Abstract
The present invention relates to a kind of fiber glass reinforced halogen-free flame retardant PBT; It is characterized in that: raw materials quality part proportioning of said fiber glass reinforced halogen-free flame retardant PBT is following: PBT is that 40-50 part, halogen-free flame retardants 10-20 part, Yodo Sol GH 28 2-8 part, nanometer level PET are 1-5 part, oxidation inhibitor 1-5 part and spun glass 20-40 part, and said halogen-free flame retardants is a melamine salt.The product of fiber glass reinforced halogen-free flame retardant PBT preparation of the present invention, low cigarette, environmental protection, and product is not easily broken, is easy to machine-shaping.
Description
Technical field
The present invention relates to a kind of fiber glass reinforced halogen-free flame retardant PBT, be mainly used in the domestic food mechanical cover.
Background technology
Polybutylene terephthalate, English name polybutylene terephthalate (being called for short PBT) can be described as the thermoplastic polyester plastic again, and PBT is that oyster white is translucent to opaque, crystalline thermoplastic polyester.Because PBT has thermotolerance, weathering resistance, resistance to chemical reagents, electrical specification is good, water-absorbent is little, gloss is good; Be widely used in electronic apparatus, auto parts, machinery, houseware etc., and the PBT product is the five big general engineering plastics of using with nominals such as PPS, PC, POM, PA.Existing P BT product is in order to reach flame retardant effect preferably; All in its raw material, add halogen flames such as bromine, chlorine; Though flame retardant effect is outstanding; Smog is big, hydrogen halide and other halogen containing organic compound of strong toxicity but burning the time can produce, and can produce dioxin during burning, and is very big to human harm.Can't reach the request for utilization of (on products such as soybean milk maker) on the food machinery.
And the employing halogen-free flame retardants, though reached low cigarette, environmental protection requirement, it will reach fire-retardant requirement and need the heavy addition halogen-free flame retardants, thereby causes its physicals low, product becomes fragile, and is difficult to machine-shaping.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, the fiber glass reinforced halogen-free flame retardant PBT that a kind of low cigarette, environmental protection is provided and is easy to process.
The objective of the invention is to realize like this:
A kind of fiber glass reinforced halogen-free flame retardant PBT, raw materials quality part proportioning of said fiber glass reinforced halogen-free flame retardant PBT is following:
PBT 40-50 part
Halogen-free flame retardants 10-20 part
Yodo Sol GH 28 2-8 part
Nanometer level PET 1-5 part
Oxidation inhibitor 1-5 part
Spun glass 20-40 part,
Said halogen-free flame retardants is a melamine salt.
The preferred melamine cyanurate of said melamine salt (MCA).
As preferred embodiment of the present invention, its raw-material proportion by weight is following:
45 parts of PBT
16 parts of melamine cyanurates
4 parts of Yodo Sol GH 28s
3 parts of nanometer level PETs
2 parts in oxidation inhibitor
30 parts in spun glass.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention, decomposition reaction takes place in the halogen-free flame retardants of employing trimeric cyanamide salt when it is heated; Have effects such as heat absorption, cooling and dilution, do not produce thick smoke, the feature of environmental protection is good; Nano level PET adds, and improves whole resistance toheat, makes flame retardant effect further improve; Reduced the consumption of the halogen-free flame retardants of trimeric cyanamide salt, its fragility is reduced; In system, add Yodo Sol GH 28 and enhance and add toughness, reduce the fragility of the finished product, make it be easy to processing, the adding of oxidation inhibitor increases product work-ing life; Add spun glass, play enhancement.
The product of fiber glass reinforced halogen-free flame retardant PBT preparation of the present invention, low cigarette, environmental protection, and product is not easily broken, is easy to machine-shaping, and flame retardant properties reaches the V0 level of U.S. UL.
