Abstract
Provided is a method for easily reinforcing a three-dimensional shaped object. The method for reinforcing a three-dimensional shaped object comprises reinforcing the three-dimensional shaped object using an impregnating composition containing a 2-cyanoacrylic acid ester having a specific structure, said impregnating composition having a viscosity at 25° C. in a range of from 1 to 1000 mPa·s, and said impregnating composition having a Shore hardness D in a range of from 20 to 75 when being hardened. Preferably, the three-dimensional shaped object is formed of an inorganic powder.
Claims19
A method for reinforcing a three-dimensional shaped object comprising (a) reinforcing the three-dimensional shaped object with an impregnating composition containing a 2-cyanoacrylic acid ester, in which the 2-cyanoacrylic acid ester is at least one selected from the group consisting of a compound represented by the following general formula (1) and the compound represented by the following general formula (2):
- wherein R1 represents a straight-chain or branched-chain alkyl group having from 3 to 12 carbon atoms, cycloalkyl group, allyl group, or aryl group;
- and
- wherein R2 represents an alkylene group having from 1 to 4 carbon atoms, and R3 represents a straight-chain or branched-chain alkyl group having from 1 to 8 carbon atoms,
- said impregnating composition having a viscosity at 25° C. in a range of from 1 to 1000 mPa·s and
- said impregnating composition having a Shore hardness D in a range of from 20 to 75 when being hardened.
A method for reinforcing a three-dimensional shaped object comprising
- (a) impregnating a composition containing a 2-cyanoacrylic acid ester into the three-dimensional shaped object;
- and
- (b) curing the impregnated composition,
- in which the 2-cyanoacrylic acid ester is at least one selected from the group consisting of a compound represented by the following formula (1) and a compound represented by the following formula (2):
- wherein R1 represents a straight-chain or branched-chain alkyl group having from 3 to 12 carbon atoms, cycloalkyl group, allyl group, or aryl group;
- and
- wherein R2 represents an alkylene group having from 1 to 4 carbon atoms, and R3 represents a straight-chain or branched-chain alkyl group having from 1 to 8 carbon atoms, said composition having a viscosity at 25° C. in a range of from 1 to 1000 mPa·s, and said composition having a Shore hardness D in a range of from 20 to 75 when being hardened.
