Abstract

The environment protecting multifunctional aqueous adhesive consists of two components. The component A consists of PVA, olefin unsaturated acid ester, olefin unsaturated anhydride or acid, emulsifier OP-10, sodium dodecyl benzene sulfate, ammonium peroxysulfate, sodium bicarbonate, dibutyl phthalate, defoaming agent and water. The component B consists of organic compound with one or more hydroxyl group, polyisocyanate and organic acid ester. When used, the two components are in-situ mixed together. The adhesive can be cured at normal temperature naturally in high speed. The present invention has the features of excellent water resisting performance, excellent antifreezing performance, strong adhesive force, high adhesion strength, no corrosion, etc.

Description

technical field [0001] The invention belongs to an adhesive in coatings, and is applied in the technical field of indoor and outdoor decoration bonding, in particular to an environmentally friendly multifunctional water-based polymer for bonding indoor and outdoor decoration, furniture manufacturing, wood processing and non-metallic materials. polymer adhesive. Background technique [0002] As we all know, with the continuous progress of society, people's living standards are also improving day by day. Beautifying the indoor and outdoor environment is a concrete manifestation of the improvement of living standards, especially in the field of interior decoration. At present, in the fields of interior decoration and furniture manufacturing, there are many kinds of glues. However, water-based 107 glue, urea-formaldehyde glue, white latex, etc. are widely used in the market. Most of them have low quality, poor bonding strength, and use Short life, high cost, and many hidden da...
