Embodiment 1
[0026] It is prepared from the following raw materials according to the ratio of parts by weight, 42.5R ordinary silicon cement: 400 mesh lime calcium powder: 40-70 mesh sand: lignin: polypropylene short fiber: silica fume: composite resin rubber powder = 360:102 :600:4:1:43:26.
[0027] The preparation process comprises the following steps:
[0028] Arrange the screening machine at the lower part of the mixing tower, lift the screened sand of different grades to the top of the tower, and send it to each sand bin;
[0029] After the small amount of lignin and polypropylene short fiber are measured separately by the platform scale, they are pre-mixed with the above-mentioned other mixtures through a small mixer, and then enter the large mixer after pre-mixing. The mixing time is 120-180 seconds;
[0030] The uniformly mixed mortar is packaged in bags to obtain a finished product.
Embodiment 2
[0032] It is prepared from the following raw materials according to the ratio of parts by weight, 42.5R ordinary silicon cement: 400 mesh lime calcium powder: 40-70 mesh sand: lignin: polypropylene short fiber: silica fume: composite resin rubber powder = 300:80 : 550: 3: 1: 30: 22; its preparation process is the same as in Example 1.
Embodiment 3
[0034] It is prepared from the following raw materials according to the ratio of parts by weight, 42.5R ordinary silicon cement: 400 mesh lime calcium powder: 40-70 mesh sand: lignin: polypropylene short fiber: silica fume: composite resin rubber powder = 420:120 : 700: 8: 2: 60: 38; its preparation process is the same as in Example 1.
