Description

Inorganic interior wall heat-insulating flame-retardant coating and preparation method thereof
Technical Field
The invention relates to the field of building coatings, in particular to an inorganic interior wall heat-insulating flame-retardant coating and a preparation method thereof.
Background
In recent years, due to the development of the heat insulation technology of the external wall, the heat insulation paint of the building wall is gradually changed from the internal wall to the external wall. The reflective heat-insulating coating achieves the purposes of increasing the surface heat reflectivity and reducing the heat accumulation of the coating by selecting proper base materials, functional pigments and fillers and a production process, so that the heat-insulating and temperature-reducing effects are achieved. Under the same conditions of base materials, the pigment and filler which are important components of the coating play a leading role in the reflective insulation effect.
The hollow glass bead or hollow ceramic bead is a closed-pore thin-wall spherical particle made of oxides containing elements such as silicon, aluminum and the like through a special process, the sphere is usually in a micron-sized size, and air or inert gas with low heat conductivity coefficient is filled in the sphere, so that the hollow glass bead or hollow ceramic bead is low in density and small in heat conductivity coefficient, and can well retard heat energy to be transferred to the interior of an object. In addition, the specific surface area of the glass beads and the ceramic beads is large, the reflectivity of the surface layer material to infrared electromagnetic waves in all directions is extremely high, the reflective and heat-insulating properties of the coating can be greatly improved, and the advantages make the surface layer material become the preferred filler of the reflective and heat-insulating coating.
CN201610294758.X A wear-resistant fireproof modified coating for building interior wall comprises organosilicon modified epoxy acrylate, vinyl acetate homopolymer emulsion, acrylic emulsion, styrene-acrylate copolymer emulsion, silica sol, hollow glass microsphere, etc., wherein organosilicon modified epoxy acrylate is cooperated with film-forming reinforcing substances such as vinyl acetate homopolymer emulsion, acrylic emulsion, styrene-acrylate copolymer emulsion and silica sol, so as to effectively improve wear resistance and fireproof performance of organosilicon modified epoxy acrylate; the added filler is effectively combined with the film forming substance under the action of the auxiliary agent titanate coupling agent NDZ-201, so that the wear resistance and the fire resistance of the film forming substance of the main material are improved; the added auxiliary agent and reinforcing agent can effectively improve the comprehensive performance of the coating.
CN201810699744.5 an environmental protection reflective building insulation heat insulation coating and a preparation method thereof, the raw materials also comprise polyacrylate emulsion, modified ceramic microspheres, silica sol and the like, polylactic acid resin, dispersible rubber powder and titanium dioxide are adopted to be sprayed on the surfaces of the ceramic microspheres after being melted, materials beneficial to light reflection are added, the ceramic microspheres are not easy to damage after the surfaces of the ceramic microspheres are modified, the volume weight stability of an inorganic insulation mortar body is ensured, and the stability of a heat conductivity coefficient is ensured; in addition, the light reflection performance is effectively improved, and the heat preservation performance is effectively improved. The modified ceramic microspheres, the far infrared ceramic powder and the rutile type titanium dioxide are used as main materials for light reflection, so that the coating has a good effect of reflecting light and heat. The inventive concept in this patent document is somewhat similar to the present invention, but the microsphere type is different.
At present, ceramic microspheres are used in the traditional reflective heat-insulation coating, but the ceramic microspheres are fragile in the stirring process, so that part of the ceramic microsphere heat-insulation coating is high in water absorption rate, poor in compatibility of the ceramic microspheres and an adhesive and the like, and further the defects that the overall reflective heat-insulation effect is poor, the performance is unstable, the production process is not easy to control and the like are influenced.
In summary, the water-based inorganic interior wall coating on the market at present has a single function, or only has flame retardance and fire resistance, or only has a heat preservation and heat insulation function, or only can avoid thick coating cracking, and the interior wall coating with the comprehensive effect is lacked.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides an inorganic interior wall heat-insulating flame-retardant coating and a preparation method thereof. The coating takes silica sol and hydrophobic acrylic emulsion as main film forming substances, and pigments and fillers such as anatase titanium dioxide and reflective heat insulation microspheres are added, so that the purposes of attractive decoration, flame retardance, heat preservation and heat insulation and no cracking of thick coating are achieved, and the pursuit of the market on health and environmental protection is met.
The invention adopts the following technical scheme:
firstly, the inorganic heat-insulating flame-retardant coating for the inner wall comprises the following components in percentage by mass: silica sol: 20-30%, hydrophobic acrylic emulsion: 5-10%, anatase titanium dioxide: 2-4%, reflective insulation microsphere: 10-20%, film-forming aid: 0.5-1.0 percent of rheological additive, 0.3-1 percent of other additive, and the balance of water.
