Metal-luster paint-spraying -free material and preparation method thereof as well as paint-spraying -free wire

Abstract

The invention provides a metal-luster paint-spraying -free material and a preparation method thereof as well as a paint-spraying -free wire, the metal-luster paint-spraying -free material comprises the following components in parts by mass: 2-6% of micron-scale metal powder, 86-92% of plastic, 1-5% of a flexibilizer, 1-4% of a plasticizer, 1-3% of a lubricant, 0.5-3% of an antibacterial agent and0.01-0.6% of an organic pigment; the micron-scale metal powder is selected from one or more of micron-scale copper-zinc alloy powder, micron-scale pure copper powder and micron-scale pure zinc powder.The micron-scale metal powder is adopted, the compatibility of the micron-scale metal powder and the plastic and the additive is good, so that the metal-luster paint-spraying -free material has goodprocessability, can be fused or emulsified after being heated, and can be precipitated into a floating sheet shape after being cooled, so that strong metal luster is generated. The metal-luster paint-spraying -free material is smooth in surface and relatively good in glossiness, and the glossiness can reach 40-50; and the metal-luster paint-spraying -free material also has relatively good mechanical property and antibacterial property; the antibacterial rate (staphylococcus aureus) is greater than or equal to 92%.

Description

technical field [0001] The invention belongs to the technical field of paint-free materials, and in particular relates to a paint-free material with metallic luster, a preparation method thereof and a paint-free wire. Background technique [0002] The paint-free material is to add metal powder, pearl powder, ceramic powder, high-gloss toner, etc. with different display effects into the plastic raw material by melt blending, so that it has its own special color effect. Paint-free materials have the advantages of high gloss or matte gloss, green environmental protection (avoiding environmental pollution by spraying), cost saving (simple process, high yield rate), etc. Compared with spray-painted plastics, although spray-free plastics are 10% more expensive than ordinary plastics, the cost of using spray-free plastics has dropped by 20% to 30%, including the cost of painting. [0003] In the prior art, the plastic material has high gloss usually by adding inorganic pearlescent...

Problems solved by technology

[0004] However, the use of inorganic pearl mica powder will greatly reduce the processing performance of the material, and the melt fluidity of the material will be low

Moreover, the compatibility of inorganic pearlescent mica powder with most organic polymeric matrices is often poor, and other means (chemical modification, adding compatibilizers, etc.) are often required to improve the compatibility between the inorganic phase and the organic phase during processing and preparation.
