Description
Technical Field
The invention belongs to the technical field of coatings. More particularly, relates to a water-based flame-retardant coating and a preparation method thereof.
Background
Flame retardant coatings, also known as fire-retardant coatings, are materials that are applied to the surface of flammable substrates to reduce the flammability of the surface of the material being coated to prevent rapid spread of fire, or to the surface of a structure to increase the fire endurance of the structure.
Flame retardant coatings can be classified into intumescent flame retardant coatings and non-intumescent flame retardant coatings according to their combustion characteristics. The non-expansion type flame-retardant coating, also called fire-proof heat-insulating coating, is mostly an inorganic system such as vermiculite cement system, mineral fiber cement system, magnesium hydroxide cement system, etc., the thickness of the coating is generally 8-50mm, and the fire resistance limit can reach 30-180 min. The coating is non-combustible or non-combustible, releases non-combustible gas at high temperature to dilute oxygen or combustible gas, forms a compact glaze film layer at high temperature, can effectively isolate oxygen, and has a certain heat insulation effect within a certain time.
The intumescent flame-retardant coating generally comprises a base material (film-forming substance), a foaming agent, a char-forming agent, a dehydrating agent and an auxiliary agent. The intumescent flame retardant coating has the advantages of less smoke generation during combustion, no toxicity, good flame retardant effect and the like, and has thin coating and excellent decorative performance, thus having higher research value and application value. After the coating is heated to a certain temperature, the film on the surface of the coating is melted and the bubbles rise to form a spongy heat-insulating layer, so that the heat conduction and the heat radiation of flame to the base material can be effectively blocked. The coating is released while the bubbles swell and the gaps of the spongy foaming body are filled with inert or flame-retardant gas, so that flame combustion can be effectively inhibited.
However, most of the non-intumescent flame-retardant coatings are inorganic systems, and the coatings are not good in compatibility with other organic systems, so that the coatings are easy to separate from matrix resin in the storage and use processes of products, and the actual flame-retardant effect of the products is influenced; therefore, how to improve the compatibility between the inorganic flame retardant system and the organic coating resin system and improve the flame retardant stability of the product is one of the technical problems to be solved by the technical personnel in the field.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects and shortcomings that the existing flame-retardant coating is poor in compatibility between an organic resin system and an inorganic flame-retardant system, and is easy to be separated from matrix resin in the storage and use processes of a product, so that the actual flame-retardant effect of the product is influenced, and provides a water-based flame-retardant coating and a preparation method thereof.
The invention aims to provide a water-based flame-retardant coating.
The invention also aims to provide a preparation method of the water-based flame retardant coating.
The above purpose of the invention is realized by the following technical scheme:
an aqueous flame retardant coating comprises an aqueous acrylate emulsion and magnesium hydroxide;
the water-based acrylate emulsion is nano emulsion; the diameter distribution range of the emulsion particles is 1-100 nm;
the surface of the magnesium hydroxide is coated with nano aluminum oxide;
an interlayer exists between the magnesium hydroxide and the nano aluminum oxide;
the interlayer is calcium alginate.
According to the technical scheme, the nano-level water-based acrylate emulsion is used as an organic resin system, and the nano-alumina is coated on the surface of the inorganic flame-retardant material magnesium hydroxide, so that the nano-emulsion can be adsorbed and fixed on the surface of the flame-retardant system due to the high surface energy of the nano-particles, and the nano-emulsion can be better dispersed in a product due to the adsorption and fixation of the nano-emulsion on the surface, so that the inorganic flame-retardant system and the organic resin system are prevented from being separated in the storage process of the product; in the actual use process, when the magnesium hydroxide is abnormally heated, the magnesium hydroxide can be decomposed to generate moisture, and because the surface of the magnesium hydroxide is provided with the coating layer, water vapor can carry the flame retardant to diffuse and permeate to the surface of the product, so that an inorganic flame-retardant layer is formed on the surface of the product; moreover, due to the existence of calcium alginate, calcium ions can catalyze the rapid pyrolysis of the calcium alginate under the heating condition, reduce the surface temperature, dilute the oxygen content and play a good flame-retardant role; and a magnesium oxide-calcium oxide-aluminum oxide composite heat insulation protective layer can be formed on the surface of the product.
Preferably, graphene oxide is also included.
Preferably, polystyrene sodium sulfonate is adsorbed between the graphene oxide layers.
According to the technical scheme, graphene oxide is further introduced, and sodium polystyrene sulfonate is adsorbed between graphene oxide layers, firstly, the interface compatibility between the graphene oxide and a water-based emulsion system can be improved by introducing the sodium polystyrene sulfonate; in addition, when the product is heated, volume expansion or pyrolysis can be preferentially carried out, so that the graphene oxide can rapidly penetrate to the surface to form a protective layer.
Preferably, sepiolite is also included.
Preferably, the metal ions in the sepiolite framework are at least partially substituted by hydrogen ions.
The technical scheme further introduces the sepiolite, and replaces partial metal ions in the sepiolite framework with hydrogen ions to form silicon hydroxyl groups, and when the product is heated, the silicon hydroxyl groups are mutually dehydrated preferentially, so that the effects of cooling and diluting oxygen are achieved; in addition, the existence of silicon hydroxyl can play a role in 'pseudo-sticking' in the product storage process, so that the product forms a stable gelling system, and before the product is used, the product only needs to be simply sheared and dispersed, the fluidity of the product can be quickly recovered, and the product cannot be interfered in use.
