Abstract
The invention belongs to the technical field of refractory materials and discloses a high-temperature reinforcing agent for refractory materials and a preparation method of the high-temperature reinforcing agent. The high-temperature reinforcing agent is prepared from the following raw materials in percentage by weight: 15-20 percent of synthetic mullite of which the particle size is smaller than 0.045 mm, 55-60 percent of alumina micro-powder of which the particle size is smaller than 0.045 mm, 15-20 percent of silica micro-powder of which the particle size is smaller than 0.045mm and 5-10 percent of a special additive, wherein the special additive is sodium carboxymethyl cellulose or sodium lignin sulfonate. The preparation method comprises the following steps: taking the raw materials in proportion, mixing and grinding to the average particle size of being smaller than 0.002mm. After the high-temperature reinforcing agent is added in a refractory product, the normal-temperature and high-temperature mechanical properties of the product can be greatly improved, and the high-temperature erosion resistance is superior.
Description
Technical field
The invention belongs to technical field of refractory materials, be specifically related to a kind of high temperature toughener used for refractory material and preparation method thereof.
Background technology
The bonding agent of most of aluminium silicon based article produced in the market generally uses soft clay, soft clay has certain plasticity-, adobe can be made to have certain intensity when drying, under high temperature, forming section liquid phase makes goods produce liquid phase sintering, a large amount of glassy phase is filled between goods internal particle, goods have beautiful and charming normal temperature strength, but mechanical behavior under high temperature is poor, as soft in lotus, thermal shock, the anti-folding of high temperature etc.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of high temperature toughener used for refractory material and preparation method thereof, after this high temperature toughener is added to refractory product, overcomes the problem that there is side effect when existing bonding agent uses.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is as follows:
A kind of high temperature toughener used for refractory material, is made up of the raw material of following mass percent: the mullite synthesizing 15-20% of granularity < 0.045mm, the alumina powder 55-60% of granularity < 0.045mm, the silicon powder 15-20% of granularity < 0.045mm, specialist additive 5-10%; Described specialist additive is Xylo-Mucine or sodium lignosulfonate.
In mass percentage, in mullite synthesizing: mullite phase 80-90%, Fe
2o
3< 0.8%, K
2o+Na
2o < 0.3%, Al in alumina powder
2o
3> 99%, SiO in silicon powder
2> 92%.
The preparation method of high temperature toughener used for refractory material: feeding in proportion, mixing is milled to mean particle size < 0.002mm altogether.
After product of the present invention is added to refractory product, sintering reaction can be completed under original sintering temperature, do not need improve firing temperature and cause energy dissipation and cost to raise, the high temperature toughener added at high temperature self can react in-situ preparation part mullite phase, the part mullite crystal under a small amount of liquid phase effect of high temperature added constantly is grown and is grown up, be interconnected with one another around product grain, connect mutually mainly through mullite between goods internal particle, normal temperature and the mechanical behavior under high temperature of goods can be increased substantially, and high-temperature anti-corrosion performance is more superior.Simultaneously because this high temperature toughener at high temperature generates mullite meeting with certain volumetric expansion, so this high temperature toughener can regulate add-on to control the rate of expansion of goods.
