The utility model relates to the technical field of floors, in particular to a damp-proof and deformation-resistant composite floor which comprises a base plate, a nano
ceramic coating is arranged on the outer side of the base plate, the top of the lower nano
ceramic coating is fixedly connected with the bottom of the base plate, the top of the upper nano
ceramic coating is fixedly connected with a composite
silicate coating layer, and the composite
silicate coating layer is fixedly connected with the bottom of the base plate. And a
moisture-proof structure is arranged on one side of the composite
silicate coating layer. Through cooperation of the base plate and the
moisture-proof structure, when the device is used, the first waterproof layer is a
polyurethane waterproof coating, the
polyurethane waterproof coating has the characteristics of high-strength
tear resistance and good elasticity,
weather resistance, oil resistance,
wear resistance,
ozone resistance and acid and alkali
corrosion resistance, and the second waterproof layer is a
silicone rubber waterproof coating, so that the waterproof layer is not prone to falling off. The
silicone rubber waterproof coating has good waterproofness, permeability, film-forming property, elasticity, cohesiveness and
extensibility, so that dual waterproofness of the floor is facilitated, and the
moisture-proof and deformation-resistant effects of the floor are further improved.
