Ka 2025, lintlafatso tsa indasteri mabapi le ntlafatso ea foromo, phetoho ea lik'hemik'hale, le moralo oa ts'ebetso li kentse matla a macha lekaleng lena.
Ho tebisa Sistimi ea Motheo: Ho tloha ho "Ratio Tuning" ho isa "Performance Balance"
Joaloka "moeta-pele oa ts'ebetso" har'a liaparo tsa hona joale tse nang le metsi, likarolo tse peli tsa metsi a polyurethane (WB 2K-PUR) li tobane le phephetso ea mantlha: ho leka-lekanya karo-karolelano le ts'ebetso ea mekhoa ea polyol. Selemong sena, lihlopha tsa lipatlisiso li ile tsa etsa lipatlisiso tse tebileng ka liphello tsa synergistic tsa polyether polyol (PTMEG) le polyester polyol (P1012).
Ka tloaelo, polyester polyol e eketsa matla a mochini le letsoalo ka lebaka la li-intermolecular hydrogen bond, empa tlatsetso e feteletseng e fokotsa ho hanyetsa metsi ka lebaka la hydrophilicity e matla ea lihlopha tsa ester. Liteko li netefalitse hore ha P1012 e etsa karolo ea 40% (g / g) ea tsamaiso ea polyol, "ho leka-lekana ea khauta" e finyelloa: li-hydrogen bond li eketsa boima ba 'mele oa crosslink ntle le hydrophilicity e feteletseng, ho ntlafatsa ts'ebetso e feletseng ea ho roala-ho akarelletsa le ho hanyetsa letsoai, ho hanyetsa metsi le matla a thata. Qeto ena e fana ka tataiso e hlakileng bakeng sa moralo oa motheo oa WB 2K-PUR, haholo-holo bakeng sa maemo a kang chassis ea likoloi le likarolo tsa tšepe tsa koloi ea terene tse hlokang ts'ebetso ea mochini le ho hanyetsa ho bola.
"Ho Kopanya ho Tiea le ho Fetoha": Phetoho ea Lik'hemik'hale e Bula Meeli e Mecha ea Mosebetsi
Le hoja ho ntlafatsa karo-karolelano ea motheo e le "tokiso e ntle," phetoho ea lik'hemik'hale e emela "boleng ba boleng" bakeng sa polyurethane ea metsi. Litsela tse peli tsa phetoho li ile tsa hlahella selemong sena:
Tsela ea 1: Ntlafatso ea Synergistic ka Polysiloxane le Terpene Derivatives
Motsoako oa "low-surface-energy polysiloxane (PMMS) le hydrophobic terpene derivatives e fa WPU e nang le thepa e 'meli ea "superhydrophobicity + high rigidity." Bafuputsi ba lokiselitse hydroxyl-terinated polysiloxane (PMMS) ba sebelisa 3-mercaptopropylmethyldimethoxysilane le octamethylcyclotetrasiloxane, eaba ba hlomathiseletsoa isobornyl acrylate (e nkiloeng ho camphene e entsoeng ka biomass) holim'a liketane tsa mahlakoreng a PMMS ka UV-initiated thiol-PMMS e thehiloeng ho thiol-PMMS e thehiloeng ho thiol-PMS
WPU e fetotsoeng e bonts'itse lintlafatso tse tsotehang: static water contact angle angle tlole ho tloha 70.7 ° ho 101.2 ° (ho atamela lotus-like superhydrophobicity), ho monya metsi ho theohile ho tloha ho 16.0% ho ea ho 6.9%, 'me matla a matla a ile a phahama ho tloha 4.70MPa ho ea ho 8.82MPa ea ringpeter. Tlhahlobo ea Thermogravimetric e boetse e senotse botsitso bo matlafalitsoeng ba mocheso. Theknoloji ena e fana ka tharollo e kopantsoeng ea "anti-fouling + weather-resistant" bakeng sa likarolo tse ka ntle tsa literene tse kang liphanele tsa marulelo le li-skirts tse mahlakoreng.
Tsela ea 2: Polyimine Crosslinking e nolofalletsa Theknoloji ea "Ho Iphekola".
