Antioxidant 1520

Ao1520

Antioxidant 1520 (2, 4-BIS (n-thylthiomethylene) -6-methylphenol) ni ubwoko bushya bwa Antioxides, hamwe na phenoloxyl ya pheol nibindi, gukumira ogisijeni, ubushyuhe, urumuri rwinshi cyangwa imizi yingufu zingufu kubinyabuzima. By'umwihariko, Antioxident 1520 irashobora gukoreshwa mu kurwanya okiside mu gihe cyo kubikamo ibice by'ubwoga, kugira ngo bikarinde ububiko bwa Butadiene muri STITERE Irinde gushinga gel muri Elastomers kandi wihariye uvanga ibara ryamabara mugihe cyo kubika no gutwara abantu.

Gusaba

AntioxidIdent 1520 ni uburemere bushya bwa moleculay antioxidant, cyane cyane ikoreshwa muri Butadiene Rubber, Stylene Butadiene Rubber, Itlene Butadiene Rubber, Impinduka ya Antioxment Nintinti, imenye impinduka zikomoka kuri reberi kuva kwisi yose icyatsi.

Uburyo bwa Synthesis

Kugeza ubu, uburyo bwa synthesis bwa antioxident 1520 ni Motnich uburyo bwa Alkali, ni ukuvuga, methylphenol, n-methylmerictap, formaldehyden cyangwa formaldehdehyde yabonye na mannich reaction.

Uburyo bwa synthesis yavuzwe haruguru burimo inzira ebyiri mubikorwa byukuri, imwe-methylphenol hamwe na polyformalamine ya mbere yo gutegura mannineldehyde 2-methathine, hanyuma ukemure methyl Gusukura uburyo bwibicuruzwa, uzwi kandi nkuburyo bubiri. Ubusanzwe ubutada burimo US3832328, EP428973A1, US5116894, hagomba gukoresha inzira ya Dimethylamine, kandi hakenewe gahunda yo kwitegura ubu buryo

Uburyo bwa synthesie yerekeranye na Antioxident 1520 igizwe nintambwe zikurikira:

1) O-Cresol, N-octylmerCaptan, formaldehyde, Diethanolamine na Solvem byongewe kuri reaction, hanyuma wongere wongere guhindura phi kugeza kuri 1-5 kugirango usuzume reaction;

2) gukonja no guhagarara kugirango bigaragaze, kurangiza icyiciro cyamazi yo hepfo ya react, hanyuma ongeraho ihiomethane na cui, hanyuma usubize gukora reaction;

3) Cool, filteri kugirango ukureho ikibazo kidashoboka, ongeramo umubare ukwiye wa Piccique hanyuma usubiremo 30-60 ℃, ukangura;

4) Nyuma yo koza n'amazi, gutandukanya vacuum, kumisha, byiteguye.

Qingdao Yihoo Polymer Technolog Co. LTD. yiyemeje gukora no gutanga ibitekerezo bitandukanye bikoreshwa muri plastiki no kurera. Ubwoko bwibicuruzwa bikubiyemo antioxidants, stabilizers yoroheje, UV Abadashishoje, ibiti bya flame, nibindi, nibicuruzwa byabonye abakiriya barenga 100 bo mumahanga.
