Problems solved by technology

However, on the one hand, the power consumption of the lighting device is astonishing. On the other hand, for example, the most common fluorescent tube lighting device at present, due to the congenital cylindrical design of the fluorescent tube, the light is projected in a 360-degree direction, and the upper half of the tube Part of the light irradiated upwards is not directly projected on the light-receiving surface, which belongs to invalid light. For this part of the light, the general design is only to use metal with luster on the surface (such as thin aluminum, aluminum or stainless steel), or coated with Chemical substances with reflective ability (such as aluminum oxide, etc.), used as light source reflectors
However, once any metal or reflector coated with chemical substances is in contact with the air for a long time, it will be oxidized and deteriorated or corroded by chemicals such as acids and alkalis in the air, or peeled off due to temperature and oxidation, and lose its reflective ability

preparation example Construction

[0023] The preparation method of a kind of reflective material provided by the present invention comprises: 30~50wt% barium sulfate powder, 5~8wt% titanium dioxide, 5~10wt% pearl powder, 10~20wt% film-forming aid, the rest It is an organic solvent, and it forms an organic fusion after thorough mixing.

[0024] A kind of reflective film provided by the invention, such as figure 1 As shown, it includes a substrate 12, the substrate 12 is coated with the above-mentioned reflective material coating 14, the reflective material coating is coated with an ultraviolet absorber, and the ultraviolet absorber coating 16 is coated with It has a transparent protective film 18 .

[0025] The reflective film can be applied to the reflective surface of the reflective plate of the lighting device. Accordingly, the present invention also provides a reflective plate for a lighting device, comprising a substrate, and the reflective film as described above is provided on the surface of the substr...

Embodiment 1

[0036] 30wt% of barium sulfate powder, 5wt% of titanium dioxide, 5wt% of pearl powder, 10wt% of film-forming aids, and the rest are organic solvents, mixed at room temperature, and fully stirred to form an organic fusion.

[0037] This reflective material is coated on the substrate, and then coated with an ultraviolet absorber UV coating, and then a transparent protective layer is formed by thermocompression on the outermost layer, thus forming a reflective film, which is applied to lighting The reflection efficiency of the reflector of the device can reach about 90%. However, the reflection efficiency of ordinary aluminum is only more than 80%, and the price is expensive.

Embodiment 2

[0039] 40wt% of barium sulfate powder, 7wt% of titanium dioxide, 8wt% of pearl powder, 15wt% of film-forming aid, and the rest are organic solvents, mixed at room temperature, and fully stirred to form an organic fusion.

[0040] The reflection efficiency of the reflective plate formed by the reflective material can reach about 92%.

Abstract

The invention provides a reflective material, a reflective membrane and a preparation method thereof. The reflective material comprises 30 to 50 weight percent of barium sulfate powder, 5 to 8 weight percent of titanium white powder, 5 to 10 weight percent of pearl powder, 10 to 20 weight percent of film forming aid and the balance of organic solvent. The reflective material provided by the invention has the advantages of high reflectivity, oxidation and corrosion resistance, low cost and the like.

Description

technical field [0001] The invention relates to the field of optical materials, in particular to a reflective material applied to lighting devices, a reflective film and a production and preparation method thereof. Background technique [0002] Since the 1960s, reflective materials and reflective films have been widely used in engineering signs, advertising display, decoration, solar energy collection, liquid crystal display and other fields. The reflective film can be divided into glass bead type and micro prism type according to its different retroreflection principles. Among them, the reflective film using glass bead type is divided into three types: flexible grade, engineering grade and high-strength grade according to its physical and reflective properties. The reflective performance of the grade reflective film is poor, but it has good flexibility and is widely used in motor vehicle license plates; the reflective performance of the engineering grade reflective film is ...
