Problems solved by technology

[0008] The color mortar produced by the existing order-based color separation method is difficult to achieve large-scale and continuous production and use during use. The problem of replenishment, excess products will cause product backlog and waste, and replenishment often brings about the problem of large color difference of each batch of colored mortar, which needs to be adjusted, and new tailings will be generated after replenishment
[0009] As mentioned above, there is a lack of a method for producing colored facing mortar in this field, so that the colored facing mortar has the characteristics of large-scale production and personalized color use

Abstract

The invention provides to a method for producing color facing mortar. The method comprises the following steps of: producing white dry mixed facing mortar with controllable whiteness as the base material of color facing mortar; screening color paste compatible with the white dry mixed facing mortar with controllable whiteness to be as the color-mixing paste; building the color matching proportion relationship between the white dry mixed facing mortar and the color-mixing paste, wherein the proportion relationship can be expressed as the mode of a form, the mode of a point-line diagram or the mode of a curve diagram, preferably the mode of a curve diagram; and mixing and formulating the white dry mixed facing mortar and the color-mixing paste according to the proportion relationship obtained in Step 3 to obtain the color facing mortar. Based on the method for producing color facing mortar provided by the invention, the scale production of color facing mortar can be achieved, and the method also can be used for producing color facing mortar of special colors.

Description

technical field [0001] The invention relates to a production method of mortar, in particular to a method of continuous, high-capacity, and color facing mortar with substantially consistent chromaticity between batches. Background technique [0002] Architectural coatings mainly refer to coatings used for building exterior walls, interior walls, ceilings, floors, etc., which have decorative, protective and residential performance improvement functions. Benzene substances, formaldehyde and other organic volatiles, organic solvents, and heavy metals in early paints have caused serious pollution to the environment and humans, and there is a risk of pollution in every link from production to use. With the advancement of technology and people's emphasis on pollution, the paint industry has entered the era of "water-based paint" from the "oil-based paint" era. [0003] At present, architectural coatings are mainly water-based coatings, and water-based coatings are coatings with wa...
