technical field

The invention relates to the technical field of color pigment preparation, in particular, to a preparation method of an energy-saving environment-friendly pigment.

Background technique

As an integral part of painting, painting pigments are an important part of painting art. Different materials show different artistic languages in painting works and produce different visual effects. In recent years, with the development of industrial technology, new painting materials continue to emerge. New materials advance the art of painting and support the artist's infinite exploration of work styles and painting techniques. Through the perfect combination of materials and the amazing performance of skills, a new visual language is created, making the work more expressive and artistic.

Lacquer painting is a fine product made by traditional handicrafts accumulated by the Chinese nation for thousands of years. It integrates the advantages of traditional art and modern handicrafts. "The organic combination makes the created paintings have the characteristics of bright tone, deep depth, strong three-dimensional effect, smooth and bright surface, etc. However, some existing lacquer paints contain formaldehyde, which is toxic to a certain extent. If used for a long time, it will adversely affect the body of the painter and cannot meet the actual needs.

The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.

SUMMARY OF THE INVENTION

The invention provides an energy-saving environment-friendly color pigment and a preparation method thereof. The raw material components are mixed in an appropriate ratio and used according to the steps and process conditions disclosed in the invention to obtain artworks with irregular patterns. The manipulation of color pigments and lacquer works prepared according to the present invention can be realized by the hands of an artist based on experience, and can also be produced in an industrialized manner by utilizing modern industrial technology, and the production methods are various. The invention solves the problems of fusion and penetration of color pigments, not only changes the integration of various color pigments, but also makes the colors purer, more saturated, and more splendid, provides colorful colors for the world, and adds artistic charm.

Specifically, the preparation of energy-saving environment-friendly color pigments in the present invention adopts the following technical solutions:

S1. Add 46-58 parts by mass of titanium oxide, 10-12 parts by mass of nickel oxide, 0.78-0.82 parts by mass of barium molybdate, 3-5.4 parts by mass of alumina, and 3.2-5.5 parts by mass of oxide Chromium, 1.1-2.3 parts by mass of potassium soil, 0.8-1.3 parts by mass of magnesium carbonate, and 0.6-1.1 parts by mass of sodium carbonate are ground into a mixture with a particle size of less than 10 microns by ball milling;

S2. Add 60-70 parts by mass of synthetic paint to the configuration container, and use an ultrasonic instrument to vibrate and stir;

S3. Distribute the fully vibrated and stirred mixture into different sub-containers, add a certain mass of organic mineral coloring powder to the sub-containers respectively, and continue to use an ultrasonic instrument to vibrate and stir to form coloring pigments of different colors. ;

S4. Add a certain amount of diluent to the coloring pigments of different colors according to painting requirements, and the diluent is linseed oil or olive oil.

In addition, the present invention also discloses a preparation method of an energy-saving and environment-friendly color lacquer painting, using the color pigment prepared by the above-mentioned preparation method, further comprising taking the following steps:

S5. Provide a panel of a certain size according to the size of the painting, perform waterproof treatment on the panel, apply rabbit skin glue and water evenly to the panel two to three times in a certain proportion, and use a microwave instrument after each application of the glue. drying treatment;

S6. Brush white polyester paint on the panel as a primer, and use a microwave to dry completely;

S7. Fix the panel on the back panel, drip or spray or pour the prepared color pigments of one or more colors into part of the panel area, and guide the color pigments to flow and blend into a design shape, forming a lacquer painting;

S8. Stand at room temperature for 36-48 hours, and after it is completely dry, remove the lacquer from the backing plate and mount it.

Preferably, the organic mineral colored powder is selected from cobalt oxide, copper oxide or iron oxide. Different applications of pigments also have a certain influence on the adhesion of pigments. In the experiment, we found that the change of the amount of different pigments has a significant impact on the adhesion. For example, when the pink pigment increases from 4% to 12%, the adhesion is basically stable; melanin, cyan pigment, coffee pigment, and green pigment are beneficial to the adhesion. , so its content can be increased; while yellow pigments, orange-red pigments, etc. are harmful to adhesion, so it is necessary to reduce their content. Through comparative experiments, the organic mineral colored powder of the present invention is selected from cobalt oxide, copper oxide or iron oxide which are environmentally friendly and have high adhesion.

Preferably, the thickness of the primer layer is 6-8 mm.

Preferably, the ultrasonic frequency of the ultrasonic instrument is 3 MHz.

Preferably, the microwave power of the microwave instrument is 600-800W, the microwave frequency is 2.45GHZ, and the microwave processing time is 60s.

Traditional color pigments have gas defects in the preparation process, especially bubbles are a difficult problem in pigment preparation. Due to processes such as stirring, part of the cementite in the pigment is decomposed, and gases such as carbon dioxide escape, resulting in the gloss and continuity of the pigment. Poor sex. In view of such defects, in the specific operation process of the present invention, it is first necessary to reasonably reduce the surface tension of the pigment formulation. Specifically, carbonic acids such as MgCO ₃ , Na ₂ CO ₃ , CaCO ₃ , BaCO ₃ and the like are simultaneously introduced into the mill adduct. One or more salts so that they provide gradient clarification of the pigment during the compounding process.

In the manufacturing process of lacquer painting, adding an appropriate amount of diluent can save the preparation before painting, and using linseed oil or olive oil as diluent can achieve more environmental protection and energy saving effect. The choice of thinner with different properties will affect the drying time of the paint, reflectivity, color effect and flow, while both linseed oil and olive oil give the best flow and gloss when the paint is mixed.

To sum up, the color pigment prepared by the present invention can reflect more excellent color quality, brighter and brighter color, stronger color saturation and tinting strength, and MgCO ₃ , Na ₂ CO ₃ and CaCO ₃ are introduced into the formula of the present invention. One or more carbonates such as , BaCO ₃ , etc., accelerate the escape of bubbles in the process of pigment preparation, and play a gradient clarification effect on the pigment, so that the pigment can improve the performance of the pigment, and at the same time it will not increase economic costs. In addition, the use of linseed oil or olive oil as a diluent makes the pigments have the best fluidity and gloss after mixing, and the produced pigments do not contain formaldehyde, which is more environmentally friendly and convenient for painting. In addition, by using the preparation method of the lacquer painting of the present invention, the lacquer painting handicrafts can be produced in an industrialized manner by utilizing modern industrial technology.
