Abstract
The invention relates to high-solid colour filler containing pulp for nano modified aqueous paint and a production method. The high-solid colour filler containing pulp comprises the following components in percentage by weight: 28-52% of calcite powder, 5-10% of calcined kaolin, 6-20% of titanium pigment, 3-5% of talcum powder, 3-5% of wollastonite powder, 0.1% of cellulose, 1-3% of titanate coupling agent and 28.9-29.9% of water. The production method comprises the following steps: adding each component except for the titanate coupling agent into a pulping tank, stirring, dispersing, then adding the titanate coupling agent, stirring fully and dispersing; pumping the prepared mixed material into a sand mill and carrying out four-stage grading ultrafine grinding; and after filtering, preparing the high-solid colour filler containing pulp for the nano modified aqueous paint. The colour filler containing pulp prepared by the method has the characteristics of high solid content, superfineparticle diameter, modification on the organic coating of the surfaces of colour filler particles and little use quantity of the titanium pigment.
Description
Technical field
The present invention relates to color stuffing slurry and production method that a kind of building materials coating material production field is used, particularly a kind of nano modified aqueous paint is with high-solid colour filler containing pulp and production method.
Background technology
At present, existing (tradition) slurry production technique of coating factory:
In the 1st step, assort various color stuffing powders, auxiliary material and water;
The 2nd the step, in pulping tank with above-mentioned material dispersed with stirring;
In the 3rd step, will once grind in the said mixture material suction sand mill;
Existing traditional slurry production technique has following deficiency:
Owing to do not add surface-modifying agent in the color stuffing grinding step, the color stuffing particle surface remains the oleophobic wetting ability, does not have affinity with resin, and the color stuffing particle shows as bad dispersibility in coating system, easily reunites once more.The coating lacquer film toughness of producing is poor, scrubbing resistance not, low in glossiness.
2. owing in the color stuffing grinding step, only once grind, make in the coating color stuffing particle grain size thick, median size has only 20～40 μ m; Particularly most of pigment such as titanium dioxide can not fully disperse, and still are in aggregating state.The coating paint film opacifying power of producing is low, and serious waste titanium dioxide resource has increased production cost.
Summary of the invention
Purpose of the present invention is in order to overcome problem and the shortcoming that prior art exists, provide a kind of nano modified aqueous paint with high-solid colour filler containing pulp and production method, handy the present invention can make vast middle dead small factory under the condition that does not increase a large amount of technology inputs and equipment input, utilize existing resource, just can produce middle and high shelves coating products.
Purpose of the present invention can realize by following technical proposals:
The nano modified aqueous paint high-solid colour filler containing pulp, it forms component by by weight percentage: it is characterized in that: calcite in powder 28～52%, calcined kaolin 5～10%, titanium dioxide 6～20%, talcum powder 3～5%, wollastonite powder 3～5%, Mierocrystalline cellulose 0.1%, titanate coupling agent 1～3%, water 28.9～29.9%, above-mentioned each component except that titanate coupling agent is added dispersed with stirring in the pulping tank, add titanate coupling agent and abundant dispersed with stirring again; Carry out the four-stage grading extra-fine grinding in the mixture shredder with preparation; After filtering, make the nano modified aqueous paint high-solid colour filler containing pulp.
The described nano modified aqueous paint production method of high-solid colour filler containing pulp, it is characterized in that: carry out according to the following steps: (1), the above-mentioned each component except that titanate coupling agent is added dispersed with stirring in the pulping tank adds titanate coupling agent and abundant dispersed with stirring again; (2), carry out the four-stage grading extra-fine grinding in the mixture suction sand mill with the first step; After filtering, make the nano modified aqueous paint high-solid colour filler containing pulp.
After finishing in the 2nd step of original production process step, add 1～3% titanate coupling agent color stuffing powder surface-modifying agent just, and abundant dispersed with stirring;
The 3rd step in the original production process step is improved to the four-stage grading extra-fine grinding with " once grind ", uses 4 grinding tandem workings, classified grinding, makes finally that color stuffing particle median size reaches 0.8～1 μ m fineness in the product; In the level Four extra-fine grinding simultaneously, energy that produces when utilizing extra-fine grinding and thermal energy can make coupling agent that the color stuffing particulate is carried out efficient coating modification, form hydrophobic oleophylic nanometer film on its surface, and making it has excellent affinity with resin.
The slurry products of producing will make the coating products of producing have following good characteristic:
1, high solids content: 68-72% can improve paint film fullness ratio, hardness of paint film.
2, ultra micro particle diameter: median size is 0.8～1 μ m.Can improve gloss of film degree, density and opacifying power, improve the coating film forming properties.
3, the organic coating modification of color stuffing microparticle surfaces: can reduce color stuffing microparticle surfaces energy, reduce the tendency of reuniting greatly, improve coating and store the brushing performance.Can form hydrophobic oleophylic nanometer film, improve the knot and the power of color stuffing and emulsion resin.Can improve paint film intensity, wash-resistant property.
4, make the consumption of titanium dioxide in the coating material production process reduce by 20%, reduce production cost, because production process high pollution, high energy consumption and the resource of titanium dioxide are day by day rare.
The invention has the beneficial effects as follows, use this slurry products,, utilize existing resource, just can produce middle and high shelves coating products making vast middle dead small factory under the condition that does not increase a large amount of technology inputs and equipment input.
