Problems solved by technology

[0002] It is known in the water conservancy machinery manufacturing industry that in order to prolong the service life of hydraulic machinery components, the common method is to apply protective glue on the outside of ship parts and hydraulic machinery components. Traditional protective glue has poor water resistance and corrosion resistance and is easy to Hydrolysis, soaked in water for 2-3 months, it will fall off, and the service life is short. Therefore, it is necessary to take out the metal parts soaked in water in 2-3 months, and re-coat the glue, which is not only troublesome, but also has a high cost of use.

Abstract

The invention discloses an adhesive capable of being cured at normal temperature and particularly relates to a zirconium strength adhesive capable of being cured at normal temperature with waterproof and corrosion proof performances and a preparation method thereof. The adhesive is prepared by warming, stirring and reacting raw materials such as toluene diisocynate, polytetrafluorofuran polyether glycol, 3, 3'-dichloro-4, 4'-diaminodiphenylmethane, polypropylidene ether dihydric alcohol, diethyltoluenediamine and a diluent. The adhesive is not only long in service life, but also low in using cost. The adhesive is suitable for protecting metal parts such as hydraulic mechanical parts which are soaked in water for a long time.
