Abstract
The invention proposes an aging-resistant rubber, wherein the composition comprises the following components in parts by weight of 100 parts of fluororubber, 15 parts of barium sulfate, 20 parts of calcium silicate, 6 parts of magnesium oxide, 0.8 parts of carbon black N774, 0.8 parts of palm wax, 0.7 parts of WS280, and 0-1.5 parts of calcium hydroxide. The rubber prepared from the composition, a preparation method and a heat-resisting evaluation method are also provided. The aging-resistant performance of the rubber is the best when the usage of the calcium hydroxide is 1.0 part.
Description
Technical field
The present invention relates to chemical field, particularly a kind of ageing-resistant rubber.
Background technology
Along with developing rapidly of Vehicle Industry, pursuit to high speed and security is more and more higher, as automotive rubber products, require thermotolerance and the necessary corresponding raising of sealing property of its elastomeric material, because the high speed of vehicle, thereby the part temperatures around the engine is raise gradually, therefore improve engine and the thermotolerance of rubber item is very necessary on every side.
Summary of the invention
The present invention proposes a kind of ageing-resistant rubber, has solved in the prior art high temperature to the destruction problem of rubber packing material.
Technical scheme of the present invention is achieved in that ageing-resistant rubber, contains following material and weight part: 100 parts of viton, 15 parts in barium sulfate, 20 parts of Calucium Silicate powder, 6 parts in magnesium oxide, 6 parts of red iron oxides, 0.8 part of carbon black N774,0.8 part of palm wax, 0.7 part of WS280, calcium hydroxide 0-1.5 part.
Preparation method of the present invention is identical with existing method for preparing rubber.
The present invention is by adding the calcium hydroxide of different amounts, the ageing-resistant performance of research viton.
The invention has the beneficial effects as follows:
(1) the present invention has obtained a kind of ageing-resistant rubber, can be used in the motor car engine the inside, plays sealing function, reduces hot environment to the destruction of rubber;
(2) the present invention has obtained a kind of resistant to elevated temperatures sealing-ring, can be used in the sealing station of automobile.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the synoptic diagram of experimental installation of the present invention.
Embodiment
The present invention by adding the calcium hydroxide of different content, obtains a kind of ageing-resistant rubber through extensive and deep research, then carries out the high temperature experiment, thereby finishes the present invention.Experimental installation of the present invention comprises as shown in Figure 1: rubber mixing mill 10, vulcanizing press 20, rubber slitter 30, ageing-resistant experiment 40.
Viton
(English name: Fluororubber) main Types has three kinds to viton: fluorine carbon, fluorine silicon and fluoroalkyl phosphonitrile.Main production is fluorine carbon at present, and the fluorine carbon viton mainly comprises: vinylidene and chlorotrifluoroethylene (23 glue); The multipolymer of vinylidene, R 1216 (26 glue); The terpolymer of vinylidene, R 1216 and tetrafluoroethylene (246 glue); Tetrafluoroethylene and propylene (4 third viton).
In order to reach ageing-resistant performance of the present invention, the present invention has adopted Du Pont's viton.
Preferably, described Du Pont viton, the trade mark are VTR7576, can life-time service under 200 ℃ of environment; Under 250 ℃ of environment, can short-term use.
Calcium hydroxide
Calcium hydroxide is a kind of white powder solid.Have another name called slaked lime.Calcium hydroxide has the general character of alkali, is a kind of highly basic.Calcium＞sodium), but because the solubleness of calcium hydroxide is more much smaller than sodium hydroxide, so the corrodibility of aqua calcis and alkalescence are less than sodium hydroxide the alkalescence of calcium hydroxide is than the strong (movable metallic: of sodium hydroxide.These character have determined that calcium hydroxide is widely used.
Preferably, described calcium hydroxide adopts the lime slaking method: with Wingdale after being sintered into calcium oxide, digest with the ratio of water in 1: 3 through selected, generating the calcium hydroxide feed liquid removes the gred through purification separation, again through centrifuge dehydration, in 150～300 ℃ of lower dryings, screening (more than 120 orders) is the calcium hydroxide finished product again.
Ageing-resistant component
Ageing-resistant component of the present invention comprises:
Below in conjunction with specific embodiment, further set forth the present invention.The experimental technique of unreceipted actual conditions in the following example is measured according to national standard usually.If there is not corresponding national standard, then carry out according to general international standard, normal condition or according to the condition that manufacturer advises.Unless otherwise indicated, otherwise all umbers are weight part, and all per-cents are weight percentage, and described polymericular weight is number-average molecular weight.
Unless otherwise defined or explanation, same meanings of being familiar with of all specialties used herein and scientific words and those skilled in the art.Any method similar or impartial to described content and material all can be applicable in the inventive method in addition.
Comparative Examples:
Select 0,0.5,1,1.5 part calcium hydroxide
100 parts of viton, 15 parts in barium sulfate, 20 parts of Calucium Silicate powder, 6 parts in magnesium oxide, 6 parts of red iron oxides, carbon black N7740.8 part, 0.8 part of palm wax, WS2800.7 part, calcium hydroxide 0-1.5 part, what play ageing-resistant effect mainly is viton.
Processing condition are as follows:
Fluorine glue VTR7576 plasticates in two roller mills, and the roller temperature behind the bag roller, adds magnesium oxide, calcium hydroxide, palm wax, WS280, red iron oxide, carbon black N774, barium sulfate, Calucium Silicate powder below 50 ℃ successively, beats triangle bag thin-pass and descends afterwards sheet six times.Before mixing, must keep roller clean, not have contaminated.Use vulcanizing press to carry out one step cure, press vulcanization: 170 ℃ * sulfurizing time of one step cure; Oven heat sulfuration: 200 ℃ * 4h of post vulcanization.Fluorine glue VTR7576 cross-linked rubber is pressed into the dumbbell shape test piece at sheet-punching machine carries out ageing-resistant experiment.
Ageing-resistant experimentation: the dumbbell shape sample is placed on the 70h that wear out under 200 ℃ in the DHG-9075A electric heating constant-temperature blowing drying box, takes out its hardness of test, carry out tensile strength and elongation at break experiment and observe its destruction pattern, then calculated performance conservation rate.
C＝b/a×100％
C-property retention rate; Tensile strength and elongation at break before a-is aging;
Tensile strength and elongation at break after b-is aging
Performance and the ageing-resistant performance of this glue are as shown in the table:
As can be seen from the above table, when the calcium hydroxide consumption was 1.0 parts, the rubber ageing-resistant performance that makes was optimum.
