Mold-resistant construction materials
Mold-resistant construction materials distinguished by the presence therein of an azole alone or in combination with a sporulation inhibitor and/or with a substance which is antiadhesive with respect to microorganisms.
1. A material comprising a filter medium, construction material, construction auxiliary, textile, pelt, paper, hide or leather, and 0.1 to 1% by weight of at least one azole compound selected from one or more of propiconazole, tebuconazole, and their derivatives, 0.0001 to 0.05% by weight of at least one sporulation inhibitor selected from ortho-phenylphenol or an ortho-phenylphenol-silicic ester, and 0.001 to 10% by weight of at least one antiadhesive substance comprising a silicic ester of a C 8 to C 22 fatty alcohol adduct with 3 to 15 units of ethylene oxide; wherein the azole compound, the sporulation inhibitor and the antiadhesive substance are present in amounts that achieve a synergistic effect against mold.
2. The material of claim 1 , wherein the sporulation inhibitor is ortho-phenylphenol.
3. The material of claim 1 , comprising 0.01% to 2% by weight of the antiadhesive substance.
4. The material of claim 1 , comprising 0.2% to 0.6% by weight of the azole compound, 0.001% to 0.05% by weight of the sporulation inhibitor, and 0.05% to 1.0% by weight of the antiadhesive substance.
5. The material of claim 1 , wherein the azole:sporulation inhibitor ratio is in the range of 1:0.0001 to 1:0.5.
6. A method of inhibiting mold-related discoloration, comprising the steps of providing a material selected from the group consisting of construction materials, construction auxiliaries, filter media, textiles, pelts, paper, hides, and leather, and providing said material with an azole compound selected from one or more of propiconazole, tebuconazole, and their derivatives in an amount of about 0.1 to 1% by weight, a sporulation inhibitor selected from ortho-phenylphenol or an ortho-phenylphenol-silicic ester in an amount of about 0.0001 to 0.05% by weight, and an antiadhesive substance comprising a silicic ester of a C 8 to C 22 fatty alcohol adduct with 3 to 15 units of ethylene oxide in an amount of about 0.001 to 10% by weight, wherein said amounts are synergistically effective to inhibit mold-related discoloration of said material.
7. The method of claim 6 , wherein the construction material or construction auxiliary is selected from the group consisting of bonders, sealants, fillers, coatings, adhesives, plastic, varnish, paint, render, mortar, screed, concrete insulation, and primers.
8. The method of claim 6 , wherein the material is provided with 0.1% to 1% by weight of the azole compound, 0.0001% to 0.05% by weight of the sporulation inhibitor, and 0.01% to 2% by weight of the antiadhesive substance.
