This invention relates to a method for producing an aqueous emulsion suitable as a moisture-proofing and waterproofing agent for paper, fibers, cement products, and gypsum products. or an aqueous emulsion force-emulsified in water in the presence of an aqueous solution of a protective colloid selected from the group consisting of alkali salts of partial alkyl esters of styrene-maleic acid copolymers (hereinafter referred to as styrene-maleic acid copolymers). (2) A method for producing an aqueous emulsion in which a synthetic rubber emulsion is added to the aqueous emulsion obtained in (1) above, and (3) A method for producing an aqueous emulsion by adding a synthetic rubber emulsion to the aqueous emulsion obtained in (1) above. The present invention relates to a method for producing an aqueous emulsion in which a synthetic rubber emulsion is added to an aqueous emulsion obtained by forced emulsification in water in the presence of a polymeric protective colloid. Hitherto, aqueous emulsions of hydrocarbon resins, waxes, and fatty acids have been widely used as water-repellent and waterproof agents for paper and textiles, and as waterproofing and waterproofing agents for building materials. However, this aqueous emulsion required the use of a large amount of surfactant during its production. The presence of surfactants has a negative effect on the water repellency and waterproofing properties of aqueous emulsions due to their inherent hydrophilic properties, and the presence of surfactants has a negative effect on the water repellency and waterproofing properties of aqueous emulsions, making it difficult to fully utilize the performance of hydrocarbon compounds, which are the main component of waterproofing agents. I couldn't perform. This invention involves pre-emulsifying wax or paraffin hydrocarbons in water in the presence of a protective colloid of styrene-maleic acid copolymers by mechanical means without using a surfactant, and then force-emulsifying them at high temperatures. A method for producing an aqueous emulsion in which a synthetic rubber emulsion is added to the aqueous emulsion obtained as described above, and a method for producing an aqueous emulsion by adding a synthetic rubber emulsion to the aqueous emulsion obtained as described above, and a method for producing a synthetic hydrocarbon resin or wax by mechanical means without using a surfactant. Synthetic rubber emulsion is added to the aqueous emulsion obtained by pre-emulsifying hydrocarbons such as or paraffins in water in the presence of a protective colloid of styrene-maleic acid copolymers, followed by forced emulsification at high temperature, and then quenching. A method for producing an aqueous emulsion is provided. The styrene-maleic acid copolymers used in this invention do not emulsify with waxes or the like simply by stirring and mixing. For this reason, it is forcibly emulsified under high pressure. The aqueous emulsion obtained by this invention is a fiber,
Apply to paper, especially cardboard liner paper, to make it water repellent.
It is used for the purpose of imparting waterproofness and to impart waterproofness and water resistance to cement and gypsum products, especially when added during mixing in the manufacture of gypsum board boards. Since high temperatures of about 160 to 180°C are encountered in the lamination process of corrugated board manufacturing, conventional water-based emulsion waterproofing agents often suffer from thermal deterioration due to surfactants. However, in the aqueous emulsion according to the present invention, such thermal deterioration is not observed, and the slipperiness of the coated surface is also improved. If the aqueous emulsion obtained in this invention is used as a moisture-proofing agent,
The moisture permeability of the resulting paper can be reduced to 1/2 to 1/20, depending on the amount of coating. It also has the feature of making it easy to collect waste paper. Generally, when waterproofing gypsum products, an alkylbenzene sulfonate surfactant is used as a foaming agent. Conventional waterproofing agents have disadvantages such as making the foam non-uniform, slowing down the curing speed of plaster, and reducing product strength. The aqueous emulsion according to the invention did not exhibit the above-mentioned drawbacks when used in gypsum products. Examples of paraffin and waxes include paraffin wax, oxidized paraffin, polyethylene wax, montan wax, carnauba wax, and microcrystalline wax. Fatty acids include higher fatty acids such as stearic acid and oleic acid, and metal soaps thereof include calcium, magnesium, zinc, aluminum and zirconium salts. The synthetic hydrocarbon resin used in this invention is produced during naphtha decomposition and has a boiling point range of -20 to 250℃.
