Abstract

The invention discloses reinforced light-reflecting heat-insulating polymer cement waterproof paint. The polymer cement waterproof paint is prepared from, by weight, 60-70 parts of cement-based polymer emulsion, 35-45 parts of inorganic powder, 0.42-0.51 part of reinforced fiber, 3.7-4.55 parts of auxiliary and 8-15 parts of water. The inorganic powder comprises 20-23 parts of Portland cement, 12-15 parts of light-reflecting quartz powder and 3-7 parts of glass bead light reflecting powder; the auxiliary comprises 1.2-1.3 parts of coalescing agent, 0.3-0.5 part of stabilizer, 1.8-2 parts of plasticizer, 0.15-0.3 part of dispersant, 0.2-0.3 part of defoaming agent and 0.05-0.15 part of preservative. A small amount of acrylic reinforced fiber is added, the anti-cracking performance of a waterproof paint coating is improved, the light-reflecting quartz powder and the glass bead light reflecting powder are used in combination to achieve the efficient light reflecting effect, and the light reflecting performance is greatly improved to achieve the purpose of reducing indoor temperature by reducing the temperature of a roof or a building surface.

Description

【Technical field】 [0001] The invention relates to the technical field of architectural waterproof coatings, in particular to an enhanced reflective heat-insulating polymer cement waterproof coating. 【Background technique】 [0002] Polymer cement waterproof coating not only has strong waterproof performance, but also has strong tensile performance. In the process of use, it can form a layer of impermeable film, effectively avoiding the phenomenon of water leakage and permeation, so it has been widely used in architectural decoration in recent years, not only in indoor decoration such as pools, kitchens, and roofs. Polymer cement waterproof coating will be used, and it can also be mixed with other mud and mortar materials for the outer layer of the building. [0003] At present, the function of polymer cement waterproof coating is relatively simple, with waterproof and adhesion performance, but the effect of heat insulation and reflection is low, and the thick coating at the ...
