Description
Technical field
The present invention relates to auto parts and components manufacture fields, and in particular to a kind of raising is comprehensive with PET felts in felt wheelhouse
The method for closing performance.
Background technology
Domestic Automotive Industry growth momentum was powerful in recent years, and China has become the third automobile after beautiful, day and produces per year
Broken ten million country, into ten million automobile superpower ranks.
With the development of economy with the raising of personal family income, automobile has been not only doing for organ and business unit
Tool that is public and riding instead of walk, automobile have become the first choice of current household consumption, and people are in addition to the brand, safety and matter for automobile
Outside amount is put forward higher requirements, more pay attention to the comfort driven, the especially requirement to automobile component sound insulation and decrease of noise functions
It is higher and higher.
Automobile wheelhouse rigging position is mainly to play sound insulation and noise reduction at the metal plate of automobile tire upside.Traditional vapour
Vehicle wheelhouse is broadly divided into three classes, and the first kind is integral heat pressure felt wheel cover, such wheel cover moulding process is simple, it is light-weight, make an uproar
Sound is low, the disadvantage is that efficiency is low, service life is short, and current such product is widely used in most of low side vehicle in the market；Second
Class is common injection-molded plastic wheel cover, its main feature is that product size is stable, light-weight, service life is long, the disadvantage is that noise is big；
Third class wheel cover be on the basis of first two wheel cover, by process innovation come single injection-molded band felt wheelhouse.
Since wheel of the noise source in traveling of wheelhouse causes rubble to strike phenomenon, rubble impact concentrated area is known
Not, the advantages of and combining first two wheelhouse in being molded wheelhouse forming process, is struck in rubble and is collected by technological innovation
Middle region is inlaid into PET felts.The advantages of this kind of wheelhouse is：Product size is stable, light-weight, low noise, at present by
Step is applied in some high-end vehicles.The band felt wheelhouse of this single injection-molded is not permitted due to more demanding to appearance
Permitted phenomena such as fold, seep through occur, and melt does not allow to be penetrated into PET felts when embedding and injection molding, therefore to the rigid of PET felts
The requirement of degree and tensile property is very high, while also requiring it with stronger resistance to rubble impact.However, in actual production
Cheng Zhong, rigidity, tensile resistance and the resistance to rubble impact of generally existing PET felts can not ensure simultaneously, stable quality
The defects of property is poor.
Invention content
In view of the deficiencies of the prior art, it is an object of the present invention to provide PET felts in a kind of raising band felt wheelhouse are comprehensive
The method for closing performance.This method carries out rational weight proportion by using different physical characteristics PET fiber and optimizes PET maos
The processing technology of felt makes the bending stiffness, tensile resistance and resistance to rubble impact of PET felts be satisfied by requirement, ensures production
Quality stability.
To achieve the above object, the present invention is achieved through the following technical solutions：
A method of it improves with PET felt comprehensive performances in felt wheelhouse, specifically includes following steps：
Step S1, raw material is chosen：
The PET fiber 25%-40% of fineness 6D
The PET fiber 15%-30% of fineness 1.5D
The LPET fibers 40%-50% of fineness 4D, 135 DEG C of fusing point
Step S2, the processing of PET felts：Ware-house-in inspection, storage are carried out to raw material, required according to raw material proportioning uniformly flat
It is layered on convoying curtain；Then it uses opener shredding to handle, after mixed cotton, cotton carding, crosses needle bundle eedle and be bundled into blanket, Zhi Houjuan
It takes, crosses baking oven, the sizing of normal temperature circulation water cooling, cut-parts, shape by die-cutting；Wherein, when the needle is bundled into blanket control it is pre- prick 14 ±
1mm, it falls to prick 9 ± 1mm, just prick 9 ± 1mm；Oven temperature is set when the baking oven excessively：205 ± 6 DEG C, baking oven effective length：4m、
Delivery rate：2m/min.
As a preference of the present invention, matched by following when the step S1 raw materials selection,
The PET fiber 30%-40% of fineness 6D
The PET fiber 15%-20% of fineness 1.5D
The LPET fibers 45%-50% of fineness 4D, 135 DEG C of fusing point.
The advantages and positive effects of the present invention：PET felts provided by the invention are by using different physical characteristics PET fiber
Carry out rational weight proportion, and complete after rolling, high temperature fast shaping, truncation molding, have it is simple and reasonable,
It is easy to process, sound insulation and noise reduction effect is good, resistance to rubble impact property is good, corrosion resistance and good, water resistance is good, it is anti-to meet simultaneously
The advantages that tensile property and bending stiffness performance, effectively solving existing PET felts can not ensure that tensile resistance, bending resistance are rigid simultaneously
Degree and resistance to rubble impact, the technical barrier of quality stability difference.
