Description
Technical field
The present invention relates to wrapping material field, specifically a kind of uvioresistant urethane wrapping material and preparation method thereof.
Background technology
Instrument, equipment, electronic product, power tool etc., in transportation, for preventing it to be damaged, often needing use both to have sufficiently high intensity and rigidity, also having the wrapping material of shock absorption simultaneously.Comparatively conventional wrapping material have metal, paper, foamed poly styrene plastic, urethane plastic etc., but these traditional wrapping material also exist or this or that shortcoming, such as, although metal packing material has high strength, plant and instrument can be protected from the destruction of external force, if but instrument, equipment self bumps against with it, because it lacks buffering toughness, can damage instrument, equipment equally; Although papery packaging, foamed poly styrene plastic packaging and conventional urethane plastic wrapping have certain buffering toughness, but intensity is lower, rigidity is not good enough, in other words, these packaging anti-collision effect are better, but anti-extrusion less effective, in addition, papery packaging is by paper a large amount of for waste, and the making raw material mainly timber of paper, so excessive use papery packaging nature causes a large amount of timber to be cut down, and is unfavorable for environment protection and soil conservation; And the polystyrene used in foamed poly styrene plastic in use often has monomer styrene precipitation, unfavorable to HUMAN HEALTH, abandon rear easy generation white pollution.
But the oxidizing reaction caused presented a note to by urethane wrapping material at ultraviolet, make article shelf lives in short, packaging in film work-ing life short, occur rotten even too early.
