The existing products used in the field are more, and the market is commonly named as wall fixing and ground fixing. If the wall is fixed, a wall curing adhesive is an interface treatment material, and has better effect on the aspects of making a base layer compact, improving the interface adhesive force, improving the adhesive strength of mortar or putty and the surface of a wall body and preventing hollowing, but still has certain defects: 1. the adhesive strength is still insufficient; 2. does not have the function of anti-mildew and moisture-proof; 3. the cost is high; 4. the requirements on construction environment and temperature are high. For example, the cement floor curing agent is a high molecular polymer, can permeate the cement floor, has certain capability of blocking loose particles of the cement floor, can enable floor tiles or floors to be well combined with the floor, and can well prevent the floor from hollowing. These products, while numerous, are ubiquitous and still lack sufficient bond strength; does not have the function of anti-mildew and moisture-proof; the cost is high; the requirement on construction environment and temperature is high. Because the pH value (7.5-8.5) of the products is greatly different from the pH value (12-13) of the mortar concrete, the products are poor in compatibility, the treated ground or wall still has good hydrophilicity, and a large amount of water can be absorbed to the inner layer after the products are contacted with water, so that the phenomena of wall surface mildewing and ground surface moisture regain can easily occur, and the problems are troublesome and serious for the life and work of people, and the products are a general problem which needs to be solved urgently in real life.

An anti-mildew and moisture-proof agent mainly used for ground comprises the following components by weight percent: 0.1-0.9% of iron oxide yellow with the content of 95%; 8-15% of iron oxide green with the content of 96%; 5-15% of modified silicate solution with the concentration of 45%; 30-60% of waterborne epoxy resin with the concentration of 95%; 10-20% of acrylic emulsion with the concentration of 96%; 0.9 to 3 percent of color paste with the concentration of 99.9 percent; 7-15% of heavy calcium carbonate with the content of 95%; isothiazolinone 0.01-1% with concentration of 99%; 15-30% of water.
3. The preparation method of the mildew-resistant and moisture-proof agent is characterized by comprising the following steps:
firstly, mixing the waste for producing silane and water according to the weight ratio of 1:1, stirring for 1-2 hours at room temperature, and filtering to obtain 65-70% of alkyl silicic acid.
Secondly, adding 20-30% alkali solution into a reaction kettle, heating to 85-95 ℃, controlling the stirring speed to be 1000-2000 r/minx, slowly adding 65-70% alkyl silicic acid and 30-40% silicic acid according to the weight ratio of 3.5-4.5: 0.5-1.5, reacting for 1-2 hours after the dropping is finished, adding silicon dioxide with the weight percentage of less than 30 nanometers according to 0.8-1.2%, and keeping the temperature at 90 ℃ for 1 hour to obtain the modified silicate solution.
Thirdly, preparing a finished product
⑴, slowly adding the obtained modified silicate solution, the iron oxide yellow, the acrylic emulsion, the isothiazolinone and water into the reaction kettle according to a determined proportion, slowly adding the water-based epoxy resin under rapid stirring, and stirring for 2-3 hours to obtain a finished product mainly used for the wall surface.
⑵, putting the obtained modified silicate solution, iron oxide yellow, iron oxide green, acrylic emulsion, color paste, isothiazolinone and water into a reaction kettle according to a certain proportion, slowly adding the water-based epoxy resin and the ground calcium carbonate respectively under the condition of rapid stirring, and stirring for 2-3 hours to obtain the finished product mainly used for the ground.
