Natural antibacterial anti-aging rubber material and preparation method thereof

Abstract

The invention provides a natural antibacterial anti-aging rubber material. The rubber material is prepared from, by weight, 65-85% of a rubber, 2.5-5% of a botanical extract, 5-15% of nano loess, 1.5-3% of celery seed oil, 1.5-3% of octadecyl dihydroxyethyl amine oxide, 1.5-3% of zinc oxide and 3-6% of sulfur by various processing methods. The rubber material gains multiple functions of natural bacteria resistance, mildew resistance, antioxidation, ultraviolet resistance, far infrared health care and incense increase, can be used for manufacturing rubber products, expands the antimicrobial spectrum of a bactericidal anti-corrosion system, has high inhibitory rate, good antibacterial property, lasting bacteria resistance, excellent resistance to aging, better mechanical properties and longer service life. Meanwhile, the far-infrared radiation effects can play a role in health care, as well as self-cleaning, ambient air purification and elimination of smell. The material is beneficial to human health and environment-friendly, and has expanded scope of application and great social, ecological and economic benefits.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a natural antibacterial and aging-resistant rubber material and a preparation method thereof. Background technique [0002] Rubber is a high-elastic high-molecular compound that is insulating and insulates air and water, and is made by processing the latex of plants such as rubber trees. It is divided into natural rubber and synthetic rubber. Due to its stable chemical structure, rubber material has the advantages of high elasticity, good wear resistance and acid and alkali corrosion resistance. It is not only widely used in transportation, construction, machinery, electronics, cables, sports, office and other fields, but also with the The deepening of modification research is rapidly expanding to clothing, food, housing, transportation, medical treatment and daily necessities that are in close contact with the human body. However, rubber products are prone to aging wh...

Problems solved by technology

However, natural antibacterial agents are usually extracted from a plant, animal or organism. The antibacterial ingredients are relatively single, and the antibacterial spectrum is narrow. The compatibility between it and rubber is poor, and it is easy to cause problems such as agglomeration and uneven dispersion. Antibacterial ingredients are easy to precipitate during use, and the antibacterial effect cannot last

In addition, the existing antibacterial agents cannot have both antibacterial, anti-aging and health care functions. In order to achieve the anti-aging indicators required by rubber products, adding antioxidants is an effective means to prevent oxidation of rubber products.

However, most of the known antioxidants are small molecular compounds with certain toxicity, which tend to gradually precipitate on the surface of rubber products under the action of sunlight, oxygen and heat, which are prone to failure and hidden health and safety hazards.
