Problems solved by technology

The disadvantage of this granulation process is that it is difficult to control the stability of suspended particles between batches of liquid granite, and it is also impossible to effectively control the fullness and shape of particles stably
The second is through manual sieve granulation. Although this kind of granulation can effectively control the stability between batches of the same type of liquid granite, it requires a lot of manpower and material resources, and the production cost is high, and it cannot effectively meet the requirements of large batches. mass production needs

Embodiment 1

[0023] First, fully mix the prepared dispersed phase and the dispersed medium, that is, stir and mix the dispersed phase and the dispersed medium evenly.

[0024] Next, the mixture is extracted into a cutting-style rotary dispersing tank and cut by the rotary cutting blades provided in the cutting-style rotating dispersing tank.

[0025] Because the cutting of the base paints of various colors is realized by the rotary cutting blades arranged in the rotary dispersion cylinder of the cutting pattern, the rotation speed of the rotary cutting blades has a great influence on the cutting. That is, under vacuum conditions, when the rotation speed of the rotary cutting blade is adjusted to 90 rpm, the stability of the filtered particles can be well guaranteed.

[0026] After this cutting step, the stability of the filtered particles can be guaranteed.

[0027] Then, the cut material is extracted and filtered through a loading and unloading sieve;

[0028] Because the size, plumpnes...

Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the rotation speed of the rotary cutting blade is 60 rpm, the pressure for extracting the cut material is 0.04Mpa, and the number of loading and unloading sieves is 2.

Embodiment 3

[0033] The difference between this embodiment and Embodiment 1 is: the rotation speed of the rotary cutting blade is 80 rpm, the pressure for extracting the cut material is 0.05Mpa, and the number of loading and unloading sieves is one.

[0034] According to the coating preparation process adopted in the above embodiments, especially through cutting and filtering by the rotary cutting blades arranged in the rotary dispersion cylinder of the cutting pattern, the filtered material is introduced into the mixing cylinder and mixed evenly with the emulsion and additives, The two cylinders are used together, and the vacuum extraction process is used to granulate to form a stable color particle dispersion system, which ensures the stability of particle size and shape between different batches.

[0035] After testing, the particle size and shape stability of the above three examples are higher than those of weather-resistant liquid granite coatings prepared by conventional methods, and...

Abstract

The invention relates to a production technology of a coating, particularly a production technology of a weather-resistant liquid granite coating. The invention solves the problems of difficult control of the stability of suspended particles among various batches of liquid granite, unstable effective control of the plumpness and shapes of particles, great investment in human and materials, high production cost and the like. The technology comprises the following steps: mixing dispersed phases and dispersed mediums, putting the mixture in a cutting rotary scattering cylinder to cut, extracting and filtering the mixture, and introducing in a mixing cylinder to mix with emulsion and auxiliary agents and stirring. The invention can guarantee the size and shape stability of the particles among various batches, and has the advantages of small investment in human and materials, low production cost and the like.

Description

technical field [0001] The invention relates to a coating preparation process, in particular to a weather-resistant liquid granite coating production process. Background technique [0002] Existing commonly used liquid granite coating is colorful coating. Colorful coatings are generally divided into four types: oil-in-water type, water-in-oil type, oil-in-oil type, and water-in-water type. Because the oil-in-water type colorful paint adopts nitrocellulose and a large amount of organic solvents, a large amount of harmful gas is released during production and use, pollutes the environment, and causes many harms to production and users. In view of the shortcomings of oil-in-water type colorful paints and people's demand for colorful paints, new water-based colorful paints have emerged. The coating not only has most of the advantages of the oil-in-water type multi-color coating, but also overcomes the shortcoming of using organic solvents in the oil-in-water type multi-color c...
