Environmental-protection and high-flame retardation refrigerator shell composite material and preparation method thereof

Abstract

The invention discloses an environmental-protection and high-flame retardation refrigerator shell composite material and a preparation method thereof. The composite material comprises polyether polyol 1, polyether polyol 2, polyether polyol 3, polyurethane silicone oil, a foaming agent, a catalyst, tris(1-chloro-2-propyl)phosphate, water, isocyanate A and isocyanate B. The composite material has high flame retardation property and is uninflammable when meeting fire, so internal members of the refrigerator are protected, and the safety of properties is guaranteed. All raw materials used for preparing the above composite material in the invention are environmentally friendly raw materials, so the composite material does not release substances toxic or harmful to human bodies, and is healthy and harmless to the human bodies.

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 refrigerator casing composite material and a preparation method thereof. Background technique [0002] The outer casing of the refrigerator can protect the internal components of the refrigerator. Because there is an electric current passing through the refrigerator, it will absorb dust, so the outer casing can play a certain role in isolating dust; some outer casings of refrigerators in the prior art are made of plastic products Yes, but plastics usually have poor flame retardancy, which can easily cause fires in the event of accidents, resulting in serious loss of life and property. Moreover, the source of raw materials of some plastic products in the prior art is not environmentally friendly, and some toxic and harmful substances are often volatilized, and the long-term inhalation of these toxic and harmful su...
