Description

A kind of marble imitating construction process with high elasticity coating

(1) technical field

The present invention relates to a kind of marble imitating construction process with high elasticity coating, belong to building engineering field.

(2) background technology

In the prior art, the parian in the skin ornament materials normally adopts natural real stone paint (different titles such as the title natural real stone paint that has, pottery stone lacquer, rubble lacquer, stone similar paint, emulation mineral varnish).Natural real stone paint is substitute marble, steel extension a kind of, a kind of ornament materials that price is relatively low.Risen at home in the middle and later periods eighties, prevail in the nineties so far.It can copy stone material color, texture effects such as marble, is to the replenishing of decorative material for wall surface, and fills up the vacancy of middle-grade ornament materials.And the price of true mineral varnish is about 1/6 of marble, a steel extension, so true mineral varnish has very big market usage space.

True mineral varnish is to be a kind of external wall decorative material of main base material with natural siliceous sand, at present two problems of ubiquity in actual applications: (1) anti-fouling performance is poor: because true mineral varnish is base-material with quartz sand, quartz sand has corner angle, with the passing of time dust stratification; The big slit of existence between the quartz sand particle, dust, stain, rainwater are difficult to flushing, cause building after true mineral varnish is decorated, and cleaning and rainwater self-cleaning are poor, very dirty, just have a strong impact on the attractive in appearance of building wall after several years; (2) crack resistance is poor: because the product self-characteristic of true mineral varnish limitation does not have elasticity.Can not play the slight crack of metope and well to cover up and to protect effect, metope is in case cracking, and true mineral varnish also can be affected, and water, air etc. can pass true mineral varnish layer and enter body of wall, thereby corrodes body of wall.

(3) summary of the invention

Be to solve the deficiency of parian process using true mineral varnish anti-fouling performance difference and crack resistance difference in the prior art, the invention provides and a kind ofly substitute true mineral varnish, have the parian construction technology that antifouling property is good, cracking resistance is superior with the thick-slurry type elastic coating.

For reaching goal of the invention the technical solution used in the present invention be:

A kind of marble imitating construction process with high elasticity coating, described processing step is as follows:

(1) cleaning metope basic unit repairs the metope defective; Processing base level makes basal plane that loose matters such as greasy dirt, floating sand-lime dirt must not be arranged, and having then needs to remove fully; Basal plane needs smooth, firm, otherwise needs to repair with putty; Basal plane needs dry, moisture content less than 10%, pH＜10, sand finish summer should dry 10 days, winter is more than 20 days, in 20 days summers of concrete, winter is more than 25 days.

(2) evenly be coated with water-based or oiliness seal coat; Seal coat select no specific (special) requirements for use, common water-based or oiliness seal coat all can, can adopt roller coating or spraying, (25 ℃ were generally about 2 hours) can carry out next step construction behind the dry to touch.

(3) evenly spray the thick-slurry type elastic coating, described thick-slurry type elastic coating viscosity number is greater than 50000～300000mpas; Can adopt scaffold, the one spraying application needs will to analyze its concrete color according to the marble model that is provided earlier and constitutes up and down.Such as three look marbles, before construction, just should allocate by a certain percentage respectively according to three colors in the marble so with the thick-slurry type elastic coating.Color degree of closeness in thick-slurry type elastic coating color and the marble tends to determine the degree of last emulation.Also can spray multiple tracks with this one deck of tool actual conditions, specifically determine according to actual effect.

(4) evenly be coated with water-based or oiliness Lacquer finish finish paint.Can adopt technology constructions such as roller coating, spraying, brushing, suggestion is more than 5 ℃.

Described thick-slurry type elastic coating relevant parameter is as follows: viscosity number is 50000～300000mpas, fineness value≤100 μ m, solid masses content 〉=50%.Such as: 1. HDJ-900 elastic outer wall emulsion paint; 2. HDJ-901 elastic outer wall emulsion paint; 3. HDJ-902 elastic outer wall emulsion paint.

Described thick-slurry type elastic coating should have following characteristics: the high-elongation that film (1) (more than 200%), can cover wall body slit, and the overall appearance of filming is lasting; (2) to the body of wall strong adhesion, incrust; (3) can effectively prevent growing of mould and algae, mildew resistance reaches 0 grade; (4) resistance to ag(e)ing reached more than 1000 hours, long service life.

Described Lacquer finish finish paint adopts conventional water-based or oiliness Lacquer finish finish paint to get final product, such as: 1. fluorine carbon finish; 2. the silicon third Lacquer finish finish paint.

Described seal coat adopt common water-based or oil primer all can, such as:

1. HDJ-017 oiliness seal coat; 2. HDJ-007 oiliness seal coat; 3. the HDJ-PUS oiliness is sealed wall primer; 4. the HDJ-ACD oiliness is sealed wall primer; 5. the HDJ-011 water-based is sealed wall primer; 6. the HDJ-011 water-based is sealed wall primer.

Preferably, described processing step is as follows:

(1) the smooth metope of cleaning basic unit impels body of wall moisture less than 10%, pH＜10;

(2) body of wall moisture evenly sprays the oiliness seal coat below 10%, under pH＜10 conditions;

(3) after the oiliness seal coat layer fingertip drying 5～38 ℃, humidity less than 80% condition under even spraying thick-slurry type elastic outer wall emulsion paint;

(4) evenly spray fluorine carbon finish after the latex enamelled coating fingertip drying.

The beneficial effect of parian construction technology of the present invention is mainly reflected in: (1) thick-slurry type elastic coating is more extensive in the color sand of true mineral varnish in the selection allotment of color, and the degree true to nature in the imitative Dali of its finished color effect will be higher than true mineral varnish; (2) the thick-slurry type elastic coating has super superior crack resistance, and its fracture elongation reaches more than 200%, and trickle wall body slit is had no effect to the coating top layer; (3) speciality of the own product exquisiteness of thick-slurry type elastic coating makes finished surface bright and clean relatively, its resistance to soiling than true mineral varnish exceed a lot of doubly, to improving a lot service life of the beautiful decoration effect of building.

(4) specific embodiment

The present invention is described further below in conjunction with specific embodiment, but protection scope of the present invention is not limited in this:

Embodiment 1:

Construction technology:

(1) processing base level: processing base level makes basal plane that loose matters such as greasy dirt, floating sand-lime dirt must not be arranged, and having then needs to remove fully; Basal plane needs smooth, firm, otherwise needs to repair with putty; Basal plane needs dry, moisture content less than 10%, pH＜10;

(2) protection: non-coating area is puted up protection with newspaper, in order to avoid coating stays ill effect after being stained with;

(3) primary coat: evenly spray HDJ-017 oiliness seal coat, can carry out next step construction behind the dry to touch;

(4) main being coated with: 5～38 ℃, humidity are less than under 80% condition, adopt scaffold, one spraying application up and down, according to selected marmorean color, adopt HDJ-900 elastic outer wall emulsion paint, (require approaching more selected marble, the color of required allotment is many more to mix several colors, three kinds of general allotments), adopt the multiple layer spraying of spray gun point type;

(5) cover: behind the main japanning bone dry, evenly spray HDJ-FCZ fluorine carbon finish, should spray two circulations back and forth continuously, guarantee the thickness of skin coat;

(6) cleaning: non-coating area is cleared up.
