Abstract
The utility model discloses a hardening film for in-mold decorating (IMD). The hardening film comprises a transparent supporting body and a transparent hardening layer coated on the surface of the transparent supporting body, wherein a concavo-convex micro structure is stamped on the transparent hardening layer. The hardening film has high transparency and relatively high haze; the pattern of an IMD product is ensured to be clear, and surface reflection is prevented effectively, so that aims of preventing glares and a polished decorative effect are fulfilled; and the hardening film can be widely applied to glare-prevention treatment and matte panel IMD fields.
Description
Technical field
The utility model belongs to in-mold decoration (IMD) technical field, and particularly a kind of in-mold decoration is used cured film.
Background technology
In-mold decoration (IMD) is meant that product is in mould during ejection formation; Its product surface forms the technology with decorative pattern simultaneously; Generally be pre-formed one have a decorative pattern film, then this film that is formed with decorative pattern is carried out hot-formingly to form predetermined shape, place again in the die cavity of ejection shaping die after this film cut; Preferably melted material is injected in the die cavity, film combines with melted material and forms the product with decorative pattern.Adopt the prepared product of in-mold decoration, its outward appearance adopts application after than ejection formation again and the product that forms pattern has stronger entity sense, and pattern does not exist bad phenomenon such as fade, come off to take place, and it is widely used in the shell of making various product.
In-mold decoration is the international at present surface decoration technique that is in fashion; Be mainly used in the incrustation and the functional panel of household appliances, be commonly used on the appearance component such as panel, sign in handset viewing window eyeglass and shell, washer control panel, refrigerator control panel, Air-Conditioning Control Panel, automobile instrument panel, the multiple field of electric cooker control panel.
Usually; The IMD product that indoor household electrical appliances are decorated is main with high glaze, transparent type cured film; But this product is in some place; As outdoor or usually run into owing to plate surface is reflective when having the environment of light to use down and cause " dazzle " to pollute, " dazzle " seriously polluted application that influences IMD product pattern visuality and product.In addition, the diversification of Along with people's consumption aesthetic standards, more and more people tend to carry out indoor household electrical appliances with mute optic panel material and decorate.So, the IMD cured film of mute light, anti-dazzle or frosted finish effect progresses into people's sight.
At present, make mute light or anti-dazzle of sclerosis handled, its technological means that adopts usually is in hardening coat, to add anti-dazzle particle, through anti-dazzle particle the diffuse reflection effect of surface light is reached the cured film surface and is mute light or frosted visual effect.But; Because the anti-dazzle particle and the coating resin material that are added do not belong to one type of material together, there is some difference for its refraction coefficient, and anti-dazzle particle can cause to a certain degree refraction, large angle scattering and absorption to transmitted light; Make the light transmission meeting of cured film influenced; Directly cause the lack of defination of IMD printed patterns, briefly be exactly the printed patterns color not just, not thoroughly, black such as black matrix, occur greyish black etc.
The utility model content
The utility model technical problem to be solved is: overcome the shortcoming that prior art exists, provide a kind of and can produce frosted finish effect, higher, the better transparent hardened film for in-mold decoration of clear patterns degree of light transmittance.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is:
A kind of transparent hardened film for in-mold decoration, it comprises transparent support and the transparent hard layer that is coated in the transparent support surface, the irregular micro-structural of impression on the transparent hard layer.
Above-mentioned transparent hardened film for in-mold decoration, the degree of depth of said concavo-convex micro-structural is at 5～40 microns.
Above-mentioned transparent hardened film for in-mold decoration, described transparent support another side applies the resin bed that contains polyester, polyurethane, acrylic resin or their mixtures.
Transparent hardened film in the utility model plays " diffuse reflection " and " scattering " effect because of the irregular micro-structural of its hardened layer surface imprint to surface reflection and transmitted light, produces the decorative effect of frosted vision; Because coating is the homogeneous phase material, there be not " veiling glare " simultaneously, avoided influence, make the transmitance of film higher, have advantages such as pattern is more clear, color and luster is more bright-coloured with its IMD product of making to light transmittance and definition.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the profile of the utility model.
Each label is among the figure: 1, transparent support; 2, hardened layer; 3, concavo-convex micro-structural; 4, resin bed.
The specific embodiment
As shown in the figure; The transparent hardened film for in-mold decoration of the utility model; One side at transparent support 1 applies transparent hard layer 2; In the irregular micro-structural 3 of hardened layer surface imprint, the micro-structural that these are concavo-convex degree of roughness can regulate according to the different of operating position with the degree of depth, its degree of depth is preferably between 5～40 microns.These micro-structurals can be regular, also can be irregular.
In order to satisfy the requirement of ink printing, the another side of transparent support 1 applies the resin bed 4 that contains polyester, polyurethane, acrylic resin or their mixtures.
Claims (3)
1. transparent hardened film for in-mold decoration, it comprises transparent support (1) and is coated in the transparent hard layer (2) on transparent support surface, it is characterized in that, transparent hard layer (2) is gone up impression irregular micro-structural (3).
2. transparent hardened film for in-mold decoration according to claim 1 is characterized in that, the degree of depth of described concavo-convex micro-structural (3) is 5～40 microns.
