The utility model provides a temperature resistant weather-resistant of PP reflectance coating (polypropylene reflectance coating) on the existing market not enough, yielding, the easy problem of ageing and structural fracture pulverization also lower than the manufacturing cost of PET reflectance coating (high temperature resistant polyester reflectance coating) simultaneously.
Description
Technical Field
The utility model relates to a membrane class electronic material field, especially a reflective membrane.
Background
The reflective films on the market at present are mainly classified into PET reflective films (polyester reflective films) and PP reflective films (polypropylene reflective films). The reflective film is mainly applied to liquid crystal backlight modules, flat light emitting modules, LED light emitting components (light emitting diode light emitting components), ultrathin lamp boxes, crystal lamp boxes and the like. However, the existing PET reflective film has complex production process, large equipment investment and limited thickness; and the PP reflecting film has low density, insufficient temperature resistance and weather resistance, easy deformation and easy aging.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of above-mentioned prior art existence, and provide a low in production cost, the temperature resistant is able to bear or endure the weather nature well, is difficult for the deformation and ageing, prevents the reflectance coating of structural fracture pulverization.
The purpose of the utility model is realized like this:
a reflecting film comprises a PP (polypropylene) film reflecting layer and is characterized in that the upper side and the lower side of the PP film reflecting layer are respectively provided with an upper PET (polyester) film temperature-resistant layer and a lower PET film temperature-resistant layer. The two sides of the PP film reflecting layer of the reflecting film can form good protection for the PP film reflecting layer by arranging the PET film temperature-resistant layer with good optical transparency, weather resistance, abrasion resistance, friction resistance and dimensional stability.
The purpose of the utility model can also adopt the following technical measures to solve:
more specifically, the PP film reflecting layer is made of a foamed biaxially oriented PP film, the upper PET film temperature-resistant layer and the lower PET film temperature-resistant layer are both made of unfoamed biaxially oriented PET films, and the upper PET film temperature-resistant layer and the lower PET film temperature-resistant layer are respectively bonded with the PP film reflecting layer through composite glue.
As a further scheme, the PP film reflecting layer is formed by a single-layer PP film or is formed by compounding a plurality of layers of PP films, and the thickness of the PP film reflecting layer is 0.045 mm-0.4 mm.
The PP film reflecting layer is formed by a single-layer PP film or a plurality of layers of PP films, and the thickness of the PP film reflecting layer is 0.3-0.4 mm. Under the condition of ensuring that the whole thickness of the product meets the requirement, and because the PP film reflecting layer belongs to the functional layer (namely, the layer which can play the most reflecting role), the thickness of the PP film reflecting layer can be properly increased.
As a further proposal, the thickness of the PP film reflecting layer is 0.18 mm-0.25 mm. In general, the thickness of the reflective layer of the PP film can be designed to be moderate.
As a further scheme, the thickness of the PP film reflecting layer is 0.045 mm-0.065 mm, so that the overall thickness of the product is thinner.
As a further proposal, the upper PET film temperature resistant layer is made of a transparent or matte unfoamed biaxially oriented PET film, and the thickness of the upper PET film temperature resistant layer is 0.019 mm-0.075 mm. The lower PET film temperature-resistant layer is made of a transparent or matte unfoamed biaxially oriented PET film, and the thickness of the lower PET film temperature-resistant layer is 0.019 mm-0.075 mm. The thicknesses of the upper and lower PET film temperature-resistant layers may be equal or different. The upper PET film temperature-resistant layer and the lower PET film temperature-resistant layer mainly play a role in protecting the PP film reflecting layer, and meanwhile, the functional influence on the PP film reflecting layer needs to be reduced as far as possible, so that the thickness of the layers is selected to be in a thinner range.
The utility model has the advantages as follows:
the utility model provides a temperature resistant weather-resistant of PP reflectance coating (polypropylene reflectance coating) on the existing market not enough, yielding, the easy problem of ageing and structural fracture pulverization also lower than the manufacturing cost of PET reflectance coating (high temperature resistant polyester reflectance coating) simultaneously.
