Color masterbatch is an important formula of plastic coloring, endowed with plastic colorful flowery style, make originally drab plastic color colorful charming angel, and quickly swept every corner of the world, and in the streets, in the trend of the urban noise, become a legend of plastics coloring.

For this reason, many people wonder how the color mother and the plastic blend together and write the colorful chapters. For everyone's confusion, the small make up column tells the plastic issue of color matching, spare no effort to deduce the color "magic" of color mother material.

Identify the color palette target

1. Have a clear and comprehensive understanding of the required samples. Because, sample can be obtained, not be the only, generally can be plastic parts, the pantone number, photos, leather, metal parts, etc., all colors, all may be you need to know.

2. According to the plastic material, the soft and hard glue powder is distinguished. This will narrow the range of the color powder.

3. Choose the color or color mother according to the molding process (e.g. medium temperature or heat resistance).

4. There are special requirements for weather resistance, chemical resistance, fillings or other additives and environmental protection.

5. Under what light source to color, whether have requirement. Because of the sample, in natural light, fluorescent lamp, ultraviolet ray and so on different light source, the color will have different.

The second

Analysis of hue

Adopt the color scheme of the next color, make the main color with blue, use green green as the ornament color. The visual point is from left to right. Picture style overall calm, stable and soft.

The steps to analyze the color phase:

1. Observe the transparency of the sample

Generally divided into transparent, translucent, and opaque three (also known as the solid color, solid color refers to the very low transparency), there are two kinds of adjustment method of transparency, one is increasing titanium pigment, 2 it is to increase the saturation toner.

2. Observe the surface of the sample

(1) if the surface of the sample is anti-white, which is the solid color with some white light, that indicates that the sample contains titanium white powder. If the anti-white is heavy, the content of titanium dioxide is sure to be abundant.

(2) if the sample is very bright, it is the color degree, the amount of titanium white powder and the amount of colored powder will be used. (color powder, bright color, dark color; Instead, it's light and bright.

(3) if the surface of the sample is bright and bright, and the surface is anti-white, it can only increase the amount of titanium white powder and increase the dosage of color powder.

Note: if the sample is transparent, choose an organic pigment or dye that is transparent. If it is opaque or semi-transparent, it is necessary to estimate the amount of titanium dioxide in the sample according to the actual experience, and then determine whether to add the black proportion according to the color phase.

How do I determine the color palette

1. Determine the content of titanium dioxide in the first place, which is the key to the technology. Because of the change in the content of titanium dioxide, the color will change greatly, and the amount of other color powder will change accordingly.

2. Analyze the color range of the color sample to be composed of which color, which is the main color, which is the vice color, and the proportion of each. (try to choose pigments that are similar to the color of the sample, such as the color of the red color, the color of the sample is red, and the color is red or fluorescent red.

3. Observe the freshness of the sample and consider whether to add the fluorescent powder or add the whitening agent.

four

Try to match

1. According to the previous analysis, select the appropriate color powder and construct the formulation;

2. Choose soft glue or hard glue according to the category of raw materials.

3. Select the pigment according to the transparency, determine the content of titanium dioxide and the degree of black and grey, and finally determine the hue, depth and brightness to choose the color powder variety.

five

Draw up the color

1. Determine the ratio of titanium white powder

2. Determine the proportion of black color powder

3. Determine the proportion of main colors

4. Determine the proportion of colorizing powder (the proportion of fluorescent powder or whitening agent)

Injection molding fine tuning

In general, it is used for blending with 600g resin. According to the proportion of formula, the color powder and resin are mixed, and then the injection molding machine is used to make the plate. After playing board, for sample cooling completely, and the color of the sample were analyzed, according to the sample of the color of the bright hue, depth, extent and subtract dosage of toner, trial and error until the expected color matching requirement. (for example, using computer test color scheme, data analysis can be performed according to the deviation of L, a and b.)

seven

Take white as an example to illustrate the point of attention

1. In general, the finer the particles of titanium dioxide, the higher the coloring force. Commonly used titanium white dupont R105;

2. White is commonly used in light-colored plastic products, usually with a large amount of titanium white powder and a small amount of pigment to configure;

3. Choose the titanium white powder with blue light on the base color;

4. The higher the content of titanium white powder in PC/ABS, the better the hiding power, but the covering power will not rise when greater than 8%.
