Description
Technical field
The invention belongs to artworks to handle industrial technology field, and in particular to a kind of bamboo wood it is protective agent used.
Background technique
Bamboo is tall and big, the rapid grass kind plant of growth, and stem is wooden.It is distributed in the torrid zone, subtropical zone to warm temperate zone area,
It is distributed on East Asia, Southeast Asia and the Indian Ocean and Pacific Islands and most concentrates, type is also most.Bamboo branch bar is tall and straight, slender, Chinese holly
Kingfisher, the proud rain of Ling Shuan, is liked by Chinese people, there is the laudatory titles such as " plum blossom, orchid, bamboo and chrysanthemum " four gentleman, " Mei Songzhu " three durable plants of winter: pine, bamboo and plum blossom.It is Chinese ancient
The modern men of literature and writing, it is numerous that thermophilic bamboo chants bamboo person.The chemical component of bamboo wood are as follows: cellulose 40% ~ 60%, hemicellulose 14% ~ 25% or more
More, lignin 16% ~ 34% has the tendency that increasing with the age.Extract: cold water leaching 2.5% ~ 5%, hot water leaching 5% ~ 12.5%,
Alcohol-ether leaches 3.5% ~ 5.5%, and alcohol-benzene leaches 2% ~ 9%, 1% leaching with sodium hydroxide 21% ~ 31%.In addition there are albumen 1.5% ~
6%, fatty glue cured 2% ~ 4%, starch 2% ~ 6%, reduced sugar about 2%, nitrogen 0.21% ~ 0.26%, ash content 1% ~ 3.5%.Phosphorous, potassium of institute etc.
Total amount reduce year by year, and silicon then has increase, siliceous cell is accumulated in, up to 4.35% or more in bamboo blueness.
Bamboo handicraft article refers to the craftwork of the artistic creations such as being carved, painted using bamboo as raw material.Bamboo art with
General log art ware is different, and after bamboo handicraft article is dried by boiling, service life is far more than timber products.Bamboo handicraft article
The bamboo wood used needs to handle by fungus-proof antisepsis before processing, and existing fungus-proof antisepsis inorganic agent not only hold time it is short,
And it is merely able to effect and surface layer, in the biggish situation of ambient humidity, anti-mold effect sharply declines.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of the protective agent used of bamboo wood is provided, what is be prepared is anti-
Mould inorganic agent can form firm chemical bond with bamboo wood, infiltrate into deep tissues, reduce its leachability, improve mould proof processing
The long-term effect of agent.
The present invention is achieved by the following technical solutions:
