Tlhaloso

Hona joale, ho na le likarolo tse peli tsa lipatlisiso mabapi le ho fetoloa ha liphahlo tsa alkyd resin: ho fetola resin le ho fetola pigment.Phetoho ea resin ke ho hlahisa lihlopha tse ling karolong ea resin molecular chain, kapa ka polyurethane resin, acrylic resin, epoxy resin le silicone resin.Phetoho ea pigment le filler haholo-holo ke ho kenyelletsa mebala e fapaneng e sebetsang le li-filler ho ntlafatsa ts'ebetso ea liphahlo tsa alkyd resin.Pampiri ena e hlahisa thuto mabapi le ho fetoloa ha liphahlo tse peli tsa metsi a alkyd resin.

1. Ho lokisoa ha oli-water alkyd resin ho tsoa ho peo ea Zanthoxylum bungeanum ka ho senyeha ha libotlolo tsa litšila tsa polyethylene terephthalate (PET)
Lei Rui oa Shaanxi University of Science and Technology, joalo-joalo o lokiselitse peō ea alkyd e entsoeng ka oli ea metsi ea Zanthoxylum bungeanum ka ho sebelisa libotlolo tsa litšila tsa PET, trimethylolpropane (TMP) le oli e sa jeoang ea Zanthoxylum bungeanum e le lisebelisoa tsa mantlha, phthalic anhydride. PA) e le monoma ea acidic, 2,2-Dimethylolpropionic acid (DMPA) e le monoma e nang le metsi, le n, N-Dimethylethanolamine e le moemeli oa ho fokotsa.Liphetho tsa tlhahlobo ea ts'ebetso ea ho roala li bontša hore ha joala bo le 11.5%, oli ea oli ke 50%, w (PET) = 9.3%, w (DMPA) = 10%, ho roala ho na le botsitso bo botle ba polokelo, le metsi. ho hanyetsa, ho thatafala le botsitso ba mocheso li ntlafala haholo ha li bapisoa le alkyd e tloaelehileng ea metsi.
2. Silicone acrylate polyurethane e fetotsoeng e nang le metsi alkyd anticorrosive coating
Resin ea alkyd e ile ea lokisoa ke esterification reaction with tall oil fatty acid (TOFA), pentaerythritol le PA e le lisebelisoa tsa mantlha tse tala, ebe ho eketsoa emulsifier AE 300 ho fumana phallo ea metsi alkyd.Mokelikeli o nang le metsi a polyurethane prepolymer o ne o lokisitsoe ho tloha diol e senyehileng, isophorone diisocyanate le aqueous monomer 2,2-dihydroxymethylpropionic acid (DMPA).Silicon acrylic polyurethane lotion e ile ea lokisoa ka ho sebelisa TEA e le ntho e sa tsitsang, ho eketsa monoma ea acrylic, emulsifier, silane coupling agent, initiator le chain extender.Sekoaelo sa silicone sa acrylic polyurethane se fetotsoeng ka metsing se ile sa lokisoa ka ho hasana ka metsi a alkyd le silicone acrylic polyurethane lotion e le lisebelisoa tsa mantlha tsa ho etsa filimi.
