The present invention provides:
a method of forming a simulated wood grain wall surface, the method being performed using a spray apparatus, the method comprising the steps of:
s1, covering a wall surface with a reinforcing treatment agent to form a reinforcing layer 1a; before construction, the wall surface should be noted to have no clear water, no floating dust, no greasy dirt and the like, the wall surface is uniformly brushed for 1-2 times by using a rolling brush or a hairbrush, the wall surface cannot be neglected to be coated, and the next construction link can be carried out when the coating is dry.
S2, after the reinforcing layer 1a is dried, covering the wall surface with gypsum and leveling to form a gypsum layer 1b; according to the flatness of the base material, when the leveling gypsum is moderately modulated, a 2M guiding rule is used for leveling the wall surface, and the whole leveling is always observed by side light or the phenomenon of no obvious bright seam is detected by using the guiding rule.
S3, after the gypsum layer 1b is dried, covering the wall surface with water-resistant putty to form a water-resistant putty layer 1c; filling and trimming larger pores and cracks on the base material with caulking cement mortar, and filling the water-proof putty for the first time. After the putty film is dried (generally not less than 8 hours in late autumn), the severely uneven part is slightly polished, floating ash is removed, the inner wall waterproof putty is scraped for the second time, the scraping is as smooth as possible, and the polishing area for the second time is reduced. The thickness of each scraping can not be too thick, and is generally about 0.5-1 mm in each pass. After the putty knife coating process is finished, the putty film needs to be thoroughly dried and cured, and the curing time is generally 3-5 days. When the PH of the putty film is less than or equal to 10, the water content is less than or equal to 10 percent.
S4, polishing the wall surface to be flat after the waterproof putty layer 1c is dried; the dustproof mask, the putty knife, the sand paper, the sand rack, the footstool and the hand-held incandescent safety lamp are prepared, the 360-mesh sand paper is used for integrally polishing, the safety lamp is used for observing whether the polished part has unevenness and pits or small spots at any time, and if the polished part is even, the polishing treatment is continued.
S5, covering the water-resistant putty layer 1c with a primer to form a primer layer 1d. After the wall surface is polished, dust is cleaned and whether defects exist or not is observed, if the defects exist, the wall surface is repaired, then the wall surface is uniformly coated (sprayed/rolled) with penetrating primer once (sagging and uneven coating cannot occur), and the wall surface is generally dried for 4-6 hours to carry out subsequent construction.
S6, spraying wood grain primer on the wall surface by using spraying equipment to form a wood grain primer layer 1e; the viscosity of the primer paint is controlled between 80 KU and 90KU (stormer viscometer TM-IVB paint viscosity tester), and the primer paint is uniformly and fully coated on the decorated surface for two times (the first time and the second time are 4-6 hours apart at normal temperature).
S7, after the wood grain primer layer 1e is dried, spraying wood grain finish paint on the wood grain primer layer 1e by using spraying equipment to form a wood grain finish paint layer 1f; the viscosity of the finish paint is controlled between 60 KU and 70KU (stormer viscometer TM-IVB paint viscosity tester), and the finish paint is quickly and evenly coated on the texture required direction of the decorated surface.
S8, before the wood grain finish paint layer 1f is dried, a wood grain machine is used for scraping wood grain texture on the wood grain finish paint layer 1 f. The horizontal (vertical) line corresponding to the width of the wood grain device is quickly found by infrared rays at the position coated with the wood grain finishing paint, the corresponding texture is quickly scraped according to the requirement of imitated texture, the first difference of the second stubble is that stubble pressing treatment is needed, one centimeter (1 cm) stubble pressing is reserved in general to basically meet the requirement of texture engagement, and the like is carried out afterwards.
Based on the above embodiments, the technical problem to be solved by the present invention is how to form a wood-like grain layer on a wall surface. Therefore, the invention forms wood grain texture on the wall surface through the steps S6 to S8, and simultaneously, in order to ensure high efficiency of spraying the wood grain base paint and the wood grain surface paint, the invention also uses spraying equipment to carry out spraying operation.
S9, polishing the surface of the wood grain finish paint layer 1f after the wood grain finish paint layer 1f is dried; the scraped wood grain is lightly polished by using 360-mesh sand paper after 24 hours at normal temperature, the wood grain primer cannot be damaged, the polishing purpose is to smooth the surface of the scraped wood grain, reduce the surface sharpening phenomenon, and lay a foundation for the follow-up scraping of transparent putty.
S10, covering the surface of the wood grain finish paint layer 1f with transparent putty to form a transparent putty layer 1g.
The specific operation of step S10 is as follows:
s10a, after the polished working surface is cleaned, uniformly scraping the finished water-based transparent putty on the surface of the wood grain by using a trowel, wherein the surface is not too thick during scraping, and flattening and light receiving are carried out by taking the protruding part of the wood grain as a reference point.
S10b, after the glass is dried (the glass is usually subjected to 12h at room temperature), 320-mesh sand paper is used for neatly polishing in an arc action, so that the glass is more effectively connected for subsequent operation and the surface unevenness is observed.
S10c, scraping the second-pass water-based transparent putty, uniformly and fully covering the construction surface according to the grain direction, and airing and drying after flattening and light receiving.
S11, polishing the surface of the transparent putty layer 1g after the transparent putty layer 1g is dried; and (3) after the transparent putty after the scraping construction is completely dried, uniformly grinding and flattening the transparent putty by using 360-mesh sand paper, and cleaning dust on the surface of the transparent putty to be painted (roller painting/spraying) with the self-cleaning finish paint.
