Description

Nanometer internal wall decorative paint

Technical field

The invention belongs to a kind of nanometer internal wall decorative paint.

Background technology

The finishing material of current building and ornament materials particularly house inner wall; mainly play the effect beautifying indoor and outdoor; make people feel comfortable warm; house is more firm; the material used is generally kaolin, the raw material such as silica ashes, talcum powder, mica powder, titanium dioxide adds dispersion agent, wetting agent, propylene glycol, emulsion, water are in harmonious proportion and form; but the requirement of effect people to environmental protection serving landscaping effect and protection body of wall is more and more higher, puts forward new hope to decorative material for wall surface---finishing material is to the provide protection of HUMAN HEALTH.But generally do not have and kill bacterium, mildew-resistant, absorption ultraviolet function.The poor adhesive force of the coating of current decorated wall surface, easy to be aging dimmed, not enough with the binding property of the original cement bottom layer of body of wall, cause delamination to be peeled off.

Summary of the invention

The object of this invention is to provide a kind of nanometer internal wall decorative paint, to solve the intensity difference that current wall decoration coating exists, sticking power persistence is poor, and the aging decay of luminance brightness is fast; Without the problem of sterilization, gas defence function.

Technical scheme:

Nanometer internal wall decorative paint, comprise the general raw material of nano composite material and making wallcovering, by weight, wherein: step 1,2.0-20 part nano composite material, 9-10 part anatase thpe white powder, 8-10 part coarse whiting, 5-7.5 part wollastonite powder, 7-10 part calcined kaolin, 6-7.5 part talcum powder; By preparation coating total amount, get the 451FQ Mierocrystalline cellulose of 0.3%, the multifunctional assistant AMP-95 of 0.1%, the dispersion agent F200 of 0.4%, the wetting agent X-405 of 0.1%, the defoamer of 0.1% 340 and 29.5% water; Join successively in stirrer, stir 20 minutes with the rotating speed of 450-550 rev/min, through sand mill sand milling, be up to the standards for subsequent use.Step 2, by preparation coating total amount, get the benzene emulsion of 20%, the film coalescence aid of 1%, the defoamer 340 of 0.1%, the multifunctional assistant AMP-95 of the sterilant 623,0.1% of 0.2%, the thickening material 110 of 0.4%, the thickening material H380 of 0.4%, the water of 0.4% is inserted in stirrer successively, stirs 20-30 minute, be up to the standards and be finished product together with the compound that step 1 obtains with the rotating speed of 250-350 rev/min.During batching, wherein nano material can not be less than 2%, and other material, according to feeding in the above-mentioned feeding data area provided, makes all raw material total amounts be 100.

Wherein: formulation of nano composite material: 10-20 part nano-calcium carbonate, 30-40 part nano titanium oxide, 25-35 part water, 15-25 part propylene glycol; Again by aforementioned four kinds of raw material total amount, get: the Mierocrystalline cellulose of 0.3%, the multifunctional assistant AMP-95 of 0.1%, the dispersion agent WinSPerse4050 of 1.5%, the wetting agent X-405 of 0.15%.The rotating speed being not less than 450 revs/min in stirrer stirs 20-30 minute.

The inner wall decorative coating made in the manner described above, have employed nano composite material, has environmental protection, and protection HUMAN HEALTH, particularly has and kill the advantages such as bacterium, virus, absorption decomposing organic pollutant, non-secondary pollution for a long time to indoor.Strong adhesion, flintiness is large, and can not shell and peel off, luster performance does not take off change for a long time.

Embodiment

Below provide embodiment:
