Problems solved by technology

[0002] The energy consumption of buildings in our country is very huge. The important reason is that the heat transfer coefficient of the building maintenance structure is relatively large and the insulation effect is poor. Therefore, it is extremely necessary to develop a new type of wall insulation material.

Embodiment Construction

[0017] Further illustrate the present invention in conjunction with embodiment and accompanying drawing, the present invention polyphenylene particle, cement, water, fly ash, redispersible latex powder, hollow fiber, hydroxypropyl methyl cellulose in the thermal insulation slurry of unit cubic meter , The mass ratio of the hydrophobic powder is 1.000:20.526:12.1582.947:0.263:0.089:0.221:0.263. The preparation of insulation board specimens is mainly carried out with mortar mixer to prepare 1m 3 For example, the insulation slurry, such as figure 1 As shown, the steps are as follows:

[0018] 1) Pour 28kg of fly ash and 195kg of cement into the mixer, add water and stir for 1 minute to make it fully mixed;

[0019] 2) Add 2.5kg of redispersible latex powder, 0.85kg of hollow fiber, 2.5kg of hydrophobic powder, and 2.1kg of hydroxypropyl methylcellulose to the mixture of the above 1), and stir for 30 seconds, of which hydroxypropylmethylcellulose The ingredients should be stirr...

Abstract

The invention relates to preparation of a fiber-reinforced composite thermal-insulation board, belonging to the technical field of thermal-insulation heat-barrier materials. The fiber-reinforced composite thermal-insulation board is mainly characterized in that the thermal-insulation slurry in unit cubic meter comprises the following components in parts by mass: 1.000 part of polyphenyl granule, 20.526 parts of cement, 12.158 parts of water, 2.947 parts of fly ash, 0.263 part of redispersible latex powder, 0.089 part of hollow fiber, 0.221 part of hydroxypropyl methylcellulose and 0.263 part of hydrophobic powder. The performance indexes satisfy or exceed the requirements in Composite Thermal-insulation Board Outer Wall Outer Thermal-insulation System Application Technical Regulations. The fiber-reinforced composite thermal-insulation board can achieve excellent performance effects; and the preparation technique of the fiber-reinforced composite thermal-insulation board is simple and easy to implement and convenient to operate.

Description

technical field [0001] The invention relates to the preparation of a fiber-reinforced composite material insulation board, which belongs to the technical field of heat insulation materials. Background technique [0002] The energy consumption of buildings in our country is very huge. The important reason is that the heat transfer coefficient of the building maintenance structure is relatively large and the insulation effect is poor. Therefore, it is extremely necessary to develop a new type of wall insulation material. At present, there are two main types of wall insulation materials: insulation mortar and insulation board. Insulation mortar is made of various light materials as aggregate, cement as cement, mixed with some modified additives, and mixed with water in proportion when used. It can be applied by mechanical spraying or manual application. On the outer surface of the building maintenance structure, the commonly used thermal insulation mortars are: rubber powder p...
