Problems solved by technology

[0006] Although Japanese Patent Laid-Open No. 9-110913 proposes adding an aprotic solvent to tributylboron or partially tributylboron oxide, or further adding an inert liquid or solid organic oligomer or polymer to improve safety, However, when a large amount of additives are added, the activity of the polymerization initiator tends to decrease, and sometimes the viscosity of the initiator composition increases due to the addition of organic oligomers or polymers, making it difficult to use an accurate amount.

Embodiment 1～6 and comparative example 1～12

[0091] (1) Preparation of polymerization initiator composition

[0092] In a nitrogen box, a prescribed amount of TBB·O (where only Comparative Example 2 is TBB) and a solvent having the composition shown in Table 1 were added to a stoppered Erlenmeyer flask with a Teflon stirrer, and stirred for 10 hours. The obtained polymerization initiator composition was filled in a syringe having a capacity of 1 ml and a needle inner diameter of 0.3 mm in a nitrogen atmosphere.

[0093] (2) Performance of the polymerization initiator composition

[0094] Various tests of Examples 1-6 and Comparative Examples 1-12 were implemented with the composition shown in Table 1. The results are shown in Table 1. In addition, various tests were performed as follows.

[0095] Fire test:

[0096] At 23°C±2°C, drop 0.5ml of the polymerization initiator composition on the filter paper (whatman, No.3) (test 1) or drop 5 drops (about 0.03g) of the polymerization initiator composition on the 8-layer O...

Embodiment 7

[0111] (1) Under water injection, cut the labial side of the bovine front teeth to take out the dentin surface, and grind it with No. 600 emery paper to form an adhesive surface. After drying the bonding surface, treat it with an etching solution containing 10% by weight of citric acid and 3% ferric chloride for 10 seconds, wash it with water for 10 seconds, and dry it with air for 15 seconds. Paste on the bonding surface to limit the bonding area.

[0112] (2) Get 4 drops of polymerizable monomers (0.09g) containing MMA / 4-META=95 / 5 (weight ratio), 1 drop of the polymerization initiator composition (0.007g) of embodiment 3 in Danping dish, Add 0.07g of p-MMA and 0.07g of ZrO 2 Microparticles (average particle diameter about 5 μm, obtained by surface coating with about 3% by weight of PMMA) were lightly mixed for 10 seconds to prepare a resin paste.

[0113] (3) The resin paste was applied to the adhesive surface prepared in (1), and an acrylic rod was adhered to prepare a sa...

Abstract

A polymerization initiator composition which does not burn or ignite even when it contacts paper or the like in air and can provide high polymerization activity to a polymerizable composition to cure it in a short period of time, and an adhesive composition comprising the same. The above polymerization initiator composition comprises 100 parts by weight of (A) an organic boron compound such as a trialkyl boron, alkoxyalkyl boron, dialkyl borane, monocyclo or bicyclo compound having a boron atom as a hetero atom or partially oxidated trialkyl boron, 5 to 40 parts by weight of (B) an aprotic solvent having a boiling point of 50 to 120 DEG C, and 0.2 to 5 parts by weight of (C) an alcohol having a boiling point of 60 to 180 DEG C.

Description

technical field [0001] The present invention relates to a dental or surgical adhesive composition and a polymerization initiator composition for the adhesive. In more detail, it relates to a dental or surgical adhesive composition having high curing performance and adhesive performance, and a polymerization initiator used for the adhesive and having improved safety against fire when attached to paper or the like. agent composition. Background technique [0002] Japanese Patent Publication No. Sho 51-37092 discloses a dental or surgical adhesive using a partial trialkyl boron oxide, which is a product obtained by reacting a trialkyl boron with 0.3 mol to 0.9 mol of oxygen, as a polymerization initiator. As described in Japanese Patent Publication No. 51-37092, since trialkyl boron is an extremely unstable substance in the air, it reacts rapidly with oxygen and catches fire when exposed to the air, so it is an extremely dangerous substance to handle. The invention of Japanes...
