Described modifying titanium dioxide is made by the raw material of following weight part: aluminium hydroxide 2-4, nano titanium oxide 50-60, silicon carbide 4-6, methyl methacrylate 5-7, antimonous oxide 3-4, terephthalic acid 3-4, dioctyl maleate 3-5, ethylene glycol 5-6, water 50-60; 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.
The modified calcium carbonate that a kind of wear resistance of the present invention strengthens, by following concrete steps, made:
(1) calcium carbonate, silica powder, epoxy resin, nylon 66, molybdenumdisulphide, cupric oxide are added in high-speed kneading machine, be warming up between 70-80 ℃, insulated and stirred half an hour, continue to add except modifying titanium dioxide, pulverize all the other remaining components nutshell, continue to be warming up to 110-130 ℃, be incubated and pour out after 15-20 minute;
(2) by adding appropriate deionized water and pulverize nutshell 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 adds the wear-resisting lubricants such as high wear-resistant carbon black and molybdenumdisulphide, make filler self there is self lubricity to reduce external friction power, thereby reach wear-resisting effect; Add modifying titanium dioxide, increased dispersing property and compatibility performance, thereby produce very strong bonding force, can not reduce the over-all properties of product.For plastics, rubber and paint additive etc.
Specific embodiments
Below by specific examples, the present invention is described in detail.
The modified calcium carbonate that wear resistance strengthens, by following weight part (kilogram) raw material make: calcium carbonate 85, silica powder 2, epoxy resin 5, Vanay 4, nylon 666, molybdenumdisulphide 3, cupric oxide 2, pulverizing nutshell 2, high wear-resistant carbon black 1, brown corundum 2, turps 4, whiteruss 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.
The modified calcium carbonate that a kind of wear resistance of the present invention strengthens, by following concrete steps, made:
