Description
Technical field
The present invention relates to heat-resistant clothing hot melt adhesive and preparation method thereof, particularly high-grade clothing elevated temperature heat melten gel and preparation method.
Background technology
PET, PA, TPU or EVA based melt adhesive have advantages such as bonding strength height and medium-resistance be good, timber, metal, pottery, fabric, paper and other polyolefine materials are had good adhesiveproperties, yet their thermostability makes its application be subjected to certain restriction.At high temperature, PET, PA, TPU or EVA are the softening easily even fusing of the hot melt adhesive of base material, lose its bonding effect.Therefore, these undressed hot melt adhesives are unfavorable at high temperature using.CN 101070455A discloses a kind of method of coming curing cross-linked EVA by the method for adding the oxidation diisopropylbenzene(DIPB), has improved the temperature classification of EVA; CN 1800287A discloses a kind of modified EVA hot-melt adhesive, adopts the crosslinked EVA of silane coupling agent to improve the thermal stability of EVA hot melt adhesive.For PET, PA, TPU and EVA, though the patent and the report of relevant crosslinking technological are arranged, crosslinking technological is still immature, has hindered its application in the high temperature field.And a large amount of crosslinked its flexibilities of having destroyed, particularly reduced the comfortableness of clothes with hot melt adhesive.
Polyethylene (PE) is a most important derived product in the macromolecular material, accounts for about 70% of world's superpolymer consumption.Chemical stability, nonpoisonous and tasteless, the low price of anti-organic burn into good mechanical property performance, excellence.Yet, the polyethylene non-refractory, the maximum operation (service) temperature of new LDPE (film grade) is 60 ℃, the high density polyethylene(HDPE) maximum operation (service) temperature can only reach about 70 ℃.Shortcomings such as CN 200510116675 has introduced the silicone-modified unformed polyolefins hot melt adhesive of a kind of process, still has processing and stores difficulty, and curing speed is slower, and relative initial bonding strength is lower.CN00109087.9 to polyethylene carry out with radiation after carry out fusion-grafting, grafting gets polyethylene and adhesivepropertieies such as metal, pottery and glass are good, however the polyethylene temperature tolerance is still relatively poor, causes its use temperature limited.CN 101570680A has introduced a kind of crosslinkable polyethylene hot-melt adhesive composition and its production and application, make crosslinkable polyethylene pelletizing by adding silane coupling agent, initiator and polar monomer etc., but this method efficient is low, the polyethylene pelletizing that makes itself has certain crosslinked, easily causes binding property to reduce and has lower molten finger.Polyethylene is carried out crosslinked, not only can improve mechanical property, chemical stability, the anti-organic corrosive nature of PE, and improve thermal stability very significantly, can make PE not have tangible fusing point, thereby widen the use field of PE greatly.But for clothes PE hot melt adhesive, the PE after crosslinked is because the lifting of mechanical moduli, causes its pliability to descend and the decline of feel, causes the comfortableness decline of clothes.
CN 1687280A has introduced a kind of new type hot-melt adhesive and preparation method thereof, and recessed soil is filled among the EVA as additive, can reduce product cost significantly, improves the viscosity and the softening temperature of product.It is less that but its softening temperature improves degree, still hinders the use field of hot melt adhesive.CN 1357589A has introduced a kind of multi-purpose polyamide hot melt adhesive and preparation method thereof, with high-molecular weight branched chain type polymeric amide and in the polymeric amide of molecular weight carry out blend, and fill fillers such as a certain amount of white carbon black, lime carbonate or magnesium hydroxide.CN 1401724A has introduced a kind of High-temp.-resistant hot-melt adhesive, with PA is base material, add a certain amount of EVA, rosin, glyceride in addition, and filling nano level aluminium sesquioxide, Nano-class zinc oxide and nano level magnesium oxide, the hot melt adhesive that makes can reach 130 ℃～150 ℃, but still can't satisfy the high temperature needs.
Nano imvite and nanoclay are divided into extensively at occurring in nature, and be of a great variety, and reserve is abundant, is a kind of natural resource of preciousness.They have good dispersing property, can widespread use macromolecular material industry as the additive of nanometer polymer macromolecular material, improve shock resistance, antifatigue, dimensional stability and gas barrier property etc., thereby play the effect that strengthens the comprehensive physicals of polymkeric substance, improve the material processing characteristics simultaneously.Application in polymkeric substance can be added when polymkeric substance, also can blend add (adopting the screw rod blend usually) when fusion.People such as Li Tongnian (nanometer composite polyamide-clay material, the functional polymer journal, the first phase in 2000,112-118) reported the thermal stability of clay and polyamide compoiste material, low clay content (1%～10%) can make the softening point temperature of polymeric amide improve nearly one times.
