Negative ion plastic and preparation method thereof

Abstract

The invention discloses a negative ion plastic and a preparation method thereof, wherein the negative ion plastic is prepared from raw material resin, a coupling agent, a composite negative ion material, an antioxidant, a weather resistant agent and a lubricant; by mechanical dispersion, granulation processing and extrusion molding of various household electrical appliance commonly used parts, such as internal and external plastic parts on an air conditioner, refrigerator internal plastic parts, all kinds of automotive internal plastic parts and the like, the surface of the parts can continuously emit negative ions to air; the negative ion plastic comprises the raw materials by ratio: 83-88 parts of a plastic raw material, 4-8 parts of the composite negative ion material, 6-10 parts of the coupling agent, 0.2-0.6 part of the antioxidant, 0.2-0.6 part of the weather resistant agent and 0.5-1.0 part of the lubricant. The negative ion plastic is prone to large-scale industrial production, and the product has extremely high cost-effective ratio; the coupling agent with better use effect is used, and bad appearance, poor performance and other non-ideal results of plastic parts caused by agglomeration and other badness of a negative ion powder in a matrix are solved; the negative ion plastic makes the surface of decorative materials release negative ions, and overcomes the defects of conventional plastics.

Description

[0001] Technical field:

[0002] The invention relates to the field of polymer material processing, in particular to a negative ion plastic and a preparation method thereof.

[0003] Background technique:

[0004] Negative ions can not only promote the synthesis and storage of vitamins in the human body, but also strengthen and activate the physiological activities of the human body, so it is also called "air vitamin". Impact. For example, after a thunderstorm, the negative ions in the air increase, and people feel comfortable; while in an air-conditioned room, because the negative ions in the air almost disappear after a series of air-conditioning purification treatments and long ventilation ducts, people will feel chest tightness, dizziness, and fatigue if they stay in it for a long time. , Work efficiency and health decline, known as "air conditioning syndrome".

[0005] At present, there are many types of negative ion powders on the market, and the particle size distribut...

[0034]

[0035] (1) According to the composition of the raw materials described in Table 1, put all the raw materials together into a high-speed mixer and mix for 3-5 minutes.

[0036] (2) Add the mixed materials into the intermeshing parallel co-rotating twin-screw extruder through the main feeding hopper, and obtain negative ion plastic particles through melting, extrusion, and pelletizing; wherein, the temperature of the barrel of the extruder is 220-240 ℃, the screw speed is 400~500r / min, and the vacuum degree is -0.04~-0.1MPa.

[0037] (3) Put the negative ion plastic particles into a drying oven with a temperature of 85±5° C. to dry for 2 to 4 hours, then add them to a high-speed mixer and mix for 2 to 5 minutes to obtain negative ion plastics.

[0038] The negative ion plastic is broken in the liquid nitrogen environment, and the cross-section is evacuated and gold-sprayed, and a digital scanning electro...
