Problems solved by technology

At present, the floor curing agent commonly used in the market is a sodium-based salt product with sodium silicate as the main component, which can improve the strength and wear resistance of the floor, but has poor durability; Salt products, the curing effect is more significant, but the dry film formed by the lithium silicate aqueous solution on the smooth surface is discontinuous, poor adhesion, peeling, and powder falling, which cannot effectively prevent the capillary phenomenon of concrete and the phenomenon of efflorescence, and Poor acid resistance
Chinese Patent No. CN102503347A reports a lithium-based concrete sealing and curing agent, although it has the advantages of high compressive strength and wear resistance, and alkali resistance, but the high fluorinated alkyl sulfonate contained in the formula is harmful to the environment. Common pollutants in the environment have been banned, and the seal curing agent is not suitable for long-term use under acidic conditions

Abstract

The invention discloses a lithium-based flooring curing agent and a preparation method thereof. The curing agent is prepared from substances in parts by weight as follows: 50-100 parts of lithium silicate sol, 5-15 parts of N,N-methylene bisacrylamide, 1-3 parts of quartz powder, 0.5-1.5 parts of silicone oil, 1-5 parts of a stabilizer, 0.5-2 parts of calcium sulfoaluminate, 2-6 parts of an anionic surfactant and 3-5 parts of sulfonated acetone-formaldehyde (based superplasticizer). The curing agent can remarkably improve the strength, the Moh's hardness, wear resistance and acid resistance of flooring, has high product permeability, is quick to dry, easy to use, clean and maintain, long in service life, odorless, non-toxic, safe and environment-friendly and has a wide application range.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a lithium-based floor curing agent and a preparation method thereof. Background technique [0002] The floor is a ground that uses concrete to treat the original ground and presents a certain strength and rigidity. Its strength mainly comes from the calcium silicate compound formed by the hydration of silicon and calcium in the cement component in concrete. The interior of the concrete is still undergoing a slow hydration reaction after the initial setting of the concrete. This reaction cannot be completely carried out under natural conditions. There are always a large number of free calcium ions that do not react to form calcium silicate compounds, so the increase in concrete hardness is still large. Have potential. [0003] Floor curing agents seal the floor and create a dense, long-lasting and very hard surface, increasing the life of the floor. At present, the fl...
