Abstract
This is a new all-purpose adhesive and the way of making it. According to weight proportion, this mixture comprises vinyl acetate-acry (70-90 shares), acrylic nitrile or (and) acrylic acid and one of or more than one of its esters mixture (10-30 shares), azoic compound (0.1-2 shares), alcohols (100-200 shares). It is made in the reaction kettle attached with agitator tank, refluxing chiller, vacuum system and temperature meter, in the condition of 60-80 deg.C for 6-9 hours. The commoner used in making the mixture can be selected according to different adhesive materials, so the mixture has high adhesive, and it is widely adopted, conveniently used. It overcomes the disadvantages of the present adhesive agent in poor adhesive and narrow adaptation.
