Ask the furniture painter about color matching.

1, pay attention to the paint color matching principle.

Generally, do not use more than three kinds of paints for color matching. On the basis of primary colors, adding white can get colors with different saturation (that is, colors with different shades). On the basis of primary colors, red, yellow and blue are mixed in a certain proportion to get different intermediate colors (i.e. colors with different tones), and then colors with different brightness (i.e. colors with different brightness) can be obtained.

There are two bases for mixing colors:

One is the color prepared according to written or oral requirements, which is more convenient and easy for oil workers. However, the choice of color is very important. If the color selection is not appropriate, the effect of color matching is not ideal. For example, when blending medium green, any yellow and blue can be blended into medium green, but only the purity of yellow and blue is better, and medium green is purer and brighter.

The other is to allocate according to the requirements of the model, which is demanding and technical, which is not easy for ordinary oil workers to do. Mainly rely on practical experience, and compared with color cards, identify which kinds of monochrome are composed of excellent color cards, and what is the approximate proportion of each monochrome, and then try to match with the same variety of paint. After being approved by the design and construction unit, the painting method is the same as or similar to the sample, and the color is the same as the sample.

2, coating consistency deployment due to storage or climate reasons, resulting in coating consistency is too large, should be mixed with the right amount of diluent in the coating, make its consistency decline, in order to meet the construction requirements. The amount of diluent should not exceed 20% of the coating weight, which will reduce the performance of the film. Diluent must be used together with paint and cannot be abused to avoid quality accidents. For example, shellac paint should use ethanol and nitrocellulose paint should use banana oil.

3. Colorant blending is mainly used to blend the colors of water, wine and oil on the wood surface.

When it comes to furniture paint color matching, we must first understand some color-related knowledge, and the principle of three primary colors is universal. As we all know, the competition in the furniture industry is becoming more and more fierce. Merchants not only ensure the novelty of quality and style, but also ensure the diversity of furniture colors. Only in this way can we be more competitive.

First, the method of furniture paint color matching

We talked about color earlier, now let's talk about the preparation and precautions of color paint; Color-blind people can't adjust the color of paint in natural light. The color matching of paint should be based on the color of the sample. First, try to match the sample. After checking the sample, make sure that there are several kinds of multicolor paints in the sample. Then, put these pigments in a jar, weigh them first, and then use them to color. After the color matching is completed, weigh it once. The difference of the third weighing is the weight of all kinds of paints involved in color matching, which is used as a reference when mixing samples.

Due to storage or climatic reasons, the consistency of the coating is too large, so an appropriate amount of diluent should be added to the coating to reduce its consistency to meet the construction requirements. The amount of diluent should not exceed 20% of the coating weight, which will reduce the performance of the film. Diluent must be used together with paint and cannot be abused to avoid quality accidents. For example, shellac paint should use ethanol and nitrocellulose paint should use banana oil.

Attention should be paid to the color matching of furniture paint:

1. When preparing colorful coatings, choose coatings with the same performance to match.

2. When matching colors, we must first choose the main color and estimate the proportion of various colors. Then the color should go from shallow to deep, and the country should stir.

3. Pay attention to what auxiliary materials should be added in the preparation process, and add accelerators and diluents. Curing agent and so on.

4. When gray and green paints are mixed, they are made of medium colors and may appear (floating colors). At this time, a little silicone oil can be added to prevent it, {1: 1000} 5. Color mixing in the sun, the color after color mixing should generally be slightly lighter than the original sample.

Second, the color matching skills of furniture paint

1, color matching needs to be cautious. Generally, samples are taken first, and the amount of color matching paint is preliminarily obtained, and then details are prepared according to the results of the samples. First, adjust the secondary color and secondary color in a small container.

2. First add the main color (the color with large dosage and low tinting power), then slowly and intermittently add the dark color (or tinting) with high tinting power, constantly stir and observe the color change at any time.

3, "from shallow to deep", especially when adding pigments with strong coloring power, don't overdo it.

4. When matching colors, the colors of paint and dry film will be slightly different. The colors of various paints are generally light when wet, and dark when dry. Therefore, if the sample is a dry sample, the color matching paint needs to be dried before it can be compared. If the sample is wet, you can drop a drop of the sample in the color-matching paint to see if the two colors are the same.

5. It is necessary to know in advance the floating degree of primary colors and the changes of coating materials in colorful coatings, especially amino coatings and perchloroethylene coatings.

6. When preparing colorful coatings, the coatings with the same quality should be mixed with each other, and the solvent system should also be mutually soluble. Otherwise, due to the poor miscibility of the coating, the quality will be affected, and even delamination, precipitation or gelation will occur, making it unusable.

7. Because colors often have different color heads, if they are paired with positive green, they are generally yellow with green heads and blue with yellow heads; When purple and red are matched, blue with red head and red with blue head should be adopted; When matching orange, use red with yellow head and yellow with red head.

8. Pay attention to the color of auxiliary materials such as drier, curing agent and diluent, so as not to affect the color.

9. When preparing multi-color paints such as gray and green, it is easy to appear "floating color" and "halo color" because of the different densities and oil absorption of various pigments. At this time, a small amount of surfactant, leveling agent and anti-floating agent can be added as appropriate to solve the problem. Add 0. 1% silicone oil as usual for prevention. Various surfactants produced by foreign companies need to distinguish which solvent system to use, and the addition amount is generally 0. 1% ~ 1%. (10) Using the slightly transparent characteristics of the paint film and choosing a suitable background color, the color of the top coat can be more vivid than the original paint. This is a color produced by the superposition of background color and primary color according to the principle of natural light reflection and absorption, which is called "transparent color" in coating engineering. For example, yellow primer can make red more vivid, gray primer can make red more vivid, positive blue primer can make black more vivid, and water blue primer can make white more clean and innocent.
