specific Embodiment approach 1

[0011] Specific implementation mode one: combine figure 1 Illustrate that the method of using wicker as a core board to mold the floor at one time in this embodiment is realized in the following steps:

[0012] Step 1: rolling the truncated wicker into a curtain-shaped wooden bundle 2, removing the bark, and then drying, dipping the dried curtain-shaped wooden bundle 2 in glue, and drying the dipped curtain-shaped wooden bundle 2 again, Dried to a moisture content of 15% to 17%;

[0013] Step 2: Put the backboard 1 into the mold, place the dried rubber-impregnated curtain-like wood bundle 2 as a core board on the backboard 1, place the surface board 3 on the curtain-like wood bundle 2, and perform pre-pressing, The pre-pressing pressure is 13Mpa ~ 18MPa to form a pre-pressed slab;

[0014] Step 3: drying and curing the pre-pressed slab together with the mold to form a wicker three-layer composite floor. The curing temperature is 120°C-140°C and the curing time is 3min / mm-5mi...

specific Embodiment approach 2

[0015] Specific implementation mode two: combination figure 1 Illustrate that the method of using wicker as a core board molding floor in the present embodiment also includes step 4: follow-up treatment; sanding the outer surfaces of the front board 3 and the back board 1 of the wicker three-layer composite floor, and then The sides of the wicker three-layer laminate flooring are milled and grooved. The two sides of the wicker three-layer composite floor are sanded to make the surface clean and beautiful, which is convenient for subsequent processing such as painting. The side of the wicker three-layer composite floor is milled with tenons and grooves for easy paving, so that the floor is integrated and mutually restricted, reducing deformation. The undisclosed technical features in this embodiment are the same as those in the first embodiment.

specific Embodiment approach 3

[0016] Specific implementation mode three: combination figure 1 Note that the front board 3 in steps 3 and 4 of this embodiment is a sawn thin board, the thickness of the front board 3 is 4 mm to 6 mm, the back board 1 is poplar veneer or birch veneer, and the thickness of the back board 1 is 2 mm to 4 mm . Sawn veneers are generally precious tree species, such as ash, oak, teak and red sandalwood, etc., the purpose is to decorate beautifully, the wood is hard, and avoid depressions caused by bumps; At the same time, the cost is reduced. In addition, the use of the front panel 3 and the back panel 1 not only improves the dimensional stability of the wicker three-layer composite floor, but also reduces the warping deformation of the wicker three-layer composite floor. The undisclosed technical features in this embodiment are the same as those in the second embodiment.

Abstract

The invention provides a method for forming floor with wicker as core veneer through once compression molding, relates to a method for forming a floor through once compression molding and aims at overcoming shortcomings easy to occur in the fabrication process of the existing wicker three-layer composite floor, such as open joint, debonding and bubbling, and solving the problems of large wood waste, high energy consumption, high manufacture cost, and easy warping and deformation in the use process. The method comprises the steps of rolling the wicker into a curtain wood bunch, removing the bark, drying and gumming, and drying again until the moisture content is in the range from 15% to 17%, next, putting a back plate in a mold, putting the dried gummed curtain wood bunch as a core veneer on the back plate, putting a surface plate on the curtain wood bunch, and pre-compressing under the pre-compression pressure ranging from 13MPa to 18MPa to form a pre-compressed plate blank, and then curing and forming the pre-compressed plate blank by drying to obtain the wicker three-layer composite floor, wherein a curing temperature is in the range from 120 to 140 DEG C, and the time of curing ranges from 3min / mm to 5min / mm. The method is used for forming the floor through once compression molding.

Description

technical field [0001] The invention relates to a method for molding a floor at one time. Background technique [0002] Northeast my country is rich in wicker resources, but there is little research on the rational use of wicker. [0003] Wicker three-layer composite flooring is a kind of surface board, back board and core board glued vertically to each other. It has good dimensional stability, not easy to deform and crack. It not only retains the natural texture of the solid wood floor, but also has the advantages of comfortable foot feeling, sound insulation and cool insulation. However, the existing processing method is to first process the wicker into a core board, and then reassemble it with the front board and the back board, which is formed by adhesive, mechanical processing and hot pressing. Bubbles and other defects. Moreover, during the use of the floor, problems such as warping and deformation are prone to occur due to changes in temperature and humidity. In ...
