Abstract
The invention discloses a kind of highly endothermic high brightness bottle-grade polyester chips, belong to polyester slice technical field.The highly endothermic high brightness bottle-grade polyester chip contains titanium nitride and barium sulfate in polyester slice, and weight content of the titanium nitride in polyester slice is 5~30ppm, and weight content of the barium sulfate in polyester slice is 1~5ppm.The present invention is by the way that titanium nitride and barium sulfate are added in polyester slice, to have of light color, transparency height again while improving bottle-grade polyester chip and absorbing infrared heating energy, acetaldehyde is low, intensity is high, and splitting resistance is good, good toughness, good barrier property, the features such as processing convenient for rear road.
Description
Technical field
The invention belongs to polyester slice technical fields, and in particular to a kind of highly endothermic high brightness bottle-grade polyester chip.
Background technique
Polyester is the general name with polyethylene terephthalate (PET) for the thermoplastic novolac saturated polyester of representative, it
An important use be for food packaging applications.PET both can be made into biaxial tension packaging film when as packaging material for food,
It can be made into after amorphous state bottle base to be blow molded again again and high-intensitive, high transparency stretch blow bottle be made, can also directly extrude in flakes
Hollow container is made in thermoforming again after material.PET product has transparent, oil resistant, protects fragrant, health is reliable and use temperature range is wide etc.
Performance, therefore constantly increase in the dosage of packaging field.
It required to be heated to glass transition temperature or more before bottle base is blow molded into bottle, general heating uses far-infrared lamp
Heating device.A small amount of far infrared absorbing material is added in a slice, can be mentioned in the case where having substantially no effect on bottle appearance
High bottle base Far-infrared Absorption ability improves production efficiency to reduce the energy consumption for blowing bottle.The economic rapid growth in China, Ge Xiangjian
If obtaining great achievement, but huge resource is also paid and cost that environment is destroyed, the contradiction between the two is increasingly sharp
It is sharp, masses' environmental pollution strong reaction.This situation is directly related with irrationality of the economic structure, extensive pattern of economic growth.
Do not accelerate to adjust economic structure, growth pattern transformation, resource branch is unable to hold out, and environment does not accommodate, and society, which holds, dares not accept, economy hair
It opens up hard to carry on.Therefore the product of low energy consumption is following developing direction.
There is Far-infrared Absorption polyester slice currently on the market, but since such product is all the material using carbon black class
As Far-infrared Absorption agent, to reach satisfied energy-saving effect and need biggish additive amount, on the color value of polyester slice influence compared with
Greatly.Therefore, it is necessary to be changed while improving the energy-saving effect of polyester slice slice by adding novel Far-infrared Absorption agent
The color value of kind slice, improves the brightness of final products, expands the application field of the product.
Summary of the invention
The present invention is directed to the situation of the prior art, overcomes above-mentioned technological deficiency, and it is poly- to provide a kind of highly endothermic high brightness bottle grade
Ester slice.
The present invention uses following technical scheme, and the highly endothermic high brightness bottle-grade polyester chip contains in polyester slice
Titanium nitride and barium sulfate, weight content of the titanium nitride in polyester slice are 5~30ppm, weight of the barium sulfate in polyester slice
Amount content is 1~5ppm.
As a further improvement of the above technical scheme, the polyester slice inherent viscosity is 0.8~0.9dl/g；Nitridation
Weight content of the titanium in polyester slice is 3~15ppm；Weight content of the barium sulfate in polyester slice is 1~3ppm.
As a further improvement of the above technical scheme, weight content of the titanium nitride in polyester slice be 5~
8ppm；Weight content of the barium sulfate in polyester slice is 0.5~1ppm.
Highly endothermic high brightness bottle-grade polyester chip disclosed by the invention, the beneficial effect is that, the present invention is by poly-
Titanium nitride and barium sulfate is added in ester slice, to have while improving bottle-grade polyester chip and absorbing infrared heating energy again
Have of light color, transparency is high, and acetaldehyde is low, intensity is high, and splitting resistance is good, good toughness, good barrier property, convenient for rear road processing etc.
Feature.
Specific embodiment
The invention discloses a kind of highly endothermic high brightness bottle-grade polyester chips, below with reference to preferred embodiment, to the present invention
Specific embodiment be further described.
The highly endothermic high brightness bottle-grade polyester chip, contains titanium nitride and barium sulfate in polyester slice, and titanium nitride exists
Weight content in polyester slice is 5~30ppm, and weight content of the barium sulfate in polyester slice is 1~5ppm.
Preferably, the polyester slice inherent viscosity is 0.8~0.9dl/g；Weight of the titanium nitride in polyester slice contains
Amount is 3~15ppm；Weight content of the barium sulfate in polyester slice is 1~3ppm.
Preferably, weight content of the titanium nitride in polyester slice is 5~8ppm；Barium sulfate is in polyester slice
Weight content is 0.5~1ppm.
For a person skilled in the art, technical solution documented by foregoing embodiments can still be repaired
Change or equivalent replacement of some of the technical features, it is all within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should be included in protection scope of the present invention.
