Rubber auxiliaries knowledge

Rubber additives include *chemicals, accelerators, active agents, anti-scorching agents, anti-aging agents, reinforcing agents, fillers, plasticizers, coloring agents, foaming agents, and latex compounding agents. Rubber accessories include: sulfur, zinc oxide, magnesium oxide, paraffin wax, light-colored solid marlon, dark solid marlon, stearic acid, zinc stearate, titanium dioxide, **, light calcium, clay, barium sulfate, hard Fatty Acid, White Ointment, Lithol, Red Antioxidant 2246, Foaming Agent H.

The nature of the antioxidant is: rubber anti-aging agent Alba

Chemical name: 2,5-di-tert-butylhydroquinone; 2,5-di-tert-butylhydroquinone; 2,5-di-tert-butyl hydroquinone; NS-7; English abbreviation: DTBHQ

Molecular formula: C14H22O2

Molecular weight: 222.2

Performance: This product is white or light yellow crystalline powder, specific gravity 1.09, soluble in alcohol, ketone, ethyl acetate and carbon dioxide, slightly soluble in benzene, gasoline, insoluble in water.

Use range:

Alba is widely used in synthetic rubber, plastic, and resin industries. Applicable to natural rubber, synthetic rubber and latex, polyolefins and polyoxymethylene and other plastics, resins and engineering plastics modified UV absorbers; all kinds of rubber, developing materials, resins, plastics, oils and adhesives. It is a non-toxic, non-perfect odor, non-polluting plastic and resin polymerization inhibitor. Alba acts as an inhibitor, especially as an antioxidant in a low-pressure environment. Alba makes the unsaturated polyester very stable during production and storage.

Used as an anti-emulsion for natural rubber, synthetic rubber and latex, it can retard the oxidation and ultraviolet light aging of plasticized and non-gelatinized rubber. It is a non-polluting rubber product, does not discolor in sunlight, has no coloration, and is non-polluting. The antioxidant is superior to the usual antioxidants in terms of oxidation resistance, and can also improve the heat resistance and flex cracking resistance of rubber products. The effective addition amount is 0.1-2%. This product is also good for anti-aging effect of adhesives. It is also used to make light-colored rubber products, medical supplies, dairy products, and adhesive tapes.

It can also be used as an antioxidant for oils and synthetic resins. It can be used as a heat and light stabilizer for polyolefins and polyoxymethylene in the plastics industry.

advantage:

It can delay the oxidation, aging and ultraviolet light aging of the plasticizer, and does not pollute the product; it can improve the heat resistance, oil resistance and crack resistance of the rubber products; it is easy to disperse and has no effect on the conversion. Particularly suitable for the manufacture of light-colored rubber products, medical supplies, latex products and adhesive tapes, Alba is a widely used effective inhibitor; has sufficient solubility and chemical stability in polyester solvents; does not affect the resin Physicochemical properties; very few dosages can achieve good results.
