Abstract

The invention discloses a manufacturing process of a flexible thermal insulation board. The raw material composition is stirred into a gel, the gelled raw material composition is input into a mold, the mold is sent into a pressing platform, and the pressing The mold is heated in the platform, a heating plate is arranged in the pressing platform, and the raw material composition is directly squeezed by using the heating plate, so that the temperature inside the raw material composition reaches 65-130 ° C, and the raw material composition is heated. When the pressure inside the composition reaches 0.1MPa-0.3MPa, it can be maintained for more than 8 minutes, then demolded and cured. The compressive strength of the flexible thermal insulation board produced by the production process of the invention is increased to more than 0.25MPa, the tensile strength is increased to more than 0.18MPa, the bending deformation value is more than 3mm, the thermal conductivity is less than 0.06W / (m∙K), and the fire rating is Upgrade to A2 class (non-combustible).

Description

technical field [0001] The invention relates to the field of building materials, in particular to a manufacturing process of a flexible thermal insulation board. Background technique [0002] With the improvement of energy-saving standards year by year, the external wall insulation technology has been developed by leaps and bounds, and has become an important building energy-saving technology in my country. However, in recent years, accidents such as falling off of external wall insulation materials and fires have occurred frequently, resulting in heavy casualties and property losses. With the comprehensive promotion of building energy conservation, especially the fire prevention of building energy-saving materials is becoming more and more serious. At present, the thermal insulation materials used for external wall thermal insulation are mainly divided into two categories: inorganic thermal insulation materials and organic thermal insulation materials, but these materials ...
