Plant fiber-based wood-plastic geothermal floor and processing method
The invention discloses a plant fiber-based wood-plastic geothermal floor and a processing method thereof. The floor comprises the following raw materials in parts by mass: 20-30 parts of PVC powder, 40-60 parts of modified plant fibers, 20-30 parts of a plasticizer, 15-25 parts of filler powder, 1-5 parts of a lubricant and 1-2 parts of a heat stabilizer. The preparation method of the modified plant fiber comprises the following steps: S1, soaking plant fiber in an acidic sodium chlorite aqueous solution for reaction to obtain hydrolyzed cellulose; s2, the hydrolyzed cellulose is soaked in an alkaline dopamine solution, dopamine is subjected to self-polymerization on the surface of the hydrolyzed cellulose, and polydopamine modified hydrolyzed cellulose is obtained; s3, mixing and reacting the polydopamine modified hydrolyzed cellulose, polyhexamethylene biguanide, sodium hexametaphosphate, soluble transition metal salt and water, and collecting insoluble substances to obtain the modified plant fibers. The geothermal floor has the advantages of good heat conduction efficiency, low thermal expansion rate, difficult buckling deformation, good antibacterial property and flame retardant property, and good market application prospect.
本发明公开了一种植物纤维基木塑地热地板及加工方法，所述地板包括以下质量份的原料，20～30份PVC粉、40～60份改性植物纤维、20～30份增塑剂、15～25份填料粉、1～5份润滑剂、1～2份热稳定剂；其中改性植物纤维的制备方法包括，S1、将植物纤维浸泡于酸性亚氯酸钠水溶液中进行反应，得到水解纤维素；S2、将水解纤维素浸泡于碱性多巴胺溶液中，使得多巴胺在水解纤维素表面自聚合，得到聚多巴胺修饰水解纤维素；S3、将聚多巴胺修饰水解纤维素、聚六亚甲基双胍、六偏磷酸钠、可溶性过渡金属盐、水混合反应，收集不溶物得到改性植物纤维。本发明的地热地板有较好的导热效能、较低的热膨胀率，不易翘曲变形，同时具有良好的抗菌性以及阻燃性能，具有良好的市场应用前景。
