specific Embodiment approach

[0020] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A two-component polyurethane waterproof coating for marine use is formed by mixing material A and material B, wherein material A is a prepolymer synthesized from polyhydric alcohol and excess polyisocyanate, and material B is composed of a curing agent, an expansion Chain agent, additives and fillers. Wherein the raw material weight component of material A is 50% polyol and 50% excess polyisocyanate, wherein polyol is made up of 40% polyglycerol ether, 40% polypropylene glycol and 20% glyceride, polyisocyanate is 50% 2, A mixture of 4-toluene diisocyanate and 50% 2,6-toluene diisocyanate. The raw material weight component of material B is 50% curing agent, 20% chain extender, 20% auxiliary agent and 10% filler. The curing agent is made of 60% 3,3'-dichloro-4,4'-diamino It is prepared from diphenylmethane and 40% polypropylene glycol. The chain extender is diethyltoluene methylamine. The additives are 30% defoamer, 20% a...

Abstract

The invention discloses a double-component polyurethane water-proof paint for a ship. The double-component polyurethane water-proof paint is formed by mixing a material A and a material B, wherein the material A is prepolymer which is synthesized from polyalcohol and excess polyisocyanate; and the material B consists of the following materials in percentage by weight: 50 percent of curing agent, 20 percent of chain extender, 20 percent of auxiliary agent and 10 percent of filler. The double-component polyurethane water-proof paint has the advantages of high tensile strength, high adaptability to deformation of a base layer, superior low-temperature performance and the like.

Description

technical field [0001] The invention belongs to the field of ship construction, in particular to a waterproof coating for ships. Background technique [0002] At present, in ship construction, the waterproof treatment of the living area of ​​the ship's cabin is a very important link. Due to the structure and functional characteristics of the living area of ​​the ship's cabin, the existing waterproof coating has poor adaptability to the deformation of the base layer during construction. The low-temperature performance is weak, the tensile strength is small, etc. In addition, the waterproof effect of the existing waterproof coating is not ideal, and seams are easily left, which is very inconvenient to repair. Contents of the invention [0003] The object of the present invention is to provide a two-component polyurethane waterproof coating for ships that not only has high tensile strength, strong adaptability to base deformation, excellent low temperature performance, strong...
