Abstract
The invention discloses a PVC (Polyvinyl Chloride) sole material with thermal stability. The PVC sole material comprises the following ingredients in percentage by weight: 60-65% of PVC, 25-30% of DBP (dibutyl phthalate), 0.1-0.2% of RH-208, 6-7% of CaCO3, and 2.8-3.9% of Ca-Zn thermal stabilizer. The Ca-Zn thermal stabilizer adding in the PVC sole material has good synergic stability effect, the long-time stability and ultraviolet aging resistance can be obviously improved.
Description
Technical field:
The present invention relates to footwear material technical field, relate in particular to a kind of PVC material for sole of shoe.
Background technology:
PVC is one of five large synthetic resins of in the world consumption maximum, is the linear polymkeric substance of thermoplasticity that is generated through Raolical polymerizable by vinyl chloride monomer.The PVC material has that intensity is high, cheap, chemical resistance is good, and electrical insulating property is good and be difficult to the advantages such as burning, is widely used in engineering construction, food product pack, electric and shoe industry.
When PVC is used for making sole, owing to containing branch point in the PVC polymer chain structure, the existence of the labile factors such as two keys and initiator residue, so that PVC molecule chlorosity is on the face easily deviate from from molecular chain, the characteristics that namely have poor heat stability, generally speaking, the PVC material for sole of shoe can decomposition discharge hydrogenchloride more than 100 ℃, prolongation along with the time, HCl deviates from a large number and is accumulated in the material, because HCl has katalysis to PVC degraded, thus the PVC degradation speed greatly accelerate, deviate from behind the HCl that a large amount of formation has the conjugated double bond of generation in the molecular chain, thereby the color of PVC material for sole of shoe is sharply deepened, and physical and mechanical properties descends.Therefore, when the machine-shaping of PVC sole, must use thermo-stabilizer.
The thermo-stabilizer that the PVC material is commonly used has lead salts thermo-stabilizer, organic tin thermo-stabilizer, antimony type thermal stabilizing agent, rare earth class thermo-stabilizer, calcium zinc heat stabilizer etc.Wherein lead salts thermo-stabilizer toxicity is large, has biological accumulation, has generated dust, and also can cause serious pollution to environment after discarded; The organic tin thermo-stabilizer has good thermostability and processibility, but manufacturing cost is high, can distribute certain peculiar smell in the course of processing, and part is poisonous; Antimony type thermal stabilizing agent is subjected to the uviolizing meeting that brown-black metachromasia occurs, and causes the anti-ultraviolet property of goods poor; Rare earth thermal stabilizer is because rare earth needs higher activation energy ability complexing chlorion, so that complex reaction speed is slow; For calcium zinc stabilizer, it is nontoxic, the environment protection thermal stablizer of generally acknowledging both at home and abroad at present, and in the PVC sole course of processing, the HCl reaction that the zn cpds in the calcium zinc heat stabilizer discharges after degrading with PVC generates ZnCl
2, be the catalyzer of PVC material for sole of shoe degraded, and calcium cpd can absorb HCl gas, also the unstable chlorine on the replaceable molecular chain plays the main stabilizer effect.
Summary of the invention:
The purpose of this invention is to provide a kind of thermostability PVC material for sole of shoe that has, the PVC sole that is made by this material has good thermostability and anti-ultraviolet ageing.
Purpose of the present invention is achieved through the following technical solutions:
A kind of high-wearing feature PVC material for sole of shoe comprises following component by weight percentage:
Preferred as technique scheme, described PVC content is 63-65%.
Preferred as technique scheme, described DBP is dibutyl phthalate, by the compound that carbon, hydrogen, oxygen element form, its chemical formula is C
16H
22O
4
Preferred as technique scheme, described RH-208 is that effect agent, a kind of trisiloxanes of modification are oozed in the organosilicon exhibition.
Preferred as technique scheme, described Ca-Zn thermo-stabilizer is less fatty calcium salt and the zinc salt of carbon number that is soluble in organic solvent, and main component has calcium stearate, ricinolic acid calcium, Zinic stearas, zinc ricinate and epoxy soybean oil, UV light absorber.
Beneficial effect of the present invention is: the Ca-Zn thermo-stabilizer of its adding has good collaborative stabilization, can significantly improve long-term thermal stability and anti-ultraviolet ageing.
