In order to realize above-mentioned purpose, the present invention by the following technical solutions:
The PP fire-retardant master granule of a kind of potassium titanate crystal whisker enhancing modified, is prepared from by the raw material of following weight portion:
Described potassium titanate crystal whisker is K2Ti6O13Or K2Ti8O17, and potassium titanate crystal whisker is through silane coupler pretreatment, titanium
Acid potassium whisker preprocess method is: for 9:1, dehydrated alcohol is prepared ethanol solution by volume with distilled water, by silane coupler
KH-570 instills in ethanol solution and hydrolyzes 30 minutes, obtains the mixed solution that volume fraction is 1% of Silane coupling reagent KH-570,
Then adding potassium titanate crystal whisker in mixed solution, the quality of Silane coupling reagent KH-570 is the 5% of potassium titanate crystal whisker quality, adds
The regulation pH value such as dilute hydrochloric acid or acetic acid, to 5-6, stirs 2 hours at 40 DEG C, is produced by the solid of reacted gained with distilled water
Thing washing, to neutral, dried, is obtained modified modified potassium titanate crystal whisker；The fibre diameter of modified potassium titanate crystal whisker
For 0.2-1.5 micron.
Described halogen-free flame retardants is any one in melamine ammonium pyrophosphate, expansible graphite and aluminium hydroxide,
Or any two kinds, or the combination of three.
Described halogen-free flame retardants is melamine ammonium pyrophosphate, expansible graphite and the combination of aluminium hydroxide three, three
The mass ratio of poly cyanamid ammonium pyrophosphate, expansible graphite and aluminium hydroxide is 5:2:3.
Described synergistic flame retardant is bismuth oxide.
Described plasticizer is polyethylene terephthalate.
Described Hinered phenols antioxidant is 2,6-di-t-butyl-PAP.
The preparation method of the PP fire-retardant master granule of a kind of potassium titanate crystal whisker enhancing modified, comprises the steps:
By COPP, maleic anhydride inoculated polypropylene, potassium titanate crystal whisker, halogen-free flame retardants, synergistic flame retardant, plasticising
Agent and Hinered phenols antioxidant addition double screw extruder carry out extruding pelletization, controls twin-screw extruder barrel one district temperature
Being 170 ± 5 DEG C, two district's temperature are 180 ± 5 DEG C, and three district's temperature are 190 ± 5 DEG C, and four district's temperature are 200 ± 5 DEG C, five district's temperature
Being 205 ± 5 DEG C, six district's temperature are 210 ± 5 DEG C, and seven district's temperature are 205 ± 5 DEG C, and eight district's temperature are 200 ± 5 DEG C, nine district's temperature
Being 190 ± 5 DEG C, screw speed is 350rpm, obtains the PP fire-retardant master granule of potassium titanate crystal whisker enhancing modified.
The present invention compared with prior art, has the following advantages and effect:
1) present invention uses the PP fire-retardant master granule of potassium titanate crystal whisker enhancing modified to have the advantage that 1) potassium titanate crystal whisker chi
Very little trickle, its fibre diameter (0.2～1.5 μm) contrast carbon fiber, the fibre diameter (7～13 μm) of glass fibre so that metatitanic acid
Potassium whisker has excellent micro-enhancing and filling capacity, the forming operation as can carrying out with packless resin；2) titanium
Acid the hardness ratio carbon fiber of potassium whisker, glass fibre will be little, in forming process, the abrasion to process equipment and mould is little；3)
After potassium titanate crystal whisker strengthens and fills, PP fire-retardant master granule linear expansion coefficient and molding shrinkage are greatly reduced, and make profiled part be subject to
Heat and enough dimensional stability can be kept when catching a cold；4) fine after the PP fire-retardant master granule granulation after potassium titanate crystal whisker enhancing modified
Compared with the PP flame-proof composite material of the enhancing modified such as conservation rate and the glass fibre of dimension length, there is raising largely, because of
And it can repeatedly be processed, show good circular regeneration.As can be seen here, the present invention uses potassium titanate crystal whisker enhancing modified
PP fire-retardant master granule, overcomes when glass fibre, carbon fiber, Plant fiber and basalt fibre strengthen PP and there is fluidity of molten
Difference, big to screw rod and die wear, article surface is the brightest and the cleanest, the shortcoming of regeneration cycle usability difference.
2) potassium titanate crystal whisker has the high infrared reflection rate not available for general fibre and low heat conductivity so that potassium titanate is brilliant
The PP fire-retardant master granule of palpus enhancing modified also has broad application prospects in insulating refractory field.
