Problems solved by technology

Due to the small amount of Mortar King, in order to diffuse the cement in the mortar, a large amount of foaming agent is used, so as to achieve the plasticity of the mortar and the softness in practical use, and reduce the amount of cement. Decreased adhesion, empty shells and shedding phenomena, seriously reducing the strength of mortar, worse earthquake resistance, poor water retention, inconvenient construction, construction workers are reluctant to use

Embodiment 1

[0022] Based on the percentage of the total weight of the raw materials, 70% of the limestone with a Mohs hardness greater than 4 and 30% of the dry white mud clay with a water content of less than 5% are ground to 300 mesh with a Raymond machine, respectively. Mix evenly, add 200,000 viscosity hydroxypropyl methylcellulose (HPMC), the amount accounts for 0.005% of the total weight of limestone and dry white mud clay; add the mixture of sodium abietate and sodium lauryl sulfate, the amount accounts for limestone and 0.001% of the total weight of dry white mud clay, the mass ratio of sodium rosinate and sodium lauryl sulfate is 1:1; adding cement instant solvent aluminum titanate, the amount accounts for 1% of the total weight of limestone and dry white mud clay 0.001%, stir well, that is.

Embodiment 2

[0024] According to the percentage of the total weight of raw materials, 60% of shale with Mohs hardness greater than 3.5, 20% of dry common red mud clay with a water content of less than 5%, and 10% of coal ash were used respectively with mine Grind to 300 mesh and then mix evenly, add a mixture of 200,000 viscosity hydroxypropyl methylcellulose (HPMC) and polyacrylamide (PAM), the amount accounts for 0.007% of the total weight of shale and dry ordinary red mud clay %, the mass ratio of hydroxypropyl methylcellulose and polyacrylamide is 2:5; add a mixture of sodium abietate and sodium lauryl sulfate, and the amount accounts for 0.001 of the total weight of shale and dry common red mud clay %, the mass ratio of sodium rosinate and sodium lauryl sulfate is 1:1; add cement instant solvent aluminum titanate, the amount accounts for 0.001% of the total weight of shale and dry common red mud clay, and stir evenly to obtain .

Embodiment 3

[0026] According to the percentage of the total weight of raw materials, take 80% of the weathered stone with a Mohs hardness greater than 3.5 and 20% of the dry common red mud clay with a moisture content of less than 5%, and grind them to 300 mesh with a Raymond machine Mix evenly again, add a mixture of 200,000 viscosity hydroxypropyl methylcellulose (HPMC) and polyacrylamide (PAM), the consumption accounts for 0.007% of the total weight of weathered stone and dry common red mud clay, hydroxypropyl methylcellulose The mass ratio of base cellulose and polyacrylamide is 3:4; Add the mixture of sodium abietate and sodium lauryl sulfate, the consumption accounts for 0.001% of the total weight of weathered stone and dry common red mud clay, sodium abietate and The mass ratio of sodium lauryl sulfate is 1:1; adding cement instant solvent aluminum titanate in an amount of 0.001% of the total weight of weathered stone and dry ordinary red mud clay, stirring evenly, and the product i...

Abstract

The invention relates to a production method of an environment-friendly plaster powder. The method is as below: mixing and grinding 2-98 wt.% of stone and 2-99 wt.% of dry clay to 150-3000 mesh, or respectively grinding and then mixing, adding a thickening agent, a foaming agent and a cement fast solvent, and stirring evenly to obtain the plaster powder. The plaster powder has the advantages of good viscosity, high hardness, convenience for construction, low cost, no decomposition in water and certain sedimentation and stability.

Description

technical field [0001] The invention relates to a method for preparing an environmentally friendly ash powder, which belongs to the field of building materials. Background technique [0002] The production and use of traditional lime paste is relatively complicated. It needs to be calcined at 900-1100°C by calcining minerals with high calcium carbonate content such as limestone and dolomite, which requires a lot of firewood, coal, oil or natural gas and other resources. A large amount of carbon dioxide, sulfur dioxide and other exhaust gases pollute the air. [0003] Mortar King is a catalyst for cement, mainly composed of two components: 1. Entraining gas (foaming agent), 2. Thickener. Due to the small amount of Mortar King, in order to diffuse the cement in the mortar, a large amount of foaming agent is used, so as to achieve the plasticity of the mortar and the softness in practical use, and reduce the amount of cement. Decreased adhesiveness, empty shells and shedding ...
