Description
Technical Field
The invention belongs to the field of agricultural films, and particularly relates to a tourmaline heat radiation film and a preparation method thereof.
Background
The air temperature is an important factor affecting the growth of crops, fishes, shrimps and crabs, and particularly in winter, the low-temperature weather has great negative influence on the planting industry and the aquaculture industry. Low temperature cold injury, slow plant growth, local necrosis, low fruit setting rate, and reduced yield and quality. The change of air temperature directly affects the life of aquatic products, affects the ingestion, reproduction and the like of the aquatic products, and at low temperature, the metabolism of fish is obviously reduced, appetite is lost, ingestion is stopped, and growth is slowed or even stopped. The method is a particularly important work for carrying out heat preservation and temperature increase on crop and aquatic products aiming at winter with low temperature, particularly northern area climate.
At present, most of films used for agricultural heat preservation greenhouses are multilayer plastic films, and the plastic films have good heat preservation effect, and heat-insulating air is filled in the films, so that even in cold seasons, the temperature in the film greenhouses can be kept very high due to the heating effect of sunlight irradiation in the daytime, and the growth of crops is facilitated. However, when the sunlight irradiates at night or not, the temperature in the greenhouse is reduced greatly due to heat dissipation under the condition of large day-night temperature difference, and the growth of crops is not facilitated. The heat dissipation in the shed is mainly caused by far infrared radiation effect, and the wavelength of the ground infrared radiation is mainly in the region of 7-14 mu m.
Tourmaline (tourmaline) is used as a far infrared heating material, 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 (bioelectricity). The tourmaline can emit far infrared rays with the wavelength of 4-14 mu m and the normal emissivity higher than that of the common far infrared material at normal temperature (the normal emissivity of the tourmaline is higher than 0.92). Based on the method, tourmaline is used as a heating material to be added into the functional agricultural film, so that the heat preservation performance of the agricultural film is expected to be enhanced. Tourmaline is a general term for tourmaline group minerals, has complex chemical composition, is a silicate mineral with a cyclic structure of aluminum, sodium, iron, magnesium and lithium characterized by boron, and has [ BO ] besides silicon oxygen backbone 3 ] 3- Anionic groups of the general formula (Na, ca) (Mg, fe, mn, li, al) 3 Al 6 (Si 6 O 18 )(BO 3 ) 3 (OH,F) 4 . Besides releasing far infrared rays, tourmaline has unique functions of piezoelectricity, thermoelectricity, anions and the like, is widely applied to the fields of environmental protection, electronics, medicine, chemical industry, light industry, building materials and the like, and becomes a novel industrial mineral with high added value. The research shows that the functions of tourmaline such as electric effect, negative ion release and the like can be enhanced along with the reduction of the particle size of the powder, and a series of excellent surface and interface properties are shown. Compared with the related researches on other characteristics of tourmaline, the theoretical research on the utilization and development of functions such as infrared radiation characteristics of the tourmaline is far behindIn actual production, a certain corresponding relation may exist between the average particle size of tourmaline powder and the infrared radiation characteristic of tourmaline. However, as the particle size of the powder is reduced, the specific surface area is increased, and the specific surface energy is increased, the agglomeration phenomenon is very easy to generate in the preparation and processing processes, so that tourmaline is not easy to uniformly disperse in the compounding process with other components, and the comprehensive performance and the service life of the composite material are affected.
