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...

Embodiment 1

[0051] (1) Micron-sized metal powder (being copper-zinc alloy powder, wherein copper accounts for 97%, zinc accounts for 3%), plasticizer (polyethylene glycol), lubricant (zinc stearate), toughening agent ( Nano-silica) and ABS are taken out after mixing 5min in a high-speed mixer in proportion to obtain a mixture; wherein, copper-zinc alloy powder 5%, polyethylene glycol 2%, zinc stearate 1%, nanometer dioxide Silicon 2%, ABS 90%.

[0052] (2) Melt-extrude the obtained blend through a twin-screw extruder and pelletize it. The temperatures of the 1-6 sections of the extruder are respectively 175°C, 175°C, 180°C, 185°C, 190°C and 190°C to obtain Masterbatch pellets are fully dried at 80°C for 24 hours.

[0053] (3) Mix the obtained masterbatch with organic pigment and antibacterial agent (enrofloxacin hydrochloride) in a high-speed mixer in a certain proportion for 5 minutes and then take it out. The ratio is: 98.5% of masterbatch, 0.5% of organic pigment, enrofloxacin hydroch...

Embodiment 2

[0057] Micron-sized metal powder (copper-zinc alloy powder, in which copper accounts for 95% and zinc accounts for 5%), plasticizer (palm oil), lubricant (polyethylene wax), toughening agent (nanocellulose) and PP Take it out after mixing in a high-speed mixer for 5 minutes to obtain a mixture; wherein, 5.5% of copper-zinc alloy powder, 2.5% of palm oil, 2% of polyethylene wax, 1% of nanocellulose, and 89% of PP.

[0058] (2) Melt-extrude the obtained blend through a twin-screw extruder and pelletize it. The temperatures of the 1-6 sections of the extruder are respectively 170°C, 170°C, 175°C, 180°C, 180°C and 180°C to obtain Masterbatch pellets should be fully dried at 80°C for 12-24 hours.

[0059] (3) The obtained masterbatch pellets are mixed with organic pigments and antibacterial agents (nano-titanium dioxide and nano-silver are blended at a mass ratio of 1:1) in a high-speed mixer in proportion to take out after mixing for 5 minutes, wherein the masterbatch accounts for...

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...
