The present invention relates to a rust-preventing and corrosion-preventing paint composition that has excellent water resistance, moisture resistance, weather resistance, and drying properties, and has low temperature sensitivity. In this specification, wax refers to waxes excluding petrolatum and lanolin, such as petroleum-based waxes such as paraffin waxes and microcrystalline waxes, coal-based waxes, animal and plant-based waxes, and synthetic waxes. Generally, the so-called history is manufactured by mixing petrolatum oxide, wax oxide, metal salts or esters thereof, metal salts of lanolin, etc. with petroleum sulfonic acid metal salts, petrolatum, lanolin, wax, etc., and bituminous substances, and adding a medium. By adding bituminous substances to blue-modified wax-based rust- and corrosion-inhibiting paints, costs can be reduced without reducing the rust- and corrosion-inhibiting properties.
In addition, it does not contain harmful anti-rust pigments such as chromium and lead compounds, and has excellent anti-rust and anti-corrosion effects and adhesion of paint films, so it is a rust-preventive agent for various metal products such as vehicles, machinery, and various parts. It is widely used as However, the above-mentioned bituminous modified wax-based anti-rust and anti-corrosion paints contain relatively highly polar substances such as petrolatum oxide, oxidized wax, metal salts or esters thereof, lanolin metal salts, petroleum sulfonic acid metal salts, and bituminous substances. Because of this, the paint film has poor water resistance and humidity resistance, causing discoloration (generally black color changes to brownish-brown due to deterioration) and swelling, and poor weather resistance, which may cause significant yoking and swelling of the paint film when exposed outdoors.
It has the disadvantage of causing cracks, cracks, etc. In addition, because the paint contains particularly bituminous substances, the paint film is highly sensitive to temperature, becoming soft and sticky at high temperatures in the summer, while becoming hard, brittle, and flexible at low temperatures in the winter. It has the disadvantage of deterioration, and also has the disadvantage of poor drying properties because it is a mixture of substances with large differences in melting points. As mentioned above, conventional bituminous modified wax-based anti-rust and anti-corrosion paints have many drawbacks in terms of performance, and although improvement of these drawbacks has been a long-standing challenge, methods for improving these drawbacks include: At present, it is hardly developed. In view of the above-mentioned current situation, the present inventor conducted extensive research to improve the various drawbacks of the conventional bituminous modified wax-based anti-rust and anti-corrosion paints. The present inventors have discovered that all of the above-mentioned drawbacks can be overcome without impairing the excellent rust- and corrosion-preventing effects and coating film adhesion that they originally possess, and have completed the present invention. That is, the present invention provides at least one of petrolatum oxide, wax oxide, metal salts or esters thereof, and metal salts of lanolin, petrolatum, at least one of lanolin and wax, metal salts of petroleum sulfonates, bituminous substances, and media. A styrene-ethylene/butylene-styrene copolymer (with a molecular weight of 30,000 to 90,000 and a weight ratio of styrene:ethylene/butylene in the molecule of 5:95 to 40:60 in a composition mainly composed of Below, S-E・B-S
copolymer) in all components other than the medium.
It relates to a rust-preventing and corrosion-preventing paint composition characterized by containing 10% by weight. Petrolatum oxide, wax oxide, metal salts or esters thereof, metal salts of lanolin, petrolatum, lanolin, wax, and metal salts of petroleum sulfonic acid used in the present invention include those that can be generally used for rust- and corrosion-proofing paints. All can be used without any particular limitations. Furthermore, the metal of each metal salt in each of the above components is not particularly limited, and many metals can be used, such as alkali metals such as sodium, potassium, and lithium, alkaline earths such as calcium, barium, and strontium. Examples include similar metals, molybdenum, zinc, and the like. Among these, alkali metals and alkaline earth metals are preferred from the viewpoint of rust and corrosion prevention effects. Of course, these metal salts may contain one kind of metal or two or more kinds of metals. Furthermore, any bituminous substance that can be used as a modifier for rust-proofing and corrosion-proofing paints can be used without particular limitation, such as asphalt, coal tar, coal tar pitch, and the like. The blending composition of each of the above components does not need to be special, and may be the same as the blending composition of conventional bituminous modified wax-based rust- and corrosion-preventing paints. That is, for 100 parts by weight of at least one of petrolatum oxide, wax oxide, metal salt or ester thereof, and metal salt of lanolin, usually about 3 to 800 parts by weight of at least one of petrolatum, lanolin, and wax.
Usually about 3 to 800 parts by weight of petroleum sulfonic acid metal salt and about 3 to 20,000 parts by weight of bituminous material are mixed. In the present invention, it is essential to contain a specific amount of the SE/B-S copolymer. S-E・B
The -S copolymer is a block copolymer having a molecular structure in which polystyrene, which is an end block, is bonded to both ends of an ethylene-butylene copolymer, which is an intermediate block. The intermediate block, ethylene-butylene copolymer, can be obtained, for example, by hydrogenating a copolymer of 1,2-butadiene and 1,3-butadiene. The S-E/B-S copolymer used in the present invention has a molecular weight of 30,000 to 90,000, and a weight ratio of styrene:ethylene/butylene in the molecule of 5:95.
