Abstract

The invention belongs to the technical field of adhesives, and discloses a rapidly-viscose self-dry emulsion adhesive, and a preparation method and an application thereof. The adhesive comprises an acrylate emulsion, an aqueous polychloroprene emulsion, deionized water, hydrophilic fumed nano-silica, pH regulators, an aqueous wetting dispersant, a zinc oxide dispersion, an antifoaming agent, a sterilizing antiseptic and an antioxidant; the acrylate emulsion and the aqueous polychloroprene emulsion are main body resin emulsions; and the pH regulators comprise a pH regulator of the acrylate emulsion and a pH regulator of the aqueous polychloroprene emulsion. The rapidly-viscose self-dry emulsion adhesive has the advantages of good stability, good instantaneous bonding effect, fast initial adhesion, long open time, excellent heat resistance and excellent water resistance, and is used for material bonding and household article bonding.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and relates to an emulsion adhesive, in particular to a quick-adhesive self-drying emulsion adhesive and its preparation method and application. Background technique [0002] The low-viscosity water-based adhesives for upholstered furniture such as sofas, mattresses, and pillows currently on the market mainly include: water-based neoprene adhesives and water-based polyurethane adhesives, etc. Among them, the adhesives for water-based polyurethane upholstered furniture need to be activated by heating It can only be used, which does not meet the cold bonding conditions of the adhesive in this industry. In addition, the two-component polyurethane adhesive is inconvenient to use, and there are special requirements for equipment, which restrict its wide use. Water-based chloroprene system adhesives are widely used due to their advantages of environmental protection, non-toxicity, tasteless, and good...
