Example Embodiment

[0035] Example 1:

[0036] See figure 1 , A manufacturing process of biaxially stretched color base film for protection of electronic product manufacturing process, including the manufacture of color masterbatch and the use of five-layer biaxially stretched equipment to produce color film. The manufacturing of color masterbatch is produced by a tandem screw extruder. The production of color film with five-layer biaxial stretching equipment includes the following steps: drying, extrusion, casting, longitudinal stretching, transverse stretching, heat treatment and winding. Extrusion includes main extruder extrusion and auxiliary extruder extrusion. Out, the auxiliary extruder includes four auxiliary extruders, and one of the auxiliary extruders is the auxiliary extruder with colored layer, (the auxiliary extruder with colored layer: set the temperature 220-230 degrees, other Three auxiliary extruders: the temperature of the first zone is 220 degrees, and the other areas are 250 deg...

Abstract

The invention discloses a manufacturing process of a biaxially stretched color base film for manufacture process protection of electronic products, and belongs to the field of manufacturing color basefilm. The manufacturing process comprises the steps of manufacture of a color masterbatch and manufacture and production of a color film by using a five-layer biaxial stretching device, specificallythe color masterbatch is produced by using a tandem type screw extruder; and the production of the color film by using the five-layer biaxial stretching device includes the following steps: drying, extruding, casting, longitudinal stretching, transverse stretching, heat treatment and winding, specifically the step of extruding includes extruding by a main extruder and extruding by using four auxiliary extruders. the four auxiliary extruders used in the step of extruding by using the four auxiliary extruders are able to make the film surface color be uniformly distributed, less in crystal point, less in bubbles, and high in gloss; the corona surface has a uniform corona value and no corona on the back surface, and the non-corona surface has no glue; the pollutant to a main batching system of a production line is less; and products are converted quickly after production is completed.

Description

Technical field [0001] The invention relates to the manufacturing field of color base films, and more specifically, to a manufacturing process of a biaxially stretched color base film for protecting electronic product manufacturing processes. Background technique [0002] BOPP is the abbreviation of "Biaxially Oriented Polypropylene", that is, biaxially oriented polypropylene film. Its production is to first make a sheet or thick film from the polymer polypropylene melt through a narrow and long machine head, and then in a special stretching machine, at a certain temperature and a set speed, simultaneously or step by step The film is stretched in two vertical directions (longitudinal and transverse), and after proper cooling or heat treatment or special processing (such as corona, coating, etc.). [0003] Commonly used BOPP films include: ordinary biaxially oriented polypropylene film, heat-sealing biaxially oriented polypropylene film, cigarette packaging film, biaxially oriented...
