Technical field

The invention relates to the technical field of rubber and plastic products, in particular to an improved protective agent for high temperature resistant test instruments.

Background technique

With the widespread use of metal products in modern industry and life, the corresponding metal corrosion is becoming more and more serious. It is estimated that the direct economic loss caused by corrosion accounts for about 3%-4% of the GDP. Therefore, various anti-corrosion Technology has been widely used in chemical, petroleum, electric power, machinery, metal processing, transportation, nuclear energy and aerospace fields. At present, the main anti-corrosion measures are the selection of corrosion-resistant materials, cathodic protection, anode protection, media treatment, corrosion inhibitors, coating protection, oxidation treatment, etc. Among them, coating protection is the most widely used and effective measure.

Traditional metal surface protective agents dissolve protective substances capable of forming SAMs in organic solvents (such as halogenated alkanes, alcohols, ketones, etc.), but these organic solvents are generally volatile organic compounds, which not only pollute the environment, but also waste a lot of resources With the global climate change and the increasing tension of resources and energy, countries around the world have successively formulated strict environmental protection laws and policies to encourage and promote the use of new products that are environmentally friendly, energy-saving and energy-saving.
