Rapid-hardening terrace material and preparation method thereof

Abstract

The invention discloses a rapid-hardening terrace material comprising following components, by weight, 30-34 parts of Portland cement, 5-10 parts of high-aluminum cement, 35-45 parts of quartz sand, 0.08-0.22 parts of a water reducing agent, 0.06-0.13 parts of a defoaming agent, 0.6-1.5 parts of a redispersible latex powder, 2.5-4 parts of gypsum powder, 0.1-0.2 parts of a retarder and 0.1-0.15 parts of a thickening agent. A preparation method of the rapid-hardening terrace material comprises following steps: (1) mixing the components uniformly to obtain a mixture material; and (2) adding water to the mixture material with stirring uniformly with an addition amount of the water accounting for 20-22% of the total mass of the mixture material. The rapid-hardening terrace material can be dried and hardened rapidly, is good in anti-shock performance, is not liable to swelling, is gravity roller compaction resistant, is good in joint performance with concrete ground, is sun-tolerant and is especially suitable for repairing and renewing old terraces and constructing a new terrace.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a fast-hardening floor material suitable for repairing or laying floor materials on factory floors and parking lot floors and a preparation method thereof. Background technique [0002] Epoxy floor paint is currently used as the main floor paint due to its excellent physical properties and low price. Epoxy resin floor paint is a floor paint formed by mixing epoxy resin and curing agent. Its advantage is that it can bear a certain weight and will not produce dust after grinding, which ensures the cleanliness of the site; in addition, epoxy resin Floor paint can also play an anti-static role. [0003] However, epoxy resin as a floor material also has the following great disadvantages: First, epoxy floor paint cannot be directly bonded to the concrete floor well, and there are often gaps between the two due to the difference in density or hardness. Drums; secondly, epoxy resin it...

Problems solved by technology

[0003] However, epoxy resin as a floor material also has the following great disadvantages: First, epoxy floor paint cannot be directly bonded to the concrete floor well, and there are often gaps between the two due to the difference in density or hardness. Drums; secondly, epoxy resin itself is not resistant to sunlight, it will powder when exposed to sunlight, and needs to be repaired regularly; thirdly, the drying time of epoxy resin is relatively long, generally 28 days, and it cannot be applied in a short time
