Background technology
Along with the economic and development of society, the saving energy and protection environment have become the common recognition of the mankind, reduce the consumption of the energy
Become the target that the mankind make joint efforts.In order to enable more effectively to save the energy, energy saving building becomes an important problem, changes
The heat-insulating property of kind building, the energy resource consumption that air-conditioning is caused, significant effect can be played, therefore building is to high property
The demand of the heat-insulating heat-preserving material of energy consequently also increases.
XPS extruded sheet or title extrusion moulding type polystyrene heat insulating board, be former auxiliary plus other with polystyrene resin for raw material
Material and poly-inclusion, be injected simultaneously into catalyst by adding hot mixing, then extrusion molding extrusion molding and the rigid foam plate that manufactures.
Graphite polystyrene board (SEPS) and extruded polystyrene board (XPS) are all reasonable adiabators, heat-insulating property extruded polystyrene board
(XPS) graphite polystyrene board (SEPS) slightly it is better than, owing to the use density of XPS is far longer than the use density of EPS, its material
Cost is the highest.Graphite polystyrene board (SEPS) has good breathability, can completely cut off rainwater, and moisture in body of wall can be made again to pass through,
Effectively solve the breathability of building.And the excellent properties of the high anti-vapour permeability of extruded polystyrene board (XPS) is for external wall outer insulation,
This point just, the moisture that it hinders in body of wall passes through, and makes moisture be gathered in a large number between body of wall and XPS heat-insulation layer, easily makes
Become heat-insulation layer deformation and adhesive layer to come off, directly affect the service life of external thermal insulation system, and external thermal insulation system
Safety.
