Epoxy resin cable flame retardant
With the rapid development of the national economy, the application of epoxy resin cable flame retardant is becoming wider and wider. In this paper, some commonly used epoxy resin cable flame retardants are introduced.
Epoxy resin cable flame retardant 1. Antimony flame retardant
Advantages: three oxidation of two antimony can not be used alone as a flame retardant, and combined with the appropriate halogen compounds, it can play a particularly effective flame retardancy. Disadvantages of antimony flame retardant synergistic mechanism of heavy metals, toxic, and arsenic homologues in crude product containing arsenic and other heavy metals, arsenic trioxide. It can not be used as green fillers and green flame retardants.
Epoxy resin cable flame retardant two, aluminum hydroxide flame retardant (ATH)
Advantages: low price, good flame retardancy.
Disadvantages: poor heat resistance, dehydration at 200 DEG C, dehydration at 330 to 350 C, and dehydration of resin in aluminum hydroxide dehydration temperature range, resulting in foaming of finished resin products, uneven surface and dielectric properties, and low yield. It is used in high temperature to cause silica fogging, and the product is bleb, dielectric loss and so on. EC is 60~100 S/cm, easy to absorb moisture.
Epoxy resin cable flame retardant three, magnesium hydroxide flame retardant
Advantages: the application of magnesium hydroxide flame retardant (430 centigrade decomposition) nontoxic
Shortcomings: Acid - resistant, acetic acid can dissolve magnesium hydroxide, only suitable for low grade products. Easy to absorb moisture, poor dispersion and poor dielectric property.
Epoxy resin flame retardant cable four, high heat-resistant boehmite flame retardants (Boehmite, ALOOH)
The advantages are as follows: 1%, the dehydration temperature is above 350 degrees, the dehydration at 500 dehydration reaches the peak value, EC<50 S/cm, and the dielectric strength is strong. It solves the problem of the defect and dielectric loss of aluminum hydroxide due to the low dehydration temperature, and it has strong acid and alkali resistance.
Shortcomings: flame retardancy is slightly lower than aluminum hydroxide, to achieve the same flame retardant performance need to be added. But its biggest feature is high heat resistance, thermal conductivity, acid alkali resistance, high heat resistant functional material can improve the added value of product.
The day before, adding inorganic flame retardant magnesium hydroxide with special morphology through the identification, in our country environmental protection flame retardant on the road and a step forward. Magnesium hydroxide flame retardant is a filled and inorganic flame retardant. It can be widely applied in the fields of epoxy, polypropylene, polyethylene, polyvinyl chloride, high impact polystyrene, ABS and other plastics and rubber. Compared with the organic bromine flame retardant, magnesium hydroxide flame retardant is a kind of environmental protection material. As an inorganic flame retardant, magnesium hydroxide has many advantages compared with aluminum hydroxide.

Flame retardant TPP has many advantages, such as excellent transparency, softness, bacterial resistance, and water proof, grease-proof, good electric insulation, as well as good compatibility. Flame retardant TPP is mainly used as the flame-retardant plasticizer for cellulose resin, vinyl resin, natural rubber and synthetic rubber. And it may also be used as the flame-retardant plasticizer for glyceryl triacetate thin ester and film, rigid polyurethane foam, phenolic aldehyde resin, and PPO, etc.
Flame retardant TPP is a kind of halogen-free environment-friendly flame retardant with phosphorus element. Most of the products in the market are self-colored flaky crystal, our product is self-colored crystalline powder, and is more soluble in organic solvents. TPP is not soluble in water, but soluble in benzene, chloroform, ether and acetone, and slightly soluble in Z alcohol. Flame retardant TPP is nonflammable with slight aromatic odor and slight deliquescence. The fusion point is about 50 ℃, and fast melts to hoop-shape when heated. The lubricate effect is excellent, and it is often used as the flame retardant plasticize lubricant. What is more, it is used as the flame retardant for many plastics and resins, such as phenolic aldehyde resin, epoxy resin and so on.
The results of research on surface modification of magnesium hydroxide superfine powder and modified magnesium hydroxide. After flame retardant formulations filled by an ethylene vinyl acetate copolymer (EVA) resin, the optimum conditions were determined by study on flame retardant properties and mechanical properties of composite materials. It was tested by authoritative department. The EVA composite material prepared by this process has a flame-retardant oxygen index greater than 30%, a tensile strength greater than 10 MPa, and a elongation at break greater than 150%.
Epoxy resin flame retardant FR-108 is white powder, no halogen-free environmental protection, in line with the EU environmental protection standards.
1. The flame retardant efficiency is high, which can give the resin material good self extinguishing or flammability.
2. It has good compatibility and good compatibility with resin materials and easy to disperse.
3, it has high decomposition temperature and does not decompose at the processing temperature of the resin material.
4, non-toxic, no odor, no pollution, in the process of flame retardant do not produce toxic gas.
5. When used with resin materials, it does not reduce the mechanical properties, electrical properties, weatherability and thermal deformation temperature of the resin materials.
6, good durability, can be retained in the resin materials for a long time, play its flame retardancy and low price. This product is a kind of added phosphorus and nitrogen flame retardant, which can be widely used in epoxy resin, polyurethane, acrylic acid and organosilicon. As a flame retardant of epoxy resin, this product is especially suitable for flame retardant components and components.
The three azinazine flame retardant has the advantages of small volatility, excellent flame retardancy, non-toxic, good compatibility, durable and light resistance. Therefore, three azine derivatives are constantly synthesized to be used for the flame retardancy of a variety of synthetic materials. For example, polystyrene with brominated three - azine flame retardant has high impact resistance in addition to excellent flame retardancy. The research on the synthesis and application of three azine flame retardants at home and abroad is very active, and a large number of papers and patents have been published.
ABS has excellent electrical properties, cold resistance, oil resistance, chemical stability and impact performance. It is widely used in mechanical and electrical, electrical appliances, transportation and other industries. However, the oxygen index of ABS is only 17.8. It can continue to burn after the fire and release a lot of black smoke and toxic gas. The electronic and electrical fittings made by it will cause fires due to short circuit. The demand for flame retardancy of plastics is increasingly strict in the electrical industry. Therefore, the promotion and application of ABS without flame retardancy has been severely restricted. Improving the flame retardancy of ABS resin has become a problem of great concern and urgent need in today's society. Many experts and scholars at home and abroad have done a lot of research in this field.
