Environment-friendly high-strength fragrant wood-plastic material and preparation method thereof

Abstract

The invention discloses an environment-friendly high-strength fragrant wood-plastic material and a preparation method thereof. The environment-friendly high-strength fragrant wood-plastic material isprepared from the following raw materials in parts by weight: 60-70 parts of amino resin, 7-9 parts of modified bamboo powder, 7-9 parts of modified diatomite, 8-14 parts of acrylate impact modifier,5-7 parts of coupling agent, 8-10 parts of mixing rubber, 30-40 parts of waste straw, 20-30 parts of waste wood, 3-5 parts of heat stabilizer, 12-18 parts of natural plant essential oil, 8-12 parts offlame retardant additive, 8-12 parts of wear-resistant additive, and 10-14 parts of processing agent. The wood-plastic material disclosed by the invention is good in wear resistance, good in corrosive resistance, flame retardant, free from formaldehyde and free from pollution; furthermore, the wood-plastic material is excellent in antibacterial performance, mothproof, humidity resistance and capable of purifying the air; the product emits the plant fragrance; and meanwhile, the preparation method disclosed by the invention adopts a large number of waste wood materials, the resource is saved,the environment is protected, the cost is low, the raw materials are easy to obtain, and the process is concise. The environment-friendly high-strength fragrant wood-plastic material has high practical value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of wood-plastic panels, in particular to an environment-friendly, high-strength, fragrance-free wood-plastic material and a preparation method thereof. Background technique [0002] As an emerging environmental protection material, wood-plastic material is mainly made of plant fiber material, and plastic is added to form a composite material with wide applicability. In the processing of wood-plastic composite materials, because wood fibers have strong polarity and hydrophilicity, while plastics are non-polar and non-hydrophilic, the compatibility between wood fibers and plastics is very poor, and the interface is sticky. The resulting force is also very small, so it is very difficult to combine wood with strong water absorption and plastic with hydrophobicity, and it will also affect the mechanical properties of wood-plastic composites. Moreover, due to the strong interaction between wood fibers, its disper...

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.
