Description
Technical field
Present invention is directed to a kind of plastics film and be applied to the making method of in-mold decoration, refer to a kind of making method that has the plastics film of plasticity-and be applied to in-mold decoration especially.
Background technology
In conventional art, adopt method of radiating (for example ultraviolet ray, ir radiation or electron beam irradiation) that the coating system that contains activity double key is cured, widely known and accomplished technically.This is one of the fastest curing in coating technology, yet the sticking power deficiency but is a common problem.But the coating material solidified curing of electromagnetic radiation need depend on suitable radiation dose.Relatively poor or do not have the zone of illumination in illumination, can cause solidifying variation or not crosslinked significantly.
The tamanori that is the basis with isocyanic ester and polyvalent alcohol is fit to make high-quality coating very much.Desired various coating properties like sticking power, elasticity, chemical resistant properties, weathering resistance or scratch-resistant etc., can be adjusted in very wide scope through changing raw material.
Above-mentioned two mutually independently consolidated structures be attached in the bonding system, can make their advantages.This being called,, the system of " two curing " system was known.For example,, put down in writing by the radiation-hardenable reactive thinner applicable cases of the coating system of forming like propenoate, polyvalent alcohol and isocyanic ester in 793 in U.S. Pat 4,342.The problem that this individual system exists is: in the area that does not have illumination; The reactive thinner of this radiation-hardenable stays becoming softening agent; And softening agent can produce detrimentally affect to the character of film thus, perhaps even can leave with divided thin film, thereby has caused undesirable physical influence appearance.
Be known that equally the radiation-hardenable group is connected to " two curing " tamanori on the POLYMETHYLENE POLYPHENYLISOCYANATE with the chemical bond mode, can avoid the appearance of the problems referred to above.For example, European patent application EP-A0928800 has put down in writing the applicable cases of the functionalized urethane acrylate that contains isocyanurate group of NCO-as a kind of " two curing " coating system.In order to use these coating compounds easily, need reach enough low viscosity, so different organic solvents has been used in convention.
Because the requirement of ecological and cost if modern coating system must with an organic solvent also will reduce use as much as possible, therefore in order to reduce viscosity, then must be used the coating resin of low-viscosity.Special in 0682012 record of European patent EP-A, the POLYMETHYLENE POLYPHENYLISOCYANATE that has urea carbamate structure for this purpose comes out already.
Moreover can be applicable to in-mold decoration through above-mentioned traditional produced plastics film of mode, and the making flow process of this plastics film approximately is: step (1) coating → step (2) earlier reshapes → step (3) final curing.Then; Because above-mentioned steps (2) and step (3) might be implemented two different locations; So when half-finished plastics film is transported to another when ground from a ground, need adds covering especially and produce curing to protect half-finished plastics film to avoid to receive the irradiation of light.Edge is, can the improving of the above-mentioned disappearance of inventor's thoughts concentratedly observed and study it, and cooperates the utilization of scientific principle, and proposes a kind of reasonable in design and effectively improve the present invention of above-mentioned disappearance.

See also shown in the table two the different experiments appearance that above-mentioned sample 1 is mixed to sample 7
Originally descend the test of 7 kinds of different mass characteristics of example, with the experimental data that obtains being correlated with.
<table two >
Hold the experimental data of above-mentioned table one and table two, obtain following results:
1, can know by the comparison of sample 1 to sample 3; When the weight percent of thermosetting resin reduces gradually, the weight percent of photo-hardening multiple functional radical oligomer increases gradually, the weight percent of linking agent reduces gradually and the weight percent of initiator when increasing gradually; The resulting data of then hardness test (Hardness) have the trend (from H to 3H) of rising; The resulting data of Steel Wool abrasion resistance test (Δ Haze) have a declining tendency (from 12.58 to 9.12); The resulting data of RCA abrasion resistance test (Cycles) have the trend (from 20cycles to 50cycles) of rising; Formability test (Forming ability) resulting data have a declining tendency (from splendid to general), and extensibility test (Elongation) resulting data have a declining tendency (from 1.5 times to 1.1 times).
2, can know by the comparison of sample 2, sample 4 and sample 5, when the weight percent that blendes together material when organic inorganic nano increases (from 0% to 10%), resulting data of Steel Wool abrasion resistance test (Δ Haze) have a declining tendency (from 10.75 to 0.19) then.Therefore, the increase organic-inorganic nano blendes together material weight per-cent to 5% can effectively increase the Steel Wool abrasion performance.
3, can know by the comparison of sample 4 and sample 6; When the weight percent of ultraviolet light polymerization multiple functional radical reaction monomers increases (from 0% to 10%); Then the resulting data of RCA abrasion resistance test (Cycles) have significantly the trend (from 30cycles to 100cycles) that rises, and the resulting data of Steel Wool abrasion resistance test (Δ Haze) then have a declining tendency (from 0.22 to 0.05).Therefore, the weight percent that increases ultraviolet light polymerization multiple functional radical reaction monomers can significantly increase the RCA abrasion performance, but then can't effectively increase for the Steel Wool abrasion performance.
4, can know by the comparison of sample 6 and sample 7; When sample 7 adds inorganic nano-particle; For Steel Wool abrasion performance relatively poor (from 0.05 to 0.19), and the resulting data of optical characteristic test (Haze) have significantly the trend (from 0.17 to 1.97) that rises, and cause the not good situation of transparency.Therefore, add inorganic nano-particle and will influence optical characteristics (transparency).Therefore most preferred embodiment of the present invention is a sample 6, has high firmness (2H), splendid Steel Wool wear resistant and RCA wear resistant and plastic extensibility simultaneously concurrently.
See also shown in first figure and second figure, the present invention provides a kind of plastic film applications with plasticity-in the making method of in-mold decoration (In-Mould Decoration), and it comprises the following steps:
