Description
Technical field
The present invention relates to a kind of polyethylene powder coating, be specifically related to a kind of magnetic polyethylene powder coating containing maleic anhydride graft activation nano-calcium carbonate 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 magnetic polyethylene powder coating containing maleic anhydride graft activation nano-calcium carbonate and preparation method thereof, the activity of the modified filler added in this invention is improved, the utilization ratio of raw material is higher, modified polyethylene powder coating use properties is better, to achieve these goals, the technical solution used in the present invention is as follows:
A kind of magnetic polyethylene powder coating containing maleic anhydride graft activation nano-calcium carbonate and preparation method thereof, it is characterized in that, this powder coating is made up of the raw material of following weight part: nano-calcium carbonate 6-10, aluminate coupling agent DL-4112-3, diethylene glycol dibenzoate 5-8, polyoxyethylene glycol 2-3, urethane thermoelastic 12-16, maleic anhydride 2-3, peroxidation diethyl isopropyl benzene 1-2, nanometer spherical ferroferric oxide magnetic powder 1-2, pigment 5-6, oxidation inhibitor 2-3, polyethylene 40-50;
Described a kind of magnetic polyethylene powder coating containing maleic anhydride graft activation nano-calcium carbonate and preparation method thereof, its preparation method is:
(1) first nano-calcium carbonate is calcined 3-4h in the oxygen atmosphere of 600-700 DEG C, be cooled to room temperature subsequently, nano calcium carbonate micro powder must be activated, again the aluminate coupling agent DL-411 of activation nano calcium carbonate micro powder and 0.6-0.8 weight part, nanometer spherical ferroferric oxide magnetic powder, maleic anhydride are mixed subsequently, be heated to 60-80 DEG C, be uniformly mixed 2-3h, obtain maleic anhydride graft activated calcium carbonate magnetic micro-powder for subsequent use;
(2) polyoxyethylene glycol is dissolved in the water of 15-18 weight part, again urethane thermoelastic is dropped in Aqueous Solutions of Polyethylene Glycol together with polyethylene, after high-speed stirring mixing 60-80min, mixture is dried removing moisture, last maleic anhydride graft activated calcium carbonate magnetic micro-powder and other remaining component adding step (1) gained again, pre-mixing 80-100min, 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: nano-calcium carbonate has been carried out oxygen activation process in advance, at its surface grafting maleic anhydride, improve bonding force and the consistency of raw material and macromolecular material greatly, the nanometer spherical ferroferric oxide magnetic powder of doping imparts the magnetic of homogenize material, obtained polyethylene powder coating shows good mobility and tack, strength of coating after application and toughness improve, and smooth surface is careful, Heat-resistant stable, there is certain magnetic, product environment-friendly high-efficiency, painting effect is excellent.
