Abstract

The invention provides a method for preparing an antibacterial epoxy resin pouring sealant. The method comprises the following steps: 1) drying ginkgo leaves, crushing the ginkgo leaves and sieving to obtain the ginkgo leaves powder, adding an ethyl alcohol solution, performing ultrasonic extraction, standing and filtering the material, concentrating the material to obtain a ginkgo leaves extract product; 2) adding diatomite and the ginkgo leaves extract product in a mixer, heating the materials and performing magnetic stirring, taking the product out and drying the product, grinding the product and sieving the product to obtain a composite antiseptic; 3) preparing a mixed liquor by the composite antiseptic, heating the mixed liquor, adding an aluminic acid ester coupling agent, stirring the materials, performing pumping filtration, drying the materials to obtain the modified composite antiseptic; 4) adding epoxy resin, a flexibilizer, a diluents, a filling material and the modified composite antiseptic in a stirred tank for stirring the above materials, performing vacuum defoaming to obtain a component A; 5) adding a curing agent and a promoter in the stirred tank for stirring the above materials, performing vacuum defoaming to obtain a component B; and 6) uniformly mixing the component A and the component B to obtain the antibacterial epoxy resin pouring sealant. The prepared antibacterial epoxy resin pouring sealant has good antibacterial property.

Description

Technical field: [0001] The invention relates to a potting glue, in particular to a preparation method of an antibacterial epoxy resin potting glue. Background technique: [0002] Epoxy resin potting glue refers to a type of epoxy resin liquid packaging or potting material made of epoxy resin as the main component, adding various functional additives, and matching with a suitable curing agent. According to its different composition, it is mainly divided into two types, one is a one-component epoxy potting glue; the other is a two-component epoxy potting glue. According to the color, it can be divided into transparent, black and milky white, etc. According to the mixing ratio, there are generally 1:1, 2:1, 3:1 and black 4:1 or 5:1. [0003] One-component epoxy potting glue is a kind of medium-temperature or high-temperature-curing variety formulated with latent epoxy curing agent. Its curing conditions often need to be heated to cure, and its storage conditions are generally...
