Problems solved by technology

[0003] The thin-plaster external thermal insulation system is being paid more and more attention by people. As one of the important parts of the external thermal insulation system, the thin-plaster external thermal insulation plastering mortar is being continuously developed and developed, but due to the technical Due to the limitations of conditions and conditions, the plastering mortars currently on the market have poor water and crack resistance, rough surfaces, and need to be protected (through waterproof coatings and pasted bricks). Not only the cost is high, the construction period is long, but also There are quality and safety hazards

Abstract

The invention provides a white surface mortar compound which comprises the following components of parts by weight: 400 to 600pbw of white cement, 50 to 100pbw of semi-water gypsum, 50 to 100pbw of calcium hydroxide, 200 to 400pbw of modified fiber light calcium, 30 to 50pbw of latex powder which can be dispersed again, 2 to 4pbw of cellulose ether, 1 to 3pbw calcium chloride, 1 to 3pbw of calcium formate, 1 to 3pbw of aluminum potassium sulfate, 1 to 5pbw of polypropylene fiber and 250pbw of water. The surface mortar compound of the invention can be hydrated with cement and other components to form fine, dense and good finish surface to be applied for painting a wall body with different color surfaces, and the cost is reduced while the construction efficiency is enhanced. The compound is particularly applicable to an insulation system of the external wall of a civil building and an office building, which is economic and can be used as the surface mortar and internal dope of other wall bodies.

Description

technical field [0001] The invention relates to an expanded polystyrene board plastering mortar composition for external thermal insulation of white exterior walls. Background technique [0002] With the continuous development and progress of human society and the continuous economic growth, energy conservation is important to the sustainable development of human beings, and its significance is to be highlighted. People are constantly exploring and have achieved gratifying results. In energy consumption, the proportion of building energy consumption is about 30% to 40%. If effective energy-saving measures are taken, especially thermal insulation treatment for enclosure structures such as external walls, it can not only improve people's office and living Comfort, but also can save 30% to 50% of the power consumption due to the use of air conditioners, and the reduction of energy consumption reduces CO 2 emissions and waste of non-renewable resources. [0003] The thin-plast...
