One of the object of the invention is the shortcoming that exists to existing wall body decoration layer, and a kind of structure that can resist wall body slit muchly is provided.
Another object of the present invention provides a kind of formation method of metope cracking resistance structure.
Technical scheme of the present invention is: metope cracking resistance structure; It comprises: basic unit, layer of cloth and surface layer; Layer of cloth is positioned at the centre of basic unit and surface layer; The component of said basic unit and surface layer is identical, and its compositions in weight percentage is: elastic emulsion 12~25%, cellulose ether 0.15~0.25%, anti-crack fiber 0.1~0.3%, wood fibre 0.2~0.5%, dispersing agent 0.1~0.2%, mould inhibitor 0.1~0.2%, cement 15~25%, perlite 10~30%, glass microballoon 15~35%, flyash 0~30%, water reducing agent 0.5~1%.
Preferably, said metope cracking resistance thickness of structure is 1.5~3.5mm.
Preferably, said layer of cloth is glass fiber layer of cloth or nonwoven layer.
The present invention also provides a kind of formation method of metope cracking resistance structure, by above-mentioned formulation basic unit and surface layer, on metope, smears the basic unit for preparing, again with the layer of cloth shop be pressed in basic unit above, on layer of cloth, be coated with float coat at last.
The invention has the beneficial effects as follows: 1. the cracking resistance structure that the crosslinked slurry of high-ductility and the crosslinked layer of cloth of high-ductility is combined to form has efficient anti-cracking functions such as high tensile, high fracture displacement, high two-way adhesive strength; 2. the crack dynamic of body of wall shows the fatigue failure that is formed by ambient influnence, and the anti-fatigue performance of structure of the present invention is excellent, and ageing resistance is strong, and safety is good; 3. if layer of cloth is local or when overloading on a small quantity, load can be redistributed rapidly and transmit, and makes total be unlikely to forfeiture opposing crack ability, can resist wall body slit long-term effectively in the structure of the present invention.
