The agglomerative composition that contains organic silicone elastomer

[0069] silicone elastomer can be joined that carrier fluid (above as component D) describes) in, form the agglomerative composition, perhaps at first can in independent reaction, prepare silicone elastomer, then it is joined in the carrier fluid, obtain gel.The feature of agglomerative composition of the present invention can be its hardness or solidness.The useful test that characterizes gel is those of GelatinManufacturers Institute of America recommendation, for example uses " TextureAnalyzer " (model TA.XT2, Stable Micro Systems, Inc., Godalming, Britain).The Texture Analyzer that employing has the probe of band 5.0kg load cell carries out compression testing to gel sample.Probe near gel surface, and continues to be compressed to the distance of 5.0mm in the gel with the speed of 0.5mm/sec, keeps for 1 second then before handling again.Texture Analyzer detects the resistance that stands at compression testing process middle probe.As the function of time, to the masterpiece figure that shows by load cell.

[0070] for purpose of the present invention, the hardness of silicone elastomer, gel and elastomer blend (SEB) is defined as the resistance that passes through the probe in detecting in " Texture Analyzer " in the compression testing process.Can use two data to characterize hardness: power 1, power during maximum compression point (entering the point of compression of 5.0mm in the gel surface) and area F-T: the integration of area-Li in 1 second process of maximum compression point place maintenance.Typically, amount to the average of 5 tests for each gel.

[0071] by firmly value (g) is divided by 101.97 (promptly 1 newton equals 101.97g power, based on the size of employed probe in this instrument), the data reduction that power 1 is obtained becomes newton (N).It is area F-T 1:2 that Texture Analyzer measures second performance reported, the g of unit power second.This is the area integral of power to the test period curve.This performance is the indication of gel network, because it shows the ability that keeps compression resistance force, this is relevant with elastomerics and gel.With g power second be that unit reports this numerical value, and by divided by 101.97, changing into ox second (SI units) with this numerical value (g of unit power second).

[0072] compressive hardness of silicon gel of the present invention is 200N/m at least ², perhaps 400N/m ², perhaps 600N/m ²

Measure the method for viscosity of silicone elastomer blend (SEB)

[0077] for feature class be similar to paste, putty, frost, gelatin or wax material, when using with the suitable Brookfield viscometer of being furnished with special T-rod type spindle, Brookfield Helipath ^TMIt is the viscosity/consistency measurement of unit that Stand will allow centipoise.

[0078] uses Brookfield Model RVD-II+ viscometer, measure the viscosity of silicone elastomer blend with Helipath stand (Brookfield Model D) and T-rod spindle (Brookfield Helipath Spindle Set).All these buy the Laboratories in Brookfield Engineering, and Inc. (11 CommerceBoulevard Middleboro, Massachusetts, USA).

[0079] sample size of requirement 100g in 4 ounces of cylindrical cans.Used following preparation section before measuring: at first by centrifugal, make the sample deaeration, the vacuum deaeration is 2 hours then.After deaeration, regulate minimum 4 hours of sample down at 25 ℃.In the center, with T-rod spindle location sample.According to the typical process of Helipath spindle, reading of data.

[0080] usually,, use spindle 93 (T-rod spindle C),, use spindle 95 (T-rod spindle E) for heavy-gravity sample relatively for heavy-gravity sample more not.Typical set value is 2.5rpm.Spindle speed maintains under the constant 2.5rpm and changes spindle, the sample that has remarkable viscosity with processing.

The measurement of silicone elastomer gels hardness

Use Texture analyzer (model TA.XT2, Stable Micro Systems, Inc., Godalming,, Britain) and, the hardness (or solidness) of sign silicone elastomer gels.Gelatin Manufacturers Institute of America recommends this test method as standard procedure.

For silicon gel and elastomer blend, the diameter of being made by DELRIN Derlin (Dupont) is that the cylindrical needle of 1/2 inch (1.27cm) is used for measuring.Use probe and following testing campaign, gel sample is carried out compression testing: probe, kept 1 second before handling near gel surface and continue to be compressed to the distance of 5.0mm in the gel then with the speed of 0.5mm/s again.Texture analyzer has the load cell of 5.0kg, detects the resistance that stands at compression testing process middle probe.As the function of time, to the masterpiece figure that demonstrates by load cell.

The hardness of silicone elastomer, gel and elastomer blend (SEB) be defined as in the compression testing process by probe in detecting to resistance.About hardness value, use two data: power 1, power during maximum compression point (point of compression of 5.0mm in gel surface) and area F-T: the integration of area-Li in 1 second process of maximum compression point place maintenance.Typically, amount to 5 tests, and report the mean value of 5 tests for each gel.

It is power (g of unit) that gel hardness is measured employed Texture analyzer, and this detects by transmodulator.About gel hardness, report two data: power 1, the power (g) of its pre-programmed depression fully in probe arrives gel sample when compression (or) record.The unit of power 1 reading is a g power.

Divided by 101.97 (promptly 1 newton equals 101.97g power, based on the size of employed probe in this instrument), will be converted into newton (N) by the value (g) of exerting oneself with regard to the numerical value of power 1 gained.For example, the numerical value of 6327g power is converted into 62.0N.

Second performance that Texture analyzer is reported is area F-T1:2, the g of unit power second.This is the area integral of power to the test period curve.This is the performance indication of gel network, because it shows the ability that keeps compression resistance force, this is relevant with elastomerics and gel.

With g power second be that unit reports this numerical value, and by with this numerical value (g of unit power second) divided by 101.97, change into ox second (SI of unit).For example, 33, the numerical value of 947g power second is 332.9N (SI units).
