Embodiment 1

[0037]A preparation equipment for clean-odor water-based paint produced by slag micropowder, including a reaction kettle, adding water into the reaction kettle, adjusting the rotation speed of the reaction kettle to 500-600r / min, slowly adding hydroxyethyl cellulose to disperse for 5-10 minutes while stirring After 5-10 minutes, add additives such as dispersant and defoamer, stir for 5-10 minutes, then add slag powder, titanium dioxide, talcum powder, heavy calcium powder, etc. into the solution, stir After 20-40 minutes, the fineness of the paint will drop below 50 μm. If the fineness is too high, it needs to be ground to below 50 μm before proceeding to the next step. Reduce the speed to 500 rpm, add emulsion, defoamer, etc., and pass through the odor-cleaning emulsion Add a certain amount of pigment to adjust the system to the required color, and use alkali swelling or polyurethane thickener to adjust the viscosity of the system to 75-110KU.

[0038] Slag micropowder is a n...

Embodiment 2

[0050] A method for preparing a deodorizing water-based paint produced by using slag micropowder, the components and weight percentages of each raw material: 20-30% of water, 10-30% of slag micropowder, 0-10% of titanium dioxide, 0-20% of heavy calcium powder, Kaolin 0-15%, heavy calcium powder 0-15%, talcum powder 0-5%, emulsion 10-50%, additives 3-8%.

[0051] Proceed as follows:

[0052] S1. According to the above ratio, weigh each raw material component, each weight percentage is: water 20-30%, slag fine powder 10-30%, titanium dioxide 0-10%, heavy calcium powder 0-20%, kaolin 0- 15%, heavy calcium powder 0-15%, talc powder 0-5%, emulsion 10-50%, additives 3-8%;

[0053] S2. Add the powder thickener hydroxyethyl cellulose into water, and stir for 10 minutes until a uniform solution A is obtained;

[0054] S3, adding a dispersant and an antifoaming agent to the obtained solution A, and stirring for 10 minutes to obtain a solution B evenly;

[0055] S4. In the solution B ...

Embodiment 3

[0059] A pure odor interior wall paint, the weight of each raw material is: water slag superfine powder is 200kg, rutile titanium dioxide is 100kg, rutile titanium dioxide is 25kg, kaolin is 100kg, talcum powder is 50kg, hydroxyethyl cellulose is 2kg, 4kg of defoamer, 8kg of dispersant, 16kg of film-forming aid, 10kg of freeze-thaw stabilizer, 200kg of emulsion, 5kg of dispersant, 280kg of deionized water, 5kg of alkali swelling thickener, the total mass is about 1t.

[0060] (1) according to above-mentioned proportioning, take each raw material component;

[0061] (2) Add the powder thickener into water, stir for 10 minutes to obtain solution A evenly;

[0062] (3) Add dispersant and defoamer to the obtained solution A, and stir to obtain solution B;

[0063] (4) Slowly add solid powder such as slag micropowder, titanium dioxide, talc powder, mica powder, etc. to the obtained solution B under stirring to avoid agglomeration. If the particle size is greater than 50 μm, grindi...

Abstract

The invention discloses an odorless water-based coating produced by using slag micro-powder, and a preparation method thereof. The preparation method comprises the following steps: adding water into areaction kettle, adjusting the rotating speed of the reaction kettle to 500 to 600 r / min, slowly adding hydroxyethyl cellulose in a stirring state, dispersing for 5 to 10 minutes to form a glue form,adding auxiliary agents such as a dispersing agent and a defoaming agent 5 to 10 minutes later, stirring for 5-10 minutes, then adding slag micro-powder, titanium dioxide, talcum powder, ground calcium carbonate powder and the like into a solution, stirring for 20 to 40 minutes to reduce the fineness of the coating to 50 [mu]m or less, grinding to below 50 [mu]m or less for the next step of operation if the fineness is too high , reducing the rotating speed to 500 r / min, adding an emulsion, a defoaming agent and the like, adding auxiliary agents such as an odor-free emulsion, a coalescing agent and the like, adding a certain amount of pigment to adjust the system to the required color, and adjusting the viscosity of the system to 75-110 KU by using alkali swelling or a polyurethane thickener. No dust pollution or air pollution is ensured in the construction process, and the performance is excellent.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of chemical building materials and solid waste, in particular to an odor-cleaning water-based paint produced by using slag micropowder and a preparation method thereof. Background technique [0002] At present, most water-based paints in the paint market use emulsion as the main film-forming substance. Due to the particularity of the latex paint system, it is necessary to use AMP-95 and ammonia water to adjust the pH of the system. The use of AMP-95 and ammonia water will make the paint irritating and harmful. Gas has a great impact on the health of construction workers and users. [0003] In the existing process of using slag micropowder, it is mainly used in the production of cement, which can increase part of the value of slag micropowder, and acting as a part of filler in coatings can greatly increase the added value of slag micropowder, which is conducive to the development ...
