Description
Technical field
The invention belongs to the steel plate is the technical field of composite materials of substrate, relates in particular to a kind of electrical equipment that satisfies national standard and European Union's standard steel plate overlay film matrix material.
Background technology
Coloured coating clad steel plate or the material that has just generally adopted for the shell of electronics such as electrical equipment with PSS (Prepainted Steel Sheet), structural sheeting and architectural decoration panel also adopt this coloured coating clad steel plate or just band in a large number.At present general composite molding color steel structure is polyester/polyvinyl chloride/tackiness agent/steel plate, and this matrix material can satisfy the high strength cupping experiment of regulation among the GB/T12754-1991 " color-painted steel strip and just band " and various weathering resistance, the requirement of antifatigue experiment test.
Producing this kind color-painted steel strip is Henkel KGaA (HENKEL) group company and Sony (SONY) chemical company with the manufacturer of compoiste adhering functional materials.Representative products wherein is the industrial binding agent SC-457 of Sony chemical company exploitation, and this binding agent is in the same place polyvinyl chloride film layer and base plate bonding with the embrane method of single liquid sintered type, and adhesive thickness is greater than 5 μ m.
On February 13rd, 2003, European Union has announced " discarded electric and electronic utensil decree " and " special harmful substance that restriction uses electric and electronic partly to contain " (WEEE; ROSH), content to each heavy metal species in the Industrial products has strict demand, this just required before in January, 2006, China's domestic color steel sheet processing and use producer and must adopt that to contain heavy metal up to standard or do not contain the polyvinyl chloride film of heavy metal, perhaps produce and adopt the color steel sheet that do not contain polyvinyl chloride film and just band with for export.Added a spot of heavy metal additive and the polyvinyl chloride film that uses in color steel sheet and the firm belt composite is unavoidable in process of production, the binding agent of existing Henkel KGaA and Sony can not satisfy China's national standard and the WEEE ﹠amp of European Union to steel plate and polyester film after directly compound; In the ROSH standard about the requirement of cupping experiment and various shearing resistance and other performance tests.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can satisfy China's national standard and the WEEE ﹠amp of European Union; ROSH standard, thin thickness, the direct composite coloured coated steel sheet of lightweight polyester film reach band just, and a kind of satisfy composite demand, strong being used for this color-painted steel strip and just being with the compound tackiness agent of cohesive force also are provided.
The technical solution used in the present invention is as follows:
A kind of color-painted steel strip matrix material, with the coated steel sheet is substrate, it is characterized in that composite polyester film on the coat side of coated steel sheet, the two is the polyurethane adhesive layer, the thickness of coated steel sheet is 0.1～2.5mm, the thickness of polyester film is 10～50 μ m, and the thickness of adhesive layer is 3～30 μ m.
Described coated steel sheet is cold-rolled steel sheet, hot-dip galvanizing sheet steel, hot-dip aluminizing zincium steel plate or the electrogalvanizing steel plate with polyester, silicon modified polyesters, poly-partially difluoroethylene or plastisol coating.
The coating state of described coated steel sheet is coat, cotton ginning layer or printed layer.
Described polyester film comprises normal transparent polyester film, delustring polyester film, printed polyester film, pearly-lustre polyester film and MULTILAYER COMPOSITE polyester film.
The skin of described polyester film also is pasted with cellothene, and the thickness of polyethylene film is 10～100 μ m.
This polyurethane adhesive is the polyurethane adhesive that the copolymerization of acrylic acid or the like modify and graft obtains, and its raw material weight per-cent consists of:
Acrylic monomer:
Rocryl 410 1～15%
Tackifier:
Para-tertiary butyl phenol-formaldehyde resin 1～15%
Bisphenol A epoxide resin 1～15%
Novolac epoxy 1～15%
Softening agent:
Dioctyl phthalate (DOP) 1～15%
Solvent:
Ethylene glycol monomethyl ether 1～30%
Other:
'-diphenylmethane diisocyanate 1～15%
TriMethylolPropane(TMP) 1～15%
The number-average molecular weight of described polyester polyol is 20,000～2,000,000.
The preparation method of the tackiness agent that color-painted steel strip matrix material provided by the invention uses is as follows: get the pure and mild TriMethylolPropane(TMP) of quantitative polyester polyols in proportion and dissolve in toluene solvant, add '-diphenylmethane diisocyanate and tolylene diisocyanate and under 60～100 ℃ of conditions, carry out modification, the mass percentage content of the group of detection-NCO is in 1～10% scope, add acrylic monomer again, under 60～100 ℃ of conditions, add then
It is even that the ethylene glycol monomethyl ether solvent reaction 2～10 hours that contains peroxide initiator, cooling add softening agent, tackifier and other solvent, promptly obtains this polyurethane adhesive.
Described peroxide initiator is the new certain herbaceous plants with big flowers acid of a benzoyl peroxide and peroxidation isopropyl benzene ester.
The present invention's color-painted steel strip is a substrate, and polyester film is done outer, as intermediate adhesive layer, forms composite structure with the transparent polyurethane tackiness agent, realizes the rational Match of trilaminate material thickness by each layer structure optimization design.The diaphragm that this polyurethane adhesive forms and the shearing resistance of polyester film and substrate steel sheet can reach more than the 30Mpa.That the coating color of substrate steel sheet has is orange, milk is yellow, deep sky blue, sea blue, bright red, brick red, ivory white, ceramic cobalt blue or the like, the coating state of substrates coatings to the cohesive force of polyurethane adhesive without any influence.
Polyester film surface for fear of color-painted steel strip matrix material in the following process process is damaged, and also pastes the cellothene that thickness is 10～100 μ m at the skin of polyester film.
In the raw material of the polyurethane adhesive of acrylic acid or the like modify and graft used in the present invention, number-average molecular weight is 20,000～2,000,000 polyester polyol is with hexanodioic acid, m-phthalic acid, terephthalic acid, 1,4-butyleneglycol, ethylene glycol and 1,2-propylene glycol are that raw material adopts the common process preparation.
Beneficial effect of the present invention is that this color-painted steel strip matrix material is polyester film/polyurethane adhesive/color-painted steel strip structure, has excellent mechanical property, can satisfy China's national standard and the WEEE ﹠amp of European Union simultaneously; The ROSH standard, substitute existing exported product, and compare in light weight with currently available products, thin thickness, the employed polyurethane adhesive of this color-painted steel strip matrix material has extremely strong cohesive force to two adhesive faces, the shearing resistance height of bonding rete is compared the 30-50% that can reduce cost with the import adhesive special with performance, can also obviously improve the surface aesthetic degree of color-painted steel strip matrix material.
