Embodiment 1

[0028] Produce 100 kilograms of powdered anti-cracking additives, then 50 kilograms (5 parts by weight) of epoxidized octadecyl-conjugated triene-9,11,13-acid triglycerides, 20 kilograms (2 parts by weight) of lignocellulose , 20 kilograms (2 parts by weight) of 2-hydroxyethyl methacrylate and 10 kilograms (1 part by weight) of dibutyltin dilaurate are put into the mixer and dry mixed evenly (mixed for about 20 minutes) to form the anti-cracking additive.

[0029] To produce 500 kg of thermal insulation dry-mixed mortar base product of the present invention, 300 kg of red mud and 30 kg of rare earth powder are added with water to form a slurry, and a non-volatile acid solution is added to adjust the pH value of the slurry to 7-8 Dry and grind the powder to obtain powder, and mix the powder with 50 kg of limestone, 30 kg of rare earth powder, 50 kg of redispersible rubber powder, and 40 kg of powdered anti-cracking additive to form a finished product.

Embodiment 2

[0031] Produce 128 kilograms of powdered anti-cracking additives, then respectively 80 kilograms (10 parts by weight) of epoxidized octadecanoconjugated triene-9,11,13-acid triglycerides, 24 kilograms (3 parts by weight) of lignocellulose ), 16 kilograms (2 parts by weight) of 2-hydroxyethyl methacrylate and 8 kilograms (1 part by weight) of dibutyltin dilaurate are put into the mixer and dry-mixed (about 20 minutes) to form a finished product.

[0032] To produce 500 kg of thermal insulation dry-mixed mortar base product of the present invention, 250 kg of red mud and 50 kg of rare earth powder are added with water to form a slurry, and a non-volatile acid solution is added to adjust the pH value of the slurry to 7-8 Dry and grind the powder to obtain powder, and mix the powder with 50 kg of limestone, 50 kg of rare earth powder, 50 kg of redispersible rubber powder, and 50 kg of powdered anti-cracking additive to form a finished product.

Embodiment 3

[0034] The thermal insulation dry-mixed mortar base material product obtained in embodiment 1 and embodiment 2 is made into a thermal insulation board with the same specification and size as the existing sales thermal insulation board, and its thermal insulation performance is tested. The test process is as follows:

[0035] Place three insulation boards evenly on the edge of a circular test board, and place continuous burning fireworks in the middle of the circular test board, and test the inner and outer wall temperatures of the three insulation boards every 10 minutes.

[0036] The final thermal insulation performance test results are shown in Table 1.

Abstract

The invention relates to the field of thermal insulation mortar and provides a thermal insulation dry-mixed mortar base material and a preparation method thereof. The method includes: adding red mud and half of rare earth powder into water to form slurry, adding nonvolatile acid liquid for adjusting a pH value of the slurry to 7-8, drying and grinding into powder for standby application; well mixing limestone powder, dispersible adhesive powder, powdery anti-cracking additives, the other half of rare earth powder and red mud and rare earth powder mixed powder obtained at the above step to obtain the thermal insulation dry-mixed mortar base material. Effective red mud utilization is realized, and two technical problems including inadequacy in red mud comprehensive utilization and failure of existing thermal insulation dry-mixed mortar base materials in meeting of people's requirements are both solved. When water is added, gas is generated by reaction of Y2O3, La2O3, Sm2O3, La2O3 and Fe2O3 in the rare earth powder and components such as CaO in limestone to form closed air pores, so that thermal plates made from the thermal insulation dry-mixed mortar base material are provided with uniform closed air pores which form uniform thermal insulation cavities, and excellent thermal insulation performances are achieved.

Description

technical field [0001] The invention relates to the field of thermal insulation mortar, in particular to a thermal insulation dry-mixed mortar base material and a preparation method thereof. Background technique [0002] The main component is Al 2 o 3 , SiO 2 In the process of preparing aluminum hydroxide from coal gangue and fly ash, a large amount of red mud will be produced, but in actual production, many years of actual production have found that the ratio of aluminum to silicon is lower than 3:1 or even lower than 2:1 If the production of low-grade aluminum ore is carried out with such a ratio, the recovery rate of aluminum will be low and the production efficiency will be low. High-grade bauxite, so that it cannot be developed and utilized; at the same time, under the premise of high silicon content, the high calcium ratio of auxiliary materials leads to the production of more red mud. At the same time, due to the addition of a large amount of alkaline substances, t...
