Problems solved by technology

With the development of society, people have put forward higher requirements for the performance of polyurethane potting adhesives. The antibacterial properties of existing polyurethane potting adhesives can no longer meet the requirements of society and need to be improved. In addition, the burning speed of polyurethane is fast, And toxic gas will be produced during the combustion process, which causes most of the existing polyurethane potting adhesives to have poor flame retardancy during use, which limits the application of polyurethane potting adhesives

Description

technical field [0001] The invention relates to the technical field of potting glue, in particular to an antibacterial and flame-retardant polyurethane potting glue. Background technique [0002] Potting glue is mainly used for the bonding of electronic components in electronic equipment. It is also called electronic glue. It is liquid before it is cured and has fluidity. After curing, it can play waterproof, moisture-proof, dust-proof, insulation and heat conduction. , Confidentiality, anti-corrosion, temperature resistance, shock resistance, can be used for bonding, sealing, potting and coating protection of electronic components. At present, the most used ones are mainly epoxy resin potting glue, silicone resin potting glue and polyurethane potting glue. [0003] Polyurethane can have high elasticity and strength in a wide range of hardness. In addition, it has excellent wear resistance, oil resistance, fatigue resistance, vibration resistance, water resistance, electric...
