Description
Technical field
The present invention relates to rubber and make field, is exactly a kind of composite granule for rubber.
Background technology
Existing rubber item stopping composition used mainly plays strengthening action, increases the strength property of rubber.Existing rubber filling electrodeless powder kind is single, acts on single, cannot meet multiple demands.
Summary of the invention
The object of the present invention is to provide one to play fire-retardant, anti-aging, the composite granule for rubber of strengthening action simultaneously.
Above-mentioned purpose is realized by following scheme:
A kind of composite granule for rubber, it is characterized in that: it is obtained by the raw material of following weight parts: calcium carbonate 60-70, diatomite 30-50, linking agent TAC1.5-2, aluminium nitride 0.4-0.6, antimonous oxide 3-6, anti-oxidant DLTP 1-2, NDZ-401 titanate coupling agent 3-6, dimethyl phthalate 1-2, Octyl adipate 0.5-0.7.
Described a kind of calcium carbonate composite granule for rubber, it is characterized in that, preparation method is:
(1) after diatomite being calcined 1-2 hour at 400-500 DEG C, take out, cooling, grinds to form nanometer powder, obtains nanometer calcined diatomite for subsequent use;
(2), after calcium carbonate being sintered 1-2 hour at 200-300 DEG C, take out cooling, obtain calcination of calcium carbonate, for subsequent use;
(3) will after except diatomite, calcium carbonate, all the other raw materials mix by weight, add suitable quantity of water, 15-25 minute is stirred at 30-35 DEG C, obtain modification liquid, finally nanometer calcined diatomite and calcination of calcium carbonate are mixed, then add modification liquid, 20-30 minute is stirred at 40-50 DEG C, dry again, wear into nanometer powder, to obtain final product.
Beneficial effect of the present invention is: it is good that the composite granule that the present invention prepares manufactures adaptability to rubber, and intensity is high, stable performance, and flame-retardant anti-aging is high temperature resistant.
Embodiment
