Abstract
The utility model relates to a kind of cystosepiment playing the effect of absorbing sound and lowering noise, a kind of composite polyurethane foam plate specifically, this composite polyurethane foam plate is upper and lower symmetrical structure, its intermediate layer is flame retarded polyurethane-foam layer 1, the both sides of flame retarded polyurethane-foam layer are the first glue-lines, the outside of the first glue-line is nonwoven layer, the outside of nonwoven layer is the second glue-line, and the outside of the second glue-line is aluminium foil glass fiber layer of cloth.The utility model is applied to the effect that can play absorbing sound and lowering noise inside vehicle sheet steel, aluminium sheet and has heat insulation function, simple and reasonable, easy to use, can also solve fricative sound between inside gadget simultaneously.
Description
Technical field
The utility model relates to a kind of cystosepiment playing the effect of absorbing sound and lowering noise, specifically a kind of composite polyurethane foam plate.
Background technology
Since reform and opening-up, particularly in recent years the auto industry of China and track traffic growth momentum powerful.Along with the raising of individual family income, automobile and track traffic have become the first-selection of people's trip, people except higher requirement, more pay attention to the comfortableness in its vehicle travel process except proposing for the brand of automobile and track train, safety and quality in the process of trip.
Traditional automobile and the inner side of track train, do not add corresponding noise reduction and insulation material, and shortcoming produces resonance in vehicle travel process, and noise is comparatively large, brings very large trouble and puzzlement, have impact on the comfortableness in trip process to the trip of people.
The impact of vehicle noise on health is many-sided, and function of noise, in the central nervous system of people, makes the corticocerebral excitement of people and suppresses dysequilibrium, causes conditioned reflex abnormal, cerebrovascular tension force is damaged.These physiological changes, can restore to the original state in early days, but the time one is of a specified duration, will cause the change on pathology, make that people produces headache, brain is swollen, tinnitus, have a sleepless night, be losing one's memory and the symptom such as general fatigue is unable.If pregnant woman takes the larger vehicle of noise for a long time, noise can by acting on central nervous system effects development of fetus.
Summary of the invention
The purpose of this utility model to provide a kind of composite polyurethane foam plate, this cystosepiment is applied to the effect that can play absorbing sound and lowering noise inside vehicle sheet steel, aluminium sheet and has heat insulation function, simple and reasonable, easy to use, fricative sound between inside gadget can also be solved simultaneously.
The purpose of this utility model realizes like this, this composite polyurethane foam plate is upper and lower symmetrical structure, its intermediate layer is flame retarded polyurethane-foam layer, the both sides of flame retarded polyurethane-foam layer are the first glue-lines, the outside of the first glue-line is nonwoven layer, the outside of nonwoven layer is the second glue-line, and the outside of the second glue-line is aluminium foil glass fiber layer of cloth.
The utility model has the following advantages and good effect:
1, the utility model is compared with existing polyurethane foam, and composite polyurethane foam has compound felt and non-woven fabrics aluminium foil, plays better noise reduction and heat insulation function, can solve fricative sound between inside gadget.
2, simple and reasonable, easy to use, the effect with absorbing sound and lowering noise of the utility model and there is heat insulation function.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure sectional view.
Detailed description of the invention
Shown in accompanying drawing 1: this composite polyurethane foam plate is upper and lower symmetrical structure, its intermediate layer is flame retarded polyurethane-foam layer 1, the both sides of flame retarded polyurethane-foam layer 1 are the first glue-lines 2, the outside that the outside of the first glue-line 2 is nonwoven layer (felt) 3, the outside of nonwoven layer 3 is second glue-line 4, second glue-lines 4 is aluminium foil layer (aluminium foil glass fiber fabric) 5.
The utility model is applied to the effect that can play absorbing sound and lowering noise inside vehicle sheet steel, aluminium sheet and has heat insulation function.
