Description
Technical field
The present invention relates to the production of adhesive technical field, particularly a kind of solvent-free polyurethane adhesive preparation and application thereof.
Background technology
Along with the superior requirement to cloth of clothes is more and more higher, common textile cloth has been difficult to satisfy the demand.By sticking with glue agent that the cloth of different sorts, different feels is compound, make it compare the performance that possesses a lot of excellences with the single variety cloth, smooth such as cloth performance feel exquisiteness, outward appearance is plentiful, windproof, ventilative, style is novel, unique, possesses certain water-proof function, and heat retention is good, the aspects such as wear resistance, elastic restoration ratio, intensity all can improve simultaneously, are desirable garment materials.
The compound main employing solvent borne polyurethane tackiness agent of current cloth, although adopt this tackiness agent can obtain all good products of various aspects of performance, but because the course of processing has a large amount of solvent evaporates, inflammable and explosive, the healthy and safe of workmen damaged, also environment has been caused severe contamination simultaneously.If in tackiness agent, do not use solvent, then can address these problems.
Compound for cloth, as usually to adopt roller to be coated with technique, tackiness agent (such as 80 ℃) under construction temperature is in a liquid state, and has certain viscosity, is cooled to room temperature (25 ℃) after the coating and is solid-state, makes compound cloth typing.
The urethane resin molecular chain has soft section and hard section, and hard section affects the softening melt temperature of resin usually.Hard section of urethane is comprised of reacted polyisocyanates or polyisocyanates and chainextender, contains carbamate, replaces urea groups isopolarity group.Polyisocyanates and chainextender are very large on hard section composition impact, usually hard section softening temperature of aromatic polyisocyanate reaction generation is higher than aliphatic polyisocyanates, short by molecular chain, without side group, the hard section softening melt temperature that the chainextender that polarity is strong and polyisocyanates reaction generate is high, if instead the chainextender molecular chain length has side group, polarity is low, and the hard section softening melt temperature that then generates is just low.In addition, the softening melt temperature of urethane resin improves along with the increase of molecular weight within the specific limits, and simultaneously the molecular weight of urethane also affects the viscosity of melts, when its molecular weight less than a certain critical molecular weight M
cThe time, zero of its melt is cut viscosity and is directly proportional with weight-average molecular weight; When molecular weight greater than M
cThe time, zero cuts viscosity sharply increases with the increase of molecular weight, generally is directly proportional with 3.4 powers of weight-average molecular weight.Regulate the composition of urethane resin soft or hard section and the molecular weight of urethane resin by the kind and the proportioning that change polyisocyanates, chainextender, polyester polyol, can control melt temperature and the melt viscosity of urethane resin, make it satisfy the compound processing requirement of roller coating.
Because cloth also has the demand of the aspect of performances such as washing, flatiron, fastness in use, simple thermoplastic resin is difficult to satisfy, and need to add solidifying agent in tackiness agent, curing cross-linked adult form structure, temperature tolerance is good, presses indeformable, washing fastness is good, reaches best use properties.
