Abstract
The present invention provides an EVA composition with the functions of deodorization and odor prevention and a formula thereof. The composition at least contains 100PHR(part per hundred resin) of EVA(Ethylene Vinyl Acetate Co-polymer), 15 to 50 PHR of CaCO3(calcium oxide), 1 to 10PHR of ZnO2, 1 to 5PHR of peroxide, 0.2 to 5PHR of antioxidant and 0.5 to 2PHR of fatty acid. Various deodorants compatible with EVA are invented under the condition that the quality of plastic EVR products is not affected, and thus, the EVA products have the characteristics of wear resistance and shock resistance and have the functions of deodorization and odor prevention.
Description
The present invention relates to a kind of prescription with plastic cement of deodorizing and deodorization performance, be the ethylene vinyl acetate copolymer composition (being designated hereinafter simply as the EVA composition) of a kind of deodorizing and deodorization, refer to a kind of EVA composition and prescription thereof that contains antioxidant and superoxide especially.
Existing general plastic cement; especially product such as ethylene vinyl acetate copolymer plastic cement or ethylene vinyl acetate copolymer foam; after using, can stink usually; especially the part such as the gloves that contact with human body of these plastic cement products; sole; slippers etc. often use the peculiar smell that is sent to make us being difficult to stand; in order to address this problem; people once adopted the method that adds or spray aromatoising substance on the top layer of this series products; but this method also fails really to eliminate or prevent stink; because the validity of aromatoising substance is limited, in case still exist at the ineffective back of the aromatoising substance on its top layer stink.
The reason that various plasthetics produce stinks is a lot, as the kind of additive and quantity what or all may become the factor that produces stink because of the thermal response that applied in the machine-shaping or environment for use etc.And the stink kind that produces in the process of plastic cement production is also a lot, as the stink of nitrogen compound, and the stink of sulfide, the stink of mercaptan, butterfat is smelly, putrefactive odor corrosion stink or the like; The mixture of plasticizer contains in impure composition or its decomposition product and also can produce peculiar smell in addition; The stablizer that is added in the plastic cement, lubricant, weighting agent and colorant etc. also may produce stink, after the formed product, employed Oil solvent when on product, printing, residual composition also may produce stink.The stink that a variety of causes produces is all very big to the quality influence of product, gives the human consumer also with very big trouble.
Purpose of the present invention is exactly in order to solve the problem of above-mentioned prior art, to have invented a kind of deodorization and the vinyl acetate copolymerized composition of deodorization sex ethylene at the various factors that may produce stink.
Formation of the present invention comprises 100 parts of EVA at least, 15～50 weight part lime carbonate, 0-10 weight part Cellmic C 121,0～10 weight part frothing aid, 1～5 weight part superoxide, 0.5～2 weight part lipid acid and 0.2～5 weight part antioxidant.
Deodorizing composition used in the present invention comprises a kind of superoxide at least, this superoxide can be divided into inorganic peroxide and organo-peroxide two big classes again, described inorganic peroxide is sodium borohydride, lithium borohydride, Potassium Persulphate or Sodium peroxoborate or the like, is applicable to that the kind of organo-peroxide of the present invention is:
(1) hydroperoxide (hydroperoxide) are as tert-butyl hydroperoxide
(tertbutyl hydroperoxide), cumene hydroperoxide
(isopropyl?benzene?hydroperoxide)。
(2) acyl peroxide (Acyl peroxide) is as the diacetyl superoxide
(Diacetyl peroxide), two propionyl superoxide (Dipropionyl
Peroxide), dibenzoyl superoxide (Dibenzoyl peroxide)
Two (2-toluyl) superoxide (Bis (2-methylbenzoyl)
peroxide)。
