Embodiment 1

[0033] Such as Figure 1-4 As shown, the embodiment of the present invention provides a kind of negative ion aldehyde deodorizing water agent, comprising 30 parts by weight of ammonium bicarbonate, 15 parts of sepiolite, 50 parts of deionized water, 5 parts of calcium stearate, discoloration 6 parts of powder, 10 parts of thickener, 10 parts of thickener, the thickener is a cellulose thickener, the thickener is a water-based tackifying resin, and the color-changing powder is a conventional pigment, which can be prepared according to the color of the customer's interior decoration .

[0034] A kind of preparation method of negative ion aldehyde deodorizing water agent, concrete preparation method is as follows:

[0035] S1. Weigh ammonium bicarbonate, sepiolite, and calcium stearate in proportion, and grind them separately. The ground powder is sieved, and weighed after sieving to ensure that the proportions are consistent;

[0036] S2. Put the ground and sieved raw materials...

Embodiment 2

[0045] A negative ion formaldehyde-removing and deodorizing water agent, comprising 40 parts by weight of ammonium bicarbonate, 18 parts of sepiolite, 60 parts of deionized water, 7 parts of calcium stearate, 8 parts of discoloration powder, and 13 parts of thickener 15 parts of viscosifying agent, the thickener is cellulose thickener, the viscosifying agent is water-based tackifying resin, and the color changing powder is conventional pigment, which can be specifically prepared according to the color of the customer's interior decoration.

[0046] Ammonium bicarbonate, sepiolite, calcium stearate grinding and sieving standard is 1850 mesh in S1, stirring environment in S2 is 23 degrees Celsius, stirring time in S3 and S4 is 2 hours, and stirring temperature is 18 degrees Celsius, in S6 The vacuum storage temperature is 23 degrees Celsius. Add thickener and viscosifier in S5 and stop stirring when the product viscosity is 4200cP.

Embodiment 3

[0050] Thickeners can be replaced by acrylic thickeners, associative polyurethane thickeners and inorganic thickeners. Polyacrylic thickeners have strong thickening and good leveling properties, and are biologically stable Good resistance, but sensitive to pH value and poor water resistance; the association structure of associative polyurethane thickener is destroyed under the action of shear force, and the viscosity decreases. When the shear force disappears, the viscosity can be restored. It can prevent the sagging phenomenon in the construction process. And its viscosity recovery has a certain hysteresis, which is conducive to the leveling of the coating film. The relative molecular mass (thousands to tens of thousands) of polyurethane thickeners is much lower than the relative molecular mass (hundreds of thousands to millions) of the first two types of thickeners, and will not promote splashing. Polyurethane thickener molecules have both hydrophilic and hydrophobic groups...

Abstract

The invention provides a negative ion formaldehyde-removing odor-removing aqueous solution and a preparation method thereof, and relates to the technical field of production and manufacturing of environment-friendly coatings. The negative ion formaldehyde-removing odor-removing aqueous solution comprises 30-50 parts of ammonium bicarbonate, 15-20 parts of sepiolite, 50-65 parts of deionized water,5-8 parts of calcium stearate, 6-10 parts of color-changing powder, 10-15 parts of a thickening agent and 10-15 parts of a tackifier, the thickening agent is a cellulose thickener, the tackifier is water-based tackifying resin, and the color-changing powder is a conventional pigment and can be specifically prepared according to customer indoor decoration colors. The formaldehyde removing agent disclosed by the invention forms a thin film after being coated on a wall surface, the coating wall surface can be sealed through the film, volatilization of formaldehyde in the wall body is avoided, substances such as ammonium bicarbonate, sepiolite and the like can adsorb formic acid during sealing, the purpose of removing formaldehyde is achieved, and the formaldehyde removing agent can be blended according to the color of the wall body. Wall attractiveness is unaffected.

Description

technical field [0001] The invention relates to the technical field of production and manufacture of environmentally friendly paints, in particular to an anion-removing aldehyde-removing and odor-removing water agent and a preparation method thereof. Background technique [0002] Formaldehyde, colorless and irritating gas, chemical formula HCHO or CH 2 O, molecular weight 30.03, also known as formaldehyde. Irritant to human eyes and nose. The relative density of gas is 1.067 (air=1), and the density of liquid is 0.815g / cm³ (-20°C). Melting point -92°C, boiling point -19.5°C. Soluble in water and ethanol. The concentration of the aqueous solution can be up to 55%, generally 35%-40%, usually 37%, called formaldehyde water, commonly known as formalin (formalin). Reducing, especially in alkaline solution, the reducing ability is stronger. Can burn, steam and air form an explosive mixture, the explosion limit is 7%-73% (volume), and the ignition point is about 300°C. It ca...
