Embodiment 1

[0028] 1) Powder preparation: Take 480kg of sulfoaluminate cement, 250kg of fly ash, 250kg of expanded perlite, and 20kg of sulfate according to the mass ratio, and mix them to obtain 1000kg of powder.

[0029] 2) Preparation of liquid material: Take 15kg of commercially available nonionic surfactant as foaming agent according to mass ratio, 10kg of hydroxypropyl methylcellulose, 10kg of basalt fiber as toughening agent, 20kg of methyl silicone oil, mix, Make up 1000kg with water, and pack it to get the liquid material.

[0030] When in use, the prepared liquid material and powder material are pre-foamed and stirred according to the mass ratio of liquid material: powder material = 1: 1, and then transported to the mold, then dried at a high temperature of 85°C for 2 hours, then demoulded, and transferred to the mold. Put it in the warehouse for natural conservation for 3 days.

Embodiment 2

[0032] 1) Powder preparation: Take 680kg of aluminate cement, 50kg of heavy calcium carbonate, 100kg of light calcium carbonate, 150kg of closed-cell vermiculite, and 20kg of sulfate according to the mass ratio, and mix to obtain 1000kg of powder.

[0033] 2) Preparation of liquid material: Take 10 kg of rosin soap as foaming agent, 10 kg of hydroxyethyl cellulose, 10 kg of diabase fiber as toughening agent, and 20 kg of organic silicon according to the mass ratio, mix and make up 1000 kg with water to obtain liquid material.

[0034] When in use, the prepared liquid material and powder material are pre-foamed and stirred according to the mass ratio of liquid material: powder material = 1: 1, and then transported to the mold, then dried at a high temperature of 85°C for 2 hours, then demoulded, and transferred to the mold. Put it in the warehouse for natural conservation for 3 days.

[0035] It should be noted that the above cement is selected from one or more combinations of ...

Abstract

The invention discloses an inorganic fiber reinforced cement heat preservation product. The heat preservation product comprises a liquid material and a powder material, and when the heat preservation product is used, the liquid material and the powder material are prepared into a finished product according to the weight ratio of 1: 1, wherein the powder material comprises the following raw materials in percentage by weight: 40%-68% of cement, 15%-25% of filler, 15%-25% of light aggregate and 0.5%-2% of an early strength agent; and the powder material comprises the following raw materials in percentage by weight: 1%-1.5% of foaming agent, 0.5%-1% of foam stabilizing agent, 0.5%-1.5% of toughener, 0.5%-2.5% of hydrophobic agent and the balance water. Experiments prove that, the addition of inorganic fiber can effectively improve the creasing resistance of the product and increase the toughness and the dimension stability of the product, and various indexes can meet the existing related national standards.

Description

technical field [0001] The invention belongs to the field of new building thermal insulation materials and resource recycling, and in particular relates to an inorganic fiber reinforced cement thermal insulation product. Background technique [0002] In the 21st century, energy conservation has become my country's third basic national policy after family planning and environmental protection, and is one of the fundamental requirements for building a conservation-oriented society. At present, the increase of building energy consumption in my country accounts for 27.8% of the total energy consumption. With the rapid development of the national economy, the rising trend of building energy consumption in my country is accelerating year by year. Therefore, actual building energy conservation has great significance and potential for my country's energy strategy. [0003] Energy-saving buildings are far superior to traditional buildings in terms of reducing building energy consump...