S12, covering the surface of the transparent putty layer 1g with self-cleaning finish paint to form a self-cleaning layer 1h.
The self-cleaning finishing varnish has no requirement on viscosity in the general case, only a small amount of clear water can be properly added to dilute the self-cleaning finishing varnish according to the change of the construction environment temperature in the application process, so that the self-cleaning finishing varnish can meet the application requirement, construction under the environment conditions that the air temperature is lower than 5 ℃, higher than 30 ℃ and the relative humidity is higher than 85% is avoided, and the construction should be stopped when the wind force is more than or equal to 4 levels. If it is self-cleaning
If the thickness or the surface hand feeling of the finish paint has certain requirements, the finish paint can be lightly and uniformly ground by 600-mesh sand paper after the first construction is completely dried, the ground surface is cleaned and cleaned, and then the self-cleaning finish paint is coated (roller coating/brush coating/spray coating) once, and the sagging phenomenon cannot occur.

Based on the above embodiment, the technical problem to be solved by the invention is that the existing spraying equipment cannot pitch the shooting hopper and cannot spray the shooting hopper on the top and the bottom of the wall.
Therefore, the invention modifies the injection hopper 3 to be rotatable on the self-propelled device 2 so that the first discharge port 3b of the self-propelled device has a pitching function, thus the paint entering the injection hopper 3 through the first feed port 3a flows onto the throwing roller 5, and the first driver 4 drives the throwing roller 5 to rotate so that the paint is obliquely thrown onto the wall surface through the first discharge port 3b under the action of centrifugal force.
Meanwhile, the storage hopper 7 which is originally integrated with the injection hopper 3 is separated, so that the storage hopper 7 is independently erected above the first feed inlet 3a and is supported by at least two parallel rollers 3c, so that no matter how the injection hopper 3 is pitching, the storage hopper 7 always keeps the original posture under the action of gravity, and the overflow of the paint stored in the storage hopper 7 along with the pitching of the injection hopper 3 is avoided.
Also to be described is: the second driver 6 is a motor.
Further:
the self-propelled device 2 comprises a first travelling device and a second travelling device, the first travelling device is arranged on the ground, the second travelling device is arranged on an executing part of the first travelling device, the first travelling device is used for driving the second travelling device to horizontally move, the injection hopper 3 is rotatably arranged on an executing part of the second travelling device, and the second travelling device is used for driving the injection hopper 3 to vertically move.

In the prior art, the first running gear is usually a cart placed on the ground, the second running gear is usually an elevator mounted on the cart, its power source is a motor, its transmission mechanism is a roller chain, and since it is too common, it is not described here in detail, and the self-propelled device 2 only shows the execution part of its second running gear as a schematic in the figure.
In view of the fact that the second drive 6 prevents the hoppers 3 from spraying the edges of the wall, there is no limit to the number of hoppers 3 mounted on the self-propelled device 2, preferably two hoppers 3, and the second drive 6 mounted on two hoppers 3 is located between two hoppers 3 so that the second drive 6 does not prevent the hoppers 3 from spraying the edges of the wall.
Further: the bottom surface of the injection hopper 3 is obliquely arranged, and the height of the part of the bottom surface of the injection hopper 3 close to the first discharge hole 3b is lower.
Based on the above embodiment, the technical problem to be solved by the present invention is how paint flows from the first feed port 3a to the throwing roller 5 when the first driver 4 drives the shooting hopper 3 to rise.
For this reason, the present invention is configured such that the bottom surface of the hopper 3 is sufficiently inclined so that the paint can still flow from the first inlet 3a to the first outlet 3b when the hopper 3 is tilted up.
Further: the top of self-propelled device 2 is provided with first articulated seat 2a and second articulated seat 2b, the bottom of penetrating hopper 3 is provided with third articulated seat 3d and fourth articulated seat 3e, third articulated seat 3d and fourth articulated seat 3e are close to first feed inlet 3a and first discharge gate 3b respectively, first articulated seat 2a and third articulated seat 3d articulate, the non-execution portion of first driver 4 articulates with second articulated seat 2b, the execution portion of first driver 4 articulates with fourth articulated seat 3e, first driver 4 is used for driving fourth articulated seat 3e to be close to or keep away from second articulated seat 2b.
Based on the above embodiment, the technical problem to be solved by the present invention is how the first driver 4 drives the shooting hopper 3 to make a pitching motion.
Therefore, the invention uses the electric push rod as the first driver 4 to drive the fourth hinging seat 3e and the second hinging seat 2b to be relatively close to or far away from each other, and the injection hopper 3 is hinged with the self-propelled device 2 through the first hinging seat 2a and the third hinging seat 3d, so that when the second hinging seat 2b and the fourth hinging seat 3e are close to or far away from each other, one end of the injection hopper 3 close to the first discharge hole 3b performs pitching action.
Further: a valve 8 is installed at the bottom of the storage hopper 7, and the valve 8 selectively opens and closes the second discharge port 7b.
Based on the above embodiment, the technical problem to be solved by the present invention is how to avoid paint flowing out from the first discharge port 3b when the wall surface is stopped or replaced.
Therefore, the invention can avoid paint flowing out by installing the valve 8 at the bottom of the storage hopper 7 to close the second discharge port 7b, and the valve 8 can open the second discharge port 7b during operation.
