s5, fixing ash: firstly, performing bottom coating, mixing bottom raw lacquer and a diluent in a ratio of 1:1, brushing the mixed liquid on a box body, placing the box body in a shade room for drying, and performing water grinding after drying to smooth the surface of the box body; coating a middle layer of raw lacquer with lacquer and placing the box body in a shade room for drying, and after drying, performing water grinding to grind away convex lacquer particles, wherein the middle layer of raw lacquer has good leveling property and is not easy to leave brush marks, and the scratch generated by abrasive paper can increase the adhesion between the lacquer layer and the lacquer layer after the lacquer is coated; after polishing, performing intermediate coating, wherein the intermediate coating uses black push-coat paint, and a paint film obtained after the black push-coat paint is dried has larger thickness and darker color than a raw paint film; after painting, placing the tire in a shady room with the temperature of about 25 ℃ and the humidity of 70-85% for seven days to finish the spare tire; the purpose of fixing the ash is to allow the gap in the freshly ground paint ash layer to be filled with raw paint to further reinforce the paint ash layer; then, various decorative techniques can be selected on the surface of the box body according to the individual;
s6, coating black push-paint: filtering the black push-polishing paint by using a filter towel, uniformly coating the filtered black push-polishing paint on a box body, after the black push-polishing paint is coated, placing a shady room with the temperature of about 25 ℃ and the humidity of 70-85% for drying, and after drying, polishing by using 600-mesh abrasive paper; it should be noted that the degree of polishing is smooth to the touch and as much as possible to polish off the bright sheets, taking care not to polish through the layer of lacquer coated with lacquer;
s7, texturing: uniformly mixing raw lacquer and egg white according to the ratio of 5: 1 (the egg white can increase the viscosity of the lacquer, but can reduce the purity of the lacquer so that the less the using amount is better, and the filtration is needed after the mixing), spreading the mixed lacquer for 30 minutes, collecting the mixed lacquer for checking the viscosity, spreading the mixed lacquer for 30 minutes again if the ideal state is not reached, and repeatedly spreading the mixed lacquer until the lacquer is in a toothpaste shape to twist the mixed lacquer; uniformly twisting the yarns on the surface of the box body of the sound box, and then placing the yarns in a shady room to be dried thoroughly; three points are needed to be paid attention when twisting; firstly, the twisting height is consistent as much as possible; secondly, the shape, size and style of the twisting are unified as much as possible; thirdly, the density degree between the twists is consistent, the integral distribution is balanced, after the twisting is finished, the twisting is integrally adjusted according to the three requirements, the higher the twisting is, the lower the drying speed is, the easier the twisting is, the better the twisting height is, the humidity in a room does not exceed 70%, the high humidity is easy to wrinkle, the color of the colored paint is darkened, and the colored paint is only required to be placed in a dark and dry environment to wait for complete drying; checking the drying condition, firstly ensuring that the paint surface is formed into a paint film, touching the paint film by hands, slightly pinching the highest twist part by a fingernail, and if the interior of the paint film is soft, indicating that the paint is not completely dried and is still to be dried;
s8, and painting a lacquer with lacquer: mixing gold powder and transparent paint in a ratio of 1:1 to prepare gold paint, firstly dipping a spectacle cloth in alcohol to clean a box body, then sweeping the box body by a brush, uniformly coating the prepared gold paint on the box body, and placing the box body into a shady room to wait for drying after the coat of the lacquer is finished; drying the gold lacquer, and then coating the red lacquer with the coat by using the same method; repeatedly coating lacquer and lacquer with gold lacquer and red lacquer until the height of the lacquer layer and the height of the twist are consistent, and then entering the next working procedure after completely drying; the low concave part of the twist cannot be left with too much lacquer during the coat of the lacquer, so as to avoid the phenomenon of crinkling, which is short for one step, and the whole warp and weft are arranged for several times, so that the thickness of the whole lacquer can be ensured to be consistent, the small pit of the low concave part of the twist is not easy to brush the lacquer, the direction can be changed from up to down and from left to right, and the problem can be solved by using a vertical angle to poke, and the lacquer needs to be carefully observed to check whether the omission and the too thick place exists or not and processed in time in the process of sequentially carrying out the steps; it is to be noted that the coat of lacquer red and the coat of lacquer gold need to be applied separately with two brushes, which may cause color mixing with the same brush;
s9, grinding and displaying: the first grinding is carried out by using 240-mesh abrasive paper for water grinding, the higher-raised twists on the surface of a grinding box body are ground, all the raised twists are ground to the same height, the grinding positions are regularly and continuously changed, the twists can not be tightly seen and ground, the whole body of hands and eyes needs to be carefully touched and observed in the grinding process, all the raised twists are ground to the same height, patterns do not need to be completely ground in the first grinding, a room is reserved for next grinding by using finer abrasive paper, and therefore the grinding is not carried out to a polishing degree once, and the ground paint layer is further dried and hardened after being contacted with air for a period of several days; grinding with 800-mesh abrasive paper to two thirds of the twist height for the second grinding, and reserving a certain space for the next finer grinding;
after the second grinding, dipping the raw lacquer with a cotton ball, uniformly wiping a layer of thin lacquer on the box body, and placing the box body in a shade room for drying after the lacquer is wiped; after drying, the film of the layer is polished by 2000-mesh abrasive paper, and after polishing, the layer is placed for drying in shade for five days; if no reference object exists, the scratches of all 800-mesh abrasive paper are difficult to polish to 2000 meshes only by naked eyes, so that the raw lacquer is thinly wiped on the box body in a wiping mode, but the raw lacquer is not wiped off by using a paper towel, a layer of paint film with a darker color is arranged on the box body after drying and serves as a reference object during polishing, the whole box body can be unified to 2000 meshes by polishing the layer of film by using 2000-mesh abrasive paper, and after the paint film formed by wiping the paint is dried, the layer of paint film serves as a polishing reference object which is finally polished and has unified scratches, and the layer of paint film is polished by using 2000-mesh abrasive paper, so that the scratches are unified to 2000 meshes;
s10, polishing: uniformly coating vegetable oil on a box body position to be polished, coating polishing powder on the box body position, uniformly coating the polishing powder with hand powder and oil, polishing, performing polishing again by using clean pure cotton cloth until the surface of the box body is bright, dipping the oil and the powder on a detergent cleaning box body by using sponge or pure cotton cloth after polishing is finished, and cleaning by using alcohol after cleaning is finished;
