Description
Technical Field
The invention relates to the technical field of coatings for buildings, in particular to an ultrathin composite rock slice stone-like paint and a preparation method and application thereof.
Background
The stone-like paint is used to imitate outer wall stone, and is a single-component paint for building outer wall, which is produced by suspending two or more kinds of water-based color particles in a water-based interlayer and spraying once.
The domestic existing stone-like coating is mainly products such as real stone paint, water-in-water, sand-in-water and the like; when products such as water-in-water products, water-in-sand products and the like are manufactured and produced, simulation is carried out on each color according to the color and pattern effect of the stone, patterns with each size are cut respectively and then mixed, and a large amount of manpower and electric power are consumed; the stone-like paint is prepared from stone powder or sand, sand grains and rock slices with various colors, is applied to the stone imitation of the building wall, has the advantages of strong decoration, wide application range, water-based environmental protection, good pollution resistance, long service life, no potential safety hazard and the like, and is widely applied to the decoration and protection of the building wall.
In the prior art, the stone-like paint mainly comprises colored sand stone-like paint and rock slice stone-like paint; the traditional rock slice real stone paint is prepared by adding hard rock slices into paint vehicle, the toughness of the hard rock slices is good, and the compatibility with the paint vehicle is poor, so that the hard rock slices are different from sand in specific weight during spraying construction, and the rock slices are subjected to large resistance and are easy to generate flying slices; after the construction is finished, the rock slices protrude out of the surface of the coating, the fidelity is low, the adhesive force with the paint film is poor, the firmness is low, the rock slices are easy to fall off from the paint film, the weather resistance and the durability are poor, and the decorative effect is influenced.
Disclosure of Invention
Aiming at the defects in the prior art, the first purpose of the invention is to provide the ultrathin composite rock slice stone-like paint, which improves the compatibility of the ultrathin composite rock slice and the paint, thereby improving the fidelity of the paint film and improving the decorative effect.
The first purpose of the invention is realized by the following technical scheme:
The ultrathin composite rock slice real stone paint is prepared from the following components in parts by weight: 10-20 parts of ultrathin composite rock slices, 20-30 parts of pure acrylic emulsion, 78-25 parts of deionized water A15, 15-22 parts of deionized water B, 15-25 parts of quartz sand, 0.1-0.3 part of preservative, 0.5-2 parts of antifreezing agent, 0.1-0.3 part of defoaming agent, 0.5-2 parts of film-forming additive, 0.08-1.0 part of aluminum magnesium silicate thixotropic lubricant, 0-0.1 part of multifunctional amine and 0.1-0.5 part of thickening agent.
by adopting the technical scheme, the ultrathin composite rock slice is a soft and elastic irregular sheet-shaped assembly with the thickness of 0.07mm and the size of 1-8mm, and the color of the ultrathin composite rock slice is formed by natural inorganic elements and cannot fade; the colorful composite rock slice is formed by compounding inorganic materials and acrylic polymers, and can be tightly combined with various water-based stone paints; the thinner and lighter the single piece of the rock slice is, the better the toughness is, the better the compatibility with the real stone paint is, the better the spraying effect is during construction, and the less the amount is used. The invention adopts the ultrathin composite rock slice, so that the soft and ultralight rock slice has good combination degree with other materials, no flying slice is generated during spraying, the rock slice is integrated with paint after spraying, and the rock slice is firm and has high fidelity; in addition, the thickness of the ultrathin rock slice is 1/4 of that of a common rock slice, and the number of the ultrathin rock slice is 4 times that of the common rock slice with the same weight; thus, the ultra-thin rock slices increase the pattern density imitated by the paint per unit weight; further improving the simulation effect of the stone-like paint. The basic material of the magnesium aluminum silicate thixotropic lubricant is taken from lamellar silicate mineral materials, and in an aqueous system, the lamellar silicate mineral materials can form a 'card palace' type association network structure, and in the formed association network structure system, the system is very stable, can generate stable, effective and homogeneous lifting and suspending on solid particles, emulsion and gas in the system, and can prevent the solid particles, the emulsion and the gas from sinking due to the action of gravity, so that the unique and excellent anti-sinking performance of the magnesium aluminum silicate is realized. In addition, the aluminum magnesium silicate plays a thixotropic role in the coating, if enough shearing force is applied to the structure, the card palace type association network structure is broken, so that the viscosity of the system is greatly reduced, the fluidity is improved, and if the external shearing force is stopped, the system can be reversed and cyclically reciprocated as required.
Preferably, the composition is prepared from the following components in parts by weight: 13-17 parts of ultrathin composite rock slices, 22-25 parts of pure acrylic emulsion, 20-22 parts of deionized water A, 17-20 parts of deionized water B, 18-23 parts of quartz sand, 0.15-0.20 part of preservative, 1.2-1.5 parts of antifreezing agent, 0.1-0.2 part of defoaming agent, 0.7-1.2 parts of film-forming additive, 0.2-0.9 part of aluminum magnesium silicate thixotropic lubricant, 0-0.1 part of multifunctional amine and 0.2-0.4 part of thickening agent.
by adopting the technical scheme, the content of each component is optimized, and the comprehensive performance of the stone-like paint is further improved. The quartz sand and the rock slices are used for replacing the color sand, so that the fidelity is improved, and the color sand ore resource is saved. The quartz sand is easy to obtain relative to the colored sand ore, and the colored sand is less in accordance with the requirement of exploiting a large amount of ore resources. The system uses the ultrathin rock slices to replace color sand, reduces the using amount of the sand, and partially uses quartz sand to ensure that the product has the texture of natural stone.
