Problems solved by technology

[0002] The main types of adhesives are polyurethane, polysulfide, silicone, acrylic ester, styrene-butadiene rubber, butyl rubber, asphalt and oily caulk, etc. Among them, polyurethane adhesive has high strength, tear resistance, soft wear resistance , puncture resistance, oil resistance and medium corrosion resistance, and is widely used, but the polyurethane synthesized from natural raw materials is not resistant to mold erosion, and it is easy to breed bacteria when used in a humid and hot environment for a long time. With the multiplication and erosion of bacteria, the adhesive will appear Disadvantages such as blackening and yellowing may even destroy the performance of the adhesive, affect or even lose its bonding effect, and limit the application of polyurethane adhesives
