Embodiment 1

[0023] The preparation method of a kind of environment-responsive functional plastic master batch according to the present invention, the preparation process is as follows: the formula ratio is calculated by mass percentage:

[0024] (1) Mix 50% PP (polypropylene), 10% sodium chlorite, and 2% dioctyl phthalate in a high-speed mixer at 500 rpm for 5 minutes;

[0025] (2) Add 3% simethicone, 1% paraffin, 10% talc, and 8% calcium carbonate to step (1), and mix in a high-speed mixer at 800 rpm for 2 minutes. Put the above mixture into a twin-screw extruder, control the temperature at 150-190°C, then put the product into a granulator for granulation.

[0026] Using this masterbatch as a raw material can be used in the field of environmentally responsive daily-use plastic products and film products.

Embodiment 2

[0028] The preparation method of a kind of environment-responsive functional plastic master batch according to the present invention, the preparation process is as follows: the formula ratio is calculated by mass percentage:

[0029] (1) 70% LDPE (low-density polyethylene), 0.2% sodium chlorate, 5% sodium perchlorate, 3% PE wax (polyethylene wax), mixed 2 minutes at 1000 rpm in a high-speed mixer;

[0030] (2) Add 5% paraffin and 20% kaolin into step (1), and mix for 3 minutes in a high-speed mixer at 500 rpm. Put the above mixture into a twin-screw extruder, control the temperature at 130-220°C, then put the product into a granulator for granulation.

[0031] Using this masterbatch as a raw material can be used in fields such as environment-responsive functional plastic masterbatch products and hollow containers.

Embodiment 3

[0033] The preparation method of a kind of environment-responsive functional plastic master batch according to the present invention, the preparation process is as follows: the formula ratio is calculated by mass percentage:

[0034] (1) 80% LLDPE (linear low-density polyethylene), 1% citric acid, 1% stearic acid, 1% zinc stearate, 2% simethicone oil, in a high-speed mixer at 1000 rpm Mix for 6 minutes;

[0035] (2) Add 5% simethicone, 1% dioctyl phthalate, 5% kaolin, and 5% silicon powder to step (1), and mix in a high-speed mixer at 500 rpm for 2 minutes. Put the above mixture into a twin-screw extruder, control the temperature at 130-220°C, then put the product into a granulator for granulation.

[0036] Using this masterbatch as a raw material, it can be used in fields such as environmentally responsive healthcare, automotive interiors, and home improvement.

Abstract

The invention belongs to the technical field of novel functional materials and particularly relates to a preparation method for an environment-responsive functional plastic masterbatch and an application of the environment-responsive functional plastic masterbatch. The environment-responsive functional plastic masterbatch is characterized by containing the ingredients in percentage by mass: 50% to 85% of carrier polymer, 0.1% to 15% of responsive functional component, 10% to 25% of filler and 5% to 10% of auxiliaries. The preparation method comprises the steps of mixing the carrier polymer, the responsive functional component and the auxiliaries in a high-speed mixer, then, adding the auxiliaries and the filler into the mixture, carrying out mixing in a high-speed mixer, and carrying out granulating by using a twin-screw extruder, thereby preparing the environment-responsive functional plastic masterbatch. The masterbatch is ecologically friendly and environmentally responsive and can be applied to the fields of environment-responsive functional plastic masterbatch products, multifunctional film products, plastic products for daily use, household electrical plastic products, plastic pipes, medical care, automobile interior, household fitment, and the like, and the problems, i.e., low technological content and single function of plastic masterbatch at present can be solved, so that the range of application of functional masterbatch is enlarged.

Description

technical field [0001] The invention belongs to the technical field of new functional materials, and in particular relates to a preparation method and application of an environment-responsive functional plastic masterbatch. The masterbatch is used in various fields such as film products, various hollow containers, daily-use plastic products, home appliance plastic products, plastic pipes, medical care, automotive interior decoration, and home decoration. Background technique [0002] Responsiveness refers to a phenomenon in which active ingredients respond to environmental stimuli, such as pH changes, temperature changes, humidity changes, light changes and other environmental stimuli, often used in drug delivery systems (drug delivery systems), UV light Curing coatings, cosmetics and other fields. At present, the research on responsiveness is mainly concentrated in liquids, and it is necessary to provide responsive groups through specially designed polymers, and such polym...
