Problems solved by technology

[0004] However, the existing flame retardant masterbatches are mainly octabromine products, which are severely precipitated during use, have a large specific gravity, and have poor processing stability. Moreover, the recycling process is not environmentally friendly and has a great impact on the environment.

Abstract

The invention discloses a PP (Polypropylene) high efficiency concentrated flame retardant masterbatch. The PP high efficiency concentrated flame retardant masterbatch is prepared from the following components in percentage by mass: 20 to 40 percent of PP particles, 0.5 to 1 percent of a coupling agent, 15 to 30 percent of hypophosphite, 10 to 20 percent of bromine and 15 to 25 percent of ultrafine talcum powder. By adopting the mode, the PP high efficiency concentrated flame retardant masterbatch disclosed by the invention has the characteristics of high efficiency, flame-retardant property, environment friendliness, low cost and the like; in addition, the PP high efficiency concentrated flame retardant masterbatch has the advantages of simplicity in use, high processing stability and facilitation for secondary recycling; besides, the produced product has high coloring rate, no separation-out and light specific gravity; all the components completely meet the requirements of EU ROHS standards and reach the fireproofing requirements of UL94-V2.

Description

technical field [0001] The invention relates to the field of polypropylene materials, in particular to a PP high-efficiency concentrated flame-retardant masterbatch. Background technique [0002] With the advancement of science and technology and the improvement of living standards, polymer materials, especially synthetic polymers such as plastics and rubber, are becoming more and more important in people's lives, and their applications are showing a trend of expanding year by year. However, most organic polymer materials have different degrees of flammability in the air. In order to realize their applications in many industries such as military, aerospace, transportation, electric power and civil use, their flame retardant modification has become a new topic. At present, the ideal method of flame retardant modification of plastics is often to improve the fire resistance of plastics by adding products such as flame retardants or flame retardant masterbatches. [0003] Flame...
