Embodiment 2
[0043] Embodiment 2: The preparation method of the putty and the preparation method of the masterbatch are the same as in Example 1, but the components of the putty raw materials are respectively in parts by weight: 550 parts of base material, 230 parts of vitrified microbeads, and 50 parts of masterbatch , 550 parts of cement; the masterbatch is composed of the following raw materials in parts by weight: 25 parts of redispersible latex powder, 7 parts of hydroxypropyl methylcellulose, 0.7 part of starch ether, 1.2 parts of hydrophobic agent, and 0.7 part of water reducing agent , 2.3 parts of polypropylene staple fiber, 2.5 parts of palm fiber.
[0044] Preferably, the palm fiber is arc-shaped.
Embodiment 3
[0045] Embodiment 3: The preparation method of the putty and the preparation method of the masterbatch are the same as in Example 1, but the components of the putty raw materials are respectively in parts by weight: 400 parts of base material, 200 parts of vitrified microbeads, and 30 parts of masterbatch , 400 parts of cement; the masterbatch is made up of the following raw materials in parts by weight: each component of the masterbatch is in parts by weight: 20 parts of redispersible latex powder, 4 parts of hydroxypropyl methylcellulose, 0.5 parts of starch ether, 1 part of hydrophobic agent, 0.5 parts of water reducing agent, 2 parts of polypropylene short fiber, 2 parts of palm fiber.
[0046] Preferably, the palm fiber is arc-shaped.
[0047] In order to shape the palm fiber into an arc, a method such as Figure 2-Figure 5 A kind of external wall thermal insulation putty powder preparation equipment is shown, it comprises frame, and described frame comprises the side pl...
