Embodiment 1

[0018] ①, Potassium hexatitanate whiskers and water were weighed and mixed in a weight ratio of 100:0.5, stirred thoroughly and evenly, and left to soak for 30 minutes to become the soaking raw material;

[0019] ② Weigh and mix the above impregnation raw materials and silica sol in a ratio of 100:45 by weight, and stir fully and evenly to become raw materials for billet making;

[0020] Or, after diluting the water and the coupling agent in a weight ratio of 25:1, then mixing with the above-mentioned impregnating raw materials in a weight ratio of 100:20, and fully and uniformly stirring, to become the billet-making raw material;

[0021] ③Put the raw materials mentioned above into a wooden or steel mold, and use a 100-ton friction press to press the mold blank. The mold blank can be demoulded when the volume density is 1.5g / cm3, and then the demoulded mold The blank is placed in a drying room at 80°C to dry and dehumidify, so that its moisture content is ≤13% and becomes a m...

Abstract

The invention discloses a manufacturing method of a potassium hexatitanate whisker high-temperature thermal insulation material, comprising the following steps of: mixing potassium hexatitanate whiskers with silica sol or a coupling agent, filling into a die, compacting into a moulded die blank, demoulding and drying, and placing into a high-temperature kiln for baking to obtain the finished product. The whole technological process is simple without pollution. According to the invention, specific excellent properties of the potassium hexatitanate whisker material such as high-temperature resistance, hydrochloric acid corrosion resistance, high mechanical strength, low coefficient of thermal conductivity and significant infrared reflectivity are well-maintained. The potassium hexatitanate whisker high-temperature thermal insulation material manufactured by the method is a thermal insulation material which has excellent quality as well as extensive applications.

Description

technical field [0001] The invention belongs to a method for manufacturing a new type of thermal insulation material by using potassium hexatitanate whiskers of inorganic salt whiskers Background technique [0002] There is a calcium silicate board, which is a hard thermal insulation material. The main components are silicon powder and calcium powder as the main base material, natural wood fiber as the reinforcement material, and other auxiliary materials. A building material produced by high pressure curing, which can be produced in various shapes through molds. [0003] There is also a kind of ceramic fiber cotton, which is made of high-purity alumina silica powder synthetic material, melted in a resistance furnace, blown or spun into fibers. It is a kind of soft material, which can be attached to the outside of the object to be insulated by mechanical bending to form an insulation layer. [0004] The disadvantages of the above two building materials are that the surface...
