Embodiment 1

[0022] Add 100 parts by weight of PE (7042), 500 parts by weight of sodium sulfate, 100 parts by weight of starch and 10 parts by weight of surface treatment agent into a high-speed mixer, stir at a high speed for 30 minutes, and then extrude with a twin-screw extruder Granulation, that is, highly filled transparent masterbatch.

[0023] The prepared high-filling transparent masterbatch was added to LDPE7042 at a weight ratio of 20%, and the sample was tested for performance. The test results are shown in the table below.

Embodiment 2

[0027] Add 100 parts by weight of PE (7042), 600 parts by weight of sodium sulfate, 5 parts by weight of starch and 15 parts by weight of surface treatment agent into a high-speed mixer, stir at a high speed for 20 minutes, and then extrude with a twin-screw extruder Granulation, that is, highly filled transparent masterbatch.

[0028] The prepared high-filling transparent masterbatch was added to LDPE7042 at a weight ratio of 40%, and the sample was tested for performance. The test results are shown in the table below.

[0029] LDPE7042

Embodiment 3

[0031] Add 100 parts by weight of transparent PP, 60 parts by weight of 500-mesh sodium sulfate, 200 parts by weight of amylose and 50 parts by weight of silane coupling agent into a high-speed mixer, stir at high speed for 50 minutes, and then extrude with a twin-screw Machine extrusion granulation, that is, highly filled transparent masterbatch.

[0032] The prepared highly filled transparent masterbatch was added to the film raw material as a filler in a weight ratio of 15%, and the obtained result was close to that of Example 1.

Abstract

The invention discloses a high-transparency filling material prepared from the following raw materials in parts by weight: 100 parts of transparent polyolefin resin, 60-600 parts of sodium sulfate, 0-200 parts of starch and 1-50 parts of surface treating agent. The high-transparency filling material is suitable for high-transparency filling master batches of transparent or semitransparent packing films or packing bags, and by adopting the high-transparency filling material, the problems that the currently used filling materials are poor in transparency and have great influence on the transparency of the packing films are solved.

Description

technical field [0001] The invention relates to the technical field of transparent fillers. More specifically, it relates to a highly transparent filler and its preparation method and application. Background technique [0002] At present, many household electrical appliances have a large packaging film or packaging bag to cover the entire electrical product before leaving the factory, and the user will throw away these packaging films or packaging bags after purchasing the electrical appliance. These packaging films or packaging bags are generally blown from transparent pure materials, and are disposable. In order to enable users to clearly see the electrical appliances inside, manufacturers cannot add talcum powder and calcium carbonate to affect transparency. Non-destructive inorganic powders reduce costs, resulting in a great waste of resources and environmental pollution. [0003] Compared with ordinary filling materials, the biggest feature of transparent filling mate...
