Problems solved by technology

[0004] At present, some manufacturers have begun to use plastic materials to replace wood, but they generally use integral plastic (or wood-plastic composite materials) to make the shape of the floor. This kind of floor cannot compare with solid wood in terms of strength, texture, etc. Material of the floor

Abstract

The invention discloses a multi-layer composite floor and a production method thereof. The multi-layer composite floor comprises a PVC substrate layer (1), wherein a wrapper layer (2) is arranged on the upper surface of the PVC substrate layer (1); an oil paint layer (4) is arranged on the wrapper layer (2); the wrapper layer (2) is made of a wood veneer or a bamboo veneer; and a polyurethane bonding layer (3) is arranged between the wrapper layer (2) and the PVC substrate layer (1). The consumption of wood resources can be effectively reduced, and thus the multi-layer composite floor has energy-saving and environment-friendly effects. The multi-layer composite floor also has relatively high structure strength and overall stability.

Description

technical field [0001] The invention relates to a multilayer composite floor and its production method, in particular to a multilayer composite floor and its production method. Background technique [0002] With the rapid economic development, the development of timber resources is getting faster and faster, the earth's vegetation is gradually fading, and the living environment of human beings is precarious. [0003] The flooring industry has a huge demand for wood, so how to reduce the use of wood in the flooring industry has become the key to solving environmental problems. However, in flooring production, wood has many characteristics that are difficult to replace. [0004] At present, some manufacturers have begun to use plastic materials to replace wood, but they generally use integral plastic (or wood-plastic composite materials) to make the shape of the floor. This kind of floor cannot compare with solid wood in terms of strength, texture, etc. Material floor. Con...
