Abstract

Disclosed mixed thermal-insulation mortar with good performances and high construction efficiency is characterized by being prepared from the following raw materials in parts by weight: 25-29 parts of hydraulic silicate cement, 0.5-0.7 part of polylactic acid, 10-13 parts of hydrated lime, 0.2-0.4 part of starch ether, 24-28 parts of expanded vitrified microsphere, 16-19 parts of river sand, 3-5 parts of xanthan gum, 0.7-1 part of sodium dinaphthylmethanedisulfonate, 2-3 parts of expanded graphite, 1-2 parts of sodium alginate, and 8-10 parts of a synergist. By adding sodium dinaphthylmethanedisulfonate and expanded graphite, the prepared dry powder possesses good dispersibility and lubricity, is added with water and stirred when being used, is good in fluidity, does not destroy vitrified microsphere, and guarantees thermal-insulation effect. Also, by adding the synergist prepared through a special technology, the product prevents water, moisture and worm damage, and because of the internally-contained water reducer, the cement usage amount is reduced. The product is good in performances, possesses good construction performance and helps to improve the construction efficiency.
