The beneficial effects of the invention are as follows：This case is for the not high defect of tradition PVDF film coated plates adhesion strength, to being used
Adhesive improved；Adhesive is aided with multiple polymers, organic molecule and strontium chloride based on epoxy resin,
The balance of cohesive force between adhesive and pvdf membrane and steel plate is taken into account, synthesis improves adhesive and pvdf membrane and steel plate are glued
Knotting strength, has been effectively ensured the structural stability of film coated plate, so as to increase the service life of film coated plate.
Embodiment
With reference to embodiment, the present invention is described in further detail, to make those skilled in the art with reference to specification
Word can be implemented according to this.
This case proposes the high life of an embodiment high anti-corrosion PVDF film coated plates, and it is sequentially provided with poly- inclined difluoro second from top to bottom
Alkene film layer, adhesive layer, steel plate layer, adhesive layer and PVDF membrane layer；
Wherein, adhesive layer includes the material of following parts by weight：
Propine-hydroxyethylacrylate copolymer is random copolymer, and its synthetic method is identical with the synthetic method of poly- propine,
Propine monomer and hydroxyethyl acrylate monomers need to only be mixed by predetermined ratio, then carry out random copolymerization.Propine-acrylic acid hydroxyl
Methacrylate copolymers are found after being combined with epoxy resin, and adhesive can be improved on the premise of system stickiness is not increased
Toughness and bond strength.Makrolon and can cooperateing with after being combined to methylbenzeneacetamide improves adhesive at low ambient temperatures anti-
Bursting by freezing performance.Hexahydropyridine can increase the adhesion strength of adhesive at high temperature, to ensure that adhesive layer is not soft at high temperature
Change, do not fall off.Strontium chloride is used for the shock resistance for improving adhesive layer, meanwhile, it can also improve adhesive each component knot
The tightness degree of conjunction, so as to the hardening time of proper extension adhesive, to obtain more preferably stable and firm cohesive force.
As another embodiment of this case, wherein, in propine-hydroxyethylacrylate copolymer, propine content is preferably 15~
16wt%.In order to further be optimized to adhesive, it is necessary to in propine-hydroxyethylacrylate copolymer, the content of propine
It is defined, if deviateing preferred number range, the adhesion strength for causing adhesive is deviateed into optimal value.
As the another embodiment of this case, wherein, the number-average molecular weight of propine-hydroxyethylacrylate copolymer for 3000~
3200g/mol.In order to further be optimized to adhesive, it is also desirable to which the number of propine-hydroxyethylacrylate copolymer is divided equally
Son amount is defined, if deviateing preferred number range, and the adhesion strength for causing adhesive is deviateed into optimal value.
As the another embodiment of this case, wherein, the number-average molecular weight of epoxy resin is 4200~4300g/mol.In order to enter
One step is optimized to adhesive, it is necessary to the number-average molecular weight to epoxy resin is defined, if deviateing preferred number range,
The adhesion strength for causing adhesive is deviateed into optimal value.
As the another embodiment of this case, wherein, the number-average molecular weight of makrolon is 2200~2300g/mol.In order to enter
One step is optimized to adhesive, it is necessary to the number-average molecular weight to makrolon is defined, if deviateing preferred number range,
The adhesion strength for causing adhesive is deviateed into optimal value.
As the another embodiment of this case, wherein, adhesive layer also includes the methyl caprylate of 0.2~0.3 parts by weight.Sad first
Ester is a kind of viscosity- increasing agent, and it can assist the formula of original adhesive to produce stronger adhesion strength.But this additive
Consumption must be limited, its addition scope is extremely limited, slightly offset from preferred addition scope, and the enhancing of viscosity will be caused to make
Even failed with weakening.Research also found that ethyl caprilate, butyl caprylate, the methyl heptanoate similar with methyl caprylate structure etc. are
There is no improvement effect.
As the another embodiment of this case, wherein, adhesive layer also includes the isopropyl acetoacetic ester of 0.2~0.3 parts by weight.Isopropyl
Acetoacetic ester is the synergist of methyl caprylate, and synergy, the adhesion strength of common enhancing adhesive can be produced with methyl caprylate.And
On the premise of no methyl caprylate, isopropyl acetoacetic ester can not produce positive role to improving adhesion strength in itself.Therefore, it is different
Ethyl propionate and its addition should be limited in particular range with methyl caprylate.Research also found, with isopropyl acetoacetic ester
The similar isopropyl acid methyl esters of structure, isopropyl acid butyl ester, n Propanoic acid ethyl ester etc. are without improvement effect.
As the another embodiment of this case, wherein, adhesive layer also includes 2, the 6- di-tert-butyls of 0.2~0.3 parts by weight
Phenol.2,6- DI-tert-butylphenol compounds are a kind of anti-hardening agents, for preventing adhesive is hardened after long-term use from coming off.But it is this anti-
The consumption of curing agent must very with caution, and deviateing preferred scope will have a negative impact on the contrary.Research also found, with the uncles of 2,6- bis-
Butylphenol structure similar 2,6- xylenols, 2,6-Bis(1-methylethyl)phenol, ortho-methyl phenol, o-tert-butylphenol etc. are
There is no improvement effect.
The material of this case steel plate layer is unrestricted, as general steel plate.The specification of pvdf membrane is also unrestricted, PVDF
The thickness of film, steel plate and adhesive layer is also unrestricted, because research is found, the selection of thickness does not have shadow to the performance of film coated plate
Ring.Therefore, each thickness degree of film coated plate can carry out free setting according to actual needs.
