Embodiment 1

[0025] The invention relates to an external wall thermal insulation, waterproof and anti-cracking putty powder. The preparation method of the ultraviolet absorber is to mix extracts of polygonatum polygonatum and sophora japonica.

[0026] The preparation method of the polygonatum polygonatum and pagoda japonica mixed extract is as follows: drying equal weight polygonatum polygonatum and pagoda japonica to constant weight, crushing them through 40 meshes, adding 70% ethanol to the polygonatum polygonatum and pagoda japonica mixed powder, and ultrasonically extracting at 60°C 20min, ultrasonically filtered and ultrasonically extracted twice, and the two filtrates were combined to obtain the product.

[0027] In the method for preparing the mixed extract of Polygonatum polygonatum and Sophora japonica, the solid-to-liquid ratio of Polygonatum polygonatum and Sophora japonica mixed powder to ethanol is 1:20.

Abstract

The invention relates to an exterior wall insulation waterproof crack-resistant putty powder, which contains the following raw materials (by weight): 100-200 parts of white cement, 60-80 parts of fine quartz sand, 30-50 parts of powdered steatile, 80-100 parts of calcium bicarbonate powder, 20-30 parts of Chinese medical stone powder, 1-2 parts of hydroxypropyl methylcellulose, 3-5 parts of dispersible latex powder, 1-3 parts of adhesive powder for putty, 1-2 parts of an antibacterial mildew inhibitor, 6-8 parts of hollow glass beads and 0.5-1 part of a UV-absorber. The exterior wall putty powder has long storage stable period, good construction performance, excellent bonding strength, scratch resistance, water resistance, thermal insulation property, ultraviolet absorption and cracking resistance.

Description

technical field [0001] The invention relates to the technical field of exterior wall putty, in particular to an exterior wall thermal insulation, waterproof and anti-cracking putty powder. Background technique [0002] Putty powder is a kind of building decoration material, a kind of base material used for wall repair and leveling, and lays a good foundation for the next decoration. Putty is divided into two kinds: putty inside wall and putty on exterior wall. External wall putty requires good wind and sun resistance and high strength. During the construction of putty powder in the prior art, the base layer under the putty layer is generally a cement mortar layer. Due to the high rigidity of the cement mortar layer, more or less microscopic cracks are often produced under the effects of hardening shrinkage, alternating wet and dry changes, or changes in temperature difference. Cracks, resulting in cracking of the putty layer and paint layer. [0003] At present, the existi...
