Problems solved by technology

[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 At the same time, due to the large number of people living in high-rise buildings and their heights, once a fire breaks out, it is difficult to extinguish it, especially when the disaster is serious, resulting in a serious threat to the lives and property of the broad masses of people.

Abstract

The invention discloses a water-proof two-component polyurethane coating. The polyurethane coating comprises a component A and a component B mixed in the equal ratio, wherein the component A comprises components as follows: diisocyanate, poly propylene carbonate diol, a micromolecule chain extender, a catalyst, a catalyst capturing 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 water-proof two-component polyurethane coating. The preparation method of the coating is simple and easy to operate, the cost is low, 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 two-component water-resistant polyurethane coating and a preparation method thereof, belonging to the field of fireproof 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, household combustibles, etc., to e...
