Problems solved by technology

Compared with organic thermal insulation materials, traditional inorganic thermal insulation materials have the advantages of good compressive strength and flexural strength, excellent fire resistance and high durability. With the increase of the market share of inorganic thermal insulation materials, the disadvantages of traditional inorganic thermal insulation materials are also Highlighted, such as poor thermal insulation, complicated construction steps, and large limitations in application range, etc.
Today, when building energy conservation is becoming more and more important, these traditional building materials do not meet the requirements of energy conservation

Embodiment 1-6

[0055] The components and proportions of the slurry compositions in Examples 1-6 of the present invention are shown in Table 2 below.

[0056] According to the composition ratio of Examples 1-6, the thermal insulation board is prepared according to the following steps:

[0057] First weigh the reinforcing fiber and soak it in water at 60°C to 80°C with a small amount of sodium dodecylbenzenesulfonate, stir continuously until it becomes a slurry; take lightweight aggregate and soak it in water at room temperature for 1-2 hours;

[0058] According to the corresponding examples in Table 2, weigh the aforementioned pretreated aqueous inorganic binder solution (numbered as WNOA-1 ~ WNOA-9), the reinforcing fiber solution, and add them to the mixer together with the magnesium-containing minerals in, and add an appropriate amount of water to mix and stir to obtain a slurry.

[0059]Add fillers weighed according to the corresponding examples in Table 2 and pretreated lightweight aggr...

Embodiment 7-54

[0071] The present invention can also add one or more of inorganic powdery binders, foaming agents, active agents, and stabilizers to the slurry composition on the basis of Examples 1-6, and its specific slurry combination See Example 7-54 in Table 3 for details.

[0072] According to embodiment 7-54, heat insulation board is prepared according to the following steps:

[0073] First weigh the reinforcing fiber and soak it in water at 60°C-80°C plus a small amount of sodium dodecylbenzenesulfonate, stir continuously until it becomes a slurry; take lightweight aggregate and soak it in water at room temperature for 1-2 hours; The components in the mineral and inorganic powder binder are stirred and mixed evenly; the foaming agent, active agent, and stabilizer are dissolved in water respectively, and set aside;

[0074] Take the aforementioned pretreated aqueous inorganic binder solution (numbering is WNOA-1~WNOA-9), the reinforcing fiber solution respectively by the correspondin...

Description

【Technical field】 [0001] The invention relates to the field of building materials, in particular to a thermal insulation slurry composition and an application thereof. 【Background technique】 [0002] In recent years, with the development of the economy, my country has gradually increased its emphasis on the field of building energy conservation. In order to achieve building energy saving and consumption reduction, the strategy currently adopted in my country is mainly to treat the building maintenance structure to reduce the heat transfer coefficient of the wall and roof. The specific way is to increase the laying of thermal insulation materials in the building maintenance structure. At present, most of the building thermal insulation materials produced and applied in my country are organic materials. Typical polystyrene board insulation systems and polyurethane insulation systems made of polystyrene pellets or polyurethane pellets have low thermal conductivity. , used in bu...
