Description
Technical Field
The invention relates to the technical field of plastic coloring, in particular to color master batches with an infrared reflection effect, a sun-shading film and a preparation method thereof.
Background
Among the total radiant energy of sunlight, more than 99% is distributed in the visible region and the red and ultraviolet regions, the visible region accounts for about 50% of the total radiant energy of the sun, and the infrared region accounts for about 43%. The infrared ray has low frequency and insufficient energy, and can only penetrate into the gaps between atoms and molecules, so that the vibration of the atoms and the molecules is accelerated, the distance is enlarged, and the thermal motion energy is increased.
Generally, a tent, a sunshade film, an agricultural film and the like used outdoors do not have an infrared ray reflection function, and absorb a large amount of infrared rays under the irradiation of sunlight, so that not only is the temperature of the film itself increased, but also the temperature in the tent or the sunshade is high, and the sunshade effect is greatly reduced.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a sun-shading film with an infrared reflection effect.
The purpose of the invention is realized by the following technical scheme:
a sun-shading film with an infrared reflection effect comprises the following components in percentage by weight:
cooling pigment yellow 16-20%;
0.4-0.6% of cooling pigment red;
5.1-7.6% of cooling pigment black;
9.2-11.8% of titanium dioxide;
3.4-4.6% of an ultraviolet absorbent;
8.4-9.6% of a light stabilizer A;
4.4-5.6% of an antioxidant;
45-48% of polyethylene resin.
A sun-shading film with an infrared reflection effect is composed of the color master batches and polyethylene plastics in a ratio of 1: 24.
A method for preparing a sun-shading film with an infrared reflection effect comprises the following steps:
s1, conveying the cooling pigment yellow, the cooling pigment red, the cooling pigment black, the titanium dioxide, the ultraviolet absorbent, the light stabilizer A, the antioxidant and the polyethylene resin into a stirrer at normal temperature and normal pressure, stirring at the speed of 100-120 r/min for 30 minutes, and uniformly stirring and mixing to form a mixture;
s2, putting the mixture into a double-screw extruder for extrusion granulation, wherein the extrusion temperature is controlled to be 190-210 ℃;
s3, extruding to form material strips, cooling the material strips through a water tank, and then granulating in a granulator to obtain anti-aging cooling master batches;
s4, adding the anti-aging cooling master batch into polyethylene plastic according to the proportion of 4%, plasticizing and melting the raw materials through an extruder at 210-230 ℃, extruding the mixture through a T-shaped structure forming die at 250-280 ℃, casting the mixture in a sheet shape onto the roll surface of a cooling roller which rotates stably, cooling and shaping a diaphragm on the cooling roller, and rolling the product after traction and edge cutting to obtain the sunshade film.
Sunlight is an electromagnetic wave, which is divided into visible light 400nm-700nm and invisible light. The invisible light mainly comprises ultraviolet rays and infrared rays of 700 and 2500 nm. Approximately 5% of the solar radiation that strikes the surface of an object is ultraviolet light, which can be absorbed by ultraviolet absorbers, providing protection for the product within the sun shade film. At the same time, nearly 50% is infrared, and the result of infrared irradiation is absorption of radiation and accumulation of additional heat. The color, gloss and other mechanical properties of the product deteriorate over time upon exposure to light, and the temperature of the surface of the product increases considerably over ambient temperatures. The sun-shading film added with the infrared reflection pigment can effectively reflect infrared rays, and the temperature of a product in the sun-shading film is reduced under illumination, so that the cooling effect is achieved.
The invention has the following beneficial effects: 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 environments such as outdoor forests and the like, can be used in military and civil use, can reduce the surface temperature of products, achieves the effects of energy conservation and environmental protection, and has the characteristics of anti-aging, so that the service life of the products is effectively prolonged.
