Novel lightweight marble composite material

Abstract

The invention relates to a novel lightweight marble composite material. The novel lightweight marble composite material has the characteristics of light weight, heat insulation, flame retardance, impact resistance, corrosion resistance and the like and can be widely applied to the fields of building outer walls, partition walls, wall hanging and the like. A preparation process comprises the following steps: firstly, selecting a glass fiber as a raw material and preparing an integral hollow fabric by a special three-dimensional weaving process; secondly, preparing a resin system according to the ratio of phenolic resin to a curing agent (hexamethylene tetramine) to an accelerator (661) being 100:10:1; thirdly, compounding the resin system with the integral hollow fabric according to the ratio of 1.1:1 to form an integral hollow composite material; fourthly, uniformly splitting a marble board into marble sheets by using a special tool and then polishing the marble sheets by using a No.150 diamond module and cleaning the marble sheets by using crystallizing powder; fifthly, bonding the integral hollow composite material with the marble sheets by using the phenolic resin system; sixth, placing the bonded composite material in a baking oven (60DEG C) for 4 hours and curing to obtain the lightweight marble composite material.

Description

Technical field: [0001] The invention relates to a novel lightweight marble composite material, which belongs to the technical field of architectural decoration materials. Background technique: [0002] Marble has the advantages of no deformation, high hardness, long service life and non-magnetization, and has been widely used in the construction industry. However, with the progress of society, human beings' requirements for nature and living environment have been further improved, and there are also higher requirements for the cost performance of marble. It is specifically reflected in the following aspects: (1) As a building material, marble is gradually favored by people because of its natural material and ever-changing colors and patterns, thus increasing the demand for marble, and the raw materials in some areas have been in short supply. The shortage of marble raw materials will lead to the rise of marble prices; (2) The density of marble is high, and large pieces of ...

Problems solved by technology

[0005] However, traditional sandwich structure composite materials such as aluminum-plastic panels and aluminum honeycomb panels are made by laminating two reinforced panels and a core material with a lower density by bonding, and the interlayer performance is poor.

Under the action of external load, the face plate and core material will be delaminated, resulting in a comprehensive decline in mechanical properties, which can easily lead to structural damage

In addition, in hot and humid environment, water immersion will occur, causing panel blistering and other phenomena, making inspection and maintenance more frequent, thus affecting product quality and cost

In addition, when using aluminum-plastic panels and aluminum honeycomb panels as the base plate, the marble composite materials must be pasted with glue during the construction process. The quality of the glue and the pasting technology will affect the overall effect of the marble composite materials and increase the difficulty of construction.
