Technical field
The present invention relates to a kind of polyethylene powder coating, be specifically related to a kind of waterproof type polyethylene powder coating containing nanometer silver grafting oildag 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, prepare a kind of waterproof type polyethylene powder coating containing nanometer silver grafting oildag and preparation method thereof, the material modified activity of wherein adding is improved, and modification efficiency is higher, to achieve these goals, the technical solution used in the present invention is as follows:
A kind of waterproof type polyethylene powder coating containing nanometer silver grafting oildag and preparation method thereof, it is characterized in that, this powder coating is made up of the raw material of following weight part: polyether-ether-ketone micro mist 3-5, nano silver colloidal sol 1-3, oildag powder 4-6, trimethyl silicane sodium alkoxide 1-1.5, potassium permanganate 0.4-0.6, pigment 5-8, acefal homopolymer 12-15, polyoxyethylene 2-3, silane resin acceptor kh-550 2-3, polyethylene 42-48, oxidation inhibitor 2-3, glycidyl methacrylate 4-6;
Described a kind of waterproof type polyethylene powder coating containing nanometer silver grafting oildag and preparation method thereof, its preparation method is:
(1) first oildag powder is calcined 2-3h in the nitrogen atmosphere of 700-800 DEG C, pulverize after being cooled to room temperature subsequently, cross 400-600 mesh sieve, obtain pre-activate oildag micro mist, pre-activate oildag micro mist to be dropped into the concentration be mixed with by potassium permanganate be subsequently the pH value of 35-50g/L is again in the acidic aqueous solution of 5-6, 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, nano silver colloidal sol, be heated to 50-60 DEG C, high-speed stirring mixing 2-2.5h, obtain nanometer silver grafting and activating oildag micro mist for subsequent use,
(2) polyoxyethylene is dissolved in the water of 15-18 weight part, again polyether-ether-ketone micro mist, acefal homopolymer are dropped in polyoxyethylene aqueous solution together with polyethylene, after high-speed stirring mixing 50-60min, mixture is dried removing moisture, last nanometer silver grafting and activating oildag micro mist and other remaining component adding step (1) gained again, pre-mixing 2-3h, 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: oildag powder has been carried out activation treatment in advance, and at its surface grafting clad nano silver composition, oildag powder compounded mix after such process and the bonding force of macromolecular material and consistency better, modified effect is better, powder coating prepared by the present invention shows good mobility and tack, coating mechanical property is good, surface compact is antibacterial, not easily degenerate variable color, water resistance is excellent, and the simple environmental protection of preparation method, production cost is controlled, has application value.
