TABLE 1
Figure BDA0001692298470000161
Figure BDA0001692298470000171
Note:
the total light transmittance and the haze of the plastic are measured according to the standard of JIS K7105-1981, namely a method for measuring the optical performance of the plastic.
The pencil hardness was measured in accordance with JIS K5400-1990 "measurement of adhesion of powder coating film".
HC adhesion was tested according to GB 1720-1979 "paint film adhesion test", where 100/100 stands for no release at all and 90/100 stands for 10% release.
Testing the wear resistance of the film according to HG/T4303-2012 & lt method for measuring wear resistance of surface hardening polyester film, and adopting 0000# steel wool and 1000gf/cm2And (3) loading, namely judging the wear-resisting effect of the film by detecting the limit of the wear-resisting times of the surface of the film without scratches, wherein the higher the wear-resisting times is, the better the effect is.
According to GB/T30693-2014 plastic film andaccording to the standard of the measurement of the water contact angle, the water contact angle of the surface of the film is tested, and the higher the water contact angle is, the better the hydrophobicity is, and the better the anti-fingerprint effect is. The fingerprint residue test method is as follows: leaving a fingerprint on the film at 200gf/cm2And (3) loading, binding the dust-free cloth on the abrasion-resistant instrument, wiping the membrane back and forth for 5 times, and observing the residual condition of the fingerprints.
Judging the fragrance of the material according to the standard of GB/T14454.2-2008 'perfume fragrance evaluation method', wherein O represents obvious fragrance, □ represents slight fragrance, and X represents no fragrance.
In the table, the formula of the repairable coating liquid refers to the weight ratio of the perfume, the resin and the solvent, and the formula of the anti-fingerprint coating liquid refers to the weight ratio of the resin, the curing agent and the solvent.
The data in the table show that the invention can form a cured coating with adhesiveness, light transmittance, haze, hardness, fingerprint resistance and fragrance on the surface of a PET substrate. The material has the advantages that: not only ensures the excellent fingerprint-proof function of the material, but also endows the material with certain fragrance which can last for more than two months. FIG. 2 shows the flavor retention tendency of the hardened film of example 1 of the present invention, and the aroma concentration was measured by GC-MS.
In addition, the fragrance concentration of the fragrant fingerprint-resistant hardened film can be adjusted by the addition amount of the fragrance and the pore-forming agent, and the fragrance of the material is slight when the addition amount of the fragrance is too small, but the fingerprint-resistant performance of the material is reduced when the addition amount of the fragrance is too large. The addition of the pore-forming agent can reduce the wear resistance of the material, but the influence is not too great in a certain range, and if the pore-forming agent exceeds the optimal range, the wear resistance is greatly reduced, and the adhesion is reduced.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
