Kini emulsion styrene-acrylic

Styrene acrylate emulsion (styrene-acrylate emulsion) jẹ iṣelọpọ lati monomer styrene-acrylate nipasẹ emulsion copolymerization. Styrene-acrylic emulsion jẹ ọkan ninu awọn ọna ṣiṣe polymerization emulsion ti a ṣe iwadi julọ ati ọkan ninu mẹwa awọn emulsions ti kii ṣe agbelebu ti pataki fun awọn ohun elo ile-iṣẹ. Styrene-acrylic emulsion gẹgẹbi agbedemeji kemikali pataki ni ọpọlọpọ awọn ohun elo ti o gbooro pupọ, ti a lo ni akọkọ bi awọn ohun elo ikole, awọn ohun elo latex ti awọn ipele irin, awọn alakoko, awọn adhesives iwe, awọn adhesives, ati bẹbẹ lọ emulsion ni ifaramọ ti o dara, fiimu ti o han gbangba, resistance omi ti o dara. , epo resistance, ooru resistance ati ti ogbo resistance. Styrene-acrylic emulsion ni a lo bi awọn adhesives fun iwe, bakanna pẹlu sitashi, ọti polyvinyl, sodium carboxymethyl cellulose ati awọn adhesives miiran.

Awọn pato

Awọn monomer ti wa ni tuka ni emulsion polymerization lilo ohun emulsifier ninu omi, eyi ti a npe ni emulsion polymerization. A mora emulsion polymerization eto ti wa ni o kun kq ti monomer, omi, omi-tiotuka initiator ati omi-tiotuka emulsifier, ṣugbọn awọn agbekalẹ lo ninu ile ise jẹ Elo siwaju sii eka. Emulsion polymerization jẹ igbagbogbo copolymerization, ni afikun si monomer akọkọ, keji, monomer kẹta le wa.

Awọn anfani ti polymerization emulsion:

(1) omi bi apapọ, olowo poku ati ailewu. Latex ni iki kekere, eyiti o ṣe irọrun gbigbe ooru, gbigbe ati iṣelọpọ ilọsiwaju.

(2) Oṣuwọn polymerization jẹ giga, iwuwo molikula ti ọja naa ga, ati pe polymerization le ṣee ṣe ni iwọn otutu kekere;

(3) O ṣe agbega lilo taara ti latex ati iṣelọpọ awọn ọja ti o ni ibatan ayika bii awọ emulsion, binder, iwe, alawọ, awọn ọja itọju aṣọ, ati bẹbẹ lọ.

Awọn aila-nfani ti polymerization emulsion:

(1) nigbati o ba nilo awọn ọja to lagbara, emulsion gbọdọ lọ nipasẹ awọn ilana ti coagulation, fifọ, dewatering ati gbigbẹ, ati pe iye owo naa ga;

(2) emulsifier ati awọn idoti miiran wa ninu ọja naa, eyiti o nira lati yọkuro patapata, eyiti o bajẹ awọn ohun-ini itanna, ati bẹbẹ lọ.
