Because carbon fiber powder is not soluble in water, latex is influenceed in order to prevent carbon fiber powder from being sunk in storage and transportation poly- The heat insulation effect of paint, dispersant include odium stearate, neopelex, dodecyl phenol polyethenoxy ether, stearic acid At least two in triethanolamine, cetyl ammonium phosphate, when being carried out compounding use, carbon fiber powder can be dramatically increased Dispersiveness, strengthen the stability of emulsion paint, extend the holding time.
Embodiments described above is part of the embodiment of the present invention, rather than whole embodiments.The reality of the present invention The detailed description for applying example is not intended to limit the scope of claimed invention, but is merely representative of the selected implementation of the present invention Example.Based on the embodiment in the present invention, what those of ordinary skill in the art were obtained under the premise of creative work is not made Every other embodiment, belongs to the scope of protection of the invention.
