Problems solved by technology

[0002] Sealants are mainly used for smooth surfaces that need to be connected, such as bathrooms, sinks, kitchens, windows, etc., but the sealants will be in hot and humid conditions for a long time. The existing sealants contain resins and plasticizers, which can provide sufficient nutrients for microorganisms. Therefore, it is easy to be infected by microorganisms. In actual use, usually within half a year, there will be indelible mildew, mildew, discoloration, loss of waterproof performance and viscosity drop, etc., and even cause indoor environment pollution.

Abstract

The invention discloses a sealant mildew preventive, which comprises the following components by weight: 80-95 parts of a solvent and 5-20 parts of an effective mildew preventive component. The invention further provides a preparation method of the sealant mildew preventive. The sealant mildew preventive has the advantages of simple ingredients, easy manufacturing, small influence on the comprehensive performance of the sealant, like surface drying time, sag, tensile modulus, elastic recovery rate, yellowing time, surface smoothness after curing, difficult occurrence of mildew spots, mildew, color change, loss of waterproof performance, viscosity reduction and the like, and lasting mildew-proof effect, the action time can reach 3-5 years, the service life of the product is prolonged, and social resources are saved.

Description

technical field [0001] The invention relates to the technical field of adding additives, in particular to a sealant antifungal agent and a preparation method thereof. Background technique [0002] Sealants are mainly used for smooth surfaces that need to be connected, such as bathrooms, sinks, kitchens, windows, etc., but the sealants will be in hot and humid conditions for a long time. The existing sealants contain resins and plasticizers, which can provide sufficient nutrients for microorganisms. Therefore, it is easy to be infected by microorganisms. In actual use, usually within half a year, there will be indelible mildew, mildew, discoloration, loss of waterproof performance and viscosity drop, etc., and even cause indoor environment pollution. . Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention discloses a sealant antifungal agent, which comprises the following components in parts by weight: 80-95 parts of solvent and 5-20...
