Problems solved by technology

[0003] In daily life, the putty powder used for building decoration is mainly made of polymer glue such as 107 glue, carboxymethyl cellulose, carboxymethyl starch, and pregelatinized starch. However, 107 glue, etc. contain formaldehyde, which is harmful to the human body. It does not meet the requirements of environmental protection. Although carboxymethyl starch and pregelatinized starch do not contain harmful substances, their cohesive force and mildew resistance are poor. After use, the putty powder is prone to mildew and falling off in wet weather. Affect the beauty of the wall

Embodiment 1

[0025] The raw materials used are: 25 kg of natural hematite powder, 35 kg of lime calcium powder, 10 kg of silicon dioxide dihydrate, 0.8 kg of cellulose, 5 kg of rubber powder, 1 kg of pigment, 0.3 kg of triclosan,

[0026] Wherein, the fineness particle diameter of natural staphilite powder is 500 orders, and the fineness particle diameter of ash calcium powder is 400 orders; Cellulose is hydroxypropyl methylcellulose, and viscosity is 50,000 mPa·s; Pigment is Phenol cyanine; rubber powder is acrylic resin;

[0027] The preparation method is:

[0028] Take the mass ratio of the required raw materials, add the natural hematilite powder, ash calcium powder and silicon dioxide dihydrate into the mixer in sequence, stir for 20 minutes and mix evenly, then add the required quality of cellulose, Put the four small ingredients of rubber powder, pigment and triclosan into the blender, and continue to stir for 10 minutes to make it fully mixed, and the product is ready.

Embodiment 2

[0030] The raw materials used are: 50 kilograms of natural hematite powder, 20 kilograms of lime calcium powder, 5 kilograms of silicon dioxide dihydrate, 1.5 kilograms of cellulose, 2 kilograms of rubber powder, 0.5 kilogram of pigment, 0.05 kilogram of triclosan,

[0031] Among them, the fineness particle diameter of natural staphilite powder is 800 mesh, the fineness particle diameter of lime calcium powder is 600 mesh; The cellulose is hydroxyethyl cellulose, and the viscosity is 60,000 mPa·s; Green; rubber powder is propylene polyvinyl alcohol rubber powder;

[0032] Its preparation method is identical with embodiment 1.

Abstract

The invention discloses sterilization moldproof aqueous putty powder and a preparation method thereof, and relates to the field of coatings. The sterilization moldproof aqueous putty powder is prepared from the following components: 25-50 parts of natural epidesmine powder, 20-35 parts of ash calcium powder, 5-10 parts of silicon dioxide dihydrate, 0.8-1.5 parts of cellulose, 2-5 parts of rubber powder, 0.5-1 part of pigment and 0.05-0.3 part of triclosan. The preparation method comprises the following steps: sequentially adding three main materials, namely, natural epidesmine powder, ash calcium powder and silicon dioxide dehydrate into a stirring machine, stirring to mix uniformly, sequentially adding four secondary materials, namely, cellulose, rubber powder, pigment and triclosan of requested mass into the stirring machine, and continuously stirring to sufficiently mix the materials, thereby obtaining the sterilization moldproof aqueous putty powder. The sterilization moldproof aqueous putty powder has the functions of sterilization, mold resistance, humidity adjustment, and air purification.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a bactericidal and anti-mildew water-based putty powder and a preparation method thereof. Background technique [0002] Putty is a kind of decorative coagulation material for leveling the surface of the wall. It is a thick paste paint and an indispensable product before the paint is painted. [0003] In daily life, the putty powder used for building decoration is mainly made of polymer glue such as 107 glue, carboxymethyl cellulose, carboxymethyl starch, and pregelatinized starch. However, 107 glue, etc. contain formaldehyde, which is harmful to the human body. It does not meet the requirements of environmental protection. Although carboxymethyl starch and pregelatinized starch do not contain harmful substances, their cohesive force and mildew resistance are poor. After use, the putty powder is prone to mildew and falling off in wet weather. affect the aesthetics of the wall. ...
