Abstract

The invention relates to the field of plastic film light scattering materials, and specifically relates to a light scattering inorganic microsphere used for a crop plastic shed film and a preparationmethod. The light scattering inorganic microsphere used for the crop plastic shed film is prepared and obtained by the method comprising the following steps: after grinding glass to form a glass finepowder, blowing the glass fine powder with a flame in a spheroidizing furnace to form spherical glass beads; mixing and adding a mica powder, an acid liquor and the spherical glass beads into a jet machine, accelerating through the jet machine so that a mica layer is stripped, forming surface defect micropores in the spherical glass beads, and embedding the stripped mica layer at the defect positions of the micropores; then filtering and drying, and welding mica to the surfaces of the stripped beads through further irradiation of a laser beam, using a sand mill to grind and remove corner angles so as to form the light scattering inorganic microsphere provided with a spherical core which is the glass bead and layered mica on the surface. The prepared and obtained inorganic microsphere has excellent dispersibility in the plastic shed film.

Description

technical field [0001] The invention relates to the field of light-scattering materials for plastic films, in particular to light-scattering inorganic microspheres used for crop plastic shed films and a preparation method. Background technique [0002] The application of inorganic mineral powders as fillers in papermaking and plastics has been very mature. If used in plastic pipes, sheets, films, hollow and injection molding products, it can improve the tensile strength, ring stiffness, flexibility, shrinkage, flame retardancy, heat resistance and barrier properties of plastic products. [0003] Mica can improve the optical properties of plastics, and mica chips have the functions of reflecting, scattering infrared rays, absorbing and shielding ultraviolet rays. Adding mica powder to the agricultural film can block the loss of infrared light to the outside, and can also scatter ultraviolet light to improve the thermal insulation effect of greenhouses and plastic films.
