Problems solved by technology

However, the disadvantage of traditional calcium-plastic materials is that their plastic content is high, and it takes a long time for plastics to degrade by themselves in nature.
Today, with the rapid development of urbanization and industrialization, the disposal of garbage is the most troublesome thing for governments all over the world. Plastic products account for a large proportion of garbage. Plastic products degrade faster on the surface under the influence of temperature difference and wind and rain, such as centralized burial. Plastic products can last for decades or even hundreds of years. Combustion is a quick way to eliminate plastics, but combustion will produce toxic and carcinogenic gases, and its pollution level is higher than that of natural degradation.

Embodiment (1

[0015] Low pressure polyethylene (HDPE) 20%, calcium carbonate 37.5%, corn straw 7.1%, calcium plastic waste box 22%, antioxidant 4%, stearic acid 0.5%, titanium dioxide 2.5%, zinc stearate 2.5%. The calcium-plastic plate manufactured according to the proportion formula of the above-mentioned embodiment (1) has poor natural degradability and cannot show its characteristics.

Embodiment (2

[0017] Low pressure polyethylene (HDPE) 20%, calcium carbonate 37.5%, corn straw 13%, calcium plastic waste box 22%, antioxidant 4%, stearic acid 0.5%, titanium dioxide 2.5%, zinc stearate 2.5%. The calcium-plastic plate manufactured according to the proportion formula of the above-mentioned embodiment (2), the hardness of the calcium-plastic plate decreases, the quality of the plate decreases, the material is loose, and is not durable.

Embodiment (3

[0019] Low pressure polyethylene (HDPE) 20%, calcium carbonate 37.5%, corn straw 11%, calcium plastic waste box 22%, antioxidant 4%, stearic acid 0.5%, titanium dioxide 2.5%, zinc stearate 2.5%. The calcium-plastic plate manufactured according to the proportion formula of the above-mentioned embodiment (3) has a moderate hardness, and the plate is convenient and practical, and it degrades quickly when it is discarded after use.

Abstract

The invention discloses an easily decomposed corrugated container calcium-plastic material. The easily decomposed corrugated container calcium-plastic material is mainly prepared from following raw materilas by weight percentage: 18-23% of low-voltage polyethylene (HDPE), 30-42% of calcium carbonate, 7-13% of maize straw, 16-28% of calcium-plastic waste boxes, wherein the easily decomposed corrugated container calcium-plastic material comprises the following auxiliary materials by weight percentage: 3-5% of antioxidant, 0.3-0.7% of stearic acid, 2-3% of titanium dioxide and 2-3% of zinc stearate. The preparation method comprises the following steps: A, finishing materials: smashing the maize straw, sieving with a 50-80-mesh sieve, collecting the smashed maize straw powders for later use, smashing the calcium-plastic waste boxes, sieving with a 50-mesh sieve, and collecting the smashed calcium-plastic waste box powder for later use; B, mixing and stirring: uniformly mixing low-voltage polyethylene, calcium carbonate, the antioxidant, stearic acid, titanium dioxide, zinc stearate, the maize straw powder and the calcium-plastic waste box powder in a high-speed mixing machine, extruding in a double-screw extruder at the temperature of 140-160 DEG C, calendaring and cooling to obtain the calcium-plastic material with different thicknesses.

Description

technical field [0001] The invention relates to a calcium-plastic material for easily decomposable corrugated boxes, in particular, the calcium-plastic material is used to add corn stalks to the components, so that the calcium-plastic corrugated board, packing box, packing box, etc. are easy to be degraded in nature, thereby reducing environmental pollution. pollution pressure. Background technique [0002] Calcium plastic material is a kind of packaging material widely used at present. It has the advantages of easy cleaning, corrosion resistance, strong antifouling ability, sound insulation, light weight, firmness, moisture resistance, and good sealing. ) as the main raw material, calcium carbonate as the filler, various additives are added, calendered and thermally bonded into a calcium-plastic single corrugated board, and then shaped by binding. However, the disadvantage of traditional calcium-plastic materials is that it has a high plastic content, and it takes a long t...
