Problems solved by technology

The outer layer can use better wood materials, while the inner layer can use poorer wood materials, so the invention solves the problem of floor deformation, can reduce production costs and save wood, but still does not solve the problem of soft veneer and low density of existing technical wood , easy to crack, and the technical problems of short practical life of the floor
[0010] Although the above-mentioned composite floors use small-diameter wood, which saves a large amount of ordinary logs and expands the use range of wood, the surface technology wood of these composite floors has low density, low hardness, soft texture, weak strength, and easy cracking, which seriously affects the floor. range of use and service life

Embodiment 1

[0086] First, prepare the floor surface

[0087] 1. Veneer dyeing treatment

[0088] 1-1) Spin the fast-growing poplar into poplar veneer with a thickness of 0.8mm, and select the spin-cut poplar veneer without holes, skin and burr, and the moisture content of the veneer is 25-35% in the natural state ,spare;

[0089]1-2) Add wood stains, dyeing auxiliaries (yuanming powder, penetrant, defoamer, etc.) and water to the dyeing machine in proportion, and turn on the circulating pump to make the dye liquor evenly; then heat up and keep The temperature is 90-95°C; then immerse the eucalyptus veneer in the dye solution of the dyeing machine, dye the veneer, check the color to meet the requirements, take out the veneer, clean and filter the dye solution on the surface; among them, according to the veneer The different colors of the veneer are selected, the concentration of the dye solution is 0.3-0.5%, and the dyeing time is 3-8h, which is determined according to the thickness of t...

Embodiment 2

[0136] The procedure is the same as in Example 1, except that the surface of the prepared parquet is subjected to conventional paint coating treatment.

[0137] The concrete method of paint processing of the present invention is as follows:

[0138] 1) Roller primer

[0139] A) Roll coating UV water-based primer (Shanghai Xiechengchang Chemical Co., Ltd.) on the surface of paint-free solid wood composite floor, then adopt infrared drying, sanding, wherein the consumption of water-based primer is 10-20g / cm 2 ;

[0140] B) On the surface of the composite floor coated with the water-based anti-UV primer, the UV sanding primer (Shanghai Xiechengchang Chemical Co., Ltd., B-4235G) was rolled 3 times, and the amount of the UV primer for each roll was 15-30g / cm 2 , use infrared drying after each roll coating, and then carry out anti-UV primer roll coating after sanding;

[0141] 2) Roller coating with wear-resistant paint

[0142] Roll-coat wear-resistant paint (Shanghai Xiecheng...

Embodiment 3

[0148] First, prepare the floor surface

[0149] In the veneer dyeing process, except that the veneer thickness is 1.5mm and the moisture content is 20%, the rest is the same as that of Example 1;

[0150] In the process of preparing wood softener, the weights of SMQ-05, penetrant JFC, peregal O and water were 25kg, 2kg, 6kg, and 100kg respectively; the weight of the first batch of water accounted for 30% of the total weight of water, and the first heating The temperature of heating up is 50 ℃, and the temperature of the second heating and heating is 70 ℃, and the rest are the same as in Example 1;

[0151] In the process of preparing the dipping solution, except the raw material weights are as follows: the weights of urea, formaldehyde, melamine, polyvinyl alcohol, softener and triethanolamine are respectively 200kg, 610kg, 190kg, 50kg, 30kg, 20kg; the pH of the reaction first stage is 7.5, the reaction temperature is 90 ℃, the reaction time is 25min, and the amount of the f...

Abstract

The invention relates to a preparation method of solid wood composite floor which uses compacted and hardened scientific wood skin as a surface layer. The preparation method of the solid wood composite floor comprises the steps of dyeing and drying a gum wood veneer and a poplar veneer, carrying out gum dipping and sealing on the wood skin with a ultrasonic vibration method, assembling the wood skin after the gum dipping is carried out on the wood skin, carrying out semi-solidification hot pressing on the wood skin through a curve mold high-frequency pressing machine, slicing or saw cutting technology square wood into wood skin, assembling the wood skin in the same direction according to required height, carrying out hot-pressing sealing, trimming deflashing, and sanding on the wood skin, surface hardness of painting-free floor manufactured and prepared by the technology wood skin composite raw material with a method for manufacturing solid wood composite floor can reach to more than 3 H, surface hardness of painted solid wood floor can reach to more than 6H, wear-resisting rotating speed can reach to more than 4000 revolutions per minute, cracking can not occur easily, durability of products is improved by more than one time, the service life of the floor is prolonged, and using field of the floor is widened.

Description

technical field [0001] The invention relates to a building home improvement or decoration material and a preparation method thereof, in particular to a composite floor composed of several similar components and a preparation method thereof. Background technique [0002] Flooring has become an important material for ground paving, which is mainly divided into solid wood, reinforced, solid wood composite and bamboo-wood floors. [0003] The development of the floor is first of all the solid wood floor. The upper surface of the original solid wood floor is flat, and the four sides of the floor are right angles. This kind of solid wood floor has very strict requirements on the thickness deviation of the floor during paving. The corners are easily damaged during use. The continuous research and improvement of the solid wood floor has finally formed a solid wood floor with chamfered edges around the floor. [0004] At present, with the continuous improvement of people's living s...
