Abstract
The invention relates to a silica gel composition, a preparation method of the silica gel composition and an insulation product made of the silica gel composition. The silica gel composition comprises the following components by weight: 50% of component A and 50% of component B, wherein the component A comprises following components: 65% of methyl vinyl silicone rubber, 25-28% of white carbon black, 0.1% of dibutyl phthalate and 5-9% of hydroxyl silicone oil; the component B comprises following components: aluminum hydroxide, aluminum oxide, magnesium hydroxide, magnesium oxide, quartz sand or mixture of any two or more. The preparation method of the silica gel composition comprises the steps of adding components of the component A to an internal mixer according to the proportion to mix; after a certain time, adding the component B, performing mixing uniformly to obtain the product. The silica gel composition has good insulation effect and can be widely applied in products with high requirement of insulation effect; and dielectric strength is 4000V.
Description
Technical field
The present invention relates to a kind of silica-gel composition, its preparation method and use the insulated product of its preparation.
Background technology
Along with the technical progress of silica gel industry, the quality of homemade silica-gel composition has increased significantly, and is current; Silica gel is very extensive in the application of China; Quantity and kind sustainable growth, Application Areas is constantly widened, and China has become the market of the tool potentiality of silica gel goods.But a lot of workplaces are higher to insulating requirements, and the silica gel that uses does not at present reach the ideal insulating requirements.
Summary of the invention
The purpose of this invention is to provide a kind of silica-gel composition, its preparation method and goods thereof, have the good insulation performance effect.
Silica-gel composition is characterized in that: be made up of 50% component A and 50% component B by weight percentage, wherein, component A is made up of following composition: methyl vinyl silicone rubber 65%-68%; WHITE CARBON BLACK 25%-28%; Two, two five 0.1%; Hydroxy silicon oil 5%-9%; Said B component is white lake or aluminum oxide or Marinco H or Natural manganese dioxide or silica sand or the above-mentioned mixing of two or more material arbitrarily.
Above-mentioned said WHITE CARBON BLACK is the silicon-dioxide that adopts vapor phase process to process.
The preparation method of aforesaid silica-gel composition is characterized in that: earlier drop into Banbury mixer to each composition of component A in proportion and carry out mixingly, add the mixing product that arrives of component B after for some time and evenly gets final product.
Use the insulated product of silica-gel composition preparation as described above.
Earlier drop into Banbury mixer to each composition of component A in proportion and carry out mixingly, add after for some time that component B is mixing evenly to get final product to product, be shaped to the insulated product of needs at last with rubber oil pressure vulcanizer.
Advantage of the present invention: have the good insulation performance effect, can be widely used in the demanding product of insulation effect, dielectric voltage withstand can reach 4000V.
Embodiment
Below in conjunction with embodiment the present invention is further described.
Silica-gel composition of the present invention is made up of 50% component A and 50% component B by weight percentage, and wherein, component A is made up of following composition: methyl vinyl silicone rubber 65%-68%; WHITE CARBON BLACK 25%-28%; Two, two five 0.1%; Hydroxy silicon oil 5%-9%; Said B component is a white lake.Said B component also can be aluminum oxide or Marinco H or Natural manganese dioxide or silica sand or the above-mentioned mixing of two or more material arbitrarily.Said WHITE CARBON BLACK is the silicon-dioxide that adopts vapor phase process to process.
The preparation method of silica-gel composition of the present invention is following: earlier drop into Banbury mixer to each composition of component A in proportion and carry out mixingly, add the mixing product that arrives of component B after for some time and evenly gets final product.As long as the not special restriction of mixing time is mixing even.Promptly can reach needed effect in common mixing 1-2.5 hour.
It is following that the present invention adopts above-mentioned silica-gel composition to prepare the method for insulated product: drop into Banbury mixer to each composition of component A in proportion earlier and carry out mixing; Add the mixing product that arrives of component B after for some time and evenly get final product, at last the silica-gel composition after mixing is shaped to the various insulated products that need with rubber oil pressure vulcanizer.
Said insulated product can be to be used for LED lamp body insulating insulation covering; For example in the structure of LED lamp commonly used; With the insulation covering that adopts silica-gel composition preparation of the present invention be arranged on aluminium base (aluminium base is provided with the circuit card of band LED lamp pearl) and the housing that is used to dispel the heat between, thereby make the dielectric voltage withstand of LED lamp can reach 4000V.
The present invention adopts methyl vinyl silicone rubber, trade mark MVQ1101.Employing is two, and two or five are linking agent, two, and two or five chemistry is by name: 2, and 5-dimethyl--2,5-bis(t-butylperoxy) hexane is the effective linking agent of vinylsiloxane rubber.Auxiliary agent is a hydroxy silicon oil.
The Banbury mixer that the present invention adopts is the NHZ-6000 Banbury mixer that the aboveground machine works of kneading in Rugao City, Jiangsu Province produces.The rubber oil pressure vulcanizer that adopts is that Cohan reaches the CSD-FS rubber oil pressure vulcanizer that rubber manufacturing machinery ltd produces.
The foregoing description only is to be used for explaining the present invention; And be not construed as limiting the invention; Those skilled in the art can make any change and modification to the present invention under the condition that does not break away from purport of the present invention, and these changes and modification are also within the scope of the invention.
