Abstract

The invention discloses a diesel oil cleaning and life-prolonging material consisting of a component A and a component B, wherein the component A is liquefied MDI, and the component B consists of the following raw materials in parts by weight: 30-50 parts of polyether 330N, 50-70 parts of polyether 3628, 1-3 parts of a foaming equalizing agent L580, 0.6-0.8 part of water, 0.7-0.9 part of a polyurethane catalyst A33 and 0.4-0.6 part of a polyurethane catalyst T9; and the weight ratio between the component A and the component B is 1:1 in foaming. The diesel oil cleaning and life-prolonging material disclosed by the invention is cheap in price and easy to produce, the problem that existing diesel oil is easy to go bad in a long-term storage process can be solved, the increase of acidity, existent gum and solid particulate pollutant indexes of oil products can be inhibited, and the market blank can be filled.

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...
