Problems solved by technology

However, ordinary polyurethane materials are easy to hydrolyze and have poor antibacterial properties. In the process of use, there are defects such as water resistance, poor surface performance, and easy to be destroyed by bacteria, which greatly limits the practical application of polyurethane glass glue.

Description

Technical field [0001] The invention relates to the technical field of glass glue, in particular to an antibacterial, water-resistant and aging-resistant polyurethane glass glue. Background technique [0002] Glass glue is a material used to fill gaps and fill the interface of the base layer. It mainly includes silicone (including modified silicone), polyurethane, polysulfide rubber, acrylic, SBR rubber, butadiene rubber Base rubber, asphalt, oily caulking glue, etc. Polyurethane glass glue has excellent wear resistance, low temperature flexibility, wide range of performance adjustments, large mechanical strength, good adhesion, good elasticity, excellent oil resistance, biological aging resistance, and moderate price. It has been widely used. It is used in many industries such as furniture industry, construction industry and transportation industry. However, ordinary polyurethane materials are easily hydrolyzed and have poor antibacterial properties. During use, there are defe...
