Problems solved by technology

A major factor that limits the practical application of transparent decorative fire retardant coatings is the poor flexibility, weather resistance and antibacterial properties of the coating film. After the coating is applied to the substrate and cured, it is prone to cracking of the coating film. If in order to improve the flame retardant The effect of adding inorganic fire retardants will further aggravate the cracking of the coating film

Abstract

The invention discloses a transparent fire retardant coating for building timber. The transparent fire retardant coating is prepared from A, B and C, wherein the A is prepared from the following components: sodium silicate, deionized water, modified calcium carbonate, polyoxyethylene polyoxypropylene ether and sulfonated polyether amine-polybenzimidazole-overbranched polypyrrize terpolymer; the B is prepared from the following components: tetraethyl orthosilicate, 2,2',2'',2'' '-[1,2-ethanetetrayl tetra(4,1-phenylene oxymethylene)] tetraethylene oxide, 6-bromo-1,2-ethylene oxide and ethanol; the C is prepared from the following components: modified nano-silicon dioxide, dimethyl sulfoxide, ethylene glycol, KH-550 and N,N'-carbonyldiiazole.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a transparent fireproof coating for building timber. Background technique [0002] At present, coating fire-resistant coatings is the best means of fire-proofing building wood. When the wood is exposed to fire, it can prolong the fire-resistant time of the wood and slow down the spread of the fire, so that there is enough time for fighting and reducing the losses caused by the fire as much as possible. In the prior art, in order to improve the flame retardant effect, it is generally achieved by adding inorganic fire retardant additives containing P, Si, B, N and other elements. Morphology, and for wood structure fire retardant coatings, its decorativeness is precisely the key factor to be considered: wood is generally used in construction, cultural relic protection, architectural decoration and high-end furniture, and these building materials have ...
