Wherein in an embodiment, step (3) is sprayed after described toner compound is first crossed 30-50 mesh sieve again.
Principle of the present invention and advantage as follows:
Quartzite slate of the present invention adjusts the weight part consumption of each raw material by great many of experiments, each component compatibility is reasonable, stable processing technique can be made, the good article rate of effective raising product is high, simultaneously by concentration sand, quartz sand and glass sand by certain weight ratio carry out with the use of, the quartzite slate prepared has good intensity, and gradation sense is obvious, and decorative pattern is more natural.When selecting the concentration sand of specific order number, quartz sand and glass sand, effect is better.
Further 100-200 order silica powder and 325-800 order silica powder are carried out collocation according to certain weight ratio to add, the two can performance complement in mixed system, effectively improves the intensity of quartzite slate; Adopt the unsaturated polyester that viscosity is suitable, each feed composition can be impelled to be uniformly dispersed at mixed system, and conglobation property is good, and while performance better plays, make the preparation technology of quartzite be easier to control, the quality of production is stablized; Primary colors powder is pressed certainweight accounting preparation mill base and toner compound, the decorative pattern lines that making can be made to obtain are more natural.
The preparation method of quartzite slate of the present invention, first cuts wet feed, then rolls, each component wet feed can be made more naturally to merge, effectively improve the stability of technique, and finished product has more gradation sense, when further control cutting screen cloth is of a size of 20-30mm, effect is better; Again after cutting, color is added in two steps, first sprinkle mill base, then spray toner compound, product decorative pattern lines can be made more natural.
Compared with prior art, the present invention has following beneficial effect:
Quartzite slate of the present invention, intensity is desirable, and gradation sense is good, has the texture of lithotome and beautiful surface luster, and because each material matching is reasonable, product processes is easy to control, and good article rate height can realize mass production.
The preparation method of quartzite slate of the present invention, stable processing technique, simply, effectively can improve the natural sense of product decorative pattern.
