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...

AI Technical Summary

Problems solved by technology

[0005] At present, there are many types of negative ion powders on the market, and the particle size distribution of the powders is also wide, ranging from micron to nanometer; the efficiency of negative ion powder releasing negative ions is relatively stable, but it is added to plastics or other matrix materials as a modified additive. The efficiency of releasing negative ions changes greatly during the time, because the negative ion powder has the problem of poor dispersion and easy agglomeration in the plastic matrix, which affects the appearance and even physical properties of the molded plastic parts.
