Polyurethane spacer rock wool sandwich panel

Polyurethane spacer rock wool sandwich panel is an energy-saving material often used in current projects. Because the polyurethane sandwich panel has a beautiful appearance and good overall effect. It integrates load-bearing, thermal insulation, fire prevention and waterproof, and does not need secondary decoration. It is fast and convenient to install, short in construction period, good in comprehensive benefits, and has good cost-effective advantages. It is a kind of plate with wide applications.

Rigid foam of polyurethane edge rock wool sandwich panel is recognized as a fireproof and thermal insulation panel for building envelope at present. It has low thermal conductivity, good load resistance, high bending strength, no water absorption, no decay, no moth and rat bite, good flame retardancy and wide temperature resistance. Using the physical characteristics and special formula of polyurethane, the polyurethane foaming agent is uniformly sprayed on the color coated steel plate, so that the foaming agent is foamed between the color coated steel plates to form a three-layer disposable polyurethane color steel composite sandwich panel. This new light building material is the combination of color coated steel plate and polyurethane, which is the development direction of light building materials.

Fire protection performance of polyurethane spacer rock wool sandwich panel: it has excellent fire protection performance. Rock wool material can meet higher fire protection performance requirements for building insulation materials and effectively prevent fire spreading, that is, B1 or B2 level flame retardant standard.

The core material of polyurethane barrier rock wool sandwich panel and two layers of steel plate are bonded into a whole to work together. In addition, the upper surface of the roof panel is corrugated and profiled, and its overall stiffness is far better than that of the on-site composite plate with profiled plate and rock wool (glass wool).

The raw materials, production process and formula of polyurethane edge rock wool sandwich panel with excellent fire resistance make it have good fire resistance. Tests show that it has a fire resistance of more than 1000 ℃. The rock wool sandwich panel has passed the test of gloriano S.P, an Italian authoritative testing agency. According to the standards of the international organization for Standardization (ISO), British BS and German DIN, the rock wool sandwich panel meets the requirements of fire protection standard 14 / 09 / 61 letter 91 and d.m.30/11/83.
