Anti-deformation double-layer composite floor

Abstract

The invention discloses an anti-deformation double-layer composite floor and belongs to the field of floors. The anti-deformation double-layer composite floor is formed through bonding of a face plateon the upper layer and a base plate on the lower layer; base plate glue storage grooves are formed in the length direction of the upper surface of the base plate; a notch structure and a bulge structure for mutual inserting are symmetrically arranged at the two edges in the length direction of the base plate, and a notch structure and a bulge structure for mutual inserting are also symmetricallyarranged at the two edges in the width direction of the base plate; and an upper layer of penetrating channels and a lower layer of penetrating channels are uniformly distributed in the length direction of the interior of the base plate and arranged in a staggered mode. A PVC stone plastic plate is a PVC stone plastic base material, and the PVC stone plastic base material is prepared through the following steps of a, mixing and heating of raw materials, b, generating of air holes, c, extrusion forming and d, cooling forming. The production cost of the double-layer composite floor is reduced, the ecological environment is protected, and the glue failure and deformation phenomena of the double-layer composite floor are effectively avoided.

Description

technical field [0001] The invention relates to a floor, more specifically, to a deformation-resistant 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 effect...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the disadvantages of the existing two-layer composite wood floor, which are high in production cost, destroy the ecological environment, and are prone to glue opening and deformation, and provide a deformation-resistant double-layer composite floor, which reduces the number of double-layer composite floors. The production cost of the double-layer composite floor is reduced, the ecological environment is protected, and the double-layer composite floor is effectively avoided from being glued and deformed.
