The prepared polyethylene powder paint has favorable flowability and adhesiveness. The coating has the advantages of higher strength, higher toughness, smooth surface, low tendency to cracking and shedding, high temperature resistance, oxidation resistance, controllable production cost and favorable application effect.
Description
Technical field
The present invention relates to a kind of polyethylene powder coating, be specifically related to a kind of containing carbon nano fiber grafting and activating bentonite toughening type polyethylene powder coating 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 carbon nano fiber grafting and activating bentonite toughening type polyethylene powder coating and preparation method thereof, and 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 containing carbon nano fiber grafting and activating bentonite toughening type polyethylene powder coating and preparation method thereof, it is characterized in that, this powder coating is made up of the raw material of following weight part: 400-600 order organobentonite 4-8, carboxymethyl cellulose 1-2, carbon nano fiber 0.4-0.5, ester gum 3-5, silane resin acceptor kh-550 2-3, pigment 5-8, polyethylene 42-50, potassium permanganate 0.4-0.5, acrylonitrile-butadiene-styrene resin 10-14, acrylate flow agent 1-2, oxidation inhibitor 2-3;
Described one is containing carbon nano fiber grafting and activating bentonite toughening type polyethylene powder coating and preparation method thereof, and its preparation method is:
(1) first organobentonite micro mist being dropped into the concentration be mixed with by potassium permanganate is 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, carbon nano fiber, be heated to 60-80 DEG C, high-speed stirring mixing 1.5-2h, obtains carbon nano fiber grafting and activating organobentonite micro mist for subsequent use;
(2) carboxymethyl cellulose is dissolved in the water of 10-12 weight part, drop into together with polyethylene in carboxymethyl cellulose aqueous solution after again polyacrylonitrile fibre being ground into powdery, after high-speed stirring mixing 40-60min, mixture is dried removing moisture, last carbon nano fiber grafting and activating wilkinite micro mist 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: organobentonite has been carried out activation treatment in advance, at its surface grafting carbon nano fiber, improve bonding force and the consistency of micro-dimension filler and macromolecular material greatly, obtained polyethylene powder coating modified effect promotes further, raw material availability greatly improves, powder coating prepared by the present invention shows good mobility and tack, the intensity of coating and toughness improve, and it is smooth, not easily be full of cracks comes off, fire-resistant oxidation resistant, production cost is controlled, and painting effect is excellent.
