[0002] In the field of industrial and commercial flooring, the choice of floor coating is crucial to ensure the durability, corrosion resistance and aesthetics of the floor. In the traditional floor coating scheme, the conventional three-layer five-layer anti-corrosion floor construction method is widely used. This method usually involves multi-layer paving, including multiple superpositions of base layer, cloth layer and coating layer to achieve the desired protection effect.

First, the paving process of the layer is cumbersome and requires a lot of manual operation, resulting in low construction efficiency. Second, due to heavy pressure or the rolling back and forth of the transfer vehicle, as well as the influence of the damp season, this type of floor is prone to hollowing and stratification, which reduces the service life and anti-corrosion performance of the floor.

[0032] See also Figure 1 and Figure 2 The present invention provides an LSR floor composite coating. The composite coating mainly includes a penetrating primer coating 1, a sealing primer coating 2, a mortar coating 3, a sealing coating 4, an LSR elastic coating 5 and an LSR anti-corrosion layer 6 from bottom to top. The well-defined structural design ensures the stability and durability of the floor coating.

[0033] In the embodiment of the present invention, the penetrating primer coating 1 is made by coating with a solvent-free penetrating primer, and the ratio of the base polymer to the cross-linking agent is 1:0.5, which can significantly increase the adhesion of the coating and improve the bonding strength between the coating and the base ground, thereby ensuring the stability and durability of the coating. The sealing primer coating 2 and the sealing coating 4 are both made by coating with a solvent-free sealing primer, and the ratio of the base polymer to the cross-linking agent is also 1:0.5. The specific ratio further improves the sealing of the coating, prevents the penetration of moisture and chemicals, and enhances the corrosion resistance and chemical resistance of the coating.

[0034] The mortar coating 3 is made of quartz sand, calcium powder and solvent-free sealing primer in a mass ratio of 2:1:1. The above mixing ratio provides the coating with good mechanical strength and durability. The LSR elastic coating 5 is made of LSR elastic mid-coat material, and the ratio of its base polymer to cross-linking agent is 1.5:1, while the LSR anti-corrosion layer 6 is also made of LSR anti-corrosion topcoat material, and the ratio of its base polymer to cross-linking agent is also 1.5:1.
