作为本发明所述脱醇型硅酮胶的优选,所述有机钛Tyzor催化剂为726。
本发明的发明构思及益效果:
(1)选取高CaCO3含量石灰石,在较高温度煅烧,获得原生粒子大、表面较光滑的石灰,煅烧石灰检测草酸活性控制在5′-10′。
(2)高温消化,保温50℃-70℃陈化放置100h-150h,利于石灰颗粒的完全消化。
(3)超重力碳化反应器并联,加快反应速度,使纳米碳酸钙生成速度大于生长速度,粒径小,原生粒径大小可以通过反应器并联台数调控。
(4)碳化过程使用高浓度CO2气体,提高Ca(OH)2与CO2反应合成速度。
(5)结束碳化前加入有机分散剂、阴离子分散剂或二者的混合物,阴离子分散剂起电荷互相排斥作用,有机分散剂吸附在颗粒表面时,形成的层状结构可以有效阻止颗粒之间的接触和聚焦,起到空间位阻的效果,两种分散效果协同效应,使纳米碳酸钙颗粒凝聚性降低,团聚减少。
(6)加热碳化液加入改性剂I,使碳酸钙由亲水性变为疏水性,具体为C16-C20的脂肪酸及盐、磺酸盐有直链烷基苯磺酸钠和α-烯基磺酸钠、高级磷酸酯有磷酸单烷基酯、磷酸二烷基酯和磷酸三烷基酯及螯合型钛酸酯偶联剂,前三种任意一种和螯合型钛酸酯偶联剂混合使用,前三种常规改性剂提高纳米碳酸钙产品的分散性和亲油性,偶联剂则提高纳米碳酸钙在胶中的粘接性、触变性。
(7)二次改性为干法连续改性,改性剂II为钛酸酯偶联剂和硅烷偶联剂,滴加作用为进一步提高物料性能,提高制胶应用中的填加量、伸长率、贮存稳定性、增加与胶料的结合力,提高胶粘剂的粘接力。
(8)所得纳米碳酸钙产品孔径为25-35nm,试验证明此范围内的纳米碳酸钙产品具有一定的粘接吸附性,且不会因孔径过大,经放置渗透后,导致粘度增大,贮存性下降。
(9)所得纳米碳酸钙产品BET为15-22m2/g,水分≤0.3%,pH值8.5-9.5,挤出量60-90g/min,孔径为25-35nm,激光粒度D50<1.0um,D100<5.0um。比表适中、水分、pH值低,能有效降低胶粘剂模量,高挤出量能提高胶粘剂伸长率,孔径均一,激光粒度小,说明产品粒度均一,分散好。
