Abstract

The invention relates to wood flour capable of remarkably improving aero-anion concentration, and belongs to the technical field of environmental protection materials. The wood flour is of a sphericalstructure with the diameter being less than 100mum; the spherical structure is provided with multiple holes extending from a surface layer to the inner part; the depth of each hole is less than 50mum; and the wood flour is prepared from the following raw material in parts by weight: 10 to 20 parts of banyan wood flour, 8 to 19 parts of modified starch, 8 to 18 parts of bamboo wood flour, 8 to 15parts of glass fiber, 5 to 12 parts of plant fiber, 4 to 11 parts of coupling agent, and 5 to 12 parts of hokutolite. The wood flour provided by the invention can generate aero-anions and is good forthe physical and psychological health of people after being used for a long time.

Description

technical field [0001] The invention relates to a kind of wood powder, in particular to a kind of wood powder capable of significantly increasing the concentration of aeronegative ions, and belongs to the technical field of environmental protection materials. Background technique [0002] Wood Plastic Composites (WPC for short) is a composite material mainly made of wood or cellulose as the base material and plastic. The invention of wood-plastic composite materials in 1964 was once hailed as one of the top ten scientific achievements in the world that year. As early as the 1980s, wood-plastic composite materials had been researched and applied abroad, and PE / wood powder, PS / wood powder, PP / wood powder, PVC / wood powder and other composite materials were successively developed. And products. [0003] As a material to replace solid wood, wood-plastic composite materials are widely used in various fields of production and life, among which the most widely used is in construct...
