Abstract

The invention discloses a monolayer two-way stretch light reflection polypropylene film, which is characterized by being manufactured by mixing, extruding, two-way stretching and forming of 30 parts of first component, 60-80 parts of second component and 1-5 parts of third component by mass, wherein the first component comprises 3-48 parts of inorganic particle and 5-50 parts of A resin by mass which are mixed; the second component comprises 50-70 parts of polypropylene resin and 1-20 parts of compatilizer by mass which are mixed; and the third component comprises 0.05-1 part of organic ultraviolet absorbent and 0.5-5 parts of antistat by mass which are mixed. The monolayer two-way stretch light reflection polypropylene film is manufactured by the steps of extruding by an extruder at first, longitudinally stretching, horizontally stretching, thermoforming and forming in a drying tunnel, and can be used for manufacturing light reflection film members with flexibility requirements.

Description

technical field [0001] The present invention relates to a polypropylene film material and its preparation, in particular to a single-layer biaxially stretched light-reflective polypropylene film and a manufacturing method thereof. The single-layer biaxially-stretched light-reflective polypropylene film of the present invention can be used for light reflective films requiring flexibility Manufacturing of components. 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-50μm. The thickness of the reflective she...
