According to the processing technology of the sandstone texture painting board, the antifouling agent and the anti-coking agent are uniformly coated on the seam of the wood of the sandstone texture painting board for three times in total, wherein the interval between every two times is 10-12min, and the antifouling agent is a succinic anhydride derivative, so that the high-temperature oxidation resistance is realized, the polymerization reaction can be effectively inhibited, and the coking is effectively reduced; the method has the advantages that metal deactivation is realized, carbonization reaction of metal ions caused by overhigh temperature in the polishing treatment in the later period is avoided, and the metal ions are combined with an anti-coking agent, so that the metal activity is reduced, the dehydrogenation carbonization reaction can be effectively inhibited, and the quality of sandstone texture painting plate treatment is ensured. This sandstone texture picture panel processing technology, during seamless processing, choose for use liquid to repair to glue and mend the seam and glue the processing, guarantee to fill plump to use the bulging as the standard, can shrink after avoiding the colloid solidification, can present the problem of half seam after polishing, the solidification of stewing, wherein repair glue is two ingredient liquid silica gel, and A component is liquid silica gel, and B component is the silica gel curing agent, wherein A component: the component B = 1: 1, the problem that the colloid is not dried after being placed for a long time or is burnt when being polished at high temperature is avoided. The sandstone texture painting board treatment process comprises the following steps of primary grinding treatment: the 12-head special wood leveling machine is used for polishing and leveling the cut, the height and the scratch caused by the deformation, the pavement and the processing factors of the wood and the construction, and cleaning the pollution of the holes through primary grinding to create conditions for the subsequent hole repairing, fine grinding and other processes. According to the processing technology of the sandstone texture painting board, the sandstone texture painting board is polished by performing primary grinding treatment, middle grinding treatment and fine grinding treatment in a grading manner, so that the polishing quality is improved, and the quality of the sandstone texture painting board is ensured. The sandstone texture painting board treatment process comprises the following steps of: after the steps are completed, the wood is thoroughly dried, the solvent with the alkali-inhibiting factors and the oily protective agent are brushed by a brush to uniformly brush the surface of the wood, and the wood is kept standing for 22 to 26 hours to perform disease-resistant treatment on the sandstone texture painting board so as to ensure the quality of the sandstone texture painting board.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
