Abstract
The present invention discloses a high-adhesion aqueous polyurethane adhesive comprising the following components by weight: 40 to 50 parts of polyester diol, 20 to 30 parts of isophorone diisocyanate, 5 to 15 parts of a polyol, 3 to 5 parts of a curing agent, 1 to 3 parts of dibutyl tin dilaurate, 5 to 10 parts of triethylamine, 3 to 8 parts of a chain extender and 10 to 20 parts of tackifying resin emulsion. Through use of the polyol and the tackifier resin emulsion, the curing time at room temperature of the high-adhesion aqueous polyurethane adhesive is effectively shortened, the adhesion property is significantly improved, and the market prospect is broad.
Description
Technical field
The present invention relates to sizing agent field, particularly relate to a kind of high-adhesion Aqueous Polyurethane Adhesives.
Background technology
Aqueous Polyurethane Adhesives, because having pollution-free, the feature such as transportation safety, good work environment, will become the main flow in sizing agent market gradually.But aqueous polyurethane (WPU) sizing agent exists the shortcomings such as the little and poor water resistance of slow, the first viscous force of rate of drying, especially cohesive strength is low has had a strong impact on its application.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of high-adhesion Aqueous Polyurethane Adhesives, can solve the above-mentioned shortcoming that Aqueous Polyurethane Adhesives exists.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of high-adhesion Aqueous Polyurethane Adhesives, comprise following parts by weight of component: polyester diol 40 ~ 50 parts, isoflurane chalcone diisocyanate 20 ~ 30 parts, polyol 5 ~ 15 parts, 3 ~ 5 parts, solidifying agent, dibutyl tin laurate 1 ~ 3 part, triethylamine 5 ~ 10 parts, chainextender 3 ~ 8 parts, tackifier resin emulsion 10 ~ 20 parts.
In a preferred embodiment of the present invention, described tackifier resin emulsion is that aqueous tackifier Gum Rosin emulsion or many carbon strengthen resin emulsion.
