Embodiment 1

[0018] Add in sequence to the dispersion tank first: 480 parts of demineralized water, 1 part of dispersant, 1 part of wetting agent, 3 parts of preservative, 4 parts of defoamer, 19 parts of ethylene glycol or propylene glycol, and 17 parts of film-forming polymer , 2 parts of water-based ultraviolet absorber; then open the dispersion tank and stir for 20 minutes with a rotating speed of 60 rpm; then continue to add 470 parts of water-based acrylic resin, 3 parts of thickener, and continue to stir for 20 minutes until the materials are all miscible; Then add 0.8 parts of ammonia water to the dispersion tank to neutralize the reaction solution. After the pH value of the reaction solution reaches 8-9, continue to stir for 15 minutes, and check the reaction solution again until the pH value of the reaction solution is stable. Press through a 150um filter to get the finished finishing agent and pack it.

Embodiment 2

[0020] Add in order to the dispersion tank first: 490 parts of demineralized water, 1.2 parts of dispersant, 1.3 parts of wetting agent, 3.2 parts of preservative, 4.2 parts of defoamer, 20 parts of ethylene glycol or propylene glycol, and 18 parts of film-forming polymer , 2.2 parts of water-based ultraviolet absorber; then open the dispersion tank and stir for 18 minutes with a rotating speed of 65 rpm; continue to add 480 parts of water-based acrylic resin, 3.2 parts of thickener, and continue to stir for 18 minutes until the materials are all miscible; Then add 1.2 parts of ammonia water to the dispersion tank to neutralize the reaction solution. After the pH value of the reaction solution reaches 8-9, continue to stir for 15 minutes, and check the reaction solution again until the pH value of the reaction solution is stable. Press through a 150um filter to get the finished finishing agent and pack it.

Embodiment 3

[0022] Add in sequence to the dispersion tank first: 470 parts of demineralized water, 0.7 parts of dispersant, 0.8 parts of wetting agent, 2.7 parts of preservative, 3.7 parts of defoamer, 18 parts of ethylene glycol or propylene glycol, and 16 parts of film-forming polymer 1.8 parts of water-based ultraviolet absorber; then open the dispersion tank and stir for 20 minutes with a rotating speed of 55 rpm; then continue to add 460 parts of water-based acrylic resin, 2.8 parts of thickener, and continue to stir for 15 minutes until the materials are all miscible; Then add 1 part of ammonia water to the dispersion tank to neutralize the reaction solution. After the pH value of the reaction solution reaches 8-9, continue to stir for 15 minutes, and check the reaction solution again until the pH value of the reaction solution is stable. Press through a 150um filter to get the finished finishing agent and pack it.

Abstract

The invention discloses a finishing agent for protecting oil paintings. A preparation technology of the finishing agent comprises the following steps: sequentially adding softened water, a dispersant,a wetting agent, a preservative, an antifoaming agent, ethylene glycol or propylene glycol, a film forming polymer and a water-based ultraviolet absorbent into a dispersing tank; starting the stirring of the dispersing tank after the addition is completed; then adding water-based acrylic resin and a thickener into the dispersing tank, and performing continuous stirring; adding ammonia water intothe dispersing tank to neutralize the obtained reaction solution, and performing continuous stirring after the pH value of the reaction solution reaches 8-9; sampling and detecting the obtained reaction solution until the pH value of the reaction solution is stable; and filtering and packaging: allowing the reaction solution to go through a 150 [mu]m filter screen at normal temperature under normal pressure to obtain the finished product, and packaging the finished product. The preparation technology is safe and environmentally friendly. The finishing agent can be infinitely miscible with water, has no toxic or side effects on producers or users of the oil painting finishing agent, and is sprayed on the surfaces of the made oil paintings to make the surfaces of the oil paintings bright andstriking, the oil paintings have the unique waterproof and anti-ultraviolet irradiation functions and improve the weather resistance and the service life of outdoor oil paintings.

Description

technical field [0001] The invention relates to a finishing agent, in particular to an oil painting protection finishing agent. Background technique [0002] Oil paintings are easy to change color due to the material of their pigments, which greatly affects the artistry of oil paintings, especially large-scale outdoor oil paintings, which are directly exposed to sunlight, long-term direct sunlight, and wind and rain, which will accelerate the premature fading of oil paintings. , the service life is greatly shortened. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, the present invention provides a protective finishing agent for oil paintings, which can protect oil paintings, effectively reduce the fading of oil paints, and delay the service life of outdoor oil paintings. [0004] In order to achieve the above object, a kind of oil painting protection finishing agent that the present invention adopts comprises the following steps...
