Problems solved by technology

The TV casings in the prior art mostly use plastic products, but plastics usually have poor flame retardancy, and are prone to 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 substances by the human body will cause greater harm to health.

Abstract

The invention discloses an environmental-protection and high-flame retardation television shell composite material and a preparation method thereof. The composite material comprises polyether polyol 1, polyether polyol 2, polyester polyol, a plasticizer, a catalyst, tris(1-chloro-2-propyl)phosphate, water and isocyanate. The composite material has high flame retardation property and is uninflammable when meeting fire, so internal members of a television 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 TV shell composite material and a preparation method thereof. Background technique [0002] The TV shell can protect the core and picture tube and other components in the TV. Since there is current passing through the TV, it will absorb dust, so the shell can play a certain role in isolating dust; the TV shell is generally made of insulating materials. It can protect people from being injured by high-voltage electricity in the TV. Most of the TV casings in the prior art use plastic products, but plastics usually have poor flame retardancy, and are easy to cause fires when encountering accidents, thereby causing 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 volatili...
