As shown in Figure 3, tack coat 21 among the present invention adopts the ultra-violet curing adhesive, be spun on the flexible substrate, tack coat 22 among the present invention adopts the ultra-violet curing adhesive, be spun on first tack coat 21, but first tack coat 21 is identical or different with the ultra-violet curing adhesive component that second tack coat 22 uses, and concentration is identical or different, and the adhesive layer thickness of formation is identical or different.
Each composition is described as follows among the present invention:
Unsaturated polyester resin: unsaturated polyester (UP) is to mix the linear polyesters that reacts and make with fractional saturation binary acid (or acid anhydrides) and dihydroxylic alcohols by undersaturated binary acid (or acid anhydrides) under action of evocating.In its molecular structure, there is undersaturated vinyl monomer to exist, if with active vinyl monomer and the undersaturated vinyl monomer copolymerization of this class, crosslinking curing and become three-dimensional-structure then.In general, the adhesive that makes by this resin since in the solidification process volume contraction bigger, the internal stress of gluded joint is very big.Micro-crack occurs easily and cause splicing power to diminish in the inside of glue-line; Simultaneously,, meet acid, the easy hydrolysis of alkali, thereby resistance to medium and resistance to water are relatively poor, easy deformation under the how wet environment of high temperature owing to contain ester bond in the macromolecular chain; In addition, its curing rate is slower, therefore, shows relatively poor combination property, so mostly use as non-structure glue.By reducing unsatisfied chemical bond content, adopt the low monomer of polymerization shrinkage, adding means such as inorganic filler and thermal plastic high polymer, can improve its overall performance.
Acrylic resin: this resin system curing rate is fast, studies morely at present.
Monomer (styrene and derivative thereof etc.) usually and resin be used, one side is as diluent, the viscosity that glue is had be convenient to construct; Have reactivity on the other hand again, solidify the laggard resin network of going into, the final performance of solidfied material is had certain improvement.The early stage monomer that uses is styrene and derivative thereof, and this class diluent crosslinking rate is slow, volatility is big and poisonous, poor heat resistance.Now, simple function group or polyfunctional group (methyl) acrylate of adopting more, as methyl methacrylate, ethyl acrylate, acrylic acid propylene glycol ester, n-butyl acrylate etc., the relatively poor problem of adhesive ubiquity thermal endurance of these ester preparations, and also there is the big defective of volatility in the lower ester of some molecular weight.If introduce aromatic rings in the molecular structure, then can improve the intensity and the resistance to water of glue, prolong the storage period of glue.Requirement to monomer mainly is: the respond of low viscosity, highly diluted effect and height, it is little also will to take into account volatility, toxicity and peculiar smell simultaneously, good etc. to the compatibility of resin.In order to regulate various performance parameters, often adopt mix monomer, mix monomer is as follows: free radical activity diluent and cation activity diluent.
The free radical activity diluent is divided into exploitation first generation acrylic acid polyfunctional monomer, the second generation acrylic acid polyfunctional monomer of recent development and more excellent third generation acrylic monomers early.
The simple function reactive diluent has: styrene, N-vinyl pyrrolidone, Isooctyl acrylate monomer, hydroxy-ethyl acrylate and isobornyl acrylate, methacrylate phosphate and isobornyl methacrylate, latter two is the good toughness reinforcing monomer of plasticising.

Second generation acrylic acid polyfunctional monomer mainly is to introduce ethyoxyl or propoxyl group in molecule, has overcome the big shortcoming of excitant, also should have higher activity and state of cure.As ethoxylation trihydroxy methyl propane triol triacrylate [TMP (EO) TMA], propoxylation trihydroxy methyl propane triol triacrylate [TMP (PO) TMA], propoxylation glycerol triacrylate [G (PO) TA].Third generation acrylic monomers is mainly the acrylate that contains methoxyl group, preferably resolves the contradiction of high curing rate and shrinkage, low state of cure.This class material has 1,6-hexylene glycol methoxyl group mono acrylic ester (HDOMEMA), ethoxylation neopentyl glycol methoxyl group mono acrylic ester [TMP (PO) MEDA].After introducing alkoxyl in the molecule, can reduce the viscosity of monomer, reduce the excitant of monomer simultaneously.
The introducing of alkoxyl is also improved a lot to the compatibility of diluent monomer, and vinyltriethoxysilane (A15I), gamma-methyl allyl acyloxypropyl trimethoxysilane (A174) can be used as monomer.
