Example 1
Adding isothiazolinone 0.15kg, anti-settling agent (Brilliant nest partner) 1kg, stabilizer (Brilliant nest guard) 20.2kg, high-temperature bactericide 0.1kg, and pure acrylic emulsion 12kg into a stirrer, stirring for 5min at 500r/min.
The isothiazolinone can kill bacteria, fungi and other microbes in water effectively to prevent paint from deteriorating, and the anti-precipitant can prevent paint from layering and depositing solid matter, increase the transparency of paint and improve construction effect. The stabilizer is mainly composed of montmorillonite, has covering power and adhesive force, has extremely strong water absorbability and dispersibility, and plays a role of a dispersing agent in the paint, so that the paint is kept uniform. The benzisothiazolinone has the functions of corrosion resistance, mildew resistance, deterioration resistance, demulsification resistance and the like. The pure acrylic emulsion is an emulsion formed by copolymerization of various acrylic acid, methacrylic acid, methyl methacrylate, acrylic esters and functional additives through an optimized process, has no toxicity, no corrosiveness and no combustion, has high safety and environmental protection, is a base part of a coating, and is also a carrier of main coating additives such as sand stone, fluorite and the like.
0.9kg of film-forming additive, 0.5kg of ethylene glycol and 0.1kg of multifunctional additive are added into the mixed emulsion after the steps are completed, and stirring is continued for 40 minutes at the rotating speed of 500r/min.
The film forming additive is an alcohol ester compound, which is also called as a coalescing additive. Can promote the plastic flow and elastic deformation of high molecular compound, improve the coalescence property, and can form a film in a wider construction temperature range, and is a fugitive plasticizer. The general emulsion has a film forming temperature, when the ambient temperature is lower than the film forming temperature of the emulsion, the emulsion is not easy to form a film, and the film forming auxiliary agent can improve the film forming mechanism of the emulsion and help to form a film. The film forming auxiliary agent volatilizes after film forming, and the characteristic of the coating film is not affected. The glycol has hygroscopicity at the freezing point of-12.6 ℃, plays a role in preventing freezing in the paint and has a slow drying effect in construction. The multifunctional auxiliary agent is 2 amino-2-methyl-1-propanol, and has the functions of improving pigment dispersibility of the paint, improving the gloss of a paint film, regulating and stabilizing the PH value of the paint, improving the performance of a thickener and the like. The film forming additive, glycol and multifunctional additive are all paint additives for improving and improving the performance of paint.
And adjusting the pH value to 9.
The pH value of the emulsion is regulated by using a multifunctional auxiliary agent, and the emulsion is regulated by using a small amount of multiple principles.
The base material is put in, a 5mm sieve is arranged at a feed inlet of the stirrer, 4kg of fluorite (the ratio of powder to granular is 1:3) with a specified ratio, 28kg of coarse sand with 40-80 meshes and 28kg of fine sand with 80-120 meshes are sequentially put in, and the stirring is uniform.
The emulsion is prepared, so that the fluorite powder can be put in, the fluorite powder is bright in color and mixed into the emulsion, the fluorite powder is a key component of the marble-like coating, coarse sand and fine sand not only increase the hardness of the coating after construction, but also have the texture of natural stone, and can be combined with the fluorite, so that the fluorite powder can be compared with the natural marble, and the decorative effect is much better than that of the common coating.
Thickening, namely 5kg of a prepared thickening agent RD-180 (the ratio of raw pulp to water is 1:19) is put into the emulsion after the step four, and the mixture is stirred uniformly.
Defoaming, namely adding 0.05kg of defoaming agent into the thickened emulsion, stirring, eliminating foam generated in the step five, adding the defoaming agent in batches, and observing the state of the coating to obtain the skin lotion.
After the marbleized coating product is prepared according to the steps, the quality characteristics of the marbleized coating product are detected.
