Color masterbatch antioxidant
The color masterbatch is a high concentration of colored granule made from colorant, carrier resin, dispersant, coupling agent, surfactant and synergist. Using color masterbatch to produce colored plastic products is a widely used method in the production of plastic products. Generally speaking, the carrier resin used in the production of color masterbatch is lower than that of the basic resin used in the production, and the melting index is high.
Carrier resin in color masterbatch production passes through heat for the first time, in the process of plastic products production again after hot extrusion, carrier resin first thermal degradation and mechanical degradation, thus accelerating colored plastic products of the aging process. Although the carrier resin in the color masterbatch is not a large proportion in the colored plastic products, the heat oxidation has occurred in the secondary or secondary heat. Therefore, the production of color masterbatch and the use of color masterbatch to produce colored plastic products must be added to the color masterbatch antioxidant.
Anti - thermal oxygen aging function is the basic function of anti - aging of general plastic material, and the function of anti - light aging is based on the basic function. To enhance the light stability of colored plastic products, first of all, the thermal and oxygen stability of colored plastic products should be enhanced. In some plastic products with ultraviolet absorption pigment, appropriate and appropriate color masterbatch antioxidant can be used to double the light stability of the products. According to the data, in high pressure polyethylene, it is not possible to improve the light stability of polyethylene by using chrome yellow, iron oxide red or color parent antioxidant 2246. The stable performance of high - pressure polyethylene was more than three times higher when chrome yellow or iron oxide red with antioxidant 2246. The essential role of antioxidant 2246 in this experiment is to enhance the thermal and oxygen stability performance of high pressure polyethylene. Objective performance or result is to enhance the light stability of high pressure polyethylene.
When light is applied to the colored plastic products, part of the light reflects from the surface, causing a sensation of gloss; The other part of the light is refracted and transmitted into the plastic, and the light meets the pigment granules and will cause reflection, refraction and transmission. Colored plastic contains yellow and blue pigments. With optical analysis, incident light can produce three phenomena.
When light is injected into the yellow pigment, the reflected light is the complementary color of blue that is absorbed by the yellow pigment -- yellow. When the light hits the blue pigment, the same is true for blue light. Successively by yellow, and blue pigments, light first absorbed the violet light and blue light, and blue - green,, yellow, green, yellow, orange and red light through, and then through the blue paint, are yellow, orange, red, colorful light is absorbed. Finally, only blue-green, green, and yellow-green light are reflected off (in contrast, through blue and yellow pigments).
Triphenyl phosphite (antioxidant, stabilizer TPPi)
Packing method: net weight of 200KG/galvanized iron bucket (a small cabinet to hold 16 tons), 1000KG/IB (a small container with 18 tons) or 23 tons of it.
Port of shipment: Shanghai port
Price quotation validity: 15 days
Warehouse time: within 15 days (customs clearance)
Export rights: our own right to import and export.
Triphenyl phosphite (TPPi antioxidants, stabilizer) is mainly used in PVC, polyethylene, polypropylene, polystyrene, polyester, abs resin, epoxy resin, synthetic rubber antioxidant stabilizer, used in polyvinyl chloride (PVC) products as a chelating agent.
The mixing of color and color is mixed, usually only mixed with red, yellow and blue. The so-called red color can be seen through red wavelengths (so people can feel red), absorbing green and nearby color wavelengths. The same goes for yellow and blue. When the yellow and blue are mixed, the bands of the yellow pigment absorption band, the blue pigment absorbs the long band, only the middle green band is left, and the people feel green. Similarly, when the red and yellow are mixed, the longer wavelengths above 560nm pass through and become orange. In the same way, red and blue together become purple.
People often call red, yellow and blue the three primary colors. There are three kinds of intercolour. Red and blue to purple; Yellow and blue become green; Red and yellow are orange. The color of the two colors is called "complex color", such as olive, brown, blue ash, etc.
Most colorants, especially inorganic pigments, can play a certain role in light stabilization when used alone in plastic products. For long - term outdoor use of colored plastic products, can not only rely on colorants to improve the light stability of products. Only by using the light stabilizer can the light aging speed of colored plastic products be suppressed or slowed down effectively, and the light stability of colored plastic products can be significantly improved.
Hindered amine light stabilizer (HALS) is a kind of organic amine compound with space steric effect, and because of its decomposition of hydrogen peroxide, quenching state oxygen free radicals, capture, and effective groups can recycling function, is the light ageing efficiency is high, the dosage of the biggest plastic light stabilizer at home and abroad. Table 19 data show that suitable photostabilizer or appropriate antioxidant and light stabilizer combination system can be used to increase the light and oxygen stable performance of colored plastic products.
For light activity and photosensitivity stain (such as cadmium yellow, not package nuclear rutile) colored plastic products, considering the catalytic light aging effects of the colorant, light stabilizer adding quantity will increase.
