In addition,, in description of the present utility model, except as otherwise noted, the implication of " a plurality of " is two or more.
Below with reference to Fig. 1 and Fig. 2, describe according to the mobile terminal shell 100 of the utility model embodiment, wherein this mobile terminal shell 100 can be the housing of phone housing or other electronic products.
As depicted in figs. 1 and 2, mobile terminal shell 100 according to the utility model embodiment, comprising: sheet material 1, patterned layer 2 and background layer 3, wherein, patterned layer 2 is located on the part lower surface of sheet material 1, and patterned layer 2 is for being provided with a plurality of metal films 20 in ink layer and patterned layer 2.That is to say, the part lower surface of sheet material 1 is provided with patterned layer 2, and all the other lower surfaces of sheet material 1 are not provided with patterned layer 2.In concrete example of the present utility model, metal film 20 is aluminium film, and the thickness of sheet material 1 is 0.3-1.0mm, and the thickness of patterned layer 2 is 15-20 μ m, and the thickness of background layer 3 is 15-30 micron.
Particularly, this patterned layer 2 is to form with the ink printing of the metal film 20 that contains ultra-fine layer structure.Wherein metal film 20 is, under vacuum condition, evaporation of metal is deposited as to membrane structure, then be crushed to certain particle diameter, in concrete example of the present utility model, thicknesses of layers is 20-100 nanometer, be of a size of 4-8 micron, metal film 20 after pulverizing be uniformly distributed and the parallel resin that spreads over ink in, a plurality of metal films 20 are uniformly distributed and parallel spreading in patterned layer 2.The weight of metal film 20 accounts for the 20-60% of the total weight of patterned layer 2.It should be noted that, the total weight of patterned layer 2 refers to the weight sum of ink layer and metal film 20.Wherein require the metal film 20 in the ink layer after printing parallelly to sprawl, as shown in the arrow in Fig. 2, incident optical energy reflects away to greatest extent, obtains the appearance effect of superbright.
Background layer 3 is located on all the other lower surfaces of sheet material 1 and the lower surface of patterned layer 2.Wherein background layer 3 provides background color for whole product, and protects patterned layer 2 not to be damaged.
According to the mobile terminal shell 100 of the utility model embodiment, patterned layer 2 adopts the ink printing that contains metal film 20, after printing, 20 pairs of incident lights of the metal film of stratiform have stronger reflection, thereby make the patterned layer 2 of mobile terminal shell 100 have the appearance effect of superbright.And because patterned layer 2 is between sheet material 1 and background layer 3, guarantee that patterned layer 2 in use can not be scratched or wear and tear, durable in use, this mobile terminal shell 100 is simple in structure simultaneously, is convenient to machine-shaping.
In examples more of the present utility model, background layer 3 is ink layer, and now require has stable color performance in printing process, can not corrode dried patterned layer 2.
As shown in Figure 1, in specific embodiment of the utility model, sheet material 1 comprises: Merlon (PC) layer and add hard formation 11, add on the upper surface that hard formation 11 is positioned at layer of polycarbonate 10, the hardness that adds hard formation 11 is greater than the hardness of layer of polycarbonate 10, and patterned layer 2 is located on the lower surface of layer of polycarbonate 10.Thereby make sheet material 1 there is good physical and chemical performance, can improve the hardness of sheet material 1.Particularly, add hard formation 11 for polyorganosiloxane resin layer.Wherein, between patterned layer 2 and layer of polycarbonate 10, to there is good adhesion.
Further, mobile terminal shell 100 also comprises transition resin bed 12, and transition resin bed 12 is at layer of polycarbonate 10 and add between hard formation 11, and particularly, transition resin bed 12 is acrylic (PMMA) layer.That is to say, on the upper surface of layer of polycarbonate 10, be compounded with one deck acrylic layer 12, then on the surface of acrylic layer 12, carry out stiffened, for example, adopt spraying technology will add hard formation 11 and be sprayed on transition resin bed 12 surfaces.Now because the degree of crystallinity of acrylic layer 12 is higher, its surperficial stiffened can obtain than higher hardness add hard formation 11, more than hardness can reach 5H, and the overall flexibility of sheet material 1 is better, can carry out the operations such as bending of large radian.If what separately can only obtain maximum hardness 2H hardness at the surperficial stiffened of layer of polycarbonate 10 adds hard formation 11.
Particularly, add hard formation 11 and require have good planarization and light transmittance, light transmittance is greater than 90%, guarantee fully curing, to obtain high hardness; In addition, adding hard formation 11 need to have certain ductility, guarantees when moulding stretches not by drawing crack.
Acrylic layer 12, for to be compounded in the resin bed on layer of polycarbonate 10, requires light transmittance higher than 92%, and good forming ability has good adhesive force with layer of polycarbonate 10, and both thermal contraction deflections are close.
Layer of polycarbonate 10 is the matrix resin of sheet material 1, requires light transmittance higher than 90%, and good forming ability.
As shown in Figure 1, according to the mobile terminal shell 100 of the utility model preferred embodiment, comprise: sheet material 1, patterned layer 2 and background layer 3, sheet material 1 is by layer of polycarbonate 10, transition resin bed 12 and add hard formation 11 and form, background layer 3 is ink layer, now mobile terminal shell 100 machine-shaping in the following way: by the sheet material of selecting 1 in oven for baking, to remove internal stress wherein, prevent that in printing or forming process Stress Release causes cracking or other is bad.Toasted and cooling after; at the lower surface of layer of polycarbonate 10, use the required LOGO of ink printing and other pattern to form patterned layer 2; after dry; printing background color or protection ink are to form background layer 3; to product, give different colors and protect patterned layer 2 not to be damaged in operating process; guaranteeing has release agent or similar additive in last one deck background ink of background layer 3, and while preventing subsequent forming, ink adheres on mould.
After being completed for printing, ink setting is complete, be then placed in high-pressure molding mould and carry out high-pressure molding, mold required shape, take out cooling after, by CNC(computer-aided, process) all leftover bits and pieces of material are cut away, obtain required product.
Wherein, it should be noted that, high-pressure molding refers to the pressure by gases at high pressure, softening sheet material 1 is formed into the process of required form.CNC refers to milling cutter, according to predefined Program path, cuts and obtains product.
