Abstract
The invention relates to a method for preparation of a heat preservation wall material from pile mud. The method comprises the technological steps of: 1) storing the pile mud to a moisture content of 30%-40%; 2) adding vitrified microspheres or perlite, and stirring them evenly, then conducting standing; 3) making the mixture into billets of various shapes and sizes; and 4) drying the billets, then sending the billets into a kiln to undergo firing, thus finally forming the heat preservation wall material. The method for preparation of the heat preservation wall material from pile mud has the advantages of simple process, low cost, full use of waste materials, environmental pollution reduction and the like. And the prepared heat preservation wall material the characteristics of good thermal insulation effect and difficult cracking, etc.
