Waterproof, corrosion-resistant and fire-retardant PU (polyurethane) coating and preparation method thereof

Abstract

The invention discloses a waterproof, corrosion-resistant and fire-retardant PU (polyurethane) coating. The PU coating comprises a component A and a component B which are mixed in the same proportion, wherein the component A comprises components as follows: diisocyanate, polypropylene carbonate diol, a small-molecular chain extender, a catalyst, a catalyst capture agent, an organic solvent, a flame retardant and a foaming agent; the component B comprises components as follows: a curing agent and a coupling agent. The invention further designs a preparation method of the waterproof, corrosion-resistant and fire-retardant PU coating. The preparation method of the coating is simple, easy to operate and low in cost, and the prepared coating is good in corrosion resistance, excellent in electrical performance, good in decoration and protection performance and good in temperature resistance.

Description

technical field [0001] The invention relates to a fireproof coating and a preparation method thereof, in particular to a water-resistant and corrosion-resistant polyurethane fireproof coating and a preparation method thereof, belonging to the field of fireproof coating materials. Background technique [0002] In the early 1990s, the real estate industry and the furniture industry developed rapidly after the reform and opening up, and more and more wooden materials entered people's lives. However, due to bad living habits, such as children playing with fire, frequent fires in the home Occurs, simultaneously because the quantity of high-rise building occupant is more and reasons such as its height, once break out of fire, especially when disaster situation is serious, be difficult to fight, cause the lives and properties of broad masses of people to be seriously threatened. Therefore, we need to take a lot of safety measures to improve the fire performance of buildings, househ...
