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.

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:
Die surface can greasy dirt be attached to die surface because of wearing and tearing perhaps after when mould of plastics uses one section; Can cause the quality product and the outward appearance of die production all defective like this; Owing to be mould of plastics, it is easy to the oxidation that is corroded in producing, and product appearance does not reach specification of quality; Mould can only integral body be scrapped processing, and cost is very big.
Summary of the invention:
Be exactly that the present invention provides a kind of anti-oxidant erosion-resisting mould of plastics surface treatment method to the problems referred to above.
For realizing above-mentioned purpose, the present invention adopts following technical scheme, may further comprise the steps:
(1) adopt blasting craft that the mould of plastics outside surface is carried out sand blasting; Blasting craft adopts air compressor machine, its sandblast blast>=12Kg/cm
2, the sand material is the nanometer grade silica of 2-10nm for a diameter;
Said nanometer grade silica preparation method is: the nanometer grade silica mixing solutions at 0 ℃ of following stir-activating 4 h, is added sodium lauryl sulphate, 6 * 10
4R/min high-shear 4 h, reaction soln are cooled to decompress filter after the room temperature, and gained is deposited under 100 ℃ and is dried to constant weight, obtains nanometer grade silica.
(2) mould is carried out thermal pretreatment: the thermal pretreatment temperature is carried out the processing of metallize, sintering metal and indissoluble material with air gun to the mould bottom surface between 100 ℃, metallic substance is zinc, aluminium, magnesium, silver or metal alloy; Spray deposit is carried out 15 times;
(3) through the HVOF technology with the powder spraying of resistance to high temperature oxidation and corrosion resistance nature material on mould of plastics: said powder is the pure nickel powder, contain 30% Al
2O
3With the powdered alloy of 70% nickel, contain 70% nickel and 40% chromium, contain 80% titanium and 20% nickel powdered alloy or in one or more arbitrary combination;
(4) carry out surface-sealing through the metallize layer: with air gun the processing of metallize, sintering metal and indissoluble material is carried out in the mould bottom surface, used identical of metallic substance and second step;
(5) integral surface carries out sandblasting: adopt high-pressure spray gun that mould of plastics is handled, 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 silica sand and granulated glass sphere compound;
(6) subsequent disposal: mould is placed more than 15 hours in the physical environment air, and the oven temperature when in baking oven, being heated to this mould of plastics production specific product takes out mould of plastics, places air to be cooled to room temperature.
Silica sand: granulated glass sphere=1:2, silica sand diameter are 0.25 μ m, and the granulated glass sphere diameter is 0.55 μ m.
Adopt corundum sand or chilled iron shot in the blasting craft.
Said metal layer spraying is handled and is adopted the pure metal silk.
Beneficial effect of the present invention:
The present invention sprays the oxidation and corrosion layer can play the surface of good defense reaction to the mould of plastics online production; And can not produce any negative impact to productive temp, especially whole sandblast silica sand and glass sand compound are handled, and be with low cost; Easy and simple to handle; And need not to carry out other processing after injection finishes, can guarantee the mould of plastics surface gloss, promote product specification.
