Abstract

The invention discloses an anti-cracking type floor. A base course, a crack resistance base paint layer, a glass fiber cloth layer, a mortar layer and a wear-resistant finishing coat layer are successively arranged from bottom to top, a reinforcing mesh is embedded in the mortar layer; and the invention further discloses a construction method of the anti-cracking type floor, and the construction method comprises the following steps that A, firstly, grinding and cleaning the ground are carried out, then a layer of concrete is laid to form a concrete base layer; B, anti-cracking base paint is sprayed on the concrete base layer and drying naturally is carried out; C, glass fiber cloth is laid on the dried anti-cracking base paint; D, mortar is laid on the glass fiber cloth, the reinforcing mesh is embedded in the uncured mortar, tamping is carried out by adopting a vibrator; E, the mortar after tamping is leveled by adopting a scraper blade and naturally solidified; and F, finally, the surface of mortar is painted with wear-resistant finishing coat and drying naturally is carried out to complete the floor construction. The anti-cracking type floor has the advantages of crack resistance, wear resistance, compression resistance, long service life and simple construction technology, and is suitable for large-scale industrialization production.

[0045] C. Lay 2 layers of glass fiber cloth on the dried anti-cracking primer;

[0046] D. Lay mortar on the glass fiber cloth, embed steel mesh in the uncured mortar, and use a vibrator to tamping;

[0047] E. The tamped mortar is leveled with a scraper and cured naturally;

[0048] F. Finally, brush the wear-resistant topcoat on the surface of the mortar. After brushing one layer, let it dry naturally and then brush another layer, and then brush another layer after natural drying, for a total of three times.

[0049] In this example, in terms of mass percentage, the anti-cracking primer in step B consists of 40% castor oil short oil alkyd resin, 20% tribasic chlorinated vinegar resin, 10% calcium zirconate, 5% barium zirconate, 5 % Zirconium nitride, 10% polydimethylsiloxane, 10% nano titanium dioxide.

[0050] In this embodiment, the mortar in step D is composed of the following components in parts by mass: 40 parts of ordinary silicate cement, 15 parts of EVA rubber, 10 parts of calcined phosphogypsum powder, 4 parts of composite water retention stabilizer, hydroxyethyl 3 parts of cellulose, 8 parts of styrene-butadiene copolymer, 5 parts of nano ceramic powder, 6 parts of modified nano calcium carbonate, 5 parts of polypropylene fiber, 2 parts of leveling agent, 8 parts of floor mortar latex powder.

[0051] In this embodiment, the wear-resistant topcoat in step F consists of the following components in parts by mass: 30 parts of epoxy acrylate, 10 parts of styrene-acrylic emulsion, 4 parts of aramid staple fiber, 3 parts of aluminum oxide, 10 parts of etherified amino resin, 7 parts of polysiloxane, 8 parts of light calcium carbonate powder, 4 parts of nano zinc oxide, 3 parts of nano silicon powder.
