Abstract

The invention relates to preparation and application of a medical-stone-based multifunctional plastic master batch, belonging to the technical field of composite materials. The medical-stone-based multifunctional plastic master batch comprises 70-80% of carrier resin, 1-5% of medical stone, 5-10% of filler and 15-24% of assistant. The preparation method comprises the following steps: uniformly mixing the carrier resin and medical stone, adding the filler and assistant, and granulating by a granulator to obtain the master batch. The plastic master batch has the advantages of simple preparation process and low cost, and is suitable for industrial production. Meanwhile, the master batch has the multiple functions of environment friendliness, bacterial resistance, health care, toxic substance adsorption and the like, can be used in the fields of environment-friendly water treatment, medical care, automobile interior decoration, home decoration and the like, can solve the problem of no function or single function in the existing plastic master batch, and has wider application range.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to the preparation and application of a multifunctional plastic masterbatch based on medical stone. The masterbatch is used for film products, such as single-layer film, multi-layer co-extruded film, biaxially oriented film, heat-shrinkable film, various hollow containers, such as water dispenser barrels, mineral water bottles, etc., and various packaging materials. Background technique [0002] Medical stone is a compound mineral that is non-toxic and harmless to organisms and has certain biological activity. Active, has the ability to adsorb pigments and bacteria, and can absorb free ions in water. In addition, medical stone in water can release K, Ca, Mg and Si, Fe, Zn, Cu, Mo, Se, Mn, Sr, Ni, V, Li, Co, Cr, which are useful to human body and organisms. , I, Ge, Ti and other trace elements, medical stone can also dissolve amino acids necessary for the hu...
