Embodiment 1

[0007] A composite material and a preparation method thereof of the present invention are composed of the following components in parts by weight: 100 parts of fly ash, 50 parts of rubber particles, 45 parts of sand, 10 parts of kaolin, 1 part of magnesium oxide, and the rest of water, etc. design is formed.

[0008] Fly ash, English name: fly ash, the fine ash that is carried out of the furnace by the flue gas formed after the coal is burned in the boiler, and the dust collected by the vacuum cleaner from the flue of the coal-fired thermal power plant. Commonly used as concrete admixture, fine dust generated during coal combustion. Composed of organic and inorganic substances, it can be used as a filling material after comprehensive utilization of its combustible components. Gypsum powder is a white powder, non-combustible, non-toxic, with a density of 900kg / m3. Gypsum is usually white, colorless, and colorless transparent crystals are called permeable gypsum. Sometimes it b...

Embodiment 2

[0012] A composite material and a preparation method thereof of the present invention are composed of the following components in parts by weight: 100 parts of fly ash, 75 parts of rubber particles, 60 parts of sand, 30 parts of kaolin, 5 parts of magnesium oxide, and the balance of water, etc. design is formed.

[0013] Kaolin, pure kaolin has high whiteness, soft quality, easy to disperse and suspend in water, good plasticity and high cohesiveness, excellent electrical insulation performance; has good acid solubility, low cation exchange capacity, relatively Good fire resistance and other physical and chemical properties. The composition of kaolin is SiO257.03%, Al2O330.32%, Fe2O31.42%, CaO0.55%, MgO0.49%, K2O2.53%, Na2O0.31%, TiO21.44%. In the embodiment of the present invention, 30 parts of kaolin, 100 parts of fly ash, 75 parts of rubber particles, 60 parts of sand, 5 parts of magnesium oxide, and the balance of water are used in combination to design a material with mul...

Embodiment 3

[0015] A composite material and a preparation method thereof of the present invention are composed of the following components in parts by weight: 100 parts of fly ash, 60 parts of rubber particles, 50 parts of sand, 15 parts of kaolin, 2 parts of magnesium oxide and the like.

[0016] Magnesium oxide, properties: white amorphous powder. Odorless, tasteless and non-toxic. Due to different preparation methods, there are light and heavy points. It has strong refraction in the visible and near ultraviolet range. When exposed to the air, it is easy to absorb water and carbon dioxide and gradually become basic magnesium carbonate. The light weight is faster than the heavy weight. It combines with water to form magnesium hydroxide, which is slightly alkaline. The pH of the saturated aqueous solution is 10.3. But it is very soluble in dilute acid, very slightly soluble in pure water, and its solubility is increased by the presence of carbon dioxide. It is a mild catalyst. Insolubl...

Abstract

The invention discloses a composite material and a preparing method thereof. The composite material is prepared from, by weight, 100 parts of coal ash, 50-75 parts of rubber particles, 45-60 parts of sand, 10-30 parts of kaolin, 1-5 parts of magnesium oxide and the balance water. The requirement for water absorption rate, inflame retarding rate and strength can be met, and heat insulation can also be achieved; besides, the preparing method is simple and environment-friendly, and has high economic and social value.

Description

technical field [0001] The invention relates to the field of construction, in particular to a composite material and a preparation method thereof. Background technique [0002] At present, most of the materials used in the construction field are concrete and cement, which are easy to pollute the environment, and their water absorption rate, flame retardancy rate, and strength are not ideal, which affects the overall building quality.
