Preferably, by weight percentage by following components, comprising:
Mullite light material 52%, nodular fibrous suede 25%, Guangxi white clay 5%, Guar long bean 2%, aluminium dihydrogen phosphate liquid 8%, fine aluminium Sour 70 cement 5% of calcium, silicon powder 3%.
A kind of preparation method of high-strength heat-insulating fiber composite jetting material, comprising the following steps:
S1: spare as mixture 1 by 70 cement mixing of mullite light material, silicon powder and pure calcium aluminate；
S2: Guangxi white clay and Guar long bean are sufficiently mixed, spare as mixture 2；
S4: mixture 1 is added blender mixed grind 5 minutes, nodular fibrous suede mixed grind is added 5 minutes, is eventually adding mixture 2 Mixed grind 15 minutes, finished product.
Further, blender is added in finished product made from S3, adding aluminium dihydrogen phosphate liquid mixed grind can make for 15 minutes With.
Beneficial effect
The present invention can Rapid-Repair blast funnace hot blast stove heat waste position, have high-strength, lightweight, heat-insulated, energy saving, thermal conductivity is low, protect The advantages of temp effect is good, intensity is high, long service life.Each component of the present invention mutually cooperates with, and plays one's part to the full, wherein fine aluminium Sour calcium cement can increase high temperature intensity, and mullite light material high-temperature behavior is good, good heat insulating, and intensity is high, Guar long bean Adhesive property is good, and high temperature sintering performance is stablized, nodular fibrous suede good heat insulating, and Guangxi white clay increases high temperature intensity, improves Adhesion strength.
Specific implementation
In following embodiment, mullite light material uses the product of Yanshi light high-tech company, and nodular fibrous suede uses Beijing state The product of bold and unconstrained Chemical Co., Ltd., Guangxi white clay use the product of Guangxi Wei Luo mining industry Co., Ltd, and Guar long bean uses the U.S. The product of import, aluminium dihydrogen phosphate is using the product in education chemical plant, and pure calcium aluminate cement is using the pure calcium aluminate of Tianjin Lafarge 70 cement, silicon powder use Aitken silicon powder.In following embodiment, it is prepared according to the following steps:
(1) spare as mixture 1 by 70 cement mixing of mullite light material, silicon powder and pure calcium aluminate；
(2) Guangxi white clay and Guar long bean are sufficiently mixed, it is spare as mixture 2；
(3) mixture 1 is added blender mixed grind 5 minutes, adds nodular fibrous suede mixed grind 5 minutes, is eventually adding mixture 2 Mixed grind 15 minutes, finished product；
(4) blender is added in finished product made from step 3, adding aluminium dihydrogen phosphate liquid mixed grind 15 minutes can be used.
The additional amount that nodular fibrous suede, Guar long bean are controlled in embodiment, measures the intensity and heating conduction of spray paint.
