A kind of preparation method of thermal insulation and humidity control plaster mortar

Abstract

The present invention discloses a heat-insulation humidity-controlling surface mortar production method. A purpose of the present invention is to provide a heat-insulation humidity-controlling surface mortar production method. The method is characterized in that the raw materials comprise, by weight, (1) 10-20 parts of xylem fibers, (2) 20-40 parts of sepiolite, (3) 40-80 parts of expanded pearlite, (4) 2-5 parts of redispersible latex powder, (5) 0-3 parts of polypropylene fibers, and (6) 90-110 parts of cement; and the preparation method comprises: A, mixing the raw materials (1) and (2) according to ratio, stirring for 2 min, adding the raw material (3), and stirring for 1-5 min at a stirring speed of 310 rotation / min to prepare the mixed material; and B, adding the mixed material obtained in the step A, and the raw materials (4), (5) and (6) into a mortar stirrer to stir, adding water, and blending the slurry to achieve the mortar consistence of 60-80 mm. The heat-insulation humidity-controlling surface mortar production method is mainly used for production of the heat-insulation humidity-controlling surface mortar.

Description

technical field [0001] The invention relates to a preparation method of mortar, in particular to a preparation method of thermal insulation and humidity control plaster mortar. Background technique [0002] Air humidity is an important environmental parameter that is closely related to people's life and production, and it has attracted people's attention day by day. Excessive humidity in the air can cause discomfort such as dampness and chest tightness, induce arthritis and other diseases, cause metal surface corrosion, lead to a decrease in electrical insulation performance, promote the proliferation and development of various mold viruses, and affect food processing and preservation. It will affect the production and quality of mechanical parts products. However, if the air temperature is too low, it will cause skin allergies, dry eyes and nose, cause respiratory infection and asthma and other diseases to invade, and also cause static electricity. [0003] The plastering...

AI Technical Summary

Problems solved by technology

[0004] Lignocellulite, sepiolite and expanded perlite are three inorganic mesoporous materials, which have the characteristics of light weight, porous and hydrophilic, and these three materials have been widely used as adsorbents in textile, chemical, pharmaceutical, construction and other industries. We have been studying to improve the adsorption properties of these three materials, but when these three materials act alone, we need to add a variety of admixtures to achieve the desired effect

[0005] In order to achieve the function of thermal insulation and humidity control, the existing thermal insulation and humidity control mortar needs to add a variety of admixtures to achieve the effect, and the amount of these admixtures is not very large. If the mixing is not uniform, the expected effect will not be achieved. Stirring increases difficulty, which is not conducive to promotion as a mortar for improving indoor air quality
