Specific embodiment
The present invention adds micron or nanoscale glass in the TPEE, and the additive amount of the glass is TPEE additive amount
1-10wt%。
The glass additive amount is the 5wt% of TPEE additive amount.
The micron or nanoscale glass are glass powder.
A kind of preparation method of the modified TPEE optical cable loose tube material of the glass of resistance to ultralow temperature, follows the steps below:
1) TPEE is divided into n parts, n is even number, and respective glass is separately added into every part of TPEE, is uniformly mixed, and forms n parts and mixes
Close object；
2) two two mixtures are mixed, is uniformly mixed, form n/2 parts of mixtures；
3) 2) step is repeated, a mixture is ultimately formed.
In TPEE and glass mixed process, first a part of TPEE is put into mixing kettle, then glass is filled with to mixing kettle
It is interior, a part of TPEE is then placed into, mixing is then stirred；
It is placed again into glass, is put into the TPEE of said mixture 0.3-0.7 thickness, is then stirred mixing again, and according to
This step is until mixing is completed.
Further explanation is made to the present invention below, to be better understood by goal of the invention of the invention:
The present invention is by TPEE, and the glass mixing of micron or nano-sized particles is used as filler, to improve hot property, the machine of TPEE
Tool performance and electric property, it is therefore intended that expand it in the application of industry and research field, there is excellent mechanicalness to obtain
It can be with broader use temperature range.
Adding proportion is as follows:
TPEE-GF1:GF/TPEE=1wt%；
TPEE-GF3:GF/TPEE=3wt%；
TPEE-GF5:GF/TPEE=5wt%；
TPEE-GF10:GF/TPEE=10wt%.
After Fig. 3 is it can be found that be added glass, the storage modulus of materialE' purer TPEE improves, this with before us
The extension test result of plane materiel material is consistent.It has been found that storage modulus increases obvious in low temperature range, in room temperature
More than, since storage modulus declines rapidly, the opposite amplification of composite material modulus also reduces therewith.Illustrate from this result, fills out
The mass of glass is filled under low temperature environment, to there is be more good prospect.
Glass fiber powder and polar TPEE have preferable compatibility to Electronic Speculum as the result is shown, and interfacial adhesion between the two is stronger
(Fig. 1, in 2 at arrow).And the intensity and modulus of glass fibre itself is higher, GF plays transmitting load and stress in the base
Role, therefore the intensity and modulus of composite material has certain promotion compared with pure TPEE.When GF dosage reaches 5wt%,
Start the agglomeration for occurring a small amount of；When dosage reaches 10wt%, there is stress concentration, therefore composite wood in agglomeration aggravation
The mechanical properties decrease of material.
Such result is very common in fiber filled polymer composite.Fiber filled polymer composite power
It learns performance to decline afterwards as the increased variation tendency of fiber loading usually first rises:, can be preferable when fiber content is lower
Ground disperses in the base, and the contribution of high-modulus improves the mechanical property of composite material；Fiber content is more than critical value, that is, understands shape
At the fiber aggregate of large scale, fault of construction caused by aggregate causes the mechanical property of composite material to deteriorate.
Fig. 4 is the stress-strain curve diagram of TPEE and composite material, and related data is listed in the following table.The addition of glass fiber powder mentions
The high yield strength of TPEE, " enhancing " act on the systems such as polypropylene/glass fiber, epoxy resin/glass fibre and all report
Road mistake.For fiber filled composite materials, draw ratio has a great impact to the intensity of composite material, theoretically comes
It says, " enhancing " effect of the big fiber of draw ratio is more significant.Glass fiber powder draw ratio used in this chapter and conventional glass fibers
Dimension has certain difference: its size is in micron level, and major diameter is smaller.TPEE and its composite material are as optical cable loose tube
In use, needing good flexibility.It is found in existing production practices, conventional glass fibre/polymer composites
With the increase of content of glass fiber, Transition of Brittleness is obvious, and in order to guarantee optical cable, internal glass fibre is not during bending
It is broken off, therefore glass fiber powder becomes preferable selection.
The related tension performance parameter of table TPEE and composite material
Upper table data are analyzed, the composite material yield strength of all components is all higher than pure TPEE, but yield strength is not much different.
In general, for glass fibre when content reaches a certain level in TPEE matrix, itself forms three-dimensional Percolation network structure, this
The formation meeting of kind structure is so that the performance of composite material reaches promotion.When the mass fraction of glass fiber powder is increased to by 1wt%
10wt%, yield strength do not increase further, illustrate how to disperse to become complicated in TPEE system in glass, will be rear
Continuous part holds a profound discussion.The elongation at break for the TPEE that do not have an impact is added in glass, this result is that within expectation
, because the lesser glass powder of draw ratio can't produce fracture under composite material bending, stretch behavior, to composite wood
The toughness of material will not generate apparent influence.The variation tendency of composite material modulus and the mass fraction of glass powder are consistent,
With the increase of glass powder content, rigid filled enrichment, orientation cause TPEE rigidly to become larger.
When glass powder mass fraction increases to 10wt% by 5wt%, may largely be reunited due to glass powder causes fracture strong
Degree and elongation at break decline, comprehensive performance deterioration.
In view of factors such as cost, mechanical performance and agglomerations, TPEE-GF5:GF/TPEE=5wt%, i.e. glass fiber content are selected
It is 5% for mass fraction.
