Description
Technical field
The present invention relates to a kind of rubber antioxidant.
Background technology
Rubber is during processing, storing and use, due to the combined influence by internal and external factor, it may appear that
Deliquescing, tacky, harden, chap, embrittlement, speckle, the catabiosis such as mouldy, loss of gloss, color change,
Rubber antioxidant is a kind of material that can prevent or delay ageing of rubber.Antioxidant D is the thirties in 20th century
Begin to an old brand amines antioxidants of production application.Owing to it can protective hot oxygen aging and subduing effectively
It is aging that fatigue causes, and cheap, and therefore in rubber industry, consumption is the biggest.But there is toxicity in it,
And bin stability is poor, exposes and in atmosphere and grey black will be become from white under daylight.At rubber product
During use, especially under the effect of light and heat, transparent rubber can become dark, simultaneously dirty by migrating
The material that dye is in contact with it.The chance phototropic of antioxidant D goes bad and oxidation deterioration, and tracing it to its cause is due to anti-
The chemical change that impurity in old agent causes.The most therefore, the U.S., Japan, West Europe before and after 1970 the most
Start significantly to compress the yield of D, D is modified simultaneously.
Present invention aim to provide a kind of modified rubber antioxidant D, to reduce its toxicity, mobility obtains
To effectively reducing, and impurity content therein effectively reduces.
Summary of the invention
Present invention aim to provide the modified rubber antioxidant D of a kind of low toxicity, low migration, low impurity
The technical scheme realizing the object of the invention is:
A kind of Novel rubber antioxidant, it is characterised in that: it is 20%～60% p-phthalic acid gold by mass ratio
Belonging to salt and be dried 30min in vacuum environment at 100 DEG C, be cooled to room temperature under vacuum environment, adding mass ratio is
The silane coupler of 10%～40%, mix homogeneously, stop activation 10～20min, by mass ratio be
20%～60% antioxidant D is dissolved in acetone soln, adds the mixture activated, and reacts 1～5h,
Finally filtering, wash, be dried, acetone soln evaporimeter carries out concentrating recycling.
As preferably, described metal salt of terephthalic acid is p-phthalic acid calcium, p-phthalic acid magnesium, right
In phthalic acid zinc, potassium terephthalate, para-phthalic sodium, p-phthalic acid barium, p-phthalic acid aluminum
One or more.
As preferably, described silane coupler is double-(the silica-based propyl group of γ-triethoxy) tetrasulfide
(Si69), double (the silica-based propyl group of triethoxy) disulphide (Si75), gamma-mercaptopropyltriethoxysilane
(KH-580), gamma-aminopropyl-triethoxy-silane (KH-550), γ-(2,3-epoxy the third oxygen) propyl group three
One or more in methoxy silane (KH-560).
The rubber anti-ageing agent of gained of the present invention is compared with traditional antioxidant D, and its toxicity reduces, and impurity contains
Measuring low, mobility is low.And its preparation technology is simple, low price, it is possible to decrease cost, improves product quality
And economic benefit.The present invention can effectively reduce age resistor and migrate the environmental pollution produced, and divides in elastomeric material
Dissipating property good, practical function is high.
