Description

Elastic organic grindstone terrace

Technical Field

The utility model relates to a terrace field specifically is an organic grindstone terrace of elasticity.

Background

The grinding stone terrace is an artificial stone with certain decorative effect, which is made by using cement as cementing material, mixing marble or granite broken stone with different colors and different grain sizes, and carrying out the procedures of stirring, forming, maintaining, grinding and the like. Has the advantages that the design and color can be spliced randomly and the color can be prepared by self-definition; the dust is not generated, the cleanliness is high, and the requirements of high-cleanness environments such as pharmacy, chip manufacturing and the like are met; the color is bright and clean; the decorative caulking strips are horizontal and vertical, no gap is needed between the caulking strips, the connection is dense, and the integral aesthetic property is good; the grindstone terrace is suitable for markets, exhibition halls, corridors, high-grade entertainment places, exhibition halls, business clubs and other places needing attractive and wear-resistant ground, and can achieve A1-level fire prevention. The grindstone made of the epoxy adhesive is also called epoxy grindstone or organic grindstone.

The existing grindstone terrace has the technical defect, and the grindstone terrace which is commonly used at present mainly has the defect that the grindstone terrace is easy to crack.

Disclosure of Invention

For solving not enough among the prior art, the utility model provides an organic grindstone terrace of elasticity can effectively avoid grindstone terrace fracture, and the structure is succinct, and convenient construction, and is with low costs.

The utility model discloses a realize above-mentioned purpose, realize through following technical scheme: the elastic organic grindstone terrace comprises a concrete base layer, an anti-cracking damping buffer layer, a high-strength reinforcing layer, solvent-free epoxy resin or solvent-free polyurethane grindstone surface layer which are sequentially combined from the concrete base layer to the top.

The concrete foundation layer is C20 concrete, and the thickness is 200 mm.

The anti-cracking damping buffer layer is a solvent-free polyurethane layer and is 5-10mm thick.

The high-strength reinforcing layer is a solvent-free polyurethane layer or a solvent-free epoxy resin layer, and the thickness of the high-strength reinforcing layer is 2-3 mm.

The thickness of the solvent-free epoxy resin or solvent-free polyurethane grindstone surface layer is 6-12 mm.

The tensile strength of the anti-cracking damping buffer layer is more than or equal to 1.0Mpa, and the breaking tensile rate is more than or equal to 600%.

The tensile strength of the high-strength reinforced layer is more than or equal to 10.0Mpa, and the elongation at break is more than or equal to 100%.

Contrast prior art, the beneficial effects of the utility model reside in that:

1. the utility model adopts the solvent-free polyurethane anti-cracking damping buffer layer as the bottom layer of the grinding stone, which can effectively avoid the grinding stone from cracking, and simultaneously play a role of damping, thus prolonging the service life of the grinding stone; and after the water is fully permeated and cured, the strength can be improved, and the upward volatilization of the base water can be prevented.

2. The setting of crack control shock attenuation buffer layer and high strength strengthening layer avoids the basis because of the fracture phenomenon that expend with heat and contract with cold caused, can effectively reduce the use of material, can save the use of surface course copper bar box, reduces construction steps, reduce cost.

3. The utility model discloses an use environmental protection material, realized that the product has good environmental protection effect, more have the function of feature of environmental protection.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Reference numerals shown in the drawings: 1. a concrete foundation layer; 2. an anti-cracking damping buffer layer; 3. a high-strength reinforcing layer; 4. a solvent-free epoxy resin or a solvent-free polyurethane stone facing.

Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

As shown in figure 1, the elastic organic grindstone terrace comprises a concrete base layer 1, wherein the concrete base layer is arranged on the ground, and the concrete base layer is C20 concrete with the thickness of 200mm and is leveled along with the beating. From the concrete foundation layer 1 to the top, an anti-cracking damping buffer layer 2, a high-strength reinforcing layer 3 and a solvent-free epoxy resin or solvent-free polyurethane grindstone surface layer 4 which are mutually combined are sequentially arranged. The anti-cracking damping buffer layer 2 is a solvent-free polyurethane layer, the thickness is 5-10mm, the tensile strength is more than or equal to 1.0Mpa, the tensile rate is more than or equal to 600%, the solvent-free polyurethane anti-cracking damping buffer layer is used as the bottom layer of the grinding stone, the grinding stone can be effectively prevented from cracking, the damping effect is achieved, and the service life of the grinding stone is prolonged; and after the water is fully permeated and cured, the strength can be improved, and the upward volatilization of the base water can be prevented. The specific product performance detection results are shown in the following table I:
