Description
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of antibacterial and mouldproof pump valve proprietary powder coatings.
Background technology
In recent years, the application of powder coating has surmounted water-borne coatings and high solid coating etc. in coatings industry, becomes industry member and uses one of more coating variety.Powder coating process solves the problems such as inflammable, the explosive and contaminate environment existing for traditional paint coating process, and its coating possesses superior performance, the recyclable use again of raw material, and coating process is simple.Pump can be widely used in, valve housing is coated with and loads onto.Because pump valve is foundry goods or forging, therefore its surface irregularity, also certain defect is there is in currently available technology for the functional powder coating technology of valve surface process, cause coating to occur the defects such as shrinkage cavity, pinprick and serious orange peel shape, and then cause pump valve to be restricted in special dimension application such as food, biology, pharmacy, chemical industry, space flight and electronics.And most of pump valve all can be used in the factor such as the media environment impact of High water cut, Gao Hansha, deep-etching, increase the weight of the corrosion of pump valve, easier fouling on pump valve, thus cause pump valve short for work-ing life, the problem that round of visits is short, workload is large, make troubles to use, general surface intensified technique mainly contains metal plating, ceramic coating, some other coating, although slow down wearing and tearing to a certain extent, improve erosion resistance, but all there is weak point: the easy layering of metal plating causes coming off; Pottery shock resistance is poor, easy chipping phenomenon; Some polymeric coating mechanics and thermal characteristics difference etc.Thus research and development have the powder coating of the functions such as weather-proof, water-tight corrosion-proof, and possess skills the meaning promoting to improve with industry.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of antibacterial and mouldproof pump valve proprietary powder coatings.
The present invention is achieved by the following technical solutions:
A kind of antibacterial and mouldproof pump valve proprietary powder coatings, is made up of the raw material of following weight part: hydroxy polyester resin 52-54, fluorocarbon resin 7-8, isocyanuric acid three-glycidyl ester 4-5, nano-aluminium oxide 13-15, perfluoro capryl triethoxyl silane 0.8-0.9, concentration are that ethanolic soln 25-30, the silane coupling agent kh5600.5-0.6 of 75wt%, polyacrylamide 0.8-1, polyvinyl alcohol ultrafine powder 2-2.5, superfine silver oxide powder 6-7, nano titanium oxide 5-6, dispersion agent NNO0.6-0.7, sepiolite powder 12-14, water are appropriate.
Described a kind of antibacterial and mouldproof pump valve proprietary powder coatings, is prepared from by following concrete steps:
(1) nano-aluminium oxide is put into the ethanolic soln that concentration is 75wt%, dispersed with stirring is even, then perfluoro capryl triethoxyl silane is added, reflux 2-2.5 hour, adds silane coupling agent kh560 after cooling, continue stirring reaction 2-3 hour, last underpressure distillation, slough the solvent in system, with the dry 60-80 minute of the temperature of 80-85 DEG C in vacuum drying oven, obtain active nano aluminium sesquioxide;
(2) nano titanium oxide is mixed with sepiolite powder, put into ball mill, with the speed ball milling 60-90 minute of 2000 revs/min, add in the water of total amount 3-5 times amount after taking-up, superfine silver oxide powder, dispersion agent NNO is added after ultrasonic disperse 20-30 minute, continue dispersion 10-20 minute, then spraying dry, obtain modified filler;
(3) hydroxy polyester resin, fluorocarbon resin, isocyanuric acid three-glycidyl ester are put into after homogenizer stirs 20-30 minute with the speed of 1000 revs/min and added active nano aluminium sesquioxide and modified filler, continue to stir discharging after 10-15 minute, compound is sent into twin screw melt extruder, continue to add all the other remaining components, melt extrude, compressing tablet, obtained fine powder through pulverizing 180 mesh sieves and get final product.
Advantage of the present invention is: the present invention adds a small amount of fluorocarbon resin Substitute For Partial hydroxy polyester resin, in the process of powder coating solidification, fluorocarbon chain section in fluorocarbon resin there occurs surface enrichment, so a small amount of fluorine just can significantly improve the hydro-oleophobicity of coating, the heat-proof water of coating, acid-proof alkaline and snappiness can be improved simultaneously; Coordinate and add through the obtained active nano aluminium sesquioxide of special process process, be easy to form chemical bonding with F-C key, make coating structure more firm, and the contact angle of coatingsurface to water sharply increases, further increase the hydrophobicity of coating, the powder coating made has anticorrosive, acid and alkali-resistance, weathering resistance, hydrophobic and lyophobic property etc. more than general powder coating excellence.
The antimicrobial components such as nano titanium oxide, superfine silver oxide powder are made modified filler by special process and are added in the formula of powder coating by the present invention, by reasonable component proportioning, powder coating is made to possess good antibacterial and mouldproof effect, simultaneously durable antibacterial effect; The paint coatings sticking power that the present invention makes is good, lastingly durable, and antibacterial and mouldproof effect is lasting simultaneously, and technique is convenient to suitability for industrialized production.
