Problems solved by technology

Its main disadvantage is that its flame retardant performance is relatively low, and its compatibility with the matrix resin is poor. To make the flame retardant performance of the polymer material meet a certain requirement, the amount of its addition must often reach more than 50% of the total mass of the composite material. Have a great negative impact on the processing performance and mechanical properties of the material

Abstract

The invention discloses a polypropylene modified material and a preparation method thereof, wherein the polypropylene modified material comprises 95-105 parts of polypropylene, 30-60 parts of a metal oxide hydrate, and 10-20 parts of a polyolefin elastomer. The preparation method comprises: weighing polypropylene, a metal oxide hydrate and a polyolefin elastomer according to a certain ratio; uniformly mixing the weighed polypropylene, the weighed metal oxide hydrate and the weighed polyolefin elastomer to obtain a mixture; extruding the mixture by using an extruder to obtain an extruded material; and carrying out water washing cooling on the obtained extruded material to achieved a room temperature of 20-30 DEG C, and drying for 3-5 h at a temperature of 75-85 DEG C to obtain the polypropylene modified material. According to the present invention, the polypropylene is adopted as the matrix, a variety of the advantages of the materials are completely provided, the flame retardant agent magnesium hydroxide is added to overcome the flammability disadvantage of the polypropylene, and the polyolefin elastomer is added to toughen and modify the polypropylene, such that the material has the excellent processing performance and the excellent mechanical property compared to traditional material.

Description

technical field [0001] The invention relates to the field of polypropylene materials, in particular to a modified polypropylene material and a preparation method thereof. [0002] technical background [0003] Polypropylene (PP) is one of the five general-purpose plastics. It is widely used in various fields of industrial production and is also the fastest-growing material among general-purpose plastics. PP has many advantages such as low density, excellent mechanical properties, good electrical insulation, small dielectric constant, stress crack resistance, chemical resistance and easy processing, and is used in chemical industry, light industry, chemical fiber and other fields. With the continuous development of PP modification technology, PP materials can be compared with some engineering plastics and widely used in various fields. [0004] PP composite materials occupy an important position in industrial fields such as automobiles, electrical appliances, and instruments....
