Abstract
The utility model provides a polyurethane wallboard of a mobile house, belonging to the field of novel plate. The polyurethane wallboard of a mobile house comprises a first steel plate, a first fireproof layer, a polyurethane plate, a second fireproof layer and a second steel plate which are pressed-fitted in order; the polyurethane plate is provided with a plurality of pores; and the pores are vertical to the surface of the polyurethane plate. The polyurethane wallboard of a mobile house provided by the utility model has the advantages of being capable of preventing fire, preserving heat, and efficiently improving the sound-absorbing performance of the wallboard of a mobile house, as well as simple in manufacturing process.
Description
Technical field
The utility model belongs to the board field, especially relates to a kind of polyurethane prefabricated house wallboard.
Background technology
Mainly there is following shortcoming in prefabricated house in the market: the house dismounting is inconvenient, is not easy to transportation automatically greatly, the wallboard that especially uses bamboo wood or other materials to process, and fire prevention, heat-proof quality are poor, and the wallboard sound-absorbing effect is poor, and it is uncomfortable to live, and lack application life.
Summary of the invention
The purpose of the utility model provides a kind ofly not only can be prevented fires, be incubated, and can effectively improve the sound absorption qualities of prefabricated house wallboard, the simple polyurethane prefabricated house of manufacturing process wallboard.
The technical scheme of the utility model is: a kind of polyurethane prefabricated house wallboard; Comprise first steel plate, first fireprotection layer, polyurethane sheet, second fireprotection layer and second steel plate that press together in order; Said polyurethane sheet has several apertures, and said aperture is perpendicular to the surface of this polyurethane sheet.
Said aperture is a honeycomb type.
The utility model not only can prevent fires, be incubated, and can effectively improve the sound absorption qualities of prefabricated house wallboard, and manufacturing process is simple.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the sectional drawing of the polyurethane sheet of the utility model.
Among the figure:
1, polyurethane sheet 11, aperture 21, first fireprotection layer
22, second fireprotection layer 31, first steel plate 32, second steel plate
The specific embodiment
Like Fig. 1, shown in Figure 2; A kind of polyurethane prefabricated house of the utility model wallboard; Comprise first steel plate 31 that presses together in order, first fireprotection layer 21, polyurethane sheet 1, second fireprotection layer 22 and second steel plate 32; Steel plate can make mobile house firmer, and fireprotection layer can make wallboard have flameproof effect; Polyurethane sheet 1 has the aperture 11 of several honeycomb types; Aperture 11 is perpendicular to the surface of this polyurethane sheet 1; Through these apertures 11, make the cellular unit of original sealing become foraminate cellular unit, when sound wave propagates into polyurethane sheet 1; Sound wave gets into polyurethane sheet 1 inside from aperture 11, can repeatedly reflect within it.But,, effectively reduce the acoustic wave energy in the reflected back mobile house so repeatedly reflection can consume most acoustic wave energy because of the equal consumed energy of each acoustic reflection.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
