Problems solved by technology

Coating technology has high requirements on the surface state of the substrate, so it is difficult to repair and maintain in the later stage; the FRP coating layer is prone to pores, and its edge sealing is poor due to its strong rigidity. Serious; PTC petrolatum coating technology uses many types of materials and cumbersome procedures, and the protective cover needs to be fastened repeatedly in a short period of time, which is not convenient for construction and has a long construction period; HDPE petrolatum coating technology is not resistant to scratches, poor memory, The anti-aging performance is poor, the armor is easy to fall off and damaged, and the use is limited; corrosion-resistant stainless steel, titanium steel and other technologies are not conducive to large-scale application due to the high price of materials

Abstract

The invention discloses a high-memory microfiber armor coating corrosion preventing method. The method is characterized by including following steps: S1, designing a microfiber armor: designing a microfiber armor structure and a processing drawing according to a design drawing or on-site measurement data of a protected structure, wherein the microfiber armor structure comprises a high-strength microfiber protection outer layer, a high-memory fiber layer, a buffer protection layer, an oil fixing layer and a sacrificial anode layer sequentially from outside to inside, and the oil fixing layer is coated and saturated with corrosion-preventing ore grease; S2, processing the microfiber armor: making the microfiber armor according to the microfiber armor structure and the processing drawing; S3, mounting the microfiber armor: coating a protected position with the microfiber armor, and locking the microfiber armor to complete construction. The microfiber armor has the advantages of capability of being firmly coated on the surface of a protected body, high memory, high strength, impact resistance, puncture resistance, weatherability, resistance to acid and alkali and high corrosion resistance and has wide production and application value in heavy corrosion preventing protection armors like metal, concrete and wooden structure.

Description

Technical field [0001] The invention relates to the field of anti-corrosion of wooden, concrete, and metal structures, in particular to a high-memory microfiber armor coating anti-corrosion method. Background technique [0002] In the prior art, at present, heavy-duty anti-corrosion mainly adopts heavy-duty anti-corrosion coating technology, as well as coating technologies such as FRP, PTC, HDPE, and corrosion-resistant steel, which have a long-term protective effect on structures. However, there are deficiencies in existing heavy-duty anti-corrosion technologies for local key areas and key parts such as structures in the splash zone and tidal range zone of the ocean, and steel structure nodes. Coating technology requires high substrate surface conditions, so it is difficult to repair and maintain later; FRP coating is prone to pores, and due to its strong rigidity, the edge sealing is poor. Once the corrosive medium enters the interior, it will form hidden corrosion, which makes...
