Description

Polypropylene crystal formation regulates toughened modified mother material and preparation method thereof
technical field:
The present invention relates to a kind of polypropylene crystal formation and regulate toughened modified mother material and preparation method thereof, belong to rubber and plastic synthesis technical field.
background technology:
Polyacrylic degree of crystallinity is high, compound with regular structure, thus has excellent mechanical property.The absolute value of Mechanical Properties of PP higher than polyethylene, but still belongs to kind on the low side in a plastic material, and its tensile strength only can reach 30MPa or slightly high level.The polypropylene that isotactic index is larger has higher tensile strength, but with the raising of isotactic index, the shock strength of material declines to some extent, but no longer changes after dropping to a certain numerical value.Temperature and loading rate very large to polyacrylic Toughness.When temperature is higher than second-order transition temperature, impact fracture is ductile rupture, be brittle rupture, and impact value significantly declines lower than second-order transition temperature.Improve loading rate, the temperature that ductile rupture can be made to change to brittle rupture rises.Polypropylene has excellent flexural fatigue resistance, its goods bent 106 times and do not damage at normal temperatures.But under room temperature and low temperature, because the molecular structure regularity of itself is high, so resistance to impact shock is poor.
summary of the invention:
The object of the invention is to provide a kind of polypropylene crystal formation to regulate toughened modified mother material and preparation method thereof for above-mentioned Problems existing, the masterbatch of preparation can significantly improve polyacrylic low temperature brittleness and stress cracking.
Above-mentioned object is achieved through the following technical solutions:

Described polypropylene crystal formation regulates toughened modified mother material, described compatibilization and toughening properties-correcting agent comprises oxidation, catalyzer, rosin Amine D, aniline, epoxy resin, and the mass content of each component is: oxidation 50-60%, catalyzer 0.6-3%, rosin Amine D 10-15%, aniline 10-20%, epoxy resin 15-40%.
Described polypropylene crystal formation regulates toughened modified mother material, and described catalyzer is ZnCl 2or AlCl 3.
Above-mentioned polypropylene crystal formation regulates the preparation method of toughened modified mother material, and the method comprises the steps:
(1) compatibilization and toughening properties-correcting agent is prepared: oxidation is added catalyzer and obtain poly fatty acid ester; Be hydrolyzed by obtained poly fatty acid ester, wash and obtain poly lipid acid, then in proportion, mixed by obtained poly lipid acid with rosin Amine D, aniline, under 200-220 DEG C of condition, reaction 2-4h i.e. obtained compatibilization and toughening properties-correcting agent;
(2) by weight by the compatibilization and toughening properties-correcting agent that polypropylene, polyethylene and step (1) are obtained, adopt parallel dual-screw height mixing facilities to carry out mixing granulation, obtain polypropylene crystal formation and regulate toughened modified mother material.
Beneficial effect:
Polypropylene crystal formation prepared by the present invention regulates and toughened modified mother material can not only regulate and control polypropylene spherulite size and distribution in molding process, and can significantly improve polyacrylic low temperature brittleness and stress cracking.
The key technical indexes:
Project Testing method Unit Index
1, density GB/T1033-86 Kg/m3 0.92
2, melt index GB/T3682-1992（190℃，2.16kg） g/10min 2－4
3, tensile strength GB/T1040-92 MPa ＞10
4, shock strength GB/T1043-93（-20℃） kJ/m2 ＞40
This masterbatch and polypropylene compatible good, alternative POE thermoplastic elastomer, recommendation amount is 6-8phr, on Co-polypropylene (water-feeding pipes level) basis, when addition is 6phr, normal temperature shock strength improves 18%, and-20 DEG C of low temperature impact strengths improve 10%.It can not only regulate and control polypropylene spherulite size and distribution in molding process, and significantly improves low temperature brittleness and the stress cracking performance of PPR pipe, is also suitable for the injection moulding of large size, thin walled goods, and the component that can be used for conditioner are produced.
