Analysis Of Halogen-Free Flame-Retardant Glass Fiber Reinforced Plastics Technology

< p > > Description: < a href= "//www.sjfzxm.com/news/index_c.asp" > glass fiber reinforced plastics < /a > is a kind of polymer glass fiber composite material prepared by corresponding polymer processing method.

Compared with general plastics, the rigidity, strength and heat resistance of GFRP plastics have been greatly improved.

< /p >

< p > usually most of the fiberglass reinforcements are used on the structural parts of the products. It is a structure < a href= "//www.sjfzxm.com/news/index_c.asp" > engineering material < /a >.

In view of the difficult technical problems of glass fiber reinforced plastics, which are the most widely used fiberglass reinforced plastics due to the wick effect caused by glass fiber, this technology combines the molecular design, synergistic effect, nano technology and coating technology of flame retardants, and develops a series of halogen-free flame retardants suitable for different glass fiber reinforced plastics.

< /p >

< p > technical advantages: it has the advantages of environmental friendliness, high flame retardant efficiency, low cost and low toxicity. The prepared glass fiber reinforced plastics have both flame retardancy and good mechanical properties.

< /p >

< p > taking GFRPA6 and GFRPBT as examples, the halogen free flame retardants produced by the technology of < a href= "//www.sjfzxm.com/news/index_c.asp > technology" /a "are added to 15%~25%, and the products with different thickness requirements (0.8mm~3.2 0.8mm~3.2) of V-0 grade can be tested by UL-94 vertical combustion. The material reaches 85%, and the mechanical properties of materials are more than that of the unflammable samples, which fully meet the requirements of daily vehicle, machinery and other fields.

< /p >

< p > on this basis, a more efficient and low cost flame retardant glass fiber reinforced plastic can be further prepared by using proper synergistic synergistic technology.

At present, the international community and China have further increased the standards of fire safety and the use of flame retardants, which require no halogen and low toxicity. This product can meet the requirements of automobiles, machinery, electronic appliances and other fields, and has obvious market competitiveness.

< p > glass fiber reinforced plastic has the advantages of light weight, high specific strength, corrosion resistance, good electrical insulation, slow heat pfer, good thermal insulation, excellent pient and ultra-high temperature performance, and easy coloring, and can pmit electromagnetic wave characteristics.

Compared with the commonly used metal materials, it has the following characteristics: < /p >

< p > because FRP products can be designed by ourselves according to different use environment and special performance requirements, so long as we choose suitable varieties of raw materials, we can basically meet the performance requirements of different uses for products.

Therefore, FRP is a kind of material that can be designed.

< /p >

< p > glass fiber reinforced plastic products, when making molding, is another distinguishing feature which is different from metal materials.

According to the design of the product and choosing proper laying methods and arranging procedures, the FRP materials and structures can be completed at one time, avoiding the two processing that metal materials usually require, thus greatly reducing the material consumption of the products and reducing the waste of human and material resources.

< /p >

< p > glass fiber reinforced plastic is also an energy-saving material.

If the manual paste method is used, the molding temperature is usually at room temperature or below 100 degrees Celsius, so its molding energy consumption is very low.

Even for mechanical molding processes, such as molding, winding, injection, RTM, ejection, extrusion and other forming methods, the molding energy consumption can be greatly reduced due to its molding temperature far below metal material and other non-metallic materials.

This technology is made from chemical properties.
