Swelling preventing and degumming agent for bio-based methanol gasoline and preparation method of swelling preventing and degumming agent

Abstract

The invention discloses a swelling preventing and degumming agent for bio-based methanol gasoline and a preparation method of the swelling preventing and degumming agent. The swelling preventing and degumming agent consists of the following ingredients in percentage by volume: 40-50% of plastic corrosion preventing ingredient, 25-30% of swelling preventing and anti-aging ingredient and 25-30% of degumming preventing ingredient; and the swelling preventing and degumming agent product is prepared through uniformly stirring the three functional ingredients at normal temperature. According to the swelling preventing and degumming agent and the preparation method of the swelling preventing and degumming agent, cleanable, environmental-friendly, reproducible and degradable petroleum yeast fatty acid soap 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 swelling preventing and degumming agent is low in cost, non-toxic, free of pollution, low in dosage and remarkable in swelling preventing and degumming effect and cannot cause secondary pollution to the environment. According to the swelling preventing and degumming agent and the preparation method of the swelling preventing and degumming agent, the phenomenon that rubber, plastics and fiber gaskets of a fuel system are corroded, swelled, stuck, embrittled and softened due to use of methanol gasoline in the prior art is overcome; and the swelling preventing and degumming agent has the advantages that the preparation is simple, the raw materials are easily available, automotive component materials are not required to be transformed and modified, the swelling preventing and degumming effects are good, and the degumming capacity is strong.

Description

technical field [0001] The invention relates to the field of alternative fuels for alcohols, in particular to an anti-swelling degumming agent which is mainly based on 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. Alcohol gasoline, as a clean, cheap and efficient gasoline substitute, has been valued fo...

Problems solved by technology

For example, the announcement number CN101613629A "a kind of methanol gasoline rubber anti-swelling agent" is a kind of invention patent with good effect. Polysuccinimide and fluorocarbon surfactants, etc., but the disadvantage is that it contains unfavorable phosphate esters; the antiseptic ingredients in CN101280229A and CN102161919A have expensive propargyl alcohol, diethyl hydroxysuccinate, cyclic Hexylamine surfactants and environmentally unfavorable creatine hexaphosphate, etc., are limited in use due to the presence of phosphorus, and the addition of dipentene is not conducive to the stability of additives; CN101985569A, CN100564496A and a large number of patent additive reports, Both use benzene compounds that pollute the environment, toluene, and xylene as anti-swelling agents
