Abstract
The present invention provides a reasonable compatibility rubber antioxidant formed by compounding one or several kinds of raw materials of styrenated phenol, N-isopropyl-N'-phenyl-p-phenylene diamine, dioctyl phthalate and i-Inositol six phosphonolipid. The rubber antioxidant of the present invention has the advantages of good chemical stability in practical use, no decomposition at high temperature, water extraction resistance, good protection of ozone, heat, oxygen, flexural fatigue and ultra-violet ray, small dosage and good dispersivity; the dosage of the rubber antioxidant is 50% of the comprehensive dosage of general antioxidant, and the rubber antioxidant can be used with other antioxidants.
Description
The present invention relates to a kind of rubber antioxidant, belong to chemical composition.
Rubber antioxidant is as chemical assistant, become an independently subject, the rubber antioxidant of producing both at home and abroad can be divided into amine at present, phenols, phosphorous acid class and organic compounds containing sulfur four big classes, wherein with amine and phenols rubber antioxidant output and consumption maximum, as antioxidant A (N-phenyl-a-naphthylamine), antioxidant D (N-Phenyl beta naphthylamine) antioxidant SP (styrenated phenol), anti-aging agent RD (3,2,4-trimethylammonium-1,2-dihyaroquinoline polymer), antioxidant H (N, the N-diphenyl-para-phenylene diamine), antioxidant 4010 (N-encircles ethyl-N ＇-diphenyl-para-phenylene diamine), antioxidant 4010NA (N-sec.-propyl-N ＇-diphenyl-para-phenylene diamine) etc.Blended antioxidant has antioxidant A and 2, and the 4-tolylene diamine mixes; Antioxidant D, antioxidant H and 4,4 ＇-dimethoxy pentanoic mixes; Antioxidant H is mixed with anti-aging agent RD etc.Big (0.3-3 part) toxicity of these anti-aging agent usage quantitys and pollution are higher, and especially antioxidant D is because there is carcinogenic factor, and just ban use of the external eighties.
The object of the present invention is to provide a kind of rubber antioxidant of reasonable compatibility,, thereby reduce the use cost of pollution and producer with the consumption of minimizing anti-aging agent.
Technical scheme of the present invention is achieved in that and comprises styrenated phenol, N-sec.-propyl-N ＇-diphenyl-para-phenylene diamine, o-phthalic acid dibutyl ester by its composition of this rubber antioxidant wherein one or more raw materials and bios six phosphoric acid fat are compound formulated.
Described rubber antioxidant its better form comprise styrenated phenol, N-sec.-propyl-N ＇-diphenyl-para-phenylene diamine o-phthalic acid dibutyl ester, 3,2,4-trimethylammonium-1,2-dihyaroquinoline polymer, xylene formaldehyde resin, lime carbonate, wherein one or more raw materials and bios six phosphoric acid fat are compound formulated.
3,2,4-trimethylammonium-1,2-dihyaroquinoline polymer the component ratio of described rubber antioxidant is a styrenated phenol: N-sec.-propyl-N ＇-diphenyl-para-phenylene diamine: o-phthalic acid dibutyl ester:: xylene formaldehyde resin: lime carbonate: bios six phosphoric acid fat are 10-70: 5-50: 2-15: 10-50: 5-50: 30-100: 3-10.
3,2,4-trimethylammonium-1,2-dihyaroquinoline polymer the better ratio of the component of described rubber antioxidant is a styrenated phenol: N-sec.-propyl-N ＇-diphenyl-para-phenylene diamine: o-phthalic acid dibutyl ester:: xylene formaldehyde resin: lime carbonate: bios six phosphoric acid fat are 16: 40: 4: 30: 10: 30: 5.
Rubber antioxidant of the present invention has good chemical stability in actual applications, does not decompose under the high temperature, and water-fast extracting has favorable protection to ozone, heat, oxygen, flexing fatigue, ultraviolet ray; Consumption is little, be about 50% of the comprehensive consumption of general anti-aging agent, good dispersiveness can and be used with other anti-aging agent.Anti-aging agent of the present invention (trade name is an anti-aging agent 660) is as follows with the application performance contrast of commercially available anti-aging agent:
