Preparation method of lightweight thermal insulation material
The invention provides a preparation method of a lightweight thermal insulation material. The lightweight thermal insulation material is prepared from the steps of according to a formula, getting such materials as 10-15 parts of volcanic ash, 5-7 parts of polyvinyl alcohol, 30-40 parts of water, 20-30 parts of white latex, 1-3 parts of flexibilizer and 0.3-1 part of polypropylene fibers ready, boiling water and then adding the polyvinyl alcohol, continuing heating and stirring to dissolve the polyvinyl alcohol until no particle exists, next, adding the volcanic ash, the white latex, the flexibilizer and the polypropylene fibers to the mixed liquid in the step 2, stirring and mixing evenly, and standing for 5-10 minutes, thereby obtaining the lightweight thermal insulation material for spraying. The lightweight thermal insulation material prepared by use of the preparation method is remarkable in thermal insulation effect, low in specific gravity, low in cost, and good in tenacity; in addition, due to the added white latex, the lightweight thermal insulation material has relatively high bonding strength and meets the requirements of exterior wall coating.
