The enterprise of bright electric appliance is more and more.
Mainstay material used in existing illuminating industry is makrolon material, which has splendid mechanical property, optics
Performance, insulation performance, flame retardant property and dimensional stability, but higher cost.And polypropylene material at low cost is with splendid
Machinability, chemical-resistant and good mechanical property, insulation performance, but because of its flame retardant property and poor dimensional stability,
Limit its application in electric lighting industry.
Patent CN201610682477.1 discloses a kind of high obscurity PP composite material comprising polypropylene gathers
Olefin type elastomer, titanium dioxide, mica powder, antioxidant, nucleating agent and lubricant are added in polypropylene material and press certain mass
Than mixed titanium dioxide and mica powder, the light-proofness of polypropylene material is improved, by increasing glass fibre, improves shading poly- third
The mechanical property of alkene material.But do not consider electric lighting temperature is excessively high, components aging in the case where be easy to happen fire, cause
Security risk.
Summary of the invention
For solve the problems, such as the deficiencies in the prior art mentioned above and, the present invention provides a kind of fire-retardant shading low receipts
Polycondensation acrylic composite, component according to the weight ratio include:
Further, the polypropylene is made of homopolypropylene and copolymer polypropylene, wherein the homopolypropylene
For crystallinity 60% or more, melt flow rate (MFR) is not less than 20g/10min；The copolymer polypropylene melt flow rate (MFR) is not less than
30g/10min。
Further, the wollastonite and calcium sulfate crystal whiskers average diameter 6-8um, average length 150-200um are passed through in advance
Cross silane coupling agent processing.
Further, alkali-free chopped glass fiber of the glass fibre for Mount Taishan glass fibre company, average diameter 11um, in advance
First pass through silane coupling agent processing.
Further, the compatilizer is maleic anhydride inoculated polypropylene, grafting rate 0.8%.
Further, the titanium dioxide is rutile-type, first passes through silane coupling agent processing in advance.
Further, the fire retarding synergist is antimony oxide, and the fire retardant is decabromodiphenylethane and eight bromine sulphur
At least one of ether.
Further, the antioxidant is at least one of phosphite ester antioxidant and Hinered phenols antioxidant, institute
Stating lubricant is at least one of vinyl bis-stearamides and silicone master batch.
The present invention also provides a kind of fire-retardant shading low-shrink polypropylene composite material and preparation method thereofs as described above, including with
Lower step:
The material except sulfuric acid calcium pyroborate, wollastonite and glass fibre is weighed according to corresponding component and weight proportion,
In high-speed mixer and mixing 15min, above-mentioned raw material are uniformly mixed, mixed blend is squeezed out by double screw extruder
It is granulated；Wherein calcium sulfate crystal whiskers, wollastonite are put into according to corresponding weight proportion from the 6th area's side feed material, and glass fibre is according to phase
The weight proportion answered is put into from the 8th area's side feed material.
Further, each area's temperature of extruder be followed successively by from feeding section to head temperature 160 DEG C, 170 DEG C, 180 DEG C,
190 DEG C, 200 DEG C, 205 DEG C, 200 DEG C, 205 DEG C, 195 DEG C, 185 DEG C, extrusion screw rod draw ratio are 44, and extrusion screw rod revolving speed is
400 revs/min.
It solves the problems, such as shading and the lower shrinkage of polypropylene material in the prior art, does not consider the fire-retardant need of illuminating product
It asks.And addition calcium sulfate crystal whiskers and glass fibre increase the shearing between screw rod and material in process, and it will certainly
Fire retardant is caused to decompose, fire retardant is added by main feeding in the present invention, enhances the dispersion of fire retardant.Sulphur is being added in bilateral feeding
Sour calcium pyroborate and glass fibre can be reduced the shearing of whisker and glass, on the one hand fire retardant avoided to decompose, on the other hand, can be with
The length of the effective length for keeping calcium sulfate crystal whiskers and glass fibre, calcium sulfate crystal whiskers and glass fibre is longer, in polymer
The bridge joint transmitting energy played the role of in matrix is bigger, and then improves the performance of material entirety.
Fire retardant and fire retarding synergist have been fire retardations, pass through the noninflammability gas of the layer of charcoal and generation that are formed when burning
Body separates heat, oxygen and flame.V2 grades of fire-retardant and 750 DEG C of glowing filaments performances are reached by both additives.Shading
It is titanium dioxide and the generation of fire retardant synergistic effect as a result, the calcium sulfate crystal whiskers and glass that add simultaneously also function to fine shading effect
Fruit.Lower shrinkage is mainly that the calcium sulfate crystal whiskers added and glass work.Polypropylene material itself is because crystallization can be shunk, generally
Between 1.8-2.2%, the filler of addition can slow down the contraction of material, and shape, partial size, draw ratio and the thickness of filler all can be right
The contraction of PP material has an impact.
The modified polypropylene material involved in the present invention arrived can reach shading, lower shrinkage, V2 grades of fire-retardant, 750 DEG C of glowing filaments
Flammability index and 125 DEG C of hot-bulb pressures, while maintaining certain toughness.Alternative PC material is applied to ceiling rear lamp cover, lamp housing
On equal components, product cost is reduced, the application field of anti-flaming polypropylene material is widened.
