: 5%, the rest is distilled water.

[0037] (3) Plastic surface roughening: prepare microetching solution, each component in the microetching solution and the volume percentage of each component are: ammonium sulfate: 20%, barium sulfate: 25%, ammonium permanganate: 20%, oxalic acid: 20%, glycerin: 15%; soak the plastic in the microetching solution, raise the temperature of the microetching solution to 45°C at a rate of 10°C / min, and take it out after keeping it for 15 minutes; pr...

Embodiment 2

[0044] A plastic surface treatment process, the specific steps are:

[0045] (1) Plastic degreasing: Use high-temperature lye to spray on the plastic surface at high pressure, and use a cleaning roller to brush the plastic surface to degrease.

[0046] (2) Plastic swelling: Put the degreased plastic into the swelling solution and soak for 7 minutes; the components in the swelling solution and the volume percentages of each component are: bentonite solution: 63%, ethyl acetate: 12%, Ethyl acetoacetate: 8%, the rest is distilled water.

[0047] (3) Plastic surface roughening: prepare microetching solution, each component in the microetching solution and the volume percentage of each component are: ammonium sulfate: 22%, barium sulfate: 22%, ammonium permanganate: 22%, oxalic acid: 20%, glycerin: 14%; soak the plastic in the microetching solution, raise the temperature of the microetching solution to 50°C at a rate of 7°C / min, and take it out after keeping it for 17 minutes; pre...

Abstract

The invention relates to a plastic surface treatment technique which comprises the following steps: plastic degreasing, plastic swelling, plastic surface coarsening, primary grit blasting, spraying treatment, hole sealing treatment, secondary grit blasting (carrying out grit blasting on the plastic surface by using a high-pressure spray gun and a sand material), and water washing and drying. The treatment technique is simple, shortens the treatment time, and enhances the high-temperature oxidation resistance and corrosion resistance of the plastic; and the plastic has higher surface smoothness and is beautiful.

Description

technical field [0001] The invention belongs to the technical field of plastic surface treatment, and in particular relates to a treatment process capable of enhancing the high-temperature oxidation resistance and corrosion resistance of plastics. Background technique [0002] Plastics are polymer compounds that are polymerized from monomers as raw materials through addition polymerization or polycondensation reactions. Due to its light weight, good insulation, and low thermal conductivity, plastics are usually used to make daily necessities such as water cups, kettles, and milk bottles. [0003] However, the heat resistance of most plastics is poor, and it is easy to release the toxic substance bisphenol A when heated, and at high temperatures, oil stains are easy to adhere to the surface of the plastic, which not only reduces the quality of the plastic, but also makes the plastic Not beautiful. For this kind of plastic, if it is thermoplastic, it can also be recycled...
