Abstract
The invention relates to a method for processing the surface of a plastic mould and especially relates to an anti-corrosion oxidation-resisting method. The invention provides an anti-corrosion oxidation-resisting method for processing the surface of the plastic mould. The method comprises the following steps: performing sand blasting cleaning treatment on the outer surface of the plastic mould according to a sand blasting technology; performing preheating treatment on the mould; spraying and coating powder of a high-temperature-resisting anti-corrosion material onto the plastic mould according to a high-speed flame spraying technology; sealing holes in the surface by coating a metal layer; performing sand blasting treatment on the whole surface; and performing subsequent treatment. The glossiness of the surface of the plastic mould is ensured and the grade of the products is increased.
Description
technical field:
The present invention relates to a kind of mould of plastics surface treatment method, relate in particular to the method for anticorrosion, antioxidation.
background technology:
When mould of plastics is used one section, rear mold surface can be attached to die surface because of wearing and tearing or greasy dirt, can cause like this quality product and the outward appearance of die production all defective, owing to being mould of plastics, its oxidation that is easy to be corroded in producing, and product appearance does not reach specification of quality, mould can only integral body be scrapped processing, and cost is very large.
summary of the invention:
Be exactly for the problems referred to above, the invention provides a kind of anti-oxidant erosion-resisting mould of plastics surface treatment method.
For achieving the above object, the present invention adopts following technical scheme, comprises the following steps:
(1) adopt blasting craft to carry out sand blasting to mould of plastics outside surface; Blasting craft adopts air compressor machine, its sandblast blast>=12Kg/cm
2, the nanometer grade silica that sand material is 2-10nm for a diameter;
Described nanometer grade silica preparation method is: by nanometer grade silica mixing solutions stir-activating 4 h at 0 ℃, add sodium lauryl sulphate, 6 * 10
4r/min high-shear 4 h, reaction soln is cooled to decompress filter after room temperature, and gained is deposited at 100 ℃ and is dried to constant weight, obtains nanometer grade silica.
(2) mould is carried out to thermal pretreatment: thermal pretreatment temperature, between 100 ℃, is carried out the processing of metallize, sintering metal and indissoluble material to mould bottom surface with air gun, metallic substance is zinc, aluminium, magnesium, silver or metal alloy; Spray deposit is carried out 15 times;
(3) by HVOF (High Velocity Oxygen Fuel) technology by the powder spraying of resistance to high temperature oxidation and corrosion resistance nature material on mould of plastics: described powder is pure nickel powder, contain 30% Al
2o
3with the powdered alloy of 70% nickel, the chromium that contains 70% nickel and 40%, contain 80% titanium and 20% nickel powdered alloy or in one or more arbitrary combination;
(4) by metallize layer, carry out surface-sealing: with air gun, mould bottom surface is carried out the processing of metallize, sintering metal and indissoluble material, identical used with second step of metallic substance;
(5) integral surface carries out sandblasting: adopt high-pressure spray gun to process mould of plastics, nozzle diameter is 1.5mm, jet length die surface 220-280mm, and the speed of moving horizontally is 0.05m/s, sand-blast material is quartz sand and granulated glass sphere compound;
(6) subsequent disposal: mould is placed more than 15 hours in physical environment air, the oven temperature while being heated to this mould of plastics production specific product in baking oven, takes out mould of plastics, is placed in air and is cooled to room temperature.
Quartz sand: granulated glass sphere=1:2, quartz sand diameter is 0.25 μ m, granulated glass sphere diameter is 0.55 μ m.
In blasting craft, adopt corundum sand or chilled iron shot.
Described metal layer spraying is processed and is adopted pure metal silk.
Beneficial effect of the present invention:
The present invention sprays oxidation and corrosion layer can play good surperficial defense reaction to mould of plastics online production, and can not produce any negative impact to productive temp, especially whole sandblast quartz sand and glass sand compound are processed, with low cost, easy and simple to handle, and after spraying, without carrying out other, process, can guarantee mould of plastics surface gloss, improving product class.
