Diacetone acrylamide coating crosslinking agent
2017-4-12 20:05:36
Diacetone acrylamide coating crosslinking agent,Because most of the crosslinking of the active groups in the water stability is bad, 1999 reports of active monomers has excellent stability in water, namely, N - (1, 1 - dimethyl - 3 - butyl oxygen) acrylamide, commodity name diacetone acrylamide, melting point 57 ℃, soluble in water, relatively non-toxic. Its main advantage is that can be crosslinked at room temperature, and have good film performance, and stability in the water system.
Diacetone acrylamide is a chemical formula is C9H15NO2.
Diacetone acrylamide English alias: 2 - PROPYLENAMIDE, N - (1, 1 - DIMETHYL - 3 - OXOBUTYL); 4 - Acrylamido - 4 - methyl - 2 - pentanone; ACRYLAMIDE, N - (1, 1 - DIMETHYL - 3 - OXOBUTYL); DAA. N - (1, 1 - DIMETHYL - 3 - OXOBUTYL) ACRYLAMIDE; 2 - Propenamide, N - (1, 1 - dimethyl - 3 - oxobutyl) -; N - (1, 1 - dimethyl - 3 - oxobutyl) - 2 - propenamid; N - (1, 1 - Dimethyl - 3 - oxobutyl) - 2 - propenamide; N - (1, 1 - dimethyl - 3 - oxobutyl) - acrylamid; N - (2 - (2 - Methyl - 4 - oxopentyl)) acrylamide; N - (2 - (2 - methyl - 4 - oxopentyl) acrylamide and n, n - bis (2 - oxopropyl) - 2 - propenamid; n, n - diacetonyl - acrylamid; DAAM; CmcSodiumSalt (EdifasB); Diacetone acrylamide (stabilized with MEHQ + TBC); 2 - (Acryloylamino) - 2 - methyl - 4 - pentanone
Acrylamide is a white crystal chemical, is the production of polyacrylamide raw materials. Polyacrylamide is mainly used for the purification of water, pulp processing and pipe internal coating, etc, also used in polyacrylamide gel electrophoresis. Starchy foods under high temperature (> 120 ℃) cooking to produce acrylamide.
Studies have shown that the human body through the digestive tract, respiratory tract, skin and mucous membrane contact acrylamide, drinking water is one of the important way of contact. In April 2002, the Swedish national food administration and the university of Stockholm, the researchers first reported in some Fried starchy food and barbecue, such as French fries, potato chips in the checkout acrylamide, and content of more than 500 times more than allow maximum limit in drinking water. After Norway, Britain, Switzerland and the United States and other countries have reported similar results. In addition, the human body can also contact through the way such as smoking, acrylamide.
Chinese name: Diethyl toluene diamine(DETDA)
Diethyltoluenediamine Uses:
The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.
Acrylamide into the body and can be absorbed by human body through a variety of ways, including through the digestive tract absorb the fastest. Enter the body of a person about 90% acrylamide is metabolic, only a small amount to prototype via the urine.
Acrylamide after entering the body, will and guanine in DNA in the body to form adducts, cause gene mutation genetic material damage. Crowds and accidental contact acrylamide career acrylamide exposure population survey, acrylamide have neurotoxic effect, but also do not have enough evidence that through food intake of acrylamide have obvious relationship with the occurrence of certain human tumors.
Acrylamide is a kind of unsaturated amide, alias AM, its monomer is colorless transparent sheet of crystallization, the boiling point of 125 ℃ (3325 pa), melting point of 84 ~ 85 ℃, the density of 1.122 g/cm3. Soluble in water, ethanol, ethyl ether, acetone, chloroform, insoluble in benzene and heptane, can be hydrolyzed into acrylic acid in the acid and alkali environment.
Is organic monomer of synthetic material, production of pharmaceutical intermediates, dyes, paint. Acrylamide monomer is stable at room temperature, but when at or above the melting point temperature and oxidative condition and under the action of uv polymerization is easy to occur. When heating to dissolve the acrylamide release strong corrosive gas and nitrogen oxide compounds.
Polyacrylamide is water-soluble polymer, insoluble in most organic solvents, has good flocculation sex, can reduce the friction resistance between liquid, by ion characteristic points can be divided into non-ionic and anionic, cationic and amphoteric four types.
