Method for producing coating

Abstract

The production method of coating compound includes the following steps: placing the liquid material into a liquid material buffer feeding cylinder, opening vacuum pump to evacuate the dispersion emulsifying grinding still to negative pressure, opening liquid material feeding valve and feeding the liquid material into the dispersion emulsifying grinding still, the closing the liquid material feeding valve, adding adjuvant, opening powder material feeding valve and adding pigment anjd filling material, then closing valve and vacuum pump, dispersing for 20 min., starting basket sand mill and pipeline multi-stage wet grinder for about 20 min., stopping basket sand mill, dispersing machine and high shear emulsifying machine, closing reflux valve, opening vacuum pump to negative pressure and opening emulsion feeding valve, adding pigment and adjuvant, regulating pH value, filtering and barrelling to obtain the invented product.

Description

technical field [0001] The invention relates to a coating production method. Background technique [0002] At present, the traditional coating production method is composed of steps such as metering, dispersing, grinding, stirring, filtering, and packaging. The combination of production equipment is linear, and various equipment are arranged in a line. This method is convenient for management and maintenance of equipment, but With the expansion of production scale, the improvement of process control requirements and the increase of product types, this form has the following disadvantages. (1) The production process is scattered, which is not conducive to continuous mechanized production and increases the labor intensity of workers. (2) In the production process The airtightness of the product is poor, the product quality is affected by the environment, the transmission distance in production is long, resulting in the waste of transmission energy, (3) the process is not conce...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the paint production method in the prior art is composed of steps such as metering, dispersing, grinding, stirring, filtering, and packaging. The combination of production equipment is linear, and various equipment are arranged in a line. Management and equipment maintenance, but with the expansion of production scale, the improvement of process control requirements and the increase of product types, this form has the following disadvantages: (1) The production process is scattered, which is not conducive to continuous mechanized production and increases the labor intensity of workers , (2) The airtightness in the production process is poor, the product quality is affected by the environment, and the transmission distance in production is long, resulting in a waste of transmission energy. (3) The process is not concentrated, making production monitoring difficult, and the quality is affected by the artificial factors of workers impact, the stability of the production process cannot be guaranteed, and it is impossible to realize the problem of full automatic control of the production process