Preferably, the silica sol is SiO 2 The contents are as follows: 24-28%, pH:9-9.5 of SiO 2 Particle size: 7-15nm.
The silica sol used in the invention has a structure of silicic acid colloid sphere, and has the characteristics of good bonding force, nonflammability and the like.
The hydrophobic acrylic emulsion used in the invention has excellent compatibility and bonding force with the low-thermal-conductivity heat-insulating filler, so that the paint film can provide excellent heat-insulating performance and excellent heat-preserving performanceAdhesion, water resistance, flexibility, no cracking of thick coating, extremely low VOC release and the like. For example: maincote of the Dow chemical TM IC-1002 emulsions.
The reflective heat-insulating microspheres used in the invention are composed of thermoplastic expandable microspheres and silicate layers coated on the surfaces of the expandable microspheres, wherein the silicate layers do not contain boron and sulfur (such as the composite microspheres described in patent application CN 114602396A). The fluidity is good, and the dispersion is easy and uniform; the dyeing property is good, and various application scenes are met; the cutting-resistant and non-brittle glass is suitable for various base materials, and is stable and efficient; low heat conductivity coefficient, moisture and leakage prevention, high temperature and corrosion resistance, high strength, low density, no environmental pollution and the like. Compared with ceramic microspheres and hollow glass microspheres, the shell is made of thermoplastic polymer, so that the shell has resilience, is not easy to break and is easier to mix and grind.
The film forming aid used in the invention is a non-VOC film forming aid. For example: isyman OE-300.
The thickener for the interior wall coating mainly comprises hydroxyethyl cellulose.
The other auxiliary agents used in the invention are selected from one or more of dispersing agents, defoaming agents, antifreezing agents and other common coating auxiliary agents.
The process comprises the following steps: sequentially adding other auxiliary agents and anatase titanium dioxide under stirring of part of water, uniformly dispersing (1200 r/min, dispersing for 10-15 min) to a specified fineness (preferably below 30 microns), adding rheological auxiliary agents (diluted by part of water in advance), and uniformly dispersing at a high speed; then adding the hydrophobic acrylic emulsion, the film-forming assistant and the silica sol under stirring, adding the reflective heat-insulating microspheres after uniformly mixing, and uniformly dispersing (1000 r/min, dispersion for 10-15 minutes).
The invention has the following beneficial effects:
the hydrophobic acrylic emulsion in the coating component has the characteristics of excellent pigment compatibility, high pigment bearing capacity, excellent high film thickness without cracking, excellent flexibility and the like, in particular the Dow chemical MAINCOTE TM The effect of the IC-1002 emulsion is better. Has excellent compatibility with other components such as reflective heat-insulating microspheres, anatase titanium dioxide and the like, so that a paint film has excellent heat insulationThe heat preservation performance, the characteristics of excellent adhesive force, water resistance, flexibility and the like are provided, and VOC and paint film odor are greatly reduced. The reflective heat-insulating microspheres in the coating have the characteristics of light weight and very low heat conductivity coefficient (the heat conductivity coefficient is much lower than that of the hollow microspheres and the ceramic microspheres). Can greatly reduce heat conduction, thereby playing the role of heat insulation and preservation and simultaneously solving the problem that the glass beads and the ceramic beads are easy to break in the production process. The silica sol has stronger penetrability to the base layer and can permeate into the base layer through the capillary, so that the binding power among the components of the coating is further enhanced; and silicon-oxygen bonds are formed among the silica sol particles, the melting point is as high as 1600 ℃, and the purposes of fire prevention and flame retardance can be achieved. In conclusion, the components in the inorganic interior wall heat-insulating flame-retardant coating formula system, especially the hydrophobic acrylic emulsion, the reflective heat-insulating microspheres and the silica sol play an especially important role in the formula, respectively play excellent characteristics, and simultaneously can be cooperated with other components to maximally enhance the functions of the components, so that the coating forms a uniform and compatible whole, and excellent performances such as water resistance, flexibility, heat insulation, fire prevention, flame retardance, thick coating no cracking and the like are realized. The coating is very simple in production process, low in cost, convenient and fast to construct, and construction procedures are reduced. The coating is mainly aimed at the surface coating of indoor wall surfaces, and can be directly coated on indoor base layers without using putty and alkali-resistant primer, so that one construction procedure is saved, and the construction cost is further reduced. Has certain functions of decoration, flame retardation, heat preservation and moisture prevention.
