Problems solved by technology

Generally speaking, inorganic materials can generally meet the fire protection requirements of B1 or A, but their density per unit volume is relatively high, and their thermal conductivity is relatively high. Compared with organic thermal insulation materials, their thermal insulation and energy saving effects are worse
Especially in the colder north, the construction thickness of less than 10 cm is difficult to meet the requirements of building energy conservation codes

Embodiment 1

[0039] In this example, four natural mineral materials are used: attapulgite with layered chain structure, layered montmorillonite, layered kaolinite, and fibrous wollastonite, and calcined high Insulation composite materials prepared from Lingshi inorganic materials, and then pressed external wall insulation boards in this example. The specific preparation is as follows:

[0040] Material preparation: 10 kg of 1-2 cm attapulgite, 10 kg of kaolin, 5 kg of montmorillonite, and 7 kg of wollastonite. One WX1 ultra-fine swirl mill from Shenzhen Weixiong Machinery Equipment Co., Ltd., one WG3 high-pressure roller mill from Shenzhen Weixiong Machinery Equipment Co., Ltd., a spray dryer from Sifang Chemical Equipment Company, and a nano The processing device is an expansion tank made by South China University of Technology, and an electrostatic composite device made by South China University of Technology.

[0041] Preparation of external wall insulation board:

[0042] 1. Take 1 ...

Embodiment 2

[0059] The natural mineral material used in this example is the same as that in Example 1, except that the components are different, and the inorganic material with infrared reflection properties uses zircon, and the rest of the equipment and conditions are basically the same as in Example 1. The specific preparation is as follows:

[0060] 1. Take 1 kg of wollastonite and 2 kg of attapulgite and process them with high-pressure roller milling.

[0061] 2. Mix the processed wollastonite and attapulgite with water to form a slurry with a solid content of 65%, add 0.5% sodium pyrophosphate and 5% acetone and put it into a storage tank.

[0062] 3. Pump the above-mentioned slurry with a solid content of 65% into an ultra-fine swirl mill for ultra-fine treatment, and then put it into a storage tank.

[0063] 4. Pump out the slurry from the storage tank and then enter the nano treatment device for 20 minutes, and then put it into the storage tank.

[0064] 5. Pump the slurry that ...

Abstract

The invention discloses an external wall insulation board and a preparation method thereof. The external wall insulation board is pressed and formed by using an insulation composite material through adry powder pressing forming device; the insulation composite material is composed of a natural mineral material and an inorganic material with infrared reflection characteristics, and after the natural mineral material forms a composite material with a nano microporous structure, the composite material wraps the surface of the inorganic material; the natural mineral material comprises at least one of attapulgite, montmorillonite, kaolinite and wollastonite; the inorganic material comprises at least one of rutile, calcined kaolinite and zircon. The external wall insulation board is prepared through pressing by using the insulation composite material comprising the natural mineral material and the inorganic material with the infrared reflection characteristics, and the natural mineral material and the inorganic material have high flame retardancy, good high temperature resistance performance and good heat preservation effect; the board is non-toxic, safe and environmentally friendly. Inaddition, the external wall insulation board does not need an external steel wire mesh, and is simple and convenient to use.

Description

technical field [0001] The present application relates to the field of thermal insulation materials, in particular to an external wall thermal insulation board and a preparation method thereof. Background technique [0002] The core of energy-saving buildings is to reduce building energy consumption and building energy consumption, and to improve energy efficiency in buildings and in use. At the same time, building energy conservation must be based on the premise of not affecting people's comfort, that is, the room temperature should not be lower than 18 degrees Celsius in winter and not higher than 26 degrees Celsius in summer. Building exterior wall insulation board is one of the most important methods to realize energy-saving buildings. [0003] The current external wall thermal insulation materials are mainly divided into three categories: one is thermoplastic thermal insulation materials, for example, EPS thin plaster external wall thermal insulation system is the most...
