The Application Areas of a lot of thermal insulation materials, as chemical industry, machinery etc., when requiring its heat-insulating property, also to its intensity, protection against the tide, the aspects such as fire prevention have proposed composite request, therefore need the efficient energy-saving heat-insulated material of Development of Novel.
Summary of the invention
For addressing the above problem, the present invention is compound by ceramic thermal insulation fiber and brucite fiber, has obtained a kind of heat-insulation material, and described composite insulation material is to be prepared by following process by following component:
(1) take in proportion ceramic thermal insulation fiber and brucite fiber, these two kinds of fibers are put into beaker, add water and dispersion agent, soak 12 ~ 24h;
(2) regulate and stir 450 ~ 500rpm, the above-mentioned mixing of materials of soaking is even.
(3) preparation binding agent adds in the material mixing, and continues to be stirred to binding agent fiber surface is fully wrapped up.
(4) filler of sand milling being crossed adds in strong stirring container, then above-mentioned uniform slurry is added to strong stirring container, and setting stirring velocity is 1200 ~ 1300rpm, stirs 30 ~ 45min and mixes with slurry to filler.
(5) above-mentioned materials is added to die for molding, compacting, dry.
Further, described dispersion agent is sodium polyacrylate or sodium laurylsulfonate.
Further, described binding agent is that aluminum phosphate and polyvinyl alcohol mix preparation.
Further, the volume ratio of described binding agent and water is 1:2.
Further, described filler is comprised of by weight 8:1:1 pearlstone, glass bead and polyphenyl.
Further, described filler and dispersion agent weight ratio are 5:1; Filler is with fibre weight than being 1:1 ~ 1.2, and wherein ceramic fiber and brucite fiber mass ratio are 1:0.8 ~ 1; Described fiber accounts for 33 ~ 40% of total mass ratio.
