Abstract
The invention provides a rubber modifying method being capable of maintaining durable elasticity of rubber under alkaline conditions and relates to the field of rubber additives. The method includes the steps of: adding an additive to paraffin oil so as to disperse the additive uniformly in the paraffin oil to prepare a modifying additive, wherein the mass of the additive is 82.5% by mass of the paraffin oil; adding the modifying additive to a rubber raw material according to addition quantity of 1.25% by mass of rubber, and performing plastication, mixing, and vulcanization moulding to obtain the rubber product having durable elasticity under alkaline conditions. The additive is prepared by blending the raw materials including, by weight, 0.1 parts of erbium oxide, 2.1 parts of sodium carboxymethylcellulose, 5.2 parts of mica powder, and 1.3 parts of polyacrylate. The additive is used with the paraffin oil as a carrier and has excellent dispersibility. The rubber product is prepared by adding the additive to the rubber raw material according to certain ratio and performing the plastication, mixing, vulcanization and moulding, so that the rubber has durable elasticity under alkaline conditions.
Description
Technical field
The present invention relates to rubber additive field, more particularly, to one kind can keep rubber to have lasting bullet in the basic conditions
The Rubber modification method of property.
Background technology
Material is material base and the guide of social production and technological progress, the macromolecular material that eighties of last century grows up
Industry bring huge material progress to human society, rubber as the important component part of macromolecular material, in tire system
Make aspect and there is the irreplaceable specific function of other materials, become indispensable important thing in national economy and daily life
Matter.With the development of modern science and technology, to aspects such as the elasticity of rubber for tire, abrasion resistance, alkali resistance, alkali resistance, aging resistance
Require more and more higher, and traditional rubber additive is limited to its mechanical property raising, present technology can not meet this
Plant and require, be badly in need of the new rubber additive of exploitation, improve the serviceability of rubber.
Content of the invention
It is an object of the invention to provide a kind of modified rubber keeping rubber to have persistently elasticity in the basic conditions
Method, to solve above-mentioned technical problem.
The technical problem to be solved employs the following technical solutions to realize:
A kind of keep rubber have in the basic conditions persistently elasticity Rubber modification method it is characterised in that: by such as
The raw material mixture of lower weight portion forms:
0.1 part of Erbia, 2.1 parts of sodium carboxymethyl cellulose, 5.2 parts of mica powder, 1.3 parts of polyacrylate.
Preferably, also containing 0.23 part of nano aluminium oxide in raw material.
Preferably, the granularity of described mica powder is 2-15 micron.
A kind of keep rubber have in the basic conditions persistently elasticity Rubber modification method it is characterised in that:
Additive is added in paraffin oil, makes additive dispersed in paraffin oil, obtain property-modifying additive, additive
Quality be paraffin oil quality 82.5%；
Property-modifying additive is added in rubber raw materials, the addition of additive is the 1.25% of rubber quality, is moulded
Refining, mixing, sulfidization molding, obtain final product the rubber product can in the basic conditions with persistently elasticity；
Additive therefor is formed by the raw material mixture of following weight portion: 0.1 part of Erbia, 2.1 parts of sodium carboxymethyl cellulose,

The invention has the beneficial effects as follows:
The additive of the present invention, with paraffin oil as carrier during use, has preferable dispersibility, adds according to certain ratio
Enter in rubber raw materials, through over-mastication, mixing, sulfidization molding, the rubber product obtaining, can have lasting bullet in the basic conditions
Property,
Erbia, sodium carboxymethyl cellulose, mica powder, polyacrylate,
Mica powder and polyacrylate synergism, make rubber be very easy to polymerization, and it contributes to sending out in the basic conditions
Wave the performance of sodium carboxymethyl cellulose and Erbia, mechanical property, ageing resistace and the alkali resistance of rubber can be improved, so that
Rubber has lasting elasticity in the basic conditions.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the present invention realizes are easy to understand, tie below
Close specific embodiment, the present invention is expanded on further, but following embodiment is only the preferred embodiments of the present invention, and not all.
Based on the embodiment in embodiment, those skilled in the art are obtained other real on the premise of not making creative work
Apply example, broadly fall into protection scope of the present invention.
A kind of Rubber modification method keeping rubber to have persistently elasticity in the basic conditions, former by following weight portion

1.3 parts, 0.23 part of nano aluminium oxide,
Rubber can be kept to have the Rubber modification method Rubber modification method of persistently elasticity in the basic conditions,
(1) additive is added in paraffin oil, make additive dispersed in paraffin oil, obtain property-modifying additive, add
Plus the quality of agent is the 82.5% of paraffin oil quality；
(2) property-modifying additive is added in rubber raw materials, the addition of additive is the 1.25% of rubber quality, carries out
Plasticate, knead, sulfidization molding, obtain final product can have in the basic conditions persistently elasticity rubber product.
According to national standard, performance test is carried out to the rubber product prepared, result is as shown in the table:
Ultimate principle, principal character and the advantages of the present invention of the present invention have been shown and described above.The technology of the industry
The only present invention it should be appreciated that the present invention is not restricted to the described embodiments, described in above-described embodiment and description for the personnel
