Indoor composite floor based on phosphorous magnesium materials and self-leveling gypsum, and construction method of indoor composite floor

Abstract

The invention discloses an indoor composite floor based on phosphorous magnesium materials and self-leveling gypsum. The indoor composite floor based on the phosphorous magnesium materials and the self-leveling gypsum comprises a concrete base layer and is sequentially provided with the concrete base layer, a gypsum self-leveling leveling layer and a phosphorous magnesium material self-leveling face layer from bottom to top, and the gypsum self-leveling leveling layer is located between the concrete base layer and the phosphorous magnesium material self-leveling face layer. A construction method of the indoor composite floor comprises the steps of preparation of equipment and tools, base layer treatment, construction of the gypsum self-leveling leveling layer, construction of the phosphorous magnesium material self-leveling face layer, curing, polishing and waxing, and the like. Aiming at solving the problems that organic self-leveling materials are high in construction cost and proneto peeling, and the self-leveling materials taking the gypsum as basic materials are poor in water resistance and abrasion resistance, the provided indoor composite floor has early strength and is short in coagulation time, short in curing time, high in mechanical strength, not prone to cracking, free of hollowing, high in breaking resistance, high in water resistance, high in abrasion resistance,good in flowing property and low in cost, the construction period is short, and the construction efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to an indoor composite floor based on phosphorus-magnesium materials and self-leveling gypsum and a construction method thereof. Background technique [0002] Self-leveling materials, also known as functional floor decoration materials, are a type of material that can quickly, economically and effectively obtain a flat, firm or decorative floor. When this kind of material is used, it is mixed with water according to the specified ratio or the powder and liquid are mixed evenly. After mechanical pumping or manual construction, there is no need for manual paving and vibrating to level off, but depends on the high flow of the slurry. It flows automatically and forms a smooth surface. Self-leveling gypsum is the abbreviation of self-leveling ground leveling gypsum, also known as gypsum-based self-leveling mortar. Dry powder mortar for leveling the ground. Se...

Problems solved by technology

[0003] Among the above-mentioned self-leveling materials, inorganic self-leveling is a traditional practice in my country. Cracks, peeling, and sanding all appear, and some are even quite serious. After repeated repairs after use, the cracks are still difficult to eliminate. Due to frequent repairs, the surface It is uneven and the color is different, which is not beautiful, but also affects the use and has a long construction period; among them, the gypsum self-leveling material in the inorganic self-leveling material is mainly made of α-hemihydrate gypsum, and various related additives (such as retarder Coagulant, water reducing agent, water retaining agent, etc.), an air-hard self-leveling material, due to its poor water resistance and wear resistance, and high cost, its application is limited

Organic self-leveling is a new method that has emerged in recent years. The phenomenon of peeling and sanding has been improved, and the surface smoothness, flatness, and wear resistance have also been improved, but the phenomenon of cracks still cannot be eliminated.

Epoxy or polyurethane self-leveling wear-resistant floor surface is smooth and wear-resistant, but its flatness is completely dependent on the flatness of the concrete base, the air permeability is poor, and the moisture content of the base is high. If the control is not good, hollowing and peeling will easily occur. The early strength is low, the initial setting time is long, the construction procedure is complicated, and the surface is prone to scratches, and the anti-skid and wear-resistant properties cannot meet the engineering design requirements

[0004] Therefore, aiming at the problems that the self-leveling materials based on epoxy and polyurethane are expensive and easy to shell, while the self-leveling materials based on gypsum have poor water resistance and wear resistance, which limits their application. An indoor composite floor with high water resistance and abrasion resistance, high flow performance and low cost is particularly important
