A kind of wood high-efficiency permeable silicone waterproofing agent and preparation method thereof

Abstract

The invention relates to a high-efficiency permeable type organosilicon waterproofing agent for wood and a preparation method thereof, which is characterized in that: it is prepared from the following raw materials: 30-40% of silicone resin prepolymer, 35-40% of a mixture of hydroxy silicone oil and dimethyl silicone oil %, organosilicon crosslinking agent 5~10%, long chain alkyl silane 5~10%, organosilicon quaternary ammonium salt 1~2%, pH adjusting organic solution 1~2%, auxiliary agent 2~10%, nanofiller 2-5%; the silicone resin prepolymer is a propyl and octyl silicone resin copolymer, and the percentages are all mass percentages. The high-efficiency penetrating type organosilicon waterproofing agent for wood of the invention has the advantages of non-toxicity, non-polluting, non-corrosiveness, does not change the original appearance of wood, and has the advantages of low price and the like. Applying the waterproofing agent of the present invention to the surface of wood can provide long-term waterproof protection to the wood.

Description

technical field [0001] The invention relates to the technical field of wood waterproofing, in particular to a wood highly permeable silicone waterproofing agent and a preparation method thereof. Background technique [0002] Wood waterproofing agents have been developed in the United States and other countries for nearly 60 years. Although my country has a long history of using tung oil to treat wood for waterproofing in ancient times, the use of more effective waterproofing agents for wood waterproofing is still in its infancy. At present, the waterproofing agents used for wood on the market include paraffin wax emulsion, methyl silicate waterproofing agent, fluorine-based waterproofing agent, etc., but there are certain shortcomings, such as paraffin wax emulsion, due to the small chemical bond energy, the overall waterproof performance and durability poor performance; methyl silicate waterproofing agents such as potassium methyl silicate with strong alkalinity will affect...

[0002] Wood waterproofing agents have been developed in the United States and other countries for nearly 60 years. Although my country has a long history of using tung oil to treat wood for waterproofing in ancient times, the use of more effective waterproofing agents for wood waterproofing is still in its infancy.

At present, the waterproofing agents used for wood on the market include paraffin wax emulsion, methyl silicate waterproofing agent, fluorine-based waterproofing agent, etc., but there are certain shortcomings, such as paraffin wax emulsion, due to the small chemical bond energy, the overall waterproof performance and durability poor performance; methyl silicate waterproofing agents such as potassium methyl silicate with strong alkalinity will affect the appearance of wood after use; and fluorine waterproofing agents (fluorine silicon, fluorocarbon) not only have a great impact on the environment during the production process, but also Poor permeability and very expensive
