Plastic-wood floor and manufacturing method thereof

Abstract

The invention relates to a plastic-wood floor and a manufacturing method thereof. The plastic-wood floor is composed of a plastic layer located on an upper layer and a plastic-wood layer located on a lower layer. The plastic layer is composed of an abrasion-resistant layer, a printing color film layer and a medium material layer. The abrasion-resistant layer comprises, by weight, 80-100 parts of pvc resin powder, 2-5 parts of stabilizers and 25-30 parts of plasticizers; the medium material layer comprises, by weight, 80-100 parts of pvc resin powder, 40-45 parts of plasticizers, 2-5 parts of stabilizers and 360 parts of calcium carbonate; and the plastic-wood layer comprises, by weight, 40-50 parts of wood powder, 25-35 parts of polyvinyl chloride, 1-3 parts of coupling agents, 8-10 parts of stabilizers, 3-5 parts of flexibilizer, 1-3 parts of foaming agents and 25-35 parts of calcium carbonate. The floor is good in stability and low in processing cost, and the warping degree, contractility and the expansion rate are obviously reduced.

Description

Technical field [0001] The invention involves a wooden floor and its manufacturing method. Background technique [0002] The main components of the current plastic flooring are: PVC, calcium carbonate, plasticizer and stabilizer, and the floor structure is also a multi -layer plastic composite structure, which can be used for assembly and use through grooves. [0003] The current composition and composition of the plastic flooring are not conducive to the size stability of the product. The processing process and venue requirements of the product are relatively high. In order to improve the size stability of this type of product, the constant temperature room with a large area must be established to form in forming in forming in forming in forming in forming in forming in forming in forming in forming.Before, a large amount of steam high -temperature treatment is needed to ensure the size stability of the product, which is a waste of resources and venues. [0004] In order to impr...

AI Technical Summary

Problems solved by technology

[0003] The composition and structure of the current plastic flooring are not conducive to the dimensional stability of the product. The processing technology and site requirements for the product are relatively high. In order to improve the dimensional stability of this type of product, it is necessary to establish a constant large-area constant temperature room. Before that, a large amount of steam high temperature treatment is required to ensure the dimensional stability of the product, which is a waste of resources and space

[0004] In order to improve the dimensional stability of this type of product, a large amount of calcium carbonate is added to the formula for modification treatment, so the overall density of the product is relatively high, resulting in inconvenient shipment
