Problems solved by technology

Since the urea-formaldehyde resin binder used in the production process is a linear urea-formaldehyde oligomer prepared by polycondensation of urea and formaldehyde under the catalysis of acid or alkali, there will be a large amount of free state during the production and subsequent long-term use of the floor According to the test, the volatilization time of formaldehyde is as long as 3-15 years, which seriously pollutes the environment and endangers people's health.

Embodiment 1

[0017] As shown in the accompanying drawings, a multi-layer solid wood composite floor is composed of wood veneers 2, and adjacent wood veneers 2 are provided with bonding joints for bonding and compounding the wood veneers 2 together. Film 3, the adhesive film 3 is made of the following raw materials in parts by weight: HDPE 6098, 40; high-density polyethylene 5000S, 40; anti-aging agent UV-531, 2; LLDPE 7042, 15; EVA260 resin, 13. The adhesive film is made by a blow molding method commonly used in the field of plastics, such as a stretch blow molding method.

[0018] The multi-layer solid wood composite flooring includes a surface layer 1, a core layer 4 and a bottom layer 5; the surface layer 1 and the bottom layer 5 respectively include three layers of wood veneers made of oak wood through rotary cutting. Harder, suitable for use as the surface layer and bottom layer, to improve the strength and wear resistance of the floor; the core layer 4 includes four layers of wood ve...

Embodiment 2

[0023] Embodiment 2: Embodiment 2 is basically the same as Embodiment 1, the difference is that

[0024] The adhesive film in the present embodiment is made of the following raw materials by weight: HDPE 6098, 35; high-density polyethylene 5000S, 35; anti-aging agent UV-328, 1; LLDPE 7042, 10; EVA260 resin, 5 .

[0025] In this embodiment, the surface layer and the bottom layer respectively include five layers of wood veneers made of rotary-cut red oak; the core layer includes five layers of wood veneers made of rotary-cut meranti.

[0026] The high temperature and high pressure conditions in this embodiment are: pressure 2.5MPa, temperature 180°C.

Embodiment 3

[0027] Embodiment three: Embodiment three is basically the same as embodiment two, the difference is that

[0028] The adhesive film in the present embodiment is to select the raw material of following parts by weight to make: HDPE 6098,45; High-density polyethylene 5000S, 45; Antiaging agent UV-329, 1.5; LLDPE 7042,20; EVA260 resin, 20 .

[0029] In this embodiment, the surface layer and the bottom layer respectively include two layers of wood veneers made of black walnut through rotary cutting; the core layer includes six layers of wood veneers made of birch wood through rotary cutting.

[0030] The high temperature and high pressure conditions in this embodiment are: pressure 3 MPa, temperature 195°C.

[0031] The manufacturing method is simple in operation and high in production efficiency; since the adhesive film used is made of the following raw materials HDPE6098, high-density polyethylene 5000S, anti-aging agent UV, LLDPE 7042, EVA260 resin, and is made by blow moldin...

Abstract

The invention discloses a multilayer solid wood composite floor and a manufacturing method thereof. The multilayer solid wood composite floor is formed by compositing a plurality of layers of wood veneers, and a bonding film containing no formaldehyde, which is used for bonding and compositing the wood veneers, is arranged between adjacent wood veneers. The manufacturing method comprises the following steps: the dried wood veneers are placed in sequence according to different material qualities required by a bottom layer, a core layer and a surface layer; a layer of bonding film is arranged between adjacent veneers; under the condition of high temperature and high pressure, the bonding film is heated and melted, so that the adjacent wood veneers are bonded; and when the wood veneers are cooled to a normal temperature, the multilayer solid wood composite floor is acquired. The manufacturing method is simple to operate and has a high production efficiency; and the acquired non-formaldehyde solid wood composite floor is waterproof, is resistant to high temperature, contains no formaldehyde, is an environmentally-friendly and health floor, can not pollute the indoor environment, and is beneficial to the physical health of people.

Description

technical field [0001] The invention relates to the technical field of solid wood floors, in particular to a multi-layer solid wood composite floor and a manufacturing method thereof. Background technique [0002] Solid wood composite flooring is mainly used for indoor floor decoration, and is an important wooden decoration material for families, hotels, hotels and other occasions. At present, the production of solid wood composite flooring is mostly made of wood veneers bonded by hot pressing with urea-formaldehyde resin adhesive. Since the urea-formaldehyde resin binder used in the production process is a linear urea-formaldehyde oligomer prepared by polycondensation of urea and formaldehyde under the catalysis of acid or alkali, there will be a large amount of free state during the production and subsequent long-term use of the floor According to tests, the volatilization time of formaldehyde is as long as 3-15 years, which seriously pollutes the environment and endanger...
