Abstract
The utility model provides a phenol -formaldehyde resin gives sound insulation and fills up, including the glass fiber layer, the upper and lower two sides on glass fiber layer is provided with non -woven fabrics layer and lower non -woven fabrics layer respectively, the PE bisque has been spilt on the single face on last non -woven fabrics layer and lower non -woven fabrics layer. This phenol -formaldehyde resin gives sound insulation and fills up is 220 DEG C, pressure in the temperature and moulds the shaping for heat under 13MP's the high temperature high pressure condition. The utility model discloses a noise that PE bisque messenger got into produces the diffuse reflection and makes the noise successive layer weaken, is showing the absorbing effect who promotes the product, and the PE powder does not have the leakproofness and can not make the product in mould ability gassing and lamination simultaneously, has eliminated quality risk.
Description
Technical field
The utility model belongs to material for car interior trim parts technical field, is specifically related to a kind of phenolic resins sound insulating pad.
Background technology
Vehicle noise insulation pad is arranged on automobile front wall and drives the position such as cabin, main carpet, plays heat insulation and deadening, for wrapping automobile cabin, is reaching under the shockproof effect of sound-absorbing, is also the crucial interior trim of the comfort level improved in car.
And existing phenolic resins sound insulating pad is formed at high temperature under high pressure by non-woven fabrics and glass fibre, wherein non-woven fabrics adopts and is added eedle-punched non-wovens formed by PE (polyethylene) film.There is following defect in the phenolic resins sound insulating pad of this structure:
(1) due to the good airproof performance of PE film, this phenolic resins sound insulating pad product of production can be made in mold cavity to produce bubble and make product produce lamination, causing product quality to decline, there is quality risk.
(2) due to noise enter the phenolic resins sound insulating pad of existing this structure after PE film on non-woven fabrics noise can be carried out reflecting to engine, now noise not decay, just bounce-back, the noise of engine bin is still very large, absorbs hot-tempered sound weak effect.
Utility model content
The purpose of this utility model overcomes when existing phenolic resins sound insulating pad is produced easily produce bubble and make product produce lamination, absorbs hot-tempered sound weak effect, there is the problem of potential safety hazard.
For this reason, the utility model provides a kind of phenolic resins sound insulating pad, comprise glass layer, the upper and lower surface of described glass layer is respectively arranged with nonwoven layer and lower nonwoven layer, sprinkled with PE bisque on described upper nonwoven layer and lower nonwoven layer and glass layer contact side one side.
Further, the thickness of described upper nonwoven layer and lower nonwoven layer is 0.8 ± 0.1mm.
Further, the surface density of described PE bisque is 20 ± 2g/m
2.
Further, the thickness of described phenolic resins sound insulating pad is 20 ± 2mm.
Further, the surface density of described phenolic resins sound insulating pad is 1050g/m
2± 10%.
The design principle of the utility model phenolic resins sound insulating pad is as follows:
PE bisque is owing to being granular structure, and the powder countless when noise enters can make noise produce diffuse reflection, and noise will successively weaken, and sound absorption qualities is greatly improved; In addition, because the sealing of PE film is fine, product can be made in mold cavity to produce bubble, product quality is declined, and PE powder does not have sealing, product thus can not be made to have quality risk.
The beneficial effects of the utility model:
(1) this phenolic resins sound insulating pad that the utility model provides can be basic elimination product on bubble and lamination.
(2) this phenolic resins sound insulating pad that provides of the utility model can the sound-absorbing effect of improving product significantly.
(3) this phenolic resins sound insulating pad that the utility model provides can eliminate safe hidden trouble thoroughly.
Below with reference to accompanying drawing, the utility model is described in further details.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model phenolic resins sound insulating pad.
Fig. 2 is the utility model phenolic resins sound insulating pad and existing sound insulating pad sound-absorbing effect comparison diagram.
Description of reference numerals: 1, glass layer; 2, upper nonwoven layer; 3, lower nonwoven layer; 4, PE bisque.
Detailed description of the invention
Embodiment 1:
Product is made to produce lamination in order to easily produce bubble when overcoming the production of existing phenolic resins sound insulating pad, absorb hot-tempered sound weak effect, there is the problem of potential safety hazard, present embodiments provide a kind of phenolic resins sound insulating pad as shown in Figure 1, comprise glass layer 1, the upper and lower surface of described glass layer 1 is respectively arranged with nonwoven layer 2 and lower nonwoven layer 3, sprinkled with PE bisque 4 on described upper nonwoven layer 2 and lower nonwoven layer 3 and glass layer 1 contact side one side.
Wherein, the thickness of above-mentioned upper nonwoven layer 2 and lower nonwoven layer 3 is 0.8 ± 0.1mm; The surface density of described PE bisque 4 is 20 ± 2g/m
2.
The integral thickness of this phenolic resins sound insulating pad is 20 ± 2mm, and the surface density of phenolic resins sound insulating pad is 1050g/m
2± 10%.
The concrete manufacture craft process of this phenolic resins sound insulating pad is as follows:
First, the top and bottom of glass layer 1 are added respectively nonwoven layer 2 and lower nonwoven layer 3 on one deck, sprinkled with one deck PE bisque 4 on the one side of upper nonwoven layer 2 and lower nonwoven layer 3, this layer structure material is put into mould.
Then, lathe rises and is closed up by mould, and mould design temperature is 220 DEG C, pressure is 13MP, and under this high-temperature and high-pressure conditions, pressurize 80s allows the material thermoplastic shaping in mould.
Again, taken out by the product of thermoforming, workman is by the finishing to aspects such as product deburring, boreholes.
Finally, after product finishing neat and tidy, be placed on after cubing platform verifies that all positions, hole are accurate, can put in storage.
This phenolic resins sound insulating pad makes PE membrane material into PE bisque, PE bisque is owing to being granular structure, the powder countless when noise enters can make noise produce diffuse reflection, noise will successively weaken, sound absorption qualities is greatly improved, overcome PE film only sound to be carried out reflecting to engine, now noise not decay, the problem of just bounce-back.In addition, because the sealing of PE film is fine, product can be made in mold cavity to produce bubble, product quality is declined, and PE powder does not have sealing, product thus can not be made to have quality risk.
This phenolic resins sound insulating pad provided by the present embodiment and existing phenolic resins sound insulating pad all carry out sound absorption test, and its test result as shown in Figure 2.In Fig. 2, transverse axis represents sound frequency, the longitudinal axis represents sound-absorbing proportionality coefficient (the higher expression sound-absorbing effect of coefficient is better), A line represents the sound-absorbing effect curve map of this phenolic resins sound insulating pad that the utility model provides, and B line represents the sound-absorbing effect curve map of existing phenolic resins sound insulating pad.As seen from Figure 2, this phenolic resins sound insulating pad of the present utility model improves the sound-absorbing effect of product significantly.
This phenolic resins sound insulating pad that the utility model provides can bubble on basic elimination product and lamination when producing, meanwhile, can the sound-absorbing effect of improving product significantly compared with existing sound insulating pad, thoroughly eliminate quality risk.
More than exemplifying is only illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection scope of the present invention with the same or analogous design of the utility model.