Cruel in various active epoxy diluent resins and various cyclic ethers, the ring, vinyl ether monomers etc. can be as the diluent of cation photocuring resin.Therein ethylene pyridyl ethers compound and oligomer curing rate are fast, modest viscosity, tasteless, nontoxic, can be used with epoxy resin.Vinyl ether monomers has: 1,2,3-propanetriol-diglycidyl-ether (EPON-812), triethylene glycol divinyl ether (DVE-3), 1,4-butanediol vinyl ethers (HBVE), cyclohexyl vinyl ether (CHVE), perfluoro methyl vinyl ether (PMVE), the perfluor n-propyl vinyl ether, IVE, hydroxy butyl vinyl ether, vinyl ethyl ether, ethyl vinyl ether, the ethyl vinyl ether propylene, ethylene glycol monoallyl ether, hydroxy butyl vinyl ether, butyl vinyl ether, chlorotrifluoroethylene (CTFE), triethylene glycol divinyl ether, methoxy ethylene, the vinyl n-butyl ether, dodecyl vinyl (DDVE), cyclohexyl vinyl ether, tribenzyl-benzene phenol polyethenoxy base ether, tetrafluoroethene-perfluoro propyl vinyl ether, tetrafluoroethene-perfluoro propyl vinyl ether, tert-Butyl vinyl ether:

Light trigger: in the ultraviolet photo-curing cementing agent, often need to add Photoactive compounds, with the carrying out of initiation or accelerated reaction.Difference by its mechanism of action can be divided into light trigger and sensitising agent.Difference is that light trigger when the reaction beginning, absorbs the luminous energy of suitable wavelength and intensity, photophysical process takes place reach its a certain excitation state, if this excited energy greater than the breaking bonds energy needed, then produces free radical polymerization; And sensitiser absorption luminous energy is to its a certain excitation state, just with energy in molecule or intermolecular the transfer, produce free radical polymerization by another molecule that obtains energy.Compare with light trigger, sensitising agent itself does not consume or changes structure, and it can be regarded as photochemically reactive catalyst.Its mechanism of action roughly has three kinds: the one, and the energy transfer mechanism, the 2nd, take hydrogen mechanism by force, the 3rd, through generating the photosensitive mechanism that electric charge shifts.The light trigger of having developed with practical value has styrax and derivative and acetophenone derivative, and sensitising agent has benzophenone, thia anthraquinone and Michler's keton.The stability of various initators, yellowing resistance, trigger rate have nothing in common with each other, and in different resin systems, efficiency of initiation is also different, should rationally select for use according to the needs of different occasions.As cyanacrylate and C (CH 2OCCH 2CH 2SH) system, use benzoin methyl ether, benzoin ethyl ether respectively, benzoin isopropyl ether causes, be respectively 18s, 20s and 25s curing time, and when causing with benzophenone, only be 15s curing time, and simultaneously the light transmittance of solidfied material also can difference be bigger owing to the wavelength difference, and this will rationally select for use according to actual conditions.
The effect of light trigger is after it absorbs the ultraviolet light energy, produces free radical through decomposing, thus the unsaturated bond polymerization in the initiator system, and crosslinking curing becomes an integral body.Radical photoinitiator commonly used has the cracking type and puies forward Hydrogen two big classes.
Crack type photoinitiator: crack type photoinitiator mainly contains benzoin ethers (styrax ethers), benzil ketals and acetophenone etc.Crack type photoinitiator is chapped after absorbing ultraviolet light, produces two free radicals, and free radical causes the unsaturated group polymerization.Benzoin ethers (styrax ethers) comprising: styrax (Benzoin), benzoin methyl ether, benzoin ethyl ether (Benzoin ethyl ether), benzoin isobutyl ether (Benzoin butyl ether), styrax lose (Benzoin oxime), benzoin isopropyl ether; Acylphosphine oxide comprises: 2; 4; 6 trimethylbenzene formyl diphenyl phosphine oxides (TPO) and (2; 4; 6-trimethylbenzene formyl) phenyl phosphine oxide [BAPO phenyl bis (2; 4; 6-trimethyl benzoyl) phosphine oxide]; two (2,4, the 6-trimethylbenzoyl) phosphine oxides (819) of phenyl; tetramethylpiperidone oxide (TMPO); triethyl phosphate (TEPO); they are more satisfactory light triggers; have very high light-initiated activity, the long wave near ultraviolet ray is had absorption, be applicable to the situation that whitewash and film are thicker; and have good stability, can variable color or fade.
Carry the Hydrogen initator: carry the Hydrogen initator and mainly contain benzophenone and thioxanthones etc.Wherein at 380-420nm, and absorbability and hydrogen-taking capacity are strong, have higher efficiency of initiation at the maximum absorption wavelength in black light district for thioxanthone photoinitiator.Carrying the Hydrogen initator must have hydrogen donor as collaborative composition, otherwise efficiency of initiation is too low, so that can not be put to use.Triplet state carbonyl free radical than more likely extracting hydrogen on the secondary carbon or on the methyl, is connected on hydrogen on the hetero-atoms such as oxygen or nitrogen than the easier extraction of the hydrogen on the carbon atom from the tertiary carbon of hydrogen donor molecule.This class hydrogen donor has amine, hydramine (triethanolamine, methyl diethanolamine, triisopropanolamine etc.), mercaptan, N, the N-diethyl-and to the dimethylamino benzamide.
The benzophenone light initiation system, benzophenone need be with alcohol, ether or amine and with just making vinyl monomer carry out photopolymerization.Mainly comprise: benzophenone, the thia anthraquinone, Michler's keton, dimethoxy benzene acetophenone (DMPA), alpha-hydroxy-2,2 dimethyl acetophenones (1173), Alpha-hydroxy cyclohexyl-phenyl ketone (184), α-amine alkyl phenones, 2-methyl isophthalic acid (4-first coloured glaze base phenyl)-2-morpholinyl acetone (MMMP), 2 ' 2-dibenzamidodiphenyl disulfide (DBMD), (4-dimethylamino phenyl)-(1-piperidyl)-ketone, isopropyl thioxanthone (ITX), (4-dimethylamino phenyl)-(4-morpholinyl)-ketone, 2-hydroxy-2-methyl-1-phenyl-1-phenyl-1-acetone, two phenoxy group benzophenone, hydroxy-2-methyl phenyl-propane-1-ketone.And mixed system, as eliminating oxygen in the glued membrane to the benzophenone of the inhibition of Raolical polymerizable and the initiator system that cooperates of uncle's ammonia; Michler's keton and benzophenone are used, and can obtain more cheap and effectively initiator system.
