Problems solved by technology

[0011] The existing non-burning brick pallet, the steel plate has the best effect, but the price is expensive; the bamboo / wood plywood has poor water resistance, and it will crack in layers after long-term use; the plastic formwork has poor temperature resistance, and the rigidity becomes poor and easy to deform when the temperature is high

Embodiment 1

[0102] Embodiment 1 (see attached Figure 1~3 )

[0103] A multi-layer composite board, which uses magnesium cement gel as the main material, and is made by adding reinforcing materials and fillers; it is characterized in that: the multi-layer composite board specifically includes a surface layer 1 constituting the outer surface and a surface layer located on the outer surface Core layer 2 within;

[0104] The surface layer 1 is arranged on both sides of the core layer 2 respectively; each layer of the surface layer 1 or / and the core layer 2 contains fillers and reinforcing materials with uniform content; wherein, the reinforcing materials are arranged on adjacent between layers; fillers are physically and / or chemically arranged in layered materials;

[0105] The core layer 2 is arranged in the surface layer 1 on both sides, and the core layer 2 has 1 to 5 layers in total; reinforcing materials are arranged between different adjacent core layers 2 and between the surface lay...

Embodiment 2

[0167] Embodiment 2 (see attached figure 1 , 2 、4)

[0168] The content of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[0169] 1) The surface layer 1 of the multi-layer composite sheet is arranged on both sides of the core layer 2 or on a single side of the core layer 2; each layer of the surface layer 1 or / and core layer 2 contains a uniform Filler, the content of the filler in each of the two adjacent layers changes in a gradient;

[0170] The core layer 2 is arranged in the surface layer 1 on both sides, and the core layer 2 has three layers in total; reinforcing materials are arranged between different adjacent core layers 2 and between the surface layer 1 and the core layer 2; the reinforcing materials are arranged in The boundary between adjacent layers can be sequentially prepared by layering; the filler is physically or / and chemically arranged in the layered material;

[0171] 2) Among the raw materials of the main materi...

Embodiment 3

[0193] The content of this embodiment is basically the same as that of Embodiment 1, the difference is that:

[0194] 1) The upper and lower surfaces of the multilayer composite sheet (the outermost side of the surface layer 1) only have non-woven fabrics on one side or no non-woven fabrics on both sides;

[0195] 2) In the multi-layer composite board, only a few of the boundaries between different adjacent core layers 2 and between the surface layer 1 and the core layer 2 are provided with reinforcing materials: medium-alkali or alkali-free glass fiber cloth or polyester chemical fiber cloth; 2 to 3 layers of reinforcing materials can be overlapped at some boundaries: medium-alkali or alkali-free glass fiber cloth or polyester chemical fiber cloth.

Abstract

The invention discloses a multilayer composite plate for building templates and brick pallets, which is prepared from magnesium cement gel added with a reinforcing material and a filler, and comprises surface layers (1) and sandwich layers (2); the surface layers (1) or / and the sandwich layers (2) comprise the filler or / and the reinforcing material with even content or gradient change; the number of the sandwich layers (2) is totally between 1 and 5; and the reinforcing material is arranged between adjacent sandwich layers (2). The invention also comprises a preparation process for the multilayer composite plate, which comprises that: production equipment with the capacity of stirring and preparing materials at multiple positions and rolling at multiple positions orderly rolls the surface layers (1) or / and the sandwich layers (2) on a subplate (3); and the reinforcing material is used as a reinforced structure between adjacent surface layers (1) or / and sandwich layers (2). The products corresponding to the invention have the characteristics of strong applicability, good technical effect and suitability for mechanical continuous production, and have predictable great economic and social values.

Description

technical field [0001] The invention relates to building materials and a preparation process thereof, and in particular provides a multi-layer composite board which can be used for building templates and brick machine pallets and a preparation process thereof. Background technique [0002] In the prior art, magnesite plates are widely used in engineering and have a great impact on people's production and life. Among them, building formwork is a kind of magnesite board with great application prospects. [0003] The existing building formwork is mainly based on film-coated wood plywood, bamboo plywood and steel plate, and plastic formwork is also gradually applied. Formwork engineering is an important basic engineering in construction, and building formwork is the core part of formwork engineering, which is widely used in construction. With the continuous improvement of construction quality and technical level, people's performance and quality requirements for building formw...
