Detailed Description
In order to explain the technical contents and structural features of the present invention in detail, the following description is given with reference to the embodiments.
The water-based wallpaper adhesive comprises, by weight, 50-60 parts of modified styrene-acrylic emulsion, 30-40 parts of water-based neoprene latex, 10-20 parts of rosin emulsion, 1-5 parts of water-based cross-linking agent and 1-2 parts of pH regulator. Wherein the modified styrene-acrylic emulsion, the water-based neoprene latex and the rosin emulsion are all ionized emulsions, and the particle size is less than or equal to 0.5 micron.
Preferably, the modified styrene-acrylic emulsion is prepared by modifying styrene-acrylic emulsion with epoxy resin. The styrene-acrylic emulsion modified by the epoxy resin can interact with the waterborne neoprene latex and the rosin emulsion, so that the water resistance of the waterborne wallpaper adhesive and the adhesive force of the waterborne wallpaper adhesive to a wall surface and a wallpaper are obviously improved, and the adhesive force and the water resistance are obviously improved compared with the styrene-acrylic emulsion which is not modified by the epoxy resin.
Preferably, the rosin emulsion is a modified terpene phenolic resin. The modified terpene phenolic resin, the modified styrene-acrylic emulsion and the water-based neoprene latex are added to react with each other under the action of the water-based cross-linking agent, so that the flexibility and the ductility of the water-based wallpaper adhesive can be improved, and the sticking time of the water-based wallpaper adhesive can be prolonged. The water-based wallpaper adhesive usually needs to spend several hours or more for pasting wallpaper, so that the adhesive time of the water-based wallpaper adhesive is prolonged to ensure that the water-based wallpaper adhesive has enough time for construction operation, the adhesive quality of the wallpaper is ensured, and the wallpaper is not easy to be adhered due to the fact that the best adhesive effect time is easily missed because the adhesive time is short.
The modified terpene phenolic resin is prepared by modifying terpene phenolic resin with an organic silicon modifier. The terpene phenolic resin and the organic silicon modifier are blended to react with the organic silicon modifier during curing of the terpene phenolic resin, so that the crosslinking degree of the terpene phenolic resin after curing can be increased, and the heat resistance and the toughness of the terpene phenolic resin can be improved.
Preferably, the aqueous crosslinking agent is a modified isocyanate crosslinking agent. The modified isocyanate crosslinking agent promotes the crosslinking action among the water-based neoprene latex, the rosin emulsion and the modified styrene-acrylic emulsion, can improve the interaction force among all components of the water-based wallpaper adhesive, and increases the binding force, thereby enhancing the scratch resistance, the seepage resistance and the water resistance, preventing the water-based wallpaper adhesive from yellowing and resisting hydrolysis, and solving the problem of yellowing of wallpaper caused by poor performance of the wallpaper adhesive.
Preferably, the modified isocyanate crosslinking agent is prepared by modifying isocyanate with aziridine, and mainly depends on the ring-opening reaction of aziridine, and NCO groups generated by non-deblocking reaction.
Preferably, the pH adjusting agent is AMP-95. AMP-95 is a multifunctional amine assistant, which can stabilize the pH value of the water-based wallpaper adhesive, improve the storage stability of the water-based wallpaper adhesive and simultaneously improve the water resistance of the water-based wallpaper adhesive.
Preferably, 5-10 parts of poly alpha-methyl styrene emulsion is also included. The poly alpha-methyl styrene emulsion, the neoprene latex and the modified styrene-acrylic emulsion interact with each other, so that the initial adhesion strength of the water-based wallpaper adhesive can be improved, the water-based wallpaper adhesive is prevented from falling off, and the wallpaper pasting is facilitated.
A preparation method of water-based wallpaper adhesive comprises the following steps:
a, weighing modified styrene-acrylic emulsion, water-based neoprene latex, rosin emulsion, water-based cross-linking agent, poly alpha-methyl styrene emulsion and pH regulator according to the proportion;
b, mixing and stirring the components weighed in the step a. Specifically, the stirring may be performed at 600 rpm for 120 minutes.
