preparation example Construction

[0027] A preparation method of LVT floor, comprising the above-mentioned LVT floor, comprises the following steps in turn:

[0028] Step 1: Stir and mix the raw materials for the first time: put PVC resin powder, carbon black, and stabilizer into the mixer in proportion to mix, and add plasticizer to the mixer during the mixing process, and the mixing time is 10 minutes;

[0029] Step 2: Stir and mix the raw materials for the second time: add stone powder to the mixture stirred in Step 1 and stir for 30 minutes;

[0030] Step 3: Internal mixing: transport the mixture mixed in step 2 to the internal mixer for heating and internal mixing to form through the conveyor belt. The internal mixing time is 4 minutes, and the internal mixing temperature is 165°C to 175°C;

[0031] Step 4: Cutting: Cool the raw materials formed in Step 3 and cut them into block-shaped bottom and middle materials;

[0032] Step 5: Hot pressing: Put the bottom material and middle material cut in step 4 in...

Embodiment 1

[0039] An LVT floor, comprising the following components by weight: 63.17 parts by weight of PVC resin powder, 267.49 parts by weight of stone powder, 20.12 parts by weight of plasticizer, 0.52 parts by weight of carbon black, and 0.8 parts by weight of stabilizer.

Embodiment 2

[0041] An LVT floor comprises the following components by weight: 65 parts by weight of PVC resin powder, 246 parts by weight of stone powder, 22.8 parts by weight of plasticizer, 0.64 parts by weight of carbon black, and 0.95 parts by weight of a stabilizer.

Abstract

The invention relates to an LVT floor comprising the following components in parts by weight: 63.17-67.28 parts by weight of PVC resin powder, 223.51-267.49 parts by weight of stone powder, 20.12-25.71 parts by weight of a plasticizer, 0.52-0.95 parts by weight of carbon black, and 0.8-1.2 parts by weight of a stabilizer. The LVT floor has the advantages that because PVC resin powder is an environmentally friendly, non-toxic and odorless renewable resource, the overall environmentally friendly effect and good plasticity of the LVT floor can be ensured, the stone powder can increase the overallopacity and improve the overall flexibility, and carbon black can ensure the stable heat and light resistance effects of the LVT floor, and improve the quality of the LVT floor; because the PVC resinpowder is a hard material, and the addition of the plasticizer can make the LVT floor soft, easy to bend and fold, good in elasticity and easy to shape. In addition, the invention also discloses a preparation method of the LVT floor, and discloses the LVT floor.

Description

technical field [0001] The invention relates to an LVT floor and a preparation method thereof. Background technique [0002] Traditional ceramic flooring, solid wood flooring, and composite flooring have phenomena such as cold feet, easy deformation, and excessive formaldehyde, which can no longer meet people's requirements. There is an urgent need for a soft, non-deformable and environmentally friendly indoor floor. LVT floor, that is, PVC floor, came into being to meet people's needs; the main component of PVC floor is polyvinyl chloride material. PVC flooring is widely used in all aspects of home and business because of its rich patterns and diverse colors. LVT floor is a new type of light-weight floor decoration material that is very popular in the world today, also known as "light-weight floor". It is a popular product in Europe, America, Asia, Japan and South Korea. It has been popular abroad. Since it entered the Chinese market in the early 1980s, it has been widely...
