Novel green flame-retardant waterproof wood-plastic composite material and preparation method thereof

Abstract

The invention discloses a novel green flame-retardant waterproof wood-plastic composite material and a preparation method thereof. The novel green flame-retardant waterproof wood-plastic composite material comprises, by weight parts, 8-10 parts of polyurethane elastomer, 30-40 parts of ethylene-vinyl acetate copolymer, 8-12 parts of smoke suppression flame retardant, 7-9 parts of composite fiber,5-7 parts of coupling agent, 4-8 parts of inorganic filler, 40-60 parts of waste wood, 10-20 parts of modified bamboo powder, 2-4 parts of fragrant wood powder, 30-50 parts of polyvinyl chloride resin, 8-12 parts of anti-wear additives and 10-14 parts of processing aids. The novel green flame-retardant waterproof wood-plastic composite material has good anti-moisture, abrasion resistance, corrosion resistance and flame retardant effect, and has excellent antibacterial and anti-insect property; at the same time, in the preparation method, a large amount of waste wood is adopted, which saves resources and protects the environment, the cost is low, the raw materials are easy to obtain, a process is simple, and the novel green flame-retardant waterproof wood-plastic composite material has highpractical value and good application prospects.

Description

technical field [0001] The invention relates to the technical field of wood-plastic panels, in particular to a novel green flame-retardant and waterproof wood-plastic composite material and a preparation method thereof. Background technique [0002] Wood-plastic composite board is a kind of wood (wood cellulose, plant cellulose) as the base material, thermoplastic polymer material (plastic) and processing aids, etc., which are mixed evenly and then heated and extruded by mold equipment. The high-tech green environmental protection material has both the performance and characteristics of wood and plastic, and can replace wood and plastic as a new environmentally friendly high-tech material. With the strengthening of people's awareness of environmental protection and the emphasis on indoor environmental pollution, wood-plastic flooring will replace laminated floors with high water absorption and high formaldehyde content and solid wood floors that are not easy to maintain, wea...

Problems solved by technology

[0003] Because wood-plastic materials contain more plant fibers, during long-term use, especially in humid environments, wood-plastic materials are prone to bacteria growth due to high moisture content, which makes wood-plastic materials moldy and scrapped , thereby increasing the cost of using

[0004] In addition, the current wood-plastic materials still have many performance deficiencies and cannot completely replace wood, which limits the application of products in this industry in the domestic market. For example, wood-plastic materials with PE and PP substrates have relatively high density and self-creep Large, not suitable for applications such as building exterior walls

Other co-extruded wood-plastic products developed in the past two years, such as wood-plastic co-extruded metal materials, wood-plastic co-extruded modified plastics, etc., can partially solve the above problems, but the production process is cumbersome, the product rejection rate is high, and there are two problems in use.
