Problems solved by technology

[0002] The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeated carbamate groups on the main chain. Polyurethane materials are very versatile and can replace rubber, plastic, nylon, etc., and are used in airports, hotels, Building materials, automobile factories, coal mine factories, cement factories, high-end apartments, villas, landscaping, colored stone art, parks, etc., but the foam insulation board made of traditional polyurethane materials has a low fire rating or even no fire protection, and is extremely vulnerable to ultraviolet rays. It is easy to age, so that the articles produced by polyurethane cannot adapt to various use occasions. Therefore, the present invention proposes an improved polyurethane foam insulation board and its preparation method
