Embodiment 1

[0015] Embodiment 1: the preparation of creamy touch-up paint product

[0016] Biocellulose hydrogel was prepared by static shallow plate fermentation method (8 wt% inoculum of Gluconobacter xylinum, fermented for 5 days at 28°C), the harvested hydrogel was purified, crushed mechanically, and vacuum freeze-dried to constant weight Finally, it is pulverized to the nanometer level with an ultrafine pulverizer to obtain a dry biocellulose powder.

[0017] Take 35kg of deionized water, add 40kg of biological cellulose dry powder, 5kg of composite iron-titanium powder, 10kg of zinc powder, 8kg of aluminum powder, 1kg of silicone leveling agent, 0.1kg of water-based defoamer and 0.9kg of isothiazolinone fungicide , heated to 50°C, and then stirred for 30 minutes to mix evenly to obtain a paste touch-up paint product.

Embodiment 2

[0018] Embodiment 2: the preparation of creamy touch-up paint product

[0019] The biocellulose hydrogel was prepared by dynamic shake flask fermentation (Acetobacter xylinum inoculum 10% by weight, fermented for 7 days at 30°C), the harvested hydrogel was purified and crushed mechanically, and dried with hot air at 60°C to constant weight , and finally crushed to the micron level with an ultrafine pulverizer to obtain a dry biocellulose powder.

[0020] Take 30kg of deionized water, add 45kg of biological cellulose dry powder, 10kg of composite iron-titanium powder, 5kg of zinc powder, 4kg of aluminum powder, 0.4kg of silicone leveling agent, 0.2kg of water-based defoamer and 0.4kg of isothiazolinone fungicide kg, heated to 60°C, and then stirred for 25 minutes to mix evenly to obtain a paste touch-up paint product.

Embodiment 3

[0021] Embodiment 3: the preparation of pasty touch-up paint product

[0022] Biocellulose hydrogel was prepared by static shallow plate fermentation method (9 wt% inoculum of Gluconoacetobacter xylinum, 29°C, fermented for 8 days), the harvested hydrogel was purified, mechanically crushed, and vacuum freeze-dried to constant weight Finally, it is pulverized to the nanometer level with an ultrafine pulverizer to obtain a dry biocellulose powder.

[0023] Take 40kg of deionized water, add 25kg of biological cellulose dry powder, 10kg of composite iron-titanium powder, 8kg of zinc powder, 10kg of aluminum powder, 0.8kg of silicone leveling agent, 0.2kg of water-based defoamer and 1kg of isothiazolinone fungicide , heated to 60°C, and then stirred for 25 minutes to mix evenly to obtain a paste touch-up paint product.

Abstract

The invention relates to an application of a biological cellulose dry powder for preparation of a vehicle paint repairing product. The biological cellulose dry powder is used as a main raw material, and deionized water, a compound iron titanium powder, a zinc powder, an aluminum powder, a levelling agent, a defoamer and a bactericide are further added to prepare a pasty vehicle paint repairing product; the vehicle paint repairing product is smeared at scratches before a paint repairing pen is used, and then the paint repairing pen is used for performing paint repairing. Because biological cellulose has an ultra-fine reticulate structure, the scratches can be filled and levelled up, rust is effectively prevented, the bonding fastness degree of a paint surface with a vehicle body can be further increased, and the aesthetic property after paint repairing is improved.

Description

technical field [0001] The present application relates to a new application of biological cellulose, in particular to the application of biological cellulose dry powder in the preparation of vehicle touch-up paint products. Background technique [0002] Bumps and scratches are often unavoidable during the operation of the vehicle, and if every small bump or scratch is repaired by repainting, since painting requires special equipment and professional personnel, it is necessary Very cumbersome and costly. At present, the most commonly used product on the market for consumers to repair vehicle scratches by themselves is the touch-up paint pen, which has a pen-like appearance, and the cavity in which is filled with paint. When the vehicle is repaired, paint is applied on the scratch by the pen tip. And repair scratches. However, the scratches are usually deep. Although the touch-up pen can make the scratches have the same color as the car body, there will still be marks; Ther...
