Abstract
The present invention is recipe of food package level ethylene-propylene rubber. The food package level ethylene-propylene rubber consists of ethylene-propylene rubber 54-60 wt%, carbon black 22-28 wt%, plasticizer 6-10 wt%, metal compound 4-6 wt%, antiager 0.5-5 wt% and peroxide 4.5-6 wt%. The food package level ethylene-propylene rubber reaches the BS6920 standard and has, especially, dissolved and leached metal content far lower than the maximum allowed value. The food package level ethylene-propylene rubber may be used for some special uses.
Description
Technical field
The invention belongs to the rubber technology field, particularly be Recipe of food package level ethylene-propylene rubber.
Background technology
Coventional type ethylene-propylene rubber(EPR) exists the defective of prescription purposes diversification.Needed in European Union three states (Great Britain and France's moral) water works at that time with control dish valve, sample is provided as coventional type second third, Britain WRAS company gives the complete detection conclusion: significantly improve microorganism growth speed in the water when this product valve seat rubber seal is touched water by the rubber valve seat sealing-ring 7-8 week, the MDOD of product (average dissolved oxygen difference) dissolved oxygen amount reduces manyly more, and the MDOD value is just big more.The MDOD value is defective greater than the 2.9mg-l product.Detect seven work at cytotoxin and say, obtain chemical examination and the cytotoxin reflection occurs.Detecting the molten filter of assessment product metal exceeds standard more than half for 13 kinds.This thing occurs in 2002, though manufactured experimently repeatedly sample several times is provided in back two years 03,04 year, its result is still not good.In this background, launch to grind visiting abroad in the novel ethylene-propylene rubber(EPR), finally adopt the nano inorganic element formula to succeed.The product Britain that provides
WRAS company gives the tap water regulation and instructs the influence specification sheets of BS6920 detection to water quality.
Detect specification:
BS6920 comprises five different tests:
| Sequence number | Content measurement | Period |
| 1 | The taste of water | 14 working dayss |
| 2 | The appearance of water | 14 working dayss |
| 3 | Microorganism growth | 7 weeks |
| 4 | The cytotoxin activity | 7 working dayss |
| 5 | Extract metal | 4 weeks |
1, the taste of water: extract the sample diluent.There is not the aroma and flavor Passing Criteria.
2, the appearance of water: extract all coincidence detection standards of mean value that last water sample, its color and muddy degree calculate.
3, microorganism growth: just can indicate it than the numerical value of this positive reference system (paraffin) more than the report of this product of 0.5mg-l with reference to MDOD (on average molten oxygen difference) value and have antibacterial/germicidal action.
4, cytotoxin effect: extract two acellular toxin reflections of sample tool.
5, extract metal: neither surpass " maximum acceptable concentration " of the concentration of the specified metal that therefrom extracts then made the conformance with standard opinion.
The U.S. sanitary medicine NSFLTD of association also gives technical approval to this product simultaneously.Coventional type ethylene-propylene rubber(EPR) and novel RBMTLDFM ethylene-propylene rubber(EPR) are tested aspect five in sum.Novel ethylene-propylene rubber(EPR) formulation product has reached the technical requirements standard of aspects such as world market tap water, medicine, food, health.But detect in the explanation in U.S. WRAS company, the 5th lixiviation metal content is though metal concentration illustrates measured parameter value above " maximum acceptable concentration value " in the test, near stagnation point.We must give enough attention to this.RBMTLDFM ethylene-propylene rubber(EPR) technical formula is primarily aimed at procreation, the bacteriotoxin activity of drinking-water, medicine, food sanitation inhibition microorganism, holds the control of filter metal and makes all many-sides such as drinking-water, food sanitation, medicine, safeguards the primary condition of human survival.
Summary of the invention
The invention provides a kind of ethylene-propylene rubber(EPR) prescription, it not only can reach BS6920 and comprise five different testing standards, and at the 5th lixiviation metal content, metal concentration is far smaller than " maximum acceptable concentration value " in the test.
The component of ethylene-propylene rubber(EPR) prescription of the present invention and weight divide content as follows in vain:
Ethylene-propylene rubber(EPR) 54～60
Carbon black 20～28
Softening agent 6～10
Metallic compound 4～6
Anti-aging agent 0.5～5
Superoxide 4.5～6
Softening agent of the present invention comprises vegetables oil, preferred pure soya-bean oil, peanut oil or rapeseed oil;
Carbon black can be carbon black N550, carbon black N330, carbon black N660;
Metallic compound of the present invention comprises metal oxide, preferred zinc oxide, magnesium oxide;
Anti-aging agent of the present invention comprises antioxidant 264, anti-aging agent RD, anti-aging agent 124;
Superoxide of the present invention comprises dicumyl peroxide, tert-butyl peroxy sec.-propyl;
Antibacterial, little poison of the present invention, low lixiviation metal food package level ethylene-propylene rubber prescription are the multipolymer of ethene, propylene or the terpolymer that ethene, propylene and a small amount of dienes monomer copolymerization form.Because of ethylene-propylene rubber(EPR) proportion less than a large amount of oil-filled and fill carbon black.And adding both sexes zinc oxide and superoxide.
Processing method of the present invention is as follows:
135 ℃ ± 5 ℃ of rubber unvulcanizate controlled temperature.Sulfuration controlled temperature: 170 ℃ ± 5 ℃.In synthetic, want strict control free monomer and catalyst residual content.Participate in the various starting material of synthetic in a word and be necessary for the non-polluting base.
Antibacterial, little poison of the present invention, low lixiviation metal food package level ethylene-propylene rubber prescription can supply some special industries application both at home and abroad, make to suppress its Application Areas of the low lixiviation metal ethylene-propylene rubber(EPR) product expansion of bacteriotoxin.
