Thermal insulation mortar powder and manufacturing method thereof

Abstract

The invention aims to provide thermal insulation mortar powder with low cost and good insulation effect and a manufacturing method of the mortar powder. The thermal insulation mortar powder comprises the following components in parts by weight: 400-500 parts of Portland cement, 30-70 parts of glazed hollow bead, 50-100 parts of saw dust, 10-20 parts of rice husk, and 5-10 parts of water reducing agent. The manufacturing method of the mortar powder comprises the following steps: A, putting saw dust and rice husk into a hopper to be mixed and stirred, and shaking the hopper during the mixing process to enable the saw dust to enter the rice husk; B, mixing Portland cement, glazed hollow bead and the reducing agent, and at least stirring the mixture for 20 min; C, adding the rice husk filled with the saw dust into the mixture of Portland cement, glazed hollow bead and reducing agent, stirring the rice husk and the mixture for at least 15 min, and obtaining the thermal insulation mortar powder. In the invention, the saw dust is filled into the rice husk, so that the rice husk is supported definitely. In this way, when the rice husk is mixed with the Portland cement, the rice husk and the saw dust inside can insulate heat, and achieve the purpose of thermal insulation with the glazed hollow bead.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation building materials, and in particular relates to a thermal insulation mortar powder and a manufacturing method thereof. Background technique [0002] Insulation mortar powder is a kind of ready-mixed dry powder mortar made of various lightweight materials as aggregates, cement as cementitious material, mixed with some modified additives, and mixed by the production enterprise.
