Embodiment 1

[0019] As shown in accompanying drawing 1 and accompanying drawing 2, the base supporting plate 1 used in the present invention is a flat structure, and it is mainly formed by pressing plastic material, or by cement, gypsum, kaolin or magnesite as filler, supplemented with Fiber webs are prepared. The surface of the base supporting plate 1 is flat and smooth, so that when the wall decoration is required, the base supporting plate 1 of the present invention is fixed on the wall by bonding or anchoring, or a combination of the two, and then Paint is applied on the surface of the base pallet 1 .

[0020] When the anchoring method is used alone to fix the base pallet, a 2 to 8 mm thick elastic material gasket, such as a rubber gasket or a polyurethane elastomer gasket and a polystyrene foam gasket, can be placed between the pallet and the mortar.

[0021] The bonding mortar can be polymer elastic mortar, and this polymer refers to acrylic acid or vinyl acetate·ethylene (VAE for s...

Embodiment 2

[0023] As shown in accompanying drawing 3, accompanying drawing 4, accompanying drawing 5 accompanying drawing 6, the base pallet 1 used in the present invention is the form that has anchor, and the cross-sectional shape of anchor 2 shown in accompanying drawing 3, accompanying drawing 4 It is in the shape of "Y". The anchors 2 shown in accompanying drawings 5 ​​and 6 are triangular, and these anchors 2 are all on the facing surface. Bonding or anchoring, or a combination of the two, is fixed on the wall, and then various decorative materials and insulation boards are pasted on the facing surface of the base supporting plate 1.

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 [0001] The invention relates to a method for preventing decorative cracking of building exterior wall coatings. Background technique [0002] Oil-type exterior wall coatings have the advantages of gorgeous luster, super stain resistance and weather resistance, especially the high-end performance of metallic texture paints, which makes them deeply loved by consumers, and thus become the main choice for fashionable and high-end decoration of building exterior walls. coating. However, oil-based metallic paints also have fatal deficiencies. For example, the current technology cannot impart hardness and elasticity to metallic paints at the same time. The lack of elasticity makes oily metallic paints easier to crack after use. This is because the wall base mortar The shrinkage and cracking of the wall and the thermal expansion and contraction of the wall cause the cracking of the paint film. Therefore, it can be considered that the cracks that appear after the use...
