Abstract

The invention discloses an efficient flame-retardant environment-friendly polyurethane flexible foam plastic for an interior part of a passenger car and a preparation method of the efficient flame-retardant environment-friendly polyurethane flexible foam plastic. The efficient flame-retardant environment-friendly polyurethane flexible foam plastic takes polyester polyol and structural type flame-retardant polyether polyol as the main raw materials, and the main raw materials are mixed, foamed and polymerized with an isocyanate component under the actions of a reaction type or low-odor catalyst, a physical and / or chemical foaming agent and a foam stabilizer and / or a fire retardant to generate the polyurethane flexible foam plastic. The flame retardance and the environmentally friendliness of the product both meet the application requirements of a composite material, and the polyurethane flexible foam plastic is convenient to prepare.

Description

technical field [0001] The invention relates to a flame-retardant polyurethane flexible foam plastic, in particular to a flame-retardant polyurethane flexible foam for passenger car interior decoration and a preparation method thereof. Background technique [0002] Polyurethane flexible foam is referred to as soft foam, commonly known as sponge, which refers to soft polyurethane foam with certain elasticity. It is mainly used for furniture cushions, vehicle seat cushions and various soft cushion laminated composite materials. Ordinary sponge is a flammable material, but it also has flame retardant requirements in some fields, such as baby carriages, car interiors, etc. [0003] In recent years, automobile combustion safety accidents have occurred frequently, and the combustion test standard for automobile interior materials is one of the important factors to ensure automobile safety. All countries have clear regulations on the flammability of automotive interior fabrics. my...
