Abstract
The present invention relates to an aluminium-plastics composite waterproof material in which bicomponent polyurethane is used as adhesive, aluminium foil as core substrate, the two surfaces of aluminium foil are modified polyvinyl chloride, then dry combinding process is used to make three-layer coiled material or plate material, in which the modified polyvinyl chloride polyvinyl chloride is used as main material and has plasticizer, impact modifier, fire retardant, antistatic agent and antioxidant added. The invented material can be used in high humididy environment for a long period and possesses high impact strength, resistent to acid and alkali corrosion, high adhesion strength, etc.
Description
The present invention relates to a kind of barrier material, be specifically related to a kind of aluminium-plastics composite type moisture-proof layered material.
In waterproof and dampproof material technology field, commonly used is polyvinyl chloride (PVC) waterproof roll now, and its shortcoming is that a waterproof is non-moistureproof.Another kind of commonly used moisture-proof packaging material is an aluminium foil, and aluminium foil is to lead material into as thin as a wafer with high purity metal lead through calendering back repeatedly, and generally duralumin paper tinsel thickness is 20～25 μ m, and soft aluminum foil thickness is 2～9 μ m.That aluminium foil itself has is light tight, wet thoroughly, the advantage of gas not, but its apparent mechanical strength is not high, easily tears up to fracture.Above-mentioned two kinds of materials are compound, be a kind of aluminium plastic composite material.Compoundly mainly comprise one pack system pressure sensitive adhesive and bi-component polyurethane ester gum with adhesive, the 46th～47 page discloses about the composite modified technology contents with adhesive of plastics in Wang Wenguang chief editor " modifying plastics practical technique " book that in March, 2000, China Light Industry Press published, and discloses also the 51st～58 page of this book that relevant plastics are done, the compound process of wet type.In sum, in existing aluminium-plastics composite type moisture-proof layered material, exist some deficiency, the first, composite material surface is reflective, and this is unfavorable for the safe storage of some combustible and explosive articles; The second, in the high wet environment of relative humidity 〉=70%, easily go mouldy; The 3rd, current material intensity is low, and impact resistance is poor.Especially the barrier material that is suitable in the ammunition depot hole on the island is not seen open report as yet.
