相关申请的交叉参考
根据35U.S.C.§119(e),本申请要求2008年3月4日提交的美国临时专利申请序列号No.61/033447的权益。美国临时专利申请序列号No.61/033447在此通过参考引入。
发明领域
本发明涉及硅氧烷组合物,和更特别地涉及包含至少一种每一分子平均具有至少两个与硅键合的氢原子的有机基氢聚硅氧烷,每一分子平均具有至少两个脂族碳-碳双键的交联剂,和氢化硅烷化催化剂的硅氧烷组合物。本发明还涉及包含至少一种有机基氢聚硅氧烷的固化产物的硅氧烷粘合剂。本发明进一步涉及涂布的基底和层压的基底,其中各自包括所述硅氧烷粘合剂。
发明背景
硅氧烷粘合剂因其独特的性能的结合,其中包括高热稳定性、良好的耐湿性,优良的挠性,高的离子纯度,低的α粒子发射,和对各种基底良好的粘合性,因此可用于各种应用。例如,硅氧烷粘合剂广泛用于机动车、电子、建筑、器具和航空工业上。
然而,当常规的硅氧烷粘合剂暴露于高温下,例如与开放式火焰直接接触而遇到的高温下时,该粘合剂分解,形成焦炭,典型地一种不粘附的粉末。
鉴于前述问题,需要一种硅氧烷组合物,它固化形成具有高的焦炭产率和在暴露于比粘合剂的分解温度高的温度下之中和之后具有高的粘合性的粘合剂。
发明概述
本发明涉及一种硅氧烷组合物,它包含:
(A)至少一种通式为(R1 2R2SiO1/2)m(R1R2SiO2/2)n(R1SiO3/2)p(I)的有机基氢聚硅氧烷,其中每一R1独立地为C1-C10烃基或C1-C10卤素取代的烃基,二者均不含脂族不饱和键,每一R2独立地为R1或-H,m为0.001-0.3,n为0.5-0.999,p为0-0.5,和m+n+p=1,条件是该有机基氢聚硅氧烷每一分子平均具有至少两个与硅键合的氢原子;

(C)氢化硅烷化催化剂。
本发明还涉及包含至少一种具有上式(I)的有机基氢聚硅氧烷的固化产物的硅氧烷粘合剂。
本发明进一步涉及涂布的基底,它包括:
基底;和
在基底表面的至少一部分上的硅氧烷粘合剂涂层,其中该粘合剂涂层包括至少一种具有上式(I)的有机基氢聚硅氧烷的固化产物。
本发明仍进一步涉及层压的基底,它包括:
第一基底;
覆在第一基底上的至少一个额外的基底;和
在每一基底的至少一个表面的至少一部分上的硅氧烷粘合剂涂层,条件是至少一部分粘合剂涂层在相邻基底的相对表面之间且与之直接接触,其中该粘合剂涂层包括至少一种具有上式(I)的有机基氢聚硅氧烷的固化产物。
本发明的硅氧烷粘合剂具有高的透明度且对各种基底具有优良的粘合性。而且,硅氧烷粘合剂在暴露于比粘合剂的分解温度高的温度下之中和之后具有高的粘合性、低的可燃性(这通过低的热量释放速度来佐证)和高的焦炭产率。
本发明的硅氧烷粘合剂可用于要求在升高的温度下具有高的粘合性,低的可燃性和高的透明度的粘合剂的应用中。例如,在制造防火窗和玻璃防火墙中,该粘合剂可用于粘结玻璃板。
参考下述说明、所附权利要求书和附图,本发明的这些和其他特征,以及优点将变得显而易见。

本发明的硅氧烷粘合剂具有高的透明度,和对各种基底具有优良的粘合性。而且,所述硅氧烷粘合剂在暴露于比粘合剂的分解温度高的温度之中和之后具有高的粘合性,低的可燃性(这通过低的热量释放速度来佐证)和高的焦炭产率。
本发明的硅氧烷粘合剂可用于要求在升高的温度下具有高的粘合性,低的可燃性和高的透明度的粘合剂的应用中。例如,在制造防火窗和玻璃防火墙中,该粘合剂可用于粘结玻璃板。
