Abstract
The invention provides and the invention discloses a kind of nucleating agent in polylactic acid production composition and application thereof, said composition main ingredient comprises: Phenylphosphine hydrochlorate and stearate.The application of said composition: said composition and polylactic resin are mixed the crystal property that melting mixing effectively can improve poly(lactic acid).The invention has the beneficial effects as follows: the nucleating agent in polylactic acid production of more single Phenylphosphine hydrochlorate, this nucleating agent in polylactic acid production composition nucleator overcomes single nucleator can only provide nucleus, the shortcoming promoting molecular arrangement can not be met, further increase the efficiency of nucleator, accelerate the crystallization rate of poly(lactic acid), improve the degree of crystallinity of poly(lactic acid).
Description
Technical field
The present invention relates to a kind of nucleating agent in polylactic acid production composition and application thereof, belong to poly(lactic acid) auxiliary agent technical field.
Background technology
In recent years, be that biomass or the biodegradable plastic development of theory is rapid with low-carbon environment-friendly, wherein the representational kind of most is poly(lactic acid).The advantages such as poly(lactic acid) has high strength, high-modulus, but the crystallization rate simultaneously caused by structure and the low subject matter being its restriction and developing of degree of crystallinity.
The method that nucleator is the most effective its crystallization rate of raising and degree of crystallinity is added in poly(lactic acid).At present, nucleator kind mostly is single inorganic materials and organic compound kind and macromolecular material, rarely has report for compound kind.The nucleator of single variety often cannot play optimal efficacy, and cause polylactic acid crystal speed low, the process-cycle is long, and degree of crystallinity is low, causes the poor heat resistance of polylactic acid article, affects result of use.
Summary of the invention
The object of the invention is to overcome the defect and a kind of nucleating agent in polylactic acid production composition of providing and application thereof that above-mentioned prior art exists.
A kind of nucleating agent in polylactic acid production composition, this nucleating agent compositions main ingredient comprises Phenylphosphine hydrochlorate and stearate.
As preferably, in this nucleating agent compositions, described Phenylphosphine hydrochlorate and the massfraction proportioning of stearate are: 0.5:1-2:1.
Described Phenylphosphine hydrochlorate metal ion is calcium, magnesium, barium, zinc, the combination of one or more in aluminium, lithium.
Described stearate metallic ion is calcium, magnesium, barium, zinc, the combination of one or more in aluminium, lithium.
The application of nucleating agent in polylactic acid production composition of the present invention: said composition is mixed melting mixing with polylactic resin.
By the addition in said composition and polylactic resin be: the mass percent of 1%-2%.
Feature of the present invention is: the nucleating agent in polylactic acid production of more single Phenylphosphine hydrochlorate, this nucleating agent in polylactic acid production composition nucleator overcomes single nucleator can only provide nucleus can not meet the shortcoming promoting molecular arrangement, further increase the efficiency of nucleator, accelerate the crystallization rate of poly(lactic acid), improve the degree of crystallinity of poly(lactic acid).
Embodiment
Below in conjunction with specific examples, the present invention will be further described in detail.
Sample preparation
The present invention aims to provide a kind of nucleating agent in polylactic acid production composition and application thereof.By selecting different Phenylphosphine hydrochlorates and stearate and the composite of different ratios to obtain a kind of nucleating agent in polylactic acid production composition, composite mode uses known composite mode.
By poly(lactic acid) (trade(brand)name: Ingeo 4032D) and nucleator (composition of phenyl-phosphonic acid zinc and stearate) empirically ratio put in torque rheometer (Shanghai Kechuang rubber and plastics machine equipment company limited) and mix melting mixing (180 DEG C, 80rpm, 5min).
Sample preparation ratio is as shown in table 1:
Table 1
Performance test
Below by way of embodiment more specific description the present invention of performance test.The present invention evaluates Tc and degree of crystallinity by differential scanning calorimeter (DSC).
Tc: the peak temperature heat release caused by the crystallization by the polylactic resin occurred in cooling reached is as Tc, and Tc is higher, and crystallizing power is stronger.
Degree of crystallinity: using the investigation result of the heat release enthalpy caused by the crystallization by the polylactic resin occurred in cooling as degree of crystallinity, enthalpy is larger, and degree of crystallinity is larger.
To each sample prepared by sample preparation link, use differential scanning calorimeter (DSC, plum Teller-Tuo benefit), adopt following programsegment to evaluate Tc and degree of crystallinity.
Programsegment: rise to 210 DEG C of insulation 3min with the speed of 20 DEG C/min from 25 DEG C, be cooled to 25 DEG C with-10 DEG C/min, then rise to 210 DEG C with the speed of 20 DEG C/min from 25 DEG C.Test result is as table 2
Table 2
Programsegment: rise to 200 DEG C of insulation 5min with the speed of 10 DEG C/min from 25 DEG C, be cooled to 25 DEG C with 2 DEG C/min, test result is as table 3
Table 3
Experimental result shows: as can be seen from test result, nucleating agent in polylactic acid production composition provided by the invention all more single phenyl-phosphonic acid zinc nucleator, the degree of crystallinity of polylactic resin is improved, accelerate the crystallization of poly(lactic acid), being conducive to the polylactic resin process-cycle shortens, improve the thermotolerance of polylactic acid article, be conducive to improving result of use.
It is phenyl-phosphonic acid zinc that the present invention provide only described Phenylphosphine hydrochlorate, described stearate is Zinic stearas, calcium stearate, the embodiment of lithium stearate, but it is known in conjunction with knowledge well known in the art: metal ion is calcium, magnesium, barium, zinc, aluminium, the Phenylphosphine hydrochlorate of the one or more combination in lithium is similar to phenyl-phosphonic acid zinc character, metal ion is calcium, magnesium, barium, zinc, aluminium, the stearate of the one or more combination in lithium and Zinic stearas, calcium stearate, lithium stearate character is similar, therefore embodiment of the present invention is not applied to limit the scope of the invention.
The above is only better embodiment of the present invention, therefore all equivalences done according to feature described in patent claim of the present invention and principle change or modify, and are included in patent claim of the present invention.
