Description

Processing method and finished product of wooden curtain blade

technical field

The present invention is related to wooden curtain blades, and more specifically refers to a processing method and finished products of wooden curtain blades.

Background technique

The curtain blades used by the existing blinds are made of PC or aluminum, but the above-mentioned materials are likely to cause environmental pollution during processing; The processing of curtain blades is gradually adopted by the industry to reduce environmental pollution.

In the production process of the above-mentioned wooden panels, after being sterilized, anti-corrosion and dehydration, the surface of the panels must be painted and painted to prevent the wooden panel structure from being exposed to the sun, damp or insects. It is true that although the curtain blades made of wooden panels are rich in texture, the general wooden panels are painted with oil-based paint in the process of painting (including primer and topcoat operations). However, it is sequentially covered on the surface of the plate, but the use of this oil-based paint for coating processing still has the following disadvantages:

First, oil-based paint has a pungent smell. When the paint operator works in an environment full of pungent smell for a long time, it will slowly cause adverse effects on his own health.

Second, the oil-based paint composition contains solvents that can pollute the environment. Therefore, every painting operation will cause damage to the environment.

The 3rd, because this wooden sheet must go through at least multiple roads of painting and coating processing to ensure quality, therefore, when the wooden sheet is after each feeding and painting process, it is still necessary to wait for the oily paint to dry before proceeding. The subsequent blanking (or the next coating process) operation can be continued. Although the wood panels that have been primed (or topcoated) will be air-dried in the production process by means of fans, etc., the drying If the time is too long, the processing efficiency cannot be improved.

Fourth, following the above third point, in order to achieve accurate drying treatment, it is common in the coating operation process of each cycle, such as adding air-drying equipment, extending the transmission distance, or adding a collection air-drying area during the coating operation process Among them, adding air-drying equipment, extending the transmission distance, or adding a collection and air-drying area will be used to enhance drying. However, these methods not only increase the cost, but also consume space.

In view of this, the inventor of the present case has thought carefully, and has been engaged in the production and research and development experience of curtains for many years, and finally has the generation of the present invention.

Detailed ways

Please refer to Fig. 1 to shown in Fig. 3, the processing method of wooden curtain blade of the present invention, mainly is to carry out the surface treatment of the wooden sheet material that has finished sterilization, anticorrosion and dehydration etc.

And in the embodiment of the present invention, be the wooden sheet that the surface non-wood grain presents as the coating object, the processing steps of the present invention in order to achieve the above-mentioned purpose are described below:

A. Feed material:

First, the wooden board material with non-wooden grain on the surface is conveyed in a predetermined direction.

B. Colorant coating operation:

The water-based coloring agent is applied to the surface of the wooden sheet material in step A by spraying the first layer, and then left to stand for 1 minute so that the coloring agent is more stable attached to the surface of the wooden sheet, and then, Use far-infrared rays to dry the wooden sheets coated with colorants. It is better to control the far-infrared irradiation temperature in step B between 60°C and 80°C, and the irradiation time is about 2-4 At the same time, after the far-infrared rays are irradiated, a hot fan must be blown to shorten the drying time; so far, the surface of the wooden plate presents a preset pattern color, such as wood grain.

C. Primer coating operation:

The wooden board treated in step B is also sprayed so that a water-based transparent primer is covered on the wooden board with a predetermined pattern on the surface. After a short period of standing, it is irradiated with far-infrared rays , and the far-infrared irradiation temperature in this step C is preferably controlled between 50°C-60°C, and the irradiation time lasts for about 2 minutes, and then blows with a hot fan to make the primer dry quickly;

And in this step C, after the far-infrared rays are irradiated, the wooden boards can also go through at least one cycle of surface sanding, water-based primer spraying, short standing, and far-infrared irradiation again (the temperature is controlled at Between 60°C and 80°C, the best irradiation time is 4 minutes, and blowing with a hot fan, etc., to make the primer layer solid and the surface smooth.

D. Topcoat coating operation:

It also uses a water-based topcoat that is transparent after drying to spray on the dried wood board with primer, and then after standing for 1-2 minutes, it is continuously irradiated with far-infrared rays with an irradiation temperature controlled at about 60 °C. About 2 minutes, and cool down by blowing with a hot fan, so that a fast drying effect can be obtained, and in this step D, another far-infrared ray irradiation can be applied again (the irradiation temperature is controlled at about 80°C, and the irradiation time 2 minutes is best) with a hot fan to ensure that the topcoat is completely dry and protects the primer layer.

E. Cutting:

After the above-mentioned steps have been processed and the topcoat has been dried, the wooden boards are collected, so that the required curtain can be obtained after the assembly operation.

The above is the processing method of the wooden curtain blade of the present invention, and its structure is as shown in Figure 4, which is a wooden plate 10, a coloring layer 20, a primer layer 30 and a top coat in sequence from the inside to the outside Layer 40.

In addition, the composition of the water-based primer in step C is controlled at 85% acrylic acid polymer (Acrylicemulsion Binder), 0.1% ammonia water (Ammonia), 5% pure water (DeionicWater), 1-3% zinc stearate (Znst Stearate), 2-5% butyl glycol (Buty1-Glcol), 2-5% dispersant (Dispersant), 0.3% defoamer (Defoamer), 0.3% anti-mold agent (Fungicidal Agent) and 0.3% thickener (Thckener) are better; while in step D, the water-based topcoat components are controlled at 95% acrylic PU copolymer (Copolymer of Acrylic PU), 0.1% triethylamine ( Triethylamine), 4% of pure water (Deionic Water), 1% of butyl glycol (Butyl-Glc01), 0.1% of wetting agent (Wetting Agent), 0.1% of fungicidal agent (Fungicidal Agent), 0.1- 0.3% thickener (Thckener) and 0.1-0.3% defoamer (Defoamer) are preferred.

Finally, the advantages of the present invention are organized as follows:

1. The present invention uses far-infrared radiation as the main drying treatment after painting, which can shorten the drying time and improve the processing efficiency. It improves the shortcomings of traditional painting drying, which requires a lot of equipment, consumes space, and takes a long drying time.

2. Same as point 1, because the far-infrared rays have a long wavelength and relatively low energy, so there is no concern about burns when used, and it has better safety. It does not use infrared rays to easily cause burns to human skin and damage eyes. Crystal and other disease problems.

3. The present invention uses water-based paint as the raw material for painting and coating, and there will be no pungent smell during the painting process, and there is no disadvantage of solvent polluting the environment.

4. In the colorant coating operation of the present invention, water-based colorants of different colors can be selected according to requirements, and the selected color can be displayed after being covered with a transparent primer and a transparent topcoat.

In addition, it must be mentioned that if the technology of the present invention is applied to the coating of wooden boards with wood grain on the surface, the colorant coating operation can be omitted, and the transparent primer and topcoat can be directly applied. , which makes the curtain blades present the most original wood grain.

To sum up, the present invention has its advanced practicability among similar products, and it is convenient to use. Moreover, the present invention has no similar articles seen in publications or public use before the application. Therefore, the present invention has already met the conditions for an invention patent. , so apply in accordance with the law.
