Environment-friendly high-flame-retardancy foam material for packaging and preparation method for environment-friendly high-flame-retardancy foam material

Abstract

The invention discloses an environment-friendly high-flame-retardancy foam material for packaging and a preparation method for the environment-friendly high-flame-retardancy foam material. The environment-friendly high-flame-retardancy foam material is prepared from isocyanate and a mixture in a mass proportion of 1 to 1.75, wherein the mixture is prepared from the following components in parts by mass: 30 to 35 parts of polyester 3628, 65 to 75 parts of polyether 330, 30 to 35 parts of polyester 3360, 25 to 35 parts of polyester 1300, 3.5 to 4 parts of silicone oil, 1.6 to 2.2 parts of a catalyst M62, 2.3 to 2.5 parts of a catalyst M9, 4.8 to 6.5 parts of water and 38 to 40 parts of a flame retardant DMMP. After the material and the method are adopted, the prepared foam material is high in flame retardancy and uninflammable in case of fire, so that fireproof safety and personal safety are ensured; in addition, the packaging material has very low density, so that using requirements of production are met; the raw materials for the foam material are all environment-friendly raw materials, and the raw materials are reasonably matched to prevent release of substances toxic and harmful to a human body, so that environmental protection requirements are met.

Description

technical field [0001] The invention relates to a composite material and a preparation method thereof, in particular to an environment-friendly high flame-retardant foaming material for packaging and a preparation method thereof. Background technique [0002] Packaging materials are commonly used materials in industrial production processes, and their fire safety is very important. In addition to fire safety, existing packaging materials also need to have low density characteristics in order to meet the requirements of use. In order to achieve this Purpose, people are trying various materials as new packaging materials, but they often pursue low density while reducing safety, and often cause fires when encountering failures or accidents, so how to meet the requirements of low density It is an unsolvable technical problem to require flame-retardant properties to ensure safety. In addition, the existing packaging materials are not environmentally friendly and have a great impa...
