Abstract

The invention discloses a composite salivate method light reflection sheet. The sheet is characterized in that the sheet is manufactured by sequentially extruding and shaping three layers such as an anti-ultraviolet antistatic mixed upper layer, a bulb-in-bulb layer and an anti-ultraviolet antistatic mixed lower layer; the bulb-in-bulb layer is formed by mixing 30 weight parts of components A, and 60-80 weight parts of components B; the anti-ultraviolet antistatic mixed upper layer and the anti-ultraviolet antistatic mixed lower layer are both formed by components C; the components A are formed by mixing 3-48 weight parts of inorganic particles and 5-50 weight parts of resin A; the components B are formed by mixing 50-70 weight parts of resin B and 1-20 weight parts of compatilizers; the components C are formed by mixing 1-5 weight parts of components D and 95-99 weight parts resin B; and the components D are formed by mixing organic ultraviolet absorbents and antistatic agents. The sheet can be processed into light reflection board components in devices for LED (light emitting diode) illumination, common daylight illumination, and advertisement display board light boxes by means of cutting, folding, plastic adsorption or punching forming.

Description

technical field [0001] The invention relates to a foam-in-foam structure sheet by the salivation method for a light reflection plate, in particular to a composite light reflection sheet by the salivation method and a manufacturing method thereof. The composite salivating method light reflection sheet of the present invention can be processed into light reflection plate components in LED lighting, ordinary daylight lighting, advertising signboard light boxes and the like by cutting, folding, blistering or stamping. Background technique [0002] In the prior art, in order to improve the utilization rate of light and increase the brightness of lighting in ordinary daylight lighting, LED lighting, and advertising signboard light box lighting, metal aluminum plates are usually used as light reflection plates, which are often used to make reflector lamp panels for ordinary daylight lighting and LED lighting. Reflector lamp cup, reflector board for advertising signboard light box l...
