Description
Technical Field
The invention belongs to the field of agricultural films, and particularly relates to a tourmaline thermal radiation film and a preparation method thereof.
Background
The air temperature is an important factor influencing the growth of crops, fishes, shrimps and crabs in aquatic products, and particularly brings great negative effects on the planting industry and the aquaculture industry in winter and in low-temperature weather. Low temperature cold damage, slow plant growth, local necrosis, low fruit setting rate, and low yield and quality. The change of the temperature directly affects the life of the aquatic products and the ingestion, the reproduction and the like of the aquatic products, and at low temperature, the metabolism of the fish is obviously reduced, the appetite is lost, the ingestion is stopped, the growth is slowed down, and even the growth is stopped. Aiming at low temperature in winter, particularly in northern regional climate, the heat preservation and temperature increase of crop aquatic products is a particularly important work.
At present, most of films used for agricultural heat-preservation greenhouses are multilayer plastic films, because the plastic films have good heat-preservation effect, and the films are filled with heat-insulation air, the film greenhouse can keep high temperature even in cold seasons and due to the heating effect of sunlight irradiation in the daytime, and the growth of crops is facilitated. However, at night or without sunlight irradiation, under the condition of large day-night temperature difference, the temperature in the greenhouse is greatly reduced due to heat dissipation, and the growth of crops is not facilitated. The heat dissipation in the shed is mainly caused by the far infrared radiation effect, and the wavelength of ground infrared radiation is mainly in the area of 7-14 mu m.
Tourmaline (tourmaline) is one of far infrared heating materials, and can absorb and store solar energy, convert the solar energy into electric energy (bioelectricity) and heat energy (far infrared ray) and release the electric energy and the heat energy. The tourmaline can emit far infrared rays with the wavelength of 4-14 mu m and the normal emissivity higher than that of common far infrared materials (the normal emissivity of the tourmaline is higher than 0.92). Based on the above, tourmaline is used as a heating material to be added into the functional agricultural film, and the heat preservation performance of the agricultural film is hopefully enhanced. Tourmaline is a general term for minerals of tourmaline familyThe silicate minerals having a complex chemical composition and having a cyclic structure of aluminum, sodium, iron, magnesium, and lithium characterized by containing boron include [ BO ] in addition to the silica skeleton3]3-An anionic group having a general formula of (Na, Ca) (Mg, Fe, Mn, Li, Al)3Al6(Si6O18)(BO3)3(OH,F)4. In addition to releasing far infrared rays, tourmaline also has unique functions of piezoelectricity, pyroelectricity, negative ions and the like, is widely applied to the fields of environmental protection, electronics, medicines, chemical industry, light industry, building materials and the like, and becomes a novel industrial mineral with high added value. Researches find that the electric effect, negative ion release and other functions of the tourmaline tend to be enhanced along with the reduction of the powder particle size, and a series of excellent surface and interface properties are displayed. Compared with the related research of other characteristics of the tourmaline, the theoretical research on the utilization and development of functions such as the infrared radiation characteristic of the tourmaline is far behind the actual production, and a certain corresponding relation may exist between the average particle size of tourmaline powder and the infrared radiation characteristic of the tourmaline. However, as the particle size of the powder is reduced, the specific surface area is increased, the specific surface energy is increased, and agglomeration is easily generated in the preparation and processing processes, so that the tourmaline is not easy to be uniformly dispersed in the compounding process with other components, thereby affecting the comprehensive performance and the service life of the composite material.
Disclosure of Invention

According to one aspect of the invention, the tourmaline thermal radiation film comprises, by mass, 0.5-20% of tourmaline, 0.0015-1% of a modifier and 70-99% of a polymer matrix; the modifier is one or the combination of more than one of phenolic resin, amino resin, alkyd resin, epoxy resin, acrylic resin, silane coupling agent and titanate coupling agent; the polymer matrix is one or more of polyolefin, poly halogenated olefin, polyester and polyamide. The modifier is used for modifying the surface of the tourmaline to realize the ultrafine grinding of the tourmaline, and the use of the modifier effectively improves the dispersibility of the ultrafine ground tourmaline, so that the tourmaline can be uniformly dispersed in other membrane materials, and the membrane material has good uniformity and constructability. The infrared radiation wavelength of the tourmaline is 4-14 mu m, and the infrared radiation wavelength of the ground is covered, so that when the tourmaline thermal radiation film provided by the invention is applied to greenhouse planting, the infrared rays emitted by the tourmaline in the tourmaline thermal radiation film can compensate the energy lost due to the infrared radiation of the ground in a greenhouse, and in addition, the specific oxygen anion release function of the tourmaline can increase the concentration of the oxygen anions in the greenhouse, thereby achieving the beneficial effects of sterilization and deinsectization.

Example 1
In the embodiment, tourmaline powder with D50 of 1 μm is subjected to ultrafine grinding, sanding treatment is carried out on the tourmaline powder, and different modifiers are introduced in the sanding process to realize ultrafine grinding of the tourmaline powder. The types and sources of modifiers used in this example are shown in table 1, and the experimental groups are numbered for the different test modifiers.

The far infrared emissivity test and the granularity test are carried out on the tourmaline micropowder obtained after the ultrafine grinding process.
The operation mode of the far infrared emissivity test is as follows: uniformly coating the slurry prepared by the ultrafine grinding process on the surface of the EVA foaming material, putting the coated EVA foaming material into a 50 ℃ oven, drying for about 60 minutes, and taking out. And as a contrast, adding water into the tourmaline powder subjected to the micro-fine grinding treatment to prepare slurry, coating the slurry on the surface of the EVA foaming material, putting the coated EVA foaming material into a 50 ℃ oven, drying for about 60 minutes, and taking out. Measuring the normal far infrared emissivity of the coated EVA foaming material by using an IR-2 dual-band emissivity measuring instrument at the room temperature of 20 ℃, measuring the normal far infrared emissivity of the coated EVA foaming material by using the IR-2 dual-band emissivity measuring instrument, repeatedly testing each sample for 3 times, and taking an average value. The change rate of the normal far infrared emissivity is represented by the ratio of the difference value of the normal far infrared emissivity of the EVA foaming material before and after coating to the normal far infrared emissivity of the EVA foaming material before coating
As shown in table 2, in the experimental group set forth in this example, the particle size of the tourmaline fine powder obtained by the ultra-fine grinding process was significantly reduced, and the particles were significantly refined. It is worth noting that compared with a control group, the normal far infrared emissivity corresponding to the experimental group 2, the experimental group 4, the experimental group 6 and the experimental group 7 is obviously higher, and the particle sizes corresponding to the experimental group 2, the experimental group 4, the experimental group 6 and the experimental group 7 are respectively lower, so that the modification of tourmaline by using amino resin, epoxy resin, silane coupling agent and titanate coupling agent can be proved, the tourmaline particles can be refined, the normal far infrared emissivity of the tourmaline can be effectively improved, and a good modification effect can be achieved.

In addition, the tensile strength of the film product treated by the treatment 5D is higher by comparing the performance data of the films treated by the treatment 5A and the treatment 5D, so that the mechanical performance of the film can be improved by the silicon dioxide, however, even if the infrared transmittance of the treatment 5D is lower, the corresponding temperature in the film shed is lower than the temperature in the film shed corresponding to the treatment 5A, and the reason for the phenomenon is that the raw material for preparing the thermal radiation film treated by the treatment 5A contains tourmaline with the infrared radiation function, so that the prepared thermal radiation film not only prevents the heat loss in the shed, but also can supplement the heat in the shed in the form of infrared radiation, and shows that the temperature in the shed is higher.
