Problems solved by technology

[0005] The first is that for dyed products, it is prone to fading. This is because the plant fiber cannot completely absorb the pigment powder. When the tableware encounters water or other solvents, the color powder is easily dissolved by water or other solvents, causing the product to fade.
[0006] The second is that the surface is easy to soften. This is mainly due to the poor water resistance of plant fiber tableware. When it is in contact with water for a long time, water will penetrate into the tableware, causing the tableware to soften and become unusable.
[0007] The above two shortcomings of plant fiber severely limit its wide application in the catering industry

preparation example Construction

[0029] The embodiment of the present invention discloses a preparation method of plant fiber tableware, comprising the following steps:

[0030] a) After mixing the raw materials evenly, they are hot-pressed to obtain the plant fiber shell; the raw materials include bamboo fiber powder, corn and Starch, urea-formaldehyde resin powder and bran;

[0031] b), grinding the surface of the plant fiber shell;

[0032] c) spraying or dip-coating water-based paint on the surface of the polished plant fiber shell and then drying to obtain plant fiber tableware.

[0033] The above method uses bamboo fiber powder, cornstarch, rice bran and urea-formaldehyde resin as raw materials, first heat-presses to form a shell, and then covers a layer of water-based paint protective film on the surface of the shell to make tableware. The surface of the plant fiber tableware prepared by the method is covered with a water-based paint film, and under the protection of the water-based paint film, exter...

Embodiment 1

[0058] 1. Take 50kg of bamboo fiber powder (50-60 mesh), 10kg of cornstarch, 30kg of urea-formaldehyde resin powder and 10kg of rice bran, mix the above raw materials evenly and pour them into a molding machine for heating and molding. The heating temperature is set to 150 and the pressure is set to is 15MPa. After the molding is completed, the mold is separated, and the plant fiber shell is taken out.

[0059] 2. Use a trimming machine to trim the corners of the plant fiber shell prepared in step 1.

[0060] 3. The surface of the plant fiber shell obtained in step 2 is polarized polished, and then the dust on the surface of the shell is cleaned.

[0061] 4. Add the resin component, curing agent component and water of the water-based paint to the mixer, the amount of water added is 15% of the water-based paint, and then carry out low-speed stirring and high-speed stirring in turn, the speed of low-speed stirring is 175rpm, and the speed of high-speed stirring is 550rpm, the ...

Embodiment 2

[0065] 1. Take 60kg of bamboo fiber powder (40-50 mesh), 5kg of cornstarch, 25kg of urea-formaldehyde resin powder, and 10kg of rice bran, mix the above-mentioned raw materials evenly, pour them into a molding machine for heating and molding, and set the heating temperature to 140°C. Set to 10MPa. After the molding is completed, the mold is separated, and the plant fiber shell is taken out.

[0066] 2. Use a trimming machine to trim the corners of the plant fiber shell prepared in step 1.

[0067] 3. The surface of the plant fiber shell obtained in step 2 is polarized polished, and then the dust on the surface of the shell is cleaned.

[0068] 4. Add the resin component, curing agent component and water of the water-based paint to the mixer, the amount of water added is 12% of the water-based paint, and then carry out low-speed stirring and high-speed stirring in turn, the speed of low-speed stirring is 150rpm, and the speed of high-speed stirring is 500rpm, the water-based ...

Abstract

The invention provides a vegetable fiber tableware and a preparation method of the tableware. The method comprises the following steps: mixing raw materials uniformly, hot pressing and molding to obtain vegetable fiber shell, wherein the raw materials comprise bamboo fiber powder, corn starch, urea formaldehyde resin and rice husk with weight ratio of (4-6):(0.5-2): 2-4):1; polishing the surface of the vegetable fiber shell; spraying or soaking water soluble paint to the surface of the polished vegetable fiber shell, and then drying to finally obtain the vegetable fiber tableware. In the method, bamboo fiber powder, corn starch, urea formaldehyde resin and rice husk are used as raw materials, a shell is formed firstly by hot pressing, then a layer of water soluble paint protection film is coated at the surface of the shell, finally the tableware is obtained. The vegetable fiber tableware prepared by the method is coated with the water soluble paint protection film at the surface, the external water and other solvent are hard to permeate into the vegetable fiber shell under the protection of the water soluble paint film. In this way, the waterproof property and the fading resistance of the tableware are improved.

Description

technical field [0001] The invention relates to the field of catering, in particular to a plant fiber tableware and a preparation method thereof. Background technique [0002] Tableware is a necessity in people's life. In recent years, with the rapid development of the economy, the pace of people's life is also accelerating, and the fast food industry has been able to develop sequentially, which has also caused the market's increasing demand for fast food tableware. Traditional fast-food tableware is mostly foamed plastic tableware, frequent use of foamed plastic tableware will cause harm to human health, and it is not easy to carry out post-processing, and it is easy to cause pollution to the environment. [0003] In order to improve the safety and environmental performance of tableware, plant fibers are used to prepare tableware in the prior art. Plant fiber tableware is made of wheat straw, trough or corn, etc., and the plant fiber is obtained after being separated, and...
