Anti-static flame-retardant ultraviolet-resistant polyurethane packaging material and preparation method thereof

Abstract

The invention discloses an anti-static flame-retardant ultraviolet-resistant polyurethane packaging material. The anti-static flame-retardant ultraviolet-resistant polyurethane packaging material is prepared from the following materials in parts by weight: 100-120 parts of isocyanate, 90 parts of polyether polyol, 10-15 parts of polyester polyol, 1.1-2 parts of foam stabilizer, 0.7-0.9 part of silicon oil, 1-2.5 parts of water, 4-8 parts of cyclopentane, 2-6 parts of ultraviolet absorbent, 0.5-2 parts of antioxidant, 1-5 parts of conductive fiber, 2-6 parts of nitrogen-containing flame retardant, 0.08-0.15 part of triethylene diamine (33% aqueous solution) and 0.1-0.4 part of stannous octoate. The anti-static flame-retardant ultraviolet-resistant polyurethane packaging material disclosed by the invention has the advantages that the ultraviolet absorbent UVP-327 is added, and can absorb ultraviolet rays strongly with the absorption wavelength being 270-380, the chemical stability is good, the volatility is extremely low, the thermal-sublimation resistance, the washing resistance, the gas-fading resistance and the mechanical-performance retentivity are excellent, meanwhile the synergistic effect is obvious when the anti-static flame-retardant ultraviolet-resistant polyurethane packaging material and the antioxidant are used together, and the thermal-oxidation stability of the packaging material can be obviously improved; the added amount of the used carbon fiber is less, and permanent anti-static performance is achieved; and by addition of the nitrogen-containing flame retardant, the anti-static flame-retardant ultraviolet-resistant polyurethane packaging material has good flame-retardant performance.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to an antistatic, flame-resistant, and ultraviolet-resistant polyurethane packaging material and a manufacturing method thereof. 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 collide with it, it will also cause damage to the instrument and equipment due to its lack of cushioning toughness; alth...

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 low strength and poor rigidity, in other words, these packages have better anti-collision effects, but poor anti-extrusion effects. In addition, paper packaging will waste a lot of paper, and the raw materials for paper It is mainly wood, so excessive use of paper packaging will naturally lead to a large amount of wood being cut down, which is not conducive to environmental protection and water and soil conservation; and polystyrene used in expanded polystyrene plastics often has monomer benzene during use. Ethylene is precipitated, which is not good for human health, and it is easy to produce white pollution after being discarded

[0003] However, polyurethane packaging materials still have the following problems: First, the oxidation reaction caused by long-term exposure to ultraviolet light makes the service life of the film short, the shelf life of the items in the package is short, and even deteriorates prematurely; Static electricity will be generated in the medium, which limits its application range; the third is that it does not have flame retardancy
