摘要

By orthogonal experiment design, three kinds of thermal insulation functional fillers A,B,C have been mixed with the matrix according to the orthogonal proportion.To obtain high-efficient thermal insulation composites,the thermal performance and mechanical properties were investigated to get the best proportion,and the insulation mechanism has been analyzed.The results indicate that the thermal insulation filler can reduce the thermal conductivity of composites effectively,and the thermal insulation performance is the best when the contents of A,B and C are 3%,5% and 20% by weight,respectively.The thermal conductivity of composites is as low as 0.056 W/(m•K),which is 69.6% lower than the matrix (the thermal conductivity of the matrix is 0.184 W/(m•K)).In addition,the thermal stability of the material has also been improved. The thermal decomposition temperature of the composites is 508 ℃,which is 32 ℃ higher than that of the matrix. However,the mechanical properties of the composites was decreased,the tensile strength and tear strength are 1.712 MPa and 13.219 N/mm,respectively.Furthermore, the mixture of the high-efficient thermal insulation composites and HNIW measured by DSC,indicating that the compatibility between them is good.
