Production method and application of pitchstone expansion vitrified micro-bead energy storage material

Abstract

The invention discloses a production method and application of a pitchstone expansion vitrified micro-bead energy storage material, belonging to the field of building thermal-insulation temperature-adaptable materials. In the existing thermal-insulation energy saving building materials, expanded polystyrene boards and extruded polystyrene boards as represented by thermal-insulation materials are difficult to satisfy the 65% energy saving requirement, and have the disadvantages of short service life, bad flame resistance and the like. The pitchstone expansion vitrified micro-bead energy storage material disclosed herein overcomes the disadvantages of the material in the prior art, and achieves the following advantages: 1, long service life: the material has the same service life with the building body; 2, good flame resistance: the material achieves the grade-A standard required by GB8621-2006; and 3, good weather resistance: the number of freeze-thaw cycles of the material is 50. Simultaneously, the material has a temperature adjustment function, when the indoor ambient temperature in the daytime is too high, the material can absorb heat in the environment, and when the indoor ambient temperature in the night is low, the material can release heat to the environment, thus the indoor temperature fluctuation is controlled, the use of the air-conditioners and heating systems is reduced, and the energy is saved. The material can be widely applied in building wall, the thermal insulation projects of wall surface, roof, and floor, and the like.

Description

1. Technical Field [0001] The turpentine expanded vitrified microsphere energy storage material belongs to the field of building thermal insulation and temperature adjustment materials, and is mainly used in building energy-saving walls, floors, and roofs. 2. Background technology [0002] 10 billion m in our country 2 Among the urban and rural buildings, only 320 million m 2 Of urban houses can be called energy-efficient buildings. Over 2 billion m2 completed annually nationwide 2 In the building, only less than 100 million m 2 Buildings are energy-efficient buildings, accounting for only about 3%. The heating or cooling energy consumption per square meter of buildings in my country is about three times that of developed countries. The national building energy consumption has accounted for 27.5% of the country's total energy consumption. my country is currently building high-energy-consuming buildings on an unprecedented scale. [0003] With the continuous growth of social dema...

Problems solved by technology

[0025] 3) Poor air permeability, almost impermeable, if the temperature difference between the two sides of the board is large, it is easy to condense when the temperature is high;

[0036] 1) Due to the nature of the board itself, its strength is not high, and its load-bearing capacity is low, so it needs to be strengthened when veneering bricks;

[0037] 2) Compared with the high water absorption of XPS board, if there is leakage, the board is easy to deteriorate and the heat preservation effect will be reduced

[0040] 5) The reinforcement mesh lacks due durability, and there is a risk of corrosion whether it is a glass fiber mesh cloth or a steel wire mesh

The second is that the burning is hidden in the completed decorative wall. After the spark ignites the insulation layer, it burns in the interlayer. From the outside, only cracks or unsealed gaps can be seen to emit smoke, but it is not known where and where the fire is burning. position, missed the best firefighting opportunity

[0045] For this reason, on September 25, 2009, the Ministry of Public Security and the Ministry of Housing and Urban-Rural Development jointly issued the document No. 46 of Gongtongzi [2009] on the issuance of the "Interim Provisions on Fire Protection of Civil Building External Thermal Insulation Systems and External Wall Decoration" , the document clearly stipulates that if the height of civil buildings is greater than or equal to 50 meters, the combustion performance of its thermal insulation materials shall be Class A, and if the height is greater than or equal to 24 meters, the combustion performance of its thermal insulation materials shall be Class A or B1, and B1 When using grade insulation materials, horizontal fire barriers should be set up for every two layers (the above materials are all organic materials, and their combustion performance can only reach B1 grade at most, and cannot reach A grade)

[0046] The release of this document also marks that the existing old wall insulation materials and technologies have come to an end, and can no longer meet the national security requirements. For the strong market demand, new alternatives that can meet the national security requirements The spring of wall energy-saving and thermal insulation materials is coming
