CONCLUSIES
1. Synergetische warmtestabilisator, waarbij: een organotinverbinding is gebruikt als primaire warmtestabilisator; en een butyltitanaat gemodificeerd ceriummetaalzeepcomplex is gebruikt als hulpstabilisator, en de butyltitanaat als koppelingsmiddel een merkbaar synergetisch stabiliserend effect heeft op de organotin verbinding en de ceriummetaalzeep en effectief de thermische stabiliteit van PVC kan verbeteren.
2. Synergetische warmtestabilisator volgens conclusie 1, waarbij: het bestanddeel van de ceriummetaalzeep ceriumstearaat is.
3. Synergetische warmtestabilisator volgens conclusie 1 of 2, omvattende de volgende componenten: 1,0-5,0 gewichtsdelen butyltitanaat, 1,0-5,0 gewichtsdelen ceriummetaalzeep en 0,1-1,0 gewichtsdelen organotinverbinding warmtestabilisator.
4. Synergetische warmtestabilisator volgens conclusie 3, omvattende de volgende componenten: 1,0-5,0 gewichtsdelen butyltitanaat, 1,0-5,0 gewichtsdelen ceriummetaalzeep en 0,5 gewichtsdelen organotinverbinding blik warmtestabilisator.
5. Synergetische warmtestabilisator volgens conclusie 1, die wordt bereid volgens een werkwijze die de volgende stappen omvat: het mengen en oplossen van 50 gewichtsdelen DOTP, 1,0-5,0 gewichtsdelen butyltitanaat, 1,0-5,0 gewichtsdelen ceriummetaalzeep en 0,1-1,0 gewichtsdelen organotinverbinding warmtestabilisator door microgolfstralingstechnologie; en vervolgens het plaatsen van het mengsel in een glazen container en het starten van een gemengde microgolfstraling in een magnetron om gedurende 15 minuten voor het verkrijgen van een uniforme synergetische warmtestabilisator voorloper.
6. Synergetische warmtestabilisator volgens conclusie 5, waarbij: het vermogen van de magnetron 700W is.
7. Toepassing van de synergetische warmtestabilisator volgens conclusie 1, 2 of 5, waarbij: de synergetische warmtestabilisator wordt toegevoegd aan een PVC gebaseerde-
substraat om de thermische stabiliteit van het PVC-materiaal te verbeteren, waarbij de verhouding van elke component is: 100 gewichtsdelen PVC-hars, 1,0-5,0 gewichtsdelen butyltitanaat, 1,0-5,0 gewichtsdelen ceriummetaalzeep en 0,1-1,0 gewichtsdelen organotinverbinding warmtestabilisator.
8. Applicatie volgens conclusie 7, waarbij: de synergetische warmtestabilisator voorloper wordt vermengd met het PVC- basismateriaal, en het mengsel wordt geroerd op hoge snelheid om het voormengsel te verkrijgen; en vervolgens het voormengsel wordt blootgesteld aan banbury-mengen in een banburymenger; en het banbury-mengen is voltooid nadat het koppel sterk stijgt en vervolgens daalt en onveranderd blijft, en het gemengde materiaal wordt eruit gehaald en wordt onderworpen aan tabletteren gedurende 40 seconden in een vulkaniserende pers bij 100 °C, voor het verkrijgen van een PVC-plaat met een dikte van 1 mm.
9. Applicatie volgens conclusie 8, waarbij: gedurende het banbury-mengen wordt een smelttemperatuur op 170-175 °C, schroefdraaisnelheid op 40 omwentelingen/min, en een banbury-mengtijd op 2-3min geregeld.
