This invention relates to an inorganic zinc powder paint that exhibits excellent storage stability and corrosion resistance on metal surfaces.

高いシラノール基（３ｓｔ−ＯＨ）と亜鉛との間で化学
的に反応することに起因する。Conventional technology In the past, inorganic zinc powder paints containing a hydrolyzed solution of alkyl silicate such as ethyl silicate and zinc dust as main ingredients have been widely used to protect the surfaces of metals such as iron and copper. Furthermore, the film formed from the paint has excellent corrosion resistance and heat resistance, and this is well known. However, the above-mentioned paint is of a type in which the alkyl silicate hydrolyzate and the zinc powder are stored separately in a one-liquid, one-powder state, and mixed together before painting. Depending on the degree of hydrolysis of the silicate, the problem is that it gels within several tens of hours to several hours, making it impossible to paint. This is economically disadvantageous because the usable time is very short, and the paint once mixed must be used up at the same time, and cannot be handled for general purposes like ordinary organic paints. Yes, and its uses are also limited. The gelation of this mixture is caused by a chemical reaction between the highly reactive silanol group (3st-OH) of the alkyl silicate hydrolyzate and zinc.

発揮できない。However, as a method for solving the above-mentioned problems, it is conceivable to use an alkyl silicate having no silanol group in its structure instead of the hydrolyzed solution of the alkyl silicate in the above-mentioned mixture. However, paints using this material, such as alkyl silicate (e.g. ethyl silicate) 40 (manufactured by Colcoat ■, trade name)] inorganic zinc obtained by mixing an organic solvent and zinc powder Although the powdered paint does not gel even after one year or more and has excellent storage stability, the coating film formed from it does not harden at all and cannot fully exhibit the necessary functions as an inorganic zinc paint.

~5 alkyl groups. ) and/or an alkylsilicate bond, neither of which has a silanol group in the molecule. Specifically, examples thereof include orthomethyl silicate, orthoethersilicate, ortho n-propyl silicate, ortho n-propyl silicate, and polyalkyl silicates obtained by partially condensing these orthoalkyl silicates. Among these, 40 (trade name of Nippon Colcoat ■ and Tama Kagaku Kogyo ■), which is commercially available as a condensation product of orthoethylsilicate, ortho-n-propylsilicate, orthomethylsilicate, and orthoethylsilicate, in particular, has an ethyl group. (having a molecular weight of 200 to 7.000) is preferred. These are 1a! Or two or more types can be used in combination.

全く満足しないという欠点を生じるので好ましくない。The zinc chloride compounded in the inorganic zinc powder paint of the present invention is based on the amount of zinc chloride contained in the paint.
SiOz conversion value) 30 to 1 for 100
The amount is 20 parts by weight, preferably 40 to 100 parts by weight. If the amount of zinc chloride is less than 30 parts by weight, the hardness of the coating after painting will be very soft, and even if it dries for a long time, the hardness will not increase, and the functional level as an inorganic zinc powder coating will be completely lost. This is not desirable because it causes the drawback of not being satisfied.
一方、配合量が、１２０重量部より多いものは、該塗料
