Embodiment Construction

[0024] Below in conjunction with embodiment, the present invention is further described:

[0025] A preparation method of a composite floor, the manufacturing steps are as follows:

[0026] (1) Preparation of shavings: Select logs with a diameter of more than 60mm, use a shaving machine, and carry out slicing processing along the direction of wood fibers;

[0027] (2) Drying of wood shavings: a rotary drum dryer is used, the drying temperature is not lower than 200 °C, and the moisture content after drying is less than 3%;

[0028] (3) Screening of shavings: The shavings are screened by a drum type screening machine, and the fine materials are separated from the shavings, and the sieve aperture is 12mm;

[0029] (4) Shaving sizing: using airless atomization spraying, the surface raw materials are sizing with different types of glue according to actual needs, and the amount of sizing is within 5%;

[0030] (5) Paving: mechanically oriented paving is adopted, and the longitudi...

Abstract

The invention discloses a preparation method of a composite floor, and belongs to the technical field of building materials. The preparation method of the composite floor comprises the following stepsof preparing wood shavings, drying the wood shavings, screening the wood shavings, sizing the wood shavings, carrying out paving, carrying out hot pressing, sanding, distributing glue, carrying out cold pressing, carrying out hot pressing, cutting edges, pasting paper, carrying out hot pressing, guiding edges, carrying out multi-piece sawing, carrying out double-end milling and inspecting and packaging and storing. Compared with the preparation method of a traditional decorative plate, the preparation method of the composite floor is scientific, the surface layer is refined, the density of the surface layer is large, the proper sizing amount is applied, so that the internal bonding strength of plates is improved, groove milling is facilitated, the water absorption thickness expansion rateis small, and the service life of the plates is prolonged; and moreover, the formaldehyde release amount is low, due to the fact that the transverse strength is increased, the cold and hot circulation resistant index and the cracking performance of the surfaces of the plates are improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a method for manufacturing a floor, in particular to a method for preparing a composite floor. Background technique [0002] Laminate flooring is one type of flooring. Laminate flooring often refers to laminate flooring and solid wood laminate flooring in the market. As one of the important floors for house decoration, laminate flooring has become the existence of people's choice due to its unique advantages. The advantages of laminate floors are: easy to maintain and clean, simple to care for, bright as new, no dirt embedded, easy to clean. The surface of the composite floor is well-painted, has good wear resistance, and does not require too much maintenance; the quality of the composite floor is stable and not easy to be damaged. The fibers are crisscrossed into a net-like stacking combination, which makes the various internal stresses of the wood adapt to each othe...
