EXTERNAL-WALL FIRE RETARDANT COATING WITHOUT MOULD-INHIBITING ANTISEPTIC AGENT ADDED THERETO, AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/135721
Kind Code:
A1
Abstract:
Disclosed are an external-wall fire retardant coating without a mould-inhibiting antiseptic agent added thereto, and a preparation method therefor. The fire retardant coating comprises potassium silicate, ethylene glycol, 800 mesh heavy calcium carbonate, 700 mesh heavy calcium carbonate, calcined kaolin, 1250 mesh talcum powder, bentonite, diatomite, hydroxyethyl cellulose and a sodium polycarboxylate-salt-type dispersant. The preparation method involves adding the bentonite, hydroxyethyl cellulose and sodium polycarboxylate salt type dispersant at 350-550 r/min; and adding the 800 mesh heavy calcium carbonate, 700 mesh heavy calcium carbonate, diatomite, calcined kaolin, and 1250 mesh talcum powder at 800-1000 r/min, and adding an emulsion, ethylene glycol and potassium silicate at 1000-1200 r/min. By adding the potassium silicate to adjust the pH of the coating, an external-wall fire retardant coating inhibiting the growth and propagation of microorganisms such as bacteria and fungi can be achieved, without adding a mould-inhibiting antiseptic agent.
