Abstract

The invention discloses waterproof and heat insulation dry powder mortar. The dry powder mortar is prepared from the following components in percentage by weight: 45-55% of white cement, 20-30% of quartz sand, 6-8% of a floating bead, 10-15% of ultrafine wollastonite powder, 1-3% of redispersible latex powder, 0.3-0.5% of methylcellulose ether, 0.4-0.8% of an advanced fatty acid water repellentand0.5-1% of a polycarboxylic acid water reducer. According to the waterproof and heat insulation dry powder mortar, the construction is easy, the functions of high adhesion, heat insulation, water resistance, durable service and the like are achieved, the white decoration action is further achieved, environmental protection is achieved, and energy conservation and the safety are achieved.

Description

technical field [0001] The invention relates to the technical field of building materials and building construction, in particular to a waterproof and heat-insulating dry powder mortar. Background technique [0002] In recent years, the state has advocated the principles and policies of "circular economy", "building a conservation society" and "sustainable development". The development goals in architectural design are also towards high efficiency, saving energy and resources, harmless, and pollution-free. The construction of green ecological buildings with good waterproof and heat insulation and energy saving has become more and more popular. [0003] For waterproof and heat insulation, although there are building materials such as heat-insulating and waterproof coatings or mortars on the market, there are few building materials that integrate white decoration and waterproof and heat-insulating functions, which can reduce the decoration process. [0004] Therefore, those ...
