Properties: the product is a white powder, heated to 200 degrees Celsius, sublimation, room temperature can be ignited by flame, insoluble in ether, aromatic hydrocarbons, etc..
Uses: mainly used for radial tire, a reinforcing resin as curing agent, improve the hardness of rubber products; two with resorcinol additives together constitute the adhesive system on the adhesion of rubber and fiber plays an important role.
Packing: packed in woven bags of plastic bags, net weight of each bag is 20kg. accelerator
Storage: storage in the room, dry and ventilated, anti high temperature, fire, storage period is half a year. Over the storage period, the qualified can still be used.
Promoter species complex, difficult for unified classification, this paper classified according to various kinds of adhesive for accelerator.
The accelerators for epoxy resins
A, DMP-30, EP-184 fatty amine, triethanolamine etc.
B, anhydride accelerator: BDMA, CT-152x, DBU, etc.
C, polyether amine catalyst: EP-184399, etc.
D, latent catalyst: K-61B, CT-152X, etc.
The polyurethane adhesive for accelerator
A, the amine accelerator: three ethylene two amine, A-1, A-33, DC-829 etc.
B, tin accelerator: two, two, butyl tin, tin, tin, CT-E229, etc.
The phenolic resin adhesive accelerator (stannous chloride, ferric chloride, the chloro benzoic acid, accelerator M).
The unsaturated polyester resin adhesive accelerator (cobalt naphthenate, cobalt isooctanate, octanoic acid, zinc, N, N- two, N- two N methyl aniline, ethyl aniline, vanadium phosphate etc.).
The rapid curing acrylic structural adhesive accelerator (NA 22, four methyl thiourea, acetylacetone vanadium acetylacetonate, phenyl phosphine, three, butyraldehyde aniline condensation compound 808, two benzyl methylamine).
Such as accelerator for anaerobic adhesives (N, two N-, three of methyl aniline methyl ethylamine, hydrogen quinoline, 8- hydroxyquinoline, saccharin, two ferrocene, three aluminum acetylacetonate).
, rubber and rubber adhesive accelerator (accelerator D, DETU, DPG, M, TMTD, BZ, PZ, ZDC, CZ). Mechanism and effect: vulcanization accelerator. Substance capable of promoting vulcanization. Can shorten the curing time of rubber or reduce the curing temperature, reduce the amount of curing agent and improve the physical and mechanical properties of rubber, etc.. Can be divided into two categories: inorganic accelerator and organic accelerator. Inorganic enhancers, in addition to Zinc Oxide, Magnesium Oxide, such as the use of a small amount of lead, the rest is mainly used as accelerators. Use most of the organic accelerator. Various types. Some of the bitter accelerator (such as accelerator M), some of the products (such as color Thiofide D, some) (such as vulcanization accelerator TT), with some anti-aging effects or plastic solution effects (such as accelerator M) etc..
Effect of speed: according to the operation speed, can be divided into slow and medium speed, speeding, speeding, speeding ultra accelerator. In addition, there are delayed action accelerator etc.. Is mainly organic compounds containing nitrogen and sulfur, with aldehyde amine (such as accelerator H), guanidine (such as accelerator D), thiurams (such as accelerator TT), thiazole (such as accelerator M), two dithiocarbamate (such as accelerator ZDMC), xanthate (such as accelerator ZBX) and thiourea (such as accelerator NA-22) and sulfonamide (such as accelerator CZ) etc.. According to the specific circumstances of the specific circumstances alone or mixed use.
