Description

A kind of crystal light tone silica gel formula and working method

Technical field:

The present invention relates to silica gel formula and processing technique field, refer in particular to a kind of crystal light tone silica gel formula and working method.

Background technology:

The silica gel adsorption performance is high, Heat stability is good, stable chemical nature, higher physical strength etc. is arranged, and is a kind of high reactivity sorbing material, belongs to amorphous substance, water insoluble and any solvent, nonpoisonous and tasteless, stable chemical nature does not react with any material except highly basic, hydrofluoric acid.

At present, in silica gel is produced, the silica gel lightness of producing is not high, and density is not high, can not meet some variant production needs.

Summary of the invention:

The objective of the invention is for the deficiencies in the prior art, and a kind of crystal light tone silica gel formula and working method are provided, lightness is high, and density is high, wear-resisting, durable.

For achieving the above object, the present invention adopts following technical scheme, it comprises silica gel materials, vulcanizing agent, silicone oil, mica, titanium dioxide, stannic oxide, it is characterized in that: percentage is: silica gel materials 50%-65%, vulcanizing agent 5%-15%, silicone oil 10%-25%, mica 5%-15%, titanium dioxide 5%-15%, stannic oxide 10%-25%.

A kind of working method of crystal light tone silica gel formula, step is as follows:

(1), mica, titanium dioxide, stannic oxide, with silicone oil, put into the Banbury mixer 5-10 minute that stirs, guarantee to merge fully.

(2), liquid or solid-state silica gel materials add vulcanizing agent to put into the Banbury mixer 10-20 minute that stirs, guarantee to merge fully.

(3), the raw material remix that merges fully in step 1,2, enter Banbury mixer and merge fully, through the 120-190 degree celsius temperature, through hydraulic molding machine or injector, compression molding 180-300 second.

(4), after moulding, then post cure, through 180-260 degree celsius temperature, 2-5 hour.

Beneficial effect of the present invention is: silica gel materials, vulcanizing agent, silicone oil, mica, titanium dioxide, stannic oxide, it is characterized in that: percentage is: silica gel materials 50%-65%, vulcanizing agent 5%-15%, silicone oil 10%-25%, mica 5%-15%, titanium dioxide 5%-15%, stannic oxide 10%-25%, through the 120-190 degree celsius temperature, through hydraulic molding machine or injector, compression molding 180-300 second, post cure again, through the 180-260 degree celsius temperature, 2-5 hour, there is lightness high, density is high, wear-resisting, durable characteristics.

Embodiment:

The present invention includes silica gel materials, vulcanizing agent, silicone oil, mica, titanium dioxide, stannic oxide, it is characterized in that: percentage is: silica gel materials 50%-65%, vulcanizing agent 5%-15%, silicone oil 10%-25%, mica 5%-15%, titanium dioxide 5%-15%, stannic oxide 10%-25%.

A kind of working method of crystal light tone silica gel formula, step is as follows:

(1), mica, titanium dioxide, stannic oxide, with silicone oil, put into the Banbury mixer 5-10 minute that stirs, guarantee to merge fully.

(2), liquid or solid-state silica gel materials add vulcanizing agent to put into the Banbury mixer 10-20 minute that stirs, guarantee to merge fully.

(3), the raw material remix that merges fully in step 1,2, enter Banbury mixer and merge fully, through the 120-190 degree celsius temperature, through hydraulic molding machine or injector, compression molding 180-300 second.

(4), after moulding, then post cure, through 180-260 degree celsius temperature, 2-5 hour.

Product out has that lightness is high afterwards, and density is high, wear-resisting, durable characteristics.Mainly can be applicable on military project, civilian precision optical instrument, electronic apparatus accessory, daily daily necessities.

The above is only preferred embodiment of the present invention, and the equivalence of doing according to the described structure of patent claim of the present invention, feature and principle therefore all changes or modifies, and is included in patent claim of the present invention.
