Description

A kind of automobile window films and preparation technology thereof reducing visible reflectance
Technical field
The present invention relates to film production field, particularly relate to a kind of automobile window films and the preparation technology thereof that reduce visible reflectance.
Background technology
Vacuum thermal evaporation film belongs to second generation fenestrated membrane product, and base material uses aluminizer, and this type of film results from early 1990s.Vacuum thermal evaporation technique is evaporated on base material by aluminium lamination, reaches effect of heat insulation.This type of film has entered our usually said metal film field, possesses more lasting thermal insulation, but outstanding weakness is reflective higher, and interrupt the view, Ministry of Public Security's relevant laws and regulations all have requirement to visible reflectance inside and outside automobile window films.The design of fenestrated membrane product also will consider that internal reflection is less than external reflectance, plays the effect of secret.
Summary of the invention
The object of the present invention is to provide a kind of automobile window films and the preparation technology thereof that reduce visible reflectance, to solve the existing vacuum thermal evaporation film problem high to visible light reflectance.
In order to realize above-mentioned object, adopt following technical scheme.A kind of automobile window films reducing visible reflectance, comprise the scratch resistant layer, core layer, mounting layer and the mould release membrance that connect successively, described core layer comprises the primary colors film, composite bed and the aluminizer that connect successively, described aluminizer comprises the face of aluminizing and non-face of aluminizing, and described composite bed is connected with the face of aluminizing of aluminizer.Scratch resistant layer adopts high-grade resin composite material; protection fenestrated membrane surface can not be scratched easily or scratch, and mounting layer adopts the pressure sensitive adhesive of acrylic compounds, for fenestrated membrane is arranged on vehicle glass; mould release membrance, mainly for the protection of mounting layer, is first peeled off when installing fenestrated membrane.Core layer is the core of fenestrated membrane, play anti-dazzle, explosion-proof, every the major function of ultraviolet, the fenestrated membrane such as heat insulation, aluminizer can effectively intercept ultraviolet and heat, recycling primary colors film is to the absorption characteristic of visible ray, primary colors film effectively can absorb incident light and aluminizer and to aluminize the reverberation in face, thus it is overall to visible light reflectance to significantly reduce fenestrated membrane.
Described scratch resistant layer can be connected with primary colors film, and the non-face of aluminizing of described aluminizer is then connected with mounting layer.This structure is the visible reflectance utilizing primary colors film to reduce product scratch resistant layer one side.
Described scratch resistant layer also can be connected with the non-face of aluminizing of aluminizer, and described primary colors film is then connected with mounting layer.This structure is the visible reflectance utilizing primary colors film reduction product and vehicle glass to paste one side.
Reduce a preparation technology for the automobile window films of visible reflectance, comprise the following steps:
Compound is carried out by composite bed in the face of aluminizing of S1, primary colors film and aluminizer, forms core layer;
S2, core layer one side be first coated with mounting layer, then with mould release membrance compound;
S3, core layer another side coating scratch resistant layer.
Face of the aluminizing surface tension of aluminizer is low, if for being coated with scratch resistant layer and mounting layer, easily causes poor adhesive force and fenestrated membrane to tear cull, so select the face of aluminizing of aluminizer to be connected with composite bed from glass; The face of aluminizing of aluminizer belongs to easy scuffing face, therefore step S1 is first by the face of aluminizing of aluminizer and primary colors film compound, plays the effect protecting face of aluminizing.If core layer is first coated with scratch resistant layer, due to the smoothness of scratch resistant layer, walk film instability, when easily causing being coated with mounting layer, compound is bad; And if mould release membrance be first coated with after mounting layer with core layer compound, then produce the phenomenon of water ripples after causing pad pasting, therefore step S2 is first at the coated on one side mounting layer of core layer, then with mould release membrance compound.Because coating before and compound make now half-finished thickness comparatively large, so after step S3 is coated with scratch resistant layer, carry out the processing that UV has solidified scratch resistant layer.
The non-face of aluminizing of the aluminizer of core layer can be selected in step S2 to be first coated with mounting layer and with mould release membrance compound, utilize primary colors film to reduce the visible reflectance of product scratch resistant layer one side.
Also the primary colors film of core layer can be selected in step S2 to be first coated with mounting layer and with mould release membrance compound, utilize primary colors film to reduce product and vehicle glass and paste visible reflectance simultaneously.
Compared with prior art, the present invention utilizes face of the aluminizing compound of primary colors film and aluminizer, the heat-proof quality that aluminizer is excellent can be played, significantly reduce again the visible reflectance of fenestrated membrane entirety, aluminizer is enable to be applied to automobile window films field better, can not be restricted because of its reflective characteristic, simultaneously the performance such as explosion-proof thermal insulation of fenestrated membrane entirety have also been obtained lifting.
