Preparation and Performance Analysis of Tannin-Bamboo Powder Bio-based Foaming Materials
摘要
Abstract
Tannin-based foam has received increasing attention due to its light weight,excellent thermal insu-lation and flame retardancy.To improve the brittleness and enhance the compressive strength of tannin-based foams,tannin-bamboo powder bio-based foam(TBF)with a density of 110 kg/m3 was prepared using bamboo powder as an additive.Analyze the influence of bamboo powder on the pulverization rate,pore morphology,com-pressive strength,thermal stability,combustion behavior,and thermal conductivity of the foam.The findings re-vealed that the bamboo powder has good compatibility and reactivity with the resin,and can be uniformly distrib-uted on the walls of the foam pores,which can strengthen the cross-linking between the substances,and pulveriza-tion rate testing demonstrated that the pulverization rate of TBF can be reduced to 2.69%.The use of bamboo powder to reinforce the tannin-based foam can effectively improve the compressibility of the foam ribs and walls,and its compressive strength(0.46 MPa)is increased by 80%compared with the standard tannin-based foam;at the same time,the bamboo powder also absorbs energy and reduces the generation and expansion of cracks.In ad-dition,TBF has been proven to be highly flame retardant in use through flame retardancy tests.关键词
