Abstract
The utility model relates to a fire -retardant fall the make an uproar novel polyurethane material of dress in the aluminium alloy die cavity, a fire -retardant foamed material that makes an uproar that falls of vacuum shrink polyurethane specifically says so. This fire -retardant foamed material that makes an uproar that falls of vacuum shrink polyurethane comprises at the fire -retardant polyethylene film parcel layer of fire -retardant type polyurethane trompil foamed material layer outside two parts with setting up the fire -retardant type polyurethane trompil foamed material layer in inside. Can provide heterotypic size according to the filling position during use, install after the sealed vacuum production, the installation final vacuum resumes the product structure. This NULL is in the sealed sound of inhaling of building interior trim, in the vehicle automobile body abnormal shape mechanism, plays and inhales the sound and fall and make an uproar and the heat preservation effect, and simple structure is reasonable, simple to operate.
Description
Technical field
The utility model relates to a kind of fire-retardant noise reduction new polyurethane material be contained in aluminium section bar die cavity, specifically says it is a kind of vacuum constriction polyurethane flame-proof noise reduction foamed material.
Background technology
Noise reduction technology has minimizing interference for building, vehicle, the material absorption of noise of business machine employing sound absorption, reduction noise intensity, provides comfort level important in inhibiting.In traditional carbody, do not fill or filling glass silk flosssilk wadding, assimilation effect is low, and the resonance that vehicle produces under steam very easily makes driver produce fatigue, the comfort level in impact trip and safety factor.
Building and vehicle noise can excite nerve system, make it to produce to suppress, and the people worked under noisy environment for a long time, also can cause neurasthenia disease group, and the harm of noise is many-sided.Noise not only causes very big interference to people's normal life and work, affects people's talk, thinking, affects the sleep of people, make people produce agitation, slow in reacting, operating efficiency reduces, and takes sb's mind off sth, cause operating irregularity, more serious situation is that noise can make the hearing of people and health suffer damage.
Summary of the invention
The purpose of this utility model will provide a kind of vacuum constriction polyurethane flame-proof noise reduction foamed material, and this materials application, in building interior trim sealing sound-absorbing, in the special-shaped mechanism of carbody, plays absorbing sound and lowering noise and insulation effect, simple and reasonable, easy for installation.
The utility model object is achieved in that this vacuum constriction polyurethane flame-proof noise reduction foamed material is made up of internal ignition resistant type polyurethane open-cell foam layer and the flame-proof polyethylene film integument two parts be arranged on outside flame-retardant polyurethane open-cell foam layer.According to filling position, special-shaped size can be provided during use, install after sealing is evacuated, final vacuum is installed and recover product structure.
The utility model has the following advantages and good effect:
1, the utility model flame retardant polyurethane core has evenly tiny many holes, and mutual UNICOM between hole and hole is also directly connected with ambient atmosphere, has certain aeration.The air between channels and collaterals can be caused when sound wave is propagated in space to move back and forth, make acoustic energy be converted into heat energy and consume, thus play a part to absorb acoustic energy.
2, the utility model is compared with existing polyurethane foam, adds fire resistance, the protection of external packing flame-proof polyethylene film, and advanced vacuum constriction technology, improves installation effectiveness.
3, the utility model material core is resistance combustion polyurethane foam, external packing flame-proof polyethylene film, vacuumize rear one to install, be applied in sandwich boards for construction decorative panel, absorbing sound and lowering noise and heat insulation function is played in vehicle sheet steel, aluminium sheet, aluminium cavity, have simple and reasonable, the features such as density is low, easy for installation.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure sectional view.
Fig. 2 a, 2b, 2c are the sectional views that the utility model three kinds implements planform.
Fig. 3 a, 3b, 3c are the using state sectional views that the utility model three kinds implements planform.
Detailed description of the invention
Shown in accompanying drawing 1: this vacuum constriction polyurethane flame-proof noise reduction foamed material is made up of internal ignition resistant type polyurethane open-cell foam layer 1 and outside flame-proof polyethylene film integument 2 two parts.
Shown in accompanying drawing 2a, 2b, 2c: according to filling position, special-shaped size can be provided during use.
Shown in accompanying drawing 3a, 3b, 3c: the utility model is applied to decorative panel for building sealing sound-absorbing, absorbing sound and lowering noise and insulation effect in automobile and rail traffic vehicles car body.Install after sealing is evacuated, final vacuum is installed and recovers product structure.
