Problems solved by technology

At present, most of the research on glass glue anti-mold is concentrated in the fields of aircraft, ships, electronics, machinery, etc., but it is easy to breed mold when used in water conservancy projects, water delivery projects, sewage treatment projects, etc., or long-term application in hot and humid environments. There are few reports on anti-mildew glass glue products that require extremely high sealing effects
If the glass glue used in these fields does not have anti-mold function, it is easy to breed mold, and the growth and spread of mold will erode the internal molecular structure of the glass glue, resulting in degradation and deterioration, affecting or even losing the sealing effect

Description

technical field [0001] The invention relates to the technical field of sealing materials, in particular to a high-strength water-resistant and mildew-proof glass glue. Background technique [0002] Glass glue is a common name for glass adhesive, and it is a multi-purpose functional material with both bonding and sealing properties. It can not only prevent internal gas or liquid leakage, but also prevent external dust, moisture, water, dirt and chemicals from intruding, and can prevent mechanical vibration, impact damage or achieve the effect of sound insulation and heat insulation. Glass glue can deform with the shape of the sealing surface, is not easy to flow and has certain adhesiveness, and is widely used in the sealing of parts in civil engineering, electronic appliances, mechanical equipment, transportation appliances and other fields. Glass glue is an indispensable and important material for solving running, popping, dripping and leaking, and plays an important role ...
