Abstract

Color-changing coating for building use of the present invention is made up of color indicator, tackiness agent, solid packing, paint vehicle, pigment, being mainly used in building masonry wall covers with paint, lacquer, colour wash, etc., also be useful for spraying, mixing, the dip treating of iron plate, woodwork, ceramic products, plastering, the invention reside in a kind of coating and can conversion go out multiple different color, it is single to have changed the used building coating color of existing market, immobilize, can not accomplish the situation that one is changeable.

Description

Color-changing coating for building use

The present invention is the building chemical field, is mainly used in architectural decoration coating material, also can be used for spraying, mixing, the dip treating of iron plate, woodwork, ceramic products, plastering.

At present, at home and abroad there is no the report of manufacturing color-changing coating for building use, the building coating of existing coating material production producer manufacturing is dull, changeless color, does not have the changeable function of one.

The look of building coating of the present invention becomes to be done wet degree with environment and changes and different colors, changed that present building coating color immobilizes, a kind of coating is a kind of present situation of color forever, this coating can increase luxurious sense to buildings, for example: the blue look of cooling feeling can appear in this color-changing coating for building use when scorching weather, warm pink colour can appear in clammy, also charming purple can occur when doing wet suiting, the variation of color can be played and change the effect of people's surrounding environment mediator somatic nerves.

Color-changing coating for building use is to be color indicator with six hydration cobalt dichlorides, is made up of tackiness agent, solid packing, paint vehicle and pigment, gets final product manual production, but mechanize production again.

Advantage of the present invention can conversion go out different colors for the coating that adds color indicator six hydration cobalt dichlorides under the cooperation of pigment, advantage with circulation variable color and reciprocal variable color, manufacturing process is simple, cost is low, the per kilogram cost is 3.00 yuan, under normal circumstances do not have the phenomenon of fading, the strong more color changeable effect of Exposure to Sunlight is good more.

The representative transition interval of this coating is:

1 group: white

Powder Purple

Ash

Blue

2 groups: white The colour of loess

Yellowish green Grass green

Above-mentioned color change is reflected by color indicator with the humidity change, as first group, when relative humidity is white 60% the time, at 50% o'clock was pink, was purple at 35% o'clock, was grey at 25% o'clock, relative humidity was blue look at 20% o'clock, when relative humidity gets back to 60%, still be white, humidity fixedly time institute to become gradation of color relevant with the amount of adding color indicator six hydration cobalt dichlorides, how much also relevant with the pigment of adding.

Manufacture method: with six hydration cobalt dichlorides is color indicator, 107 glue, poly-acetic acid second dilute emulsion, methylcellulose gum, Resins, epoxy are tackiness agent, with terra alba, talcum powder, lime carbonate, titanium dioxide is solid packing, turmeric, white horse with a black mane Huang, loess, red vermilion, yellow sodium powder, the sun are red, red iron oxide, husky green, add the grayish green pigment that is, add paint vehicles such as ready-mixed paint or varnish again and make color-changing coating for building use, its proportioning is:

Color indicator 1.9-8%

Tackiness agent 60-75%

Solid packing 28-5%

Paint vehicle 10-5%

Pigment 0.1-10%

Providing a production instance proportioning below is:

Six hydration cobalt dichlorides, 3.5% talcum powder 6%

107 glue, 35% alkyd varnish 5%

Terra alba 10% turmeric 0.5%

Gross weight 100

At first separate six hydration cobalt dichlorides with 107 peptizations, add terra alba, talcum powder and turmeric pigment after whole dissolvings, grind evenly back adding alkyd varnish continuation and ground 50 minutes, whole process is carried out at 35-38 ℃, can pack when fineness reaches 300 orders.
