The formula of the anti-freezing gas leakage detection aerosol comprises the following components in parts by weight: 1-8 parts of a foaming agent, 1-6 parts of a foam stabilizer, 0.1-2 parts of a metal corrosion inhibitor, 25-50 parts of an anti-freezing agent, 0.1-0.8 parts of a thickening agent, 1-10 parts of a propellant and 60-90 parts of deionized water. According to the anti-freezing type gas leakage detection aerosol, the anti-freezing effect is improved, meanwhile the defoaming effect brought by an anti-freezing agent is eliminated, the foaming and foam stabilizing performances of the gas leak detection agent can be improved under the condition that the anti-freezing performance is not affected, the foam stabilizing performance can reach 8 hours or above, the anti-freezing gas leakage detection aerosol canbe used at the low temperature of -35 DEG C, and it is guaranteed that the leakage condition of a pipeline is rapidly, accurately and effectively detected.

Description

Technical field [0001] The invention relates to the technical field of gas leak detection agents, in particular to an antifreeze type gas leak detection aerosol and a preparation method thereof. Background technique [0002] In daily life and industrial production, there is a great danger of gas leakage. For example, the leakage of natural gas for daily use can cause people to suffocate. Because the main component of natural gas is alkanes, it is easy to explode in case of open fire, and it is dangerous. , If there is a gas leak in industrial pipelines, valves, etc., it may lead to unstable production at light, and safety accidents at heavy. Therefore, the detection of gas leaks becomes a very important safety item. Gas leak detectors are mainly used to detect leaks in various gas transportation pipelines. For example, in the prior art, soapy water is used for leak detection of gas pipelines, the oil stains on the detected parts are wiped clean, soapy liquid is sprayed on the pi...

AI Technical Summary

Problems solved by technology

However, the existing gas leak detection agents have the following problems: (1) The existing gas leak detection agents have not been deeply researched and developed for the antifreeze performance. The main functional requirements such as foaming and foam stabilization, and the antifreeze performance of the added antifreeze cannot meet the requirements of the use environment, so it is impossible to quickly detect and locate the tiny holes of gas leakage in winter or in low temperature and harsh environments; (2) Most of the existing gas leak detection agents contain flammable gas components as propellants (such as petroleum gas, dimethyl ether), and are prone to explosion safety accidents when exposed to open flames or heat during the leak detection process; ( 3) The existing gas leak detection agent contains sodium ions, and sodium ions will corrode the aerosol can and leak through the can, thus affecting the safety and stability of the aerosol. It will cause a certain degree of corrosion to the detected pipeline, and affect its safety and reduce the service life of the pipeline; (4) The waiting time for the existing gas leak detection agent to detect the leak is too long, and the leak point cannot be detected quickly. It is cumbersome and needs to be repeatedly inspected and observed carefully to confirm the leak point
