Abstract

The invention relates to the technical field of new material processing, and discloses a preparation method of a corrosion-resistant chemical barrel material. According to the preparation method, nanometer ceramic material modified polypropylene composite plastic is used for preparing a chemical barrel material master batch; chemical reaction between a corrosive medium and the surface of the chemical barrel material is prevented; a interface structure is protected; excellent performances of corrosion resistance, wear resistance, low relative density and the like are realized; the preparationmethod can be used for plastic enhancement, and the effect of promoting plasticization can also be achieved; after being treated and added into the polypropylene blended plastic, the corrosion-resistant chemical barrel material has an excellent reinforcing effect, the material microstructure can greatly improve the corrosion resistance, mechanical properties and aging resistance of blended materials, the corrosion-resistant chemical barrel material can be well dispersed in the blended materials, and the chemical properties are basically kept stable after immersion in corrosive liquid for a long time.

Description

technical field [0001] The invention belongs to the technical field of new material processing, and in particular relates to a preparation method of a corrosion-resistant chemical barrel material. Background technique [0002] Most of the chemical barrels are made of plastic, generally called plastic chemical barrels and plastic chemical barrels. They are developed and blow-molded using scientific formulas. Fading, non-deformation and other aspects meet the packaging index, which is an ideal choice for long-distance transportation of chemical product packaging materials. [0003] With the development of industrialization, the demand for chemical barrels is getting higher and higher. The requirements for chemical barrels are not limited to basic performance. While ensuring beauty, elegance, and convenience, the most important thing is the safety during packaging, transportation, and use. Often, the barrels store highly irritating and corrosive chemicals, so corrosion resist...
