Description
Technical field
The present invention relates to polymeric material field more particularly to a kind of glazed flame-retardant polypropylene materials with aesthetic effect
Material.
Background technology
Low-carbon environment-friendly has become one main trend in the world, and the related environmental protection act of various countries emerges one after another, this
Under big environmental background, the new technology of various low-carbon environment-friendlies has obtained the favor of more and more consumers.Wherein, one-time formed
Exempt from spraying aesthetic resin because it is without post-processing, beautiful appearance is not only brought to product, but also greatly reduce production link and cause
Environmental pollution, receive the concern of more and more people.
But compared with Traditional paint spray and plating, exempting from spraying aesthetic resin has the shortcomings that it is difficult to overcome, i.e., in structure
On complicated product, weld mark and current mark are easy tod produce, while effect exquisiteness degree is higher, defect is also more serious.On just because of
Reason is stated, exempts from spraying aesthetic resin and is difficult to use on high-grade household electrical appliances, consumer electronics and auto parts machinery.
Weld mark and current mark Producing reason are different.The generation of weld mark is mainly due to several in injection moulding process
Stock material stream shunts in a mold to be converged, and melt is unable to welding and is integrated each other in interface incomplete fusion, and fusion is caused to print
Mark；Weld mark solves the welding angle increased as possible when stream is converged that on the one hand can start with from optimization mould structure design,
On the other hand can from improve high molecular material segment locomitivity start with improve melt interface degree of fusion, to reach
To the purpose of reduction weld mark.The generation of current mark mainly due to metallic aluminium powder pigment and plastic basis material associativity it is bad, with
It is easy to happen curling and overturning when plastic melt flows or in Liang Gu melts intersection, aluminium powder rareness leads to product table at clinkering
Local reflex ability in face declines, to generate apparent current mark in article surface；The solution of current mark is mainly from raising metallic aluminium powder
Start with the compatibility aspect of plastic basis material, but general technological means is difficult to effectively improve the compatibility of aluminium powder and base material.
At the same time, polypropylene is very easy to burning, is unable to self-extinguishment after catching fire in air, easy tos produce fire hazard.
Therefore, effective it is necessary to be carried out to polypropylene material to meet requirement of the electronic and electrical equipment to polymer material flame retardant property
It is flame-retardant modified.In addition, in fields such as electric, household electrical appliances, used plastic material does not need only to have certain anti-flammability
Can, and also need to have the characteristics that the fire retardant low, glossiness is high, appearance looks elegant, heat resistance are good but traditional is precipitated in surface
System often easily brings harmful effect to the above-mentioned performance of material.
