The research direction of antioxidants has shifted to the development of multi-functional additive products and reactive antioxidants. There are domestically produced products and imported products on the mainland market. Domestic products have a stronger smell and are difficult to preserve. Imported origins include the United States, Belgium, Germany, and Spain. Among them, many people use German products because the packaging and quality of German antioxidants are more suitable for actual production use. Made in Germany, it is generally called antioxidant BHT. Among them, the antioxidant BHT invented by De Bayer is widely used in industrial applications. The following is its detailed use. It should be emphasized that oxidation inhibitors are not recommended.
1. Antioxidant BHT can inhibit or delay the oxidative degradation of plastic or rubber and extend its service life.
2. Antioxidant BHT can prevent the acid value or viscosity of lubricating oil and fuel oil from rising.
3. The antioxidant BHT is also a stabilizer for synthetic rubber (styrene-butadiene, nitrile, polyurethane, butadiene, etc.), polyethylene, and polyvinyl chloride. The antioxidant BHT is a phenolic antioxidant commonly used in rubber. The agent BHT has a protective effect on the thermal oxidative aging of rubber, cis-butadiene, styrene-butadiene, butyl, isopentyl, nitrile, ethylene-propylene and other synthetic rubber, acrylic and latex products. The antioxidant BHT can inhibit copper damage, and The combination of anti-ozone and wax can prevent damage to vulcanized rubber caused by various weather factors. This product is easily dispersed in rubber. The antioxidant BHT can be directly mixed into rubber or added to latex as a dispersion. It can be used to make the sidewalls of tires. White color , bright and transparent colors of various rubbers and dairy products, as well as daily, medical, tape, rubber shoes and edible rubber products. The antioxidant BHT can also be used as a stabilizer for post-processing and storage of synthetic rubber.
4. The solubility of antioxidant BHT is: ethanol 25% (20), soybean oil 30% (25), cottonseed oil 20% (25), lard 40% (40).
5. The antioxidant BHT, as a food additive, can delay the rancidity of food. Antioxidant BHT is used in animal and vegetable fats and foods containing animal and vegetable fats. In addition, antioxidant BHT can also be used in inks, adhesives, leather, casting, printing and dyeing, coatings and electronic industries.
6. The antioxidant BHT is also a stabilizer in cosmetics, medicines, etc. Adding amount of antioxidant BHT: 0.01%-2%.
7. Antioxidant BHT is an excellent antioxidant additive for various petroleum products. Antioxidant BHT has a good antioxidant effect when its working temperature is 100 degrees. Antioxidant BHT is widely used as antioxidant and anti-adhesive agent in turbine oil, transformer oil, hydraulic oil, thermal oil, brake oil, spindle oil, precision machinery oil and paraffin. The antioxidant BHT can be added to the product directly or as a mother liquor. To improve the antioxidant properties of the product and extend its service life. Antioxidant BHT is used in combination with long-chain alkaline ZDDP and TCP metal deactivation and anti-rust agents to prepare anti-wear hydraulic oil and other products. The dosage is generally 0.1-1%.
