Impact-resistant antistatic polyethylene material and preparation method thereof

Abstract

The invention discloses an impact-resistant antistatic polyethylene material and a preparation method thereof, and relates to the technical field of new materials. Metallized glass fibers and modified high-density polyethylene emulsion are prepared, the metallized glass fibers are formed by ultrafine glass fibers wrapped by nanosheets formed after layered niobate interlayer separation, and after current intervention is removed after layered niobate interlayer separation, the metallized glass fibers are mutually adsorbed due to static electricity. The structure has the electrical conductivity of the metal-plated glass fibers and also has the environmental protection property of a niobate layered structure, and the interlayer metal-plated glass fiber structure is tightly combined with the niobate layered structure. The impact-resistant antistatic polyethylene material prepared by the invention has the characteristics of easy molding, low cost, corrosion resistance, impact resistance, antistatic property, environmental protection and energy saving.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to an impact-resistant and antistatic polyethylene material and a preparation method thereof. Background technique [0002] The marine oil is heavy oil, the composition of heavy oil is more complicated than that of light fuel oil, and the carbon content is as high as about 85%. It is mainly composed of asphaltenes and colloids. Metals, non-metals, ash and sulfur, high freezing point and viscosity, the existing pipelines used for ships are mostly metal materials, the weight of metal materials is high, which increases the weight of the ship, and it is suitable for heavy oil with high viscosity and long-term use The problem is that the pipes made of metal materials do not take into account the aging and cleaning problems of the pipes.

AI Technical Summary

Problems solved by technology

[0002] The marine oil is heavy oil, the composition of heavy oil is more complicated than that of light fuel oil, and the carbon content is as high as about 85%. It is mainly composed of asphaltenes and colloids. Metals, non-metals, ash and sulfur, high freezing point and viscosity, the existing pipelines used for ships are mostly metal materials, the weight of metal materials is high, which increases the weight of the ship, and it is suitable for heavy oil with high viscosity and long-term use Problem, pipes made of metal materials do not take into account the aging and cleaning of pipes

[0003] Partial replacement of metal materials with resin can reduce the weight of the pipe itself, but high-density polyethylene is a highly crystalline, non-polar thermoplastic resin that does not absorb moisture and has good water vapor resistance, and can be used for packaging purposes. Very good electrical properties, especially the high dielectric strength of the insulation, make it very suitable for wires and cables, but the current high-density polyethylene materials have very poor fire resistance and air cracking resistance. For high-temperature air environments, the performance of the material It cannot meet the requirements and cannot be used, and the surface smoothness of high-density polyethylene is lower than that of metal, which is more likely to cause adhesion and blockage

[0004] The problems existing in the inner wall of the existing ship pipelines are that it has not considered whether to replace the pipeline with other materials to reduce the weight of the pipeline, and has not considered the prevention of fuel backflow, anti-aging and self-cleaning of the fuel engine, etc.
