摘要： A composition for forming insulating films on electrical steel sheets includes a (meth)acrylate ester polymer, modified into a polymer containing an ethylenic unsaturated carboxylic acid component as an essential copolymerizable component, optionally with other copolymerizable vinylic compound components. The composition is used in the form of an aqueous emulsion with or without methacrylate ester base polymer powders. The composition has low expandability and coatability and provides an improved film. Especially when the composition contains methacrylate ester base polymer powders, improved weldability is achieved and high-quality coated steel sheet products are provided. A method of forming the insulating films is also described.

摘要： The present invention relates to a method for forming insulating films on electromagnetic steel plates.Conventional films obtained by coating only an inorganic component such as a chromate, forming an organic-component film on an inorganic-component film or coating a mixture of both components individually have had disadvantages such as the occurrence of crateriform pinholes, reductions in punching properties, rises in the cost and decreases in interlayer resistance and the like.The present invention provides a method wherein a composition obtained by combining an acrylic resin and/or an acryl-styrene resin and guanamine resin as the organic components with an inorganic substance composed mainly of a chromate is coated and dried on an electromagnetic steel plate to form thereon an insulating film.According to the present invention, it is possible to form an insulating film which has excellent film properties and is free from said disadvantages.

摘要： A method of manufacturing a vinyl chloride-coated steel sheet involving the steps of coating electron ray curable adhesives on the surface of a thin metal sheet, such as a zinc plated steel sheet or cold rolled steel sheet, laminating a vinyl chloride film of decorative and corrosion resistant protecting properties to the coated surface and irradiating the upper surface of the coated sheet with electron rays thereby bonding the film with the metal sheet, wherein the vinyl chloride film is formed by applying a calendering or extruding process to a blend including a vinyl chloride resin obtained by suspension polymerization and from 20 to 40 parts by weight of a plasticizer, dialkyl tin mercaptide type stabilizer, an acryl oligomer type lubricant and optionally, pigments and other ingredients.Combined use of the dialkyl tin mercaptide stabilizer and the acryl oligomer lubricant has been found to be particularly suitable for electron ray irradiation, as well as to the subsequent UV-ray exposure which would otherwise cause significant degradation in the vinyl chloride coating.
