Soft polyvinyl chloride (PVC) film flame retardant
With the development of the demand for the flame retardancy of electrical insulating tape in modern society, the requirements for the soft polyvinyl chloride (PVC) film flame retardant are also constantly updated.
We can learn from the selection principles of flame retardants in plastic industry, and develop new flame retardant systems combined with the technical requirements of soft polyvinyl chloride (PVC) film flame retardants, and get more new soft PVC (PVC) film flame retardants.
Halogen containing flame retardant made of soft polyvinyl chloride (PVC) flame retardant film due to release toxic hydrogen halide gas combustion, its application is restricted, especially the application of some closed environment, such as aircraft, high-speed rail, high-rise buildings and other requirements, not only flame retardant, but the smoke density is lower, and this only halogen free flame retardant system can be realized, so the soft PVC film (PVC) flame retardant halogen-free has become the trend in the development of large.
High efficiency compound halogen free flame retardant system. Through the synergistic action of halogen-free flame retardants combined with different flame retardant mechanisms, a highly efficient and low-cost composite halogen free flame retardant system has been developed. It has become a hot topic in the development of soft PVC (PVC) film flame retardant system.
The flame retardant efficiency can be further improved by mixing phosphorus flame retardant with metal oxide and heteropoly acid. On the one hand, phosphorus flame retardants can be effective through the flame retardation mechanism of gas phase and solidification phase. On the other hand, metal oxide and heteropoly acid can further improve their flame retardancy through catalytic carbon generation.
The phosphorus nitrogen flame retardant agent and silicon (including inorganic silica) mixed in intumescent flame retardant effect by using phosphorus nitrogen flame retardant, flame retardant silicone hand precipitation formed on the surface of Si-C insulation layer to protect the substrate, on the other hand can increase the strength of the carbon layer, improve the flame retardant efficiency.

Tris (1,3-Dichloro-2-Propyl) Phosphate (Flame Retardant TDCPP) Use:
The Product Has A High Efficiency Flame Retardant, Low Volatility, High Thermal Stability, Water Resistance, Alkali Stable And Soluble In Most Organic Substances, Processing Performance, With Plastic, Moisture, Anti-Static, Anti-Pull, Anti-Compression Performance. Widely Used In Unsaturated Polyester, Polyurethane Foam, Epoxy Resin, Phenolic Resin, Rubber, Soft Polyvinyl Chloride, Synthetic Fibers And Other Plastics And Coatings At High Temperature Pyrolysis, Can Be Used As Emulsifier And Explosion-Proof Agent.
By introducing non halogen elements, such as phosphorus and silicon, to the resin system of pressure sensitive adhesive, the products of the flame retardant pressure-sensitive adhesive have been developed. These products have unique advantages due to lack of powder additives, adhesion, long term weathering, electrical insulation and coating properties, and become new research hotspots.
Researchers at the Beijing University of Chemical Technology with acrylic polyether phosphate and acrylate by radical polymerization prepared with combined phosphorus acrylic copolymer solution intrinsic flame retardant properties, then the oily solution with ammonium polyphosphate slurry prepared with phosphorus flame retardant type acrylate pressure-sensitive adhesive, pressure-sensitive adhesive and flame retardant properties of the conventional performance and imported flame retardant pressure-sensitive adhesive is. The researchers at Southwest University of Science and Technology introduced the structure of phosphonitrile into acrylic resin structure (weight ratio of about 10%), and obtained halogen-free flame retardant acrylate PSA with excellent flame retardancy.
Flame retardant structure and bromine containing nitrogen brominated flame retardant agent three triazine structure (such as: three (three bromo phenyl) cyanuric acid ester, TTBPC), due to the synergistic effects of intra molecular bromine nitrogen element, the flame retardant efficiency is higher than the ordinary brominated flame retardants, can reduce the amount of people have tried to use.
Brominated flame retardants are widely used in flame-retardant pressure-sensitive adhesives because of their high flame retardancy efficiency, stable performance and excellent performance. But because of its high cost and halogen, it has a tendency to be replaced gradually, but at present, it still occupies an important position.
The typical products of inorganic flame retardants are hydroxides, including aluminum hydroxide and magnesium hydroxide. These flame retardants are capable of achieving flame retardancy by decomposing and absorbing heat and producing large amounts of inert gases and blocking oxygen.
This kind of flame retardant has the advantages of low cost, good flame retardancy, low smoke and no halogen-free. But the addition amount is large, in the solid component, the content is more than 60%, it has the flame retardant effect, so the performance of the adhesive is poor, used in some low end fields.
In order to make up for the lack of flame retardancy of pure inorganic hydroxides, people are able to reduce the total consumption and efficiency by compounding the gas phase flame retardant mechanism of nitrogen flame retardants, such as MCA, so that they can be used in some high-end fields.
Expandable phosphorus and nitrogen halogen free flame retardant. Generally, the system is mainly composed of II type APP (ammonium polyphosphate). APP as an acid source and carbon source (pentaerythritol) and gas source (melamine) form an intumescent flame retardant system. It forms porous carbon layer during combustion, blocking heat and oxygen and giving full play to the flame retardant effect.
The cost of this kind of product is middle, the flame retardant effect is good, and the amount of addition is moderate, and the amount of addition is about 40% in the solid component. In order to improve the flame retardant efficiency, the researchers also synthesized and mixed some high efficient carbon agent, to replace the ordinary carbon source, can greatly reduce the dosage of flame retardant agent, the cost is not increased significantly.
For example, the NHFR-100MT type expansive non halogen flame retardant used in the flame retardant pressure-sensitive adhesive is excellent. The quality of APP products, such as the degree of polymerization and purity, the solubility in water and the viscosity stability of the products, affect the application performance of these products.
