Heat stabilizer is the synergistic effect of the main metallic soap centered, cooperation between metallic soap, metal soap and epoxy compound, metal soap and phosphite, metal soap and polyols.
Metal soap is highly active and low activity.
For cadmium zinc soap, soap, such as highly active soap, when used alone, the chlorine atom has strong displacement ability, can very good restrain in the early period of the resin injection tooling coloring, but generated after displacement metal chloride can activate PVC molecular chain of C -
CI keys, and promote the HCI reaction, so late hue is very poor.
With sharp black PVC late caused by zinc soap, burning phenomenon known as zinc.
is mainly used as auxiliary heat stabilizer plasticizer type epoxy compounds, commonly used varieties of epoxy soybean oil, epoxy stearic acid ester, epoxy four hydrogen phthalate and glycidyl ether, etc. Epoxy compound used as a stabilizer, alone application performance is poorer, but when used with other heat stabilizers, has a good synergistic effect. Cadmium/barium/zinc complex stabilizer and especially when the effect is particularly prominent. Other auxiliary heat stabilizer and polyols, which with the main thermal stabilizer and have certain effect to improve the thermal stability of PVC.
due to the varieties of heat stabilizer is various, performance is different, can according to the requirements of the products when formula to choose properly choose, molding process and equipment characteristics, to produce excellent performance, low cost products. Separately using a heat stabilizer are sometimes difficult to meet the requirements or the thermal stability of low efficiency, when two or more heat stabilizer used, can greatly increase the efficiency of the thermal stability and the synergistic effect is the thermal stabilizer.
composite heat stabilizer, mean organic metal salts, phosphite ester, polyol, antioxidant and solvent such as multicomponent mixture, in liquid form. Using the composite heat stabilizer has the advantages of convenient, clean and efficient. Metal soap heat stabilizer is the main element of the composite heat stabilizer. Used as antioxidant with bisphenol A, solvent generally available mineral oil, fatty alcohol, liquid paraffin or plasticizer, etc. Because each manufacturer materials in manufacturing methods are not the same, the same formula of liquid composite stabilizer in composition, there are big differences in properties and USES, etc.
the ideal heat stabilizer should possess the following basic conditions: the thermal stability of high efficiency, and it has good light stabilizer; Good compatibility with PVC, volatile small, sublimation, don't move, difficult to be water, oil or solvent extraction. Has the proper lubrication, to make products in calendaring easy stripping from the roller, do not scale; Do not react with other additives, not be copper or sulfur pollution; Don't reduce the product's performance, printing, high frequency welding and bonding and other secondary processing performance; Non-toxic, odourless, no pollution, can be made transparent products, processing and convenient use, low price.
some separate some compounds used as heat stabilizer, performance is insufficient, if you cooperate with other types of heat stabilizer, can produce a good application effect. Especially with phosphite ester, epoxy compound use is more, they are often referred to as the organic auxiliary heat stabilizer. Phosphite ester peroxide decomposition agent, in polyolefin, ABS, polyester and synthetic rubber is widely used as auxiliary antioxidants.
as auxiliary heat stabilizer, phosphite ester used with metal soap, can improve the heat resistance of injection molding processing products, transparency, compression resistance, weather resistance and other performance. Mainly used in PVC alkyl aryl phosphite phosphate ester, the effect of metal ions, replacement allyl chloride, spread to catch hydrogen chloride, at the same time have a decomposition peroxide and interaction with the polyene bonus. Phosphite ester is widely used in liquid composite heat stabilizer, the general amount to 10% 30%; Used for agricultural film, artificial leather and other soft products, the dosage of 0. 3 - 1; In the hard ware dosage is 0. 3 - 0. Five copies.
