Embodiment 1

[0011] Cut the wooden material into a sample of 100mm×100mm. Then, clean the dust on the surface and sides of the material with a soft cloth, and place it in a vacuum film coating machine (model: DMJ-L II type). The solid waterproof material dichloroparylene (parylene C type) Vacuum degree 1.33×10 -5 Mpa, at a temperature of 110°C, it is evaporated into a gaseous state, and then, the gaseous dichloroparylene is in a vacuum of 1.33×10 -5 Mpa is cracked at a temperature of 680°C, and deposited on the surface of woody materials in the settling chamber to aggregate and crystallize. The vacuum degree of the deposition chamber is 1.33×10 -5 Mpa, the temperature is 25°C, and the vapor deposition time is 4 hours, the waterproof material forms a waterproof layer of dichloroparylene film with a thickness of 1~5um on the surface of the wooden material.

Embodiment 2

[0013] Cut the wooden material into a sample of 100mm x 100mm wide. Then, clean the dust on the surface and sides of the material with a soft cloth, and place it in a vacuum film coating machine (model: DMJ-L II type). The solid waterproof material dichloroparylene (parylene C type) Vacuum degree 1.33×10 -5 Mpa, at a temperature of 120°C, it is evaporated into a gaseous state, and then, the gaseous dichloroparylene is in a vacuum of 1.33×10 -5 Mpa is cracked at a temperature of 680°C, and deposited on the surface of woody materials in the settling chamber to aggregate and crystallize. The vacuum degree of the deposition chamber is 1.33×10 -5 Mpa, the temperature is 25°C, and the vapor deposition time is 3.5 hours, the waterproof material forms a waterproof layer of dichloroparylene film with a thickness of 1~5um on the surface of the wooden material.

Embodiment 3

[0015] Cut the wooden material into a sample of 100mm x 100mm wide. Then, clean the dust on the surface and sides of the material with a soft cloth, and place it in a vacuum film coating machine (model: DMJ-L II type). The solid waterproof material dichloroparylene (parylene C type) Vacuum degree 1.33×10 -5 Mpa, at a temperature of 130°C, it is evaporated into a gaseous state, and then, the gaseous dichloroparylene is in a vacuum of 1.33×10 -5 Mpa is cracked at a temperature of 680°C, and deposited on the surface of woody materials in the settling chamber to aggregate and crystallize. The vacuum degree of the deposition chamber is 1.33×10 -5 Mpa, the temperature is 25°C, and the vapor deposition time is 3 hours, the waterproof material forms a waterproof layer of dichloroparylene film with a thickness of 1~5um on the surface of the wooden material.

Abstract

The present invention is a moisture-proof method for coating the surface of wooden materials. The process steps are as follows: 1. cleaning the surface of the wooden material; 2. placing the wooden material after the surface cleaning treatment in a vacuum coating machine; The waterproof coating material is evaporated into a gaseous state in the evaporation chamber, and then enters the cracking chamber, where it is cracked into active monomers with reactive characteristics; this active monomer is gradually deposited on the surface of the wood material in the deposition chamber to aggregate and crystallize; forming a thickness of 1~5um Highly cross-linked pinhole-free polymer film waterproof membrane layer. Advantages: reduce the deformation of wood materials after moisture absorption, and greatly improve the waterproof and moisture-proof performance of materials. Maintain the unique color, mechanism and performance of the wood itself, improve the moisture-proof, mildew-proof, anti-corrosion, and moth-proof properties of the material, and use wood resources more effectively.

Description

technical field [0001] The invention relates to a moisture-proof method for coating a wooden material surface. The utility model belongs to the technical field of moisture-proof and water-proof of wooden materials. Background technique [0002] As a bioorganic material, wood is destroyed by climatic and biological factors in the environment. Wood is a porous material, with large pores such as cell lumens and pits, and small pores such as microfibril gaps. Moreover, wood contains many hydrophilic groups, making it easy for water to penetrate into the interior of the wood. These components are combined in the form of chemical bonds or hydrogen bonds, causing the swelling of the fibrils, thereby changing the size of the wood, that is, the shrinkage and swelling properties of wood. More importantly, wood is an anisotropic material, which swells and shrinks unevenly with changes in wood moisture content in all directions, and is prone to defects such as warping, deformation, an...
