Low-thermal-conductivity thermal insulation material and preparation method thereof
The invention discloses a low-thermal-conductivity thermal insulation material and a preparation method thereof. The low-thermal-conductivity thermal insulation material is prepared from the followingraw materials of, in parts by mass, 60 parts-70 parts of fumed silica; 10 parts-20 parts of common silica; 10 parts-15 parts of silicon carbide, and 5 parts-10 parts of fibers. The fumed silica and the common silica are combined for use, so that the characteristics of good thickening property and difficulty in moisture absorption of the fumed silica can be exerted, meanwhile, the characteristic of polyhydroxyl of the common silica can be exerted, the fumed silica can be better compounded with the fibers, and the moisture absorption characteristic can be inhibited due to the low content of thefumed silica; and the silicon carbide has radiation resistance and wear resistance, the silicon carbide is used as an intermediate substance in the thermal insulation material, and the fumed silica,the common silica and the fibers are filled in the silicon carbide, so that the silicon carbide has relatively high strength on the premise of ensuring a low heat conductivity coefficient.
一种低导热率隔热材料及其制备方法，包括如下质量份数的原料：气相白炭黑：60‑70份；普通白炭黑：10‑20份；碳化硅：10‑15份；纤维：5‑10份。本申请采用气相白炭黑、普通白炭黑进行结合使用，使得可以发挥出气相白炭黑增稠性好，不易吸湿的特点，同时还能够发挥出普通白炭黑具有多羟基的特性，可以与纤维进行更好的复合，但是其低的含量又能把吸湿的特性抑制住；而碳化硅则是具有抗辐射和耐磨性能，碳化硅本身在隔热材料中作为中间物质，气相白炭黑和普通白炭黑以及纤维充填其中，使得能够在保证低的导热系数的前提之下，具有相对较高的强度。
