Technical Field

The invention relates to the technical field of adhesives, in particular to an adhesive for bonding glass and ABS plastic.

Background

With the successive proposition of various adhesion theories in the middle of the 20 th century and the deep progress of basic research works such as adhesive chemistry, adhesive rheology, adhesive failure mechanism and the like, the performance, variety and application of the adhesive have been developed dramatically and rapidly.

The carpenter's board is in the bonding, because carpenter's board surface is not level and smooth, and a lot of slight places are unevenness state, and current carpenter glues and hardly accomplishes bonding these unevenness places in limited time, needs longer time's pressfitting just can accomplish, from the angle of volume production carpenter's board, current gluing agent bonding time overlength has seriously influenced the production progress.
