Problems solved by technology

At present, there are two methods of external thermal insulation systems widely used in external walls: thin plastering of externally attached thermal insulation boards and vacuum thermal insulation boards. Difficult to guarantee and other shortcomings, the latter has the disadvantages that after long-term use of the insulation board, the vacuum degree is reduced, and the heat insulation effect needs to be improved, and the existing insulation board is easy to expand after the barrier bag is damaged, so that the insulation board is still lost. The performance of heat insulation, and the insulation board used at this stage is not only thicker, but also has a large thermal conductivity, and the use effect is not very ideal

Embodiment 1

[0023] Embodiment 1, the processing method of a kind of STP exterior wall vacuum insulation board provided by the present invention, comprises the following steps:

[0024] Step 1, prepare the core board, add the following inorganic fibers 90-95% by weight, tapioca starch 2-5%, kaolin 1-3%, moistureproof agent 0.5-1% and glass microspheres 2-4% Stir evenly in 40%-55% sulfuric acid solution to obtain a slurry; add water to dilute the obtained slurry to a mass concentration of 2%-3%; use a paper machine for wet forming to obtain wet paper, and then use a vacuum degree of 0.5~ Under the condition of 0.8MPa, the wet paper is sucked and dehydrated to make the moisture content of the wet paper<18%; the wet paper is dried at 300~400°C.

[0025] Step 2. Put the obtained core board into an oven for baking treatment. The oven drying temperature is 260°C-300°C, the drying time is 8min-15min, and the ambient temperature and humidity are 20°C, 25°C or 28°C. The humidity is 10%RH, 15%RH, 2...

Embodiment 2

[0032] Embodiment 2, Embodiment 1 The composition of each raw material of the core board is 92% of inorganic fiber, 3% of tapioca starch, 2% of kaolin, 0.8% of moisture-proof agent and 2.2% of glass microspheres.

Embodiment 3

[0033] Embodiment 3. Embodiment 1 The composition of each raw material of the core board is 93% of inorganic fiber, 2.5% of tapioca starch, 1.5% of kaolin, 1% of moisture-proof agent and 2% of glass microspheres.

Abstract

The invention discloses a processing method of an STP external wall vacuum insulation board, which comprises the following steps: step 1, preparing a core board, step 2, putting the obtained core board into an oven for baking treatment; step 3, preparing the core board Place a suction bag with a getter on the surface; step 4, bagging; step 5, vacuum packaging; step 6, sealing; step 7, standing; . Advantages of the present invention: the material of the present invention is natural mineral raw materials, does not contain any harmful substances, has stable quality, large thermal resistance, high vacuum degree, low thermal conductivity, and long service life, so that the insulation board can maintain the performance of heat insulation for a long time.

Description

technical field [0001] The invention relates to the technical field of thermal insulation, in particular to a processing method of an STP external wall vacuum thermal insulation board. Background technique [0002] my country is a big energy-consuming country. With the continuous and rapid development of my country's economy, building energy consumption accounts for about 30% of the total energy consumption of our society, and the form of building energy conservation is urgent. The climate in various regions of our country is quite different, and the requirements for building energy-saving design in different regions are different. GB50176-1993 "Code for Thermal Engineering Design of Civil Buildings" clearly states that the design requirements for regions with hot summer and warm winter are "must fully meet the heat protection requirements in summer, Generally, winter heat preservation is not considered.” The industry has reached a consensus that “the north is heat preservat...
