Problems solved by technology

[0003] However, painting or electroplating will bring three problems: first, this type of surface treatment process is very harmful to the environment or operators; It is difficult to recycle parts and cannot be recycled and reused, resulting in waste of resources; thirdly, due to the complexity of the painting process, basic links such as pretreatment, painting and transportation need to be added. Such a complicated procedure may cause yield problems, which will greatly increase the processing cost of plastic parts
[0004] The traditional spraying technology of nylon parts has gradually been unable to meet the needs of the new era, and technological breakthroughs are urgently needed

Embodiment 1

[0032] Put 6650 parts of nylon, 5 parts of maleic anhydride grafted polyolefin elastomer, 10980.6 parts of antioxidant, 1680.4 parts of antioxidant, 2 parts of silicone, and 1 part of aluminum powder masterbatch into a high-speed mixer, and mix for 6 minutes. Then, the above-mentioned component mixture is continuously fed into the twin-screw extruder from the hopper, and 40 parts of glass fibers are fed into the barrel of the twin-screw extruder from the feeding port in the middle of the extruder in a side-feeding manner for mixing. Cool, dry, and pelletize to obtain a reinforced nylon composite material with metallic luster. The temperature range of each section of twin-screw extruder barrel from feeding port to machine head is: Zone I: 230°C, Zone II: 250°C, Zone III: 250°C, Zone IV: 250°C, Zone V: 250°C, Zone VI Zone: 250°C, Zone VII: 250°C, Zone VIII: 240°C, Zone IX 240°C, screw speed 600r / min; 99 parts of the obtained carbon fiber reinforced nylon composite material and 1...

Embodiment 2

[0034] Put 6668.5 parts of nylon, 1 part of maleic anhydride grafted polyethylene, 10980.12 parts of antioxidant, 1680.08 parts of antioxidant, 0.3 part of polytetrafluoroethylene, and 5 parts of zinc powder masterbatch into a high-speed mixer, and mix for 3 minutes. Then, the above-mentioned component mixture is continuously fed into the twin-screw extruder from the hopper, and 20 parts of glass fibers are fed into the barrel of the twin-screw extruder from the feeding port in the middle of the extruder in a side-feeding manner for mixing. Cool, dry, and pelletize to obtain a reinforced nylon composite material with metallic luster. The temperature range of each section of the twin-screw extruder barrel from the feed port to the head is: Zone I: 235°C, Zone II: 255°C, Zone III: 255°C, Zone IV: 260°C, Zone V: 260°C, Zone VI Zone: 260°C, Zone VII: 255°C, Zone VIII: 245°C, Zone IX 245°C, screw speed 600r / min; put 95 parts of the obtained glass fiber reinforced nylon composite ma...

Embodiment 3

[0036] Put 6670 parts of nylon, 3 parts of maleic anhydride grafted polyolefin elastomer, 10980.6 parts of antioxidant, 1680.4 parts of antioxidant, 1 part of calcium stearate, and 3 parts of copper zinc powder masterbatch into a high-speed mixer, mix 4 minutes, then, the above-mentioned component mixture was continuously added into the twin-screw extruder from the hopper, and 20 parts of carbon fibers were added into the barrel of the twin-screw extruder through the feeding port in the middle of the extruder in a side-feeding manner for mixing. strips, cooled, dried, and pelletized to obtain a reinforced nylon composite material with a spraying effect. The temperature range of each section of the twin-screw extruder barrel from the feed port to the head is: Zone I: 240°C, Zone II: 270°C, Zone III: 265°C, Zone IV: 270°C, Zone V: 270°C, VI Zone: 270°C, Zone VII: 270°C, Zone VIII: 260°C, Zone IX: 260°C, screw speed 600r / min; put 98 parts of the obtained carbon fiber reinforced n...

Abstract

The invention relates to a nylon material and a preparation method thereof, in particular to a light free-spraying nylon material and a preparation method thereof and belongs to the technical field of high polymer materials. The light free-spraying nylon material is prepared from, by weight, 50-70 parts of nylon, 20-40 parts of a reinforcing agent, 1-5 parts of compatilizer, 1-5 parts of foaming agent masterbatch, 1-5 parts of metallic pigment masterbatch, 0.3-2 parts of a lubricating agent and 0.2-1 part of an anti-oxidization agent. Due to the fact that the metallic pigment masterbatch of different colors is added in the reinforced nylon, the modified nylon material has metallic luster, tedious operation of traditional paint spraying, electroplating and the like is omitted, procedures are greatly simplified, and the nylon material is more environmentally friendly; meanwhile, the micro foaming technology is adopted, and therefore the weight of a manufactured piece can be remarkably reduced, the maximum weight reducing range is 20% or above, the equipment requirement is low, the product yield is high, and benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a nylon material and a preparation method thereof, in particular to a light-weight spray-free nylon material and a preparation method thereof. Background technique [0002] Nylon is an important engineering plastic, which is widely used in machinery, automobiles, instruments and other industries, especially when it is used in some decorative stress-bearing parts, while requiring nylon to maintain high rigidity, it has good appearance and decoration requirements Many manufacturers will plate a layer of metal or spray paint on the surface of the product, so that the product has a bright appearance and improve the texture of the product. [0003] However, painting or electroplating will bring three problems: first, this type of surface treatment process is very harmful to the environment or operators; It is difficult to recycle parts and cannot be recycled and reused, resul...
