preparation example Construction

[0020] The preparation method of the ceramic composite material reinforced by continuous basalt fiber comprises the following steps:

[0021] (1) Mix the calcined and refined ceramic powder according to the content ratio, add the obtained ceramic mixture to the basalt fiber particles and stir evenly;

[0022] (2) The raw powder is pressed into shape by a press, and the ceramic body is extruded and dried;

[0023] (3) It is fired in the kiln by the non-compact sintering process.

[0024] Further, the stirring time in step (1) is 10-15 minutes.

[0025] Further, the drying time in step (2) is 45-60 minutes.

[0026] Further, the firing temperature in step (3) is 1000°C to 1200°C.

Embodiment 1

[0029] Select the powder mixed with calcined and refined silica, alumina, iron oxide, calcium oxide, magnesium oxide, potassium oxide, sodium oxide, and caustic soda, and stir for 10 minutes without adding basalt fiber material. The press presses the raw powder into shape, extrudes the ceramic body, dries it for 45 minutes, and then fires it in a kiln at 1000 ° C by using a compact-free sintering process.

Embodiment 2

[0031] Select the powder mixed with silica, alumina, iron oxide, calcium oxide, magnesium oxide, potassium oxide, sodium oxide and caustic soda after calcined and refined treatment, and add basalt according to the ratio of ceramic and basalt fiber at 1:0.5 The fiber material is stirred for 12 minutes, and the raw powder is pressed into shape by a press, and the ceramic body is extruded and dried for 50 minutes, and then fired in a kiln at 1100°C by a compact-free sintering process.

Abstract

The invention discloses a continuous basalt fiber reinforced ceramic composite and preparation method for the ceramic composite, wherein the continuous basalt fiber (CBF) is compounded with ceramic, and then stirred, molded, dried and calcined to obtain the continuous basalt fiber reinforced ceramic composite. According to the invention, the advantages of CBF such as good mechanical property, high toughness, high strength, and good high-temperature resistance are fully utilized. Through the method mentioned above, the defects of low toughness, high fragileness, and easy cracking which are normal in ceramic materials are overcame. In addition, cracking is prevented and resisted, and the toughness and strength are increased so as to expand the application range of the ceramic.

Description

technical field [0001] The invention relates to the field of ceramic products and a preparation method thereof, in particular to a continuous basalt fiber reinforced ceramic composite material and a preparation method thereof. Background technique [0002] Continuous basalt fiber is a continuous fiber made of natural volcanic extrusive rock, which is crushed and put into a melting furnace, melted at 1450°C~1500°C, and then made through a platinum-rhodium alloy drawing bushing. CBF is the fourth largest high-tech fiber after carbon fiber, aramid fiber and high molecular weight polyethylene fiber. It is a new type of high-tech inorganic fiber structure and functional material. It has many unique advantages, such as: good mechanical properties, durable Good high temperature performance, can work continuously in the range of -269~700°C, acid and alkali resistance, strong UV resistance, low moisture absorption, better environmental resistance, good insulation performanc...
