Abstract

The invention provides a high flame-retardant polyurethane composition and a preparation method thereof. The high flame-retardant polyurethane composition consists of an A component and a B component, wherein the A component consists of polyether polyol, flame-retardant polyether polyol, a cross-linking agent, a foam stabilizer, water, a physical foaming agent and a catalyst; and the B component consists of the polyether polyol, a flame retardant, polymeric MDI and a toluene diisocyanate prepolymer. When in use, the A component and the B component are evenly mixed according to the weight ratio that A: B is equal to 100: 50-60 and injected into a mold at the mold temperature of 45-65 DEG C, mold-opening is carried out after 5-10 minutes, and placing is carried out for 24 hours at the normal temperature. The high flame-retardant polyurethane composition can achieve the higher flame retardance without additionally adding the flame retardant, the oxygen index is not less than 32, and the high flame-retardant polyurethane composition has the advantages of good fluidity, high storage stability and the like, thereby being very convenient to use and store by a foaming manufacturer.

Description

technical field [0001] The invention belongs to the field of polyurethane compositions, in particular to a highly flame-retardant polyurethane composition and a preparation method thereof. Background technique [0002] Polyurethane high-resilience molded soft foam is mainly used in the fields of automobiles, furniture cushions, toys, etc., and has a certain flame-retardant effect. , Car seat foam manufacturers all over the world have replaced the conventional materials for many years with retardant materials. [0003] In order to improve the flame retardancy of the combined material, flame retardants are generally added to the white material components of the original system, such as solid melamine and liquid TCPP. This method is simple and easy to implement, but what follows is that the storage stability of the white material component is greatly reduced, and even precipitation occurs within a week, and what is more, the reaction speed is greatly reduced, which seriously a...
