The prepared PET composite material has the advantages of favorable gas barrier property, favorable impact resistance and excellent heat stability, and is suitable for preparing PET sheets in multiple electronic products.

Description

A kind of modified PET (Polyethylene Terephthalate) composite material
Technical field
The present invention relates to a kind of PET material, particularly relate to a kind of modified PET (Polyethylene Terephthalate) composite material, belong to plastic material technical field.
Background technology
Polyethylene terephtalate is a kind of important engineering plastics, it has excellent physical and mechanical properties in wide temperature range, under high-temperature high-frequency, still can keep excellent electrical insulation capability, be widely used in the every profession and trades such as electronics, food, medicine, office appliance, toy by the PET sheet that it is produced.But, there is barrier properties for gases difference in PET itself, crystallization is slow, shaping cycle is long, shock resistance is poor and the problem such as poor heat stability, limit it in very many-sided application, therefore certain modification need be carried out to PET material, to obtain the PET material meeting multiple application requiring.
In current art, the general performance being improved PET material by methods such as strengthening, fill, be blended.In recent years, along with the development of nanotechnology, people attempt adopting various technology to be added to by inorganic nano-particle in PET matrix, thus improve the crystal property of PET material, thermostability, shock strength and barrier properties for gases, but due to materials and the defect on improving one's methods, the effect realized is mostly unsatisfactory, and inorganic nano-particle particularly cannot be accomplished to be distributed to completely in PET matrix.Although some modification obtains good performance, the cost that preparation cost spends is very large, should not apply on a large scale.
 
Summary of the invention
For the demand, the invention provides a kind of modified PET (Polyethylene Terephthalate) composite material, this PET composite material adopts advanced nanotechnology and process for modifying surface to be prepared, production technique is simple, obtained PET composite material has good barrier properties for gases and shock resistance, excellent thermal stability, is particularly suitable for the making of multiple PET sheet in electronic product.
The present invention is a kind of modified PET (Polyethylene Terephthalate) composite material, and this matrix material is primarily of polyethylene terephthalate and calcium carbonate nano particle composition, and both mass percents are: polyethylene terephthalate 90%-95%: calcium carbonate nano particle 5%-10%.
In a preferred embodiment of the present invention, described polyethylene terephthalate and the mass percent of calcium carbonate nano particle are: 94%-95%:5%-6%.
In a preferred embodiment of the present invention, described calcium carbonate nano particle is mixed with by calcium oxide, polyoxyethylene glycol phosphoric acid ester 1000 and deionized water and forms.
In a preferred embodiment of the present invention, the raw materials of described polyoxyethylene glycol phosphoric acid ester 1000 is: cetomacrogol 1000 and polyphosphoric acid.
Present invention is disclosed a kind of modified PET (Polyethylene Terephthalate) composite material, the preparation of this composite material compositions is proper, advanced nanotechnology and process for modifying surface is adopted to be prepared, production technique is easy to implement, moderate cost, obtained PET composite material has the thermostability of good barrier properties for gases, shock resistance and excellence, is suitable for making the PET sheet in multiple electronic product.
 
Embodiment
Below preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The present invention mentions in modified PET (Polyethylene Terephthalate) composite material, and this matrix material is primarily of polyethylene terephthalate and calcium carbonate nano particle composition, and both mass percents are: polyethylene terephthalate 90%-95%: calcium carbonate nano particle 5%-10%.
Further illustrate, in this matrix material, the mass percent of polyethylene terephthalate and calcium carbonate nano particle is: 94%-95%:5%-6%; Calcium carbonate nano particle is mixed with by calcium oxide, polyoxyethylene glycol phosphoric acid ester 1000 and deionized water and forms; The raw materials of polyoxyethylene glycol phosphoric acid ester 1000 is: cetomacrogol 1000 and polyphosphoric acid.
Further illustrate, this matrix material take polyethylene terephthalate as matrix resin, with the calcium carbonate nano particle of surface modification treatment for stopping composition, is prepared by melt blending.Wherein, the mean diameter of calcium carbonate nano particle is 60nm, and it for surface treatment agent, adopts carborization to synthesize with polyoxyethylene glycol phosphoric acid ester 1000; Wherein, polyoxyethylene glycol phosphoric acid ester 1000 by mass percentage be 90% cetomacrogol 1000 and mass percentage be 10% polyphosphoric acid be prepared from; Active group is all contained in the two ends of the molecule of this nonionic surface active agent, and one end can form chemical bond with the surface of calcium carbonate nano particle, thus reduces the surface energy of calcium carbonate; The other end can with the end carboxyl of PET/hydroxyl generation esterification or etherification reaction, make the interface between PET and calcium carbonate nano particle, on molecular scale, chemical reaction occur, thus promote dispersed in PET of calcium carbonate, improve the crystal property of PET material, thermostability, shock strength and barrier properties for gases.Calcium carbonate nano particle in this modified PET (Polyethylene Terephthalate) composite material act as the insulation agent in PET thermal decomposition process, not only can suppress the thermolysis of PET, and the volatile products that PET thermolysis can be hindered to produce are overflowed from system, thus greatly improve the thermostability of PET material, through performance test analysis, the activation energy of this modified PET (Polyethylene Terephthalate) composite material thermolysis can reach 219.5KJ/mol.
Present invention is disclosed a kind of modified PET (Polyethylene Terephthalate) composite material, the preparation of this composite material compositions is proper, advanced nanotechnology and process for modifying surface is adopted to be prepared, production technique is easy to implement, moderate cost, obtained PET composite material has the thermostability of good barrier properties for gases, shock resistance and excellence, is suitable for making the PET sheet in multiple electronic product.
The above; be only the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the present invention; the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
