Problems solved by technology

[0002] Nowadays, most of the colored raw materials used to decorate walls on the market are paints. The paint itself has poor weather resistance after being attached to the outer wall, and it is easy to fade, and even peeling, peeling, etc., and the wall is prone to cracks and water seepage in the future. , causing the problem of poor aesthetics of the wall. Wall pigments are easy to decolorize and are not corrosion-resistant. Although they are convenient to use, they are not practical. Commonly used organic pigments are more waterproof than inorganic materials, but they are not easy to color and are not suitable for walls.
[0003] At present, in order to enhance the aesthetics of the wall, there are also some technologies for studying ready-mixed mortar for colored walls. For example, Chinese patent CN 104973827 A discloses ready-mixed mortar for colored walls. The method is to mix various materials according to the following weight ratios Mix to make color wall ready-mixed mortar: cement 15%-18%, silica fume 1%-3%, sand 70%-80%, inorganic pigment 2%-5%, cellulose ether 0.012%-0.015%, Rubber powder 1%-2%, thixotropic lubricant 0.2%-0.5%, hydrophobic agent 0.2%-0.5%, cellulose 0.3%-0.5%, the method is to add a variety of tough materials to the formula, so that the mortar surface has Extremely hydrophobic, water-repellent, waterproof, improve the effect of masking taste, and have performances such as resistance to perception and scrubbing, but the present invention uses inorganic raw materials, and many tough materials are used to easily cause secondary pollution, and the present invention does not How to disclose how to prevent corrosion and the problem that organic raw materials are not easy to color
Therefore, the present invention needs to provide a method to overcome the problems that organic raw materials are not easy to color, ready-mixed mortar is not corrosion-resistant, and environmental protection will cause secondary pollution.

Embodiment 1

[0021] Take 10% river sand with a particle size of 0.20mm, 13% quartz sand with a particle size of 0.20mm, 15% primary fly ash, 10% granulated blast furnace slag powder, 1% polycarboxylic acid, 1 % of sodium gluconate, 20% of organic pigments, 5% of redispersible latex powder, 10% of kaolin with an average particle size of 0.5-1 μm, 5% of electrolytic manganese slag waste, and 10% of cement for stirring and mixing, adding water , after the mixing mortar is viscous, apply the mixing mortar on the 3 walls of 8 cement bricks with a brick knife, with a thickness of about 2cm. After the ready-mixed mortar is formed, use tap water and 5% Na 2 SO 4 Solution and 5% NaOH solution are sprayed on the wall respectively. After 25 days, check the quality of the wall to see if there is cracking, discoloration, or falling off. If there is falling off, measure and calculate the falling off area, and test the compression resistance of the wall Strength, impermeability, shrinkage.

Embodiment 2

[0023] Take 5% of river sand with a particle size of 0.40mm, 20% of quartz sand with a particle size of 0.40mm, 10% of primary fly ash, 15% of granulated blast furnace slag powder, 2% of polycarboxylic acid, 2 % of sodium gluconate, 5% of organic pigments, 15% of redispersible latex powder, 20% of kaolin with an average particle size of 0.5-1 μm, 1% of electrolytic manganese slag waste, and 5% of cement for stirring and mixing, adding water , after the mixing mortar is viscous, apply the mixing mortar on the 3 walls of 8 cement bricks with a brick knife, with a thickness of about 2cm. After the ready-mixed mortar is formed, use tap water and 5% Na 2 SO 4 Solution and 5% NaOH solution are sprayed on the wall respectively. After 25 days, check the quality of the wall to see if there is cracking, discoloration, or falling off. If there is falling off, measure and calculate the falling off area, and test the compression resistance of the wall Strength, impermeability, shrinkage. ...

Embodiment 3

[0025] Take 7% of river sand with a particle size of 0.30mm, 10% of quartz sand with a particle size of 0.30mm, 13% of primary fly ash, 13% of granulated blast furnace slag powder, 1.5% of polycarboxylic acid, 1.5 % of sodium gluconate, 16% of organic pigments, 11% of redispersible latex powder, 17% of kaolin with an average particle size of 0.5-1 μm, 2% of electrolytic manganese slag waste, and 8% of cement for stirring and mixing, adding water , after the mixing mortar is viscous, apply the mixing mortar on the 3 walls of 8 cement bricks with a brick knife, with a thickness of about 2cm.

Abstract

The invention relates to a pre-mixed mortar material for construction, in particular to waterproof anticorrosive colorized pre-mixed mortar. The pre-mixed mortar is prepared by mixing the following materials in percentage by weight: 5-10% of river sand, 10-20% of quartz sand, 5-10% of fly ash, 5-10% of granulated blast furnace slag powder, 1-2% of polycarboxylic acid, 1-2% of sodium gluconate, 5-20% of organic pigment, 5-15% of re-dispersible latex powder, 10-20% of kaolin, 1-5% of electrolytic manganese residue wastes, and 5-10% of cement. The colorized pre-mixed mortar prepared by use of the above proportions has the characteristics of easy coloration, water resistance, and corrosion resistance when applied to decoration of wall bodies.
