PU (polyurethane-type) hot melt adhesive, namely with polyurethane resin or prepolymer for material of main part, and with various auxiliary agent for the hot melt adhesive obtained as tackifier, catalyst, antioxidant and filler etc. of preparing burden.Chemical crosslinking in polyurethane-type hot melt adhesive chemical constitution does not have or seldom, its molecule is line style substantially, owing to containing more polar group as strong in ester group, ether, carbamate groups, urea groups, biuret groups and allophanate group etc. in molecule, the high forces existed between these group Molecule and hydrogen bond form physical crosslinking.This polyurethane-type hot melt adhesive can lose the physical crosslinking effect in polyurethane molecular after being heated, and becomes the gluing liquid of melting, recovers again original physical property after cooling.Therefore, polyurethane-type hot melt adhesive has excellent elasticity and intensity, high bond strength, solvent resistant, high temperature resistant, ageing-resistant, wear-resisting, is applicable to the bonding of a lot of material, is particularly suitable for bonding footwear and fabric.PU glue is not containing penetrating odor organic solvents such as toluene, free from environmental pollution during use, belong to environmental friendliness shaped material, therefore deeply favor by people, this hot melt adhesive for weaving, shoemaking, books unsewn binding, packaging for foodstuff, the assembling of wooden industry, building, the field such as automobile component is bonding, has a extensive future in a large number.
In general, polyurethane-type hot melt adhesive can be divided into two classes: a class is Polyurethane Thermoplastic Elastomer hot melt adhesive, can be described as again hot melt type polyurethane hot melt adhesive; Another kind of is reaction type polyurethane hot-melt adhesive.By cooling curing after the former is heats liquefied, solidified by cooling and moisture cross-linking reaction after the latter is heats liquefied.
Hot melt type polyurethane hot melt adhesive mainly utilizes the effect generation materialization of hydrogen bond in composition to be cross-linked, and can lose the effect of hydrogen bond, become the viscous fluid of melting, recover again original characteristic after cooling after being heated.Utilize this characteristic, can be made into high bond strength, wear-resisting hot melt adhesive.
Crystallisation solidification is the key technology that polyurethane nethike embrane is produced, application number be 201310485209.7 Chinese invention patent application disclose a kind of Polyurethane hot-melt adhesive tape and preparation method thereof, application number be 201310132982.5 Chinese invention patent application disclose a kind of TPU hot melt adhesive film production equipment, all adopt water logging crystallisation by cooling, adopt this kind of technique, in hot-melt adhesive film production, the crystallisation solidification of nethike embrane is slow, affects speed of production, yielding adhesion after winding shaping.
