Abstract
The invention discloses high-air permeability dimer acid type polyamide hot melt adhesive and a preparation method thereof. Dimer acid, aliphatic dicarboxylic acid and aliphatic diamine which are used as reaction raw materials and other aids such as modifier are subjected to polymerization reaction at certain temperature and under certain pressure, and permeability modifier is added at the later stage. According to the method, the special raw materials are used in the synthesis process, and the permeability modifier is added at the later stage of synthesis, so that the air permeability of the prepared dimer acid type polyamide hot melt adhesive is improved obviously. The product is particularly suitable for occasions with the high requirement on air permeability, such as adhesive for clothes.
Description
Technical field
The present invention relates to a kind of highly air-permeable dimeric acid type polyamide hot melt adhesive and preparation method thereof, be particularly suitable for the industry higher, use hot melt adhesive like high-grade clothing to ventilation requirement.
Background technology
Dimeric acid type polyamide hot melt adhesive is a kind ofly to be produced through polycondensation by dimerization unsaturated aliphatic or the substituted dimerization unsaturated fatty acids of part and aliphatic diamine.
Chinese patent CN10130721 discloses a kind of high temperature resistant water washing polyamide hot-melt adhesive for clothes and preparation method thereof, and it passes through dicarboxylicacid, and prepared in reaction such as monocarboxylic acid, aliphatic diamine, lactan, water and stablizer obtain.It has the excellent properties of high temperature resistant water washing.
Chinese patent CN101126007 discloses polyamide thermosol for clothing and preparation method thereof; Its polycondensate through in traditional copolyamide hot melt adhesive, adding TMSDEA N diethylamine propyl group octadecyl acid amides and appoint basic phenol, formaldehyde and tetraethylenepentamine, characteristics such as molecular weight ranges is narrow, quick solidifying, water-fast solvent resistance excellence that it has.
Chinese patent CN101705073A discloses a kind of polyamide hot that is obtained by soybean oil-based dimeric acid, aliphatic dicarboxylic acid, aliphatie diamine, aromatic diamine, lactan, molecular weight regulator, the polycondensation of water joint catalyzer.It has excellent physics and chemical properties such as lower melting point, anti-solvent, viscosity are good.
Though the polyamide hot that above-mentioned and so on patent is mentioned all has an excellent separately performance; But it still has deficiency; What for example patent CN10130721 and CN101126007 told all is copolymerization acid type polyamide hot, has the shortcomings such as shortcoming wash durability deficiency of copolyamide hot melt adhesive; It has added soybean oil-based dimeric acid as reaction raw materials patent CN101705073A in raw material; Can make the wash durability of product be significantly improved; But the compound method of its use still is traditional employed high-pressure process of copolyamide hot melt adhesive, and its reaction process is comparatively complicated.The product that no matter above that piece patent is introduced simultaneously, though its different performance to polyamide hot has been done modification, its permeability to product is not all done modification.
