Problems solved by technology

Although the multi-component polyurethane waterproof coating currently used can form a good waterproof layer, its low-temperature flexibility and other properties are poor, and it cannot meet the requirements for sealing and anti-deformation of the bottom plate of the storage tank
In addition, the contact parts between the bottom edge plate and concrete of various large storage tanks are often separated from the concrete foundation due to the deformation of the bottom of the tank, and water and corrosive media invade the bottom of the tank and cause corrosion of the bottom of the tank.

Abstract

The invention discloses CTPU high-performance storage tank bottom special sealant middle-layer paint and a preparation method thereof. The CTPU high-performance storage tank bottom special sealant middle-layer paint is a double-component polyurethane elastic paint, comprising a component A and a component B, wherein the component A comprises toluene diisocyanate, methyl diphenylene diisocyanate, TBIOL2000 polyether, TMN3000 polyether and TBIOL1000 polyether. The component B comprises an amine chain extender, TMN3000 polyether, TBIOL2000 polyether, TBIOL1000 polyether, a plasticizer 100, a wetting agent T80, a light reflective agent, an antioxidant 1010, pigment, filler and assistant agents comprising a thinner, an accelerant, a defoaming agent and the like. The CTPU high-performance storage tank bottom special sealant middle-layer paint has simple construction, and construction can be carried out only by mixing the component A and the component B uniformly according to a proportion under room temperature. The CTPU high-performance storage tank bottom special sealant middle-layer paint can be used for sealing the bottoms of various storage tanks and the gaps of concrete, and can also be used for sealing various bridges, docks, metal parts, foundation bolts and the like.

Description

technical field [0001] The invention belongs to the technical field of chemical building materials, specifically building waterproof coatings and a preparation method thereof, and more specifically a CTPU high-performance storage tank bottom special sealant middle layer coating and a preparation method thereof. Background technique [0002] At present, China's economy is developing at a high speed, and its demand for oil is also increasing rapidly. With the emergence of a large number of oil storage depots, the leakage of storage tanks (especially the bottom plate) due to corrosion will become a very serious problem. The leakage of the storage tank is mainly due to the contact between the outside of the bottom plate and the soil through the tank foundation, and the O in the soil 2 、H 2 O, salt and sulfate-reducing bacteria constitute the external corrosion environment of the bottom plate of the tank; the oil medium is stored inside the tank, and the H in the oil 2 O, S 2...
