Description
Technical field
The invention belongs to the rubber ingredients technical field of material science and technology fine chemistry industry, especially a kind of DEDB softening agent.
Background technology
Softening agent is the maximum auxiliary agent of consumption during plastic working such as PVC is produced, if without softening agent, it is very hard, frangible that PVC will become, and can't satisfy the pliability or the snappiness requirement of plastics in the productive life.Softening agent can be widely used in makes electric wire and cable jacket, leatheroid, agricultural film, calendered film, foam article, floor and laminated product, sole, sheet material, pavement, plastic floor and asbestos floor, disc and film sheet base, tubing, foam materials, moldings such as pouring piece and injection member etc., in coating, tackiness agent, pigment and spices, also can make softening agent and use.DOP (DOP) is the most frequently used a kind of in the conventional plasticizers, and DOP had reached 2,000,000 tons at the consumption of Chinese market in 2008, and annual market capacity is about 20,000,000,000 Renminbi.But DOP also is simultaneously a kind of tool poison hazardous substances, and its main harm is to influence upgrowth and development of children.
Played formal enforcement " European Union registers, assesses, authorizes the rules of restriction about chemical " (being called for short the REACH rules) on June 1st, 2009; Further improved European Union's chemical import threshold, REACH control is that, tool toxicity big by quantity, detrimental substance begin in proper order.1400 kinds of tool toxicity, hazardous property are arranged in the basic chemical substance of kind more than 30,000 approximately, be called high pay close attention to material (Substance of Very High Concern, SVHC).SVHC is meant that the scientific evidence proof may cause the material (like endocrine regulation) of serious harm to " environment " or " human health ".
Finally announce first wave height and pay close attention to the material short-list in the REACH instruction down of attracting attention of many institutes, wherein electronics industry brominated flame retardant (BFR), phthalic ester (Phthalates) and arsenic compound commonly used is by included.
From long-range viewed; The increasingly high productive life of Along with people's needs, the needs of health care; People more and more tends to use green product little to environmental influence, that be harmless to the health, and its demand will significantly rise, and the market of environment-friendly plasticizer will be more and more wide.
