The invention discloses a heat-insulating and heat-preserving fluorine-free foam material and a preparation method thereof. The heat-insulation and heat-preservation fluorine-free foam material is prepared by mixing, pouring and curing the following materials A and B in parts by weight: a material: 2-6 parts of kaolin and 120 parts of polyether polyol; b, material B: 0.4-1.2 parts of dibutyltin dilaurate, 1-5 parts of silicone oil, 2-3 parts of triethylene diamine, 2-4 parts of water, 10-16 parts of flame retardant, 12-20 parts of n-hexane and 180 parts of polymethylene polyphenyl polyisocyanate. The thermal insulation and heat preservation fluorine-free foam material has stable chemical property, long service life, no fluorine, environmental protection and environmental protection; has good thermal stability and flame retardant property. |
