Mask environment-friendly flame retardant foaming material and preparation method thereof

Abstract

The invention discloses a mask environment-friendly flame retardant foaming material and a preparation method thereof. The mask environment-friendly flame retardant foaming material is prepared from the following components including acetonitrile polyester and a composition material with the mass proportion of 1 to 1.4; the composition material is prepared from the following components in parts by mass: 30-40 parts of polyester 3628, 40-50 parts of polyether 330, 25-28 parts of polyether 403, 200-300 parts of glass fiber, 25-35 parts of polyether 135, 3-3.5 parts of silicone oil, 1.5-2.5 parts of catalyst A33, 1.2-2.2 parts of powerful catalyst HP-50, 4.8 parts of water and 30-38 parts of flame retardant DMMP, wherein the silicone oil is silicone oil AK-8803. The preparation method comprises the following steps: adding the components of the composition material in a reaction kettle to carry out mixing reaction with the stirring speed being 130-150r / min and the stirring time being 4-5h to obtain the composition material, then uniformly mixing the acetonitrile polyester and the composition material according to the mass ratio of 1 to 1.4 to prepare the mask environment-friendly flame retardant foaming material. By adopting the materials and the method, the prepared mask environment-friendly flame retardant foaming material is high in high temperature resistance performance, flame retardant performance and strength, and is environmentally friendly.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant foaming material for a mask and a preparation method thereof, belonging to the field of automobiles. Background technique [0002] At present, with the development of the automobile industry and the enhancement of people's awareness of safety and environmental protection, people's requirements for auto parts have also increased significantly. , High environmental protection characteristics, the characteristics of traditional masks usually can not achieve a more ideal effect, in the event of an emergency, often due to poor flame retardancy and resulting in a short escape time, there is a great safety hazard. Therefore, exploring high-strength, high flame-retardant, high-environmental protection foaming materials is the goal that this field has been pursuing. Contents of the invention [0003] The object of the present invention is to overcome the defects in the prior art, and provide an...