Ho ipholisa ho hlahile e le theknoloji e tsebahalang ea ho roala, 'me lipatlisiso tsa selemo sena li e kopantse le ts'ebetso ea mochini oa WPU ho fihlela katleho e habeli "ts'ebetsong e phahameng + ea ho ipholisa." Crosslinked WPU e lokiselitsoeng ka polybutylene glycol (PTMG), isophorone diisocyanate (IPDI), le polyimine (PEI) e le crosslinker e bonts'a thepa e tsotehang ea mochine: matla a tsitsitseng a 17.12MPa le elongation nakong ea khefu ea 512.25% (haufi le ho feto-fetoha ha rabara).
Habohlokoa, e finyella ho ipholisa ka ho feletseng ka lihora tsa 24 ho 30 ° C-ho hlaphoheloa ho 3.26MPa matla a matla le 450.94% elongation ka mor'a ho lokisoa. Sena se e etsa hore e tšoanelehe haholo bakeng sa likarolo tse tloaelehileng tse kang li-bumpers tsa likoloi le lipalangoang tsa terene, ho fokotsa litšenyehelo haholo tsa tlhokomelo.
"Nanoscale Intelligent Control": "Phetohelo ea Bokaholimo" bakeng sa Liaparo tse Khahlanong le Fouling
Anti-graffiti le ho hloekisa habonolo ke litlhoko tsa bohlokoa bakeng sa liphahlo tse phahameng. Selemong sena, lesela le thibelang litšila (NP-GLIDE) le thehiloeng ho "liquid-like PDMS nanopools" le ile la khahla tlhokomelo. Molao-motheo oa eona oa mantlha o kenyelletsa ho hlomathisa liketane tsa mahlakoreng a polydimethylsiloxane (PDMS) holim'a mokokotlo oa polyol o qhalakantsoeng ka metsi ka graft copolymer polyol-g-PDMS, e etsang "nanopools" e nyane ho feta 30nm bophara.
Ntlafatso ea PDMS ho li-nanopools tsena e fana ka ho roala "joaloka mokelikeli" holim'a metsi-tsohle tse nang le metsi a lekang ka holimo ho 23mN/m (mohlala, kofi, matheba a oli) a thella ntle le ho siea matšoao. Ho sa tsotellehe boima ba 3H (haufi le khalase e tloaelehileng), ho roala ho boloka ts'ebetso e ntle ea ho thibela litšila.
Ho phaella moo, ho ile ha etsoa tlhahiso ea leano la "thibelo ea 'mele + ho hloekisa ka bonolo": ho kenyelletsa trimer ea IPDI ho polyisocyanate e thehiloeng ho HDT ho matlafatsa sekhahla sa filimi le ho thibela ho kenella ha graffiti, ha ho ntse ho laola ho falla ha likarolo tsa silicone / fluorine ho etsa bonnete ba hore matla a tlaase a nako e telele a tlaase. E kopantsoe le DMA (Dynamic Mechanical Analysis) bakeng sa taolo e nepahetseng ea "crosslink density control" le XPS (X-ray Photoelectron Spectroscopy) bakeng sa sebopeho sa ho falla ha sehokelo, theknoloji ena e se e loketse ntlafatso ea indasteri 'me e lebelletsoe ho fetoha letšoao le lecha la ho thibela ho silafala ha pente ea likoloi le likhase tsa lihlahisoa tsa 3C.

Ka 2025, theknoloji ea ho roala ea WPU e tloha ho "ntlafatso ea ts'ebetso e le 'ngoe" ho ea "kopanong ea mesebetsi e mengata." Ebang ke ka ntlafatso ea mokhoa oa motheo, katleho ea phetoho ea lik'hemik'hale, kapa mekhoa e mecha ea meralo, moelelo oa mantlha o mabapi le ho hokahanya "botsoalle ba tikoloho" le "ts'ebetso e phahameng." Bakeng sa liindasteri tse kang tsa likoloi le tsa literene, tsoelo-pele ena ea thekenoloji ha e atolose nako ea bophelo ba ho koahela le ho fokotsa litšenyehelo tsa tlhokomelo, empa hape e tsamaisa lintlafatso tse peli ho "tlhahiso e tala" le "boiphihlelo bo phahameng ba basebelisi."
