Polyurea hand, their preparation and use

The present invention provides a hand-polyurea, their preparation and use. Hand polyurea comprising the components of the present invention the following weight ratio General: A component: 20 to 70 parts of aromatic isocyanates; hindered amino compound 5-60 parts; 20-85 parts of a polyether polyol; propyl carbonate reactive diluent ester 1-5 parts; component B: 48-93 parts of a sterically hindered amino compound; 5-50 parts filler; auxiliary parts 2-4; 1-3 parts pigment; mass ratio of a component to B component is 2 : 1 to 1.5: 1. The present invention also discloses a method for preparing a hand-polyurea. Hand polyurea formulations of the present invention scientific, reasonable, its preparation method is simple, easy, manual present invention polyureas can ensure the mechanical properties, while prolonged gel time, thus achieving a narrow, complex environment manual brushing.
