摘要/Abstract

摘要： 以高模数硅酸钾溶液为基料,氧化铝为导热绝缘填料,加入硅丙乳液、消泡剂,制备有机无机复合硅酸盐导热绝缘涂层。通过测试硅酸盐涂层的导热系数、体积电阻率、孔隙率、孔径分布和元素分布变化,研究绝缘硅酸盐涂层导热性能。结果表明,适当提高氧化铝的质量分数,硅酸盐绝缘涂层的导热性能提升。氧化铝填料球形形貌和大粒径更有利硅酸盐绝缘涂层的导热性能提升。当填料为粒径2.9 μm的球形氧化铝,且质量分数在37.5%时,涂层的导热系数最高达1.072 W/(m·K),体积电阻率大于10⁸ Ω·m,此时涂层的导热绝缘性能达到最佳。

Abstract: Organic and inorganic composite silicate thermally conductive insulating coatings were prepared by using high modulus potassium silicate solution as a base material, alumina as a thermally conductive insulating filler, and silica-propylene emulsion and defoamer. The heat conduction behavior of insulating silicate coatings was studied by testing the thermal conductivity, volume resistivity, porosity, pore size distribution and elemental distribution changes of silicate coatings. The results show that the thermal conductivity of silicate insulating coatings is enhanced by appropriately increasing the mass fraction of alumina. The spherical morphology and large particle size of alumina filler are more favourable for the improvement of thermal conductivity of silicate insulating coatings. When the filler is spherical alumina with particle size of 2.9 μm and its mass fraction is 37.5%, the thermal conductivity of coating is up to 1.072 W/(m·K), the volume resistivity is more than 10⁸ Ω·m, and the thermal conductivity and insulating performance of coating reaches the best.
