Problems solved by technology

[0007] Since most of the current packaging boxes are made of wood or cardboard, resulting in a waste of resources, and most of the foam materials used have low density, which is easy to cause white pollution. In order to solve the problems existing in the production of packaging boxes, the present invention proposes a new Foam material, and the packaging box made of this foam material, the packaging box made by this preparation method is environmentally friendly, firm, and cost-effective

Embodiment 1

[0039] The quality of raw material components is: polystyrene resin 100kg; sodium bicarbonate 850g; silicone oil 65g; SECCO 825 modified polystyrene resin 12.5kg; industrial starch 4kg;

[0040] First, make two pairs of molds placed on the extrusion port. The longitudinal section of the mold is "L" shaped, the width of the box cover mold is about 35mm, and the width of the box bottom mold is 60mm.

[0041] Then add the above-mentioned components into the material box, and heat and stir in the material box until the material melts. The foaming agent sodium bicarbonate generally starts to foam above 120°C. The foaming agent sodium bicarbonate is fully foamed. When the temperature reaches 250 degrees Celsius, the molten material is extruded from the screw extruder into the port die, and the foam strip passes through the port die for initial molding. The surface is compounded with a PVC film layer printed with the required texture, the processing temperature is 220°C, and then coo...

[0048] The quality of raw material components is: polystyrene resin 90kg; sodium bicarbonate 800g; silicone oil 46g; Panjin 304 modified polystyrene resin 11kg; industrial starch 2.5kg;

[0049] First, make two pairs of molds placed on the extrusion port. The longitudinal section of the mold is "L" shaped, the width of the box cover mold is about 40mm, and the width of the box bottom mold is 65mm.

[0050] Then add the above-mentioned components into the material box, and heat and stir in the material box until the material melts. The foaming agent sodium bicarbonate generally starts to foam above 120°C. The foaming agent sodium bicarbonate is fully foamed. When the temperature reaches 250 degrees Celsius, the molten material is extruded from the screw extruder into the port die, and the foam strip passes through the port die for initial molding.

Abstract

The invention relates to a foamed plastic packing box and a preparation method thereof. Aim at solving problems produced in packing box production thereby satisfying increasing requirements from people on packing boxes, the invention provides the foamed plastic packing box and the preparation method thereof. The foamed plastic packing box comprises: by weight, 90 to 110 parts of polystyrene resin, 0.8 to 0.9 parts of sodium bicarbonate NaHCO3, 0.046 to 0.078 parts of silicone oil, 11 to 14 parts of modified polystyrene resin and 2.5 to 5 parts of industrial starch. Compared with the prior art, the foamed plastic packing box reduces environmental pollution, has good environmental benefits, reduces follow-up processes, and has a low cost and a good cost-performance ratio.

Description

technical field [0001] The invention relates to a packing box material, in particular to a packing box foam material and a preparation method thereof. Background technique [0002] With the continuous improvement of Chinese people's living standards, people's quality of life, aesthetic appeal, and consumption concepts continue to improve. Various daily life and consumer goods such as: cigarettes, wine, tea, moon cakes, ginseng, tonics, seafood gift boxes, jewelry Boxes, craft gift boxes, and clothing gift boxes put forward higher requirements, not only requiring environmental protection, simplicity, and no harmful substances such as formaldehyde and chlorine compounds, but also non-toxic, tasteless, light, exquisite, and cost-effective. Reusable and easy recycling of reusable packaging boxes. [0003] Due to the gift box packaging box, its main structure is generally a combination of upper and lower half boxes with similar dimensions. The upper half box is the box cover, an...
