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...

Examples

preparation example Construction

[0036] The present invention provides a method for preparing a paint-free material with metallic luster described in the above technical solution, comprising the following steps:

[0037] Mix micron-sized metal powder, plasticizer, toughener, lubricant and plastic in a high-speed mixer to obtain a mixture, granulate, and dry to obtain blended masterbatch pellets;

[0038] The blended masterbatch pellets are mixed with an antibacterial agent and an organic pigment to obtain a paint-free material with metallic luster.

[0039] see figure 1 , figure 1 The specific process flow chart that has metallic luster free paint-free material that the present invention provides, by figure 1 It can be seen that:

[0040]The metal is crushed and sieved to obtain micron-sized metal powder; the micron-sized metal powder, plastic, and additives are mixed at high speed to obtain a compound; the compound is twin-screw extruded and pelletized to obtain a masterbatch; the masterbatch, colorant an...
