Abstract
Provided is a curable composition which forms a cured product that has excellent fireproof performance, while having excellent shape retainability even in cases where the expansion ratio of the cured product after firing is set to a high value. This curable composition includes a shape retention agent, while having fluidity when applied; and if a cured product that is obtained by curing this curable composition is fired in 600° C. air atmosphere for 30 minutes, the cured product after firing has shape retainability.
Claims9
1:
- A fireproof curable composition comprising a shape retention agent and having fluidity when applied,
- wherein, when a cured product after curing of the fireproof curable composition is fired in 600° C. air atmosphere for 30 minutes, the cured product after firing has shape retainability.
2:
- The fireproof curable composition according to claim 1,
- wherein the shape retention agent is at least one compound selected from the group consisting of a novolac-type epoxy resin, a phosphorus compound, a boron compound, and a benzoxazine compound.
3:
- The fireproof curable composition according to claim 1, comprising:
- (A) a (meth)acrylic acid ester polymer containing at least one crosslinkable silicon group in one molecule, and
- (B) a thermally expandable graphite.
4:
- The fireproof curable composition according to claim 1, further comprising:
- (C) an organic polymer including at least one crosslinkable silicon group in one molecule, the organic polymer being different from (A) the (meth)acrylic acid ester polymer including at least one crosslinkable silicon group in one molecule.
5:
- A cured product of the fireproof curable composition described in claim 1.
6:
- A fireproof material having fluidity when applied and comprising a cured product of a curable composition including a shape retention agent, wherein, when the cured product is fired in 600° C. air atmosphere for 30 minutes, the cured product after firing has shape retainability.
7:
- The fireproof material according to claim 6, wherein the shape retention agent is at least one compound selected from the group consisting of a novolac-type epoxy resin, a phosphorus compound, a boron compound, and a benzoxazine compound.
8:
- A method of constructing a fireproof structure, the method comprising:
- applying a curable composition that has fluidity when applied and comprises a shape retention agent, onto at least a portion of a surface of a construction, and
- curing the curable composition to form a cured product;
- wherein, when the cured product is fired in 600° C. air atmosphere for 30 minutes, the cured product after firing has shape retainability.
