肉桂醇改善竹粉/聚丙烯复合材料的防霉性能

o improve anti-mold properties of bamboo flour/polypropylene (PP) composites, the cinnamylalcohol was used. The mildew resistance of cinnamylalcohol and its thermal stability were studied. Additionally, the effects of cinnamylalcohol on the mold resistance, mechanical properties, and color of injection molding composites were investigated. The results showed that the growth and reproduction of moulds were inhibited by cinnamylalcohol effectively. Cinnamylalcohol still showed good thermal stability to anti-mold when the temperature was 200℃. The suitable dosage amount of cinnamylalcohol was 0.6 wt% of composite; at this time, the infection values and fungicidal effectiveness of composites were 1.8 and 53.8% after 28-day mold testing. Adding cinnamylalcohol in bamboo plastic composites had no significant impacts on bending performance and surface color. The bending strength and bending modulus were 49.78 MPa and 3927.68 MPa, respectively. The color change only 1.9, compared to the composites without cinnamylalcohol.
