Abstract

The invention discloses a corrosion preventing and inhibiting agent for bio-based methanol gasoline and a preparation method of the corrosion preventing and inhibiting agent. The corrosion preventing and inhibiting agent consists of the following ingredients: 30-40% of metal corrosion prevention ingredient, 30-35% of passivation and chelation ingredient and 25-40% of anti-oxidative corrosion inhibition ingredient; and the corrosion preventing and inhibiting agent product is prepared through uniformly mixing the three functional ingredients at normal temperature. According to the corrosion preventing and inhibiting agent and the preparation method of the corrosion preventing and inhibiting agent, cleanable, environmental-friendly, reproducible and degradable petroleum yeast fatty acid is selected as the main raw material of a cheap additive, so that the energy is saved and the emission is reduced; and compared with the prior art, the corrosion preventing and inhibiting agent is low in cost, non-toxic, free of pollution, low in dosage and remarkable in corrosion preventing and inhibiting effect and cannot cause secondary pollution to the environment. Proved by results of tests on multiple metals, such as brass 59#, red copper, aluminum, steel 45#, zinc and carburetor materials, the corrosion preventing and inhibiting agent has a very obvious corrosion prevention effect; and shown by overhauling, after the corrosion preventing and inhibiting agent is used, the corrosive damage to cylinders, pumps and oil way systems is equivalent to that when commercial gasoline is used, and the oil way systems and carburetors are free of an obvious corrosion phenomena.

Description

technical field [0001] The invention relates to the field of alternative fuels for alcohols, in particular to an anti-corrosion and corrosion inhibitor which mainly uses biomass energy and can be blended with bio-alcohols in a high proportion. Background technique [0002] For a long time, gasoline and diesel have been the main fuels for various types of motor vehicles. This usage pattern is increasingly restricted by serious environmental pollution and increasingly scarce resources. In order to improve this dilemma, a variety of energy alternatives have been adopted at home and abroad. However, if these alternatives are to be popularized on a large scale, there are serious defects. In recent years, as the international oil price continues to hover at a high level, the promotion, application and research process of alternative alcohol-ether fuels at home and abroad have been accelerated. According to the implementation of the strategic policy of energy substitution promulga...
