Abstract
The present invention provides a diatomite rubber reinforcing agent, which relates to a nonmetallic mineral product of diatomite. The present invention is characterized in that the product of the present invention replaces white carbon black, and is used as a reinforcing agent in rubber; the rubber reinforcing agent of high quality and low price is prepared by the serial processing processes of raw material selection, separation, impurity elimination, drying in kiln, crushing, winnowing, coupling agent addition, etc.
Description
Technical field
The present invention relates to nonmetalliferous ore Tetramune diatomite.
Background technology
In rubber item,, add the functional inorganic filling strengthening agent for reaching required various physical strengths.At present used strengthening agent has two kinds: black rubber is with carbon black, light-colour rubber white carbon black.Product of the present invention is a light color, mainly substitutes white carbon black.Manufacturing of white carbon black will be made acidic silicasol with water glass and hydrochloric acid after chemical reaction earlier, adds complicated technologies such as conditioning agent Hybrid Heating catalysis again in reactor with alkaline water glass, so cost height, price height.
Summary of the invention
The purpose of this invention is to provide a kind of make simple, price is low, the rubber reinforcing filler of excellent property.
But product replacing whole white carbon black of the present invention, its advantage is:
1. processing performance eats that powder soon, easily wraps roller, removing from mould is effective;
2. mechanical property improves the tensile strength of rubber item, reduces tension set simultaneously;
3. stable, heat-resisting, acidproof, the insulation of chemical property;
4. complete processing is simple, cost is low, price is low, only is 60% of white carbon black.
Embodiment
Machining process is as follows:
1. select its SiO of raw material diatomite for use
2Content is more than 85%, the algae kind with microscler for well.Pulverize during through seasoning water content 20%, sorting, remove impurity.
2. the material of choosing is put into dry kiln and carry out drying, 200 ℃ of temperature, 1 hour time, material moisture is reached below 5%, kiln is selected dynamic kiln for use, multiple modes such as the optional fuel oil of thermal source, combustion gas, electric heating.
3. treat that dry materials comes out of the stove well, through pulverizing, selection by winnowing, select the fine powder of particle diameter below 20 μ m, put into coating device, add silane coupling agent, coating will be selected for use and can be made diatomite and the abundant bonding apparatus of coupling agent.The coupling agent add-on is 2 ‰ of a diatomite weight-10 ‰.The selected silane coupling agent model of the present invention is KH-845-4.
Claims (1)
1. a diatomite rubber reinforcing agent is characterized in that, selects raw material SiO for use
2Content reaches more than 85%, after raw material anhydrates through the kiln drying, pulverizing, selection by winnowing go out particle diameter at the following fine powder of 20 μ m, add silane coupling agent again, the temperature of dry materials is 200 ℃, time is 1 hour, and dry back material moisture reaches below 5%, and the add-on of silane coupling agent is 2 ‰ of a diatomite weight-10 ‰.
