Problems solved by technology

However, ordinary anti-corrosion coatings have a short aging life and poor tolerance to harsh environments. It is difficult to provide reliable protection for structures for 30, 50 or even 100 years.
Ordinary anti-corrosion coatings need to be re-coated 3-5 years after coating, resulting in a huge waste of manpower, material resources, and financial resources. However, the service life of my country's heavy-duty anti-corrosion coatings is only 15-20 years after one coating, which is far away. Unable to meet the protection requirements of important infrastructure for more than 100 years

Abstract

The invention discloses an anti-corrosion anti-aging surface protection material and a preparation method thereof. The surface protection material is prepared from first mixture and second mixture in the normal temperature, and the weight ratio between the first mixture and the second mixture is (3 to 5):1; the first mixture is prepared from the following raw materials in parts by weight: 40 to 60 parts of emulsified asphalt, 30 to 50 parts of epoxy resin, 6 to 10 parts of glycerol, 4 to 6 parts of epoxy resin reactive diluents, 2 to 4 parts of emulsifier and 7 to 9 parts of methyltris (methylethylketoximino) silane and polytetramethylene ether glycol, wherein the weight part ratio between the methyltris (methylethylketoximino) silane and the polytetramethylene ether glycol is (6 to 8):1; the second mixture is prepared from the following raw materials in parts by weight: 35 to 45 parts of waterborne curing agent, 15 to 25 parts of toluene diisocynate and 4 to 8 parts of ethylene glycol. The surface protection material has light aging resistance and acid-base corrosion resistance, is suitable for any severe service environment and can effectively protect infrastructure and prolong the service life of the infrastructure when being sprayed on the surface of the infrastructure.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an anti-corrosion and anti-aging surface protection material and a preparation method thereof. Background technique [0002] The service environment of infrastructure is usually harsh. In order to improve the service life of infrastructure, effective protection of key parts is very important. At present, anti-corrosion coatings are usually applied on the surface of key parts to isolate water, air, corrosive media and other substances, thereby producing a protective effect. However, ordinary anti-corrosion coatings have a short aging life and poor tolerance to harsh environments. It is difficult to provide reliable protection for structures for 30, 50 or even 100 years. Ordinary anti-corrosion coatings need to be re-coated 3-5 years after coating, resulting in a huge waste of manpower, material resources, and financial resources. However, the service life of my country's heav...
