Abstract
The present invention belongs to the field of corrosion-proof decorative paint. The paint is compounded from silver-aluminium powder, polystyrene foam plastic, a modifying agent and a solvent, wherein the modifying agent adopts a thermoplastic elastomer SBS and carbon-nine petroleum resin; the solvent adopts xylene, aromatic solvent oil or the mixture of the xylene and the aromatic solvent oil; the aromatic solvent oil comprises carbon-nine aromatic solvent oil and carbon-ten aromatic solvent oil. The paresnet invention has the advantages of simple technology, stable performance of silver-aluminium powder paint, high water resistance, high wear resistance, high low temperature resistance and high luminance of coatings, and the drying speed of the paint can be regulated according to occasions and changes of weather.
Description
The invention belongs to anticorrosion and the decorative paint field, be the method for a kind of silver-colored aluminium powder paint and preparation thereof.
At present, being used for anti-corrosion of metal and general ornamental silver-colored aluminium powder paint, generally is to concoct with varnish on the market with silver-colored aluminium powder to form, and as alkyd paint, perchloropolyvinyl paint, all kinds of enamel paint etc., but there are many defectives in they, as: silver-colored aluminium powder and varnish can only separately be packed; Silver aluminium powder and varnish proportioning are difficult for grasping during use; Silver aluminium powder and varnish are mixed the back as not using up the same day, and easily blackening is rotten, the easy skinning of product silver aluminium powder paint; Heat resistance is poor, and rate of drying can't be according to needs free adjustment of use occasion and weather etc.
It is low that polystyrene has a water-intake rate, only be 0.02%, transparency reaches more than 90%, and has high-frequency insulation, wear-resisting, acidproof, water-fast, anti-salt, advantages such as weather resistance is good, can make the coating lacquer of better performances according to this, yet in itself, dry back is to the sticking power extreme difference of metal objects, resistance to low temperature is bad, thereby has restricted the performance of its premium properties, and prior art utilizes waste old polystyrene foamed plastic as film forming matter, make lacquer by the modification processing, mainly by two kinds of approach: (1) is dissolved in solvent to waste and old polystyrol, adds properties-correcting agent then and mixes, and carries out physically modified.Properties-correcting agent is mainly natural rubber, chloroprene rubber, styrene-butadiene rubber(SBR), resol, Gum Rosin, aminoresin, Synolac, ester plasticizer isopolarity material, yet they all have a bigger common defects, be exactly that layering appears in interior properties-correcting agent of short period of time and polystyrene resin, influenced the quality (separation time is many not to be waited) of lacquer between 20-80 hour; (2) waste old polystyrene foamed plastic is dissolved in solvent, under the condition of certain temperature and initiator, introduces active gene, as-the NCO base, carbonyl etc.Its main drawback be cost than higher, complex process, be difficult for to grasp.Can make silver-colored aluminium powder paint by these two kinds of approach, because Synergist S-421 95, main form with packing is released, and limited in aspect modifications such as toughness, hardness, fragility.In addition, the lacquer majority made from waste and old polystyrol all is a quick-drying, and is still better in microthermal climate because the solvent majority is based on toluene, dimethylbenzene, chloroform, 120# gasoline, ethyl acetate etc., and hot weather is serious, the levelling property of influence lacquer.The adding 200# gasoline that has reduces rate of drying, yet but this has promoted the demixing phenomenon (200# industrial naptha p-poly-phenyl ethenoid resin is poorly soluble) between properties-correcting agent and the polystyrene resin.
The objective of the invention is to overcome above-mentioned shortcoming, a kind of novel silver-colored aluminium powder paint and preparation method thereof is provided, described silver-colored aluminium powder paint utilizes polystyrene as filmogen, it is carried out reasonable modification, make it to have stable performance, superior in quality: good toughness, advantage such as wear-resisting, the preparation method is simple and easy to do.
The present invention also aims to select for use rational solvent, the rate of drying that makes silver-colored aluminium powder paint is with use occasion and different weather free adjustment.
The objective of the invention is to realize in the following way:
The silver aluminium powder paint, comprise silver-colored aluminium powder, polystyrene foamed plastics, change agent, solvent, be characterised in that properties-correcting agent is thermoplastic elastomer SBS's (polymkeric substance of styrene-butadiene-styrene) and C 9 petroleum resin, by weight, the content of each moiety is, silver aluminium powder 10-14%, polystyrene foamed plastics 5-8%, SBS1-2%, C 9 petroleum resin 8-17%, solvent 63-70%, described solvent is dimethylbenzene, aromatic solvent naphtha or the mixture of the two, and aromatic solvent naphtha comprises c9 aromatic solvent oil and C10 aromartic solvent oil.
The method for preparing silver-colored aluminium powder paint adds desilver aluminium powder other component in addition in solvent, stirred 10-12 hour, adds silver-colored aluminium powder then, stirs to get final product in 1-2 hour.
The thermoplastic elastomer SBS has been the effect of solid plasticizer, and it has improved the toughness and the resistance to low temperature of this product, yet increasing of its amount directly influences weathering resistance, the hardness of product again, causes the consequence of the standard code that does not meet silver-colored aluminium powder paint.C 9 petroleum resin is a kind of tackifying resin that is widely used in painting industry, and it has the effect of three aspect in the present invention, the one, lift from the sticking power of product to object; The 2nd, utilize it with the proximity of polystyrene molecule and good mutual solubility; Improve modifying function; The 3rd, acidity is very low, and is low to silver-colored aluminium powder corrodibility.C 9 petroleum resin promptly as tackifier again as properties-correcting agent, SBS and carbon nine oil resins are the reasonable properties-correcting agent of polystyrene, thereby improved the quality of silver-colored aluminium powder paint, select for use dimethylbenzene and carbon nine or C10 aromartic solvent oil as mixed solvent, make silver-colored aluminium powder paint under varying environment, good levelling property can be regulated and have to rate of drying, guaranteeing levelling property, under the prerequisite of paint impregnability, low temperature season dimethylbenzene amount improves relatively, also can directly promote fast doing with dimethylbenzene, high temperature season carbon nine or C10 aromartic solvent oil mass increase relatively, also can directly use, reduce rate of drying, so the rate of drying of product promptly quick-drying (as surface drying in 10 minutes), also (a few hours surface drying) of slow curing.
The present invention's silver aluminium powder paint quality and technical index is as follows;
1, paint film color and outward appearance: paint film is smooth, smooth, bright silver;
2, viscosity (rotary viscosity): 300-400 centipoise;
3, fineness (micron)≤40;
4, opacifying power (gram/square metre):＜100 grams;
5, time of drying (normal temperature): surface drying 10-300 minute
Did solid work 24 hours;
6, water tolerance: product is dipped in the water, places 5 days no changes;
7, alkali resistance: under the room temperature, soak 48 hours no changes in the saturated aqua calcis;
8, snappiness (millimeter): 1
9, sticking power (cross-hatching): 100%.
Advantage of the present invention:
1, technology is simple;
2, silver-colored aluminium powder paint is stored for a long time never degenerates, resistance to low temperature good (20-100 ℃), and water and wear resistance is better, and enamelled coating brightness is higher and stable, has overcome the defect that existing silver-colored aluminium powder paint is easily stung the end;
3, rate of drying can be regulated fast doing or slow curing as required;
4, cost is low.
