Abstract

The present invention relates to a kind of Apyre flame-proof materials, belong to technical field of refractory materials.The Apyre flame-proof material, it is made of the raw material of following mass percent: the south african andalusite of the south african andalusite 15-45%, 0.1-1mm of 1-4mm, the andalusite fine powder 5-20% of 15-45%200mesh, nano powder combines part 3-5%, the bonding clay 3-10% of 100-150 mesh.The present invention solves the problems, such as that andalusite product physical property, high-temperature behavior and thermal shock resistance existing in the prior art can decline, by introducing a variety of nanoscale micro mists in basic components, the activity of micro mist at a lower temperature is made full use of during the preparation process, strengthen the associativity of matrix and the ductile strength of product, the room temperature and high-temperature behavior of andalusite product can be improved under lower firing temperature.

Description

Apyre flame-proof material
Technical field
The present invention relates to a kind of Apyre flame-proof materials, belong to technical field of refractory materials.
Background technique
Andalusite product is due to good heat-resistant knocking stability, excellent creep-resistant property, in recent years in ceramics, smelting The high-temperature fields such as golden industry are widely used.Andalusite product generally uses import or domestic andalusite to be prepared, Due to andalusite raw material mineral structure, andalusite product can inevitably occur in high-temperature sintering process blistering, Solution cavity, blackspot and other issues are especially apparent with domestic andalusite, are commonly called as andalusite spot, this be andalusite product in the world Recognized problem, to solve the above-mentioned problems, now in the world produce andalusite product technique mainly use alumina, just The bulky grains such as jade, mullite replace andalusite bulky grain, and also some is simple by the way of reduce firing temperature, but with replacing The reduction of increase and firing temperature for ratio, the physical property of andalusite product, high-temperature behavior, thermal shock resistance can There is different degrees of decline, this directly affects the application of product, and service life is caused to reduce, serious to will cause kiln thing Therefore.
Summary of the invention
The object of the present invention is to provide a kind of Apyre flame-proof materials, solve andalusite product in high-temperature sintering process The problem of andalusite spot of appearance, product properties decline, has the characteristics that room temperature and high-temperature behavior is excellent, preparation process is simple.
Apyre flame-proof material of the present invention, is made of the raw material of following mass percent:
Wherein, the nano powder combines part and is made of the raw material of following mass percent；
The preparation method of the Apyre flame-proof material is to be uniformly mixed the raw material of formula ratio, and repressed molding is done After dry, firing, Apyre flame-proof material is obtained；Wherein, firing temperature is 1500 DEG C.
Beneficial effects of the present invention are as follows:
The present invention makes full use of micro mist to exist during the preparation process by introducing a variety of nanoscale micro mists in basic components Activity under lower temperature strengthens the associativity of matrix and the ductile strength of product, can improve under lower firing temperature The room temperature and high-temperature behavior of andalusite product.
Specific embodiment
The present invention is described further with reference to embodiments.

Wherein, the nano powder combines part and is made of the raw material of following mass percent；
The preparation method is as follows: the raw material of formula ratio is uniformly mixed, after repressed molding, dry, firing, andalusite is obtained Refractory material；Wherein, firing temperature is 1500 DEG C.Testing result is shown in Table 1.
Embodiment 2
Apyre flame-proof material is made of the raw material of following mass percent:
Wherein, the nano powder combines part and is made of the raw material of following mass percent；
The preparation method is as follows: the raw material of formula ratio is uniformly mixed, after repressed molding, dry, firing, andalusite is obtained Refractory material；Wherein, firing temperature is 1500 DEG C.Testing result is shown in Table 1.
Embodiment 3
Apyre flame-proof material is made of the raw material of following mass percent:
Wherein, the nano powder combines part and is made of the raw material of following mass percent；
The preparation method is as follows: the raw material of formula ratio is uniformly mixed, after repressed molding, dry, firing, andalusite is obtained Refractory material；Wherein, firing temperature is 1500 DEG C.Testing result is shown in Table 1.
1 testing result of table
By table 1, it can be seen that combining part by adding nano powder in formula, Apyre flame-proof material of the invention is 1400 DEG C firing in just reached the product index of even better than higher temperature firing, while solving the problems, such as andalusite spot.
