Description
Technical field
The invention belongs to technical field of polymer materials, print wrongly written or mispronounced character more particularly to a kind of high-glowing-filament-temperature flame-retardancy enhancing laser
PBT plastic and preparation method thereof.
Background technique
Polybutylene terephthalate (PBT), English name polybutylene terephthalate (abbreviation PBT) are a kind of
Thermoplastic polyester is developed in the last century initial stage seventies by Celanese company, the U.S..PBT has extraordinary and hot
Property, weatherability, chemical-resistant, and have many advantages, such as that excellent electric properties, water imbibition are small, surface is good, it is widely used
In the industries such as electric, automobile, machinery, household electrical appliance, especially electric industry.
Normally, electric industry has flame-retardancy requirements to material mostly, generally requires the whole nonflammable temperature of glowing filament
Up to 750 DEG C.The PBT material of early stage is modified by adding a large amount of fire retardant, and the whole nonflammable temperature of glowing filament can reach 750
℃.With the development of society, electronic product is increasingly intended to high-end development, European electronic product to the standard of PBT material journey again
A step is improved, 850 DEG C are risen to by original 750 DEG C to the nonflammable temperature of glowing filament.However, according to traditional improvement
Method continues to add fire retardant on PBT material of the nonflammable temperature of glowing filament up to 750 DEG C, although can make the glowing filament of PBT material not
Initiation temperature is up to 850 DEG C, but the mechanical property of material can completely lose, without practical application value.For example, existing use bromo
Triazine, antimony oxide, MCA fire retardant (Chinese name: melamine cyanurate) are compound, improve the flame retardant property of PBT material, but
The PBT material mechanical property of acquisition is excessively poor.Moreover, because fire retardant additive amount is big, pulvis is untreated to be directly added into, and is led
Processing technology is caused to be difficult to control.In addition, fire retardant duplicate type is few, flame retarding efficiency, glowing filament efficiency are low, therefore additive amount
Greatly, and brominated triazine it is expensive, lead to higher cost, be not suitable for practical application.
With the development of society, requirement of the mankind to environment is also higher and higher, environmental issue all becomes always everybody and pays close attention to
Topic, it is well known that ink printing industry environmental pollution is huge, and most of volatile solvent is all toxic or gas
Taste is very heavy.Currently, the consumer goods either industrial goods will have mark to distinguish or inform the characteristic of article.Traditional way
It is all to be printed by ink, it is that a time bomb has been buried to human health that this is invisible.Therefore, laser marking technology will be replaced
It is printed for traditional ink, is made into huge contribution for environmental protection.The PBT material for how developing a kind of suitable laser marking, at
For the hot issue of worker's concern in row.
