Slope protection material and preparation method thereof

The invention relates to the field of permeable bricks, in particular to a preparation technology of a high imitation stone permeable brick, and the prepared high imitation stone permeable brick. Thepreparation technology of the high imitation stone permeable brick is provided for solving the problem that the situation that surface layer patterns of an existing imitated stone permeable brick areevenly distributed violates the natural property of stone. The preparation technology comprises the following steps that a surface layer solid raw material is placed in a stirring machine for evenly mixing, and then placed in a pelletizer to be pelletized at the speed of 20-40 r/min while water spraying to obtain a surface layer mixture A1; by parity of reasoning, surface layer mixtures A2, A3,..., and An are obtained; and the surface layer mixtures A2, A3, ..., and An are placed in the stirring machine for stirring at 2-10 r/min for 5-30s, and a surface layer mixture A which is not evenly mixed is obtained; a bottom layer raw material is placed in the stirring machine for even stirring to obtain a bottom layer mixture B; forming is conducted; and maintenance is conducted. According to thepreparation technology of the high imitation stone permeable brick, two or more groups of surface layer mixtures containing at least two colors are adopted for slow mixing to form the high imitationstone permeable brick, different colors are distributed randomly in fabric, spots or streaks of the same color in the local range occur, and the permeable brick surface layer presents the stone imitation effect of uneven distribution is achieved.

The invention relates to the field of water-permeable bricks and particularly relates to a process for preparing high-stone-imitated water-permeable bricks and the prepared high-stone-imitated water-permeable bricks. The process and the high-stone-imitated water-permeable bricks are used for solving the problem that surface layer patterns of the existing stone-imitated water-permeable bricks are uniformly distributed and are disobeyed with natural properties of stones. The process for preparing the high-stone-imitated water-permeable bricks, provided by the invention, comprises the following steps: preparing of a surface layer mixture: uniformly stirring surface layer raw materials in a stirrer at a high speed of 100r/min to 400r/min, so as to obtain a surface layer mixture A1; by parity of reasoning, obtaining surface layer mixtures A2, A3, ... and An; stirring the surface layer mixtures A1, A2, ... and An in a stirrer for 5 to 30 seconds at a low speed of 2r/min to 10r/min, so as toobtain a non-uniform-mixed surface layer mixture A; preparing of a bottom layer mixture: uniformly stirring bottom layer raw materials in a stirrer, so as to obtain a bottom layer mixture B; molding;and curing. According to the process and the high-stone-imitated water-permeable bricks, the high-stone-imitated water-permeable bricks are prepared through slowly mixing two or more groups of surfacelayer mixtures at least containing two kinds of different colors, so that the different colors are randomly distributed in facing materials of the water-permeable bricks, and surface layers of the water-permeable bricks present a disperse and non-uniform-distributed stone-imitated effect.
