The conventional organic binder resin-bonded drain has the following disadvantages:
1. a plurality of antioxidant materials are required to be added, so that decarburization and oxidation are easy;
2. the mixing production equipment is more frequently cleaned, the workload is heavier, and the labor intensity of workers is increased;
3. the environment is greatly influenced by the ambient temperature and the humidity, and the environment has great limitation when used in different seasons;
4. due to the addition of the metal additive, the shelf life is limited, and the product is easy to hydrate;
5. the development trend of environmental protection requirements is carbon-free, and the resin is an organic binder;
6. free phenol and formaldehyde are contained in the resin, the resin is easy to volatilize during mixing, pollutes the environment and is harmful to the health of workers, and free water and bound water which is easy to form during the use process are contained in the resin, so that the service performance of pugs is affected, and the products are cracked after being dried; 7. the adding amount is greatly influenced by seasons, temperature and humidity, and the adding amount is large and the cost is high.
Disclosure of Invention
The invention solves the technical problem of providing a preparation process of a novel environment-friendly water outlet brick combined by modified phosphate.
The invention adopts the following technical scheme for solving the technical problems:
the preparation process of the novel environment-friendly water gap brick combined by modified phosphate is characterized by comprising the following specific steps of:
step S1, respectively weighing the following raw materials in parts by weight:
uniformly mixing the weighed 88-grade high bauxite powder or corundum powder, graphite powder, metal silicon powder, white mud, silicon carbide powder and high-temperature asphalt powder to prepare mixed powder, wherein modified aluminum dihydrogen phosphate consists of aluminum dihydrogen phosphate with specific gravity of more than or equal to 1.5, dextrin and oxalic acid;
s2, using an open wet mill or a closed wet mill or a high-speed closed wet mill to clean and mix the weighed 88-grade bauxite particles or corundum particles of the aggregate for 1-2 minutes, then adding 2-5 parts of modified aluminum dihydrogen phosphate to clean and mix for 3-5 minutes, then adding mixed powder to clean and mix for 10-15 minutes, and finally, trapping the mixed pug for 8-24 hours;
and S3, grinding the trapped pug back to mix for the second time, adding the rest modified aluminum dihydrogen phosphate, mixing for 10-15 minutes, pressing and forming into green bricks by using a press, drying, detecting to be qualified, sleeving, drying and drying.

compared with the prior art, the invention has the following advantages and beneficial effects:
1. the modified aluminum dihydrogen phosphate is an inorganic bonding agent, and the production is simple and convenient. The adhesive has a temporary bonding effect during molding, the strength is increased at about 200 ℃, and then the bonding strength shows an increasing trend along with the increase of the use temperature during the use process, and the peak value can be reached at 1250 ℃.
2. Can replace organic binder resin to play a role in temporary combination, and can meet the molding strength requirement of the semi-finished product of the sliding nozzle brick through a chemical combination mechanism.
3. In the heating process of the product combined by the modified binding agent aluminum dihydrogen phosphate, the strength is gradually and evenly improved from low temperature to medium temperature, and reaches a peak value at 1250 ℃. Before the peak value is reached, substances in the pug are subjected to in-situ sintering reaction to form crystalline phases like mullite phases, so that the strength of the product is improved, the strength of the product is in relay baton-like connection with the strength of a bonding agent, and the strength of the product is ensured.
4. The oxidation caused by the bonding agent is avoided, so that the structure is collapsed and damaged in the use process of the product; the antioxidant substances can be reduced or removed and replaced according to the needs, so that the raw material cost can be effectively reduced, and the environment-friendly requirement and the low-carbon requirement are met.
5. Has lower requirement on mixing equipment and is convenient to clean. The operability of the mixed pug is stronger than that of the resin bonded pug; is substantially zero affected by environmental factors (temperature, humidity); the bonding agent has no volatile matter, does not cause environmental protection problem, has less addition amount than resin, and is stable. Price advantage: aluminum dihydrogen phosphate (4000-4500 yuan/t), thermosetting phenolic resin (12000-13500 yuan/t).
