Embodiment Construction

[0040] Below in conjunction with specific embodiment the technical scheme of invention is described in detail, the raw material of each embodiment and its content by weight percentage, main performance index are listed in following table 1, the preparation method of coating in each embodiment is as follows: following steps:

[0041] (1) Take the above-mentioned raw materials respectively by the ratio in Table 1;

[0042] (2) Mix the coupling agent with the inorganic film-forming substance, and let stand for 24h; mix the film-forming aid with the polymer emulsion film-former, and let stand for 24h;

[0043] (3) Add water, dispersant and non-expandable inorganic heat-insulating filler into the mixer, and stir evenly;

[0044] (4) Add the N-P cage-type macromolecular expansion flame retardant into the high-speed disperser, add the mixture obtained in step (3) and mix and stir, after high-speed dispersion, the dispersion speed is 1200r / m, and then place it In the nano-scale grind...

Abstract

The invention discloses an environment-friendly fireproof coating and a preparation method thereof, and relates to the field of building coatings. The environment-friendly fireproof coating is prepared from the following raw materials: a macromolecular emulsion film forming matter, an inorganic film forming matter, an intumescent organic flame retardant, a non-intumescent inorganic heat-insulating filler, an intumescent inorganic heat-insulating filler, reinforced fibers, nano rare earth oxide, a coupling agent, a coalescing agent, a dispersing agent, a thickening agent, a pH regulator, deionized water and the like, wherein the intumescent organic flame retardant is an intumescent flame retardant containing N-P cage type macromolecules. The coating is excellent in fireproof performance, high in expansion multiple and fireproof performance, long in fire-resistant time and excellent in waterproof performance. The invention further discloses a preparation method of the environment-friendly fireproof coating.

Description

technical field [0001] The invention relates to an environment-friendly fireproof paint and a preparation method thereof, and specifically discloses an intumescent fireproof paint which uses an N-P cage macromolecule intumescent flame retardant as a fireproof functional group auxiliary. Background technique [0002] Fire retardant coating is a kind of functional coating, which is widely used in fire protection of steel structures, cables, ceilings, walls, tunnels and aircrafts, etc. It can protect flammable substrates and retard the rapid spread of fire. [0003] According to different base materials, fire retardant coatings can be divided into inorganic fire retardant coatings and organic fire retardant coatings. Inorganic fire-resistant coatings mainly rely on the flame retardancy of the material itself for fire protection, and will not expand and foam. Due to its light density, low thermal conductivity, and good fire resistance, it can meet the fire resistance of 1-2 hour...
