Grafted copolymer ntawm chloroprene roj hmab thiab methyl methacrylate (MMA). Grafted adhesive yog ib hom nplaum ua los ntawm grafting chloroprene roj hmab (CR) thiab methyl methacrylate (MMA). Nyob ntawm nws daim ntawv thov, nws tuaj yeem muab faib ua ntau hom, xws li cov nplaum ntshiab grafted, cov nplaum nplaum sib xyaw, thiab cov nplaum nplaum tawv tawv. Los ntawm kev qhia PMMA sab chains rau hauv cov saw tseem ceeb, nws txhim kho kev sib raug zoo nrog cov ntaub ntawv xws li PVC, inhibits plasticizer tsiv teb tsaws, thiab txhim kho cov adhesion durability ntawm substrates xws li tawv tawv. Nws cov khoom tseem ceeb suav nrog chloroprene roj hmab, MMA monomer, pib, thiab tackifying resin. Cov txheej txheem synthesis yuav tsum muaj kev tswj hwm ntawm qhov tsis xws li qhov kub thiab txias (85 degree), pib noj (1.0% ntawm CR huab hwm coj), CR rau MMA huab hwm coj piv (1: 0.6), thiab tiv thaiv nitrogen. Ib pawg-poob ntxiv ntawm MMA cov tshuaj yog siv los ua kom cov grafting tus nqi mus rau 21.3%.
Cov nplaum no muaj cov viscosity tsawg (4000-5000 mPa·s), muaj zog nkag, thiab ruaj khov zoo. Nws lub zog sib txuas yog ze rau ntawm polyurethane adhesives, tab sis ntawm tus nqi qis. Nws yog dav siv hauv kev lag luam khau thiab hnab thiab tsim nyog rau kev sib txuas cov ntaub ntawv xws li PVC, PU, ABS, EVA, fabrics, thiab tawv tawv. Nws tuaj yeem siv los ntawm txhuam los yog tshuab. Tom qab ob daim ntawv thov, nws yuav tsum tau qhuav ntawm 70℃rau 4-6 feeb ua ntej kev sib txuas siab. Kev tswj xyuas qhov kub thiab txias, qhov nplaum daim ntawv thov nyiaj, thiab lub sij hawm ziab yog qhov tseem ceeb los tiv thaiv delamination lossis nplaum nplaum. Cov xim tuaj yeem hloov pauv vim muaj tshuaj lom neeg thaum lub sijhawm khaws cia, thiab qhov adhesion tau yooj yim cuam tshuam los ntawm qhov kub thiab txias ntawm qhov kub thiab txias. Qhov ntsuas kub yuav tsum tau khaws cia ntawm 5 txog 30 degree.
