Description
Technical field
The invention belongs to chemical and finishing functions of textile fabrics field, especially relate to utilizing and contain HBP-NH
2/ Ag
+The activation solution of coordination compound carries out pre-treatment to fabric, and then carries out the method that the electromagnetic shielding electroless plating is processed.
Background technology
The chemical plating metal fabric is a kind of electromagnetic shielding material of excellent property, the method that it mainly adopts electroless plating with metal deposition such as nickel, copper, silver at fabric face.Compare with other shielding material, it also has the characteristics such as softness, ventilative, light weight concurrently, has a wide range of applications in fields such as electronic product, building, protective clothings.Along with electromagnetic radiation is paid attention to by people gradually to the harm that human body produces, the exploitation of such Electromagnetically shielding fabrics also becomes with application the focus that people study gradually.
The electroless plating of fabric is by reductive agent suitable in solution, and metal ion is reduced under the self-catalysis of precious metal surface, thereby causes the process that metal deposits at fabric face, also is electroless plating, autocatalytic plating.For example, the traditional technology of polyester piece good surface chemical metal plating mainly comprises: deoil, the operation such as alligatoring, sensitization, activation and electroless plating.Deoil, namely remove the greasy dirt of fabric face before electroless plating; The purpose of alligatoring is in order to increase the nano and micro relief of product surface, and then increases contact area and hydrophilic ability, improves the bonding strength of metal and fabric face, often adopts certain density sodium hydroxide solution to carry out roughening treatment to polyester piece good; Sensitization is the fabric after alligatoring to be put into tin protochloride flood; stannic hydroxide or tindihydroxide that the tin salt hydrolysis is generated are deposited on fabric face equably; in the activation procedure that carries out subsequently; stannous ion is reduced into palladium metal with the palladium ion in activation solution; and then making palladium metal be deposited on fabric face formation metal grain or metallic membrane, this layer metallic membrane can provide precondition for ensuing electroless plating reaction.
In the preparation process of whole Electromagnetically shielding fabrics, activating process plays vital effect, and its quality is directly determining the quality of chemical plating.Therefore, the activating process of vast researchers before to chemical plating metal conducts extensive research.Up to the present, the activation method that non-metallic material is adopted mainly contains: (1) SnCl
2And PdCl
2Sensitization-activation two-step approach; (2) colloidal palladium activation method; (3) Palladous chloride direct activation method; (4) ionic palladium activation method.That adopt in industry is mainly SnCl
2And PdCl
2Sensitization-activation method, but this kind method treating processes is very loaded down with trivial details is very likely introduced Impurity Sn in reactivation process and affects the high high-temp stability of palladium film; And similar with Palladous chloride direct activation method to the colloidal palladium activation method, the method is also because only depend on the physical deposition effect to combine between fiber and active palladium, exists that sticking power is weak, caducous defective; And in the method, the consumption of precious metal palladium is large, and utilization ratio is low, and the reactivation process cost is higher.
The ionic palladium activation method is mainly to add certain to have again the carrier compound of stronger adsorptive power to non metallic substrate by complexing palladium ion in palladium chloride solution, base material after alligatoring is immersed in mentioned solution, after with reductive agent, precious metal ion being reduced into precious metal again, just can make substrate material surface have catalytic activity, the method has improved the bonding force of coating and base material well, has reduced pollution.At present, the carrier compound of loaded palladium catalyst mainly contains natural macromolecular material, synthesized polymer material, inorganic materials and organic-inorganic hybrid material etc.; Compare with other carrier compound, the preparation technology of polymer carrier supported catalyst palladium is comparative maturity, simultaneously it also to have catalytic activity high, good stability, the advantages such as easy handling had become academia's study hotspot in recent years.Recently, just someone adopts cm-chitosan (CMCS) as the carrier of palladium ion, the complex compound of itself and palladium ion is used for activating process (application number: 201210153262.2) before the Electromagnetically shielding fabrics electroless plating, but the method is before carrying out activation treatment to fabric, need to carry out roughening treatment to fabric, simultaneously, also need to reduce through reductive agent after activation; Also there is the people that Polyamidoamine Dendrimers (PAMAM) and palladium ion title complex are applied to (application number: 201210086969.6) in the front activating process of Electromagnetically shielding fabrics electroless plating, although the method has been saved the alligatoring operation before the activation, still need after activation to process through reduction.And above method all to adopt precious metal palladium be catalyzer, although the activation effect of precious metal palladium is better, price is very expensive, thereby has caused the raising of Electromagnetically shielding fabrics cost.
In sum, develop a kind of energy-conserving and environment-protective, the activation method that cheap, activation effect is good, have very important significance in the preparation of Electromagnetically shielding fabrics.
Branch-shape polymer is the novel high molecular polymer of a class that is born afterwards the eighties in 20th century, compare with traditional linearity, branching, crosslinked base polymer, have branch-shape polymer three-dimensional highly branched structure, molecular end contain a large amount of reactive functional groups, intramolecule and have opening structure, solubleness is high, viscosity is low, have structure and unique performance of such novelty just because of this base polymer, nearest two have become one of study hotspot of field of polymer technology during the last ten years.Branch-shape polymer can be divided into again dendrimer and the large class of hyperbranched polymer two by its structure; although two base polymers have closely similar structure and performance; but in the synthetic polymer process; dendrimer need to pass through polystep reaction; each step reaction all needs through special protection, goes the steps such as protection, purification; process is comparatively loaded down with trivial details; be unfavorable for industrial production and application; and hyperbranched polymer is synthetic; do not need synthetic through multistep and purify; one step can synthesize, and preparation process is simple, was conducive to large-scale production and application.Ultrabranching polyamide-amine (HBP-NH
2) be a kind of in hyperbranched polymer, contain a large amount of functional group that contains N (as primary amine, secondary amine, tertiary amine, acid amides etc.) in this quasi-molecule, intramolecule has cavity structure.Can pass through chemisorption, in the surface group and internal cavities of polymer macromolecule, therefore, this base polymer can be used as the carrier compound of metal catalyst with adsorption of metal ions.
At present, in the activating process of fabric chemical plating metal, the noble metal catalyst that adopts is mainly palladium metal, i.e. Palladous chloride type activation solution, the good stability of this activation solution, do not keep in dark place, occasion construction in the open all has catalytic activity to copper and mickel, but the activating process more complicated, the source is rare simultaneously, and is expensive; Except palladium metal, adopt argent as catalyzer in the non-metallic material activating process, it is Silver Nitrate type activation solution, copper etc. also had good catalytic activity, it coordinates the plating pre-treatment that can be fit to multiple non-metallic material with electroless copper, the sources such as while Silver Nitrate are wide, and cost is lower, has very wide using value in the processing of metallization Electromagnetically shielding fabrics.
