Description
Technical field
The present invention relates to the volatile rust prevention field of plastic products, refer to a kind of anti-rust master batch and preparation and application method that is suitable for multiple metallic surface and coated layer thereof particularly.
Background technology
The volatile rust prevention plastics are to be a gas-like phase rush-resisting material of vapor phase corrosion inhibitor agent carrier with the macromolecule resin; Its main form comprises products such as gas-phase antirust plastic film, volatile rust prevention adhesive tape, volatile rust prevention plastic packaging bag, volatile rust prevention shrink film; Be widely used in controlling gold, automobile, electronic apparatus; Mechanical component, fields such as military project.To be the vapour-phase inhibitor that contains with plastics to the rust-proof effect of metal produce the synergistic results of shielding effect to the active adsorption and the plastics of metallic surface to the volatile rust prevention plastics to ambient atmosphere.
Control golden industry its coated layer except that metal species is various in recent years and change irregularly infinitely especially, only with regard to a kind of galvanized sheet: substrate has zinc zinc alloy, zinc-iron alloy, aluminium zinc, aluminium-zinc alloy; Have purifying, have purifying, that sexavalence network purifying is arranged, trivalent network purifying is arranged, the environmental protection purifying; Oiled is arranged, oiled is arranged not, not oiled of purifying is arranged, also have oiling not purifying etc. stack combinations get up up to two, 30 kind.And existing volatile rust prevention plastics in general, and function is comparatively single, and only to part underlying metals such as steel or copper, or part coated layer metal has rust-proof effect, and the rust-preventive agent volatilization slowly, and the vapor phase corrosion inhibitor ability is scarcely qualified.Also there are not a kind of volatile rust prevention plastics can be applicable to underlying metal and coated layer metal simultaneously in the prior art.Therefore, when metal being done the volatile rust prevention processing, to adopt different volatile rust prevention plastics, increase operator's workload, and adopted multiple volatile rust prevention plastics can produce waste unavoidably to different metallic.
Also there is defective in the making method of the volatile rust prevention plastics that generally adopt in the prior art in addition: a kind of method is extruding pelletization after adopting 4 ~ 8% rust-preventive agent and 92 ~ 96% carrier plastics mixing blown film or pouring film again.But, because strong anti-embroidery agent and the nonpolar plastics of utmost point domestic animal are not easy to be combined in above-mentioned mixing process, thereby cause rust-preventive agent in the carrier plastics, to disperse inhomogeneous and influence rust-proof effect, analyse white serious phenomenon.Another kind method is for being base material with the plastic film, is coated on the plastic film after rust-preventive agent and the caking agent mixing, and this method not only energy consumption is big, and complex procedures more can not cleaner production, and equally easily because of mixing the inhomogeneous rust-proof effect that influences.
Summary of the invention
The objective of the invention is to overcome the existing functional incomplete defective of volatile rust prevention plastics, a kind of anti-rust master batch and preparation and application that is suitable for multiple metallic surface and coated layer thereof is provided.
Be the realization above-mentioned purpose, the anti-rust master batch that is suitable for multiple metallic surface and coated layer thereof that the present invention designed, wherein the weight accounting of each component is 40 ~ 45% rust-preventive agent, 40 ~ 45% carrier plastics and 10 ~ 20% auxiliary agents; Said rust-preventive agent is by acetate imidazoles, 1H-1, and 2,4-triazole, Sodium orthomolybdate are by weight being 1 ~ 1.2: 0.9 ~ 1.3: 2.8 ~ 3.5 mixed forms; Said auxiliary agent by boric acid ester, stearic acid amide, water-ground limestone by weight being 2.9 ~ 3.2: 0.8 ~ 1.1: 5.7 ~ 6.3 mixed forms.
Preferably, said rust-preventive agent is by acetate imidazoles, 1H-1, and 2,4-triazole, Sodium orthomolybdate form by weight the mixed that is 1: 1: 3; Said auxiliary agent is formed by weight the mixed that is 3: 1: 6 by boric acid ester, stearic acid amide, water-ground limestone.Need to prove that water-ground limestone can be buied by commercially available.
Said carrier plastics are that density is at 0.90 ~ 0.96g/cm
3Vilaterm, be preferably a kind of in new LDPE (film grade), the LLDPE or both mixtures, more preferably high pressure low density polyethylene (LDPE) 1C7A.
Said boric acid ester is preferably boric acid ester coupler PCR-100.
The particle diameter of said rust-preventive agent is 900 ~ 2500 orders, is preferably 900 ~ 1100 orders.
The existing coupled action of boric acid ester coupler PCR-100 that is adopted among the present invention, lubricated and dissemination again and have collaborative effectiveness between the rust-preventive agent, strengthen antirust effect.The rust-preventive agent that is adopted is to be to be main mixed type rust-preventive agent about 1000 orders, with the heterogeneous ring compound through powder particle diameter: acetate imidazoles, 1H-1,2, the mixture of 4-triazole, Sodium orthomolybdate.The mixture of this rust-preventive agent both had certain polarity can penetrate the carrier plastics evaporate into or be deposited to pack the metallic surface, form to intercept extraneous corrosive deposit protective membrane, reach rust-proof effect, simultaneously also not can because its polarity cross strong and incompatible with the carrier plastics, cause analysing white phenomenon and take place.
A kind ofly prepare the above-mentioned method that is suitable for the anti-rust master batch of multiple metallic surface and coated layer thereof, comprise the steps:
1) by said weight proportion with rust-preventive agent, carrier plastics and auxiliary agent mixed at high speed 4 ~ 15 minutes, obtain compound;
2) earlier to the gained compound mediate, melting treatment, under 150 ~ 180 ℃ temperature condition, extrude then through mixing, plasticizing, make and be suitable for the anti-rust master batch that multiple metallic surface and coated layer thereof are protected.
A kind of above-mentioned application method that is suitable for the anti-rust master batch of multiple metallic surface and coated layer thereof may further comprise the steps:
(1) earlier said anti-rust master batch is added in the feed particles of thermoplastics according to 1: 25 ~ 50 ratio, make the antirust plastic composite grain;
(2) again with gained antirust plastic composite grain through blown film or drench film, be processed into the gas-phase antirusting film wrapping material, the metallic surface that is used to wrap up various naked metallic surfaces or has coated layer.
Beneficial effect of the present invention: the anti-rust master batch that is suitable for multiple metallic surface and coated layer thereof that is provided, overcome the defective that existing gas-phase rustproof packaging material can not be applicable to multiple metal and its surfaces coated coating, can be to underlying metal such as steel; Copper, aluminium, metals such as magnesium rise outside the rust inhibition; Also can adapt to such as zinc-plated; Zinc-plated, oriented silicon steel, the rustproof packing of non orientating silicon steel etc.In addition, the consumption of anti-rust master batch is few among the present invention, and price is low, and its preparation method has been simplified the anti-wrapping material production technique of embroidering of gas phase, and is simple to operate, is uniformly dispersed high-efficiency environment friendly.
