Vitrified-microbead decorative thermal-insulation board

Abstract

The invention relates to a vitrified-microbead decorative thermal-insulation board, belonging to the technical field of architectural boards. The vitrified-microbead decorative thermal-insulation board is prepared from expanded vitrified microbeads, white lime, quicklime, cement, silica fume, gypsum, high-quality PP (polypropylene) fiber, waterproofing agent, rubber powder, fly ash and foaming agent in a certain ratio by a certain technique. The average dry apparent density of the product is 265kg / m<3>, the average heat conductivity coefficient is 0.058w / m.k, the average compressive strength is 0.67mpa, and the combustion performance is non-inflammable Grade A. The vitrified-microbead decorative thermal-insulation board has the function of fireproofing, and has the characteristics of light weight, thermal insulation, high dimensional stability, aging resistance, freeze thawing resistance, simple construction, beautiful appearance and the like. Besides, the invention reduces the pollution of flying dust due to use of powder in the construction process, saves the construction time by 50% in the aspect of construction cycle, greatly lowers the construction cost, and implements energy consumption saving in building construction in deed.

Description

technical field [0001] The invention relates to a building board, in particular to a vitrified microbead decorative heat preservation board capable of achieving heat insulation and decoration effects. Background technique [0002] In buildings, the heat loss of the external wall enclosure structure is relatively large, of which the wall accounts for the largest share. Therefore, the reform of building walls and the development of wall energy-saving technology are the most important links in building energy-saving technology. The development of external walls Insulation technology and energy-saving materials are the main ways to achieve building energy conservation. [0003] With the development of society, more and more buildings consume a large amount of non-renewable resources and energy; especially a large number of buildings with poor thermal insulation effect not only consume more energy for heating in winter and cooling in summer, but also Cause a lot of environmental...

Problems solved by technology

In recent years, vitrified microbeads have the best thermal insulation effect among the materials used. Various thermal insulation building materials with vitrified microbeads as the core material have appeared one after another, but many materials have not achieved the desired effect.

In the current thermal insulation market, among the inorganic thermal insulation materials whose fire protection level can meet the national requirements and local standards, most of them are slurry, the thickness is difficult to control during the construction process, the quality is difficult to guarantee, and the performance cannot meet the final requirements.

Although the fireproof performance of inorganic thermal insulation materials can be guaranteed, their defects such as high density, low strength, and poor water resistance limit their application fields.

[0006] Patent application number 2012101479508 announced "Vitrified microbead composite insulation board and its preparation method", which is made of vitrified microbeads, cement, calcium powder, latex powder, cellulose ether, water repellent, and polypropylene fiber. Although the thermal insulation board prepared by this method has a certain thermal insulation effect, it is not Class A flame retardant, and it is not convenient for mass promotion

[0007] Patent application number 201110107886.6 announced "a vitrified microsphere / fly ash composite external wall insulation board" which uses fly ash, expanded vitrified microspheres, rapid hardening sulphoaluminate cement, water glass, emulsified paraffin, It is made by mixing quartz sand, glass fiber, polycarboxylate superplasticizer, and redispersible latex powder. It has good fire prevention and heat preservation effects, but it has too much weight and high construction cost, so it is not suitable for mass promotion.
