摘要： PURPOSE:To obtain strong adhesion between a steel sheet and coating film and to obtain excellent workability and corrosion resistance by forming a chro mate treatment layer, primer layer and topcoat layer on the surface of the steel sheet having an alloy hot-dip galvanizing layer. CONSTITUTION:On one surface of a steel sheet 5 having an alloy hot-dip galva nizing layer 4, a chromate treatment layer 3 is provided as the lowermost layer having 10-100mg/m chromium, and then a primer layer 2 of 1-10mum thickness comprising epoxy resin or polyester resin or modified resin of these resins is formed thereon. Further, a coating layer 1 as the topcoat is provided to 10-50mum dry film thickness essentially comprising polyester resin or its modified resin, with 15-50 deg.C glass transition temp., >=25% elongation and >=0.5kgf/mm tensile strength. Thereby, strong adhesion is obtained between the steel plate and the coating film, and the obtd. precoated steel sheet has excellent workability and corrosion resistance.

摘要： PURPOSE:To obtain the precoated steel plate having matte appearance and a cloth like feeling and showing sufficient decorative properties without showing a cool feeling peculiar to a steel plate by providing a film formed from a paint composition containing an elastic resin binder, a crosslinked colored globular resin powder and an inorg. matter powder and an inorg. matter powder to the uppermost layer. CONSTITUTION:A crosslinked colored globular resin powder and an inorg. matter powder are contained in a paint composition formed into a film on the uppermost layer. The mean particle size of the crosslinked colored globular resin powder is 20 - 150mum and the compounding ratio thereof is 30% or more by vol. of the solid of the film. The mean particle size of the inorg. matter powder is 5 - 150mum and the compounding ratio thereof s 5% or more by vol. of the solid of the film. When the mean particle size is below 5 mum, it becomes difficult to improve matte properties, scratch resistance and the touch by the adjustment of the surface roughness of the film. This pre-coated steel plate can be formed by using a cold rolled steel plate, a zinc type plated steel plate or one obtained by applying chemical forming treatment thereto by phosphoric acid or chromate as a base plate.

摘要： PURPOSE:To provide a highly corrosion resistant steel material having high corrosion resistance by forming an amorphous alloy layer on the surface layer part of a steel material. CONSTITUTION:An alloy which is liable to turn amorphous is beforehand coated or melt-sprayed on the surface of a steel material in such a way as to make a 50- 300mu layer. The coating is carried out by adding a binder to said alloy powder and preparing the mixture into a slurry. Thence, a laser or electron beam is irradiated to the coated or melt-sprayed layer of said easy-to-turn amorphous alloy from is surface to locally heat the same at high temps, whereby the coated or melt-sprayed layer is melted to about 50-300mu from the front surface. Following to this, the working point is moved, whereby the melting of the entire part of the work is completed. The molten part is quickly cooled by the heat transfer of the base metal or by another force cooling. It is possible to cool said part at >=10 deg.C/sec cooling rates by controlling heating, or a force cooling method for the thickness of the base metal, whereby the composite steel material of high corrosion resistance having the amorphous or pseudo-amorphous alloy laye on the surface of the steel material is obtained.

摘要： PURPOSE:To obtain a mat precoated steel sheet with excellent formability prepd. by high speed coating by using a coating prepd. by compounding a speci fied resin with a specified curing agent and a specified colored spherical resin powder. CONSTITUTION:For a precoated steel sheet, a polyester resin and/or an acryl polyester resin with a number average MW of 10,000-30,000, a glass transition temp. of 10-60 deg.C and an OH value of 5 or larger as a base is compounded with an alkyletherified melamine resin and/or an isocyanate compd. blocked with an oxime type blocking agent as a curing agent. In addition, the precoated steel sheet has a coating film formed from a coating compsn. prepd. by compounding 30-80vol.% crosslinked and cured colored spherical resin powder with a mean particle diameter of 20-150mum in the solid content of the coating as the outermost layer. If the number average MW of the base resin is smaller than 10,000, crack and peeling of the coating easily occur and if it exceeds 30,000, dispersibility of the colored spherical resin powder becomes inferior. If the glass transition temp. is lower than 10 deg.C, a scratch is easily produced on the coating film and if it exceeds 60 deg.C, crack and peeling of the coating easily occur.
