Many consumers are attracted by the color and appearance of some products, especially in gifts and handicrafts. As we all know, silicone products are a kind of rubber and plastic products that are inherently practical and beautiful, and are used in daily life. In addition to its functional role, the reason why it can achieve multi-color effects and saturated color systems is mainly because a lot of time has been invested in the appearance and color of the adjustment, so what are the methods for the detailed process What?
First of all, we must know that the color pigment material of the color master batch is a silica gel material for coloring. Various color additives are added to the silica gel material to achieve a certain color system effect. Its chemical additives are mainly formulated for the raw materials of silicone products and cannot be used. Among other materials, the color matching can be used in any products without any influence, such as daily silicone products, silicone decorative products, silicone gifts, and some electronic peripheral accessories.
What are the basic characteristics of silicone color master batch?
1. Light resistance of silicone color master batch
The light resistance of silicone color master batch refers to the light resistance of the color master batch. Disperse the pigment in a certain medium to prepare a sample. At the same time as the "Light Fastness Blue Standard" sample card, under the specified light source, after a certain period of exposure, compare the degree of discoloration, and indicate that 1 Grade 8 is the worst and Grade 8 is the best.
2. Heat resistance of silicone master batch
The heat resistance of silicone master batch refers to the heat resistance of the master batch. The higher the number, the better the heat resistance. The pigment is dispersed in polyolefin to make one-third of the standard color, and it stays for 5 minutes after molding in the injection molding machine.
3. Migration resistance of silica gel master batch
The migration resistance of silica gel master batch refers to the ability of the color master batch to resist migration. Migration refers to the migration of the colorant from the inside of the product to the surface of the product or from a product through the interface to the product and solvent.
In the production and processing of silica gel master batch, the pigment is under the action of additives, and the silica gel master batch is thoroughly mixed with the carrier through sufficient mixing. When in use, put a certain amount in the silica gel to be processed, and the color master batch quickly enters the character, and the silica gel is recognized as "in-law". Affinity-Compatibility is significantly better than toner coloring. Therefore, it is better for manufacturers of film and silicone products.
What should be considered when purchasing silicone color master batch? From the perspective of manufacturers of silicone products-in order to produce general-purpose silicone color master batches, it is necessary to select pigments with a higher heat resistance grade and a wide range of applications. After the temperature resistance of the pigment powder reaches a certain level, it will increase by 10℃～20. ℃, the cost of the pigment will rise by 50% to 100%.
