Abstract
The invention provides a production process of soundproof cotton. The production process comprises a cotton combing process, a melt-blowing net forming process, a covering process, an embossing and cutting process and a punching process. According to the production process of the soundproof cotton, polypropylene is melt-blown on a hollow polyester cotton roll to improve the strength of the soundproof cotton and ensure that the soundproof cotton can not be damaged easily during mounting and use, can not be aged easily and is good in weather resistance and long in service life. In the covering process of the production process of the soundproof cotton, a small amount of glue is uniformly sprayed on the surface of the hollow polyester cotton roll at first, then a non-woven fabric covering process is carried out, and a glue is added between the non-woven fabric and the hollow polyester cotton roll to ensure that the produced soundproof cotton is more stable and durable in structure, and the service life of the soundproof cotton is effectively prolonged.
Description
Technical field
The present invention relates to a kind of production technology, relate in particular to a kind of production technology of Sound-proof material.
Background technology
Hollow short dacron fiber, because of porose in fiber, has good sound insulation value, usings that this often uses hollow short dacron fiber as material in the production of Sound-proof material.But it is undesirable in the use procedure of Sound-proof material, also to exist intensity, the problems such as lightweight deficiency and sound insulation value have much room for improvement, with this, in the production process of Sound-proof material, should improve and solve for the problems referred to above, improving under the intensity of Sound-proof material and the prerequisite of sound insulation value, realizing the lightweight development of Sound-proof material.
Summary of the invention
The production technology that the object of this invention is to provide a kind of Sound-proof material solves that in the use procedure of the Sound-proof material existing in prior art, also to exist intensity undesirable, the problem that lightweight deficiency and sound insulation value have much room for improvement.
Technical solution of the present invention is:
A production technology for Sound-proof material, comprises the following steps:
A. carding step: hollow short dacron fiber is opened to bag through bale opener, and arrange through cotton feeder, carding machine that to form width be the hollow polyester lap that 1.5-2.1m, thickness are 3.5cm-6.4cm;
B. melt blown webbing operation: by after solid-state polypropylene liquefaction, take polypropylene and hollow polyester lap as 1:6-9 ratio evenly melts and sprays on hollow polyester lap surface, use lapper to become net to process on the hollow polyester lap after fusion-jetting polypropylene;
C. cover cloth operation: by being evenly sprayed on the surface of the hollow polyester lap after above-mentioned one-tenth net after the colloid liquefaction of solid, afterwards the hollow polyester lap after glue spraying is covered to the processing of cloth operation, be about to nonwoven and overlay on hollow polyester lap;
D. embossing cutting action: use embossing machine to carry out the processing of embossing operation on the hollow polyester lap covering after cloth, the hollow polyester lap after embossing is cut;
E. stamping procedure: for the Sound-proof material of needs lock seaming, device mould on hot stamping machine, carries out drop stamping to the material after cutting, forms Sound-proof material; Or for the Sound-proof material that does not need lock seaming, at cold stamping airborne device mould, the material after cutting is carried out to cold stamping, form Sound-proof material.
Further improve and be: in described melt blown webbing operation, polypropylene and hollow polyester lap are that 1:7 ratio evenly melts and sprays on hollow polyester lap surface.
The production technology of a kind of Sound-proof material of the present invention, by hollow polyester lap fusion-jetting polypropylene, improves the intensity of Sound-proof material, make Sound-proof material install and use procedure in cracky not, be difficult for agingly, weather resistance is good, long service life.Covering in cloth operation of the production technology of this kind of Sound-proof material, first the surface uniform at hollow polyester lap sprays a small amount of glue, then carrying out nonwoven is covering and is processing, because adding glue between nonwoven and hollow polyester lap, thereby make the stability of the Sound-proof material structure of production improve more than 30%, more firmly durable, effectively extended service life of Sound-proof material.
In the stamping procedure of the production technology of this kind of Sound-proof material, divide and have drop stamping and Cold Press Working, Sound-proof material for needs lock seaming carries out drop stamping, do not need the Sound-proof material of lock seaming to carry out cold stamping, cold stamping is not simultaneously because needing lock seaming, therefore can single multilayer punching press, thereby enhance productivity.The production technology of this kind of Sound-proof material, flow scheme design is reasonable, under the prerequisite of quality that guarantees Sound-proof material, production efficiency is high, and this kind of production technology gained Sound-proof material outward appearance is clean and tidy, good in broad frequency range internal sound insulation performance and sound absorption qualities, sound insulating and absorbing performance long time stability, be applicable to automobile and can not make vehicle body deadweight increase too much, avoided increase oil consumption.
The Sound-proof material of this kind of production technology gained is applicable to automobile, can be by the grating of the resonance of engine noise, vibrations, vehicle body car door, when driving and road surface, air drag generation etc., effectively eliminate and intercept, thereby form a quiet driving space, improve greatly the comfortableness of driving.This kind of production technology gained Sound-proof material is applied to automobile and can strengthens vehicle body simultaneously, all weaker for non-key position fabrication iron sheet in vehicle body machine cover, car door, standby cabin, roof, beater or beat-up, install additional after this kind of production technology gained Sound-proof material, vehicle body is firmer, while bumping, passive security coefficient is improved.And can optimize the acoustics of automobile, particularly rear-mounted subwoofer, can cause back in-support carriage vibration, and audio reduces, and this is that the structure of automobile cannot be born the impact of mega bass because do not do appropriate damping, send " " sound.After Sound-proof material construction, eliminated the resonance of vehicle body metal, there is again good sound absorption simultaneously, can feel that sound equipment is more clear, simple and honest, surge.
The invention has the beneficial effects as follows: the production technology of a kind of Sound-proof material of the present invention, by hollow polyester lap fusion-jetting polypropylene, improves the intensity of Sound-proof material, make Sound-proof material install and use procedure in cracky not, be difficult for agingly, weather resistance is good, long service life.Covering in cloth operation of the production technology of this kind of Sound-proof material, first the surface uniform at hollow polyester lap sprays a small amount of glue, then carrying out nonwoven is covering and is processing, because adding glue between nonwoven and hollow polyester lap, thereby make the Sound-proof material structure of production more firmly durable, effectively extended the service life of Sound-proof material.
