Description
【Technical field】
The present invention relates to a kind of PET electron membranes UV hardening baths and its preparation method and application, belong to cold coating technology
Field.
【Background technology】
PET film also known as high temperature resistance polyester film.It has excellent physical property, chemical property and dimensional stability, thoroughly
Bright property, recuperability, can be widely used in magnetic recording, photosensitive material, electronics, electric insulation, industrial film, package decoration,
The fields such as screen protection, the protection of optical grade specular surface.
With PET film as base material, the application of many products can be derived, for example, PET conducting films, PET optical films etc., but
PET film anti-scratch, wearability in itself is poor, and this will be on post-production and using fatefulue influence is brought, in order to not influence PET
The application of film, the hardening coat for playing protective effect will arise at the historic moment.
UV hardening bath system quick solidifyings, film formation time is relatively fast, and the hardness of film is high, and anti-scratching wearproof is good, optical property
Good, volume contraction is small in solidification process, and without micromolecular compound residual, but the existing UV hardening baths in market, system viscosity is higher,
Film volume contraction is big, poor adhesive force, easily turns yellow, and UV monomers have residual.
【The content of the invention】
The invention aims to overcome the shortcomings of existing solvent-borne type UV cured coatings, there is provided a kind of preparation technology letter
Single, using convenient and swift, optics physical property is excellent after film forming, the PET electron membranes UV hardening baths of economic serviceability.
It is another object of the present invention in order to provide a kind of preparation method of above-mentioned UV hardening baths.
Third object of the present invention is to provide for a kind of application of above-mentioned UV hardening baths.
To achieve these goals, the present invention uses following technical scheme：
A kind of PET electron membranes UV hardening baths, including following mass percent component：
Wherein 1- hydroxy-cyciohexyls Benzophenone (184) and 2,4,6- trimethylbenzoy-diphenies phosphine oxide (TPO)
It is light trigger, butanone, propylene glycol monomethyl ether and 4-methyl-2 pentanone are organic solvent, the pure level of Optimization Analysis, function fat high
Adoption urethane acrylate resin is main body UV resins, and it has 9 degrees of functionality.
Further, a kind of PET electron membranes UV hardening baths, it is characterised in that including following mass percent component：
A kind of PET electron membranes preparation method of UV hardening baths, it is characterised in that comprise the following steps：
1) at room temperature by 1- hydroxy-cyciohexyl Benzophenones, 2,4,6- trimethylbenzoy-dipheny phosphine oxides are mixed in
In container；
2) in butanone, propylene glycol monomethyl ether and 4-methyl-2 pentanone being added into container, and stir；
3) function aliphatic polyurethane acrylic resin high is added in container, filtering is obtained final product after continuing to stir.
In preparation method of the present invention, step 2) and 3) in speed of agitator be 500r/min, mixing time 2.5h.
Wherein step 3) in filtering carry out pressure filtration with 10nm grades of filter bag.
When present invention preparation gained hardening bath is inverted in clean lighttight container, sealing preserve.
The present invention is mixed to prepare UV hardening baths, solubilizer by organic solvent that is the more commonly used, being easy to get by two one-step physicals
Preceding first to mix solid powder, it is to avoid to be stained with wall, second step solubilizer is conducive to preferably dissolved powders.When using, UV is hardened
In liquid gravure to PET electron membranes, the organic solvent in UV hardening baths is evaporated by infrared baking oven baking, shone under UV lamp
Penetrate, light trigger heterolytic fission is into free radical, and the crosslinking that acrylic acid unsaturated double-bond gains freedom between base, and then generation molecule is anti-
Should, form the excellent cured film of optics physical property.
Infrared baking oven is warming up to 90 DEG C when toasting, toast 2 minutes.
The present invention has the advantage that relative to prior art：
1st, inventive formulation applies organic solvent as diluent, can effectively reduce system viscosity, improves production and applies
Cloth adaptability, organic solvent has volatilized clean before UV solidifications are carried out, and is not involved in post-crosslinking, in solidification process, applies membrane volume and receives
Reduce；
2nd, used as matrix resin, after film-forming, hardness is high, and adhesive force is good, resistance to for the present invention UV resins of functional group high
Water is cooked, and light transmittance is high, and color inhibition is good, the low characteristic of mist degree.
3rd, the processing procedure route that the present invention is used is more brief, the repeatability that operation tool will be higher；
4th, using first infrared desolventizing, rear UV solidifications, after overcoming pure UV systems film-forming, volume contraction is big, attachment
Power is poor, the shortcomings of UV monomer residues.
【Specific embodiment】
With reference to specific embodiment, the invention will be further described：
The UV hardening bath each group distribution ratios of embodiment 1-5 are as shown in table 1：
Table 1：
The preparation method of embodiment 1-5 is：
1) at room temperature by 1- hydroxy-cyciohexyl Benzophenones, 2,4,6- trimethylbenzoy-dipheny phosphine oxides are mixed in
