Technical Field

The invention relates to an old wall renovating technology, in particular to a quick and environment-friendly wall surface renovating method.

Background

The wall surface coating is used for decorating and protecting the building wall surface, so that the building wall surface is attractive and tidy, and meanwhile, the wall surface coating can also play a role in protecting the building wall surface and prolonging the service life of the building wall surface. In the specific technical field, the development of various binder film-forming technologies makes great progress on the performance of the coating, and the development of emulsion preparation technology is particularly important. The coating wall surface system is the most widely applied wall surface system at present, and accounts for more than 80 percent of the whole wall surface market. The paint wall surface system consists of a putty leveling layer and paint. Because the putty leveling layer in the system has low strength and poor stability in long-term use performance, the phenomena of cracking, bulging, peeling, falling and the like generally exist on the wall surface of the coating, and the normal use is seriously influenced. Moreover, the decorative paint on the surface has the phenomena of pulverization, color difference, pollution and the like after long-term use, and the attractiveness of the paint wall surface is seriously influenced. Therefore, the wall surface needs to be renovated at regular intervals.

The existing paint wall surface renovating method has two modes, 1) if the using time of the putty layer is short, the putty layer can not be removed, but the original wall surface needs to be polished, then primer is coated, and finally finish paint is coated; in this case, as the interior putty ages, it needs to be quickly refurbished again. 2) In most cases, a damaged old putty layer needs to be removed by shoveling, a new putty layer needs to be scraped again, and in the process of scraping the putty layer, the surfaces of putty and the like have obvious scratches and need to be polished and leveled again, and then a finishing coating is coated; this process flow is used as is currently active in the market, Nippon Refresh.

However, the existing wall surface renovating process has the defects of long construction period, more building wastes, generation of a large amount of dust and noise in the construction process, and particularly, the polishing of a putty layer or the polishing of an original wall surface can generate a large amount of dust, the fine particle dust particles are extremely small, the fine particle dust particles are easily adsorbed on the surfaces of other objects under the action of static electricity, surface tension and the like, but if the polishing and leveling are not performed, the surface decoration of the renovated wall surface can be seriously influenced, and the adhesion between the wall body and a coating at the back can be seriously influenced.

Meanwhile, when the wall surface is renovated, people in a house must be evacuated, and objects are wrapped, so that the experience of customers for renovating the old wall is poor. Because of these problems, many users prefer not to perform the renovation even if the wall coating material cracks, peels, or the like, without seriously affecting the use. In addition, the surface strength of the renovated coated wall surface is low, and the phenomena of scraping, cracking and the like can be generated.

Based on the current situation, the field of renovating old coating wall surfaces lacks a green and environment-friendly renovating method which is convenient, rapid, clean, dustless, less in construction waste generation and noiseless in construction.
