The invention belongs to the technical field of
emulsion, and relates to an environment-friendly water-based glue special for an inner core of a fireproof door and a preparation method of the environment-friendly water-based glue special for the inner core of the fireproof door. 5 to 10 parts of deionized water; 0.15 to 0.3 part of a defoaming agent; 0.1 to 0.5 part of a pH
regulator; 0.2 to 0.7 part of a
thickening agent; 1.5-2 parts of a coalescing agent; 0.5-1 part of a dispersant; 30-40 parts of heavy
calcium powder; and 10-15 parts of talcum
powder. The preparation method comprises the following steps: firstly, adding the polyacrylate
polymer and the deionized water into a reaction kettle, stirring, controlling the stirring speed to be 300-500r / min until the mixture is uniform, then sequentially adding the pH
regulator, the coalescing agent, the dispersing agent and the defoaming agent, continuously stirring for 15-20 minutes, then adding the heavy
calcium carbonate and the talcum
powder, simultaneously adjusting the rotating speed to be 600-900r / min, uniformly mixing, then adding the dispersing agent and the defoaming agent, continuously stirring for 15-20 minutes, and uniformly mixing to obtain a finished product. And adding the
thickening agent according to a small-amount and multi-time principle until the
viscosity is qualified to obtain a finished product. The product disclosed by the invention has the advantages of extremely low VOC (Volatile Organic Compounds), no
combustion or explosion, small
odor, convenience in construction and the like, can be comparable with a double-component product in the aspects of paint film
hardness, cohesiveness and the like, and is short in
curing time and low in cost.
