[Means for solution]
A dental curable composition has a curing time of 30 seconds to 120 minutes and includes a compound having an acidic group in the molecule (A), a polymerizable monomer (B), an organic amine compound (C) and a sulfur-containing reducing compound (D). In the dental curable composition, the content of the component (A) is 0.01 to 80 parts by weight, the content of the component (B) is 21 to 99.8 parts by weight, the content of the component (C) is 0.01 to 30 parts by weight and the content of the component (D) is 0 to 30 parts by weight (the total of the components (A) to (D) is 100 parts by weight. When any of the compounds belongs to a plurality of the components (A) to (D), the parts by weight of the compound is divided by the number of the components to which the compound belongs, and the quotient is used as the content of each component).
[Advantage]
The composition may be cured at a relatively low temperature close to the body temperature without using a peroxide-based polymerization initiator, and has good sealing property and adhesion.
[解决方法]
一种牙科固化组合物的固化时间为30秒至120分钟,包括分子中含有酸性基团的化合物(A)、可聚合单体(B)、有机胺化合物(C)和含
硫还原化合物(D)。在牙科固化组合物中,组分(A)的含量为 0.01 至 80 份(按重量计),组分(B)的含量为 21 至 99.8 份(按重量计),组分(C)的含量为 0.01 至 30 份(按重量计),组分(D)的含量为 0 至 30 份(按重量计)(组分(A)至(D)的总和为 100 份(按重量计))。当任何一种化合物属于多种组分(A)至(D)时,该化合物的重量份数除以该化合物所属组分的数量,所得之商作为各组分的含量)。
优势
该组合物可在接近人体温度的相对低温下固化,无需使用过氧化物基聚合
引发剂,并具有良好的密封性和粘合性。
