Abstract

The invention discloses anti-mildew and antibacterial glass cement, comprising a nano inorganic antibacterial agent, hydroxy silicone, methyl silicone, methylsilane, fumed silica, calcium carbonate superfine powder, dibutyltin dilaurate and amino silane. The invention also discloses a preparation method of the glass cement. The glass cement disclosed by the invention can be used at a high temperature, high humidity and a very low temperature (200 DEG C below zero), has strong adhesive strength and durable flexibility, has good anti-mildew and antibacterial performances due to adding of an efficient non-toxic and environment-friendly mould inhibitor, and especially has a good antibacterial effect on escherichia coli and staphylococcus aureus.

Description

technical field [0001] The invention belongs to the field of adhesives, and in particular relates to a mold-proof and antibacterial glass glue and a preparation method thereof. Background technique [0002] Glass glue is a material for bonding glass to glass or glass to other substrates. The types of glass glue on the market include acid glass glue, neutral weather-resistant glass glue, silicic acid neutral glass structural glue, silicone stone glue, medium Anti-mildew glass glue, hollow glass glue, special glue for aluminum-plastic panels, special glue for aquariums, special glue for large glass, special glue for bathroom mildew-proof, acidic structural glue, etc. However, because most of the glass glue is used in a relatively humid environment, there are many bacteria, and it is very easy to mold. Contents of the invention [0003] In order to overcome the above-mentioned technical defects, the invention discloses a glass glue with good performance, remarkable anti-mild...
