Abstract
The invention relates to a method for preparing an antioxidant for plastic or rubber processing. The method comprises the following steps of: mixing dibasic alcohol ether, o-hydroxybenzoic acid and a non-acidic catalyst Cat102, reacting at the temperature of 150 to 210 DEG C for 4 to 5 hours with stirring, adding long-chain fatty acid, continuously reacting for 4 to 5 hours with stirring, cooling to 110 DEG C, and filtering to obtain a hindered phenol compound antioxidant for plastic or rubber processing, which has multiple functional groups and contains hydroxyl or phenol, ester, ether and a long carbon chain. The product prepared by the method has the functions of resisting oxidation, removing free radicals, improving intermolecular friction force and preventing the color of a plastic or rubber product from being changed, and is low in cost, the production process is simple and reasonable and accords with the national environmental protection policy, the application range is wide, and three wastes (waste gas, waste water and waste residues) are not discharged from a system; and in addition, the production process is short, the utilization rate of equipment is high, and the product is stable in quality.
Description
Technical field
The present invention relates to a kind of preparation method of processing aid, especially relate to the preparation method of oxidation inhibitor for a kind of plastics or Rubber processing.
Background technology
When producing the macromolecular materials such as plastics, rubber, need to add some inorganic fillers as light, water-ground limestone, talcum powder, wollastonite powder etc. at present.But inorganics and macromolecular material are difficult for mixing and cannot, in conjunction with evenly, being commonly called as consistency poor as plastics or rubber.Traditional improvement method is to add the compound of some coupling agents and so on, and as silicane, titanate ester and aluminate, long-chain fat acids etc., its shortcoming is as follows:
(1) few, the function singleness of kind, effect are limited; (2) complex manufacturing, energy consumption greatly, easily produce the three wastes (waste water, waste residue, waste gas etc.); (3) need to use many organic solvents, particularly inflammable explosive article, production requirement is higher; (4) product cost is high, is difficult for the marketization.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide the preparation method of oxidation inhibitor for a kind of production technique is simple, action effect is good plastics or Rubber processing.
For achieving the above object, the present invention is achieved by the following technical solutions:
The preparation method of oxidation inhibitor for a kind of plastics or Rubber processing, it is characterized in that, first glycol ether, salicylic acid and non-acidic catalyst Cat102 are mixed, and at the temperature of 150～210 ℃, stirring reaction 4～5 hours, and then add longer chain fatty acid to continue stirring reaction after 4～5 hours, be cooled to and after 110 ℃, filter polyfunctional group hindered phenol compound plastics or the Rubber processing oxidation inhibitor that obtains containing hydroxyl or phenolic group, ester group, ether, long carbochain.
Described non-acidic catalyst Cat102 comprises stannic oxide and borax, and described stannic oxide and the mass ratio of borax are 1～3:1.
Described longer chain fatty acid is stearic acid.
And the order number of the filter screen that described filtration adopts is 200 orders.
The invention has the beneficial effects as follows: the plastics that are numbered P300 prepared by method of the present invention or Rubber processing with oxidation inhibitor have anti-oxidant, remove the free radical that produces in plastic working and the rubber item course of processing, improve frictional force, the non-discoloring function of protection goods color between molecule; particularly especially obvious in light plastics casing rubber item; and with low cost; production technique advantages of simple; applied range; outside system, do not discharge the three wastes, meet national environment protection and environmental friendliness policy.In addition, the technological process of production of the present invention is short, and plant factor is high, constant product quality.

First salicylic acid, binary ether alcohol and non-acidic catalyst Cat102 are dropped in reactor, and be warming up to 150～210 ℃, stirring reaction, 4 hours, and then to adding in reactor stearic acid to continue stirring reaction after 5 hours, now do not have steam out, be synthetic end point, then be cooled to 110 ℃ of left and right, cross 200 mesh filter screens, filter and obtain containing hydroxyl or phenolic group, ester group, ether, grow the polyfunctional group hindered phenol compound plastics of carbochain or oxidation inhibitor (numbering P300) for Rubber processing.
Wherein, described non-acidic catalyst Cat102 comprises stannic oxide and borax, and described stannic oxide and the mass ratio of borax are 1～3:1.In the present embodiment, the quality of described stannic oxide is 2kg, and the quality of described borax is also 2kg, can certainly be all ratios within the scope of 1～3:1 such as 2:1 or 3:1.
Chemical equation following (carrying out in two steps):
Above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
