Embodiment Construction
[0043] The present invention is described in detail below in conjunction with accompanying drawing:
[0044] A kind of inorganic mineral fiber spray rock mud, composition material and weight ratio are as follows:
[0045] Inorganic mineral fiber 60%; fiber sepiolite 20%; hydroxypropyl methylcellulose (HPMC) 0.5%; redispersible latex powder 2%; water repellent: 0.5%; Portland cement 10%;
[0046] The inorganic mineral fiber has a melting point of 1200°C and a thermal conductivity of 0.035W / m.k.
[0047] The fiber sepiolite: longitudinal fiber, melting point 1200°C, thermal conductivity: 0.038-0.046W / m.k.
[0048]The hydroxypropyl methylcellulose (HPMC): 80 mesh to 120 mesh, model number: 60YTJ100000 to 60YTJ200000.
[0049] The average particle size (um) of the redispersible latex powder is 85±15.
[0050] The water-repellent agent: fineness: 150 μm; sieve residue ≤ 10%; active substance content: ≥ 65%
[0051] The strength grade of the Portland cement is 425#.
