Embodiment

[0411] Hereinafter, although this invention is demonstrated based on an Example, this invention is not limited to an Example.

[0412] The raw materials used for the manufacture of each radically polymerizable resin composition (hereinafter, also referred to as "resin composition") in Examples 1 to 11 and Comparative Examples 1 to 3 are as follows.

[0413]

[0414] ·Metal soap (A1-1)

[0415] Cobalt octanoate (manufactured by Toei Chemical Co., Ltd., cobalt hexanoate, content of cobalt in the total product 8% by mass, molecular weight 345.34)

[0416] ·Metal soap (A1-2)

[0417] Manganese octoate (manufactured by Toei Chemical Co., Ltd., manganese caproate, content of manganese in the total product 8% by mass, molecular weight 341.35)

[0418]

[0419] In addition, "monofunctional" in the following thiol compounds means that the number of mercapto groups in the molecule is one, and each numerical value of "bifunctional", "trifunctional", and "tetrafunctional" means that...

Synthetic example 1

[0453] Synthesis example 1: Synthesis of thiol-modified polycarbonate diol (B1-2)

[0454] 500 g (500 mmol) of C-1090 (manufactured by Kuraray Co., Ltd., molecular weight: 1,000, diol components: 3-methyl-1,5-pentanediol and 1,6-hexanediol) as a polycarbonate polyol, 3 -144 g (1198 mmol) of mercaptobutyric acid (manufactured by Showa Denko Co., Ltd.), 19 g (99.8 mmol) of p-toluenesulfonic acid monohydrate (manufactured by Tokyo Chemical Industry Co., Ltd.), and 500 g of toluene (manufactured by Junsei Chemical Co., Ltd.) were added to a 2L flask , install the Dean-Stark apparatus and cooling tubes.

[0455] After reducing the pressure in the reaction system to 73.3 kPa (550 mmHg), it heated using a 120 degreeC oil bath, stirring the content. After stirring for 7 hours, it was left to cool to room temperature, and the reaction liquid was neutralized with a 5% by mass aqueous sodium bicarbonate solution. The organic layer was further washed three times with ion-exchanged water...

Abstract

A radical-polymerizable resin composition which comprises one or more metal-containing compounds (A) selected from among metal soaps (A1) and metal complexes (A2) having a beta-diketone skeleton, oneor more thiol compounds (B) selected from among secondary thiol compounds (B1) and tertiary thiol compounds (B2), a radical-polymerizable compound (C), and an elastomer (D), and which can be stably cured not only under dry conditions but also in water or seawater or on wet bases, that is, stably cured on dry surfaces, on surfaces immersed in water or seawater, or on wet surfaces; a prepreg sheet obtained by prepolymerizing the radical-polymerizable resin composition; a curable material for preventing concrete flaking which comprises the radical-polymerizable resin composition; a primer; a radical-polymerizable coating composition; and a material for restoring inorganic structures.

Description

technical field [0001] The present invention relates to free radical curing even under dry conditions, in water and seawater, and on wet substrates, i.e. on dry surfaces, on surfaces in water and seawater, and on wet surfaces, and A radically polymerizable resin composition that can follow the expansion and shrinkage of a substrate according to seasonal and diurnal temperature changes, and uses of the radically polymerizable resin composition. Background technique [0002] Metallic soaps have good solubility in resins and solvents. In addition, they have various functions. They are used as curing accelerators for unsaturated polyester resins, desiccants for coatings and printing inks, adhesives for rubber and tires, and lubricants. It is widely used as oil extreme pressure agent, combustion aid, and polymerization catalyst. [0003] However, when a metal soap is used as a curing accelerator in the presence of water, there is a problem that its function is not sufficiently e...