~40:60 preferably 10:90~35:65. If the molecular weight is less than 30,000, the physical properties will deteriorate and the original effect of addition will not be obtained, and styrene:
If the weight ratio of ethylene to butylene is less than 5:95, the coating film will remain sticky and drying properties will not be improved. Furthermore, if the molecular weight is greater than 90,000 or the weight ratio of styrene:ethylene/butylene is greater than 40:60, the compatibility with other components used in the present invention will be poor. As the S-E/B-S copolymer used in the present invention, for example, the commercially available “Krayton G-
1650", "Clayton G-1652", "Clayton G-
1657'' (manufactured by Ciel Chemical Co., Ltd.), etc. can also be used. In addition, in the present invention, the above-mentioned specific S-E.
0.05 to 10 of the B-S copolymer in all components other than the medium
It is necessary to contain it in % by weight, preferably 0.1 to 8% by weight. If it is less than 0.05% by weight, the desired effect of the present invention cannot be obtained, and if it is more than 10% by weight, the adhesion of the coating film will be poor. In the composition of the present invention, in addition to the above-mentioned components, various components commonly used in this type of composition can be used as appropriate.
Such components include, for example, petroleum resins, cyclized rubber, coumaron indene resins, polybutene resins, alkyd resins, synthetic resins that are compatible with each of the above components such as acrylic resins, neutral oils, minerals such as liquid paraffin, etc. Animal and vegetable oils and fats such as oil, boil oil, stand oil, linseed oil, and fish oil, coloring pigments such as titanium dioxide, red iron, and carbon black, extender pigments such as talc, calcium carbonate, kaolin, and clay, aluminum powder, zinc powder, and stainless steel powder. Metal powders such as flaky iron oxide, glass powders, glass flakes, porcelain powders, mica flakes, etc.
Examples include antifoaming agents, dispersants, ultraviolet absorbers, and antioxidants. The composition of the present invention is produced by adding an appropriate amount of medium to each of the above-mentioned components, and mixing the mixture at room temperature or under heating using, for example, a dissolver. Organic solvents or water are used as the medium.
The amount of media used varies depending on the purpose and is not constant. The organic solvent is not particularly limited and may be appropriately selected from various known solvents commonly used in this type of paint, but S-
Those having good solubility with the E/B-S copolymer are preferred, such as mineral spirits, rubber volatile oil, aliphatic or aromatic hydrocarbon solvents such as xylene, toluene, decalin, and tetralin, and methyl isobutyl ketone. , methyl-n-amyl ketone, ketone solvents such as cyclohexanone, butyl acetate,
Examples include ester solvents such as amyl acetate and isopropyl acetate, and ether solvents such as ethyl cellosolve and butyl cellosolve.
Use seeds or a mixture of two or more. When water is used as a medium, the solid content of each compounded component is usually heated to melt at about 60 to 90°C and mixed using a dissolver, homogenizer, etc., to produce petrolatum oxide, petrolatum, lanolin, oxidized wax, Surfactants such as sodium oleate, sodium dodecylbenzenesulfonate, polyoxyethylene nonyl phenyl ether, which are commonly used for emulsification of waxes, etc., and protective colloids such as dextrin, casein, polyvinyl alcohol, etc. are added. , add water or warm water while stirring to form an aqueous dispersion. Furthermore, an organic solvent can also be used in combination to reduce the viscosity of the aqueous dispersion, improve storage stability, film-forming properties, and the like. The rust- and corrosion-preventing paint composition of the present invention thus obtained can be suitably applied by any of the commonly used coating methods, such as air spraying, airless spraying, brushing, roller, dipping, etc. It can be suitably used for all kinds of metals that require oxidation, such as vehicles, machines, various parts, containers, and various plants. The rust-preventing and corrosion-preventing paint composition of the present invention eliminates all the drawbacks of conventional bituminous modified wax-based rust-preventing and corrosion-preventing paints, while still retaining the advantages of the paints. That is, the rust-preventing and corrosion-preventing coating composition of the present invention not only has excellent rust-preventing and corrosion-preventing effects and adhesion of the paint film, but also has excellent water resistance and moisture resistance, so that the paint film does not discolor or swell. In addition, because it has excellent ozone resistance, weather resistance is significantly improved, and the coating film will not suffer from choking, cracking, cracking, etc. even when exposed outdoors. Furthermore, since the temperature sensitivity of the coating film is low, it does not become sticky at high temperatures or become brittle and crack at low temperatures. Furthermore, it has excellent drying properties. The reason why such remarkable effects can be obtained according to the present invention is due to the use of a specific amount of the above-mentioned specific SE/B-S copolymer. Although the mechanism is not clear at present, it is presumed as follows. That is, the ethylene-butylene copolymer, which is the intermediate block of the S-E/B-S copolymer, is a physically and chemically stable polyolefin and has low polarity, resulting in improved water resistance, moisture resistance, and weather resistance. Moreover, since the copolymer as a whole has excellent heat resistance and flexibility, the temperature sensitivity of the coating film is reduced, and it is thought that the polystyrene blocks on both ends improve drying properties. Also,
The S-E/B-S copolymer has very good affinity with other components used in the present invention, so it can be dispersed uniformly, so even if the content is as small as 0.05% by weight, It is also believed that the above effects can be achieved. EXAMPLES Hereinafter, the present invention will be explained in more detail with reference to Examples and Comparative Examples.
