Embodiment 6

[0028] Example 6: The components and contents of Example 6 and Example 3 are the same, but in the second step of the production process, the quaternary ammonium salt cationic fluorocarbon surface is first added to the high molecular weight polytrifluoropropylmethylsiloxane The active agent is mixed evenly, and then ethanol is added and mixed evenly.

Embodiment 7

[0029] Embodiment 7: The components and contents of Embodiment 7 and Embodiment 3 are all the same, but in the step 2 of the production process, ethanol is first added to the high molecular weight polytrifluoropropylmethylsiloxane and mixed evenly, and then the quaternary Mix the ammonium salt cationic fluorocarbon surfactant evenly.

Embodiment 1

[0057] The production methods of the wood coating compositions of Examples 1 and 2 are the same, and only the proportions of low molecular weight polytrifluoropropylmethylsiloxane and high molecular weight polytrifluoropropylmethylsiloxane are different. However, the Example 2 wood coating composition performed better than the Example 1 wood coating composition. Therefore, it can be concluded that when the weight ratio of the low molecular weight polytrifluoropropylmethylsiloxane and the high molecular weight polytrifluoropropylmethylsiloxane is 1:1, the wood coating composition of the present invention can be significantly improved. performance.

[0058] Meanwhile, the production methods of the wood coating compositions of Examples 4 and 5 are the same, and only the proportions of low molecular weight polytrifluoropropylmethylsiloxane and high molecular weight polytrifluoropropylmethylsiloxane are different. However, the Example 4 wood coating composition performed better th...

Abstract

The invention relates to a timber coating compound. The timber coating compound comprises the following raw materials in parts by weight: 30-40 parts of low molecular weight polytrifluoropropyl methylsiloxane, 30-40 parts of high molecular weight polytrifluoropropyl methylsiloxane, 15-20 parts of polyvinyl alcohol, 1-1.5 parts of a quaternary ammonium salt cationic fluorocarbon surfactant, 70-80 parts of water, 10-15 parts of ethanol, 1-1.5 parts of camphorquinone, 1-1.5 parts of propylene glycol monooleate, and 1-1.5 parts of an aqueous sterilizing agent. The timber coating compound is used for protecting timber, and can effectively guarantee non-discolouring of a coating film.

Description

technical field [0001] The invention relates to the technical field of coatings, more specifically, it relates to a wood coating composition and a production process thereof. Background technique [0002] Wood is one of the main natural materials for industry, agriculture, national defense, and civil use today. It has many advantages such as easy processing, natural beautiful patterns, luster, and color, and is widely used in furniture and other occasions. However, due to water, bacteria, lignin, etc., natural wood will slowly rot and change color after processing, swell and shrink when wet, and then deform and crack. Rapid aging, yellowing, blackening. [0003] The patent document of the existing application publication number CN105209511A discloses a wood coating composition. Although the wood coating formulation has improved water repellency while maintaining coating properties such as transparency and hardness, its coating film is prone to discoloration.
