The stabilizer blend that does not contain or do not contain substantially any phenolic antioxidant that the present invention relates to select.Some polyacrylic manufacturer adds usually＜a small amount of phenolic antioxidant of 0.01% (by weight), and to support the initial production of acrylic resin.The consumption 0.05% (by weight) of the amount that remains in the phenolic antioxidant in the resin that is used for preparing polypropylene fibre phenolic antioxidant in the operation embodiment of US-A-4 876 300.Used in the context of the present invention term " does not contain or does not contain substantially phenolic antioxidant " and refer to can contain 0-0.01% (by weight) phenolic antioxidant in composition of the present invention.In order to reach described stablizing effect, specially in composition of the present invention, do not add phenolic antioxidant.
Another most important aspect of the present invention is to improve the smoked fadedness of anti-gas and reduce the generation of polypropylene fibre color and do not lose any other method of stability characteristic (quality), and it is to reach by the stabilizer blend that mixes above-mentioned effective stable quantity.
Another aspect of the present invention is a method of improving the degraded of polypropylene fibre ultraviolet radiation resisting, and this method is by mixing the stabilizer blend of above-mentioned effective stable quantity in fiber, thereby is better than the effect of using conventional stabilizing agent to reach separately.
Another aspect of the present invention is the method for Reinforced Polypropylene fiber heat endurance, and this method is by mixing the stabilizer blend of above-mentioned effective stable quantity in fiber, thereby is better than the effect of using conventional stabilizing agent to reach separately.
Above-mentioned bulky amine and phosphite ester can have been bought on market usually maybe can adopt the method preparation of having announced.
Adopt the disclosed hydrogen peroxide direct oxidation N that uses among US-A-4 782 105, the US-A-4 898 901, particularly US-A-5 013 510, the method for N-two (hydrogenated fat) amine prepares N, N-dialkyl group azanol.
The additive that polypropylene fibre also can contain other is filler and reinforcing agent for example, for example calcium carbonate, silicate, glass fibre, asbestos, talcum, kaolin, mica, barium sulfate, metal oxide and hydroxide, carbon black, graphite, with other additive, for example plasticizer, lubricant, emulsifying agent, pigment, fluorescent whitening agent, fire retardant and antistatic additive.
Conventional stabilising system, the phenolic antioxidant that for example has phosphite ester and sterically hindered amine stabilizer, or the phosphite ester with sterically hindered amine stabilizer can provide fabulous stablizing to polypropylene fibre in selected performance range, but, have only the ternary composition of the selected bulky amine of the application of the invention, selected azanol and selected phosphite ester just can make all important performance optimizations of stablizing polypropylene fibre.
Polypropylene is widely used in produces family expenses, commercialization and the automobile fiber with woollen blanket.The fiber of white and light color can fade and variable color owing to gas is smoked.Described resin may contain very a spot of stable phenolic antioxidant that is used for during the acrylic resin initial production before making fiber.In all cases, before making fiber, it also is possible in the acrylic resin that stabilizing agent group that must some are other is added to.As everyone knows, by generating oxidation product-quinones chromophore or owing to be exposed in the nitrogen oxide environment (being called " gas is smoked to fade "), position phenol resistance anti-oxidant is the main cause of this variable color.
Therefore, preferably from polypropylene fibre, the phenolic antioxidant component is removed.Regrettably, when the past handled like this, other characteristic that relates to polymer stabilizing was adversely affected.Phenolic antioxidant in high-temperature fusion processing, extrude in the process with the spinning operation and can protect polymer.Phenolic antioxidant can also be protected the fiber of polymer beads and generation when storing and finally use.
Unexpectedly, found and can replace phenolic antioxidant that this stabiliser system is the binary composition of the ternary composition of the bulky amine selected, selected azanol and selected phosphite ester or selected bulky amine and selected azanol with stabiliser system of the present invention.Described system can provide the obtainable stability of stabiliser system with phenolic antioxidant component that surpasses with conventional, when stable polypropylene fibre is exposed to the smoked environment that fades of gas, is in the nitrogen-containing oxide atmosphere time, can not produce the variable color relevant with phenolic antioxidant.
