Definition and composition of Lu 'an Qingsong flame retardant masterbatch!

Lu 'an Qingsong flame retardant masterbatch is a kind of functional polymer material used to endue or enhance the flame retardant property of materials.

1. Basic information

Definition and composition

Lu 'an Qingsong flame retardant masterbatch is a granular product made of flame retardants, carrier resins and other additives (such as dispersants, lubricants, etc.) through high-speed mixing, twin-screw extrusion and other processes. Its main component flame retardants can be organic flame retardants (such as bromine flame retardants, phosphorus flame retardants) or inorganic flame retardants (such as magnesium hydroxide, aluminum hydroxide). The carrier resin is usually selected with a good compatibility with the flame retardant material, such as polyethylene (PE), polypropylene (PP), etc., its role is to provide a good dispersion medium for the flame retardant, so that the flame retardant can be evenly distributed in the material.

Appearance and form

Lu 'an Qingsong flame retardant masterbatch is generally granular, the particle size is usually about 2-5mm, the color is different due to the difference of flame retardants and carrier resins, common white, gray white, light yellow and so on.

Second, performance characteristics

High flame retardancy

The flame retardant in the flame retardant masterbatch of Lu 'an qingsong can play a role when the material burns. For example, when a material containing halogen-based flame retardant masterbatch burns, the flame retardant breaks down to produce hydrogen halide gas, which can trap free radicals during combustion and thus interrupt the combustion reaction. Phosphate-based flame retardant masterbatch is mainly produced during combustion of phosphoric acid and other substances, which can form a protective film on the surface of the material, isolating oxygen and preventing the continuation of combustion.

Inorganic flame retardant masterbatch such as magnesium hydroxide and aluminum hydroxide will decompose when heated, absorb a lot of heat, and release water vapor, which plays the role of cooling and diluting the concentration of combustible gas in the combustion area, so as to achieve the purpose of flame retardant.

Good dispersion

Due to the special processing technology, the dispersion of Lu 'an Qingsong flame retardant masterbatch retardant masterbatch in the matrix material is better. Compared with the direct addition of flame retardant powder, the flame retardant masterbatch can be more evenly distributed in the material, avoiding the phenomenon of flame retardant agglomeration, thus ensuring the stability and consistency of the flame retardant performance of the material. For example, in the plastic processing process, the flame retardant masterbatch can be uniformly dispersed with the flow of plastic melt, so that all parts of plastic products can obtain uniform flame retardant properties.

Compatibility with materials

Selecting suitable carrier resin can improve the compatibility between the flame retardant masterbatch and the flame retardant material. For example, in the flame retardant polyolefin materials, the use of polyolefin carrier resin of Lu 'an Qingsong flame retardant masterbatch can better combine with the polyolefin matrix, and will not cause the physical properties of the material (such as tensile strength, impact strength, etc.) to decline too much because of poor compatibility.

Superior processing performance

The granular form of Lu 'an Qingsong flame retardant masterbatch masterbatch makes it have good fluidity and metrology during processing. In the molding process of injection molding, extrusion, blow molding, etc.,Lu 'an Qingsong flame retardant masterbatch can be easily fed and processed like ordinary plastic particles, and can accurately control the addition amount, and will not cause damage to the processing equipment.

3. Application fields

Plastics industry

It is widely used in electronic and electrical plastic shells, such as computer cases and TV shells. The use of flame retardant masterbatches can make these plastic products meet the relevant flame retardant standards, such as the UL94 standard, improve the safety of electrical products and prevent the occurrence of fire accidents.

Also used for wire and cable insulation and sheath materials. Flame retardant masterbatch can enhance the flame retardant performance of wire and cable in fire, delay the spread of fire, and buy time for personnel evacuation and fire fighting work.

Rubber industry

The use of flame retardant masterbatch in rubber conveyor belts, rubber seals and other products can improve the flame retardant grade of rubber products. For example, in the coal mine conveyor belt, the flame retardant masterbatch can prevent the conveyor belt from producing open flame in the case of friction and so on, and improve the safety of coal mine production.

Fiber industry

For the production of flame retardant fibers, such as flame retardant polyester fiber, flame retardant polypropylene fiber, etc. These flame retardant fibers can be used to make flame retardant curtains, flame retardant work clothes and other products to meet the requirements of specific places (such as hotels, chemical enterprises, etc.) on the flame retardant properties of fabrics.
