Problems solved by technology

The more commonly used packaging materials are metal, paper, expanded polystyrene plastic, polyurethane plastic, etc., but these traditional packaging materials have some shortcomings. For example, although metal packaging materials have high strength, they can protect instruments and equipment. It is free from external damage, but if the instrument and equipment collide with it, it will also cause damage to the instrument and equipment due to its lack of cushioning toughness; although paper packaging, expanded polystyrene plastic packaging and traditional polyurethane plastic packaging have Certain buffer toughness, but low strength, in other words, these packages have better anti-collision effect, but poor anti-extrusion effect. In addition, paper packaging will waste a lot of paper, and the raw material of paper is mainly wood. Therefore, excessive use of paper packaging will naturally lead to a large amount of wood being felled, which is not conducive to environmental protection and water and soil conservation; while polystyrene used in expanded polystyrene plastics often has monomer styrene precipitated during use, which is harmful to the environment. Unfavorable to human health, easy to produce white pollution after discarding

Abstract

The invention discloses a polyurethane package material and a preparation method thereof, and relates to a composite material, a structural material and a preparation method of polyurethane package material. The polyurethane package material is prepared from modified wood flour, polyisocyanate, polyester polyol, polyether polyol, a foam stabilizing agent, an OP-10 emulsifier, water and a catalyst. The polyurethane package material has the characteristics that the polyurethane package material is convenient to produce and manufacture, high in mechanization degree in the production process, small in labor, low in production cost, good in buffer anti-impact property, good in texture, light, convenient to transport, good in waterproof property, free of worm damage, and high in support strength, does not release toxic gas, beneficial for water and soil conservation and environment protection and is environment-friendly as a great amount of trees are not needed to be cut down, and is suitable for being used as package materials of instruments, equipment and the like.

Description

technical field [0001] The invention relates to a polyurethane packaging material and a preparation method thereof, which relate to a composite material, a structural material and a preparation method thereof, and are suitable for making packaging materials for instruments, equipment and the like. Background technique [0002] During the transportation of instruments and equipment, in order to prevent them from being damaged, it is often necessary to use packaging materials with cushioning effects. The more commonly used packaging materials are metal, paper, expanded polystyrene plastic, polyurethane plastic, etc., but these traditional packaging materials have some shortcomings. For example, although metal packaging materials have high strength, they can protect instruments and equipment. It is free from external damage, but if the instrument and equipment collide with it, it will also cause damage to the instrument and equipment due to its lack of cushioning toughness; alt...
