Description
Technical field
The present invention relates to technical field of composite materials, concrete a kind of PP composite and preparation method thereof.
Background technology
Long glass fibres strengthens pellet and refers to the pellet of one-way fiber arrangement, and its fibre length is equal with pellet length,
Generally higher than 5mm.At home, the research of roving glass fiber is still at an early stage, and roving glass fiber is generally used for improving macromolecular material
Mechanical property.Acrylic resin (PP) is a kind of broad-spectrum general-purpose plastics, propylene monomer polymerization prepare, acrylic resin
Advantage be that density is low, low price, and there is excellent chemical resistance, preferable mechanical performance, prominent folding
Folded property and good moulding processability.As typical crystalline materials, its fusing point is near 165 DEG C.
Long glass fiber reinforced PP material is to have high intensity, high impact resistance, and dimensionally stable is good, is a kind of " Qiang Erren "
Material, PP is adding after glass fiber reinforcement, is being greatly improved its mechanical performance, heat resistant type and dimensional stability.Should in reality
To mould Dai Gang and enhancement engineering plastics can be replaced in, meet the field uses such as small arms packing crates, automotive field, household electrical appliances and want
Ask.The existing usual fire resistance of PP polymer is poor, and safety is low, limits its application in many fields；Such as exist
Application in luminaire/automobile construction, PP polymer must is fulfilled for the harshest fire-protection standard, can only be by adding for this
Fire retardant strengthens the fire resistance of product.Meanwhile, during with long glass fiber reinforced PP, due to " wick effect " of roving glass fiber, especially
Promote the burning of PP resin.Existing PP, roving glass fiber product, in order to reach preferable flame retardant effect, all add in its raw material
Add the halogen flame such as bromine, chlorine, although flame retardant effect is outstanding, but can produce during burning that smog is big, the hydrogen halides of strong toxicity and
Other halogen containing organic compound, and two English can be produced during burning, very big to harm.It is known that halogenated flame retardant is fire-retardant
Material can produce smog the most poisonous, mordant when burning, environment, mould is had pollution, corrosiveness, sends out in many
Reach country to have been disabled；Although most of halogen-free flame retardants effects are pretty good, but owing to cost is the highest so that it is be difficult in state
Inside promote the use of.Additionally, " wick effect " unsubstantial remission effect that these fire retardants are to roving glass fiber, and high temperature is weak to
It is subject to, at high temperature easily decomposes and lost efficacy, it is impossible to the problem fundamentally solving roving glass fiber PP composite fire protecting performance difference.
Summary of the invention
In view of this, the present invention discloses a kind of halogen-free, roving glass fiber PP composite of excellent flame retardancy.
The purpose of the present invention is achieved through the following technical solutions:
A kind of PP composite, its raw material includes by weight:

The described a length of 8-15mm of alkali-free continuous glass-fiber, a diameter of 11-20 μm；It is right that its raw material of described fire retardant includes by weight
Nitrobenzyl alcohol 2-5 part, Firebrake ZB 3-7 part, polyacrylic acid potassium 0.02-0.06 part.
Described PP can be selected for prior art and realizes.Described compatilizer, antioxidant all can be selected for any one applicable PP resin
Prior art realizes.The present invention is specifically designed a kind of fire retardant, and it comprises appropriate to nitrobenzyl alcohol, Firebrake ZB, polyacrylic acid
Potassium.To nitrobenzyl alcohol, have another name called nitrobenzyl alcohol malonic acid monoester, 4-nitrobenzyl alcohol, p nitrobenzyl alcohol, white or faint yellow
Crystal.Fusing point 93 ~ 96 DEG C, 185 DEG C/1600Pa(12mmHg of boiling point).It is soluble in ethanol, ether, is slightly soluble in cold water, at 25 DEG C
Dissolubility 1% in water, dissolubility 10% in 100 DEG C of water, it is usually used in chemical field.Firebrake ZB is the halogen-free flame-retardant of a kind of environment-friendly type
Agent, the feature such as nontoxic, low aqueous solubility, high thermal stability, granularity are little, proportion is little, good dispersion, as a kind of efficient flame-retarding agent quilt
It is widely used in the fields such as plastics, rubber, coating.Polyacrylic acid potassium is commercially available prod.Inventor finds under study for action, to long glass
Fine PP composite adds polyacrylic acid potassium, to nitrobenzyl alcohol, Firebrake ZB time can be effectively improved the fire resistance of product,
Under high temperature, composite does not burns.Especially, above-mentioned fire retardant can effectively suppress composite drippage when burning.
Described alkali-free continuous glass-fiber preferred length is 8-15mm, a diameter of 11-20 μm.The fire retardant of the present invention long glass to above-mentioned specification
Fine effect is the most obvious.
Further, described compatilizer be ABS compatilizer, described antioxidant be antioxidant 1010 or irgasfos 168.

Agent includes the sodium sulfate of the part of 2-3 by weight, 0.1-0.3 part disodium hydrogen phosphate and the hydrochloric acid of 2-3 part 3wt% concentration.
Roving glass fiber PP composite is when injection, due to the mobility of low temperature, PP and roving glass fiber, the density variation of mould,
Roving glass fiber easily separates with PP, causes the floating fine roving glass fiber of product surface of molding, while affecting product appearance, due to product table
The roving glass fiber in face is assembled and the most crisp, frangible, and interiors of products roving glass fiber concentration is low and easy stress deformation.Therefore the present invention is special
Add thermoplastic stabilizer, maintain roving glass fiber, the stability of PP mixed system when roving glass fiber PP composite of the present invention is molded, anti-
Only under molten condition, roving glass fiber is layered with PP, it is ensured that the smooth in appearance of injecting products and possess good mechanical property.More than imitate
Fruit has sodium sulfate, disodium hydrogen phosphate and hydrochloric acid synergistic to produce.
Present invention simultaneously provides a kind of method preparing described PP composite, comprise the steps:
A. fire retardant is prepared: heating in water bath will be used to 80 degrees Celsius nitrobenzyl alcohol, Firebrake ZB, polyacrylic acid potassium, and be incubated
120min；
B. the preparation of thermoplastic stabilizer: by described sodium sulfate, disodium hydrogen phosphate and mixed in hydrochloric acid, is heated to 50 DEG C and keeps
20min；
C. press setting weight part and PP, fire retardant, compatilizer, antioxidant, thermoplastic stabilizer are added super mixer mix homogeneously
Post-heating is cooled to 35～40 DEG C after 100～110 DEG C, is subsequently adding the alkali-free roving glass fiber of setting weight part, through mixed
Refining, forming processes prepare long glass fiber reinforced PP composite.
Above fire retardant, the preparation method of thermoplastic stabilizer, be conducive to improving compatilizer, the sending out of thermoplastic stabilizer effectiveness
Wave.The unspecified technical characteristic of the present invention, all can be selected for prior art and realizes.
