Embodiment 1

[0023] Stone paper tableware, including the following components by weight: 60-80 parts of calcium carbonate, 18-43 parts of polyethylene, 20-35 parts of polypropylene, 0.5-1 part of antioxidant, 0.5-1.5 parts of resin, ACR adhesive, compound Stable modifier 1.5-2.5 parts, wood fiber powder 25-35 parts, fineness 80 mesh.

[0024] The particle size of the calcium carbonate is 3-5 μm.

[0025] The polyethylene biaxially stretched needs to use high-density blown film grade, d=0.95g / cm3, MI=0.05g / 10min.

[0026] The preparation method of stone paper tableware comprises the following steps:

[0027] (1) Put the raw materials into the kneading machine according to a certain proportion for high-speed mixing;

[0028] (2) Modification: the kneader fully disperses and kneads the prepared raw materials to make strips or sheets;

[0029] (3) Granulation: Use a granulator to make strips or sheets into granules, which are convenient for transportation and can provide raw materials for m...

Abstract

The invention discloses rich mineral paper tableware, and a production method thereof. The rich mineral paper tableware comprises calcium carbonate, polyethylene, polypropylene, an anti-oxidant, a resin, ACR adhesive, a composite stabilizing modifier, and wood fiber powder. The production method comprises following steps: (1) the raw materials are delivered into a mixer for high speed mixing at a certain ratio; (2) modification is carried out, wherein a mixture obtained via high speed mixing is subjected to full dispersing and kneading so as to obtain a strip material or a plate material; (3) pelleting is carried out, wherein a pelletizer is used for preparing material particles from the obtained strip material or the plate material, so that it is convenient for transporting, raw materials can be provided for a plurality of parallel production lines, and production efficiency is increased; and (4) production is carried out, wherein the material particles are subjected to extrusion and blow moulding so as to obtain needed products.

Description

[0001] technical field [0002] The invention relates to an environment-friendly tableware, in particular to a stone paper tableware and a preparation method thereof. Background technique [0003] The ecological environment is the basic condition for human survival and development, and the basis for economic and social development. The protection and management of the ecological environment is not only a major issue of international concern, but also related to the sustainable development of my country's economy and society in the 21st century. The forest is the skylight of the ecological environment, the green ark of human beings, and the cradle of civilization. Research and practice have shown that forests maintain the future and destiny of human beings. As the theme of terrestrial ecology, forests are the key to solving the global ecological environment crisis. It can improve the atmosphere. Quality, effective protection of biological diversity, prevention of soil erosio...
