Abstract
The invention discloses a silicone rubber addictive, which comprises polyorganometallosiloxane, a cross-linking agent, a gas phase white carbon black, and a heat-resistant addictive. The addictive overcomes the shortages of bad high temperature resistant and anti-aging performances existing in conventional silicone rubbers; hydroxyl silicone oil and methyl ethyl silicone oil are added, thus the tearing resistant performance of silicone rubber is strengthened; the novel silicone rubber which is produced by using the silicone rubber additive has a better heat resistant property than that of the original silicone rubber; and the additive has the advantages of little using amount and user-friendliness.
Description
Technical field
The present invention relates to silicon rubber technical field, particularly relate to a kind of silicon rubber additive.
Background technology
Silicon rubber is a kind of good specialty elastomer, it has good thermotolerance, low temperature resistant, insulativity, antidetonation, resistance to compression, wear-resistant and good biological nature, make it have range of application widely, such as building, communications and transportation, electronic apparatus, chemical industry, biomaterial and present aerospace material etc.Silicon rubber can be at-65 ℃～200 ℃ life-time service now, but along with scientific and technological development, its thermotolerance is had higher requirement, and present aeronautical and space technology requires silicon rubber life-time service at higher temperature, the resistance to elevated temperatures that further improves silicon rubber has very large meaning; In addition, in the situation that thermotolerance improves, the tear strength of silicon rubber also needs further perfect.Therefore need a kind of new silicon rubber additive to improve thermotolerance and the tear strength of silicon rubber.
Summary of the invention
Object of the present invention is exactly to provide a kind of silicon rubber additive for the defect of above-mentioned existence.There is the poor defect of heat resistant in the ordinary silicon rubber that the present invention has overcome prior art, the tear strength that the hydroxy silicon oil adding and methylethyl silicone oil have increased silicon rubber, add the novel material effect of preparing in silicon rubber to better than original silicon rubber heat-resisting, addition is little, easy to use.
A kind of silicon rubber additive technology scheme of the present invention is to comprise polyorganometallosiloxane, linking agent, gas-phase silica and heat-resisting additive.
Linking agent is hydroxy silicon oil and methylethyl silicone oil.
Contain following composition by weight: 100 parts of polyorganometallosiloxanes, 20～50 parts of gas-phase silicas, 1～5 part of methylethyl silicone oil, 1～5 part of hydroxy silicon oil, 1～10 part of heat-resisting additive.
Described heat-resisting additive is nano-stannic oxide.
Described gas-phase silica is that silanization is processed hydrophobic type gas-phase silica.
The metallic element of described polyorganometallosiloxane is titanium Ti.
Described polyorganometallosiloxane is pressed powder.
Described polyorganometallosiloxane granularity is 200-2000 order.
The add-on of this additive is that every 100 parts of raw-silastic continuouslies add additive 80-120 part by weight percentage.
Beneficial effect of the present invention is: silicon rubber additive of the present invention, the heat-resisting additive nano-stannic oxide of use belongs to rutile, has the features such as high-melting-point, Heat stability is good, corrosion-resistant, good mechanical stability.Hydroxy silicon oil and methylethyl silicone oil play Concentrative crosslinking in this composition, make it produce inhomogeneous Concentrative crosslinking, and the strong point that height of formation is crosslinked, has high tear strength.It is major function material that the present invention adopts solubility polyorganometallosiloxane, improve the intermiscibility (or dispersed) of additive in silicon rubber, thereby improve silicon rubber heat-resisting, through experimental verification, the product that silicon rubber additive of the present invention and raw-silastic continuously are prepared into can be used for a long time under the environment of 330-360 degree Celsius, and tear strength can reach 32.3KN/m.
