A double-layer composite floor

Abstract

The invention discloses a double-deck combined type floor, and belongs to the field of floors. The double-deck combined type floor is formed by bonding a faceplate of the upper deck and a baseplate ofthe lower deck, wherein the baseplate is made of a PVC stone plastic plate. The upper surface of the faceplate is of an irregular raised grain wearproof surface, and the upper part of the raised grain wearproof surface is covered with a paint coating layer. A baseplate rubber storage tank is arranged on the upper surface of the baseplate in the length direction. A notch structure and a convex opening structure which are in inserted connection with each other are symmetrically formed in the two edges of the baseplate in the length direction, and a notch structure and a convex opening structurewhich are in inserted connection with each other are similarly and symmetrically formed in the two edges of the baseplate in the width direction. The PVC stone plastic plate is made of a PVC stone plastic base material, and the PVC stone plastic base material is prepared by the following steps of step a, raw material mixing and heating; step b, pore generation; step c, extruding and forming; stepd, cooling and forming. According to the double-deck combined type floor, production cost of the double-deck combined type floor is reduced, ecological environment is protected, and the occurrence oftackless and deformation phenomena of the double-deck combined type floor is effectively avoided.

Description

technical field [0001] The invention relates to a floor, more specifically, to a double-layer composite floor. Background technique [0002] At present, composite solid wood flooring is mainly based on multi-layer solid wood composite, and its performance is closer to pure solid wood with three layers. The three-layer solid wood composite floor is composed of three layers of thin solid wood boards through a more complex process. When the three layers are composited, the thinner bottom and surface layer wood grains are arranged vertically, and the thicker middle layer wood grains are arranged horizontally, thus neutralizing the natural deformation of the wood. The surface layer of this three-layer solid wood composite floor is made of high-quality wood (such as: oak, maple, teak, Burmese mahogany, hickory and walnut, etc.), and the middle layer and bottom layer are fast-growing materials with better elasticity ( Such as: pine, poplar, etc.), can effectively solve a series o...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the shortcomings of the existing two-layer composite wood floor, which is high in production cost, destroys the ecological environment, and is prone to glue opening and deformation, and provides a double-layer composite floor, which reduces the The production cost is lower, the ecological environment is protected, and the occurrence of double-layer composite floor glue opening and deformation is effectively avoided.
