Problems solved by technology

The usual PVC floor has a multi-layer structure. According to the thickness of the product, there are various thickness specifications such as 2.5mm, 3.0mm, 4.2mm, 5mm, 5.5mm, etc. The existing PVC floor products with specifications of 2.5mm and 3.0mm, due to The thickness is relatively thin, usually LVT base material products. This type of product includes a primer layer, a middle material layer, a color film layer and a wear-resistant layer. Among them, the raw materials of the primer layer and the middle material layer include plasticizer DOTP , resulting in poor product stability, large shrinkage and expansion rates

Abstract

The invention provides a plastic floor and a preparation method thereof. The plastic floor comprises a silencing layer, a stone-plastic substrate layer, a color film layer and a wear-resistant layer from bottom to top. The stone-plastic substrate layer is prepared from the following raw materials by weight: 50-65 parts of polyvinyl chloride, 100-120 parts of calcium carbonate, 6-9 parts of a calcium-zinc compound stabilizer, 0.7-0.8 part of stearic acid, 0.5-0.8 part of polyethylene wax, 3-5 parts of an acrylic polymer and 3-5 parts of chlorinated polyethylene. The stone-plastic substrate layer, the color film layer and the wear-resistant layer are subjected to hot-press molding together, and the stone-plastic substrate layer and the silencing layer are bonded by a hot-melt adhesive. The plastic floor of the invention adopts the stone-plastic substrate layer which does not include a plasticizer, so the stability of the plastic floor can be effectively improved and the thickness of theplastic floor can be more accurately controlled; and thus, a thin plastic floor can be more easily prepared. In addition, the silencing layer is arranged and has silencing effect, and good foot feeling can be obtained through reduction in the thickness of the plastic floor.

Description

technical field [0001] The invention relates to the field of floor technology, in particular to a plastic floor and a preparation method thereof. Background technique [0002] Plastic floor, that is, PVC floor, is a floor made of polyvinyl chloride as the main raw material, adding fillers, plasticizers, stabilizers, colorants and other auxiliary materials. The usual PVC floor has a multi-layer structure. According to the thickness of the product, there are various thickness specifications such as 2.5mm, 3.0mm, 4.2mm, 5mm, 5.5mm, etc. The existing PVC floor products with specifications of 2.5mm and 3.0mm, due to The thickness is relatively thin, usually LVT base material products. This type of product includes a primer layer, a middle material layer, a color film layer and a wear-resistant layer. Among them, the raw materials of the primer layer and the middle material layer include plasticizer DOTP , resulting in poor product stability, large shrinkage and expansion rates. ...
