Description
Technical field
The utility model belongs to field of mechanical technique, be related to a kind of high leakproofness polypropylene seal bar processing method and its
Sealing strip.
Background technology
Polypropylene, be by propylene polymerization prepared by a kind of thermoplastic resin.It is divided into isotactic poly- third by methyl arrangement position
Alkene (isotactic polypropylene), random polypropylene (atactic polypropylene) and syndiotactic polypropylene
Three kinds of (syndiotactic polypropylene).
The same side that methyl is arranged in molecular backbone claims isotactic polypropylene, if the chaotic molecular backbone that is arranged in of methyl
Both sides claim random polypropylene, when the both sides that methyl is arranged alternately in molecular backbone claim syndiotactic polypropylene.It is poly- that general industry is produced
In allyl resin, isotactic structural content is about 95%, and remaining is random or syndiotactic polypropylene.Industrial products using isotactic thing be main
Composition.Polypropylene is also including the copolymer of propylene and a small amount of ethene.Usually translucent colorless solid, odorless is nontoxic.By
In compound with regular structure and highly crystallized, therefore fusing point may be up to 167 DEG C.Heat-resisting, corrosion-resistant, product can be its protrusion with moise-heat sterilization
Advantage.Density is small, is most light general-purpose plastics.Have the disadvantage that low-temperature impact resistance is poor, be easier to aging, but can be given respectively by modification
To overcome.
The PP materials of copolymer type have relatively low heat distortion temperature (100 DEG C), low transparency, low-luster, low rigidity, but
It is to have stronger impact strength, PP impact strength increases with the increase of ethylene contents.PP vicat softening temperature is
150℃.Because crystallinity is higher, the surface rigidity of this material and anti-scratch characteristic are fine.ESC is not present in PP
Problem.
PP melt mass flow rate (MFR) is generally 1~100.Low MFR PP materials impact property is preferable but prolongs
Open up intensity relatively low.For identical MFR material, the shock strength of copoly type is higher than homopolymerization type.Due to crystallization, PP contraction
Rate is at a relatively high, and generally 1.6~2.0%.
Polyacrylic crystallinity is high, compound with regular structure, thus with excellent mechanical property.Mechanical Properties of PP it is absolute
Value is higher than polyethylene, but still falls within relatively low kind in a plastic material, and its tensile strength only can reach 30MPa or slightly higher water
It is flat.The larger polypropylene of isotactic index has higher tensile strength, but with the raising of isotactic index, the impact strength of material has
Declined, but no longer change after dropping to a certain numerical value.
Temperature and loading speed are very big to polyacrylic Toughness.When temperature is higher than glass transition temperature, impact failure
In ductile rupture, significantly decline in brittle fracture, and impact value less than glass transition temperature.Loading speed is improved, can be made
The temperature that ductile rupture changes to brittle fracture rises.Polypropylene has excellent flexural fatigue resistance, and its product is at normal temperatures
Bent 106 times without damaging.
But under room temperature and low temperature, because the molecular structure regularity of itself is high, so impact strength is poor.Polypropylene
Most prominent performance is exactly flexural fatigue resistance, is commonly called as polypropylene (PP).Make it is therefore possible to use polypropylene material makes sealing strip
With.
But, existing polypropylene seal bar is usually single list structure, for than relatively large polypropylene seal
For bar, it is easily damaged in use.
The content of the invention
First purpose of the present utility model is that to improve its there is provided one kind in view of the above-mentioned problems existing in the prior art strong
