Problems solved by technology

[0004] For cream cosmetics, different packaging materials have a greater impact on the performance of the cosmetics. The content of methyl salicylate in the preparations packaged in metal aluminum tubes has the fastest decline rate, while plastic hoses and composite hoses are relatively stable. However, the existing packaging Hose materials have deficiencies in corrosion resistance, stability, mechanical properties, air permeability, etc., and need to be further improved

Abstract

The invention provides a preparation method of a cream flexible tube packaging material. The preparation method comprises the steps: adding graphite oxide into deionized water and carrying out ultrasonic treatment at the temperature of 30-40 DEG C for 20-30 min, to obtain a dispersed solution; taking the dispersed solution, 0.02-0.04 mol / L silver nitrate and glycerol, mixing, stirring at the temperature of 60-80 DEG C for 20-30 min, then allowing to stand for 1-3 h, and centrifuging and washing to obtain silver-loaded graphene; mixing PE, polycarbonate and epoxy resin, carrying out a reactionfor 10-20 min at the temperature of 100-120 DEG C, followed by adding glycerol, polypropylene fibers, glass fibers, nano-attapulgite and nano-silica, and continuing to carry out stirring reaction for20-40 min; and dropping the temperature to 70-80 DEG C, adding silver-loaded graphene, putting into a twin-screw extruder together, and carrying out melting extrusion granulation to obtain the cream flexible tube packaging material.

Description

technical field [0001] The invention relates to the technical field of preparation of tube packaging materials, in particular to a preparation method of cream tube packaging materials. Background technique [0002] There are many kinds of cosmetics with different functions, but in terms of their external form and packaging adaptability, most of them are liquid, emulsion or paste, which do not have a distinctive appearance. They must be expressed through exquisite and unique packaging design. Out of its own characteristics, in addition to metal, plastic and glass are currently the main cosmetic packaging container materials used. [0003] Although the cosmetics packaging market has always been dominated by glass, the diversity and plasticity of plastics make plastics an increasingly popular packaging material. Moreover, the poor impact resistance of glass bottles, the high cost of fragile filling, and the complicated molding process also limit the application of glass bottle...
