Abstract

The invention discloses a waterborne fireproof coating material and a preparation method and a device thereof. The waterborne fireproof coating material comprises the following components in parts byweight: 65-75 parts of acrylic waterborne emulsions, 8-15 parts of organic solvents, 3-7 parts of wax emulsions, 8-12 parts of auxiliaries, 0.5-1 part of graphene oxide, 8-13 parts of fillers, 2-4 parts of organic silicon resins, 3-5 parts of dispersants, 120-200 parts of water and 16-25 parts of titanium dioxide. According to the waterborne fireproof coating material, additives with adverse effects on human body and environment such as a feeling agent, a flatting agent, an anti-scratch agent and a dispersant can be greatly reduced or saved, the excellent quality of the produced coating material is improved, and stable existence of other components in a filler mesh combining montmorillonite, glass powder and barium sulfate is guaranteed; the graphene oxide strengthens uniformity and stability of the filler mesh, so that the produced waterborne fireproof coating material can be more stable, more excellent in performance and more stable in overall performance; and meanwhile, the preparation method of the waterborne fireproof coating material is simple, a dispersing plate of a dispersion machine can efficiently and uniformly blend the slurry material, the shearing effect is good, andthe dispersing effect is excellent.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based fireproof coating and a preparation method and equipment thereof. Background technique [0002] Fire retardant coating is to brush the paint on the surface of those flammable materials, which can improve the fire resistance of the material, slow down the speed of flame spread, or prevent burning within a certain period of time. This type of coating is called fire retardant coating, or flame retardant coating. [0003] Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. Applied on the surface of flammable substrates to change the combustion characteristics of the material surface and retard the rapid spread of fire; or applied to building components to improve the fire...
