Abstract

This invention and prepares side for a kind of multi-functional dry powder coating France, its characteristic is including the inorganic becomes the membrane material, pigment, color Sand, natural building stones, function packing, adopt the white cement and not have Machine as become phosphate membrane material go on membrane into, adopt the diatom Soil, oxidize the zinc (or nanometer oxidizes the zinc) ultraly and detailedly as the function Packing, utilize natural color sand, feel of building stones with abundant The three-dimensional behavior ability of the coating, mix the resin first while preparing And then, then process in grinding the equipment, act as the packing one Son one up to more than 250 eye directlies on average, sieve, packaging. Originally inventing actually could follow the consumption, regulated and needed with water Viscidity go on because it construct, in whether normal atmospheric temperature become membrane, can adopt Brush and roll scribbling and spraying way, has overcome the liquid at present Keep the difficult shortcoming after making the pot.

Description

Multifunctional dry powder coating and preparation method

Affiliated technical field

The invention belongs to paint field, refer in particular to a kind of multifunctional dry powder coating and preparation method.

Background technology

Institute room and furniture often distribute poisonous and deleterious gas at present, have endangered HUMAN HEALTH, and is indoor relatively moister in summer simultaneously, and winter, air was too dry, and existing coating all is difficult to head it off.

Summary of the invention

The objective of the invention is for improving the problem of above-mentioned existence, provide a kind of environmental protection diatomite material of natural nuisance-free that adopts as functional stuffing, the absorption obnoxious flavour, humidity in the surge chamber adopts the zinc oxide with sterilizing function to give the multifunctional dry powder coating and the preparation method of coating sterilizing function as functional additive.

Feature of the present invention is to comprise inorganic filming substance matter, pigment, color sand, natural rock, functional stuffing, and concrete proportioning is (mass ratio):

Inorganic filming substance matter comprises: white cement 5-30%, aluminium dihydrogen phosphate 5-20%; Solidifying agent: zinc oxide 5-15%;

Pigment and filler comprise: diatomite 20-60%, and an amount of pigment, building stones 0-10%, color husky 0-10%,

The methylcellulose gum CMC 0-5% that contracts, sodium-metaphosphate 0-5%.

This coating producing process is as follows:

With after the mixed with resin, on grinding plant, process then earlier,, sieve, packing when the filler grain median size reaches more than 250 orders.

The present invention adopts white cement and inorganic phosphate to carry out film forming as filmogen, adopt diatomite, super fine zinc oxide (or nano zine oxide) as functional stuffing, and the texture of utilizing natural color sand, building stones is to enrich the three-dimensional performance ability of coating, this dry powder multifunctional coating can be according to usage quantity, water is adjusted to needed viscosity and constructs, film forming can adopt brushing and roller coating and spraying method at normal temperatures, has overcome present liquid and has opened the shortcoming of irritating back preservation difficulty.

The present invention has following advantage compared with prior art:

1). have the absorption obnoxious flavour and regulate atmospheric moisture and sterilizing function.

2). it is easy to use easily to construct

3). cheap

4). weather resisteant is good

Embodiment

Embodiment 1:

This coating is prepared from (mass ratio) by following set of dispense ratio:

Diatomite 60%, aluminium dihydrogen phosphate 10%, white cement 20%, the methylcellulose gum 1% that contracts, zinc oxide 7%, sodium-metaphosphate 2% (dispersion agent)

Preparation process is: according to aforementioned proportion, respectively with filmogen, diatomite and other material be by after mixing, and adopts the dry powder shredder to pulverize grinding, be ground to the mean particle size of requirement after, sieve packing.

Embodiment 2:

This coating is prepared from (mass ratio) by following set of dispense ratio:

White cement 18%, aluminium dihydrogen phosphate 4%, zinc oxide 10%, diatomite 58%,

Natural color stone 4%, natural rock 4%, the methylcellulose gum 1% that contracts, sodium-metaphosphate 1%

The preparation method is with embodiment 1.

Described embodiment only is used to illustrate technical solution of the present invention, is not limited to the present invention.

Claims

1. a multifunctional dry powder coating is characterized in that comprising inorganic filming substance matter, pigment, color sand, natural rock, functional stuffing, and concrete proportioning is (mass ratio):
