How to mix silicone products? How silicone is colored

For the color matching and color matching work of silicone products, the operator has rich operating experience and good color discrimination ability, and it is necessary to understand and be familiar with the flexible use of various color masterbatches, and the whole color matching process must be in line with the slow transformation from light color to dark color, and each time the color matching color needs to record the corresponding data, you must know that sometimes the data is the most accurate, record the masterbatch component, until the actual color and target.

When the colors are similar, it is also necessary to summarize the color formula of the color matching color and record it, so as to accumulate effective data for the next time and shorten the time of color matching.

Well-known factory of silicone products: Kotelly! It can be done according to the requirements of the drawing ingot!

First of all, to understand that the color matching and color matching of silicone products are two different concepts, color matching is that we first have a target color, and then according to our experience to match the masterbatch, the various masterbatches are matched in proportion, and then the color matching is the product closest to the target color, and the color matching is to adjust the existing color to the product closest to the target color. The operation of color mixing between the two is mandatory.

To do lag based on color matching, and different color matching is necessary to draw up the formula from scratch and wake up to change the color, for the color and color matching of silicone products are to be based on the operator has rich experience in operation and good color.

The ability to distinguish depends on the ability to understand and be familiar with the flexible use of various masterbatches, and the whole color matching process must be in line with the slow transition from light color to dark color, and each time the color matching color needs to be recorded accordingly.

data, to know that sometimes the data is the most accurate, record the masterbatch component, until the actual color and the target color are close to the color also need to summarize the color formula of the color matching color and record it, so as to facilitate the next product.

Accumulate valid data and shorten the time to match colors.

Methods and methods: 1. Add color paste to the liquid glue; When making silica gel products with liquid silica gel, add color paste to the liquid glue and stir evenly, the silica gel made by this method has strong color fastness and is not easy to fade. The disadvantage is that a bucket of liquid glue can only adjust one color, which is not suitable when the same product needs multiple colors.

2. The surface of the silicone product is brushed; Some Fuzhifile products need to be brushed with a variety of colors after molding, and professional silicone ink can be used to color, and the brushing method can be used. The disadvantage is that this method has high quality requirements for silicone ink, and silicone ink needs to be heated to maintain the color for a longer time.

3. Transfer printing or pad printing, this method is to use the pad printing glue head and other transfer pattern tools, dip the ink on the rubber head and then transfer to the silicone.

1. Solution coloring: This method is to dissolve the rubber into a solution of a certain concentration with its good solvent, and then remove the colorant and sulfur.

The external rubber compounding agent is added to the solution, stirred and mixed evenly, dried at a certain temperature to remove the solvent, and finally added sulfur to the rubber mixer. This coloring method is complex to manipulate and scatter, and the colorant and compounding agent are unevenly dispersed, with color difference, solvent difficulty, and environmental pollution, so it is rarely used at present.

2. Mixing method coloring: this method is the most commonly used method for coloring silica gel products, which is to directly add the colorant or mix it with the carrier and then add it to the rubber compound, and mix it evenly through the rubber mixer to color the rubber.

1. Solution coloring: This method is to dissolve the rubber into a solution of a certain concentration with its good solvent, and then add the colorant and the rubber compound except sulfur to the solution and stir and mix evenly, dry and remove the solvent at a certain temperature, and finally add sulfur to the rubber mixer. This coloring method is complex to operate, the colorant and the compounding agent are unevenly dispersed, there is color difference, the solvent is difficult, and the environment is polluted, so it is rarely used at present.

Silicone can be colored with silicone masterbatches. Silicone masterbatch is used for coloring various silicone products and is suitable for the molding process. It is an indispensable raw material for the coloring of silicone products. Silicone masterbatch material components: siliconogenic gum, toner, silicone oil, dispersant.

According to the main properties, it is divided into organic masterbatch, organic fluorescent masterbatch and inorganic masterbatch. It is a solid masterbatch and a colorant.

1. Characteristics of organic masterbatch: complete color system, bright color, good transparency, high tinting strength.

2. Organic fluorescent masterbatch: the color is very bright and can emit light under UV ultraviolet irradiation, but its weather resistance and heat resistance are poor, and the tinting strength is low.

3. Inorganic masterbatch: high temperature resistance, good dispersion, excellent weather resistance, strong hiding power, but low tinting strength.

Just add silicone masterbatch to mix the color, and the finished silicone product can be colored by spraying ink.

1.Selection of containers: drying ovens or metal cans with a larger diameter.

Drying ovens can be purchased online or at camera stores** The order is relatively high. Metal cans can be found at home with metal cans with a larger diameter, such as iron milk powder cans, coffee cans, etc., cleaned and dried for later use.

2.Color-changing silica gel: It is best to choose a silica gel with a larger particle size and smoothness, as few broken particles as possible, and the bluer the color, the better. To use, sprinkle the eggplant evenly on the bottom of the drying oven or jar.

3.Put in the camera: After the lens cap is covered, wrap it in a soft silk cloth, and then put it into a food fresh-keeping bag and tie it tightly, and put it in two sealed cans respectively to wrap it directly, pay attention!

Do not allow the digital device to come into direct contact with the discolored silicone. Finally, close the lid and press the lid evenly to close it.

4.Regularly check and restore the dryness of color-changing silica gel: due to humidity, the silica gel will change color after moisture absorption, from dark blue to light blue or the jujube is pink to white.

When you see a change in the color of the silica gel, you can take out the silica gel, put it in a porcelain dish, put it in the microwave oven and heat it with a micro-trembling silver wave, until the silica gel returns to dark blue, take it out and let it cool, and then put it in a container for recycling, and so on.
