制备方法：（1）木粉预处理：将木材下脚料在磨研机上粉碎成80目的粒径，置于65℃的烘箱中干燥48小时，至含水量4.6％；将干燥好的木粉置于高混机中，调整转速为40r/min，倒入硅烷偶联剂搅拌5min；（2）聚氯乙烯树脂处理：将聚氯乙烯树脂、碳酸钙、硬脂酸置于高混机中，设置温度为70℃，转速为50r/min，混合30min；（3）挤出造粒：设定螺杆挤出机温度140-185℃；将步骤（2）所得聚氯乙烯树脂、碳酸钙、硬脂酸的混合物置于螺杆挤出机中塑化熔融为粘性液体，然后将步骤（1）所得经硅烷偶联剂预处理的木粉加入已成为粘性液体的塑化熔融物中，在螺杆作用下，木粉在塑化熔融物中均匀分散、取向，得到表观均一，分散程度较高的木粉、聚氯乙烯树脂并含有相关助剂的复合体系，再通过相应的口模挤出成型，得到木塑制品；或通过口模和切粒机挤出造粒，形成木塑复合材料粒料，再将所得到的粒料通过模压或注射成型的方法制成最终制品。 Preparation method: (1) Wood powder pretreatment: crush the wood waste into a particle size of 80 mesh on a grinder, and dry it in an oven at 65°C for 48 hours until the water content is 4.6%; put the dried wood powder in In the high mixer, adjust the rotation speed to 40r/min, pour the silane coupling agent and stir for 5 minutes; (2) Polyvinyl chloride resin treatment: put polyvinyl chloride resin, calcium carbonate, and stearic acid in the high mixer, Set the temperature to 70°C, the speed to 50r/min, and mix for 30 minutes; (3) Extrusion granulation: set the temperature of the screw extruder to 140-185°C; mix the polyvinyl chloride resin, calcium carbonate, hard The mixture of fatty acids is plasticized and melted into a viscous liquid in a screw extruder, and then the wood powder pretreated with a silane coupling agent obtained in step (1) is added to the plasticized melt that has become a viscous liquid, and the screw action Under this condition, the wood flour is uniformly dispersed and oriented in the plasticized melt to obtain a composite system of wood flour, polyvinyl chloride resin and related additives with a uniform appearance and a high degree of dispersion, and then extruded through the corresponding die. , to obtain wood-plastic products; or extrude and granulate through a die and a granulator to form wood-plastic composite material pellets, and then make the obtained pellets into final products by molding or injection molding.
本实施例木塑复合材料拉伸强度按GB/T1040-92测试；悬臂梁缺口冲击强度按GB/T1843-80测试；弯曲强度按GB/T1042-79测试。经测试，结果为：拉伸强度26MPa，断裂伸长率高达48%，抗弯强度达到45MPa，I-zod抗冲击强度达16KJ/m2。 The tensile strength of the wood-plastic composite material in this example is tested according to GB/T1040-92; the notched Izod impact strength is tested according to GB/T1843-80; the bending strength is tested according to GB/T1042-79. After testing, the results are: the tensile strength is 26MPa, the elongation at break is as high as 48%, the bending strength is 45MPa, and the I-zod impact strength is 16KJ/m 2 .
