32~68, metering needed for side feed material is known as solid screw.
Here is the formula contrast table (unit %) of different embodiments from different comparative examples:
The performance test results table of different embodiments and different comparative examples below:
In upper table, comparative example 1 is the reinforced ABS containing 15% glass of current production fan blade, and physical mechanical property is higher,
But material only has very low HB grade, under flame, fan blade is burnt, and product does not extinguish, and fire safety performance is very poor.
In comparative example 2 and comparative example 3, the fire retardant of fiberglass reinforced fire retardant ABS is currently used brominated triazine and bromine
Change epoxies, since these two types of fire-retardant middle ignition-proof element bromine contents are few, to reach UL-94-V0 grades of same levels, the addition needed
Amount is big, so that raw material ABS resin relative amount declines in fiberglass reinforced fire retardant ABS system, product is laid particular stress on more；Meanwhile this
A large amount of additions of a little powder shaped fire retardants also weaken the interfacial bonding effect of enhancing system, lead to tensile strength of material and punching
The deterioration of the mechanical performances such as toughness is hit, so that pulling force, torsion and fall-down test, the heat pilot projects such as static do not conform in fan blade test
, there is drawing crack phenomenon in lattice, when product stripping.
Embodiment 1-4 using the fire retardant based on decabromodiphenylethane, decabromodiphenylethane bromine content be up to 82% with
On, therefore only need to add that identical flame retardant effect can be reached on a small quantity, but decabromodiphenylethane is filled-type fire retardant,
Than enhancing the more of system melting means decline after brominated triazine addition, it is unfavorable for Injection filling, therefore, the present invention, which uses, changes mobility
Being apt to apparent tetrabromobisphenol A is that auxiliary flame retardant improves the flowing of enhancing system under the premise of not reducing flame retardant property
Property.After tested, the fiberglass reinforced fire retardant ABS 5VA material being prepared using this programme, tensile strength, bending strength and impact
Although toughness etc. is than the routine under identical glass fiber content, flame-retardant system is not low, it is higher than with brominated triazine and brominated
The fire-retardant fiberglass reinforced system of oxygen, and melting means is higher than common enhancing system, can be molded thin-walled fan blade, and injection molding fan blade process is filled
