Abstract
The utility model discloses a kind of composite back plate; comprise polyester film, aluminium matter reflector layer, lower polyester film; described upper polyester film is high polyester film thoroughly; described lower polyester film is brilliant white polyester film; upper and lower polyester film can form effective protection; high temperature resistant, not yielding; middle aluminium matter reflector layer reaches high-efficiency reflective film effect; backboard has the protective effect of backboard and the reflex of reflectance coating simultaneously; reflectance coating and backboard in installation process is avoided not to fit phenomenon; greatly reduce the consumption of aluminium simultaneously, save cost.
Description
Technical field
The utility model relates to a kind of back board structure, particularly relates to the back board structure being applied to light fixture aspect.
Background technology
In current LED flat lamp on the market, backboard generally adopts aluminium, aluminum backboard needs to make backboard through wire drawing oxidation, recycling for the later stage is very inconvenient, Product recycling utilizes inconvenient, and reflectance coating is expanded material, needs backboard and reflectance coating smooth laminating during assembling, assembling process precision requirement is high, product rejection rate is high, produces larger material unaccounted-for (MUF).
Summary of the invention
The utility model provides a kind of integral type composite back plate to solve deficiency of the prior art, reaches the bilayer effect of protection and reflection, reduces the thickness of backboard and reflectance coating, reduce the use amount of aluminium simultaneously, greatly saved cost.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of composite back plate; comprise polyester film, aluminium matter reflector layer, lower polyester film; described upper polyester film is high polyester film thoroughly; described lower polyester film is brilliant white polyester film; upper and lower polyester film can form effective protection; high temperature resistant, not yielding; middle reflective bisque reaches high-efficiency reflective film effect; backboard has the protective effect of backboard and the reflex of reflectance coating simultaneously; reflectance coating and backboard in installation process is avoided not to fit phenomenon; greatly reduce the consumption of aluminium simultaneously, save cost.
As a kind of preferred version of composite back plate described in the utility model, the reflective bisque of described aluminum is the minute surface aluminium lamination be plated on polyester film, and the coefficient of aluminizing of aluminium lamination is 600A, and light reflectivity reaches more than 95%, and preferred aluminum layer thickness is at 1-10 μm.
As a kind of preferred version of composite back plate described in the utility model, bonded by glue between described aluminium lamination and lower polyester film, preferred glue is two component aluminium foil glue, can reach splendid compound adhering effect, can reach service time of more than 20 years and not easily absciss layer in conventional environment.
As a kind of preferred version of composite back plate described in the utility model, described upper polyester film and lower polyester film are PET (PET) polyester film, because the hardness of PET polyester film is higher, plasticity is strong, against weather is stronger, cheap and be suitable for batch production make, therefore we carry out producing this composite back plate with PET polyester film, and preferred upper polyester film and lower polyester film thickness are at more than 0.1mm.
Accompanying drawing explanation
Fig. 1 is described composite back plate structural representation.
Wherein: 1, upper polyester film 2, aluminium matter reflector layer 3, lower polyester film
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, a kind of composite back plate, comprise polyester film 1, aluminium matter reflector layer 2, lower polyester film 3, described upper polyester film is high PET polyester film thoroughly, and described lower polyester film is brilliant white PET polyester film, aluminium matter reflector layer is the aluminium lamination be plated on polyester film, high PET polyester film thickness is thoroughly 0.1mm, and aluminum layer thickness is 3 μm, and aluminium lamination coefficient of aluminizing is more than 600A, bond with two component aluminium foil glue between aluminium lamination and brilliant white PET polyester film, brilliant white PET polyester film thickness is 0.1mm.The PET polyester film that the saturating PET polyester film of the height used in the present embodiment becomes Nanosolutions GmbH to produce for Nanpu, Nanjing, brilliant white PET polyester film is the ZP12 series brilliant white PET polyester film that south packaging Group Co., Ltd produces, and two component aluminium foil glue of use are Jiangsu Lihe Adhesive Co., Ltd. LH-3721 type glue.
Although be illustrated embodiment of the present utility model in description, these embodiments just as prompting, should not limit protection domain of the present utility model.In the scope not departing from the utility model aim, carry out various omission, displacement and change all should be included in protection domain of the present utility model.
