Emulsion-Type Adhesive (37% Resin Solids) |
| 配方组成： |
In the adhesive field, as in the case of many other industries, the
latex or emulsion adhesive that can be thinned with water is rapidly
gaining wide-spread recognition. The majority of these compounds are
based on high molecular weight resins that have been polymerized in a
water medium. Here, too, "Neville" Resins can be used to great
advantage. Their inherent tackiness improves the initial adhesion and
also aids in prolonging the tack life of the adhesive film. Their trial
is strongly recommended to those who are actively engaged in or planning
on producting latex adhesives.
It is necessary that the highly hydrophobic "Neville" resins be
emulsified or made water miscible so that they need only be stirred
into the latex adhesive. The following emulsification information is
given to this end.
If a hydrocarbon solvent, such as toluene, mineral spirits, etc., can be
tolerated in the adhesive formulation, then the emulsification of the

The resin is initially powdered by ball milling or any other conventional means. A slurry is made of the above and passed through a colloid mill at 7200 r.p.m. (Premier Mill, 3.5 in. pulley). Multiple passes are made reducing the mill setting from 0.010 in. to 0.002 in. |
