Abstract
The invention discloses a biodegradable polyester composition. On the basis of the total weight of the biodegradable polyester composition, the weight content of tetrahydrofuran is 3-200 ppm. By adding tetrahydrofuran in the composition, the content of tetrahydrofuran in the composition is controlled to be within the range of 3-200 ppm, the bad printing phenomenon of the biodegradable polyester composition in the printing process can be greatly improved, the phenomenon that printing ink disengages from a film material is avoided, the phenomenon that because printing ink is too much, the printing ink adheres to the film material is also avoided, and therefore a thin film has good printing performance.
Description
Technical field
The invention belongs to polymer modification field, be specifically related to a kind of can falling by biology of excellent printing performance that haveSeparate polymer blend.
Background technology
Biodegradable polyester is the family macromolecule material taking living resources as raw material. With respect to taking petrochemical industry resource as formerThe petroleum base macromolecule of material, Biodegradable polyester can or occur in biotic environment in biology or biological chemistry action processDegraded, is very active in current biodegradable plastic research and one of best degradable material is applied in market.
Biodegradable polyester film is one of current Biodegradable polyester important applied field, mainly comprises foodBag, refuse bag, shopping bag and mulch film etc. Biodegradable polyester is prepared in the process of film in blowing, conventionally needs China ink, fromAnd on film, print label and the mark of demand. But usually there is printing not in Biodegradable polyester film in printing processJail (ink does not stick on film completely, or adhesion strength is inadequate) or print excessive situation (ink adhesion is too much, mark notClearly), the printing performance of film is poor.
The present invention surprisingly finds after deliberation, in Biodegradable polyester composition, by adding micro-tetrahydrochysene furanMutter, can make film material in printing process, both there will not be ink to depart from the phenomenon of film material, also there will not be settling off to adhere toThe phenomenon of film material, thus make film show good printing performance.
Summary of the invention
The object of the present invention is to provide a kind of Biodegradable polyester composition, by add trace in said compositionOxolane, can make the Biodegradable polyester composition preparing there is excellent printing performance.
The present invention is achieved by the following technical solutions:
A kind of Biodegradable polyester composition, by weight, comprises component:

Iv) the copolymerization that contains epoxide group and styrene-based, acrylate and/or methacrylate of 0.02 to 0.5 partThing.
Described biodegradable aliphatic-aromatic polyesters is poly-adipic acid mutual-phenenyl two acid bromide two alcohol ester PBAT, poly-amberOne or more in acid mutual-phenenyl two acid bromide two alcohol ester PBST or poly-decanedioic acid mutual-phenenyl two acid bromide two alcohol ester PBSeT.
Tetrahydrofuran THF adds in Biodegradable polyester composition, can play the effect of similar lubricant, thisBrightly find by research, the content of the oxolane in Biodegradable polyester composition is controlled to 3ppm-200ppm, canMake the dynamic friction factor of film material in zone of reasonableness, make film material in printing process, both there will not be ink to depart from the phenomenon of film material(printing is not firm), also there will not be the phenomenon of settling off adhesive film material, thereby makes film show good printing performance.If but tetrahydrofuran THF content is too high in Biodegradable polyester composition, film dynamic friction factor is minimum, substantially cannot realizePrinting; Tetrahydrofuran THF content is too low, and dynamic friction factor is too large, occur in printing process, and the too much situation of the sticky China ink of film, because ofThis gross weight based on Biodegradable polyester composition, the weight content of oxolane is preferably 8ppm-100ppm, more preferablyFor 15ppm-75ppm.
Described organic filler is selected from a kind of in native starch, plasticized starch, modified starch, natural fiber or wood powder or itsMixture; Described inorganic filler is selected from talcum powder, imvite, kaolin, chalk, calcium carbonate, graphite, gypsum, conductive black, chlorineChange in calcium, iron oxide, dolomite, silica, wollastonite, titanium dioxide, silicate, mica, glass fibre or mineral fibresA kind of or its mixture.
The acquisition approach of cyclic ester compound of the present invention, can pass through at Biodegradable polyester composition blending extrusionIn the process of processing, directly add oxolane.
According to different purposes needs, Biodegradable polyester composition of the present invention can also further add 0 to 4 partAt least one following substances: plasticizer, releasing agent, surfactant, wax, antistatic agent, dyestuff, UV absorbent, UV are stableAgent or other plastic additives.
Described plasticizer is a kind of or two kinds and the above mixture in citrate, glycerine, epoxy soybean wet goods;
Described releasing agent is a kind of or two kinds and the above mixture in silicone oil, paraffin, White Mineral Oil, vaseline;
Described surfactant is a kind of or two kinds and the above mixing in polysorbate, palmitate or laurateThing;
