Abstract
The invention discloses a sterilizing corrosion-resistant powder coating which consists of the following raw materials in parts by weight: 60-70 parts of E-12 epoxy resin, 10-12 parts of precipitated barium sulphate, 2-4 parts of sericite in powder, 0.4-0.6 part of epoxy ethylhexyl stearate, 5-7 parts of tetramethoxyl methyl glycoluril, 2-4 parts of flaky zinc powder, 1-2 parts of talcum powder, 1-2 parts of octyl isothiazolinone, 1-2 parts of carbon black, 2-3 parts of tungsten trioxide and 10-20 parts of composite fillers. The powder coating disclosed by the invention has a strong sterilizing corrosion-resistant effect, and can better solve the problem that a lot of bacteria in oil transpiration and water injecting pipelines of an oil field are attached to walls to breed and scaled to block pipes. The coating disclosed by the invention is strong in impact resistance of film and long in service life.
Description
Technical field
The present invention relates generally to a kind of coating, relates in particular to a kind of sterilization and anticorrosion type powder coating.
Background technology
Heat curable powder coating refers to usings thermosetting resin as filmogen, has added the solidifying agent of crosslinking reaction can form insoluble not molten quality hard coat after heating.Temperature higher this coating can be not softening as thermoplastic coating yet, and can only decompose.The resin adopting due to thermosetting powder coating(s) is the prepolymer that the polymerization degree is lower, molecular weight is lower, so the levelling property of coating is better, have ornamental preferably, and low-molecular-weight prepolymer is after solidifying, can form the macromole of cross-linked network, thereby coating have better preservative property and mechanical property.Therefore thermosetting powder coating(s) development is particularly rapid, and in order to improve the overall performance of conventional powder, by adding new compounded mix etc. to improve its performance, be necessary.
Summary of the invention
The object of the invention is exactly for a kind of sterilization and anticorrosion type powder coating is provided.
The present invention is achieved by the following technical solutions:
A type powder coating, is characterized in that what it was comprised of the raw material of following weight parts:
E-12 epoxy resin 60-70, process white 10-12, sericite in powder 2-4, octyl epoxy stearate 0.4-0.6, tetramethoxymethylglycoluril 5-7, flake zinc powder 2-4, talcum powder 1-2, octyl group isothiazolinone 1-2, carbon black 1-2, tungstic oxide 2-3, compounded mix 10-20;
Described compounded mix is comprised of the raw material of following weight parts:
Laterite 50-60, bone meal 4-6, iron ore ground-slag 10-13, wollastonite powder 5-7, tripoly phosphate sodium STPP 1-2, Dodecyl trimethyl ammonium chloride 2-3, Oil of Eucalyptus 1-2;
Above-mentioned laterite, iron ore ground-slag, wollastonite powder are mixed, at 600-800 ℃, calcine 3-4 hour, cooling discharging, add Oil of Eucalyptus, mix, obtain Preblend, tripoly phosphate sodium STPP is joined in 15-20 times of water, after stirring, add Dodecyl trimethyl ammonium chloride, rising temperature is 60-80 ℃, with above-mentioned Preblend mixed grinding, dries, cross 80-100 mesh sieve, obtain described compounded mix.
A preparation method for sterilization and anticorrosion type powder coating, is characterized in that comprising the following steps:
Above-mentioned each raw material is put into high-speed mixer and carry out pre-mixing 3-5 minute, again gained compound is put into mixing extrusion in high-speed extruder, then after compressing tablet fragmentation, then pulverize, sieve through ACM pulverising mill, obtain described sterilization and anticorrosion type powder coating.
Advantage of the present invention is:
Powder coating of the present invention has very strong sterilization and anticorrosion effect, can well solve and in oil field oil transportation, filling pipe, exist the attached wall breeding of a large amount of bacteriums in ground, dross plugging problem, the coating of the present invention shock resistance of filming strong, long service life.
