A kind of applicable wide strength modified calcium carbonate of the present invention, by following concrete steps, made:
(1) calcium carbonate, zinc hydroxide, styrene-butadiene rubber(SBR), carbon black, kaolin, Magnesium Silicate q-agent, anti-aging agent RD are added in high-speed kneading machine, be warming up between 70-80 ℃, insulated and stirred half an hour, continue to add all the other remaining components except modifying titanium dioxide, montmorillonite powder, continue to be warming up to 110-130 ℃, be incubated and pour out after 15-20 minute;
(2) by adding appropriate deionized water and montmorillonite powder by pouring out material while hot, stir and grind 2-3 hour, form suspension stand-by;
(3) suspension is mixed with modifying titanium dioxide, stir 10-15 minute under 800-1000 rev/min, dry, be ground into ultrafine powder and get final product.
The invention has the beneficial effects as follows: the present invention fills a prescription rationally, production technique is simple, by carbon black, carry out strengthening action, redispersible rubber powder increases toughness, after process of lapping, add modifying titanium dioxide and be coated, not only increased dispersiveness, and economized in raw materials, reduced cost, it is convenient that filler of the present invention can be used for plastics, rubber, coating etc.
Specific embodiments
Below by specific examples, the present invention is described in detail.
An applicable wide strength modified calcium carbonate, by following weight part (kilogram) raw material make: calcium carbonate 85, zinc hydroxide 3, styrene-butadiene rubber(SBR) 5, carbon black 2, montmorillonite powder 2, kaolin 2, Magnesium Silicate q-agent 2, anti-aging agent RD 1, glycerol glycerinate 4, polyvinyl acetate 4, redispersible rubber powder 2, modifying titanium dioxide 3;
Described modifying titanium dioxide by following weight part (kilogram) raw material make: aluminium hydroxide 2, nano titanium oxide 50, silicon carbide 4, methyl methacrylate 5, antimonous oxide 3, terephthalic acid 3, dioctyl maleate 3, ethylene glycol 5, water 50; First preparation method adds methyl methacrylate, nano titanium oxide, aluminium hydroxide, ethylene glycol, water to stir, form suspension, at 45-50 ℃, dry to water content 2-3%, then add immediately terephthalic acid, dioctyl maleate mix and blend 25-35 minute, then add all the other remaining components, under 1200-1500 rev/min of condition, stir, at 50-60 ℃, dry, be ground into ultrafine powder and get final product.
A kind of applicable wide strength modified calcium carbonate of the present invention, by following concrete steps, made:
(1) calcium carbonate, zinc hydroxide, styrene-butadiene rubber(SBR), carbon black, kaolin, Magnesium Silicate q-agent, anti-aging agent RD are added in high-speed kneading machine, be warming up between 70-80 ℃, insulated and stirred half an hour, continue to add all the other remaining components except modifying titanium dioxide, montmorillonite powder, continue to be warming up to 110-130 ℃, be incubated and pour out after 15-20 minute;
