Polypropylene composite material as well as preparation method and application thereof

Abstract

The invention discloses a polypropylene composite material as well as a preparation method and an application thereof, and relates to the field of modified plastics. The invention provides the polypropylene composite material. The polypropylene composite material comprises the following components in parts by weight: 70-90 parts of polypropylene resin, 2.3-3 parts of a flame-retardant composition and 6-12 parts of an insect-repelling composition, wherein the flame-retardant composition is prepared from the following components: aluminum hypophosphite, melamine cyanurate and mercuric chloride; the insect repelling composition contains furocoumarin, and the mass percent of the furocoumarin in the insect repelling composition is 5-60%. The insect-repelling composition further comprises at least one of fipronil and bifenthrin. The invention provides a flame-retardant PP material with termite repelling and killing functions.

Description

technical field [0001] The invention relates to the field of modified plastics, in particular to a polypropylene composite material and its preparation method and application. Background technique [0002] As one of the five general-purpose plastics, PP (polypropylene) is widely used in electrical contact industries such as power strips, wall switches, and household appliances due to its light weight, corrosion resistance, and low price. Sockets, wall switches, and household appliances are in contact with the power supply, so the materials used must have good flame retardant properties. Secondly, with the advent of summer, the reproduction of termites is accelerating, especially in the southern region, where sockets, switches, and household appliances are easily eaten by termites. After the shell is eaten, the internal metal structure is exposed, which is likely to cause electric shock and safety accidents. The repellency to termites is a very practical function in daily li...

AI Technical Summary

Problems solved by technology

In areas where wall switches, household appliance connectors, etc. are in contact with power lines, the plastic parts are used as the protective shell of the power line, which not only has flame retardant requirements, but also transparency requirements, so that consumers and maintenance personnel can monitor the internal power lines. state, convenient for maintenance and repair, and the addition of flame retardants will seriously reduce the transparency of the material, and too much addition of flame retardants will also affect the toughness and impact strength of the material

Although some domestic flame-retardant PP materials have good flame-retardant properties, they have low impact strength and poor transparency.

Flame-retardant PP materials used in industries such as sockets, wall switches, and household appliances on the market generally have problems such as low transparency and no termite repellency.
