Description
Technical field
The present invention relates to chemical field, particularly a kind of anti-mildew is except the brushing method of methanal paint.
Background technology
At present, in house decoration, the house ornamentation that the objectionable impuritiess such as the formaldehyde bringing with material due to various finishings, benzene homologues, TVOC cause pollute and room air in the exceeding standard of objectionable impurities.Seriously disturbed daily life.This gas that contains formaldehyde of the long-time absorption of human body can give rise to diseases, and serious also can crisis arrive people's life security.Therefore to the room after finishing and the new furniture of buying, to carry out the improvement of room air pollution, and eliminate the pollution of the obnoxious flavour that new furniture brings.With the content that guarantees indoor harmful gas, in the scope of national regulation, people are lived in a healthy environment.
In recent years, lot of domestic and international scientific research institution is all in a kind of safety of development, the efficient method of controlling formaldehyde pollution, as the application number Patent Application Publication that is 200910106091.6 a kind of air purification environment-friendly coating, this system component and weight percent are: water: 35%, talcum powder: 25%, kaolin: 20%, multifunctional assistant: 2.5%, thickening material: 1.5%, compound flow agent: 1.5%, defoamer: 1.5%, wetting agent: 1.5%, antiseptic-germicide: 5%, plant aromatic: 0.5%, film coalescence aid: 2.0%, sanitas: 1.5%, mould inhibitor: 1.5%, dispersion agent: 0.5%, whitening agent: 0.5%.
Although this class coating of the prior art has certain effect for removing formaldehyde, complicated due to its component, the ability that its anti-mildew becomes is poor, goes mouldy and extremely affects the outward appearance of upholstery afterwards.Although wherein also added some mould inhibitors, its effect is still undesirable, the time that opposing is gone mouldy is still shorter.
Summary of the invention
For solving finishing in prior art, with coating anti-mildew, become ability, short problem of time length, one of object of the present invention is to provide the brushing method of a kind of anti-mildew except methanal paint, this coating can effectively be resisted and go mouldy, and effect is lasting, this coating, with the effect of removing formaldehyde, can further guarantee the realization of this coating beneficial effect through the coating of this brushing method brushing simultaneously.
The present invention adopts following technical scheme to realize:
A kind of anti-mildew is except the brushing method of methanal paint, this system component proportioning (by weight) is as follows: 100 parts of polystyrene-acrylic copolymer or acrylic copolymer or Vinyl Acetate Copolymer-acrylic copolymer, talcum powder 26-30 part, auxiliary agent 5-8 part, pigment 6-10 part, antimildew disinfectant 8-10 part, sorbent material 3-5 part, water 40-50 part, described antimildew disinfectant is nano-TiO
2, nano-ZnO and ZrO
2mixture, nano-TiO
2, nano-ZnO granularity be 30～50 nanometers, ZrO
2granularity be-400 orders, three's ratio is TiO
2: ZnO:ZrO
2=(1～2): 1:0.5, described brushing method comprises the steps:
1) pretreatment procedure, first polishes metope to be brushed with sand paper, then carries out surface dust processing;
2) brush priming paint, first the metope after pre-treatment is brushed with common priming paint, at 45 ± 2 ℃, be dried and polish again after 3 hours;
3) again brush priming paint, step 2) metope after processing brushes priming paint again, dryly at 45 ± 2 ℃ after 3 hours, polishes again;
4) above-mentioned coating of the present invention and water are blent according to the ratio of 4-6:1, and the coating diluent that stirs to obtain, the metope after then step 3) being processed is brushed this coating diluent, dry polishing after 5 hours at 30-35 ℃;
5) repeating step 4) method brush again 1 layer of above-mentioned coating diluent;
6) after step 5), brush above-mentioned anti-mildew except methanal paint, under room temperature, dry 2-3 days;
7) spray for the last time above-mentioned anti-mildew except methanal paint; And at room temperature dry 5-7 days.
Wherein said talcum powder granularity is less than 100 microns.
Wherein said auxiliary agent is one or more in dispersion agent, wetting agent, defoamer, thickening material.
Wherein said pigment is ultramarine, titanium dioxide etc.
Described sorbent material is one or more in bamboo charcoal, gac, diatomite, perlite.
The beneficial effect of the coating that the inventive method is prepared is:
Nano-TiO
2based on light-catalyzed reaction, make organic substance decomposing and there is antibacterial effect, utilize the hole that conductor photocatalysis produces and the active oxygen that is formed at semiconductor grain surface and bacterial cell or intracellular composition to carry out biochemical reaction, make Bacteria head unit inactivation and cause necrocytosis.Nano-ZnO itself is exactly a kind of inorganic antiseptic, when contacting with bacterium, zine ion slowly discharges, because zine ion has oxidation-reduction quality, and can react with organic carboxyl, hydroxyl etc., destroy its structure, enter destroy after cell electron transfer system enzyme and with-SH radical reaction, reach sterilization object.After kill bacteria, zine ion can dissociate out from cell, repeats said process.Nano-ZnO, except having the anti-microbial effect of traditional Z nO, also has photocatalytic as nano-titanium oxide, under ultraviolet lighting condition, also can discharge hole and electronics, its Antibacterial Mechanism and TiO
2identical.By by TiO
2be combined with and can play extraordinary antimycotic antiseptic effect with ZnO.Applicant finds, combines on the basis of playing good antibiotic and sterilizing, then coordinate appropriate ZrO at the two
2use, will further improve sterilization antibacterial ability, experiment shows, by the collocation of three's suitable proportion, as the TiO of the application's restriction
2: ZnO:ZrO
2=(1～2): 1:0.5, will be than independent use TiO
2or the lifting of ZnO sterilization effect is more than 50%, than combining, uses TiO
2promote more than 20% with the sterilization effect of ZnO.Thus, coating of the present invention can keep sterilization anti-mildew effect for a long time, extends the work-ing life of mildew-resistant anti-mildew coating.Meanwhile, the sorbent material adding in coating can will may arrive surface to mould various bacterial adsorptions in air.Therefore the combination of antimildew disinfectant of the present invention and sorbent material can effectively be resisted and go mouldy, because the antimildew disinfectant and the sorbent material that adopt are all inorganic components, therefore the anti-effect of going mouldy is lasting.Simultaneously due to sorbent material and nano-TiO
2combination, make this coating with the effect of removing formaldehyde, through measuring and calculating, can make indoor formaldehyde reduce more than 97%.After coating ，Ke Shi family by brushing the application or office space finishing because furniture etc. is moved into and is indoorly caused the problem that indoor formaldehyde concentration exceeds standard to be solved.
Brushing method of the present invention adopts conventional priming paint bottoming, and after bottoming, not be used under absolutely dry condition and polish, by a large amount of experiments, determined and applied the bottom of coating of the present invention and the drying temperature of surface layer, and adopt the diluent of coating of the present invention as the transition layer of prime coat and surface layer, by applying two transition layers, play good linking effect, bottom of the present invention and transition layer all adopt brushing method, guarantee being coated with property and the effect of coating, and simple to operate, convenient, last investment precoat adopts spraying, guarantee surface layer smooth and beautiful appearance, coating through this method of application brushing does not chap, non-scale, method is simple and easy to implement, and it is both artistic and practical to be coated with brushing effects, and can guarantee the realization of coating beneficial effect of the present invention.
