Abstract

The invention discloses waterproof putty powder used in a low-temperature environment and a preparation process of the waterproof putty powder used in the low-temperature environment; the waterproof putty powder comprises 82 to 90% of a putty powder base material, 6 to 10% of an antifreeze agent and 4 to 8% of a heat insulating agent, wherein the antifreeze agent comprises the following componentsin parts by weight: 30 to 40 parts of propolis powder, 40 to 50 parts of sodium metasilicate pentahydrate, 6 to 12 parts of lithium magnesium silicate, 15 to 20 parts of calcium nitrite, 10 to 15 parts of cerium oxide, 4 to 8 parts of zinc chloride, and 1 to 5 parts of calcium lignosulfonate; the heat insulating agent comprises the following components in parts by weight: 40 to 50 parts of ceramic hollow microspheres, 8 to 10 parts of sepiolite fabric, 2 to 5 parts of aluminum borosilicate whisker, and 10 to 15 parts of silica aerogel. The putty powder produced by the invention can be normally constructed in the low-temperature environment which is below 5 DEG C, can automatically repair cracks in a putty structure, and further has excellent frost-crack resisting, waterproof and thermal insulation performance.

Description

technical field [0001] The invention belongs to the field of building materials, and also relates to a functional putty powder, in particular to a waterproof putty powder used in a low-temperature environment and a preparation process thereof. Background technique [0002] Putty powder is a decorative material for leveling the surface of the wall. It is applied on the primer or directly on the wall to remove the unevenness of the wall. The construction environment of traditional putty should not be lower than 5°C. When the temperature is too low, the exterior wall putty coating will be difficult to dry after scraping the putty, and the unevaporated water will freeze. After entering March, as the temperature rises, the ice begins to When it melts, the moisture seeps out of the wall, causing the putty to crack and peel, and when the moisture is completely dry, the putty will fall off. In addition, in the prior art, cement is mostly used as the binder of putty powder, which ha...
