The toners of this example are two, one black and one yellow; then preparing black colored particles and yellow colored particles according to the colored particle raw materials; and then mixing the black colored particles and the yellow colored particles in a dispersion protective agent respectively, filtering and shearing the mixture into colored particles with different colors and particle sizes, which are wrapped by the protective agent, and then mixing the colored particles according to the proportion to obtain the finish coating.

The protective agent of this embodiment can cover the whole colored particles and ensure no adhesion between the particles, so as to satisfy the application requirements, and the other embodiments are also the same.

The inorganic powder in this embodiment may be made of the following materials, for example: quartz sand, river sand, natural colored sand, and the like.

The coating amount per unit area of the facing coating of the utility model is 0.05-0.8kg/m²Preferably 0.1 to 0.6kg/m²。

The unit area coating amount of the top-coat coating of the utility model is 0.05-0.4kg/m²。

The area water absorption rate of the rock wool splice plate is measured according to the JGT287-2013 standard to be 165g/m². The volume water absorption of the rock wool splice plate is measured to be 1.06 percent according to the GB/T5486-2008 standard.

And (3) testing mechanical properties: the rock wool splice plate obtained according to the preparation method of the embodiment and the plate obtained by simply splicing the rock wool strips in the comparative example (except for the rock wool strips in the interior and the perforated and spliced reinforcing ribs, the treatment of the back coating is the same as that of the embodiment) are made into a 120cm multiplied by 60cm multiplied by 20cm pattern, the compressive strength and the flexural strength of the pattern are detected by a universal mechanical tester, the specific steps refer to GB/T17657-1999, and all the results show that the splice plate prepared according to the embodiment of the utility model has the compressive strength of 7.05MPa and the flexural strength of 3.15MPa, and the splice plate prepared according to the comparative example has the compressive strength of 2.15MPa and the flexural strength of 1.12 MPa; obviously the utility model discloses the rock wool splice plate of mode preparation's intensity is higher than the splice plate's of comparative example traditional mode preparation intensity far away.
