Description
Technical field
The invention belongs to frosting processing technology field, be specifically related to a kind of technique for treating plastic surface that can improve the clean and antibacterial ability of frosting.
Background technology
Plastics are to take 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, so plastics are usually used to make the daily necessitiess such as water tumbler, kettle, feeding bottle.
In use, owing to can depositing the liquid of different sorts and differing temps in plastics, so frosting extremely easily produces dirt breed bacteria, and is difficult to bactericidal cleaning.
The method of existing reinforced plastics surface cleaning ability and antibacterial ability is generally: the easy cleaned metal level of plated surface last layer at plastics, is then coated in layer on surface of metal for antibacterial by antibacterial coating liquid.But this kind of method exists obvious defect, once the metal level of frosting comes off, the cleaning capacity of plastics and antibacterial ability all can be subdued.
Therefore, develop a kind of can improve respectively frosting clean with the treatment process of antibacterial ability be 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 that improves plastic cleaning antibacterial ability.
In order to achieve the above object, the invention provides following technical scheme:
Improve a treatment process for plastic cleaning antibacterial ability, concrete steps are:

(2) plastics activation: plastics are soaked in the admixture activation liquid of chromic acid and the vitriol oil, soak duration 3-5min;
(3) plastics alligatoring: preparation micro-etching solution, plastics plastics are immersed in micro-etching solution, according to the speed of 5-10 ℃/min, micro-etching solution is warming up to 55-65 ℃, and takes out after being incubated 15-20min; Preparation neutralizer, is warming up to 65-70 ℃ by neutralizer, and plastics are put into neutralizer, after immersion 5-10min, takes out; Finally plastics are put into after supersonic cleaning machine cleans 15-20min and taken out;
(4) prepare antibacterial plastic concentrate: separately get plastics and carry out melting, add respectively nano-silver powder, tackiness agent and lubricant, after stirring, be extruded into antibacterial granule with standby;
(5) oxydizing flame is processed: plastics are placed on oxydizing flame and are calcined 2-4 time, calcine duration 2-4s at every turn, calcining duration reduces along with the growth of calcining number of times;
(6) antibiotic layer spraying: utilize HVOF (High Velocity Oxygen Fuel) technology the antibacterial granule in step (4) to be evenly sprayed on to the surface of plastics, and cooling;
(7) modification coating: plastics are carried out after physical vapor deposition plasma modification, then carry out physical vapor deposition metallic chromium layer;
(8) wetting ability is processed: plastics are carried out to the processing of atmospheric plasma aura;
(9) washing and drying.
First method provided by the invention carries out skimming treatment to plastics, and the impurity of frosting and grease are cleaned; Subsequently plastics are activated and alligatoring, frosting is carried out to pre-treatment, be convenient to the subsequent disposal of plastics.
The antibacterial plastic concentrate of preparing afterwards plastic outer layer, separately gets plastics and carries out melting, stirs after adding nano-silver powder, tackiness agent and lubricant, is extruded into antibacterial granule; The composition of antibacterial granule also has nano-silver powder except plastics, and silver, when having anti-microbial property, also shows excellent over-all properties and barrier property, has good flame retardant effect; And the matter of silver is soft, easy to process.
After antibacterial granule completes, plastics are carried out to oxydizing flame processing, make its temperature in critical heat distortion, so that later use HVOF (High Velocity Oxygen Fuel) technology is evenly sprayed on the antibacterial granule of making the surface of plastics, complete the spraying of antibiotic layer.
