Abstract
The invention discloses a method for avoiding crack the decorate coat on the building, wherein, the invention first fixes base support at the wall, to be coated with decorate and paint, to eliminate the crack of oil metal paint.
Description
Technical field
What the present invention relates to is a kind of method that prevents crazing of outer wall decorative coatings of building.
Background technology
The oil type exterior wall coating material has the advantage of magnificent gloss, superpower resistant and weatherability, and especially the top grade performance of metal-like lacquer makes it be well received by consumers, thereby becomes external wall fashion, the high-grade coating that mainly adopts of decorating.But oiliness metal-like coating exists fatal deficiency equally, such as, present technology just can't be given metal-like lacquer consistency and elasticity simultaneously, flexible disappearance, more easy to crack after making oiliness metal-like coating use, this is because due to the expanding with heat and contract with cold of the shrinkage cracking of body of wall basic unit mortar and body of wall, this contraction and the situation of expanding with heat and contract with cold have caused the drawing crack of paint film, therefore, can think like this, the be full of cracks that oiliness metal-like coating uses the back to occur is inevitable, Here it is the existing congenital flaw of oiliness metal-like coating, this flaw does not go can stay at last sorry, even now, but luxurious texture and foofaraw effect that oiliness metal-like coating is shown still make people not part reluctantly with what one treasures.At present, people are earnestly seeking a kind of method that oiliness metal-like coating uses back appearance be full of cracks that overcomes, and make the use of oiliness metal-like coating more become perfect.For example, some technology has adopted multiple layer anti-crack mastic at present, but complicated because of its construction, cost is high, do not have reliable effect of prestressed not to be accepted.In addition, by retrieval, still not seeing has the technology that can solve this difficult problem to disclose.
Secondly, a few years ago to external wall decorative materials such as porcelain bar brick that exterior wall finishing adopted, mosaics because the restriction of its shortcoming that can't overcome and national policy, near the edge of eliminating, need overhaul again, it is old substrate that this external wall that is using is overhauled what be faced with, and cement mortar basic unit of the coating that decomposes of efflorescence in the sixth of the twelve Earthly Branches and basic unit, insufficient strength, the waterproofing course that can't cover after aging, the porcelain overlay coating of hollowing or the like.At these old basic unit's faces, do not conform to the enterprising luggage decorations of the substrate of requirement of strength, be difficult to carry out new decoration construction on the one hand, be full of cracks do not occur after the decorative paint that is difficult on the other hand to avoid new uses and come off.And how to solve the difficult problem of this respect, there not be the Perfected process of solution at present equally.
Summary of the invention
Purpose of the present invention just provides a kind of method that prevents crazing of outer wall decorative coatings of building, prevents to occur after coating from using the situation of be full of cracks on the one hand, on the other hand, overcomes the deficiency that easily chaps and come off behind difficult construction, the decoration in the old construction wall revision.
Purpose of the present invention is achieved through the following technical solutions, and a kind of method that prevents crazing of outer wall decorative coatings of building comprises the steps:
(1) carries out on the external wall of coatings decoration the method for utilizing stickup, anchoring or stickup and anchoring to combine, anchoring base supporting plate at needs;
(2) applying coatings or paste various ornament materials, heat preservation plate material on the face of substrate supporting plate again.
Substrate supporting plate of the present invention is formed by plastic material compacting, or by cement, gypsum, kaolin, magnesia as filler, be aided with fleece and be prepared from.Described substrate supporting plate can be flexible also can be rigidity, described substrate supporting plate has two kinds of forms, a kind of is plate shaped, another kind is a holdfast shape.
Take the present invention of above-mentioned measure, first anchoring base supporting plate on the metope that needs are decorated carries out the coating of coating or the decoration of alternate manner again on the facing of substrate supporting plate.The be full of cracks of basic unit's mortar can be eliminated like this, even small-sized structure crack can be eliminated; Secondly prefabricated molding substrate supporting plate smooth and bright and clean, can realize the smooth and bright and clean of lacquer painting effectively.On the waterproof aspect that the present invention can also make the cement mortar basic unit face that is coated with charge level, insufficient strength that efflorescence decomposes, can't cover after aging, the porcelain overlay coating, realize architectural decoration on brick wall and cement beam column face, cement sand pulp and coating or bonding putty other basal plane that can't bond, and reach high-grade requirement of decorating.This is because after taking the inventive method, make the substrate that will decorate meet the requirement of the decorative cover of wanting, and can improve intensity, leveling and cracking resistance.Simultaneously, substrate supporting plate of the present invention can be made the lattice base plate of coating lattice, and makes lattice and stitch desired moulding limit, makes coating demonstrate the decoration texture of lattice seam.
Description of drawings
For describing the present invention in detail, described in detail below in conjunction with accompanying drawing:
Accompanying drawing 1 is the structural representation of the plate embodiment of substrate supporting plate among the present invention;
Accompanying drawing 2 is structure left views of the plate embodiment of substrate supporting plate among the present invention;
Accompanying drawing 3 is embodiment structural representations that substrate supporting plate of the present invention has " bifurcation " type holdfast;

Embodiment
Embodiment 1
Shown in accompanying drawing 1, accompanying drawing 2, substrate supporting plate 1 used in the present invention is a flat structure, and it is mainly formed by plastic material compacting, or by cement, gypsum, kaolin or magnesia as filler, be aided with fleece and be prepared from.The surfacing of described substrate supporting plate 1 and bright and clean, like this, when needs carried out wall body decoration, by bonding or anchoring, or the mode that both combine was fixed on the body of wall substrate supporting plate 1 of the present invention, again applying coatings on the surface of substrate supporting plate 1.
When independent employing anchoring process anchoring base supporting plate, can between supporting plate and mortar, place the elastomeric material packing ring of 2 to 8 millimeters thick, such as rubber washer or polyurethane elastomer packing ring and foamed polystyrene packing ring.
Adhesive mortar can be the polymer elasticity mortar, and this polymer is meant acrylic acid or vinyl acetate ethene (being called for short VAE) copolymer emulsion.
Embodiment 2
Shown in accompanying drawing 3, accompanying drawing 4, accompanying drawing 5 accompanying drawings 6, substrate supporting plate 1 used in the present invention is for there being the form of holdfast, holdfast 2 shape of cross sections shown in accompanying drawing 3, the accompanying drawing 4 are " bifurcation " fonts, holdfast 2 shown in accompanying drawing 5, the accompanying drawing 6 is triangles, these holdfasts 2 all are on facing, when needs carry out wall body decoration, substrate supporting plate 1 of the present invention is passed through bonding or anchoring, or the mode that both combine is fixed on the body of wall, pastes various ornament materials, heat preservation plate material again on the facing of substrate supporting plate 1.
