Problems solved by technology

[0003] Generally, tents, sunshade films, and agricultural films used outdoors do not have the function of infrared reflection, and will absorb a large amount of infrared rays under the sunlight. Not only the temperature of the film itself will rise, but also the temperature inside the tent or sunshade will be very high. The effect of sunshade is greatly reduced

Embodiment 1

[0025] Under normal temperature and pressure, 16kg of cooling pigment yellow, 0.4kg of cooling pigment red, 5.1kg of cooling pigment black, 9.2kg of titanium dioxide, 3.4kg of ultraviolet absorber, 8.4kg of light stabilizer A, 4.4kg of antioxidant and polyethylene resin 45kg is sent to the mixer at a stirring speed of 100-120r / min for 30 minutes, stirring and mixing evenly to form a mixture. The mixture is put into a twin-screw extruder for extrusion granulation, and the extrusion temperature is controlled at 190-210°C. Extrude to form strands, then cool the strands through a water tank and enter the pelletizer for granulation to obtain the anti-aging and cooling masterbatch of the present invention.

Embodiment 2

[0027] Under normal temperature and pressure, 18kg of cooling pigment yellow, 0.5kg of cooling pigment red, 6.4kg of cooling pigment black, 10kg of titanium dioxide, 4kg of ultraviolet absorber, 9kg of light stabilizer A, 5kg of antioxidant and 46kg of polyethylene resin are sent to 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, and the extrusion temperature is controlled at 190-210°C. Extrude to form strands, then cool the strands through a water tank and enter the pelletizer for granulation to obtain the anti-aging and cooling masterbatch of the present invention.

Embodiment 3

[0029] Under normal temperature and pressure, 20kg of cooling pigment yellow, 0.6kg of cooling pigment red, 7.6kg of cooling pigment black, 11.8kg of titanium dioxide, 4.6kg of ultraviolet absorber, 9.6kg of light stabilizer A, 5.6kg of antioxidant and polyethylene resin 48kg is sent to the mixer, the stirring speed is 100-120r / min, 30 minutes, stirring and mixing evenly to form a mixture. The mixture is put into a twin-screw extruder for extrusion granulation, and the extrusion temperature is controlled at 190-210°C. Extrude to form strands, then cool the strands through a water tank and enter the pelletizer for granulation to obtain the anti-aging and cooling masterbatch of the present invention.

Abstract

The invention discloses a sun-shading film with an infrared reflection effect. The sun-shading film is composed of the following components in percentage by weight: 16-20% of cooling pigment yellow; 0.4 to 0.6 percent of cooling pigment red; 5.1%-7.6% of cooling pigment black; 9.2 to 11.8 percent of titanium dioxide; 3.4%-4.6% of an ultraviolet light absorber; 8.4%-9.6% of a light stabilizer A; 4.4%-5.6% of an antioxidant; and 45 to 52.8 percent of polyethylene resin. According to the sun-shading film, the sun-shading film prepared from the anti-aging cooling master batch has the function of reflecting infrared rays, can be widely applied to tents and sun-shading nets used in outdoor forests and other environments, can be used in military and civil applications, can reduce the surface temperature of products, achieves energy-saving and environment-friendly effects, and can effectively prolong the service lives of the products due to the anti-aging characteristic of the sun-shading film.

Description

technical field [0001] The invention relates to the technical field of plastic coloring, in particular to a color masterbatch with an infrared reflection effect, a sunshade film and a preparation method thereof. Background technique [0002] Of the total radiant energy of sunlight, more than 99% are distributed in the visible light region and the red and ultraviolet regions. The visible light region accounts for about 50% of the total solar radiation energy, and the infrared region accounts for about 43%. Infrared rays have a low frequency and insufficient energy, and can only penetrate into the gaps between atoms and molecules, which will accelerate the vibration of atoms and molecules, widen the distance, and increase the energy of thermal motion. [0003] Generally, tents, sunshade films, and agricultural films used outdoors do not have the function of infrared reflection, and will absorb a large amount of infrared rays under the sunlight. Not only the temperature of the ...
