Title: Alga-proofing and mildew-proofing agent for cement
Inventor: SHIGERU KEIJIRO
IPC: C04B22/06
Filed: 1992-12-28
Abstract: PURPOSE:To obtain an alga-proofing and mildew-proofing agent able to be added to uncured cement and concrete without inhibiting the curing reaction of cement, exhibiting excellent algaproofing and mildew-proofing property and causing little color change by mixing cuprous oxide powder with titanium oxide powder. CONSTITUTION:This alga-proofing and mildew-proofing agent for cement is composed of a mixture of cuprous oxide (Cu2O) powder and titanium oxide (TiO2) powder. Since cuprous oxide powder is insoluble in water in itself, it does not release copper ion having inhibitory action on the curing of cement. According to the progress of the curing of the cement, the cuprous oxide powder reacts with the formed calcium hydroxide to release copper ion and exhibits alga-proofing and mildew-proofing property after curing the cement. Furthermore, the alga-proofing and mildew-proofing property is increased because the titanium oxide acts as a catalyst in the reaction of calcium hydroxide with cuprous oxide to promote the release of copper ion.
