Problems solved by technology

However, the added dioctyl sebacate, dioctyl phthalate, and tribasic lead sulfate are toxic and have poor environmental protection performance; the compatibility between the added components is not good, and in the long-term use process It is prone to extravasation, which leads to poor performance stability of wood-plastic plastics. In addition, it does not contain wood components, so it is difficult to achieve the texture of wood

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a high-toughness wood-plastic plastic and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of social productivity and the continuous improvement of people's quality of life, people's understanding of building an energy-saving, environmentally friendly and conservation-oriented society has gradually deepened. It is in this situation that wood-plastic plastics came into being and are widely used in industries such as building materials, furniture and logistics packaging. Wood-plastic plastic is a new type of material made of natural fibers, thermoplastic resins and specific processing aids. It has the advantages of both wood and plastic, and is of great significance in environmental protection and alleviating the scarcity of forest resources. [0003] During the production and use of wood-plastic plastic, it w...
