Unsaturated resin flame retardant
Definition of unsaturated polyester resin. Resin is divided into thermoplastic and thermosetting resin. The resinous resins that can be reheated are called thermoplastic resins, such as polyvinyl chloride (PVC), polyethylene resin (PE), etc. When heated, it is no longer reversible. It is a solid that is neither dissolved nor melted. It is called thermosetting resin, such as phenolic resin, epoxy resin, unsaturated polyester resin, etc.
Organic unsaturated resin flame retardant is mainly halogen flame retardant, and halogen unsaturated resin flame retardant is divided into two categories: chlorine and bromine. The bromine is the most important and effective of halogen unsaturated resin flame retardants with high flame retardancy, good thermal stability and little addition. At present, the development of bromine flame retardant has reached more than 80 species, in the late 90 s has accounted for the sales of bromine series flame retardant polymer additives 35% of total sales, and the trend of increase year by year.
The first resins discovered by humans are fat extracted from tree secretions such as rosin and so on. This is the reason for the "tree" before "fat". It was not until 1906 that a new era of artificial synthetic resins was created by artificial synthesis of phenolic resin. The American rubber company first produced unsaturated polyester resin in 1942, which later called any polymer that was not processed as resin. But it has nothing to do with trees.
"Polyester" is a class of high molecular compounds containing ester bonds relative to the resin such as "phenolic" and "epoxy". This kind of high molecular compound is generated by binary acid and glycol via polycondensation reaction, and the polymer compounds containing unsaturated double bond, is called unsaturated polyester, this kind of unsaturated polyester dissolved in the aggregation ability of monomer (styrene).
And become a kind of viscous liquid, referred to as the Unsaturated Polyester Resin (English name Unsaturated Polyester Resin UPR). So saturated and unsaturated polyester resin can be defined as the dibasic acid unsaturated and saturated or unsaturated, and the glycol polycondensation of linear polymer compounds dissolve in monomer (usually with styrene) and sticky liquid.
Unsaturated polyester resin properties
Unsaturated polyester resin is a kind of thermosetting resin, which can solidify into an insoluble polymer mesh polymer when it is used in heat or initiator. But this kind of polymer mechanical strength is very low, cannot satisfy the requirement of most use, can become a kind of when using glass Fiber Reinforced composite material, commonly known as "glass" (English name Fiber Reinforced Plastics FRP). The mechanical strength of "glass steel" has been improved greatly compared with the resin casting body.
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.
The unsaturated resin-base glass reinforced plastic (upr-frp) has the following characteristics:
1. Light quality:
The density of FRP is 1.4 ~ 2.2 g/cm3, which is 4 ~ 5 times lighter than steel, but its strength is not small, it is stronger than steel, hard aluminum and fir. This is of great importance for products such as aviation, spaceflight, rocket, missile, ordnance and transportation, which need to reduce their weight. For example, the Boeing 747 jetliner has 2.2 tons of FRP parts applied to its main structure, effectively saving aircraft fuel, increasing speed, extending the duration and increasing the payload. Performance of upr-frp and other materials:
2. Good corrosion resistance:
Upr-frp is a good corrosion resistant material, and can withstand the acid, alkali and salt of general concentration. Most organic solvents, seawater, atmosphere and oil are also very resistant to microorganisms. It is widely used in the fields of petroleum, chemical industry, pesticide, medicine, dye, electroplating, electrolysis, smelting, light industry, etc., which exerts an irreplaceable role in other materials.
3. Excellent electrical performance:
Upr-frp insulation is excellent and can maintain good dielectric properties under high frequency. It does not reflect radio waves, it is not subject to electromagnetism, the microwave is good through sex, it is the ideal material for making radar enclosures. It can improve the service life and reliability of electrical appliances by making the insulation components in instruments, motors and electrical appliances. Dielectric properties of upr-frp:
Volume resistivity (Ω cm) dielectric strength (KV) mm - 1 dielectric constant (60 hz) power factor (60 hz) arc resistance (S)
1012 ~ 1014 15 ~ 20 3.0 ~ 4.4 0.003 125
4. Unique thermal performance:
UPR - coefficient of thermal conductivity of FRP is 0.3 ~ 0.4 Kcal/mh ℃, only metal 1/100 ~ 1/1000, it is a good thermal insulation material, made of the doors and Windows is the fifth generation of new energy-saving building materials. In addition, the FRP line expansion coefficient is also small, which is close to the normal metal material, so the FRP and metal connection are not subjected to thermal expansion to produce stress, which is conducive to bonding with metal substrate or concrete structure.