Preferably, the preservative is a preservative LX150 or K14 preservative.
preferably, the magnesium aluminum silicate thixotropic lubricant is PT-XL19 or TEROGEL KW rheological aid.
Preferably, the antifreeze agent is propylene glycol.
Preferably, the defoamer is a mineral oil defoamer.
Preferably, the coalescing agent is 2,2, 4-trimethyl-1, 3-pentanediol monoisobutyrate.
preferably, the thickener is an associative acrylic thickener.
the second purpose of the invention is to provide a preparation method of the ultrathin composite rock slice real stone paint, which is obtained by the following processing steps:
Mixing the deionized water A and the aluminum magnesium silicate thixotropic lubricant together, stirring at the rotating speed of 1200-1500r/min until the aluminum magnesium silicate thixotropic lubricant is fully dissolved, and standing for 12-20h to obtain a mixture A;
Transferring the mixture A into a paddle type stirrer, adding deionized water B, sequentially adding a preservative, an antifreezing agent, a defoaming agent, a film-forming assistant and multifunctional amine in sequence at a rotating speed of 80-100r/min, and uniformly stirring to obtain a mixture B; adding ultrathin composite rock slices through a screen with 10mm × 10mm meshes at a rotating speed of 30-40r/min to obtain a mixture B;
And adding the pure acrylic emulsion after the rock slices are added and stirred uniformly, stirring uniformly, adding quartz sand at the rotating speed of 25-30r/min, stirring uniformly, and adding the thickening agent to obtain the ultrathin composite rock slice true stone paint.
By adopting the technical scheme, the aluminum magnesium silicate thixotropic agent needs to be dispersed in an aqueous medium at a high speed, the concentration is not low during dispersion, the aluminum magnesium silicate thixotropic agent is dispersed into a slurry state and is placed for more than 12 hours, and the aluminum magnesium silicate fully absorbs water and becomes a metastable state; when in use, the mixture is diluted, so that other materials can be conveniently mixed; adding other additives, wherein the preservative plays a role in preventing putrefaction, the antifreezing agent plays a role in storing at low temperature and adjusting drying time, the defoaming agent prevents the system from foaming in the system and adjusts the product state and the effect in construction, the film-forming additive helps emulsion with high Tg (glass transition temperature) to form a good film at low temperature, and the multifunctional amine is mainly used for adjusting the weak alkaline state of the system in the system, and the coating is easy to putrefaction and deteriorate under the acidic condition;
The paddle type stirring equipment can well and uniformly mix materials under the low-speed condition, and the high-speed dispersing equipment is not suitable for mixing a high-viscosity system; the ultra-thin rock slices can be crushed at an excessively high speed, and the mixing efficiency is low due to an excessively low speed, so that the production efficiency is influenced; adding the rock slices by using a screen with the size of 10mm multiplied by 10mm to ensure that the rock slices are uniformly added into the slurry; the problem that the quality of the product is affected by conglomeration formed by sticking rock slices together when meeting water caused by stirring a large amount of rock slices into the slurry after mixing is avoided;
The emulsion is added before the rock slices and is easy to react with the rock slices and agglomerate, so the emulsion is added after the rock slices are uniformly stirred; the rotating speed is further reduced after the uniform stirring, because the friction force of the system is increased after the sand is added, the rock slices are easily worn by the sand, and the speed is reduced to 25-30 r/min; after sand is added and stirred uniformly, the viscosity is adjusted to 105KU, so that the time of the system at 105KU is shorter, the stirring time at high viscosity is shortened, and the damage of rock slices is avoided; under the anti-settling effect of the magnesium aluminum silicate thixotropic lubricant, the viscosity of the system is adjusted to 105KU, and the sand can be effectively prevented from settling.
The third purpose of the invention is to provide an application of the ultrathin composite rock slice stone-like paint in building surface decoration, which comprises the following construction operations: surface treatment of a building base layer, smearing and plastering fine mortar, roller coating of a transparent primer for an outer wall, roller coating of a special middle layer paint, line drawing, tape pasting, spraying of an ultrathin rock slice stone-like paint and brushing of a finishing varnish.
By adopting the technical scheme, the ultrathin composite rock slice real stone paint product is less prone to flying than rock slice real stone paint, good in fusion degree and high in simulation degree, the consumption is 1.5-2kg/m 2, the consumption is lower than that of real stone paint and rock slice real stone paint, the self weight after drying is lower than 1kg/m 2, the self weight is low, the adhesive force with a base material is good, and the ultrathin composite rock slice real stone paint product is not prone to falling off.
In conclusion, the invention has the following beneficial effects:
(1) The ultrathin composite rock slices in the paint can vividly imitate various patterns on the stone, the vividness is good, the workload during proofing and production is greatly reduced, and the working efficiency is improved;
(2) According to the invention, the ultrathin composite rock slices and the quartz sand are used for replacing the colored sand, so that the exploitation of mineral products is reduced, the usage amount of color matching materials in the same amount of real stone paint is reduced, and resources are saved; wherein, the amount of sand required by the invention in the same amount of the stone-like paint is 15-20%, the amount of the rock slices is 15-20%, and the amount is far lower than 75% of the amount of the color sand in the common stone-like paint and the rock slice stone-like paint;
(3) The ultrathin composite rock slices are matched with the aluminum magnesium silicate thixotropic lubricant, the acrylic emulsion and other additives, so that the ultrathin composite rock slices can be well blended with paint, the weather resistance and the durability of the stone-like paint are improved, and the decorative effect is improved.
