Description
Technical Field
The invention relates to an environment-friendly packaging material; in particular to an environment-friendly packaging material prepared from fly ash and a preparation method thereof.
Background
With the rising of environmental awareness and the establishment of the concept of resource recycling, modern people increasingly pay more attention to whether the environment is properly protected and whether byproducts generated by industrial and electric operation can be recycled.
Taking coal-fired power generation as an example, the annual output of coal ash in a coal-fired thermal power plant is up to millions of tons during operation. The fly ash is collected from the chimney of the coal-fired thermal power plant, and the bottom ash is collected from the furnace bottom of the boiler of the coal-fired thermal power plant. Specifically, the fly ash can be obtained from an electromagnetic dust collector in a boiler of a coal-fired thermal power plant.
Whether the bottom ash or the fly ash is mostly digested in a land filling manner, the bottom ash or the fly ash which is not in good condition is buried directly in the land filling manner, so that serious land pollution is caused, and the buried land cannot be used in the next decades.
As known from related researches, fly ash is most commonly used as an additive of cement or concrete and can also be used as a filler of flowable backfill soil or general backfill soil; in recent research, fly ash is used as a slow-release fertilizer after being sintered.
However, as is clear from the above, fly ash is not effectively used in a wide variety of fields because the fly ash is not digested to a low degree in other application fields than as an additive for cement/concrete and a filler for backfill.
Disclosure of Invention
In view of the above, the present invention provides an environment-friendly packaging material of fly ash, which is prepared by blending fly ash and plastic and extruding the mixture to form an environment-friendly packaging material of fly ash; it can be used as packing paper or decorative paper.
The invention achieves the aim, and the environment-friendly fly ash packaging material provided by the invention comprises 25-40 wt% of fly ash, 25-40 wt% of inorganic mineral powder, 25-40 wt% of plastic and 1-2 wt% of auxiliary agent; the fly ash, the inorganic mineral powder, the plastic and the auxiliary agent are mixed and granulated to form a granular material, and the granular material can be processed to form the fly ash environment-friendly packaging material.
Another objective of the present invention is to provide a method for manufacturing an environment-friendly fly ash packing material, which comprises at least the following steps:
mixing and granulating 25-40 wt% of fly ash, 25-40 wt% of inorganic mineral powder, 25-40 wt% of plastic and 1-2 wt% of auxiliary agent to form a granular material; and
and processing the granular material to form the environment-friendly fly ash packaging material.
The invention has the effects that the fly ash, the inorganic mineral powder and the plastic are mixed and processed to form the fly ash environment-friendly packaging material; the fly ash can be used as a light and thin packaging paper or a decorative paper which is increased in stiffness, so that the application field of the fly ash is increased, and the aim of increasing the consumption of the fly ash is fulfilled.
