Description

A kind of improved silica production technology
Technical field
The present invention relates to a kind of improved silica production technology.
Background technology
Silica is a kind of acidic oxide, and correspondence hyrate is silicic acid.Silica is the most important compound of silicon. Native silicon dioxide present on the earth accounts for the 12% of earth crustal mass, and its existing forms has crystal type and unformed two major class, It is referred to as silica.Also known as white carbon on silica industry, and it is widely used in the reinforcement of rubber for tire as reinforcing agent.Due to two There is aggregation when rubber organic matter disperses and be inclined in silica inorganic salts, be difficult dispersion, cause silica inorganic salt and rubber Organic matter is difficult to mutually melt, and time of fusion is long.
The content of the invention
The technical problem to be solved in the present invention is to overcome existing defect, there is provided a kind of production work of improved silica Skill, to improve dispersiveness of the silica inorganic salt in rubber inorganic matter.
In order to solve the problems, such as appeal, the invention provides following technical scheme：
A kind of production technology of improved silica, step is as follows：
White carbon is matched with water, the ratio of white carbon and water is 1: 5, is stirred after the completion of proportioning to being uniformly dispersed, High-speed stirred is carried out in white carbon after the completion of proportioning is sent into stirred tank, stirred tank speed is set to 200 revs/min, stirring Temperature in the kettle is set to 60 DEG C~70 DEG C, and hard charcoal black wash is obtained after the completion of stirring, and hard charcoal black wash and silane coupler are matched somebody with somebody Than the ratio of hard charcoal black wash and silane coupler is 1: 0.015, is fed again into carrying out high-speed stirring in stirred tank after the completion of proportioning Mix, stirred tank speed is set to 200 revs/min, temperature setting is 60 DEG C~70 DEG C in stirred tank, after being matched after the completion of stirring Hard charcoal black wash, filtering means dehydration is carried out by the hard charcoal black wash after proportioning, the hard charcoal black wash dehydration 50% after proportioning, is in after the completion of dehydration Half tide is starched, and half tide slurry feeding pulper is carried out into slurrying, dryer is re-fed into after slurrying and is dried, and modified two are obtained after drying Silica.
Improved silica obtained by the present invention has good compatibility and dispersiveness with rubber, greatly reduces two The time of fusion of silica and rubber.
Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.
Embodiment
A kind of production technology of silica, production technology is divided into four-stage to be carried out.
Step one, white carbon and water are matched, the ratio of white carbon and water is 1: 5, after the completion of proportioning stirring to point Dissipate uniform.
Step 2, high-speed stirred will be carried out in the white carbon feeding stirred tank after the completion of proportioning, stirred tank speed is set It it is 200 revs/min, temperature setting is 60 DEG C~70 DEG C in stirred tank, and hard charcoal black wash is obtained after the completion of stirring.
Step 3, hard charcoal black wash and silane coupler are matched, the ratio of hard charcoal black wash and silane coupler is 1: 0.015, it is fed again into carrying out high-speed stirred in stirred tank after the completion of proportioning, stirred tank speed is set to 200 revs/min, in stirred tank Temperature setting is 60 DEG C~70 DEG C, the hard charcoal black wash after being matched after the completion of stirring.
Step 4, the hard charcoal black wash after proportioning is carried out into filtering means dehydration, the hard charcoal black wash dehydration 50% after proportioning has been dehydrated Cheng Houcheng half tides are starched, and half tide slurry feeding pulper is carried out into slurrying, dryer is re-fed into after slurrying and is dried, and are obtained after drying Improved silica.
