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 cushioning toughness, but lo

Abstract

The invention discloses a nano-modified polyurethane packaging material and a preparation method thereof, and relates to a composite material, a structural material and a preparation method of the composite material. The nano-modified polyurethane packaging material is prepared by the following steps: preparing a white material composition from modified graphene, polyether polyol, polyester polyol, a foaming stabilizer, glycerinum, water, cyclopentane, triethylene diamine (33% water solution) and stannous octoate; mixing with polyisocyanates; and heating and foaming, so as to prepare the nano-modified polyurethane packaging material. The nano-modified polyurethane packaging material is convenient to produce, manufacture and transport, low in production cost, good in buffer shock resistance, high in support strength, good in texture, light in weight, good in waterproofness, free of damage of worms, not easy to deform, free of a poisonous gas styrene, friendly to environment, and antistatic, and is capable of resisting interferences such as electromagnetic valves and radio frequency; and the method is suitable for fabrication of the packaging materials of instruments, equipment, electronic products, electric tools and the like.

Description

technical field [0001] The invention relates to a nano-modified 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, electronic products, electric tools and the like. Background technique [0002] In order to prevent damage to instruments, equipment, electronic products, and electric tools during transportation, it is often necessary to use packaging materials that have sufficient strength and rigidity and also have a cushioning effect. 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...
