Description
Technical field
The present invention relates to modifying plastics technical field, particularly relate to a kind of high gloss halogen-free flame retardant PC/ABS alloy material and preparation method thereof.
Background technology
At present, people mainly concentrate on the features such as outer perception is good, light weight to the requirement of glazed plastic product, but the raising to fire safety consciousness along with expanding economy and people is more and more higher to the requirement of the flame retardant properties of plastic prod and use cost.Raising day by day along with human consumer's individual demand, and an urgent demand that reduces system cost, the production firm of electronic enterprises is faced with stern challenge: material therefor that household electrical appliances wait is environmental protection more not only, and material should meet more harsh application standard at aspects such as security and processing characteristicies.
The synergistic system of flame-retardant modified most employing halogenated flame retardant and antimony compounds, material forms toxic compounds when burning or thermo-cracking (even high temperature process), and corrosive gases and volume of smoke are very large to human body and environmental hazard.On July 1st, 2006, the < < of European Union ROHS > > is formally effective, and established part brominated flame-retardant can not be used on the product of engineering plastics.Low-carbon (LC), environmental protection " theory is rooted in the hearts of the people, and increasing human consumer is at choice for use halogen-free electronic product.Nontoxic, environmental protection, halogen-free flameproof substitute gradually the fire-retardant direction of flame retardant products development in the world that becomes of halogen, becomes the emphasis of various countries' exploitation.At present, in Chinese industrial, flame retardant products nearly 80% used is that Halogen is fire-retardant.China must greatly develop the development trend that halogen-free flameproof product could adapt to world market.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of high gloss halogen-free flame retardant PC/ABS alloy material, make it have outward appearance good, use safe performance, can be widely used in field of household appliances; Another object of the present invention is to provide the preparation method of this material.
