Special-shaped panel prepared from thermoplastic plastics filled with mixture of wheat straw fibers and powder coal ash as well as preparation method of special-shaped panel

Abstract

The invention discloses a PVC (polyvinyl chloride) production and decoration special-shaped panel filled with regenerated powder coal ash and wheat straw. A core layer of the PVC special-shaped panel is prepared by taking PVC resin, power coal ash and wheat straw broken powder materials with auxiliary raw materials as filling materials, and the core layer wraps a hard PVC layer so as to form a combined special-shaped panel. The invention also discloses a preparation method of the special-shaped panel prepared from thermoplastic plastics filled with the mixture of wheat straw fibers and powder coal ash. According to the technical scheme provided by the invention, wood material consumption is reduced, and the aims of environment protection and resource conservation are achieved; the special-shaped panel prepared by adopting the preparation method achieves the same using and decoration effects with the special-shaped panel prepared in the prior art.

Description

technical field [0001] The invention belongs to the field of materials. More specifically, the invention relates to a special-shaped board made of thermoplastic plastic after mixing wheat straw fiber and fly ash and a preparation method thereof. Background technique [0002] Most of the decorative special-shaped plates in the prior art use wood powder as filler or inorganic powder to be extruded and then laminated or printed. Fly ash is the ash after coal combustion in coal-fired power plants. It is a large-volume, The waste solids that pollute the environment cause pollution to the environment; wheat straw is mostly discarded in the field after the crops are harvested. Wheat straw is an organic matter symbiotic with organic fiber and starch. After the summer harvest, the thick smoke from burning wheat straw pollutes the surrounding environment, especially near the airport, causing dangerous factors for aircraft take-off and landing. The burning of wheat straw not only cause...

[0002] Most of the decorative special-shaped plates in the prior art use wood powder as filler or inorganic powder to be extruded and then laminated or printed. Fly ash is the ash after coal combustion in coal-fired power plants. It is a large-volume, The waste solids that pollute the environment cause pollution to the environment; wheat straw is mostly discarded in the field after the crops are harvested. Wheat straw is an organic matter symbiotic with organic fiber and starch. After the summer harvest, the thick smoke from burning wheat straw pollutes the surrounding environment, especially near the airport, causing dangerous factors for aircraft take-off and landing. The burning of wheat straw not only causes waste of resources but also pollutes the environment, and even causes forest fires, which has caused great harm to environmental protection.
