Description

Technical Field

[0001] The utility model relates to a high-hardness and super-wear-resistant floor coating, belonging to the field of floor coatings. Background Art

[0002] Floor coatings can be widely used in floor construction in petrochemical, textile printing and dyeing, metallurgical industry, and machinery manufacturing, as well as in locomotive roads and various parking facilities.

[0003] The traditional way to protect cement floors is to use solvent-based polyurethane reinforced materials and add quartz sand and other compound paints as a floor protection layer. This has the disadvantages of high solvent content, being environmentally unfriendly, requiring high construction protection, being non-wear-resistant, prone to accumulation and collapse, and having complex construction processes. Utility Model Content

[0006] A primer comprising a first waterborne epoxy resin layer, a waterborne epoxy curing agent, and a second waterborne epoxy resin layer, which are sequentially arranged from top to bottom;

[0007] The topcoat is arranged on the upper side of the primer.

[0008] Preferably, the aggregate base material is in powder form and is made of metal zirconium oxide.

[0009] Preferably, the polyurethane layer is solvent-free moisture-curable polyurethane.

[0010] Preferably, the first water-based epoxy resin layer uses a water-based epoxy resin with a relative molecular weight close to 2000-3000.

[0011] Preferably, the second water-based epoxy resin layer uses a water-based epoxy resin with a relative molecular weight close to 8,000 to 10,000.

[0012] Beneficial effects

[0013] The utility model has excellent physical and mechanical properties, excellent hardness, adhesion and flexibility, and is suitable for large-scale sustainable production and construction; during use, the topcoat dries quickly, has high hardness and strong adhesion. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Other features, objects and advantages of the present invention will become more apparent from the detailed description of the non-limiting embodiments with reference to the following drawings:

[0015] Figure 1 This is a structural diagram of a high-hardness and ultra-wear-resistant floor coating of the utility model; DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] See also Figure 1 The utility model provides a high-hardness and ultra-wear-resistant floor coating technology solution: including:

[0018] A topcoat 1, comprising a quartz powder layer 11, a polyurethane layer 12, an aggregate substrate 13, and a nano-aerogel layer 14, which are sequentially arranged from top to bottom;

[0019] Primer 2, the primer 2 includes a first waterborne epoxy resin layer 21, a waterborne epoxy curing agent 22, and a second waterborne epoxy resin layer 23, which are sequentially distributed from top to bottom;

[0020] The topcoat 1 is arranged on the upper side of the primer 2 .

[0021] The quartz powder layer 11 and aggregate base material 13 are bonded to the polyurethane layer 12 via an organic silicone additive, coating the top and bottom surfaces of the polyurethane layer 12. The organic silicone additive is a commercially available German BYK antifouling organic silicone additive. The nano-aerogel layer 14 is also commercially available, imparting to the topcoat 1 high rigidity, superelasticity, high bending flexibility, and excellent impact resistance.

[0022] Preferably, the aggregate base material 13 is in powder form and made of metal zirconium oxide.

[0023] By combining nano aerogel with a quartz powder layer 11, a polyurethane layer 12, and an aggregate base material 13 as a super wear-resistant topcoat 1, a coating that combines the hard skeleton (aggregate base material 13) and the wear-resistant plastic body (polyurethane layer 12) of the topcoat 1 is realized, and the topcoat 1 has a high hardness, super wear-resistant floor topcoat 1 coating with high cross-linking, acid-resistant, alkali-resistant, and chemical-resistant properties, and is waterproof and moisture-proof. Preferably, the thickness of the topcoat 1 is 40 to 60 um. In one embodiment, the thickness of the topcoat 1 is 50 um, so that it has sufficient wear resistance and does not protrude too much from the coating surface.

[0024] The first water-based epoxy resin layer 21 and the second water-based epoxy resin layer 23 are both made of ZG-106 polysilazane resin and ZG-A02 polysilazane resin with a solid content of >50% from Zhongsi (Quanzhou) New Materials Co., Ltd.

[0025] The water-based epoxy curing agent 22 is used to have excellent adhesion to various substrates 13, and has good film-forming properties and flexibility, so that it can be used to bond with the topcoat 1. Preferably, the thickness of the primer 2 is 190 to 210 um. In one embodiment, the thickness of the primer 2 is 200 um, so that it has sufficient structural strength to support the topcoat 1.
