Abstract

The invention discloses PU matte color repairing golden oil and a preparation process thereof. The process comprises the following steps: feeding styrene modified alkyd resin and cyclohexanone into a dispersion cylinder, switching on a stirring device switch, regulating the rotating speed to be 1,000 revolutions per minute, and continuously performing stirring for 5 to 8 minutes; feeding matting powder, increasing the stirring rotating speed to be 1,500 revolutions per minute, and continuously performing stirring for 15 minutes; feeding nitrocotton, nitropropane and absolute ethyl alcohol, lowering the stirring rotating speed to be 1,000 revolutions per minute, and continuously performing stirring for 8 to 10 minutes; feeding polyamide wax, a leveling agent, an antifoaming agent and butyl acrylate, lowering the rotating speed to be 800 revolutions per minute, and continuously performing stirring for 5 minutes; discharging the product after dispersion is determined to be completed. According to the PU matte color repairing golden oil and the preparation process thereof, the performance such as leveling performance, cracking resistance and floating resistance is improved to a certain extent compared with that of a similar product; moreover, the PU matte color repairing golden oil is more environment-friendly, and has higher stability.

Description

technical field [0001] The invention belongs to the field of design and manufacturing technology of wood surface coatings, and in particular relates to a PU matte color repair gold oil and a manufacturing technology thereof. Background technique [0002] Many furniture, doors and windows are generally made of wood and artificial wood boards, and neither the wood raw materials nor the artificial wood boards can guarantee the appearance of the surface. The wood raw materials generally have color difference, while the color of artificial wood is dull. A commonly used method for the appearance of utensils, color-repairing paint not only changes the color of wooden utensils, but also allows the texture to be seen, improving the decorative effect of wooden utensils. [0003] With the development of modern decoration, the requirements for PU color repair gold oil on the surface of woodware are getting higher and higher. higher requirements. [0004] In the Chinese patent with the...
