Natural high-efficiency controllable initiation-type oxygen-absorbing functional master batch, and preparation method thereof

Abstract

The invention discloses a natural high-efficiency controllable initiation-type oxygen-absorbing functional master batch, and a preparation method thereof, and belongs to the technical field of novel functional material. The natural high-efficiency controllable initiation-type oxygen-absorbing functional master batch comprises 0.5-10wt% of a carrier embedding material / natural antioxidant / oxygen absorbing auxiliary agent assembly, 0-10wt% of a slow release filler, 0.5-2wt% of an auxiliary agent, and 78-99wt% of resin master batch. The preparation method comprises following steps: the resin master batch, the auxiliary agent, the carrier embedding material / natural antioxidant / oxygen absorbing auxiliary agent assembly and the slow-release filler are uniformly mixed, and are subjected to melt blending, extruding and dicing so as to obtain the master batch with oxygen absorbing function. The adopted raw materials are safe and nontoxic; the antioxidant is a natural compound; compound anti-oxidant synergistic effect is achieved; the oxygen absorbing auxiliary agent is capable of increasing oxygen absorbing activity; and a plurality of physiological functions beneficial for human bodies areachieved. The oxygen absorbing efficiency is high; no transition metal is needed; no oxygen absorbing by-product is generated; in drying storage, oxygen absorbing is avoided. The master batch with oxygen absorbing function can be used for protective packages of oxygen sensitive products such as fruit juice drink, grease products, health care products, medicines, and medical devices.

Description

technical field [0001] The invention belongs to the technical field of new functional materials, and in particular relates to a natural high-efficiency controllable initiation type oxygen-absorbing functional masterbatch and a preparation method thereof. Background technique [0002] Oxygen-sensitive special products such as juice drinks, oil products, health care products, medicines, and medical devices need to be stored under almost anaerobic conditions. Traditional vacuuming and air conditioning methods will leave 2% to 3% of oxygen residues , so oxygen-absorbing packaging appeared. Commonly used inorganic oxygen-absorbing agents include iron-based oxygen-absorbing agents, sulfite-based oxygen-absorbing agents, and hydrogenated oxygen-absorbing agents. , Leakage, unable to microwave heating, unable to pass metal detection, high cost and other problems; organic synthetic antioxidants such as butylated hydroxytoluene (BHT), tert-butyl p-hydroxyanisole (BHA), tert-butyl hydr...

Problems solved by technology

[0002] Oxygen-sensitive special products such as juice drinks, oil products, health care products, medicines, and medical devices need to be stored under almost anaerobic conditions. Traditional vacuuming and air conditioning methods will leave 2% to 3% of oxygen residues , so oxygen-absorbing packaging appeared. Commonly used inorganic oxygen-absorbing agents include iron-based oxygen-absorbing agents, sulfite-based oxygen-absorbing agents, and hydrogenated oxygen-absorbing agents. , Leakage, unable to microwave heating, unable to pass metal detection, high cost and other problems; organic synthetic antioxidants such as butylated hydroxytoluene (BHT), tert-butyl p-hydroxyanisole (BHA), tert-butyl hydroquinone (TBHQ), etc. have potential toxicity; oxygen-absorbing resin products often need to be catalyzed by adding excessive metals, and toxic by-products are produced after oxygen absorption and chemical bonds are broken. The above-mentioned traditional oxygen absorbing products all have the problem that the oxygen absorbing process is uncontrollable. As long as there is oxygen in the environment, the oxygen absorbing reaction will start, which will cause difficulties in product preservation and practical application.
