Environment-friendly and flame-retardant polyurethane foaming material for face mask and preparation method

Abstract

The invention discloses an environment-friendly and flame-retardant polyurethane foaming material for a face mask and a preparation method. The environment-friendly and flame-retardant polyurethane foaming material for the face mask is prepared from the following components in parts by mass: acetonitrile polyester and a composite material in the ratio of 1 to 1.75, wherein the composite material is prepared from the following components in parts by mass: 25 to 35 parts of polyester 3350, 20 to 30 parts of polyether 4110, 200 to 280 parts of reinforced glass fiber, 2.8 to 4.2 parts of silicone oil, 8 to 10 parts of triethanolamine, 1.5 to 2.2 parts of catalyst A33, 1.5 to 2 parts of catalyst HP-53, 3.5 to 4.2 parts of water and 42 to 48 parts of flame retardant DMMP (Dimethyl Methyl Phosphonate), wherein the silicone oil is silicone oil AK-8801. The preparation method comprises the following steps: adding the components of the composite material into a reaction still for carrying out hybrid reaction, and stirring at the stirring speed of 130 to 150r / min for 4 to 5 hours to obtain the composite material; then uniformly mixing the acetonitrile polyester and the composite material according to the ratio of 1 to 1.75 to obtain the environment-friendly and flame-retardant polyurethane foaming material for the face mask. By adopting the material and the method, the prepared environment-friendly and flame-retardant polyurethane foaming material for the face mask has the advantages of flame retardance, high temperature resistance, high flame-retardant property, high strength and environment friendliness.

Description
