Abstract

The invention discloses a wear-resistant and flame-retardant wood-plastic and a preparation method thereof. The wood-plastic comprises the following components in parts by weight: 50-80 parts of modified plant fiber, 40-60 parts of basalt long fiber, 50-80 parts of PE 20-40 parts of composite flame retardant, 10-15 parts of lubricant, 5-10 parts of calcium carbonate, 5-8 parts of silicon dioxide, 3-5 parts of montmorillonite, 2-4 parts of carbon black, antioxidant 1-3 parts of agent, 0.5-1.5 parts of coupling agent and 0.5-1 part of pigment. The advantage is that the present invention prepares a wood-plastic material with outstanding mechanical properties, wear resistance and flame retardancy by optimizing the components and component contents, which can meet the needs of the high-end market and has a very Obvious economic and social benefits.

Description

technical field [0001] The invention relates to a wood-plastic material, in particular to a wear-resistant and flame-retardant wood-plastic material and a preparation method thereof, belonging to the technical field of materials. Background technique [0002] Wood-plastic, that is, wood-plastic composites (Wood-Plastic Composites, WPC), is a new type of composite material that has been booming at home and abroad in recent years. More than 35%-70% of wood flour, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce plates or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. The board formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called extruded wood-plastic composite board. [0003] The Chinese patent with the application number CN201610073541.6 disc...
