Abstract
The invention discloses a feather sound absorption composite board and a manufacturing method thereof. The feather sound absorption composite board comprises multilayer net bodies formed by feather fibers, jute fibers and polypropylene fibers. The multilayer net bodies are combined into a whole through the hot press molding technology, and the composite board is formed. The method for producing the feather sound absorption composite board comprises the steps of first fully mixing the feather fibers, the jute fibers and the polypropylene fibers; forming nets through carding and drying the nets; finally manufacturing the multilayer net bodies into the composite board through the hot press molding technology. The feather sound absorption composite board has good sound absorption performance and is favorable for recycle of the waste feather fibers. In addition, the source of fiber materials is wide.
Description
Technical field
The present invention relates to a kind of feather sound-absorption composite board and preparation method thereof, belong to building and field of textiles.
Background technology
The chamber internal surface of building comprises ceiling, metope and ground, if only decorated with hard closely knit stone material, plank and plastering, because these materials can produce strong reflection to sound wave, on the one hand because reflected sound makes indoor sound strengthen; Make room reverberation time lengthening on the other hand.Carry out attending class, having a meeting or theatrical performances in this room, although audience feels that sound is very loud, only hear that very unsharp a slice " rumbles grand " sound.Therefore sound absorption finishing need be made in general indoor, and particularly arenas, concert hall, dancing hall, cinema, studio and recording room etc., the acoustical quality of this kind of building is vital.Utilizing sound absorption material to absorb noise, is the major measure taked at building field reduction room noise.
Porous material is as common sound absorption material, and description is maximum, applies also extensive.The inorganic fibrous porous absorption material such as glass wool, mineral wool, rock wool, aluminium silicate wool is porous absorption material the most common. this kind of material appearance has identical fibre morphology and structure, has good sound absorption, thermal insulation, heat-insulating property.But this kind of material also has shortcoming, need when producing to consume a large amount of energy and mineral material; Fiber frangibility, easily to fly upward; Product easily produces solid waste after using, not easily degrades, and can pollute, and can not reuse human and environment.In today that environmental consciousness is more and more stronger, this kind of material has obviously been not suitable for large area and has used.
Using the waste feathers of domestic fowl farming generation as the main reinforcement fibres in feather sound-absorption composite board, " can turn waste into wealth ", reduce the waste of resource.And feather fiber, tossa and polypropylene fibre are cheap, can save production cost.
Summary of the invention
The object of this invention is to provide the preparation method of a kind of feather sound-absorption composite board and this material.This kind of feather sound-absorption composite board has excellent sound absorbing capabilities, fire resistance and heat-insulating property, fibrous material wide material sources recoverable, is conducive to environmental protection.
For achieving the above object, the present invention takes following design scheme: a kind of feather sound-absorption composite board: it is characterized in that: it comprises the multilayer dictyosome formed by feather fiber, tossa and polypropylene fibre, described multilayer dictyosome is by described polypropylene fibre melting, and thermocompression forming forms composite plate.
The component of described dictyosome material is: feather fiber 0-50 part, tossa 50-0 part, polypropylene fibre 50 parts.
The invention provides the preparation method of this feather sound-absorption composite board, comprise the following steps:
1) by feather fiber 0-50 part, tossa 50-0 part, polypropylene fibre 50 parts fully mixing rear feeding carding machine is carded to dictyosome 4 times;
2) by dictyosome lay layer by layer, multilayer dictyosome is formed;
3) multilayer dictyosome is placed on 24h on 115 DEG C of heating panels to ensure to remove the moisture existed;
4) the multilayer dictyosome mould after drying is cut into block and dictyosome is stacking, thus the weight/unit area (Kg/m needed for obtaining
2);
5) pressing plate is pressurized to required specified pressure and the temperature preset, pressurization certain hour;
6) pressing plate is cooled to release pressure after lower temperature, takes out composite plate.
Described step 1) in feather fiber be the waste products of poultry enterprise.
Described step 4) in pressing plate moulding pressure be 0.5-1.5MPa, platen temperature is 165-185 DEG C (melt temperature of polypropylene cores is 160 DEG C), and compression time is 3-9min.
