Embodiment Construction

[0019] A kind of thermal insulation mortar, preparation method is:

[0020] (1) Take materials according to the following ratio:

[0021] Activated carbon 0.2, slag 2, stearic acid 0.2, cement 15, polystyrene foam particles 2, latex powder 6, vitrified beads 10, mullite 30, polypropylene chopped fiber 2.5, styrene-acrylic emulsion 2, methyl Cellulose 2, sulfonated material 0.4, lignin superplasticizer 2;

[0022] (2) Put the white mud of papermaking waste into the pulping tank to make a slurry with a solid content of 20%; heat the slurry to 50°C, mix it with corn stalks, add sodium lauryl sulfate, and stir After 80 minutes, dry and extrude into blocks to obtain block materials for later use; inject a hydrochloric acid solution with a concentration of 0.5% in the reaction kettle until the block materials are soaked, and after 60 minutes, keep the pressure at 0.4 MPa for 2 hours to obtain straw hydrolyzate. The pH of the straw hydrolyzate was adjusted to 6.0 with CaO to obtain...

Abstract

The invention discloses thermal-insulation mortar. Proper amounts of water and activated carbon are added after slag is crushed, ultrasonic dispersion is performed, then stearic acid is added, the mixture is stirred uniformly and dried, the dried mixture is mixed with a sulfonation material and the rest raw materials, a proper amount of water is added, the mixture is stirred uniformly, and thus the thermal-insulation mortar is obtained. The thermal-insulation mortar can well resist cracking due to addition of chopped polypropylene fibers and the sulfonation material, and the thermal-insulation effect and impact resistance of the thermal-insulation mortar are improved by the aid of the slag supporting activated carbon.

Description

technical field [0001] The invention relates to the field of thermal insulation mortar, in particular to thermal insulation mortar. Background technique [0002] Insulation mortar is a kind of pre-mixed dry powder mortar made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed by the production enterprise. A building material used to construct the thermal insulation layer of the building surface. Inorganic thermal insulation mortar (vitrified microbead fireproof thermal insulation mortar, composite silicate thermal insulation mortar) is a new type of thermal insulation and energy-saving mortar material used for painting the interior and exterior walls of buildings. Replacement) as light aggregate, add dry powder mortar composed of cementitious material, anti-cracking additives and other fillers. It has the characteristics of energy saving and waste utilization, thermal insulation, fire prevention and freezing resistance,...
