Problems solved by technology

It is a mature and well-known technology to use the above-mentioned flame retardants and antimony oxides for polyolefin flame retardancy. Decabromodiphenyl ether, decabromodiphenylethane and other flame-retardant polyolefins will be affected due to large additions. Mechanical properties of materials, TBC and BT93 have average flame retardant efficiency and are expensive, OBE and other flame retardants have high flame retardant efficiency but are easy to precipitate from the surface of flame retardant polyolefin
In recent years, octabromosulfide is the most...

Embodiment 1

[0049] Weigh 20KG of aluminum 2-carboxyethylphenylphosphinate, 65KG of melamine hydrobromide, 3,3,6,6,9,9-hexamethylene-1,2,4,5-tetraoxane Put 15KG of nonane into the mixer and mix thoroughly to obtain a high-efficiency precipitation-resistant flame retardant composition. Add a small amount of this composition to homopolypropylene, and add an appropriate amount of processing aids, antioxidants and light stabilizers. The resulting flame-retardant polypropylene has a flame-retardant grade of UL94 V-0 and can be tested in natural air at 80°C. After 1000 hours, no flame retardant precipitated on the surface.

Embodiment 2-26

[0051] Weigh it according to the ratio of each substance shown in Table 1, and then put it into a mixer and mix thoroughly to obtain a high-efficiency precipitation-resistant flame retardant composition. This composition was added into homopolypropylene according to a certain proportion and appropriate amount of processing aids, antioxidants and light stabilizers, and then its flame retardancy and precipitation resistance were tested. The results are shown in Table 1.

Abstract

The invention discloses an efficient precipitation resistant flame retardant composition and a preparation method thereof, in particular to the highly efficient precipitation resistant flame retardant composition suitable for flame retardant polyolefin materials and the preparation method thereof. The highly efficient precipitation resistant flame retardant composition comprises the following components by weight percent: 5-90% of melamine hydrobromide, 5-75% of phosphinate, 5-15% of flame retardant synergistic agent and 0-5% of flame retardant synergist. The preparation method of the efficient precipitation resistant flame retardant composition is as follows: the powder or liquid of the phosphinate, the melamine hydrobromide, the flame retardant synergistic agent and the flame retardant synergist are fully and evenly mixed to obtain the highly efficient precipitation resistant flame retardant composition. The efficient precipitation resistant flame retardant composition of the invention can be used for polyethylene, polypropylene, polystyrene and various polyolefin copolymers, and is especially suitable for polypropylene, and the flame retarding grade can be up to UL94 V-0; and the efficient precipitation resistant flame retardant composition has high flame retarding efficiency, good fluidity and no precipitation, can meet the use requirements of flame retardant materials for use in building materials, electric appliance shells, sockets, bellows, lighting lamps and the like.

Description

technical field [0001] The invention relates to a high-efficiency precipitation-resistant flame retardant composition and a preparation method thereof, in particular to a high-efficiency precipitation-resistant flame retardant composition suitable for flame-retardant polyolefin materials and a preparation method thereof. Background technique [0002] Polyolefins include polyethylene, polypropylene, polyvinyl acetate, polystyrene and various olefin copolymers, among which polypropylene is used in the largest amount and is most widely used. Polypropylene (PP) has become one of the widely used general-purpose plastics because of its excellent comprehensive properties, good performance-price ratio, and wide processing and molding conditions. However, polypropylene is easy to burn, and its limiting oxygen index is 17.0-18.0%. It cannot be extinguished after being ignited in the air. Therefore, for facilities and places that are prone to fire, polypropylene must be flame-retardant...
