Problems solved by technology

However, the price of the composite thermal insulation mortar proposed in this paper is relatively high, the construction is complicated, and it is difficult to solve the problems of cracks and hollowing after construction.
The function is relatively single, and it cannot meet the requirements of modern buildings for other building properties of thermal insulation mortar, such as sound insulation, environmental protection and light weight, etc.

Embodiment Construction

[0017] Provide following embodiment below in conjunction with content of the present invention:

[0018] Polystyrene foam particle insulation mortar, weigh various raw materials according to the formula ratio, first add siloxane emulsion to polystyrene foam particles, stir evenly, dry the mixture, then add micro silica fume, Portland cement, Fly ash, quartz sand and polypropylene fiber are fully stirred and evenly formed into a product, which is then bagged. According to the needs of engineering applications, the required properties can be obtained by adjusting the inventive formula. In specific implementation process, each component weight percent is:

[0019]

[0020] The above components are prepared according to the aforementioned process to obtain dry powder of polystyrene foam particle insulation mortar, add appropriate amount of water to make the consistency of the mortar mixture reach 80mm, and form samples according to the standard requirements. The consistency, ...

Abstract

The heat insulating foamed polystyrene particle mortar used in building engineering consists of portland cement 40-45 wt%, flyash 3-6 wt%, fine silica powder 0-3 wt%, foamed polystyrene particle 1.3-2.8 wt%, polypropylene fiber 0.1-0.2 wt%, quartzite 42-47 wt% and water-thinned silane / siloxane emulsion 5-8 wt%. The present invention has light bulk weight, dry density 300-480 kg / cu m; good heat insulating and sound isolating performance, and heat conducting coefficient 0.07-0.13 W / m.k. The present invention utilizes partial flyash to replace cement and the product has no environment pollution.

Description

technical field [0001] The invention relates to a building mortar, in particular to a polystyrene foam particle thermal insulation mortar. It is used in the technical field of building materials engineering. Background technique [0002] At present, the country is vigorously developing and promoting environmental protection and energy-saving building structures. To implement building energy conservation, it is necessary to greatly improve the thermal performance of the outer envelope structure, especially the outer wall. However, it is unrealistic to generally adopt composite energy-saving wall materials in the Yangtze River Basin and southern regions of my country in the short term. Moreover, the materials used to build these insulating lightweight walls mostly use ordinary cement or mixed masonry mortar, and the apparent density of this type of mortar is generally 1600-1800kg / m 3 , the thermal conductivity is 0.8-1.0W / (m K), and the apparent density of lightweight insul...
