Abstract
The invention discloses wear-resistant valve antifouling powdery paint. High-hydroxyl polyester resin and hydroxy acrylic resin are taken as main film-forming substances, HDI trimer is taken as a curing agent, the product high/low-temperature resistance is improved after modified polyvinylidene fluoride is added, and other effective additives are added, are good in intermiscibility after being modified, are capable of rapidly floating on a paint film surface, and are fixedly attached to the paint film surface through hydroxyl and -NCO, so that pollutants are difficult to attach to the paint film surface, and therefore the paint film possesses durable antifouling performance, and the prepared product possesses characteristics of good wear resistance, good waterproof performance, capability of resisting water invasion and good weatherability besides effective antifouling performance.
Description
Technical field
The present invention relates to paint field, be specifically related to antifouling powder coating of a kind of wear-resistant type valve and preparation method thereof.
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.Valve housing painting can be widely used in load onto.Because valve body 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 valve to be restricted in special dimension application such as food, biology, pharmacy, chemical industry, space flight and electronics.Thus research and develop multi-functional weather-proof, high-low temperature resistant, waterproof antiwear, anlistatig self-cleaning anti-pollution powder coating, possess skills the meaning promoting to improve with industry.
Summary of the invention
Object of the present invention is just to provide antifouling powder coating of a kind of wear-resistant type valve and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
The antifouling powder coating of a kind of wear-resistant type valve, it is characterized in that, be made up of the raw material of following weight part: high hydroxy polyester resin 51-61, Hydroxylated acrylic resin 23-34, HDI tripolymer 4-6, polyvinylidene difluoride (PVDF) 11-18, nano titanium oxide 1-3, Silane coupling agent KH550 3-5, N-Methyl pyrrolidone 0.3-0.6, flyash 8-13, aluminum silicate fiber 2.1-3.5, molybdenumdisulphide 0.1-0.4, methyl methacrylate 11-14, white oil 9-13, N,N-DIMETHYLACETAMIDE 24-34.
The preparation method of the described antifouling powder coating of a kind of wear-resistant type valve, is characterized in that comprising the following steps:
(1) by methyl methacrylate, white oil stirring and evenly mixing, be warming up to 75-95 DEG C and add flyash, fully stir and condensing reflux reaction 2-4h, ultrasonic disperse is even, and spraying dry obtains modified coal ash;
(2) by nano titanium oxide in 720-830 DEG C of high-temperature calcination 30-50 minute, be cooled to room temperature ultrasonic concussion 20-40 minute, add Silane coupling agent KH550, N-Methyl pyrrolidone stirring and evenly mixing, be warming up to 60-80 DEG C, add aluminum silicate fiber extra-fine grinding 1-3 hour, dry for standby;
(3) in N,N-DIMETHYLACETAMIDE, add polyvinylidene difluoride (PVDF), after 35 DEG C of heating in water bath are dissolved to clarification, add modified coal ash ultrasonic disperse evenly, carry out electrostatic spinning, pulverize;
(4) high hydroxy polyester resin, Hydroxylated acrylic resin are put into high mixer high speed and be uniformly mixed 40-60 minute, add step (2), step (3) material and other remaining component, pre-mixing 1-2 hour, drop into melting mixing extruding pelletization in twin screw extruder, pellet is sent into pulverizing mill and is worn into fine powder discharging.
The present invention has following beneficial effect: the present invention selects high hydroxy polyester resin, Hydroxylated acrylic resin is main film forming matter, HDI tripolymer is solidifying agent, add the high and low temperature resistance that modified polyvinylidene difluoride (PVDF) improves product, also add other effective additives and in addition modified simultaneously, intermiscibility is good, coating surface can be floated to rapidly, coating surface is fixed on by hydroxyl and-NCO reaction, pollutent is made to be difficult to attach to coating surface, thus make paint film have lasting polluting proofing property energy, obtained product except effective antifouling except, also there is wear resistance good, water-repellancy Canon stops the invasion of moisture, the feature of good endurance.
