Embodiment 1

[0012] Example 1 Raw material weight ratio: silicon dioxide: aluminum oxide: magnesium oxide = 55:40:4; the raw material is melted at 1700-1900°C, and at 1550-1700°C, it is formed into fibers by blowing or centrifugal spinning process The ceramic fiber is made, the fiber performance is slightly acidic, its pH is about 6.1±, and the non-fibrous matter (slag ball) is less than 8%; after collecting cotton, it is needled into a blanket, and the needled blanket blank passes through 700-900°C The high temperature is shaped into a blanket, and the ceramic fiber needle-punched blanket with soft texture is obtained by cutting. Because the raw material is easy to obtain and its melting temperature is low, the product cost is low, which is beneficial to popularization and application of the product.

Abstract

The present invention belongs to a refractory heat-insulating material, and relates to an environment-protecting ceramic fibre needle-punched carpet and its preparation method. Its raw material silicon dioxide and aluminium oxide are undergone the processes of melting and fibre formation to obtain ceramic fibre, said ceramic fibre is undergone the processes of collecting, needling, heat treatmentand cutting so as to obtain the invented ceramic fibre needle-punched carpet. It is characterized by that its composition also contains 4-6 portions of magnesium oxide and / or calcium oxide, and its fibre-forming process adopts the blowing or centrifugal spinning process. Said fibre is stable in quality and high in yield rate.

Description

technical field [0001] The invention belongs to fire-resistant and heat-insulating materials, and is a high-temperature-resistant inorganic fiber (for example, aluminum silicate ceramic fiber) blanket, in particular to an environment-friendly ceramic fiber needle-punched blanket and a preparation method thereof. The invention is a high-temperature textile fiber that can be used at a temperature of 900-1100°C and has excellent textile performance, and is suitable as a raw material for heat-insulating fiber textiles for equipment and pipelines. Background technique [0002] Traditional ceramic fiber (aluminosilicate ceramic fiber) products, the main component of which is Al 2 o 3 and SiO 2 , the two account for about 97%, and the remaining 3% are potassium, sodium, iron, etc., and the melting temperature is greater than 2000 ° C; due to the production of spinning or blowing methods, and the fine fibers (3 ~ 5 μm), resulting in the production process.
