Problems solved by technology

[0009] Tourmaline powder and negative ion powder are both polar inorganic powders. They have poor compatibility with polyethylene. Direct addition will lead to a serious decline in material performance and cannot meet the requirements of the fuel tank; the combination of tourmaline powder and negative ion powder with polyethylene matrix Not good, polyethylene plays a shielding role in the material, and cannot quickly conduct micro-heat changes in the environment, making the piezoelectric and pyroelectric effects of tourmaline invalid; in addition, due to the uneven dispersion of tourmaline powder and anion powder, it also seriously affects Catalytic effect on diesel

Abstract

The invention discloses an oil-saving rotational-molding diesel oil tank material and a preparation method thereof. The formula of the oil-saving rotational-molding diesel oil tank material comprises the components in mass percent that: 50 percent of linear low density polyethylene, 21 to 47.7 percent of irradiation high density polyethylene; 1 to 10 percent of tourmaline powder, 1 to 10 percent of negative ion powder, 0.1 to 5 percent of antistatic agent, 0.1 to 2 percent of antioxidant and 0.1 to 2 percent of flatting agent. Moreover, the oil-saving rotational-molding diesel oil tank material, which meets the technological requirements of rotational-molding processing, can reach the effect of saving 2 to 5 percent of oil as compared with the prior diesel oil tank when made into an automobile diesel oil tank; moreover, because the preparation method is simple and easy to implement, the oil-saving rotational-molding diesel oil tank material is easy to realize batch production.

Description

Technical field [0001] The invention belongs to the field of chemical industry and relates to a fuel-saving rotomolding diesel fuel tank material and a preparation method thereof. Background technique [0002] Today, when the concept of environmental protection and conservation is advocated, reducing automobile fuel consumption and carbon dioxide emissions has been the goal that people have been pursuing. One of the important technical means is to increase fuel combustion efficiency to achieve fuel saving. The fuel tank is the main fuel storage component of a car. Currently, there are the following methods to improve the fuel tank to save fuel: [0003] 1. The fuel is heated by additional devices. For example, CN2323996Y announced a method of placing a heat exchanger in the fuel tank, using automobile exhaust gas to heat the fuel, and reducing start-up consumption to save fuel. CN2586606Y announced a method of adding a partition in the fuel tank, adding a radiator and other addit...
