Problems solved by technology

Although most coating preparation processes are simple now, the process has great ambiguity, so the product coatings produced are highly polluting and the cost of raw materials is also high. For example, the application number CN200610015827.5 discloses a coating preparation process , put anhydrous coal tar and anhydrous phenol oil into the heating kettle, after stirring, add polyvinyl chloride powder, dioctyl phthalate, barium stearate, after stirring, heat, add talcum powder, keep warm, Stop heating, cool down, stop stirring, the advantages of the present invention: it has weather resistance, elasticity, elongation, cohesiveness, the coating film is not brittle or cracked at low temperature, and does not flow at high temperature, but there is no well-organized process Process, clear raw material ratio, in this kind of process, only one kind of coating can be produced, which is not suitable for the development of enterprises and the improvement of enterprise benefits

Embodiment 1

[0021] A kind of coating preparation process of the present embodiment is characterized in that, its process step is as follows:

[0022] (1) Selection of raw materials: by weight percentage, polystyrene foam, phenolic foam, waste rubber and nitrocellulose account for 65%, industrial alcohol, coal tar, acetone and water solvent account for 15%, pigments and fillers account for 15%, Wetting and dispersing agents, defoamers, matting agents, and plasticizer additives account for 5%;

[0023] (2) Melt refining: the above-mentioned polystyrene foam, phenolic foam, waste rubber and nitrocellulose are mixed and melted, the temperature is controlled at 120°C to 150°C, and the base resin with high purity is extracted through filtration;

[0024] (3) Pre-scouring: In the pre-scouring tank, the pigment, base resin and solvent are stirred at a high speed to achieve a uniform exchange and a fully wet mixing state to obtain a pigment slurry;

[0025] (4) Dispersion: Grinding the pigment sl...

Embodiment 2

[0033] Embodiment 2: the rest is the same as the above-mentioned embodiment 1, the difference is that the melting temperature in step (2) is controlled at 180°C to 240°C. In this embodiment, the cost of melting is higher than that in embodiment 1, but The full melting rate is higher than that of Example 1, and the waste utilization rate is higher.

Embodiment 3

[0034] Embodiment 3: the rest is the same as the above-mentioned embodiment 1, the difference is that the filtration in step (6) and the filling in step (7) are combined, and the filtration and filling are completed on one device. In the embodiment case, the filter element filter filling machine is used, and the filtering effect is not high, but compared with embodiment 1, the operation is much more convenient and saves labor.

[0035] According to experiments, through the above coating preparation process, different high-standard and high-quality coatings can be produced according to the reasonable ratio of raw materials. The most important thing is that the white pollution and other wastes in life are reused. . Moreover, the process is reasonable and clear, which greatly improves the production efficiency. Because of its wide source of raw materials, and most of them are reused waste, the production cost is greatly reduced, and it is suitable for the needs of its production ...

Abstract

The present invention disclosed a coating preparation technology, which is characterized by the process steps: (1) Select the raw material: according to the weight percentage, 65%of the polystyrene foam, phenolic foam plastic, waste rubber and nitro fiber, industrial alcohol, Coal Coroline, acetone and water solvent accounted for 15%, pigments and fillers accounted for 15%, and 5%of moisture dispersant, elimination agent, lighting agent, plasticizer auxiliary agent; (2) melting refining;; (4) Disclosure; (5) harmonization; (6) filtering; (7) packaging; the invention is reasonable and concise, which greatly shortens the process of process.At the same time, according to the raw material ratio, coatings that are convenient for the functions of each medium, suitable for the needs of its production process, the amount and ratio of the proportion are accurate, the deviation is small, the product quality is guaranteed, and the company's output is effectively improved.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to a coating preparation technology. Background technique [0002] At present, coatings have been widely used in the construction industry, packaging materials, household daily necessities and automobiles and other fields. Paint is a chemical mixture that can firmly cover the surface of objects for protection, decoration, marking and other special purposes. With the continuous expansion of industrialized large-scale production and the continuous improvement of people's living standards, some domestic garbage and industrial waste continue to increase, which has brought serious environmental pollution to the society. Waste and old foam plastics, waste rubber and coal tar have caused serious environmental pollution. Serious "white pollution" and "black pollution" have become a worldwide public hazard, endangering people's quality of life and restricting the development of the nation...
