A silicon-based flame retardant

Abstract

The invention discloses a silicon-based flame retardant. The silicon-based flame retardant comprises sodium silicate, hydroxide Aluminum, sodium metaborate, ammonium polyphosphate and ammonium molybdate, the sodium silicate is sodium silicate with a modulus of 1.4-1.8. After the silicon-based flame retardant of the present invention is compounded, it has the effects of high-efficiency flame retardancy, non-toxicity, anti-melt droplet, smoke suppression, etc., and improves the surface activity of the sodium silicate flame retardant, which is beneficial to the flame retardant in the matrix. The dispersion in the medium improves the processing performance and mechanical properties of the material.

Description

technical field [0001] The invention relates to the technical field of flame retardants, in particular to a flame retardant for fiber fabrics, in particular to a silicon-based flame retardant. Background technique [0002] With the development of society and the improvement of living standards, the scope of use and consumption of textiles continue to increase. Fires caused by textile fires are also on the rise, causing loss of life and property. Therefore, it is necessary to improve the flame retardancy of textiles. [0003] Fabric flame retardants need to meet the following requirements: (1) can inhibit flame and flameless combustion at the same time; (2) use less, good flame retardant effect; (3) durable flame retardant, washable; (4) ) The flame retardant is harmless to the human body, and the fabric can be directly in contact with the human body after finishing; (5) The product of heating or burning is low-toxic and environmentally friendly; (6) The physical and mechan...

Problems solved by technology

[0006] Halogen-free flame retardants overcome the shortcomings of many traditional flame retardants, but in practical applications there are still problems with poor compatibility with polymers, which will adversely affect the physical and mechanical properties of composite materials and limit the composite materials. The scope of use of materials

[0007] In particular, as an inorganic flame retardant, silicon-based flame retardants have strong polarity and hydrophilicity, poor compatibility with non-polar polymer materials, and it is difficult to form a good combination and adhesion at the interface, resulting in the mechanical properties of the substrate. The performance and processing performance are damaged, which also greatly limits the application range of the substrate
