Example Embodiment
[0037] Example 1
[0038] A bamboo fiber reinforced material, obtained according to the following method:
[0039] (1) Weigh 100 parts of polypropylene; 20 parts of bamboo fiber; 5 parts of toughening agent; 2 parts of compatibilizer; 0.5 part of organic antibacterial agent; 5 parts of inorganic antibacterial agent; 0.4 part of coupling agent; plasticizer 3 parts of anti-oxidant; 0.5 part of antioxidant;
[0040] Wherein, the bamboo fiber is obtained by the following method: firstly, the bamboo is cut into a long strip of bamboo along the growth direction of the bamboo, then the bamboo sheet is rolled with a press, and the transverse grinding of the bamboo fiber is made to expand the bamboo fiber. The bamboo fibers are uniformly dispersed and screened through a screen after drying to obtain the bamboo fibers;
[0041] The diameter of the prepared bamboo fiber is 200um~500um, the length-diameter ratio is 1:(10~50), it has been dried before use, and the moisture content is low...
