Embodiment 1

[0028] This embodiment provides a method for processing wall paint, using coal gasification ash as the main processing raw material, the specific process is as follows:

[0029] Step 1. Primary processing of coal gasification ash: Grind the raw material of coal gasification ash to a particle size of 80 μm, mix and stir with polyacrylamide solution at a ratio of 1000:3 to obtain a mixture; add 0.3-0.5% of the total weight of the mixture. Oxygenated soybean oil, continue to stir, add an appropriate amount of deionized water, and stir to form a slurry S with a consistency of 1.5 at a stirring speed of 1200r / min; before the raw material processing of the coal gasification ash, it is necessary to control its combustion degree to exceed 99% %, the purpose is to improve the purity of the raw material of coal gasification ash, so that it can be fully burned before processing to form white ash with uniform texture;

[0030] Take 3% of kaolin, 7% of diatomite, 3% of activated carbon, 1%...

Embodiment 2

[0043] This embodiment provides a method for processing wall paint, using coal gasification ash as the main processing raw material, the specific process is as follows:

[0044] Step 1. Primary processing of coal gasification ash: Grind the raw material of coal gasification ash to a particle size of 65 μm, mix and stir with polyacrylamide solution at a ratio of 1000:5 to obtain a mixture; add 0.3-0.5% of the total weight of the mixture Oxygenated soybean oil, continue to stir, add an appropriate amount of deionized water, and stir to form a slurry S with a consistency of 1.4 at a stirring speed of 1300r / min; before the raw material processing of the coal gasification ash, it is necessary to control its combustion degree to exceed 99% %, the purpose is to improve the purity of the raw material of coal gasification ash, so that it can be fully burned before processing to form white ash with uniform texture;

[0045] Take 5% of kaolin, 4% of diatomite, 5% of activated carbon, 0.5...

Abstract

The invention relates to the technical field of process of wall paint. In particular to a processing method for wall paint. The processing method for the wall paint comprises the steps of taking coalgasification ash as a main processing raw material, grinding the coal gasification ash until the granularity is less than or equal to 80 mu m, uniformly mixing and stirring the raw material a polyacrylamide solution according to the ratio of 1000: 3-5 to obtain a mixture, then processing the mixture into slurry S, mixing and processing the slurry, kaolin, diatomite, activated carbon, clay and talcum powder to obtain slurry M, mixing and curing and then drying and grinding to obtain fine coal gasification ash, and mixing and processing the fine coal gasification ash with deionized water, titanium dioxide and an auxiliary material to obtain the safe and environmentally friendly wall paint. Secondary utilization of the coal gasification ash is realized, the waste coal gasification ash is changed into things of value, natural ore resources are saved effectively, and the utilization rate of the resources is increased.

Description

technical field [0001] The invention relates to the technical field of wall paint processing, in particular to a processing method of wall paint. Background technique [0002] Wall paint is top paint, also known as latex paint, which is one of the main decorative materials used for walls in home decoration. It accounts for a considerable proportion of the cost of basic decoration. It is very important to choose high-quality wall paint. In order to achieve the purpose of bonding, the main component of wall paint is formaldehyde, which can be firmly bonded to the wall. In my country, it is customary for people to use synthetic resin emulsion as the base material, use water as the dispersion medium, add pigments, fillers (also known as body pigments) and additives, and the paint made through a certain process is called latex paint, also called latex. coating. [0003] Household decoration pollution refers to the pollution caused by harmful gases released by various building ma...
