Embodiment 1

[0019] A preparation process for solid wood multilayer composite flooring comprises the following steps:

[0020] (1) Preparation of raw materials: The raw materials are first inspected and divided into equal parts, and unqualified materials with insect eyes, decay and excessive defects are removed.

[0021] (2) Selection of solid wood panels: Multi-layer solid wood composite floors are mostly used in the dry environment in the north, so dimensional stability is extremely critical. In order to prevent cracking and other phenomena in the dry heating season, it is necessary to select one by one, and strictly control the moisture content between 6% and 13%.

[0022] (3) Selection of the base plate: Choose a base plate with no defects and no fractures.

[0023] (4) Rotary cutting and drying of logs: The quality of the base solid wood core board is inseparable from the quality of the finished floor. The solid wood core board cut out by rotary cutting is about 2.2mm thick. It will ...

Embodiment 2

[0032] A preparation process for solid wood multilayer composite flooring comprises the following steps:

[0033] (1) Preparation of raw materials: The raw materials are first inspected and divided into equal parts, and unqualified materials with insect eyes, decay and excessive defects are removed.

[0034](2) Selection of solid wood panels: Multi-layer solid wood composite floors are mostly used in dry environments in the north, so dimensional stability is extremely critical. In order to prevent cracking and other phenomena in the dry heating season, one should be selected one by one, and the moisture content should be strictly controlled between 6% and 13%.

[0035] (3) Selection of the bottom plate: choose a bottom plate with no defects and no fractures.

[0036] (4) Rotary cutting and drying of logs: The quality of the base solid wood core board is inseparable from the quality of the finished floor. The thickness of the solid wood core board cut by rotation is about 2.2 ...

Embodiment 3

[0045] A preparation process of a solid wood multi-layer composite floor comprises the following steps:

[0046] (1) Preparation of raw materials: The raw materials are first inspected and divided into equal parts, and the unqualified materials with insect eyes, decay and excessive defects are removed.

[0047] (2) Selection of solid wood panels: Multi-layer solid wood composite floors are mostly used in dry environments in the north, so dimensional stability is extremely critical. In order to prevent cracking and other phenomena in the dry heating season, one should be selected one by one, and the moisture content should be strictly controlled between 6% and 15%.

[0048] (3) Selection of the bottom plate: choose a bottom plate with no defects and no fractures.

[0049] (4) Rotary cutting and drying of logs: The quality of the base solid wood core board is inseparable from the quality of the finished floor. The thickness of the solid wood core board cut by rotation is about ...

Abstract

The invention provides a solid wood multi-layer composite floor and a preparation process and an assembly method thereof. The preparation process comprises the following steps that core boards are prepared; a base material is prepared: the core boards are assembled into slabs, wherein the assembly method comprises the steps that two core boards are bonded in a texture staggered mode to obtain a double-layer core board, three core boards are bonded in a texture staggered mode to obtain a three-layer core board, two side faces of the three-layer core board are respectively bonded with the side faces of one double-layer core board, and the three-layer core board is same as each core board at the position bonded with each double-layer core board in texture direction; cold press molding is performed; hot-press gluing is performed; sanding treatment is performed. In the assembly method, grooved locking buckles are more stable than traditional transversely and longitudinally staggered and arranged buckles in shape, and the rejection rate caused by grooving is greatly reduced. The base material is formed through core board assembly and then high-temperature high-pressure pressing, and the defect that a wooden material easily deforms, warps, cracks and the like is effectively improved.

Description

technical field [0001] The invention relates to the field of floor production technology, and specifically discloses a solid wood multilayer composite floor, a preparation process and a blank assembly method thereof. Background technique [0002] Solid wood composite flooring, with its advantages of natural environmental protection, thick and warm texture, beautiful and natural texture, etc., is becoming more and more popular in ordinary families. Solid wood composite flooring is divided into three-layer solid wood composite flooring and multi-layer solid wood composite flooring. Three-layer solid wood composite flooring is commonly used in home decoration. The three-layer solid wood composite floor is made of three layers of solid wood veneers cross-laminated. ;The core layer is composed of ordinary soft miscellaneous specification wood slats, the materials are mostly pine, poplar, etc.; the bottom layer is rotary cut veneer, the materials are mostly poplar, birch, pine, ...
