Problems solved by technology

However, its stiffness is high, and it will bring inconvenience to the processing when it is applied to products with complex three-dimensional dimensions.
If there is an acute angle in the product design, the fit will not be tight when covering the acute angle, which will affect the appearance and product quality

Abstract

The invention discloses a composite biaxial tension light reflection polypropylene film. The film is characterized in that the film is formed 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 polypropylene resin and 1-20 weight parts of compatilizers; and the components C are formed by mixing 1-5 weight parts of components D and 95-99 weight parts of polypropylene resin. The film is formed by three layers extruding by an extruder, then longitudinally stretching and transversely stretching, and thermal forming and baking forming; and the product can be used for manufacturing the light reflection film component with flexible requirements.

Description

technical field [0001] The invention relates to a foam-in-bubble structure polypropylene film material for a light reflection plate and its preparation, in particular to a composite biaxially stretched light-reflective polypropylene film and a manufacturing method thereof. The composite biaxially stretched light-reflective polypropylene film of the present invention can be used in Manufacture of light reflective film members with flexibility requirements. Background technique [0002] In the prior art, the light reflective film material has a wide range of uses, and it is used in general daylight lighting, LED lighting, liquid crystal display backlight modules, and advertising signboard light box lighting. In order to achieve high reflectivity, Chinese Patent Application No. 200680031793.7 discloses a polyester extruded sheet immersed in carbon dioxide gas to heat and foam the polyester film to obtain a foamed light reflection sheet with an internal bubble diameter of 50nm-5...
