Detailed Description
The invention provides a degradable high-brightness white silver spraying-free material and a preparation method thereof, and the invention is further described in detail below in order to make the purpose, technical scheme and effect of the invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The spraying-free material is a novel environment-friendly material which can realize various pearlescent, colorful or metal appearance effects by adding special pearlescent powder or metal pigment and the like into specific resin and modifying the special compatible technology to directly perform injection molding. The existing spraying-free material system is divided into a three-dimensional flashing highlight non-flow mark series and a metallic pearly-luster effect series, the existing spraying-free material mainly comprises spraying-free composite PP, spraying-free PC, spraying-free ABS, spraying-free PC/ABS alloy and the like, the main application fields of the spraying-free material system comprise daily household appliances, intelligent homes, automobile interior/exterior trimming parts, 3C high-end consumer electronics, artificial intelligent machines, beauty instruments, cosmetic packages and the like, and the spraying-free material system can also conform to the market demands and development trends to send different product effects.
Compared with the traditional spraying material, the spraying-free material has the advantages of good one-step forming, no need of spraying to obtain gorgeous appearance, greenness, environmental protection, lower cost and higher design freedom.
However, the research of the current spray-free materials mainly focuses on adding single metal powder or pigment to realize a certain color effect, and the research on the combination of metal powder, pearl powder, pigment and the like to realize high metal texture is less; and at present, almost no research on the high-brightness white silver spraying-free material with the degradation function exists in the market.
Based on the above, the embodiment of the invention provides a degradable high-brightness white silver spray-free material, which is characterized by comprising, by weight, 100 parts of ABS resin, 0.5-5 parts of metal aluminum powder, 0.1-2 parts of pigment, 0.5-5 parts of pearl powder, 0.5-5 parts of dispersing agent, 1-10 parts of degradation assistant, 0.1-1 part of antioxidant and 0.1-1 part of stabilizer.
In this embodiment, the ABS resin is a graft copolymer of three monomers, namely Acrylonitrile (Acrylonitrile), 1, 3-Butadiene (Butadiene), and Styrene (Styrene), and the ABS resin is one of the most widely used polymers with the largest yield, organically integrates various properties of PS, SAN, and BS, and has excellent mechanical properties of toughness, hardness, and rigidity; the metal aluminum powder is used as metal addition powder of a spraying-free material, and can show the effect of metallic silver texture after being added; the pigment can be added to achieve the effects of increasing tinting strength and color saturation; the pearl powder can improve the decorative effect of the spraying-free material and more highlight the brightness of metallic silver.
Specifically, the metal aluminum powder mainly plays a silver effect, if the weight ratio of the metal aluminum powder is less than 0.5 part, the covering effect of the metal aluminum powder on plastics is poor, the silver color is not prominent, and if the weight ratio of the metal aluminum powder exceeds 5 parts, the dispersion of the metal aluminum powder is poor, so that the performance of the final spraying-free material is obviously reduced. The pearl powder is a lustrous pigment and is formed by coating mica with a plurality of metal oxide thin layers, and different pearl effects can be generated by changing the metal oxide thin layers; because the pearl powder has the characteristics of soft pearl luster like silk, starry flashing effect, effect of color variation along with angles and the like, the addition of the pearl powder in the embodiment mainly plays a role in highlighting the silver color, so that the silver color is more highlighted, if the addition proportion is lower than 0.5 part, the highlighting effect on the silver color is not obvious, and if the addition proportion is higher than 5 parts, the performance of the spraying-free material is influenced. The addition of the pigment mainly highlights whiteness, and the obtained spraying-free material is closer to the effect of paint spraying or electroplating.
In the embodiment, the material with high metal texture and high bright silver color effect is prepared by compounding three components of metal aluminum powder, pearl powder and pigment, and the brightness of the material can reach 31 by a test of a hexagon instrument; in addition, the high-brightness white silver spraying-free material has the capability of degrading under anaerobic conditions by adding the degradation auxiliary agent, and is beneficial to environmental protection.
In some embodiments, the pearlescent powder has a flake structure, and compared with pearlescent powder with a cubic and spherical structure, the pearlescent powder with the same volume fraction has a more obvious covering effect and a prominent highlight effect.
In some embodiments, the pigment is one or more of a monoazo pigment, a disazo pigment, a lake pigment, a phthalocyanine pigment, and a premium ring pigment, but is not limited thereto.
In some embodiments, the prodegradant is an Ecoplastic Technology Limited degranulation masterbatch. The Ecoplastic Technology Limited degradation master batch is an environment-friendly biodegradable plastic master batch, and the degradation master batch is added into the spraying-free material, so that the spraying-free material has better degradation capability under anaerobic conditions, and the environment pollution is avoided. The degradable high-brightness white silver spraying-free material is characterized in that the dispersing agent is PE wax or stearic acid amide.
In some embodiments, the antioxidant is one or more of a hindered phenolic antioxidant and a phosphite antioxidant, but is not limited thereto.
