Coating classification: antioxidant

Core tip: introduction to antioxidant products Antioxidants can prevent the oxidation of easily oxidized substances Antioxidant can improve the life of the coating and keep its initial high performance as much as possible The components of paint, adhesive, sealant or ink may be oxidized and degraded in the process of production, storage, transportation, application and final use Product picture product features ① It should have high oxidation resistance: ② good compatibility with resin, no precipitation; ③ good processing performance, no volatilization and no decomposition under the processing temperature of polymer; ④ good extraction resistance, no dissolution Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings news: antioxidant products brief introduction antioxidant can prevent oxidation reaction of easily oxidized substances Antioxidant can improve the life of the coating and keep its initial high performance as much as possible The components of paint, adhesive, sealant or ink may be oxidized and degraded in the process of production, storage, transportation, application and final use The product features: (1) high oxidation resistance: (2) good compatibility with resin, no precipitation; (3) good processing performance, no volatilization and no decomposition under the processing temperature of polymer; (4) good extraction resistance, no dissolution in water and oil; (5) the best color is colorless or light, so as not to pollute the product; (6) no toxicity or low toxicity; (7) low price Product classification 1 Aromatic amine antioxidant aromatic amine antioxidant, also known as rubber antioxidant, is the category with the largest production quantity This kind of antioxidant has low price and remarkable anti oxygen effect, but its application in light and white products is limited due to the discoloration of products It is mainly used in plastics , synthetic fiber, latex, petroleum products, food, medicine and cosmetics Important aromatic amine antioxidants include diphenylamine, p-phenylenediamine, dihydroquinoline and their derivatives or polymers, which can be used in natural rubber, styrene butadiene rubber, chloroprene rubber, isoprene rubber and other products 2 Hindered phenolic antioxidants hindered phenolic antioxidants are some phenolic compounds with space hindrance They have remarkable anti thermal oxidation effect, do not pollute products, and develop rapidly There are many kinds of these antioxidants The important products are: 2,6-tertiary butyl-4-methylphenol, bis (3,5-tertiary butyl-4-hydroxyphenyl) sulfide, tetra (β - (3,5-tertiary butyl-4-hydroxyphenyl) propionic acid) pentaerythritol ester, etc These antioxidants are mainly used in plastics, synthetic fibers, latex, petroleum products, food, medicine and cosmetics (the figure on the right shows the structure of hindered phenol antioxidant) 3 The auxiliary antioxidant THIODIPROPIONATE is a kind of auxiliary antioxidant, which is often used in combination with hindered phenol antioxidant, with remarkable effect, such as: THIODIPROPIONATE, often used in combination with hindered phenol antioxidant, with remarkable effect, the main products are: dodecyl alcohol ester, tetradecyl alcohol ester and dioctadecyl alcohol ester Phosphite is also an auxiliary antioxidant Its main products are: trioctyl ester, tridecyl ester, tris (dodecyl alcohol) ester and tris (hexadecanol) ester Product action mechanism 1 The stable coating house of polymer with chain breaking antioxidant is focused on coating, diatom mud, paint coating, coating process, news and coating of fire retardant coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fire retardant coating,
