Environmental composite stabilizer compound stabilizer _ _ Extension-Technology

Liquid barium cadmium zinc composite stabilizer due to the composition of different nature are different. But it is generally pale yellow to yellow clear liquid at room temperature, specific gravity 0.95 to 1.02, a viscosity of less than 100 cps, freezing point at -15 ℃. Liquid barium cadmium and barium cadmium zinc liquid similar to have good heat, light stability, initial color small lead, barium composite stabilizer, good transparency and color stability. Their stabilizing effect than solid composite soaps strong Shandong composite stabilizer, so the amount can be reduced, typically 2-3 parts, dust poisoning does not occur, and is completely dissolved in the general plasticizer, good dispersion, Little precipitation tendency. Wherein the liquid barium cadmium zinc early color is smaller than some liquid barium cadmium. Non-metallic organic heat stabilizers, such as β- aminocrotonate, 2-phenyl-indole, triphenyl urea, etc., has been used as nontoxic stabilizers subject compound stabilizer, but the high temperature, long-term heat resistance , light composite stabilizer poor offer, has been rarely used. In recent years, according to the environmental-friendly and non-toxic and harmless request, committed to pure heat stabilizer of organic metal-free, have achieved good results. For example, Ciba Specialty Chemicals has developed amine pyrimidinedione organic heterocyclic ring as the core of heat stabilizers for rigid PVC pipe extrusion. Hot lead salt stabilizer can achieve stable performance. Again, Morton developed an active organic sulfur compounds characterized by pure organic heat stabilizers can replace cadmium-based and Ba / Zn in soft PVC products processing, Ca / Zn heat stabilizer system liquid compound heat stabilizer made of an organic metal soaps type, phosphite, hindered phenol antioxidant and a solvent. The organic metal soap is the main component of liquid composite stabilizer. Metal soaps used are cadmium / barium / zinc, barium / zinc, calcium / zinc and the like; organic acids used are caprylic acid, oleic acid, naphthenic acid, synthetic fatty acid, benzoic acid, salicylic acid and the like. Admixed phosphite have triphenyl phosphite, phenyl phosphite, diisooctyl a bisphenol A diphosphite alkyl ester (PL-40) and oligomer (PL-440) and so on. Bisphenol A commonly used antioxidant or a hindered phenol antioxidant. The solvent for the plasticizer, higher alcohols, higher alkanes. Main commodities liquid barium / cadmium / zinc, barium / cadmium, calcium / zinc and barium / zinc and other composite stabilizer, respectively for soft PVC calendered film, rigid PVC transparent sheet, PVC transparent bottles. Because more varieties, different composite components, specific dosage and precautions should be relevant enterprises to understand the environmental composite stabilizer compound stabilizer _ _ Rio Tinto intelligent technology provided by the Qingdao-Technology Co., Ltd.
