2With one or more inorganic nano-particles in the talcum powder, diameter is 10-80nm, the best is 20-50nm, its in hot melt adhesive with the composite nanometer hot melt adhesive that obtains of polymer resin components (A, B, C component), can increase mechanics, the thermal property of hot melt adhesive, absorption and durable adhesion power, consumption is the 0.05-3% of fluoropolymer resin gross weight in the hot melt adhesive.
In addition detailed again to each component of the present invention below explanation: component A adhering resin masterbatch of the present invention is implemented by the twin screw reaction extrusion process, and polyethylene is in the matrix resin: melting index is 0.1-30g/10min, density＞0.945g/cm
3High density polyethylene(HDPE) (HDPE), melting index is 0.1-20g/10min, density＞0.92-0.93g/cm
3Linear low density polyethylene (LLDPE).For regulating consistency, melting index and the snappiness between blend, it can add weight ratio 40% ethylene-vinyl acetate blending resin at the most, wherein vinyl acetate between to for plastic (VA) content is 15%-43%, melting index＞20g/10min, 500g/10min at the most.HDPE should account for the 90-50wt% of constituent in the adhering resin material generally speaking, be preferably 85-60wt%, as＜then bonding force is poor for 50wt%, if＞95wt% then makes adhering resin masterbatch elongation at break reduce, performance becomes fragile, and is not suitable for doing crooked arbitrarily plastic-aluminum pipe adhesive linkage and uses.The initiator that adopts is the most frequently used benzoyl peroxide (BPO), peroxide fat diisopropylbenzene(DIPB) (DCP) etc., unsaturated polar monomer has maleic anhydride (MAH), vinylformic acid (AA), adds weight ratio and be the adhering resin masterbatch that 0.05～0.2% initiator and unsaturated polar monomer grafting obtain having bonding force in this HDPE, LLDPE and EVA are the mixture of matrix resin.Under 160-250 ℃ temperature, adopt twin screw commonly used to extrude, unsaturated polar monomer accounts for the 0.01-10wt% of whole proportion of composing, ideal consists of 0.01-4wt%, if＜0.01wt% then bonding force reduces, the unreacted unsaturated monomer that＞4wt% is then unnecessary can produce variable color, gel, bubble, irritating smell influences final product quality and permanent stability.In hot melt adhesive was formed, adhering resin masterbatch ratio was the 10-80% resin, and＜10wt% does not then have bonding force, and＞80wt% then cost rises and irritating smell is arranged, and the best is 20%-50wt%.
The tackifying resin that the present invention adopts is cis-1,4-polybutadiene rubber, SBS, paracril, petroleum resin, polyethylene wax etc., by with the composite hot melt adhesive that obtains of the blend of adhering resin masterbatch and polyethylene hydrocarbon, strengthen the initial bonding strength of hot melt adhesive product and the seepage force on aluminium surface, make hot melt adhesive can evenly be bonded in the aluminium strip surface, form the bonding interface cohesive failure.3-20wt% in the ratio of tackifying resin in hot melt adhesive, as＞then softening temperature reduction of 20wt%, non-refractory, and mechanical properties decrease, with the consistency variation of PE resin,＜3wt% does not then have the tackify effect, and optimum proportion is 5-10wt%.
The inorganic nano-particle that the present invention adopts is CaCO
3, TiO
2, SiO
