Abstract
The invention relates to a preparation method of diatom mud environment-friendly interior wall coatings. The preparation method comprises the following steps of: firstly preparing the following materials in parts by weight: 20 of diatomite (325 meshes), 8 of adhesive powder, 0.6 of methyl cellulose, 7 of talc powder (700 to 900 meshes), 15 of calcium carbonate powder (400 to 600 meshes), 10of quartz sand (20 to 90 meshes), 10 of kaolin (750 to 850 meshes), 2 of attapulgite powder (550 to 750 meshes), 2 of titanium dioxide powder, 10 of ash calcium powder (550 to 650 meshes), 14.7 of r heavy calcium carbonate (1200 to 1300 meshes), 0.4 of wood fibers and 0.3 of staple fibers; loading the above materials into a horizontal high-speed dispersion machine according to the given ratio; and dispersing uniformly. The preparation method provided by the invention can produce novel interior wall coatings which are free of VOC (volatile organic compounds), temperature-resistant, fire-proof and wear-resistant and have stable performances, and a long useful service life.
Description
Technical field
The present invention relates to coating and make the field, relate in particular to a kind of preparation method of diatom ooze environment-friendly interior wall coating.
Background technology
Present decorative material for internal wall on the market is mainly aqueous emulsion paint, is again emulsion paint, is divided into polyvinyl acetate emulsion and ACRYLIC EMULSION two large classes, the interior wall coating advantage is that construction is simple, and multiple color tones is arranged, and should intersperse various ornaments thereon, the decorative effect simplicity generosity is widely used.China has tens kind models so far since the development and production eighties, and its fundamental property is identical, basically is comprised of water, pigment, emulsion, weighting agent and various auxiliary agent.But this interior wall coating of being made by emulsion, auxiliary agent etc. has VOC discharging, the heatproof of not preventing fires, contains the shortcomings such as heavy metal.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of have zero VOC, heatproof prevent fires, resistance to wear, have respiratory function, can absorbing formaldehyde, the several functions such as organism of toluene and so on, stable performance, the preparation method of the novel interior wall powdered material that acceptable life is long.
For realizing above purpose, the technical solution used in the present invention: a kind of preparation method of diatom ooze environment-friendly interior wall coating, its preparation method is as follows: at first select 20 parts in 325 purpose diatomite, 8 parts of rubber powders, 0.6 part of methylcellulose gum, 7 parts in 700 orders ~ 900 purpose talcum powder, 15 parts in 400 orders ~ 600 purpose dry powders, 10 parts in 20 orders ~ 90 purpose quartz sands, 10 parts in 750 orders ~ 850 purpose kaolin, 2 parts in 550 orders ~ 750 purpose attapulgites, 2 parts of titanium dioxides, 10 parts of the grey calcium of 550 orders ~ 650 purposes, 14.7 parts in 1200 orders ~ 1300 purpose coarse whitings, 0.4 part of xylon, 0.3 part on staple fibre; Putting into the horizontal high-speed dispersion machine after adding in proportion above-mentioned materials accurately is uniformly dispersed; Described rubber powder is selected the redispersible latex powder of vinyl acetate outsourcing polyvinyl alcohol, and above-described methylcellulose gum is the methylcellulose gum of 20000 viscosity.
Among the present invention, preferred 800 orders of described talcum powder.
Among the present invention, preferred 500 orders of described dry powder.
Among the present invention, preferred 40 ~ 70 orders of described quartz sand.
Among the present invention, preferred 800 orders of described kaolin.
Among the present invention, preferred 600 orders of described attapulgite.
Among the present invention, described titanium dioxide is preferably anatase titanium dioxide, and content of titanium dioxide is greater than 95%.
Among the present invention, preferred 600 orders of described grey calcium, calcium hydroxide content is greater than 90%.
Among the present invention, preferred 1250 orders of described coarse whiting.
Among the present invention, it is thick that described staple fibre is preferably long 24 μ of 6mm.
Beneficial effect of the present invention:
1, health environment-friendly: saved as reaching the auxiliary agents such as the harmful film forming of various liquid chemicals that coating property adds, dispersion, wetting, levelling, anticorrosive mildewproof, VOC free discharging.
2, transportation and storage are convenient: approximately contain 20-50% water in the common coating, and in the diatom ooze new coating, this part water adds just in the time of will arriving on-the-spot the use, that is to say, this part water neither needs transportation, does not also need storage.In addition, moisture coating when transportation and the temperature of storing are lower than 0 ℃, tends to freezingly, and there is not this problem in the diatom ooze powder coating.
3, do not need sanitas: in the conventional liquid coating, existing water, germy grain easily is contaminated by bacterial again.Therefore, for antiseptic, adding preservative agent, and diatom ooze powder coating no bacteria pollution problem does not need sanitas.
4, fire prevention heatproof: in the common coating, hold incendive organism owing to having added, in the process that fire occurs, easily burn and produce a large amount of obnoxious flavoures.And the diatom ooze powder coating is because the inside there is no organism, so the only meeting melting of can not burning under 1000 ℃ high temperature.
5, because diatomite is contained in the powder coating the inside, and diatomaceous vesicular structure has been given the breathing humidity of powder coating, energy balance indoor humidity, and can absorption chamber interior free formaldehyde and oil smoke.
