Description
Technical field
The present invention relates to a kind of decorating film and preparation method thereof, relate more specifically to a kind of can add by the UV that shapes of deep processing
Hard decorating film and preparation method thereof.
Background technology
At present, general decorating film uses UV hardening process, is all directly at the surface printing UV stiffened coating of film, through UV
Lamp solidification can have very high rigidity, but film can not carry out when user uses degree of depth shaping process, such as deep-draw processing, otherwise
UV coating easily bursts, and the UV paint thickness being coated with can not be the thickest, and otherwise coating the most easily bursts.And if needing the degree of depth to become
The product that shape processes, can only first use decorating film to be compound to product surface, and film first carries out deep hole pinching, the most again with spraying or
The way of showering, coats UV hardening liquid, but uses spraying, and the masking liquid mode of spraying compares roller coat, and its efficiency is low, environmental pollution
Greatly, labor intensity is high.
Summary of the invention
It is an object of the invention to provide a kind of can the UV stiffened decorating film and preparation method thereof that shapes of the degree of depth, existing to solve
The problems referred to above that technology exists, after UV stiffened, film material case hardness is big, and film material case hardness is bigger, typically up to 3-5H,
Scratch resistance is higher, excellent mechanicalness and chemical-resistant.The present invention distinctive UV stiffened decorating film, user can be scribbling UV
The film adding hard conating is compound on material, carries out degree of depth forming technology simultaneously, and UV coating will not burst, product the most formed thereby
Very high rigidity is i.e. can reach again through UV lamp.
The technical solution used in the present invention is as follows:
A kind of can the degree of depth shape UV stiffened decorating film, its special UV stiffened coating used be special can be stamping
UV stiffened coating, the common UV coating in market when component design only UV coating be fabricated to single photograph UV lamp could solidify and
Immobilising formula, and inventor is in long-term summary of experience and experiment, creatively by UV Choice of Resin energy heat cure, UV
Lamp two kinds of functions of solidification, so corresponding used time the biggest help, first guarantee surface drying with thermosetting, then improve hardness with UV lamp, it is provided that
Work efficiency.
The preferably UV stiffened coating of this UV stiffened decorating film is urethane acrylate and the hydroxyl third of isocyanates
Olefin(e) acid resin, light trigger, solvent are made up of the mixing of following weight ratio:
The UV stiffened coating of this UV stiffened decorating film is grouped into by the one-tenth of following percentage by weight:
Urethane acrylate 10 90% containing isocyanates
The resin 10 90% of hydroxyl
Light trigger 1 10%
Solvent 0.1-50%
Levelling antifoam additives 1-5%.
Further, the UV stiffened coating of this UV stiffened decorating film is grouped into by the one-tenth of following percentage by weight:
Urethane acrylate 40 80% containing isocyanates
The resin 10 30% of hydroxyl
Light trigger 3 10%
Solvent 1-30%
Levelling antifoam additives 1-3%.
Further, the UV stiffened coating of this UV stiffened decorating film is grouped into by the one-tenth of following percentage by weight:
Urethane acrylate 50 70% containing isocyanates
The resin 10 20% of hydroxyl

Solvent 5-20%
Levelling antifoam additives 1%.
Light trigger can with 1173, the one or more of which such as TPO, 651 light triggers；
It is by UV light irradiation-cause specific acroleic acid polyurethane UV photopolymerization reaction that coating realizes base reason, wherein installs when painting
First realizing-NCO/-OH reaction in A factory, hydroxy acryl acid resin plays offer-OH key effect here, and containing isocyanates
Urethane acrylate play offer-NCO key effect, both reactions make coating realize surface drying rolling.
Afterwards when scribbling the material of this coating again through UV lamp, UV photopolymerization reaction will be realized, it is achieved solidification, show
High rigidity, here containing unsaturated bond in the urethane acrylate strand containing isocyanates, after irradiating UV lamp, draws at light
Sending out under agent initiation, the urethane acrylate containing isocyanates will realize UV solidification crosslinking, it is achieved high rigidity, gained coating is pliable and tough
Property big, adhesion of thin film is good, used coating process be coated with can with spraying, curtain coating or rolling method are constructed, and (spreading rate is
High 100g/m2).
Preferably, a kind of can the degree of depth shape UV stiffened decorating film, its processing technology is:
A () first makes decorating film,
(b) again on special UV stiffened paint spraying to decorating film,
(c) rolling after fully drying again,
D () is compound to film on object, and form process,
E () eventually passes the solidification of UV lamp, so far described stiffened decorating film i.e. completes.
Wherein, after step (c), it is possible to declaration production completes, and step (d) and (e) are left to other work
Factory or client carry out UV voluntarily and irradiate stiffened, because (d) (e) step does not possess the biggest difficulty, separate this step and can reduce former
Beginning factory technics step, reduces the input of client, need not purchase spraying equipment so that produce more flexible.So step completes
After, the surface of this decorating film is up to high rigidity, typically up to 3-5H, it is achieved UV stiffened function.The speed of UV solidification depends on
Co-reactant used and the type of added light trigger and quantity.Preferably, the special decorating film of combined forming process passes through
PUR or hot melt film medium, be adhered on material, and some situation meeting high temperature, pull-shaped for film change, pastes thickly product wrapping, some
Situation can carry out cold stamping shaping the material being combined, this series of process all referring to combined forming process, this kind of technique bag
Include TOM, IMD, OMD, IML, IMR laminating adhesive etc..
Preferably, a kind of can the degree of depth shape UV stiffened decorating film, the UV stiffened coating wherein shaped is coated with in this stiffened
The most surface of decorating film, this stiffened decorating film is UV base membrane layer, printing layer, electrodeposited coating, glue layer, bonding Jie the most respectively
Matter layer, wherein selected base membrane layer are preferably pet layer, and actual application can also is that different film layer.Bond medium layer can be
Polymeric membrane or hot melt adhesive film, play and other material bonding effect.This kind of decorating film is a kind of multiple structure, has various
Property.
Preferably, this special UV coating can also be applied on release transfer film, special coating will be coated on from
On type layer, in technique, the manufacture method for mould release membrance is first its release layer surface to be coated with special UV coating and make surface reach
To surface drying, repasting adhesive linkage, then carry out UV solidification, under room temperature or mandatory condition ,-NCO/-OH carries out supplementing reaction, afterwards
Covered with protective film on release layer, wherein protecting film is preferably the film of PET or other material.The paint film being achieved in that has well
Adhesive force and excellent mechanicalness and chemical-resistant.
Wherein, described acroleic acid polyurethane is the paint vehicle formed with senior acrylic resin, pigment, auxiliary agent and solvent etc.
For components, with the two-component air-dry coating that aliphatic isocyanates is another component.Weather resistance is excellent；Paint film is ornamental
Energy good (plentiful light, hardness are high)；Chemical resistance is good；Guarantor's light, unfading are excellent；High adhesion force, good mechanicalness
Energy.
Light trigger, also known as photosensitizer or light curing agent, is that a class can be in ultraviolet region (250～420nm) or visible region
(400～800nm) absorb the energy of certain wavelength, produce free radical, cation etc., thus the solidification of trigger monomer polymerization crosslinking
Compound.
