Description

technical field

[0001] The invention relates to the technical field of petrochemical industry, in particular to a diesel cleaning life extension material. Background technique

[0002] Diesel is a very important vehicle fuel in our country. There are a large amount of reserves in both the military and the local government. During the storage period of diesel, the chemical substances in it will gradually change with the growth of time. It will gradually polymerize into compounds with larger molecular weight to form colloids, and finally form sludge after further polymerization; apparently, the color of diesel oil will gradually become darker, the viscosity will increase, and the acidity, actual colloids and solid particle pollutants will increase significantly. Cause oil deterioration, so its storage life is often limited. Especially in terms of reserve oil, in order to ensure people's livelihood and stability, a large amount of diesel oil is stored in various military or lo...

Examples

Embodiment 1

[0037]A diesel cleaning life-extending material, characterized in that: it is composed of A component and B component, the A component is liquefied MDI, and the B component is composed of the following raw materials in parts by weight: polyether 330N: 30 parts, Polyether 3628: 50 parts, Foam leveling agent L580: 1 part, Water: 0.6 parts, Polyurethane catalyst A33: 0.7 parts, Polyurethane catalyst T9: 0.4 parts, the weight ratio of A component and B component during foaming is 1:1. The duty cycle of the diesel oil cleaning life extension material is 2%, and the density is 0.005g / cm 3 , Tensile strength 0.08Mpa, elongation at break 200%, and no adverse chemical reactions with diesel. The density of the diesel cleaning life extension material in this embodiment is measured at normal temperature.
