Description
Technical field
The present invention relates to chemical powder paint field, particularly the special-purpose high tenacity powder coating of a kind of antitheft door.
Background technology
Along with the continuous expansion of powder coating Application Areas, powder coating is widely used in the application in the fields such as all kinds of antitheft doors, aluminium section bar, file cabinet.Environment friendly and pollution-free because of powder coating, coating efficiency is high, and film performance is excellent, and nowadays metal anti-theft door application almost all adopts powder spraying.
Antitheft door powder coating has three kinds of forms conventionally: 1, the powder coating direct spraying once shaped such as wrinkle, fine arts type decorative pattern, sand streak, metal pattern; 2, powder coating is that primary coat is hot transfer printing molded again; 3, powder coating is the moulding of primary coat outer cover paint.
The conventional spraying coating process of the hot transfer printing of antitheft door is clean → cover of steel plate pre-treatment → moulding → spraying → baking → cementing → paster → baking → paper-tear picture → water mill paint → baking → finished product.Antitheft door is sandwich structure, and Sandwich materials is mainly honeycomb paper, vermiculite board, rock wool, glass wool etc.While spraying after antitheft door moulding because of in have that sandwich of layers quality is heavier often to be needed to expend larger labor force it is hung up to spraying coating line, while toasting after door electrostatic spraying, can make the passive heat absorption of Sandwich materials, not only make heat-up rate and the production efficiency of workpiece reduce, also make the carbonization of Sandwich materials honeycomb paper, lose original effect and even cause potential safety hazard.On the other hand, in use, existing powder coating is sprayed on sheet metal or all kinds of antitheft door after film-forming, then while carrying out 90 °～180 ° of machine-shapings such as die mould, flanging, roll-in, bound edge sealing, when powder coating coating thickness reaches 50～90 microns, will ftracture.Antitheft door steel plate thickness used is 0.4～1.5 millimeter, 50～90 microns of powder coating coating thicknesses.
High tenacity powder coating is useful on the Workpiece painting fields such as vehicle filter core device, spring at present, although have certain toughness, can't meet the requirement of the first application reshaping of antitheft door.The special-purpose high tenacity powder coating of a kind of antitheft door of our company's exploitation, can realize spray technology: steel plate pre-treatment → spraying → baking → vacuum transfer printing → bending and molding → finished product.Workpiece steel plate first sprays while carrying out 90 °～180 ° of machine-shapings such as die mould, flanging, roll-in, bound edge sealing after film forming again, when powder coating coating thickness reaches 50～90 microns, can not ftracture.The Application and Development of this tough powder paint reaches energy-saving and cost-reducing object by greatly improving spray efficiency.
Summary of the invention
The present invention is directed to the easy to crack or technological deficiency such as come off of filming while carrying out the machine-shapings such as die mould, flanging, roll-in, bound edge sealing on the antitheft door of prior art after application, a kind of high tenacity powder coating being sprayed on antitheft door is provided, make antitheft door when the machine-shapings such as die mould, flanging, roll-in, bound edge sealing, when coating thickness is 50～90 microns, can not ftracture or come off yet.Meanwhile, for antitheft door provides the making flow process of more optimizing.
