Related content in the technique scheme is explained as follows:
1, in the such scheme, in order further to improve PA6 and PP two-phase interface cohesive force, described sulfonated polystyrene zinc compatilizer is the high polymer product, and the ionic group in its polymkeric substance is in 15%mol.
2, in the such scheme, antioxidant 1010 and oxidation inhibitor 168 are trade(brand)name and trade names.
3, in the such scheme, during described (2) step main ingredient mixes, adopt agitator under the high-speed condition more than the 1000 commentaries on classics/per minutes, to mix stirring, better effects if like this.
4, in the such scheme, described aftertreatment comprises cooling, air-dry, pelletizing, sieves, crosses magnetic, drying, flow package.
Gordian technique of the present invention and principle are as follows:
The present invention adopts novel high polymer compatilizer, has obtained the PA6/PP alloy material of better over-all properties.High polymer is meant the polymkeric substance that contains a small amount of (being no more than 15%mol) ionic group, is when polar polymer and non-polar polymer blend, can play good compatibilization.Its principle be nylon 6 with amide group in nitrogen-atoms on have lone-pair electron, can form coordinate bond with the zinc atom in this ionomer, thereby produce the co-crosslinking effect.Studies show that this ionomer has not only improved the dispersiveness of polyolefin elastomer in the nylon-6 matrix body significantly, reduces the disperse phase particle diameter; Simultaneously, this ionomer can form a kind of flocbed between nylon-6 matrix body and elastomerics, produces very intensive interaction in the flocculation zone, thereby has improved the interface compatibility between nylon 6 and the elastomerics effectively.
Adopt polyphosphoric acid amine and trimeric cyanamide as main flame retardant.The fire retardant mechanism of polyphosphoric acid amine is to generate the strong dewatering agent of polyphosphoric acid after its thermal dehydration, impel the polymer surfaces dehydration to generate carbide, the oxide compound of the non-volatile phosphorus of Sheng Chenging and polyphosphoric acid cover substrate surface in addition, thereby secluding air reaches fire-retardant purpose.
Polyphosphoric acid amine contains the nitrogen element simultaneously, and decomposes is emitted CO 2, N 2, NH 3Deng gas, these gases are nonflammable, blocked the supply of oxygen, realized fire-resistant synergistic and synergistic effect.
The heat of sublimation of trimeric cyanamide is 121.3 ± 4.1KJ/mol, when polymkeric substance is lighted, and trimeric cyanamide literization and absorbing heat, the combustion heat of volatile matter is very little simultaneously, for-1965KJ/mol, littler 2～3 times than the combustion heat of general degraded product, reduced the transmission of heat.When burning, every mole trimeric cyanamide produces 3 moles water, CO 2, N 2, play a part to expire heat absorption and dilution, and gas is emitted simultaneously in a large number, breaks up the polymer cracking volatile matter, reduces their residence time in the combustion zone, and takes away a large amount of heat.The volatile matter of trimeric cyanamide is combinate form Cheng Baiyan again, for polymer surfaces provides " trisome ", removes the momentum that free radical collides mutually, has allowed the recombination of free radical, has stoped the transmission of radiating capacity, also absorbs energy as " hot trap ".Polycondensation takes place in the trimeric cyanamide part that do not distil fully, emits ammonia, forms polycyclotrimerization cyanamide derivative, impels PA6 to become carbon.In a word, trimeric cyanamide is in the lighting of polymkeric substance, flame transmission, and a cohesion cracking and fire-retardant the grade are played certain interception in each process.
Because of there is defective in these two kinds of main flame retardants, promptly high temperature or big medium-term and long-term use of environment of temperature, " frosting " phenomenon can appear, selected for use aminosilane to come main flame retardant is handled so originally return, main flame retardant dispersed, the bad problem of consistency in system have been solved, well play the effect of coupling agent, successfully solved product of the present invention " frosting " phenomenon under hot and humid condition.
Because the technique scheme utilization, the present invention compared with prior art has following advantage and effect:

2) flame-retardant system efficiently
The present invention adopts composite halogen-free flame retardants system---the trimeric cyanamide and the polyphosphoric acid amine cooperative flame retardant of design voluntarily, with aminosilane fire retardant is carried out surface treatment simultaneously, adding the oxidation sb system with traditional decabromodiphenyl oxide compares, it is little to have addition, the amount of being fuming is little, and " frosting " phenomenon can not appear in product, and outward appearance is good, little to environmental damage, to characteristics such as other performance impacts of product are little.Meeting in the world the non-halogen requirement of flame retardant plastics, is the upgraded product of environment-friendly type flame-retardant plastic.
3) take the lead in developing PA6/PP alloy with environment-friendly high fire-retardant performance
