Abstract

The invention discloses a fiber-reinforced heat preservation and insulation material and a preparation method thereof. The material comprises 35-50 parts of polyurethane, 25-35 parts of phenolic resin, 8-15 parts of polystyrene foam plastics, 3-10 parts of ball-milled aluminum silicate, 6-12 parts of ball-milled anorthite, 6-12 parts of ball-milled calcium fluoride, 10-18 parts of zirconia ceramics fibers, 6-10 parts of copper ammonia fibers and 5-9 parts of 2-octyldodecanol. The preparation method includes the steps: (1) firstly, respectively crushing the aluminum silicate, the anorthite and the calcium fluoride by a crusher and then ball-milling the aluminum silicate, the anorthite and the calcium fluoride by a ball mill; (2) feeding the materials into a high-temperature stirrer for mechanical stirring; (3) placing mixed materials in the high-temperature stirrer into a high-temperature die for pressing to obtain the fiber-reinforced heat preservation and insulation material.

Description

technical field [0001] The invention belongs to the field of energy-saving and environment-friendly materials, and relates to a thermal insulation material and a preparation method thereof, in particular to a fiber-reinforced thermal insulation material and a preparation method thereof. Background technique [0002] Thermal insulation materials include inorganic materials and organic materials, inorganic materials include expanded perlite, aerated concrete, rock wool, glass wool, etc., organic materials include polystyrene foam, polyurethane foam, etc. The thermal insulation performance of these materials is mainly determined by the thermal conductivity of the material (the index is thermal conductivity). The more difficult the heat conduction of the material (that is, the smaller the thermal conductivity), the better its thermal insulation performance. [0003] Generally speaking, the common feature of thermal insulation materials is that they are light, loose, porous or f...
