Description
Technical field
The present invention relates to a kind of polyethylene powder coating, be specifically related to a kind of containing diatomaceous high preservative property polyethylene powder coating of graphene oxide grafting and activating and preparation method thereof.
Background technology
Polyethylene powder coating occupies very large proportion in existing thermoplastic powder coating, its advantage main manifestations is that raw material is cheap, resistance to chemical attack, good electrical insulating property and low-temperature stability, but its shortcoming is also obvious, during use, physical strength is poor, and film adhesive is poor, easily chaps in surface, anticorrosion and weathering resistance also has much room for improvement, expanding the use range of polyethylene powder coating to continue, improving its competitive power in like product, improving its use properties imperative.
The poly performance approach of current improvement is mainly divided into physically modified and chemical modification two kinds of methods, although these method of modifying are all widely used at present, also positive effect has been played at the aspect of performance improving polyethylene powder coating, but, no matter be modified filler, the macromolecular material of blending and modifying or grafting, cross-linking monomer, consistency and the binding activities of they and polyethylene base-material are particularly important, are also to ensure modification efficiency, improve the basic of raw material availability; Therefore improve the performance that these tradition are material modified, simultaneously in conjunction with the use of novel material, the polyethylene powder coating that performance is more excellent can be developed.
Summary of the invention
The object of the invention is to, preparation is a kind of containing diatomaceous high preservative property polyethylene powder coating of graphene oxide grafting and activating and preparation method thereof, the activeconstituents wherein added improves the consistency with polythene material, modified effect is better, to achieve these goals, the technical solution used in the present invention is as follows:
A kind of containing diatomaceous high preservative property polyethylene powder coating of graphene oxide grafting and activating and preparation method thereof, it is characterized in that, this powder coating is made up of the raw material of following weight part: diatomite 5-8, polyacrylonitrile fibre 10-15, potassium permanganate 0.4-0.5, polyvinyl alcohol 1-2, graphene oxide 1-1.5, glycidyl methacrylate 5-8, silane resin acceptor kh-550 2-4, ammonium polyphosphate 1-3, oxidation inhibitor 2-3, pigment 6-10, polyethylene 48-55;
Described one is containing diatomaceous high preservative property polyethylene powder coating of graphene oxide grafting and activating and preparation method thereof, and its preparation method is:
(1) first diatomite is calcined 1.5-2h in the nitrogen atmosphere of 430-460 DEG C, pulverize after being cooled to room temperature subsequently as 400-600 order micro mist, obtain pre-activate kieselguhr micropowder, again pre-activate kieselguhr micropowder being dropped into the concentration be mixed with by potassium permanganate is subsequently in the aqueous solution of 30-50g/L, soak 40-60min, subsequent filtration, after filtrate washes 3-5 time with water, add the silane resin acceptor kh-550 of 0.5-0.8 weight part, graphene oxide, be heated to 60-80 DEG C, high-speed stirring mixing 1.5-2h, obtains graphene oxide grafting and activating kieselguhr micropowder for subsequent use;
(2) polyvinyl alcohol is dissolved in the water of 10-12 weight part, drop into together with polyethylene in polyvinyl alcohol water solution after again polyacrylonitrile fibre being ground into powdery, after high-speed stirring mixing 40-60min, mixture is dried removing moisture, last graphene oxide grafting and activating diatomite and other remaining component adding step (1) gained again, pre-mixing 1-2h, drop into melting mixing extruding pelletization in twin screw extruder subsequently, pellet is sent into after fine powder worn into by pulverizing mill and is entered powder shifter classification again, to obtain final product.
The advantage of modified poly ethylene powder coating prepared by the present invention is: diatomaceous earth filler has been carried out activation treatment, simultaneously at its surface grafting graphene oxide, improve the consistency of micro-dimension filler and macromolecular material greatly, obtained polyethylene powder coating modified effect is better, raw material availability greatly improves, powder coating prepared by the present invention shows good mobility and tack, coatingsurface flat smooth, coating is tough and tensile, not easily chap, resistance to chemical attack, production cost is low, and protection effect is excellent.
