Description
Technical field
The present invention relates to a kind of color coated steel sheet, specifically the solid PVDF color coated steel sheet of a kind of high guarantor.
Background technology
Day by day serious along with environmental problem, various pollutions are more and more serious to the corrosion of construction material, and in order to extend service life, the serious factory of some environmental corrosions need to be used high weather-proof construction material as power plant, chemical plant and some Important Project.
PVDF color coating coil of strip is used the color coating coil of strip product of PVDF (polyvinylidene fluoride) production of resins, and generally producing thickness is 20 μ m, and Bao Gunian is limited to 15~20 years.In order to increase the weatherability of PVDF color coating coil of strip, need to guarantee that in paint film, PVDF resin content needs more than 70%, and use inorganic ceramic pigment, just can reach certain weatherability, protect the solid time limit and can reach at most 20 years.
At present, produce high weather-proof, the high PVDF product of protecting the solid time limit and need use high weather-proof high-end PVDF resin as KYNAR500 or HYLAR5000, guarantee that paint thickness is more than 18 μ m, and need to use inorganic ceramic pigment.Coating price costliness and color are limited.
Summary of the invention
Technical problem to be solved by this invention is to provide the solid PVDF color coated steel sheet of a kind of high guarantor.This color coated steel sheet has stronger weatherability, wear resistence, protects the solid time limit more of a specified duration.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
The solid PVDF color coated steel sheet of a kind of high guarantor, comprise basic unit, the front of described basic unit is followed successively by preprocessing layer, prime coat, top coat layer and layer of varnish from inside to outside, the back side of described basic unit is followed successively by preprocessing layer, prime coat and top coat layer from inside to outside, preprocessing layer outside described basic unit positive and negative is that passivating solution applies formation, the prime coat thickness in described basic unit front is 65~70 μ m, and its material is polyurethane primer; Described top coat layer thickness is 35~40 μ m, and its material is PVDF finish paint; Described layer of varnish thickness is 10~15 μ m, and its material is PVDF varnish.
Wherein, the polyurethane priming paint of 65~70 μ m has good corrosion resistance.
The PVDF of 35~40 μ m (polyvinylidene fluoride) finish paint has good weatherability.
The PVDF of 10~15 μ m (polyvinylidene fluoride) varnish, has good wearability.
In order to obtain the solid time limit of more excellent guarantor, the gross thickness of prime coat, top coat layer and the layer of varnish in described basic unit front is less than 120 μ m, and the prime coat thickness that preferred scheme is basic unit front is 65 μ m, and top coat layer thickness is 40 μ m, and layer of varnish thickness is 10 μ m.
Described basic unit is galvanized sheet or aluminium plating zinc plate.
The polyurethane primer relating in the present invention, PVDF finish paint and PVDF varnish are application known materials for a long time in industry.Wherein, polyurethane primer is comprised of the polyurethane resin of isocyanato group containing, wear-and corrosion-resistant pigment, solvent, auxiliary agent, curing agent etc.; PVDF finish paint is mainly comprised of PVDF resin, acrylic resin, weather-proof pigment, solvent, auxiliary agent etc.As polyurethane primer is selected the polyurethane primer of selling outside Nippon Paint (China) Co., Ltd.; PVDF finish paint selects note forever to make the polyvinylidene fluoride resin finish paint of selling outside paint industry (Kunshan) Co., Ltd; PVDF varnish selects note forever to make the polyvinylidene fluoride resin varnish of selling outside paint industry (Kunshan) Co., Ltd.
Creativeness of the present invention is the combination that the positive thickness at all levels of the basic unit of design and material are selected, and makes it have stronger weatherability, wear resistence, protects the solid time limit more of a specified duration, protects the solid time limit and reaches more than 25 years.Product of the present invention is through salt spray test, and compared with common product, experiment parameter is increased to 260% left and right.
