Lightweight porous sound-absorbing insulation mortar and preparation method thereof
The present invention discloses a lightweight porous sound-absorbing insulation mortar, which is characterized being prepared from the following raw materials by weight: 40-45 parts of Portland cement, 27-30 parts of glass beads, 7-9 parts of honeycomb briquette slag, 3-5 parts of chopped glass fiber, 3-4 parts of active alumina micro powder, 5-7 parts of scoria, 2-3 parts of silicon carbide, 4.5-6.5 parts of fluff pulp, 2.5-3.5 parts of pre-gelatinized starch, 0.2-0.3 part of polyphosphates ammonium, and 8-10 parts of a synergist. The glass beads, the scoria, the honeycomb briquette slag, the silicon carbide and other materials are used, insulation properties are good, the lightweight porous sound-absorbing insulation mortar has a wealth of pores, by mixing with cement, under the premise of a large number of pores, the product has ideal waterproofing effect and good sound-absorbing effect; by adding of the polyphosphoester and other fire retardant ingredients, and y cooperation of adding of the synergist, the product's flame resistance is further enhanced, meanwhile the product's anti-crack resistance and high temperature resistant performance can be enhanced; and the lightweight porous sound-absorbing insulation mortar is lightweight, porous, resource-conservation, and worthy of promotion.
