Environmental-protection and high-flame retardation storage cabinet sheet composite material and preparation method thereof

Abstract

The invention discloses an environmental-protection and high-flame retardation storage cabinet sheet composite material and a preparation method thereof. The composite material comprises polyether polyol, polyester polyol, plant oil polyether polyol, triethanolamine, polyurethane silicone oil, 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 the safety of a storage cabinet and the safety of people's properties are guaranteed. All raw materials used for preparing the 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 locker plate composite material and a preparation method thereof. Background technique [0002] Most of the lockers in the prior art are made of wood, and the wood itself is easy to burn, so it is easy to burn and catch fire when a fire occurs, thereby aggravating the harm of fire. Simultaneously due to the burning of the coating paint etc. on the wood surface, more poisonous and harmful gases will be released, which will often cause greater harm to people when inhaled by the human body when a fire occurs. In addition, wooden lockers also have the following defects, such as easy deformation, which is also determined by the characteristics of wood; at the same time, during the manufacturing process of wooden lockers, more glue is often used for bonding and pressing between wooden boards. Glue contains a large amo...

Problems solved by technology

[0002] At present, most of the lockers in the prior art are made of wood, and the wood itself is easy to burn, so that it is easy to burn when a fire occurs, thereby aggravating the harm of fire.

At the same time, due to the burning of paint and paint on the surface of wood, more toxic and harmful gases will be released, which will often cause greater harm to people if they are inhaled by the human body when a fire occurs.

In addition, wooden lockers also have the following defects, such as easy deformation, which is also determined by the characteristics of wood; at the same time, during the manufacturing process of wooden lockers, more glue is often used for bonding and pressing between wooden boards. Glue contains a large amount of formaldehyde, and formaldehyde needs a release cycle of several years to release, so it is not conducive to the health of the occupants; in addition, if the wooden lockers are used or kept improperly, they are also susceptible to moisture, which can easily lead to damage to the lockers. Mildew and corrosion, thus affecting the service life of the locker
