Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides a preparation process flow of a high-doping amount gangue industrial anticorrosive paint shown in fig. 1-2, which comprises the following steps of;
s1, preparing raw materials, wherein the raw material preparation comprises preparation of a base material and preparation of a color paste primary material, the base material preparation comprises mixing the base material with a film forming auxiliary agent, and the color paste primary material preparation comprises premixing pigment, coal gangue and the auxiliary agent;
the mass percentage of the addition of the gangue is 10% -50%, and according to the use mode of the prepared paint, the mass percentage of the gangue is 10% -20% when the paint is used as a top paint, and the mass percentage of the gangue is 20% -50% when the paint is used as a primer.
The film forming auxiliary agent comprises propylene glycol butyl ether and propylene glycol methyl ether acetate, the film forming temperature of the emulsion is generally higher, the emulsion is not easy to form a film when the ambient temperature is lower than the film forming temperature of the emulsion, the film forming auxiliary agent can improve the emulsion film forming machine and help to form a film, the film forming auxiliary agent volatilizes after film forming, the characteristic of a coating film cannot be influenced, 4% -8% of the film forming auxiliary agent is added at any stage according to the amount of the emulsion, and the film forming auxiliary agent is added in half of the film forming auxiliary agent in a grinding stage with better two adding effects, so that the wetting and the dispersing of pigment and filler are facilitated, and half of the film forming auxiliary agent in a paint mixing stage is helpful to inhibit the generation of bubbles.
The preparation of the color paste primary material comprises the steps of using auxiliary agents including dispersing agents, wetting agents and anti-settling agents.
The dispersing agent is a surfactant with two opposite properties of lipophilicity and hydrophilicity in molecules, can uniformly disperse solid and liquid particles of inorganic and organic pigments which are difficult to dissolve in liquid, and can prevent sedimentation and agglomeration of the particles to form an amphiphilic agent required for stabilizing suspension.
The wetting agent is used in the scheme to reduce the surface tension or interfacial tension of water, so that the solid surface can be wetted by the water, and the wetting agent is matched with a dispersing machine, so that all base materials can be well wetted and dispersed, and the follow-up grinding is more convenient.
The anti-settling agent is a rheology control agent of a paint, which ensures that the paint has thixotropic property and greatly improves the viscosity; the anti-settling agent plays an important role in modern paint, and has important influence on the production, storage, coating and film coating performance of the paint, so that the anti-settling agent is increasingly valued in use, and new varieties with better performance are continuously developed.
Specifically, the preparation of raw materials is completed in two steps, and firstly coal gangue, pigment, base material and solvent are mixed according to a proportion to prepare grinding color paste, so that the grinding color paste has optimal grinding efficiency; after dispersing and grinding, the other components are complemented according to the color paint formula, and then dispersing and mixing are carried out, and the components are accurately weighed according to the configuration ratio in the process of adding ingredients.
S2, performing dispersion of color paste primary materials, wherein the dispersion of the color paste primary materials is to mix the prepared coal gangue, pigment and paint, so as to realize wetting dispersion of the coal gangue and pigment;
the dispersion of the color paste primary material is carried out in a dispersion kettle, and the dispersion is carried out for 2-3 hours at the rotation speed of 800-1000rpm in the dispersion process.
The primary materials can be rapidly dispersed through stirring at a high rotating speed, but the primary materials can not be separated from the center of the dispersing kettle under the action of centrifugal force, so that the materials can be rapidly dispersed.
The equipment used for mixing and premixing is a stirring kettle, raw materials to be mixed are put into the stirring kettle, then are stirred for 1-1.5 h at the speed of 500-800r/min, and two basic materials can be fused more rapidly through high-speed stirring, and meanwhile, under the mixing, the materials are mixed more uniformly.
Influence of the dispersion of gangue and pigment in paint on the properties of the paint:
firstly, the color paint is required to be uniform in color, and if the gangue and pigment are unevenly dispersed in the paint, the color depth of a paint film is different, so that the decoration purpose is affected.
Second, gangue and pigments are solids with a higher specific gravity than paint, such as in color paints, and precipitate and agglomerate during storage.
