Abstract

The invention discloses a method for making glass microspheres for covering light oil materials. Firstly, the glass microspheres are impregnated with an oil-repellent agent, and then the glass microspheres impregnated with the oil-repellent agent are wrapped with a wrapping varnish; the oil-repellent agent consists of a It is composed of trichlorosilane, dimethyldichlorosilane, toluene, trichlorosilane and deionized water; the wrapping paint is composed of unsaturated polyester resin and ethyl perfluoroalkyl acrylate. The method of the present invention uses a special resin to wrap the surface of the glass microsphere impregnated with an oleophobic agent, so that it has oleophobic and water-repellent properties, is not eroded by light oil, can maintain the original density, and can inhibit the evaporation of light oil Loss, can eliminate the sinking phenomenon caused by the adhesion of too much oil when the surface of ordinary glass microspheres is covered with light oil.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a method for preparing glass microspheres for covering light oil materials. Background technique [0002] Strong evaporation is one of the main properties of petroleum products, especially various light oil products, such as solvent naphtha, gasoline, kerosene, light diesel oil, etc. These types of oils have low density. Under the action of temperature, the molecules on the surface of the liquid gain external energy, easily overcome the gravitational force between the liquids, become oil vapor molecules, leave the liquid surface, and diffuse into the space, which is difficult to recover. Evaporation loss of liquid. Evaporation losses not only result in a reduction in the quantity of oil, but also in quality, especially gasoline. The oil vapor lost to the environment not only causes environmental pollution, but also easily forms a potential fire hazard. [0003] Evaporation ...
