Embodiment

[0024] A light-duty thermal insulation calcium-silicon composite board, which is composed of two structures, the surface layer and the inner layer, and the weight parts of the raw materials for the two structures are respectively:

[0025] surface layer:

[0026] 40 parts of fly ash, 15 parts of quartz sand, 10 parts of sanding powder, 15 parts of calcium carbide mud, 30 parts of magnesium oxide, 20 parts of magnesium chloride, 40 parts of cement, 20 parts of modified perlite powder, 5 parts of glass fiber,

[0027] The modified perlite is prepared by the following method: add perlite powder into a high-speed kneader, preheat and dry to 120°C, add 2.5% ammonia water and 0.3% silane coupling agent WD-70, stir for 30 minutes, and dry It can be dry ground into 250 mesh powder, and the rotation speed of the high-speed kneader is 800r / min when stirring,

[0028] inner layer:

[0029] 50 parts of coal gangue powder, 30 parts of slag, 25 parts of powdered quartz, 20 parts of ri...

Abstract

The invention discloses a light heat preservation silicon and calcium compound plate, which consists of an outer layer structure and an inner layer structure. The plate is manufactured by waste coal ash generated by local rich coal mine resources and crop stalks, so that waste is recovered, and the plate is beneficial to environment friendliness. The plate takes inorganic substances such as powder quartz, quartz sand, sanding powder and the like as main raw materials, has the advantages of high strength, aging resistance, ultraviolet resistance, water resistance, fire prevention, heat preservation and the like, is widely applied, does not have toxic or side effect and is pollution-free.

Description

technical field [0001] The invention relates to a light-duty thermal insulation composite silicon-calcium composite board, which belongs to the technical field of new wall materials. Background technique [0002] Calcium silicate board, also known as gypsum composite board, is a multi-component material, generally composed of natural gypsum powder, white cement, glue, and glass fiber. It has the properties of fire prevention, moisture resistance, sound insulation and heat insulation. It can attract water molecules in the air when the indoor air is humid, and release water molecules when the air is dry. It can properly adjust the indoor dryness and humidity and increase comfort. Natural gypsum products are also special-grade fireproof materials, which can produce endothermic reactions in flames, and at the same time, release water molecules to prevent the spread of fire, and will not decompose to produce any toxic, corrosive, and suffocating gases, nor will they produce Any ...
