Embodiment
For the ease of the understanding of those skilled in the art, present invention work is further retouched in detail below in conjunction with specific embodiment
State.
In following each embodiments, compatilizer refers to by means of intermolecular bonding force, promotes incompatible two kinds poly-
Compound is incorporated in one, and then the auxiliary agent for the blend stablized, and applies in modifying plastics, can obtain performance well altogether
Mixcibility material, the compatibility of composite and the dispersiveness of filler are greatly improved, so as to improve composite machinery intensity.Its
In, maleic anhydride grafting compatilizer can improve inorganic filler and organic resin compatibility, improve stretching, the impact strength of product,
High filling is realized, reduces resin demand, improves rheological performance, improves surface smoothness.
Glass fibre can improve the intensity and rigidity of plastics, improve heat resistance and heat distortion temperature, improve dimensionally stable
Property, shrinkage factor is reduced, reduces buckling deformation, reduces creep, to fire resistance because candle wick effect, flame-retardant system can be disturbed, shadow
Flame retardant effect is rung, reduces the glossiness on surface, increases hygroscopicity.Wherein, chopped strand has excellent dry state mobility, to even
Continuous feeding is highly beneficial, glass fibre distributing very evenly in product.
Toughener is with the analog assistant for reducing composite fragility and raising composite shock resistance.In PA
After ASA blending solidifications, the elongation of its bonded part is low, and fragility is larger, is easy to produce when external force is born in bonding site
Crackle, and extend rapidly, cause glue-line to ftracture, not endurance, it is impossible to be used as structural bond.Therefore, it is necessary to try to reduce
Fragility, increase toughness, improve bearing strength.Addition toughener is then a selection well.
Nucleator is by changing the crystallization behavior of resin, so as to accelerating crystalline rate, increasing crystal density and promoting crystal grain
Size miniaturization, reach shorten molding cycle, improve the product transparency, lustrous surface, tensile strength, rigidity, heat distortion temperature,
The physical and mechanical properties such as impact resistance, creep resistance.
Lubricant is divided into in-lubricant and external lubricant, and the effect of external lubricant mainly improves polymer melt and equipment
Hot metal surface andfrictional conditions, plastic is easily stripped, it is poor with the compatibility of polymer, easily past from melt
External migration, one layer of very thin barrier film can be formed between melt and mould in forming process, plastics is not stick to die surface；
In-lubricant has good compatibility with polymer, the work of its cohesive force between polymeric inner plays and reduces polymer molecule
With so as to improve the mobility of the interior frictional heat and melt of plastic melt.In-lubricant and the intermolecular knot of polymer long-chain
Conjunction is not strong, and they are there may be the effect similar to rolling bearing, therefore its own can be arranged on melt flows direction,
So as to slide over each other so that internal friction reduces, and here it is the mechanism of interior lubrication.Wherein, OPE is excellent new
Type polar waxes, because OPE strand carries a certain amount of carbonyl and hydroxyl, so with filler, pigment, polarity tree
The intermiscibility of fat just significantly improves；Polarity ethylene bis-fatty acid amides TAF not only has good external lubrication effect, and
And with the effect of good internal lubrication so that molten mobility and release property every plastics is improved in plastics processing, so as to
The yield of plastic processing is improved, reduces energy consumption, and product is obtained high surface smooth finish, flatness；Season penta
Tetrol stearate PETS has good heat endurance and low volatility, the good demoulding and mobile performance at high temperature, right
The plastics of partially crystallizable have fabulous nucleation, available for opaque products.The heat endurance that PETS is protruded, makes it can be used for this
The process of class system, without worrying to degrade, and it can significantly improve transparency and surface smoothness.
Antioxidant can delay or suppress the progress of polymer oxidizing process, make so as to prevent the aging of polymer and extend it
Use the life-span.Preferable antioxidant should possess following condition：There should be high oxidation resistance；It is good with the compatibility of resin, do not separate out；
Processing characteristics is good, non-volatile under the processing temperature of high polymer, do not decompose；Resistance to extractable is good, in not soluble in water and oily；Itself
Color is preferably colourless or light, not pollute product；It is nontoxic or less toxic；It is cheap.And in fact, any antioxidant
Above-mentioned condition can not be all fully met, therefore, is typically used cooperatively using a variety of antioxidant, to produce cooperative effect.
