Problems solved by technology

However, the surfactant is easy to precipitate, and the durability is poor
[0007] From the above progress, it can be seen that the research and application of additives for wood-plastic composite materials are still in their infancy. To make wood-plastic composite materials achieve the effects of flame retardancy, anti-microbial and anti-rodent and ant at the same time, it is necessary to add a variety of additives. , the adding process is cumbersome, and the effect of adding additives cannot be determined
At present, there is no green multifunctional composite additive for wood-plastic composite materials with "one dose and multiple effects" in the market.

Abstract

The invention discloses a green multifunctional composite aid for a wood plastic composite material and a preparation method thereof. The preparation method comprises the following steps of preparing high-stability organic cationic (quaternary phosphonium salt, pyridinium, imide salt and high-stability quaternary ammonium salt) modified clay; mixing a halogen-free flame retardant (zinc borate, ammonium polyphosphate and pentaerythritol), a mouldproof anticorrosive antibacterial agent (organic mouldproof antibacterial agents such as thiazolyl benzimidazole, isothiazolinone and the like) and natural mouse and ant dispelling agent microcapsules uniformly at a high speed under the heating condition; and adsorbing the mixture to the organic cationic modified clay to obtain the green multifunctional composite aid for the wood plastic composite material. The multifunctional composite aid for the wood plastic composite material has the characteristics of high safety, high durability, simple preparation process, low cost and the like. After the multifunctional composite aid is added into the wood plastic composite material, the flame retardance, the antimicrobial property and the mouse and anti preventing performance are improved, and mechanical properties of the wood plastic composite material are not influenced.

Description

Technical field: [0001] The invention belongs to the field of materials, and in particular relates to a green multifunctional composite additive for wood-plastic composite materials and a preparation method thereof. Background technique: [0002] Today, with the depletion of natural resources, the recycling of low-cost waste wood and plastics has become a common concern of industry and science. Wood & Biofiber Plastic Composites (commonly known as WPC in the industry), also known as plastic wood, environmentally friendly wood, technological wood, regenerated wood, plastic wood or poly wood, is based on wood chips, bamboo chips, wheat straw, rice bran, Peanut shells, cotton straws and other primary biomass materials are the main raw materials, and after proper treatment, they can be combined with polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), ABS resin and polystyrene (PS) A kind of reversible recycling, diverse morphological structures, high performance, a...
