Problems solved by technology

[0002] Wooden mold is a commonly used mold, and red pine wood is light, soft, fine, straight-grained, and strong in corrosion resistance. It can be used to make wooden molds, but there are still many problems in the process of preparation and use of red pine wood molds. , For example, the existing wooden molds generally have the problem of being easily deformed when exposed to water and moisture, and the surface is not hard enough to be easily scratched and worn, resulting in mold deformation and shortened service life.

Embodiment 1

[0018] 1) Polish the surface of the molded mold, and then apply a layer of ethyl α-cyanoacrylate at a temperature of 32 ° C. When applying ethyl cyanoacrylate, phenolic resin and cuprous chloride are added according to the mass ratio 1:4 compound additives, the amount of additives added is 2% of the mass of ethyl α-cyanoacrylate; dry at 55°C and 37% humidity for 6 minutes;

[0019] 2) Apply water-based water-based paint on the dried mold, and then dry it at 67°C and 43% humidity for 17 minutes to complete the treatment.

Embodiment 2

[0021] 1) Polish the surface of the formed mold, and then apply a layer of ethyl α-cyanoacrylate at a temperature of 28 ° C. The ethyl cyanoacrylate is added with unsaturated polyester resin and cuprous chloride Additives compounded at a mass ratio of 1:3, the amount of additives added is 1% of the mass of ethyl α-cyanoacrylate; dried at 60°C and 40% humidity for 7 minutes;

[0022] 2) Apply water-based water-based paint to the dried mold, and then dry at 68°C and 46% humidity for 18 minutes to complete the treatment.

Embodiment 3

[0024] 1) Polish the surface of the formed mold, and then apply a layer of ethyl α-cyanoacrylate at a temperature of 34 ° C. When applying ethyl cyanoacrylate, phenolic resin and ferric chloride are added according to the mass ratio 1:5 compound additive, the amount of additive added is 3% of the mass of ethyl α-cyanoacrylate; dry at 50°C and 35% humidity for 8 minutes;

[0025] 2) Apply water-based water-based paint on the dried mold, and then dry it at 66°C and 39% humidity for 19 minutes to complete the treatment.

Abstract

The invention discloses a surface treatment method for a wooden mold, and belongs to the technical field of mold treatment. The surface treatment method is characterized by comprising the steps of 1) polishing the surface of the formed mold, then applying a layer of alpha-ethyl cyanoacrylate under the temperature condition of 20 DEG c-40 DEG c and carrying out drying; and 2) then applying water-based paint for woodware on the mold and then carrying out drying so as to complete the treatment. According to the treatment method, in the treatment process, the alpha-ethyl cyanoacrylate is firstly applied, then the water-based paint is applied after drying, and therefore the purposes of greatly improving the hardness, the wear resistance and the waterproof performance can be achieved at the same time.

Description

technical field [0001] The invention discloses a surface treatment method for a wooden mold, which belongs to the technical field of mold treatment. Background technique [0002] Wooden mold is a commonly used mold, and red pine wood is light, soft, fine, straight-grained, and strong in corrosion resistance. It can be used to make wooden molds, but there are still many problems in the process of preparation and use of red pine wood molds. , For example, the existing wooden molds generally have the problem that they are prone to deformation when exposed to water and moisture, and the surface is not hard enough to be easily scratched and worn, resulting in mold deformation and shortened service life. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a surface treatment method for wooden molds that improves hardness, wear resistance and water resistance. [0004] The tec...
