Description
Technical Field
The invention relates to a preparation method of a marble-like coating, in particular to a method for manufacturing a composite marble-like coating based on an elastic multicolor coating.
Background
The stone-like paint is a paint for decorating external wall, and its decorative effect is exactly like marble and granite. The building decorated by the stone paint has natural and real natural color.
The stone-like paint is mainly prepared from high molecular polymer, natural colored stone sand and related auxiliary agents, is hard like stone after being dried and solidified, looks like natural stone, and is widely applied in the building industry at present.
The stone-like paint is divided into sand stone-like paint and rock stone-like paint according to the physical properties of the surface of the object to be constructed.
Although the real stone paint has many advantages, at the same time, it has some defects, which are mainly reflected in:
1. cracks appear in the film forming process: when spraying, the coating is not uniformly covered enough or too thick, cracks can appear after the surface is formed into a film, even peeling can appear after a plurality of weeks, and the situation generally needs to be analyzed specifically, except that the spraying method is noticed during construction, the formula needs to be changed and the coating needs to be prepared again when necessary.
2. Occasionally, cracks appear in the plane: the main reason is that the drying speed of the inner and outer layers is different and the surface is dry and the inner is not dry to form cracks due to the large weather temperature difference and sudden cooling, the field solution is to change a small-nozzle spray gun to spray a plurality of layers thinly, control the drying speed of each layer as much as possible, and better spray distance
3. Sun exposure to yellow:
emulsion (such as styrene-acrylic emulsion and acrylic emulsion) of part of stone-like paint contains a large amount of benzene rings, and a roll color effect is generated after sun irradiation, namely, the benzene rings are decomposed and turn yellow through illumination, so that the decorative effect of stone imitation is influenced again.
4. Cracking:
the stone-like paint is hard and tough, and along with the cracking of the wall base layer, part of the paint film of the stone-like paint is cracked, which is extremely unfavorable for the wall decoration effect.
The water-based multicolor paint is one of the hot spots applied to the field of building interior and exterior wall decorative paints in recent years, has outstanding decorative effect, can be sprayed on the surface of latex colored paint or quartz colored sand paint at one time, can present various colored patterns after being dried, has vivid image effect, has the appearance decorative effect similar to granite, has great price advantage compared with natural granite, and can save the decorative cost.
At present, water-in-water multicolor paint products in the market are different, and in the prior art scheme, the paint is mainly biased towards rigidity, and only the appearance effect (flatness, lightness and thinness and the like) and the engineering cost are emphasized, but the whole weather resistance and the capability of resisting damage of natural factors are neglected, so that the paint products have insufficient flexibility and elasticity. In addition, the selected putty for the exterior of the building is uneven, the paint film performance of the outer facade coating layer is too poor, and even the phenomenon of wall surface efflorescence occurs soon after some coatings are coated, and as the service life of the wall surface paint film is prolonged, the wall surface paint film is easy to crack and fade, the stability of the building structure is finally influenced, the water seepage and the humidity of the building are caused, and the potential safety hazard is increased.
