The following describes a strengthened rock plate according to an embodiment of the present invention with reference to fig. 1 to 3, including a green brick 1 and a decorative layer 2 on the surface of the green brick 1, where the green brick 1 is composed of a post-processing region 11 and a non-processing region 12, and the post-processing region 11 is located around or in the middle of the green brick 1;
the post-processing region 11 is composed of a first toughness layer 111, a second toughness layer 112 and an intermediate layer 113, wherein the first toughness layer 111 is positioned at the top of the post-processing region 11, the second toughness layer 112 is positioned at the bottom of the post-processing region 11, and the intermediate layer 113 is positioned between the first toughness layer 111 and the second toughness layer 112;

It is worth to be noted that the fracture toughness characterization material is a quantitative index for measuring the toughness of the material, and the higher the fracture toughness of the material is, the stronger the crack propagation resistance is, the better the toughness is, and the less cracking is likely to occur.
The rock plate is often used as house mesa and panel, machining such as cutting wantonly, polishing, drilling, chamfer need be carried out, because the toughness of current rock plate under high strength is lower, can appear 30% -50% or even higher cutting fracture when carrying out machining, lead to the product qualification rate lower, seriously influence the later stage of product and use, though some rock plate enterprises make the rock plate have higher toughness and intensity through changing the rock plate raw materials at present, these rock plates often manufacturing cost is higher. In order to solve the problems, the technical scheme sets the area of the green brick 1 which needs to be mechanically cut as a post-processing area 11, and sets the area which does not need to be mechanically cut as a non-processing area 12, and because the non-processing area 12 does not need to be cut and is not easy to crack, the raw material of the non-processing area 12 only adopts the prior common raw material of the rock plate green brick, the non-processing area 12 prepared by the prior common raw material of the rock plate has certain fracture toughness and can meet the daily use of the rock plate, the post-processing area 11 is sequentially provided with a first tough layer 111, an intermediate layer 113 and a second tough layer 112 from top to bottom, because the fracture toughness of the first tough layer 111 and the fracture toughness of the second tough layer 112 are all greater than that of the intermediate layer 113, and the fracture toughness of the intermediate layer 113 is greater than or equal to that of the non-processing area 12, the fracture toughness of the whole post-processing area 11 is greater than that of the non-processing area 12, when mechanical cutting is carried out on the post-processing area 11, the post-processing area 11 is not easy to crack, and therefore the problem that the existing rock plate cracks easily when mechanical cutting is carried out is solved.
Because the fracture toughness of the rock plate is realized by adding some toughening raw materials capable of increasing fracture toughness, the more the addition amount of the toughening raw materials is, the higher the fracture toughness of the rock plate is, the less cracking is, but the price of the toughening raw materials capable of increasing fracture toughness is generally high, for example, the existing rock plate enterprises generally add zirconia into the rock plate to improve the fracture toughness of the rock plate, but the price of the zirconia is far higher than that of other rock plate raw materials, if the fracture toughness of each area of the whole rock plate is high, the needed toughening raw materials are very much, and the raw material cost of the rock plate can be greatly increased, therefore, the technical scheme carries out partition and layering arrangement on the rock plate brick blank, the existing common rock plate brick blank raw materials can be directly adopted in the non-processing area 12, so that the non-processing area 12 can meet the daily use of the rock plate, and some existing toughening raw materials which are easily obtained in the field are added into the rock plate raw materials of the post-processing area 11 (for example: zirconia) to improve the overall fracture toughness of the post-processing region 11, which not only can avoid the cracking of the post-processing region 11 during machining, but also can reduce the cost of raw materials. And this technical scheme carries out the layering to the post-processing region 11, because first obdurability layer 111 and the obdurability layer 112 are not retrained, relatively easy fracture, and intermediate level 113 is because retrained by first obdurability layer 111 and the obdurability layer 112, difficult fracture, consequently, set up the fracture toughness of first obdurability layer 111 and the fracture toughness of the obdurability layer 112 of second to be greater than the fracture toughness of intermediate level 113, intermediate level 113 can directly adopt current ordinary rock plate raw materials, or add in current ordinary rock plate raw materials few toughening raw materials (zirconia) alright, can guarantee to use fewest toughening raw materials (zirconia), and make the post-processing region 11 reach required fracture toughness, can further reduce the cost of raw materials.
