Abstract
The invention discloses a kind of mould of plastics method for anticorrosion treatment: (1) removes impurity and the greasy dirt on mould of plastics surface；(2) being put into by above-mentioned mould in the mono-acid solution of pH value≤5 and carry out pickling, pickling temperature is 75-80 DEG C, and pickling time is the 20-25 second；(3) impregnating fluid sprayed or brush on the surface of above-mentioned mould, forming anticorrosive coat；(4) mould being attached with anticorrosive coat is put in the baking oven of 100-120 DEG C and toast；(5) take out mould, complete the preservative treatment of mould of plastics.The present invention prepares simple, with low cost, environmental protection, can significantly improve the corrosion resistance of mould, extends the mold work life-span.
Description
Technical field
The present invention relates to mould production technical field, be specifically related to a kind of mould of plastics method for anticorrosion treatment.
Background technology
Plastic is in forming process, and the composition such as PVC or PEC in plastics can decomposite corrosive gas after being heated,
Mould is caused chemical attack effect.At present, structural change method, protective layer method, electrochemical protection method are all conventional plastics moulds
Tool anticorrosion means, these means all have preferable anticorrosive property, but structural change method cost is high；The preparation of protective layer method is multiple
Miscellaneous, toxicity is high；Electrochemical protection method high energy consumption, high pollution shortcoming the most prominent.
Summary of the invention
It is an object of the invention to provide a mould of plastics method for anticorrosion treatment, the method for the technical problem of above-mentioned existence
Prepare simple, with low cost, environmental protection, the corrosion resistance of mould can be significantly improved.
The present invention realizes above-mentioned technical purpose and is adopted the technical scheme that: a kind of mould of plastics method for anticorrosion treatment, bag
Include following steps:
(1) impurity and the greasy dirt on mould of plastics surface are removed；
(2) being put into by above-mentioned mould in the mono-acid solution of pH value≤5 and carry out pickling, pickling temperature is 75-80 DEG C, pickling time
For the 20-25 second；
(3) impregnating fluid sprayed or brush on the surface of above-mentioned mould, forming anticorrosive coat；
(4) mould being attached with anticorrosive coat is put in the baking oven of 100-120 DEG C and toast；
(5) take out mould, complete the preservative treatment of mould of plastics.
Further, the mono-acid solution described in step (2) refers to the H that mass concentration is 12%2SO4Solution.
Further, in the impregnating fluid described in step (3), the mass ratio of each raw material is: ethylene glycol: dioxolane: fluorine
Change carbon: water=1-1.5:1-1.5:3-3.5:3.5-5.
Further, the baking time described in step (4) is 30-45 minute.
Beneficial effect: the present invention prepares simple, with low cost, environmental protection, can significantly improve the corrosion resistance of mould, prolong
The long mold work life-span.
Detailed description of the invention
