Abstract
The invention relates to a plasticizer for PVC. The plasticizer comprises, by mass, 20 to 50 parts of a polyester polymer, 5 to 45 parts of a polyethylene polymer and 0.1 to 100 parts of biological molecules, wherein the polyester polymer is polyhydroxyvalerate, polyhydroxyvaleric acid or a copolymer of polyhydroxyvalerate and polyhydroxyvaleric acid, the polyethylene polymer comprises polyvinyl acetate, polybutylenesuccinate, polyvinyl alcohol, poly-p-dioxanone and a copolymer of the above-mentioned components, and the biological molecules comprise one or a mixture of the components in a group consisting of vegetable gelatin, animal protein, chitin and hyaluronic acid. The invention is advantaged in that the plasticizer for a PVC material provided by the invention can enhance flexibility, elasticity and surface strength of the PVC material, thereby allowing an application scope of the PVC material to be wider.
Description
Technical field
The present invention relates to a kind of plastics technology field, the softening agent of using in especially a kind of PVC material.
Background technology
PVC (SE) is the chlorine polymkeric substance of PE (Vilaterm), one of plastics that the amount of being to use is bigger, and now still in a large amount of uses, its consumption is only inferior to Vilaterm and Vestolen PP 7052.The goods form of SE is very abundant, can be divided into rigid polyvinyl chloride, flexible PVC, PVC paste three major types.Rigid polyvinyl chloride is mainly used in extruded products such as tubing, door-window section bar, sheet material, and moulding such as tube stub, electric parts and extrude the bottle series products that blows type, and they account for the consumption of SE more than 65%.Flexible PVC is mainly used in calendared sheet, automotive trim article, handbag, film, electric wire, medical product etc.
Along with the continuous development of human society, human environment consciousness strengthens gradually, and the theory of Sustainable development is arisen at the historic moment.People require increasingly high to the feature of environmental protection of plastic material, but general material structure itself is difficult for upgrading, have via product after all kinds of processing treatment to be prone to defectives such as crisp, poor heat resistance, viscosity are not enough, so the application surface of material have received limitation.
Summary of the invention
In order to overcome above defective, the technical problem that the present invention will solve is: the softening agent that proposes a kind of stable snappiness, elasticity and condition of surface that can the Reinforced PVC material.
The technical scheme that the present invention adopted is: a kind of PVC uses softening agent, and said each component and mass fraction do
20～50 parts of polyester polymers,
35～45 parts of polyethylene based polymers,
0.1～100 part of biological molecule.
According to another preferred embodiment, a kind of PVC uses softening agent to comprise that further said polyester polymer is to gather hydroxyl valerate, gather hydroxypentanoic acid or their multipolymer.
According to another preferred embodiment, a kind of PVC uses softening agent to comprise that further the content of hydroxyl in the said polyester polymer is 15～30%.
According to another preferred embodiment, a kind of PVC comprises further that with softening agent said polyethylene based polymers comprises Yodo Sol VC 400, poly-succinic fourth diester, Z 150PH, gathers p-dioxanone or its multipolymer.
According to another preferred embodiment, a kind of PVC comprises further that with softening agent said biological molecule comprises a kind of or its mixture in vegetalitas gelatin, animal protein, chitin and the Hyaluronic Acid.
According to another preferred embodiment; A kind of PVC uses softening agent to comprise that further said preparation method is: in 180 ℃～350 ℃ TR, be placed on polyester polymer, polyethylene based polymers and biological molecule fully to stir in the reactor drum and got product in 5～60 minutes.
The invention has the beneficial effects as follows: propose a kind of PVC material and use softening agent, snappiness, elasticity and surface strength that it can the Reinforced PVC material, thus make that the range of application of PVC material is more extensive.
Embodiment
A kind of PVC uses softening agent, and said each component and mass fraction do
20～50 parts of polyester polymers,
35～45 parts of polyethylene based polymers,
0.1～100 part of biological molecule.
Among the present invention, said polyester polymer is to gather hydroxyl valerate, gather hydroxypentanoic acid or their multipolymer, and the content of hydroxyl is 15～30% in the wherein said polyester polymer.
Among the present invention, said polyethylene based polymers comprises Yodo Sol VC 400, poly-succinic fourth diester, Z 150PH, gathers p-dioxanone or its multipolymer.
Biological molecule is meant the material with biodegradable or biological compatibility, and biological molecule of the present invention mainly comprises a kind of or its mixture in vegetalitas gelatin, animal protein, chitin and the Hyaluronic Acid.The purposes of this biological molecule is toughness, shock strength, tack or the ductility that is used for adjusting biodegradable polymers.
PVC of the present invention uses the preparation method of softening agent to be: in 180 ℃～350 ℃ TR, be placed on polyester polymer, polyethylene based polymers and biological molecule fully to stir in the reactor drum and got product in 5～60 minutes.
Further specify below in conjunction with specific embodiment.
Embodiment 1
Get and gather 35 parts of hydroxyl valerates, 45 parts of Yodo Sol VC 400 and 20 parts of animal proteins add in the reaction vessel, are controlled at temperature in 180 ℃～350 ℃ the scope, fully stir 5～60 minutes, get product.
Embodiment 2
Gather hydroxypentanoic acid 50,45 parts of poly-succinic fourth diester and 5 parts of animal proteins add in the reaction vessel, are controlled at temperature in 180 ℃～350 ℃ the scope, fully stir 5～60 minutes, get product.
Embodiment 3
Get and gather 45 parts of hydroxyl valerates, 45 parts of poly-succinic fourth diester and 10 parts of animal proteins add in the reaction vessel, are controlled at temperature in 180 ℃～350 ℃ the scope, fully stir 5～60 minutes, get product.
In sum, snappiness, elasticity and surface strength that softening agent of the present invention can the Reinforced PVC material, thus make that the range of application of PVC material is more extensive.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification sheets, must confirm its technical scope according to the claim scope.
