Abstract

The invention relates to an environmental-friendly wood plastic material and a preparation method thereof, belonging to the field of environmental-friendly materials. According to the environmental-friendly wood plastic material, raw materials used for preparing the wood plastic material are composed of the following components in parts by weight: 30-40 parts of pre-irradiated HDPE, 0.5-2 parts of a photoinitiator and 50-70 parts of functional master batch, wherein the functional master batch comprises formaldehyde degradation powder. The environmental-friendly wood plastic material disclosed by the invention has the effect of degrading formaldehyde, and the materials are not layered in the preparation process, so that the active ingredients do not separate out or are not lost, and the service life of the environmental-friendly material can be effectively prolonged.

Description

technical field [0001] The invention relates to an environment-friendly wood-plastic material and a preparation method thereof, belonging to the field of environment-friendly materials. Background technique [0002] Wood-plastic composite material (ecological wood) is a new product that can replace wood developed through technological innovation and recycling of waste wood powder. While saving natural resources, wood-plastic not only has natural wood texture and grain, but also has technical properties such as water resistance, corrosion resistance, fire prevention, mildew resistance, pollution-free, and recyclable. [0003] Given that the unpleasant smell of waste wood powder mainly comes from the benzene-containing adhesives used in artificial wood boards, paints and soft furniture used in manufacturing, formaldehyde, benzene, TVOC and other pollutants emitted from these decorative materials often contain irritating substances. Nasal harmful odor, some also produce aromat...
