This invention relates to a method for producing an aqueous dispersion of a fatty acid metal salt, in particular, reacting a higher fatty acid with a metal hydroxide or metal chloride in water, and pre-emulsifying the mixture by mechanical stirring in the presence of a small amount of a surfactant. The article then goes on to describe a method for producing an aqueous dispersion of fatty acid metal salts, which is mechanically and forcibly dispersed using a piston-type high-pressure emulsifier. Conventionally, aqueous dispersions of higher fatty acid metal salts are
It is widely used as an additive to coating liquids for the purpose of preventing flowering and dusting during the production of coated paper and coated paperboard, especially during calendering. On the other hand, it is also used as a water-resistant agent for various building materials such as gypsum products, cement products, cement boards, silicon boards, pulp cement boards, magnesium carbonate boards, gypsum slag boards, particle boards, and chipboards. The fatty acid metal salts used above were obtained by metathesis reaction of a higher fatty acid soda solution with a metal salt such as calcium chloride, which required washing, dehydration, drying and pulverization of the reaction product. Alternatively, higher fatty acids and metal hydroxides or chlorides, such as calcium hydroxide or calcium chloride, are reacted directly in the melt, with the product being cooled and ground. Furthermore, an aqueous dispersion was obtained by dispersing the metal salt thus obtained in water in the presence of a surfactant. However, the resulting aqueous dispersion had drawbacks such as unstable viscosity and easy foaming. Furthermore, it requires a large amount of surfactant, and due to its hydrophilic nature, when used as a water-resistant or water-repellent agent, its performance is often insufficient. The present inventors have conducted extensive research on a method for producing a high-performance aqueous dispersion of higher fatty acid metal salts free from the above-mentioned defects. As a result, higher fatty acids and group metal hydroxides or chlorides are reacted in water to produce nonylphenol, stearyl alcohol,
Polyoxyethylene ether of cetyl alcohol and oleyl alcohol (ethylene oxide 7
~25 moles of adduct) or an anionic surfactant selected from the group consisting of alkali sulfosuccinates, alkali succinates and alkali polyoxyethylene ether sulfonates of nonylphenols. We succeeded in obtaining a high-performance aqueous dispersion of higher fatty acid metal salt by pre-emulsifying it by mechanical stirring in the presence of a small amount of the agent and then forcefully dispersing it under high pressure using a piston-type high-pressure emulsifier. . The fatty acid metal salt used in this invention means one that does not contain free carboxylic acid in which 100% of the carboxylic acid groups are converted into metal salts. Therefore, the metal hydroxide or metal chloride used in the reaction is used in an equimolar ratio or more to the fatty acid. The higher fatty acids used in this invention are saturated or unsaturated fatty acids, such as caproic acid, caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, and rosin acid. These fatty acids may be used alone or in combination of two or more. Metal hydroxides and metal chlorides have the formula M
(OH) 2 , MCl 2 , where M is Mg, Ca, Ba
Zn is an alkaline earth metal and a metal of the Table Group. As surfactants, nonionic and anionic surfactants whose lipophilic groups are residues of nonylphenol or higher alcohols are used. Nonionic surfactants include nonylphenol and polyoxyethylene ethers of stearyl alcohol, cetyl alcohol and oleyl alcohol (with 7 to 25 moles of ethylene oxide). Examples of anionic activators include alkali sulfosuccinates of nonylphenol, alkali succinates, and alkali polyoxyethylene ether sulfonates. These surfactants are particularly stable against fatty acid metal salts and effectively act on their dispersion. One type or two types of surfactants may be used in combination. In preparing the dispersant of the present invention, the fatty acid is first dissolved in warm water, a small amount of surfactant is added, and then the metal hydroxide or metal chloride is added.
Otherwise, add the metal hydroxide or metal chloride and surfactant to the hot water, then add the fatty acid. In either method, the reaction proceeds rapidly under stirring. The resulting dispersion is predispersed by processing it in a suitable dispersion machine, such as a TK mixer, disper mill or colloid mill. Then 100-500Kg/ cm2 , preferably 200-300Kg/ cm2
At least one piston-type high-pressure emulsifier under the pressure of
Multiple passes and quenching yield an aqueous dispersion with particle size less than 3 microns, mostly less than 1 micron. The dispersion of the present invention has an extremely fine particle size, so it is extremely stable, and can be uniformly distributed on the object to be treated, thereby imparting good water resistance and water repellency. In the present invention, it is sufficient that the temperature of water, which is a reaction medium during metal salification of fatty acids, is 10° C. higher than the melting point of the commonly used fatty acids. The component proportions in the aqueous dispersion are 90 to 99 parts of fatty acid metal, preferably 96 to 98 parts, and 10 to 1 part of surfactant, preferably 2 parts.
~4 parts (parts by weight). The invention will be explained in further detail in the following examples. Example 1 682.3 g of water, 6 g of nonylphenol polyoxyethylene ether (20 moles of ethylene oxide), and 36.4 g of slaked lime were placed in a stainless steel container, and heated to 85°C.
275.3 g of stearic acid was gradually added under stirring. After the reaction was completed, the mixture was pre-emulsified with a TK mixer and passed through a piston-type high-pressure emulsifier twice at a pressure of 200 kg/cm 2 to obtain an aqueous dispersion with a concentration of 30%. Example 2 741.1 g of warm water, 59.4 g of slaked lime, and 10 g of a nonionic surfactant (polyoxyethylene cetyl ether, ethylene oxide addition number: 10 moles) were placed in a stainless steel container, heated to 80°C, and then mixed with olein while stirring. After completing the reaction by alternately charging 134.8 g of acid and 314.7 g of stearic acid, 10 g of anionic surfactant (sodium polyoxyethylene sulfonate) was added, pre-dispersion was performed using a colloid mill, and 200 kg/cm 2 2 piston type high pressure emulsifier at the pressure of
A stable aqueous dispersion with a product concentration of 50% was obtained by multiple passes. Example 3 575.6 g of warm water, 15 g of nonionic surfactant (polyoxyethylene stearyl ether, 9 moles of ethylene oxide addition), 256.1 g of stearic acid
Prepare and heat to 85℃ to melt. Next, 62.2 g of zinc chloride diluted 3 times with warm water was gradually added while stirring to complete the reaction. After preliminary dispersion in a colloid mill, the mixture was passed once through a piston-type high-pressure emulsifier at a pressure of 300 Kg/cm 2 to obtain a stable aqueous dispersion with a product concentration of 30%. The results of tests using the aqueous dispersions obtained in these Examples in the production of pulp cement boards and coated paper are shown below. 1 Comparative test on pulp cement board Raw materials Portland cement 55 parts Asbestos 35 parts Pulp 10 parts Test piece 8 x 50 x 100 mm Amount of water-resistant agent added 0.6% of raw material (solid content equivalent)