There are products obtained by polymerizing C 5 to C 9 fractions by Friedel-Crafts reaction that have a softening point ranging from a liquid at room temperature to a solid at about 150°C. Examples of unsaturated carboxylic acids used for modifying hydrocarbon resins include maleic acid, maleic anhydride,
There are α,β-unsaturated polybasic acids such as fumaric acid and itaconic acid, and unsaturated monocarboxylic acids such as acrylic acid and methacrylic acid, which are added by mixing with hydrocarbon resin and heating reaction at 180 to 220°C. get something Alcohols used for esterification include monohydric alcohols such as methyl alcohol, ethyl alcohol, propyl alcohol, octyl alcohol, cetyl alcohol and stearyl alcohol, dihydric alcohols such as ethylene glycol, propylene glycol and butylene glycol, and others. There are polyhydric alcohols such as glycerin and pentaerythritol, and the esterification reaction is carried out by heating the unsaturated acid adduct and alcohol at 180-220°C, and the degree of esterification is up to half ester. Styrene-maleic acid copolymers are used as the water-soluble polymer compound used as the protective colloid, and inorganic or organic alkali salts of copolymers having a molecular weight of 1,000 to 5,000 are preferred. As the alkali, caustic potash, caustic soda, ammonia, morpholine, dimethylamine, etc. are used, and caustic potash is particularly preferred. In particular, when aqueous emulsions using styrene-maleic acid copolymers or salts of their alkyl esters as protective colloids are used as waterproofing agents for cement or plaster products, they react with calcium ions to form water-insoluble calcium salts. As a result, the water resistance of the treated product is significantly improved. Furthermore, the high hardness of the styrene-maleic acid copolymer resin also improves the flexural strength of the treated product. The synthetic rubber emulsions used in this invention include emulsions of butadiene rubbers, such as styrene-butadiene rubbers, acrylonitrobutadiene rubbers, and methacrylate-butadiene rubbers. The proportions of the raw materials used are 80 to 97 parts by weight of the hydrocarbon and 20 to 3 parts by weight of the styrene-maleic acid copolymer salt. A predetermined amount of raw materials are mixed, melted, and added to an aqueous solution of a polymer compound for protective colloid.
Pre-emulsify at 200°C using a powerful stirrer with high shear force and under pressure if necessary. Continue 100-500Kg/
Forced emulsification is carried out by passing at least once through a piston-type high-pressure emulsifier or a colloid mill under a pressure of 200 to 300 Kg/cm 2 , preferably 200 to 300 Kg/cm 2 , and then quenched to obtain the desired fine-particle aqueous emulsion. This emulsion is obtained at a high concentration of about 40%. A synthetic rubber emulsion is mixed into the aqueous emulsion thus obtained, the amount of which is selected so that 10 to 50% of the solid content of the final emulsion is rubber emulsion particles. Furthermore, in the aqueous emulsion of this invention,
The proportion of raw materials when using synthetic hydrocarbon resin is
3 to 80 parts of synthetic hydrocarbon resin, preferably 5 to 50 parts
parts, 92 to 20 parts of hydrocarbon, preferably 90 to 60 parts, and 2 to 20 parts, preferably 5 to 60 parts of water-soluble polymer compound.
Pre-emulsify and force emulsify 15 parts as above. Next, a synthetic rubber emulsion is mixed into the resulting aqueous emulsion so that the final emulsion has a synthetic rubber solid content of 3 to 70%, preferably 5 to 50%. Aqueous emulsions containing synthetic rubber can further improve the water resistance, water resistance and flexural strength of treated paper, cement or plaster products due to the film-forming properties of the rubber and its elasticity. The aqueous emulsion produced according to the present invention can be applied to paper and fibers, especially corrugated board liners, to improve their moisture-proofing and waterproofing properties, and any known coating methods such as roll coating, brush coating, and dipping can be used. used. Furthermore, when manufacturing gypsum products, especially gypsum board boards, an aqueous emulsion can be added to the water used to knead the gypsum to improve the waterproofness and water resistance of the product. Therefore, the obtained gypsum board board can also be used in places where water is used, such as bathrooms, washrooms, and kitchens. This invention will be explained in more detail by the following examples. Example 1 Production of dispersant 100 parts of styrene-maleic acid copolymer monomethyl ester, 20 parts of caustic potassium, and 1800 parts of water were placed in an emulsifying pot with a stirrer, and dissolved at 60°C for 3 hours to obtain a dispersant solution. . Production of aqueous emulsion 50 parts of paraffin wax with a melting point of 160㎓ and 50 parts of polyethylene wax were mixed and melted at 140°C. Meanwhile, the above dispersant solution was heated to 140°C in an autoclave. The melt and the dispersant solution were mixed at a solid content ratio of 95:5 to perform preliminary emulsification. Then, using a piston type high pressure emulsifier, 400Kg/
A 45% concentrated emulsion was obtained by passing under a pressure of cm 2 . Example 2 100 parts of paraffin wax with a melting point of 125〓 was melted at 90°C, and this and the dispersant solution of Example 1 (60°C) were mixed at a solid content ratio of 90:10 and stirred to pre-emulsify. I went. Next, using a piston type high pressure emulsifier
A 40% strength aqueous emulsion was obtained by passing it twice under a pressure of 200 Kg/cm 2 . Performance Test The water-based emulsion obtained in the above example was tested for its waterproofing effect on gypsum products. Test method Raw materials: β-type hemihydrate gypsum water-toner ratio: 75% Waterproofing agent addition amount: 2%, 3%, 4% (solid content) Test piece: 20 mm x 20 mm x 80 mm Drying method: 2 hours at room temperature and 50°C Water absorption rate (%) = (B-A)/A x 100 A: Weight of test piece after drying at 50℃ for 24 hours B: Weight of test piece after being immersed in water at 25℃ for a specified time Measured water absorption rate are shown in the table below.
