Abstract
The invention discloses a kind of water burnt-in sand environmental protection coating material with the wet on wet construction of high build paint and preparation method thereof, the coating is made up of following raw material by weight：Deionized water, coalescents, preservative, organic-silicon-modified emulsion, defoamer, thickening agent and color tablets containing sand；The color tablets containing sand press 75～80 by the base paint gross weight of each color with Protection glue：60 weight are than composition.Not only texture is more strong but also will not be deposited to bottom because of containing natural colour sand to prepare color tablets containing sand in the coating, affect outward appearance and construction, in terms of construction, high build paint has been constructed under rear hygrometric state, direct spraying water burnt-in sand environmental protection coating material can obtain the imitative bush-hammered face effect for burning stone material, one-shot forming, greatlys save engineering time and material cost.And organic-silicon-modified emulsion used in the coating, film is existing good for machine ground sealing, and with excellent weatherability and stability, simultaneously because emulsion also meets the environment protection requirement of low emission without APEO.
Description
Technical Field
The invention relates to the field of preparation of building coatings, in particular to a sand-in-water environment-friendly coating for wet-on-wet construction with a thick paste coating and a preparation method thereof.
Background
The development and progress of the society enable modern people to continuously improve the understanding of the surrounding environment, protect the earth, protect the health of people and return to the nature, which is a concept that modern people are more and more advocated and pursued. Granite and marble are popular among owners with their solemn texture, durable quality, and various colors. But the disadvantages of granite and marble are also obvious, firstly, the granite and the marble are expensive, secondly, the construction is complex, thirdly, the combination of high self weight and heat preservation is difficult, and a plurality of users are forbidden.
The sand-in-water environment-friendly paint adopts a sand-containing colored particle coating granulation technology, and simultaneously, immiscible colorful sand-containing high-molecular colloid copolymer particles are blended into the paint, so that the paint can create a texture effect almost the same as that of the original stone through one-time spraying, the stone imitation degree is very high, the texture and the stereoscopic impression of the material cannot be achieved by the common paint, and the paint can be comparable to the real stone. In the composition of the sand-in-water environment-friendly coating, the dispersion phase and the dispersion medium are both aqueous systems, so that the sand-in-water environment-friendly coating has small influence on the environment and is more environment-friendly.
The sand-in-water environment-friendly coating has the fundamental condition for replacing stone materials such as natural granite and the like to decorate the exterior wall of the building. The water-coated sand environment-friendly coating has stronger adaptability, can combine professional color matching according to the design requirements of customers on buildings so as to embody infinite creative combinations of the buildings and furthest exert the creative inspiration of architects. The sand-in-water environment-friendly coating is more energy-saving and environment-friendly, and a large amount of natural resources and human resources are consumed in the processes of mining, processing, transporting and installing the natural stone, so that the environment is damaged. The sand-in-water environment-friendly paint thoroughly solves the problem of the oil-in-water method of the traditional colorful paint, has extremely low VOC content, meets the environment-friendly requirement, and is pollution-free during construction. The comprehensive cost is 1/3 which is lower than the comprehensive cost of natural granite, and the popularization and the use are more facilitated.
In recent years, through a large number of demonstration engineering applications, the sand-in-water environment-friendly coating has gradually gained wide acceptance of designers and construction units, the market share has gradually increased, and particularly along with the popularization and application of the external thermal insulation system of the external wall of the building in China, the sand-in-water environment-friendly coating has become one of the preferred finishing materials of the external thermal insulation system of the external wall due to the characteristics of multifunction, high decoration, light weight, safety and the like. With the improvement of appreciation level of people, a colorful coating with an imitation marble flat coating effect can not meet the needs of people, and due to the fact that the fire-burnt stone is in the mainstream of the market gradually due to the effects of bulkiness, atmosphere and texture, the imitation fire-burnt stone effect becomes a trend for the development of the sand-in-water environment-friendly coating. In order to achieve the effect of burning the stone, some domestic companies generally achieve the purpose by using the following two modes: firstly, using texture or real stone paint thick paste type paint as a substrate, brushing same-color intermediate paint for 1-2 times after drying, and then spraying water-based multicolor paint on the surface. When the construction is carried out in winter and rainy season at lower temperature, the thick paste type coating must be completely dried, and then the multicolor coating is carried out, so that the construction time is longer, and the final color point floats on the surface of the substrate because the color point of the water-based multicolor coating is not well fused with the substrate, so that the effect of imitating the burnt stone is poor. And secondly, the sand-in-water coating is used traditionally. Compared with the first method, the method has certain improvement on the construction times, but has a bottleneck on the mass production technology, the color grains are easy to break and bleed, and the phenomena of easy layering and caking exist on storage.
The raw materials of various colors of the sand-in-water environment-friendly coating can be realized by industrial production, the sand-in-water environment-friendly coating is a new generation product, and after the thick paste type coating is constructed in the construction aspect, the sand-in-water environment-friendly coating can be directly sprayed in a wet state. In the process, the same-color intermediate paint can be saved for 2 times, so that the construction process, the construction time and the material cost are saved. Meanwhile, as the color particles in the water-coated sand environment-friendly coating contain natural color sand, the effect of burning stone materials which is almost the same as that of the original stone can be created, so that the final spraying effect is more vivid, and the simulation degree can reach 100%. The production process of the sand-in-water environment-friendly coating in the production aspect is simple, has little difference with normal water-in-water multicolor production, has stable color particles, has no obvious phenomena of color bleeding and breakage, has good production batch and reproducibility, and has operability of mass production.
The prior sand-in-water coating has the problems of high sand content, complex production process, bottleneck point in the production technology, high construction material consumption, poor product stability, easy breakage of color points, low production efficiency, large difference between product batches and the like.
