Problems solved by technology

However, if the particle size is too small, the interaction between particles is too strong, and the inorganic particles are prone to agglomeration, resulting in uneven dispersion of particles in the polymer, which is not conducive to the improvement of toughening effect.
[0006] In addition, single-component modification can no longer meet the needs of high-performance PP preparation, and compound modification has become the main trend
At present, compound modification is mainly focused on simple blending, which cannot give full play to the comprehensive modification effect of modified fillers.
There is no literature on the modification of composite particles, and there is no literature on the shape, particle size and particle size distribution of composite modified particles

Abstract

The invention provides a polypropylene material and a preparation method thereof. The polypropylene material is prepared from the following raw materials in parts by weight: 100 to 120 parts of polypropylene, 30 to 50 parts of composite modified particle, 8 to 14 parts of ethylene bis stearamide, 0.5 to 0.9 part of chlorinated polyethylene, and 0.2 to 0.6 part of antioxidant, wherein the composite modified particle comprises 10 to 20 parts of nanometer BaCO3 whisker, 5 to 10 parts of nanometer TiO2 particle, 10 to 15 parts of nanometer Al(OH)3 particle, and 5 parts of adhesive; the nanometer TiO2 particle and the nanometer Al(OH)3 particle are adhered to the nanometer BaCO3 whisker through the adhesive. With the adoption of the preparation method, the original performances of the polypropylene material are ensured, and the toughness, strength, fire resistance and ageing resistance are improved.

Description

technical field [0001] The invention relates to a polypropylene material, in particular to a composite particle modified polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene (PP) has many advantages, and its output is second only to polyethylene among the five general-purpose plastics. As the largest PP consumer country in the world, my country's demand will continue to grow strongly in the future, and the demand prospect of PP in my country is very broad. However, PP also has disadvantages such as low-temperature brittleness and large shrinkage, which limit the development of its functions and application range. In order to improve the deficiencies in the performance of PP, different modification studies have been carried out on PP at home and abroad, and it is found that PP can be treated differently through physical modification and chemical modification to achieve the expected effect and obtain PP products with different n...
