Description
Technical field
The coil steel coating composition and a kind of preparation method who executes the coil steel materials of covering this coil steel coating composition that the present invention relates to a kind of mixed solvent and contain this mixed solvent.
Background technology
Coil steel coating is a kind of speciality coating that is applicable to metal coil coating process.Requirement and the increasingly extensive application of coil due to coating process, make the requirement of coil steel coating more and more higher.For example, coating process is to use roller coating machine to carry out continuous application to band, and this just requires coil steel coating at high temperature will be dried rapidly; Meanwhile, in drying process, steel billet temperature is up to 220-260 ℃, and in by roaster, ambient temperature is more up to 400 degree, and therefore, it is of crucial importance that the thermotolerance of coil steel coating just becomes; In addition, when coil steel coating is used in home appliances surface, owing to often contacting with household chemical product or sanitising agent, also must consider its chemical resistance, hypotoxicity etc.In addition, coil steel coating also will possess some fundamental propertys of coating simultaneously, as glossiness, and levelling property and sticking power etc.
But in prior art, various compositions as coil steel coating are difficult to meet above-mentioned various requirement simultaneously, this is relevant with the solvent using in coil steel coating, in coil steel coating, conventional solvent has a variety ofly, and specifiable have esters solvents such as ethyl acetate, N-BUTYL ACETATE, 2-butyl acetate, nylon acid dimethyl ester mixture (DBE), propylene-glycol ether acetate, Solactol ester; The ether solvent such as glycol ether, propylene glycol; The ketones solvent of acetone, methyl ethyl ketone, methyl iso-butyl ketone (MIBK), 2-heptanone, pimelinketone, isophorone class (Japanese kokai publication sho 63-69563 communique).In these solvents, although butylacetate has good dissolution rate, but volatility is too high, and the dissolution rate of propylene glycol monomethyl ether acetate and Solactol ester is slower, there is inexpungible shortcoming, be difficult to independent use, although ethylene glycol monomethyl ether acetate has good dissolution rate, suspect to have and bring out the toxicity of Infertility and ban use of.
In order to make up the shortcoming of so single composition, developed mixed solvent, composition (the United States Patent (USP) the 4th of the solvent compositions (Japanese kokai publication hei 7-146562 communique) for example being formed by propylene glycol alkyl ether and 3-alkoxypropan acid alkyl ester class, the solvent being formed by propylene glycol alkyl ether acetic acid ester and propylene glycol alkyl ether, 983, No. 490 communiques).When above-mentioned composition causes operator's unplessantness displeasure and dislike due to stench, exist due to toxic and damage healthy misgivings.Therefore, mixed solvent is in the past in solvability, volatility, the aspect existing problems such as toxic; Nylon acid dimethyl ester mixture (DBE) is for producing hexanodioic acid by product, and the component of mixture proportional difference of each manufacturer production is larger, and solvent nature is difficult to stable and large usage quantity, also only limits to use in some field (CN 101402814A); Aromatic solvent naphtha kind solvent is endangered the staff of construction, finishing etc., kinsfolk's health, environment has also been caused to pollution simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of mixed solvent that can overcome above-mentioned defect and the coil steel coating composition that contains this mixed solvent and use this coil steel coating composition to prepare the method for coil steel materials.
The invention provides a kind of mixed solvent, it is characterized in that, described solvent contains the secondary monooctyl ester of acetic acid and cosolvent, described cosolvent be can with the organic solvent of the secondary monooctyl ester complete miscibility of acetic acid, wherein, the weight ratio of the acetic acid monooctyl ester second month in a season and cosolvent is 1: 0.1-30.
The invention provides a kind of coil steel coating composition, it is characterized in that, the total amount of composition of take is benchmark, and described composition contains:
(1) the above-mentioned mixed solvent of 1-50 % by weight;
(2) matrix resin of 10-70 % by weight, described matrix resin is at least one in urethane resin, polyacrylic resin, vibrin, Synolac, epoxy resin;
(3) titanium dioxide of 1-40 % by weight;
(4) aerosil of 0.1-1 % by weight.
The invention provides a kind of preparation method of coil steel materials, the method is included in coil substrate surface and executes and cover coating composition and this coating composition is solidified, and it is characterized in that, described coating composition is above-mentioned coil steel coating composition.
The coil steel coating composition that uses mixed solvent provided by the invention to obtain as solvent is that the mobile property of coil steel coating composition provided by the invention is good, and solid content is high, and stability is strong, without benzene toxicity, the paint film forming is Clear & Transparent, and the levelling property having had, can avoid coiled steel plate interface to trail.
Adopt the coil steel materials of preparation method's acquisition of coil steel materials provided by the invention to have an even surface, glossiness is high, and the tack of coating is good.
Embodiment
The invention provides a kind of mixed solvent, it is characterized in that, described solvent contains the secondary monooctyl ester of acetic acid and cosolvent, described cosolvent be can with the organic solvent of the secondary monooctyl ester complete miscibility of acetic acid, wherein, the weight ratio of the acetic acid monooctyl ester second month in a season and cosolvent is 1: 0.1-30.
The coil steel coating composition that uses mixed solvent provided by the invention to obtain as solvent is that the mobile property of coil steel coating composition provided by the invention is good, solid content is high, stability is strong, without benzene toxicity, with the composite coil steel coating of said composition, the paint film forming is Clear & Transparent, and the levelling property having had, can avoid coiled steel plate interface to trail.This may be because for the solvent in solvent-borne type coil steel coating, determine that the important factor of its performance has intermiscibility, viscosity and volatility.
Intermiscibility refers to that used solvent need to all have good compatibility to various kinds of resin, thereby plays the effect of thinner, and the paint film of spraying just can be Clear & Transparent like this.
Viscosity be solvent to resin dissolves ability important parameter, different solvents is because of the performance difference of dissolving resin, the viscosity of gained solution also has larger difference.When utilizing nozzle ejection, if viscosity is too high, spraying pressure is uprised, thereby increased the usage quantity of unnecessary solvent, increased cost.On the other hand, if viscosity is too low, on the interface that is sprayed on coiled steel plate that resin can not be concentrated.
Volatility relates to whether volatilization and do not remain in the important factor of substrate surface rapidly of solvent, when volatility is too low, not only cause solvent non-volatile and residual, at coiled steel plate interface, derive conditions of streaking, and in subsequent handling, also there will be problems such as making the reduction of manufacturing procedure production efficiency.On the other hand, when volatility is too high, coiled steel plate is cooling rapidly, and the resin of spraying can not completely dissolve and adhere to, thereby easily causes the defect that paint film blast hole and overbaking cause.
The secondary monooctyl ester of acetic acid (2-octyl acetate is called for short 2OA), molecular formula is C
