A method for surface preparation of solid substances by which the solid substances can be improved in the tight adhesion to coating films made from ultraviolet-curing resins or the like; and surface-prepared solid substances. The method comprises treating the whole or part of a solid substance with a flame of a fuel gas containing a specific silicon compound having a flash point ranging from 0 to 100~C and a boiling point ranging from 105 to 250~C, e.g., hexamethyldisilazane, vinyltri- methoxysilane, trifluoropropyltrimethoxysilane, or 3-chloro- propyltrimethoxysilane to conduct flame silicification.
L'invention concerne un procédé de préparation de surface de substances solides permettant d'améliorer l'adhérence desdites substances solides à des pellicules de revêtement composées de résines durcissables aux ultraviolets ou similaires, ainsi que les substances solides préparées en surface. Le procédé selon l'invention consiste à traiter l'ensemble ou une partie d'une substance solide au moyen d'une flamme d'un gaz combustible contenant un composé de silicone spécifique, présentant un point d'éclair compris entre 0 et 100 ·C, et un point d'ébullition compris entre 105 et 250 ·C, par ex. hexaméthyldisilazane, vinyltriméthoxysilane, trifluoropropyltriméthoxysilane ou 3-chloropropyltriméthoxysilane, afin de réaliser une silicification à la flamme.
