The treatment process concretely comprises the following steps: firstly, respectively putting the plastic into an electrolytic ultrasonic cleaning machine, a pickling solution and an activating solution to carry out plastic pre-treatment; preparing a hardening layer; fitting the hardening layer; finally carrying out plastic post-treatment. The treatment process disclosed by the invention is simple and fast, the required treatment cost is low, and the glossiness is ensured when the surface hardness of the plastic is improved.
Description
Technical field
The invention belongs to frosting processing technology field, relate in particular to one and make frosting sclerosis, strengthen the treatment process of its hardness.
Background technology
Plastics are taking monomer as raw material, the macromolecular compound forming by addition polymerization or polycondensation polymerized.Because plastic material is light, good insulating, thermal conductivity be low, therefore plastics are usually used to make the daily necessitiess such as water tumbler, kettle, feeding bottle.
In recent years, along with the fast development of automotive industry, electrical industry and household electrical appliance industry, plastics are more and more frequent must being used in these fields also, therefore only have when the quality of plastics enough hard, and the enough lights of appearance, time attractive in appearance, the quality of guarantee product.In the conventional method, for the hardness on reinforced plastics surface, prevent from being scratched, conventionally first frosting is carried out to alligatoring, then plate metal level at frosting, but not only cost is higher and owing to having plated metal level for this kind of method, causes frosting glossiness deficiency.
Therefore, work out one and can make frosting sclerosis, strengthen its surface hardness, the treatment process that simultaneously ensures its surface gloss is the problem of the required research of those skilled in the art.
Summary of the invention
For addressing the above problem, the invention discloses a kind for the treatment of process of frosting sclerosis.
In order to achieve the above object, the invention provides following technical scheme:
A treatment process for frosting sclerosis, concrete steps are:
(1) plastics pre-treatment: first plastics are put into electrolysis supersonic cleaning machine and cleaned 5-10min, preparating acid washing lotion is with for subsequent use simultaneously; Plastics are taken out from electrolysis supersonic cleaning machine, put into the pickle solution preparing, pickle solution is warming up to 55-70 DEG C according to the speed of 5-10 DEG C/min, and be incubated 6-10min; Afterwards plastics are put into activation solution, and be aided with ultrasonic echography 20-30min; Be dried after having activated, for subsequent use;
(2) prepare hardened layer: according to the shape of plastics to be processed and the suitable injection mold of selection of dimension; Utilize the die sinking of high-low temperature controller control injection mold and heat up, injection mold being carried out to injection moulding after reaching injection temperature; Recycling subsequently high-low temperature controller carries out cooling to injection mold; Finally injection mold is carried out to die sinking, obtain hardening film, for subsequent use;
(3) hardened layer laminating: the hardening film obtaining in step (2) is moved on the plastics in step (1), position; After having located, utilize HVOF (High Velocity Oxygen Fuel) technology that hardening film is sprayed into frosting, and cooling forming;
(4) plastics aftertreatment: plastics are carried out to washing and drying.
The present invention is a kind of technique of carrying out hardening treatment at frosting.
First, plastics to be processed are put into electrolysis supersonic cleaning machine and carry out skimming treatment, in carrying out electrolytic degreasing, preparating acid washing lotion; After degreasing completes, plastics are put into the pickle solution preparing and carried out pickling, frosting is carried out to alligatoring; After alligatoring completes, put into activation solution and activate, be aided with ultrasonic echography, can accelerate molecular motion, frosting forms enough swell layer, has activated rear dry with for subsequent use.
Start subsequently to prepare hardened layer, the present invention adopts the method that plates again one deck hardening film at the outside surface of pending plastics to be used as the hardened layer of plastics outside surface, after prepared by hardened layer, first hardening film is positioned at plastics outside surface, by HVOF (High Velocity Oxygen Fuel) technology, hardening film is sprayed on again to the outside surface of plastics, the laminating of hardened layer after cooling forming.
Finally the plastics that process are carried out to washing and drying, complete plastics aftertreatment.
As preferably, the composition of the pickle solution of step (1) and the shared volume percent of each composition are respectively: permanganate: 45-50%, wetting agent: 45-50% and buffer reagent: 5-15%.
Permanganate can cause the pre-activation of frosting; Owing to comprising wetting agent in pickle solution, can play wetting action to plastics, and when solution PH is within the scope of slightly acidic, the pre-activation of permanganate is stronger, therefore the pH value of solution need to remain in slightly acidic, therefore in pickle solution, be also added with buffer reagent, avoid causing between permanganate and frosting molecule reacting, maintain the stable of pickle solution pH value.
As preferably, permanganate is potassium permanganate; Wetting agent is perfluorination wetting agent; Buffer reagent is sodium tetraborate.
As preferably, the activation solution in step (1) is that concentration is the chromic acid solution of 1-5g/L.
The present invention is compared with existing frosting hardening process, adopt pickle solution and the activation solution of rational proportion, and be aided with ultrasonic wave, the significantly alligatoring on reinforced plastics surface and activation effect, and hard by preparation quality, the good hardening film of glossiness is as the hardened layer of plastics outside surface.Therefore beneficial effect of the present invention is: (1) treatment process is simple and quick; (2) required processing cost is lower; (3) in promoting frosting hardness, ensured glossiness.
