The paint is prepared form the following steps: dissolving polyvinyl butyral in ethanol with stirring to obtain a 5-25wt% polyvinyl butyral solution; adding auxiliaries being 5-28wt% of the polyvinyl butyral into the solution and stirring for 50-80 min; adding corrosion inhibitor being 2-8wt% of the polyvinyl butyral into the prepared solution and stirring to complete dissolve; adding molybdate or iodide being 2-6wt% of the polyvinyl butyral into the prepared solution with stirring and stirring for 50-80 min. The environment-friendly paint of the invention can be applied to non-ferrous metal surface treatment, has good protective and anticorrosive effects and can keep original metal luster; a surface drying speed is fast with a time of 13-18 min; the coating has flattening and light appearance, good adhesion, high hardness, good salt spray resistance and antistatic effect.
Description
Technical field
The invention belongs to the protective system technical field, be specifically related to a kind of protective system of anti-static and preparation method thereof.
Background technology
Anti-corrosion of metal corrosion material at present commonly used mostly contains benzene series thing such as benzene, toluene, chloroform etc., in construction and use, has formed environment and human body are caused bigger harm.Polyvinyl butyral acetal has the transparency of height; Good photostabilization, water tolerance, film-forming properties and shock resistance; And nontoxic, do not have smell, non-corrosiveness; All have good adhesion property in glass, synthetic glass, metal, timber, pottery, leather, fiber and other material especially, can be used as coating, printing ink, tackiness agent etc.But the coating composition of being processed by polyvinyl butyral acetal is complicated, only just has a better preservative effect in that coat-thickness is thicker, and coating has color simultaneously, is not suitable for the requirement of colourless transparent coating material; And, existing protective system many with xylenes as mixed solvent, toxicity is big, and is bigger to environment and human harm, do not meet environmental requirement; Also having research that the Corrosion Protection of metal is mainly contained zinc powder provides, because the restriction of zinc particle size, coat-thickness is thicker, is not suitable for the requirement of shallow layer.Bring also simultaneously that construction is inconvenient, waste is big, shortcoming such as inhomogeneous during brushing.
Along with the growing interest of people, demand the development of new environment protective antiseptic protection material urgently to environment and health.Mostly adopt the thick film processing in the market, coating will even reach more than 100 microns for the 30-50 micron, and is scarcely out of swaddling-clothes for the research and development of the very thin about anticorrosive below 10 microns of coating.
Summary of the invention
The objective of the invention is provides a kind of protective system of anti-static and preparation method thereof to above-mentioned weak point.The thinner that this coating uses in construction and use to environment and body harmless; Owing to add inhibiter and compound system, the antiseptic property under the very thin condition of coating is just very excellent, is particularly useful for the anticorrosion protection of metallic surface under requirement coating very thin (as less than the 5 μ) condition; This coating water white transparency can keep the gloss of metal itself.This dope viscosity can be regulated, and construction easily can be selected technologies such as brushing or spraying.
What this explained hereafter was used is enamel reaction still equipment, rather than general carbon steel or stainless steel cauldron, and the main effect of its reaction is to make starting material not direct contacting metal in entire reaction, can avoid corrosion on Equipment has also been guaranteed the purity of quality product.
The object of the invention is specifically realized in the following manner:
A kind of protective system of anti-static is characterized in that this coating is prepared by following steps:
A, under agitation polyvinyl butyral acetal is dissolved in the ethanol, obtains the polyvinyl butyral acetal solution of 5～25 weight %;
B, the auxiliary agent that will be equivalent to polyvinyl butyral acetal 5～28 weight % add in the above-mentioned solution, stir 50～80 minutes, and described auxiliary agent is coupling agent KH550 and flow agent butanols;
C, get the inhibiter that is equivalent to polyvinyl butyral acetal weight 2～8% and add in the b prepared solution, be stirred to dissolving fully; Described inhibiter comprises 1 or 2 kind of mixing in phenylpropyl alcohol triazole, phenylpropyl alcohol triazole derivative, 2-hydroxyl phenylpropyl alcohol thiazole derivative, benzimidazole, benzimidazole derivative, benzene third oxazole, the benzene third oxazole derivative;
D, stir the molybdate that will be equivalent to polyvinyl butyral acetal weight 2～6% down or iodide and add in the c prepared solution and stirred 50～80 minutes; Described iodide are sodium iodide or potassiumiodide.Described molybdate can be Sodium orthomolybdate or potassium molybdate.
The preparation method of the above-mentioned protective system of anti-static may further comprise the steps:
A, under agitation polyvinyl butyral acetal is dissolved in the ethanol, obtains the polyvinyl butyral acetal solution of 5～25 weight %;
B, the auxiliary agent that will be equivalent to polyvinyl butyral acetal 5～28 weight % add in the above-mentioned solution, stir 50～80 minutes, and described auxiliary agent is coupling agent KH550 and flow agent butanols;
C, get the inhibiter that is equivalent to polyvinyl butyral acetal weight 2～8% and add in the b prepared solution, be stirred to dissolving fully; Described inhibiter comprises 1 or 2 kind of mixing in phenylpropyl alcohol triazole, phenylpropyl alcohol triazole derivative, this sick thiazole derivative of 2-hydroxyl, benzimidazole, benzimidazole derivative, Ben Bing oxazole, the Ben Bing oxazole derivative;
D, stir the molybdate that will be equivalent to polyvinyl butyral acetal weight 2～6% down or iodide and add in the c prepared solution and stirred 50～80 minutes; Described iodide are sodium iodide or potassiumiodide.
Polyvinyl butyral acetal according to the invention comprises the product of different process, different molecular weight.The sustained release dosage that uses uses for one or more heterogeneous ring compounds mix.Heterogeneous ring compound mainly comprises: phenylpropyl alcohol triazole and derivative, and 2-sulfydryl phenylpropyl alcohol thiazole and derivative, benzimidazole and derivative, Ben Bing oxazole and derivative etc. add molybdate, halogenide etc. again.Inhibiter can be formed compound system with inorganic salt, further improves Corrosion Protection and also can improve the abrasion property ability simultaneously.Various auxiliary agents be can add and the bonding force and the execution of coating performance of coating and metallic surface improved; Also can add the coating that various fillers obtain different colours and viscosity.Catalyzer is selected quaternary ammonium, boride etc. for use.
With prior art beneficial effect more of the present invention: coated material of the present invention the construction, deposit and use after do not discharge the volatile organic matter that country prohibites, be environment-friendly type coating; This application of paints has the favorable protection preservative effect and can keep the metalluster of metal itself after non-ferrous metal surface treatments such as copper and alloy, aluminum magnesium alloy; Surface drying speed is fast, and making an appointment is 13～18 minutes, the appearance of coat smooth, and sticking power is good, and hardness is high, and salt spray resistance is good, and has anti-static effect.
