Embodiment 1

[0022] Under normal temperature and pressure, send 10kg of temperature-sensitive pigment vermilion, 10kg of temperature-sensitive pigment brown, 0.8kg of ordinary pigment yellow, 0.2kg of dispersant, 0.2kg of succinic anhydride, 0.2kg of antibacterial agent, and 66.8kg of polyethylene resin into the mixer. The stirring speed is 100-120r / min, 30 minutes, stirring and mixing evenly into a mixture. The mixture is put into a twin-screw extruder for extrusion granulation, the extrusion temperature is controlled at 150-170°C, extruded to form a strand, and then the strand is cooled by a water tank and then enters a pelletizer for granulation to obtain Antibacterial and anti-mildew thermochromic masterbatch.

Embodiment 2

[0024] Under normal temperature and pressure, send 10kg of temperature-sensitive pigment vermilion, 10kg of temperature-sensitive pigment brown, 0.8kg of ordinary pigment yellow, 0.2kg of dispersant, 0.2kg of succinic anhydride, 0.2kg of antibacterial agent, and 66.8kg of polyethylene resin into the mixer. The stirring speed is 100-120r / min, 30 minutes, stirring and mixing evenly into a mixture. The mixture is put into a twin-screw extruder for extrusion granulation, the extrusion temperature is controlled at 150-170°C, extruded to form a strand, and then the strand is cooled by a water tank and then enters a pelletizer for granulation to obtain Antibacterial and anti-mildew thermochromic masterbatch.

[0025] Example 2:

[0026] Under normal temperature and pressure, send 15kg of temperature-sensitive pigment vermilion, 15kg of temperature-sensitive pigment brown, 1.2kg of ordinary pigment yellow, 0.4kg of dispersant, 0.4kg of succinic anhydride, 0.4kg of antibacterial agent...

Embodiment 3

[0028] Under normal temperature and pressure, send 12kg of temperature-sensitive pigment vermilion, 13kg of temperature-sensitive pigment coffee color, 1kg of ordinary pigment yellow, 0.3kg of dispersant, 0.3kg of succinic anhydride, 0.3kg of antibacterial agent, and 70kg of polyethylene resin into the mixer. 100~120r / min, 30 minutes, stir and mix evenly to form a mixture. The mixture is put into a twin-screw extruder for extrusion granulation, the extrusion temperature is controlled at 150-170°C, extruded to form a strand, and then the strand is cooled by a water tank and then enters a pelletizer for granulation to obtain Antibacterial and anti-mildew thermochromic masterbatch.

[0029] In the above examples, the antibacterial agent is formed by mixing isothiazolinone and silver ions. Silver ion antibacterial agents have the characteristics of high efficiency, broad spectrum, long duration, etc., and are non-toxic, odorless, and have no impact on the environment. When a sma...

Abstract

The invention discloses an antibacterial mildew-proof thermochromic master batch and a household article preparation method thereof. The master batch is composed of the following components in percentage by weight: 10-15% of a temperature-sensitive pigment vermilion; 10-15% of a temperature sensing pigment caffeine color; 0.8-1.2% of common pigment yellow; 0.2-0.4% of a dispersing agent; 0.2-0.4% of succinic anhydride; 0.2-0.4% of an antibacterial agent; and 66.8-77.2% of polyethylene resin. The antibacterial mildew-proof product has the main beneficial effects that the antibacterial and mildew-proof product has excellent antibacterial and mildew-proof characteristics, and the color of the product can be changed when the indoor temperature change exceeds 10 DEG C or above, so that on one hand, the life interest is increased, and on the other hand, a warning effect is given out on the temperature change.

Description

technical field [0001] The invention relates to the technical field of plastic coloring, in particular to an antibacterial and anti-mildew thermosensitive color-changing masterbatch and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, health awareness is also gradually enhanced, and people pay more and more attention to the comfort and hygiene conditions of the living environment. It has become a living, learning and working environment that is comfortable, clean, antibacterial, mildew-proof, and prevents the spread of diseases. It has become a hot topic that people pay more and more attention to. However, while people are creating a living environment that is warm in winter and cool in summer for themselves, it also creates favorable conditions for the reproduction and growth of microorganisms. Bacteria and mold are the two main types of microorganisms, with the characteristics of wide variety, wide distribution...
