Embodiment 1

[0017] According to the proportion: polypropylene 40%-50%, ricinoleic acid 10%-15%, carbon black 10%-15%, expanded graphite 20%-30% and red phosphorus 10%-15%, take out each component, the total The weight is 100kg, spare.

[0018] for:

[0019] 1. Mix polypropylene and red phosphorus according to the ratio of 4:1. After fully mixing, use a flat twin-screw extruder to extrude and granulate at 180°C and a pressure of 5 MPa. Base material A;

[0020] 2. Add ricinoleic acid to the base material A according to the ratio of 5:1, stir well, so that the base material A is evenly covered with ricinoleic acid;

[0021] 3. Add carbon black and expanded graphite to base material A covered with ricinoleic acid and stir fully;

[0022] Ricinoleic acid is used in the preparation of surfactants, plasticizers, lubricating oil additives, and also in the preparation of sebacic acid, heptanoic acid, etc. Therefore, the effect of ricinoleic acid can make carbon black and expanded graphite bet...

Embodiment 3

[0037] According to the proportion: polypropylene 40%-50%, ricinoleic acid 10%-15%, carbon black 10%-15%, expanded graphite 20%-30% and red phosphorus 10%-15%, take out each component, the total The weight is 100kg, spare.

[0038] for:

[0039] 1. Mix polypropylene and red phosphorus according to the ratio of 4:1. After fully mixing, use a flat twin-screw extruder to extrude and granulate at 195°C and a pressure of 8 MPa. Base material A;

[0040] 2. Add ricinoleic acid to the base material A according to the ratio of 5:1, stir well, so that the base material A is evenly covered with ricinoleic acid;

[0041] 3. Add carbon black and expanded graphite to base material A covered with ricinoleic acid and stir fully;

[0042] Ricinoleic acid is used in the preparation of surfactants, plasticizers, lubricating oil additives, and also in the preparation of sebacic acid, heptanoic acid, etc. Therefore, the effect of ricinoleic acid can make carbon black and expanded graphite bet...

Abstract

The invention relates to intumescent flame-retardant plastic, which comprises the following components by mass: 40%-50% of polypropylene, 10%-15% of ricinoleic acid, 10%-15% of carbon black, 20%-30% of expanded graphite and 10%-15% of red phosphorus. According to the invention, the product is non-combustible, prevents combustion, and can treat a combustion condition oxygen, wherein the intumescentflame-retardant plastic rapidly expands when meeting fire to encapsulate a flame point in the intumescent flame-retardant plastic and exhaust surrounding air, so that the existence of the surroundingair is extinguished, and fire disasters are prevented from happening physically.

Description

technical field [0001] The invention relates to a flame-retardant plastic, in particular to an intumescent flame-retardant plastic. Background technique [0002] The United States is one of the countries with relatively sound flame retardant technical regulations in the world. It has made flame retardant regulations on public entertainment and all aspects of daily life. For example, the United States has made regulations on the flame retardant performance of children's pajamas and general clothing. . Canada, Australia, and the United Kingdom have also formulated relevant technical regulations, such as requirements for the flame retardant performance of children's evening wear, and the United Kingdom also has regulations on the flame retardant performance of adult evening wear, and stipulates test methods. However, our country is still blank in this regard, and has only formulated mandatory national standards for flame-retardant clothing worn by people engaged in special ind...
