Description
Technical field
The invention belongs to the technical fields of composite material for decoration, provide a kind of polystyrene bubble for interior/exterior decoration
Foam plate and preparation method.
Background technique
Polystyrene foam plate is mainly used for construction wall, roof heat insulation, composite plate heat preservation, freezer, air-conditioning, vehicle, ship
The insulation of oceangoing ship, floor heating, the fields such as decoration engraving.Since polystyrene foam plate has light, sound insulation, heat-insulated etc. excellent
Point is commonly used for interior/exterior decoration field.
However, the mechanical strength and toughness of polystyrene foam plate are poor, limit its application.Using fiber to polyphenyl second
Alkene cystosepiment is modified, and can significantly improve the mechanical property of material, expanded application range.But the addition of fibrous material, it is special
It is not the addition of inorganic fibers, due to unavoidably there is phase interface between inorfil and polystyrene matrix, in fibre
Interface hole is formed between dimension and polystyrene, hydrone can enter foam interior by interface hole, and along hydrophilic
The good inorfil of property is diffused.Therefore, the water absorption rate of inorfil modified polystyrene cystosepiment is higher, moisture resistance compared with
Difference.
In addition, people are higher and higher to the cosmetic requirements of dalle, and the surface tactile sensation of polystyrene foam plate is bright
Aobvious too late wood materials and ceramic material, are restricted it in the application of high requirement.
