Abstract

The invention discloses a cement foamed inorganic insulating board and a manufacturing technology thereof. The cement foamed inorganic insulating board comprises the following ingredients in parts by weight: 57-63 parts of Portland cement, 19-21 parts of coal ash, early-strength agent which is 3% of the usage amount of Portland cement, hydrated calcium which is 3% of the usage amount of Portland cement, and a proper amount of foaming agent and PP fiber, wherein the usage amount of the PP fiber is 2.7-3.3kg per cubic meter of die volume; the manufacturing technology of the cement foamed inorganic insulating board comprises three stages: pouring, curing and cutting. According to the cement foamed inorganic insulating board and the manufacturing technology thereof, for improving the properties of the existing cement foamed inorganic insulating board, the formula of materials can be optimized, ordinary portland cement is selected to replace sulphate aluminum cement, the production technology can be optimized and improved, so that the quality of the manufactured new product can be greatly improved as compared with that of the existing product, the functional index can be improved by 10% on the original basis, the safety index can be improved by 2.5 times on the original basis, and the quality appearance can be improved by three to four times on the original basis.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a cement foamed inorganic thermal insulation board and a manufacturing process thereof. Background technique [0002] The existing cement foamed inorganic insulation board, also known as: foamed concrete or foamed cement board or foamed concrete board, due to the backward and unreasonable formula and production process, the quality of the product is low. coefficient, its safety indicators, such as mechanical properties, cannot be effectively guaranteed, or vice versa; in addition, because existing products use special cement, such as rapid-hardening sulphoaluminate cement as the main component, resulting in product safety Dimensional stability is poor, and the product is prone to cracking when it is applied. Contents of the invention [0003] The object of the present invention is to provide a cement foamed inorganic thermal insulation board with greatly improved produ...
