Problems solved by technology

However, because its construction technology is mainly manual operation, its quality is greatly affected by human factors. The common quality problems that are difficult to overcome such as uneven surface, hollowing, cracks, and sanding cover up its own advantages and limit its large-scale use. Floor material is a new type of ground material, which is suitable for the maintenance and renovation of new ground engineering or ground engineering, and it requires mortar to have good fluidity, fast solidification speed, and high strength

Abstract

The invention discloses a manufacturing method of a self-leveling mortar terrace, which comprises the following steps: step 1, preparing the following raw materials in parts by weight: 100-105 parts of epoxy resin, 10-15 parts of dibutyl phthalate, 60-65 parts of acetone, 8-10 parts of ethylenediamine and 60-65 parts of anionic waterborne polyurethane; the preparation method comprises the following steps: adding epoxy resin, dibutyl phthalate, acetone, ethidene diamine and anionic waterborne polyurethane into a reaction kettle, and stirring for 30-60 minutes under the conditions that the temperature in the reaction kettle is controlled to be 65-75 DEG C and the rotating speed is controlled to be 300-500 r / min, so as to obtain a coating A; according to the invention, the pH value is adjusted, so that the raw material of the self-leveling mortar layer can obtain very high strength in the early stage, the raw material of the self-leveling mortar layer is constructed on the asphalt closed base layer, is coated with paint for three times, and is matched with fine river sand, so that capillary pores in the surface of emulsified asphalt can be filled, the closed base layer is formed, and the problem of moisture regain is avoided.

Description

technical field [0001] The invention belongs to the technical field of self-leveling mortar, and in particular relates to a manufacturing method of a self-leveling mortar floor. Background technique [0002] Cement floor and concrete floor are the most widely used traditional floors in my country's building floors. They are famous for their bright surfaces, durability and wear resistance. However, because its construction technology is mainly manual operation, its quality is greatly affected by human factors, and the insurmountable common quality problems such as uneven surface, hollowing, cracks, and sanding cover up its own advantages and limit its large-scale use. Floor material is a new type of ground material, which is suitable for the maintenance and renovation of new ground engineering or ground engineering, and it requires the mortar to have good fluidity, fast solidification speed, and high strength. SUMMARY OF THE INVENTION [0003] The purpose of the present in...
