Problems solved by technology

However, the current domestic magnesia building board products are good and bad. The raw material is light-burned magnesia, and MgO in light-burned magnesia is generally inactive, and it is easy to form Mg(OH) with a layered and loose accumulation structure during hydration. 2 , resulting in increased porosity of the product, decreased strength, and easier moisture absorption and brine return
Due to the presence of more free Mg in magnesia building boards 2+ Ions, resulting in a lack of waterproof and moisture-proof, which makes the surface of the product appear moisture absorption and brine return in warm and humid weather, and is easy to become brittle, making it difficult for the board to be refurbished or reworked in decoration projects, and existing products still have problems. Disadvantages such as not being able to nail heavy objects, not being able to install wire slots, etc.

Embodiment 1

[0057] Embodiment 1, the structure is shown in Figure 1:

[0058] The product of this embodiment is a kind of lightweight partition wall plate for construction of 5.6cm thick single-layer glass fiber, and its specification is 2.02cm (length) * 1.02cm (width) * 5.6cm (thick).

[0059] Embodiment 1: The board has a central layer, the central layer is composed of a wooden thin board 1 in the middle and two foamed plastic boards 2 up and down, and there is a bond between the wooden thin board and the two foamed plastic boards The material layer 4 is covered with a glass fiber cloth layer 3 around the center layer, and there is a bonding material layer 4 between the center layer and the glass fiber cloth layer and on the surface of the glass fiber cloth. The bonding material layer on the surface of the glass fiber cloth is the surface layer of the partition wall board.

[0060] The raw materials for the preparation of the bonding material layer include: caustic dolomite (CaO MgO),...

Embodiment 2

[0071] According to the following steps, a kind of lightweight partition wall panel for construction as described in the above embodiment is manufactured:

[0072] Firstly, the preparation raw materials of the bonding material layer are stirred into gelatinous paddle material according to the proportion described in the first embodiment, and then the construction is carried out according to the following steps on the production equipment:

[0073] (1) Put a carrier frame on the production equipment platform, and put a smooth flat plate of 2.02m×1.02m on the carrier frame;

[0074] (2) On the smooth flat plate, evenly coat a layer of bonding slurry material according to the size range of the lightweight partition wall plate;

[0075] (3) Lay glass fiber cloth with more edge wrapping size on the bonding slurry material layer;

[0076] (4) Coating a layer of bonding slurry material on the glass fiber cloth;

[0077] (5) The foamed plastic plate (2.5cm or 6cm) that the bottom surf...

Embodiment 3

[0092] Embodiment 3, the structure is shown in Figure 2:

[0093] The difference between this embodiment and Embodiment 1 is that: the center layer is covered with more than two layers of glass fiber cloth 3, and there is a bonding material layer between each glass fiber cloth, and the bonding on the surface of the outer layer of glass fiber cloth The material layer is the surface layer of the partition wall board.

Abstract

The present invention is light partition wall plate for building, and features that the light partition wall plate has one central layer comprising one middle wood sheet and two foamed plastic plates adhered together with adhesive layer, and glass fiber cloth layers adhered with adhesive to the periphery of the central layer. The present invention has high waterproof performance, high surface hardness, high strength, light weight, high heat and sound isolating performance and other features.

Description

technical field [0001] The invention relates to a building component material and a manufacturing method thereof, in particular to a lightweight partition wall plate for building and a manufacturing method thereof. Background technique [0002] In recent years, with my country's increasing emphasis on building fire protection, the use of wood-based combustible organic building boards in buildings, especially public facilities, has been strictly controlled, while the existing asbestos boards, gypsum boards, calcium silicate Inorganic boards such as boards have deficiencies in strength, toughness, water resistance, and sound insulation. Magnesium boards have the light weight, flexibility and reprocessing performance of wood-based organic boards, and have the fire resistance of inorganic boards. attention. However, the current domestic magnesia building board products are not good or bad. The raw material is light-burned magnesia, and MgO in light-burned magnesia is generally in...
