Txij li thaum daim ntawv thov ntawm pigment printing ntawm textiles nyob rau hauv nruab nrab -1950s, kuv lub teb chaws tau undergone kev txhim kho thiab innovation, tab sis cov kev tshawb fawb ntawm tshwj xeeb pigment printing pastes tau qeeb thiab cov nyhuv tsis zoo.
Cov txheej txheem ua ntej emulsification yog emulsify ib feem ntawm cov monomers ntawm chav tsev kub ua ntej nkag mus rau lub reactor, kom cov organosiloxane thiab acrylate tuaj yeem tsim tau zoo rau hauv monomer particles adsorbed los ntawm emulsifier, thiab cov dispersion kuj zoo ib yam. Thaum nws maj mam ntxiv rau cov tshuaj tiv thaiv kab mob rau cov tshuaj tiv thaiv tshuaj, cov tshuaj tiv thaiv polycondensation ntawm organosiloxane nws tus kheej thiab cov tshuaj tiv thaiv dawb radical copolymerization ntawm nws thiab cov acrylate tshwm sim ib txhij. Nyob rau lub sijhawm no, cov emulsifier adsorbed ntawm cov khoom monomer maj mam Hloov mus rau saum npoo ntawm latex hais kom muaj kev ruaj ntseg ntawm cov txheej txheem polymer tshiab tsim los ntawm cov tshuaj tiv thaiv, txo cov gel tiam, thiab thaum kawg tsim ib copolymer emulsion zoo ib yam thiab ruaj khov.
Kev hloov kho ntawm acrylate nrog 5% mus rau 10% ntawm silicone monomer tuaj yeem ua rau cov xim hluavtaws luam ntawv nplaum zoo li mos thiab du. Ntxiv 2% mus rau 4% ntawm N-methylol acrylamide tuaj yeem txhim kho qhov nrawm nrawm ntawm cov xim luam ntawv nplaum. Anionic/nonionic composite emulsification system (1:3) noj 3%-4%, butyl acrylate ntau npaum 50%-75%, ethyl acrylate ntau npaum 20%-30%, acrylonitrile noj 10%{ {14}}%, styrene Qhov ntau npaum li cas ntawm 5% mus rau 10%, qhov ntau npaum ntawm acrylic acid yog 2% mus rau 4%, thiab cov organic siloxane thiab reactive monomer ntxiv. Synthesized xim luam ntawv nplaum muaj kev ua haujlwm zoo thiab ruaj khov. Cov txheej txheem ua ntej emulsification ntawm kev sib xyaw organosiloxane thiab acrylic monomers tuaj yeem ua rau cov txheej txheem polymerization muaj kev nyab xeeb thiab du, cov khoom siv polymer ruaj khov, thiab tsis muaj gel thiab oily tshwm sim.
