Abstract
The polyolefine anti-ageing mother material includes polyolefine resin and assistant, its characteristic is that it uses di(2,2,6,6-tetramethyl piperidine) sebacate as main photo-stabilizer, phosphonous acid tri(2,4-di-tert-butyl phenyl) ester as main oxidation preventive stabilizer. Di(3,5-di-tert-butyl-4-hydroxyl benzyl monoethyl phosphate) Ni, rutile type titanium dioxide, and 1,3,5-(3,5-di-tert-butyl-4-hydroxyl benzyl) triazine-2,4,6-(1H,3H,5H) triketon may be added. The polyolefine products have such functions as anti-photo and oxidation ageing, wter-resistance and color stabilization.
Description
The present invention is the functional masterbatch of a kind of polyolefine, is a kind of mixture, is specially adapted to the forming process of plastics, has improved anti-light, the oxygen aging performance of polyolefin resin and plastics.
At present, be used for polyolefinic photostabilizer, antioxidant stabilizer is a lot, also has unifunctional light to stablize masterbatch, as TINUVIN MB218 etc.In anti-aging polyolefin articles manufacturing processed, as stablizing masterbatch with unifunctional light, not only cost height, and light stabilising effect is not best, can not satisfy simultaneously the fast light stable and antioxygen of plastics and stablize dual requirement, as packaging plastic braid and engineering earth worker synthetic materials etc.; In addition, directly mix use with polyolefin resin with photostabilizer and antioxidant stabilizer, poor dispersion not only, and tend to because of interaction produces negative synergism, light, oxygen stabilizer performance are all descended, do not reach the anti ageing property requirement.
The objective of the invention is to: a kind of polyolefine anti-aging mother material is provided, makes it fast light, dual stabilization of oxygen be arranged the polyolefin resin in processing and the use.
The present invention seeks to realize like this, it comprises polyolefin resin, processing aid, select for use two (2,2,6,6-tetramethyl-piperidyl) sebate to make main photostabilizer, select tricresyl phosphite (2,4-di-tert-butyl-phenyl) ester as main antioxidant stabilizer, its main formula is (by weight):
Polyolefine 70～95
Processing aid 0.05～2.5
Two (2,2,6,6-tetramethyl-piperidyl) sebate 5～20
Tricresyl phosphite (2,4-di-tert-butyl-phenyl) ester 1～10
In the main formula system, can be added with photostabilizer two (3,5-di-tert-butyl-4-hydroxyl benzyl monoethyl phosphate) nickel and rutile titanium dioxide, antioxidant stabilizer 1,3,5-(3,5-di-tert-butyl-4-hydroxyl benzyl) guanamine, 4,6-(1H, 3H, 5H) triketone, add-on is (by weight):
Two (3,5-di-tert-butyl-4-hydroxyl benzyl monoethyl phosphate) nickel≤10
Rutile titanium dioxide≤20
1,3,5-(3,5-di-tert-butyl-4-hydroxyl benzyl) guanamine, 4,6-(1H, 3H, 5H) triketone≤10;
Also can in the main formula system, add photostabilizer two (3,5-di-tert-butyl-4-hydroxyl benzyl monoethyl phosphate) nickel and antioxidant stabilizer 1,3,5-(3,5 di-tert-butyl-4-hydroxyl benzyls) guanamine, 4,6-(1H, 3H, 5H) triketone, add-on is (by weight):
Two (3,5-di-tert-butyl-4-hydroxyl benzyl monoethyl phosphate) nickel≤10
1,3,5(3,5-di-tert-butyl-4-hydroxyl benzyl) guanamine, 4,6-(1H, 3H, 5H) triketone≤10
Perhaps only in main formula, add antioxidant stabilizer 1,3,5-(3,5-di-tert-butyl-4-hydroxyl benzyl) guanamine, 4,6-(1H, 3H, 5H) ketone, add-on is (by weight) :≤10;
Also can in the main formula system, add the photostabilizer rutile titanium dioxide in addition.Add-on is (by weight) :≤20
Physical data report oxidation inhibitor 1,3,5(3,5-di-tert-butyl-4-hydroxyl benzyl) guanamine, 4,6-(1H, 3H, 5H) sebate has negative synergism to triketone to two (2,2,6,6-tetramethyl-piperidyl), but this negative synergism is eliminated in this formula system.The not water-fast extractibility of this formula system two to improving (2,2,6,6-tetramethyl-piperidyl) sebate has been made outstanding contributions.The present invention is mixed according to the order of sequence and get through mixing, cooling, granulation in the plastic extruding pelletization machine by formula system.The made plastics of product of the present invention that in polyethylene or acrylic resin, add an amount of parts by weight, according to GB 9344 and ISO 4892 standards, artificial accelerated aging 200 hours, the polyethylene products strength retention can be greater than 95%, and the polypropylene articles strength retention can be greater than 90%; Press GB 3681 and ISO 4607 standards, natural climate exposes to the open air, and when the product strength conservation rate equaled 50%, polyolefin articles adds product of the present invention can be greater than 20 times than not adding product exposure duration of the present invention (promptly using the life-span).
Superiority of the present utility model is: polyolefin resin or goods in processing and the use are had fast light, the dual stabilization of oxygen, and easy to use, good processing stability, and have water-fast extractibility good, to the characteristics of pigment color and luster good stability, the present invention is further elaborated below by example.
