Description
First, technical field：
The invention belongs to particieboard and preparation method thereof technical fields, and in particular to one kind is remaining residual after being extracted with Chinese herbal medicine
Slag and biomass protein adhesive are environment-friendly type shaving board prepared by raw material, i.e., present invention relates particularly to a kind of environment-friendly type shaving boards
And preparation method thereof.
2nd, background technology：
Formaldehyde is generally acknowledged carcinogen, and domestic and international scientific research has confirmed, formaldehyde can be drawn by regulating DNA expression
It plays the apoptosis of cell, oxidative damage is caused to large biological molecule (protein, DNA), cause cell carcinogenesis.At present, it is domestic raw
The particieboard overwhelming majority of production remains free formaldehyde.The main source of free formaldehyde has：I. manufacture particieboard generally uses
Lauxite can still remain unreacted free formaldehyde using formaldehyde as primary raw material in Lauxite；Ii. the unstable base of resin
Group can release formaldehyde during hot pressing or use；Iii. the hemicellulose in timber gradually decomposites formaldehyde.Particieboard is residual
The health of free formaldehyde meeting harmful to human stayed, it is therefore desirable to reduce the content of formaldehyde.
Many researchs and production show mainly to reduce particieboard by improving production and the application of Lauxite at present
Content of formaldehyde.Such as：By the way that urea is fed in batches, changes molar ratio, adjust the temperature, pH value and making sheet hot pressing of reaction
Condition etc..Although the molar ratio for reducing formaldehyde/urea in Lauxite production is most efficient method, this be easy to cause glue
Molecular structure changes, and bonding property declines.And by reducing the ratio of Lauxite, addition improves plank physical property
Melamine Production particieboard, the particieboard cost that this mode produces is compared with common plate height, and appearance is poor, and plate face Huang partially is not
Beauty, remaining free ammonia also be easy to cause secondary pollution.
Particieboard density is generally in 600-700 kilograms/m3, thickness is widely used in furniture system by 4mm to 40mm etc.
Make, speaker, consolidated floor, interior decoration wallboard, be important construction material.
With the progress of science, people’s lives level is gradually increased, and the thing followed is the increasingly severe of living environment,
Especially in modern house life, since the abuse of ornament materials causes a large amount of poisonous and harmful substances to be made one with the breathing of people
Suffer from various diseases.Existing household plank is glued substance usually using glued board etc. and is processed, and causes inside
Colloid containing formaldehyde gradually infiltrates into over time influences people's health in air.The method that people take precautions against it
It is to be adsorbed by the material PARA FORMALDEHYDE PRILLS(91,95) with adsorption function such as extraneous activated carbon, but its absorption needs a very long mistake
Journey causes indoor needs to divulge information for a long time during formaldehyde is eliminated and should not live.
With the raising that people recognize Chinese traditional culture, the Chinese medicine traditional Chinese medical science is increasingly taken seriously, the extraction of Chinese medicine
Technology is more and more perfect, and various Chinese patent drugs, the demand of traditional Chinese medicine oral liquid are increasing.Traditional Chinese medicine extraction enterprise is to integrated scale
Change fast development, so as to meet the needs in market.But a large amount of Chinese medicine residue is brought simultaneously, these residues shed agriculture
Field, burning can all bring pollution problem.Thus it is smelly to be deposited in the fermentation of traditional Chinese medicine extraction factory for a large amount of residues.These residues are most of
It is rattan, stem, wooden class, main component stem wood fibre.
Therefore, as people are to ornament materials environmental protection index increasingly higher demands, research and development content of formaldehyde it is as low as possible or
The plank of zero content of formaldehyde is very important.Meanwhile it is economic and environment-friendly handle Chinese medicine residue, avoid wasting and pollute, meet
The trend of the sustainable Green Development of Chinese medicine downstream industry.
3rd, invention content：
The technical problem to be solved by the present invention is to：A kind of environment-friendly type shaving board and preparation method thereof is provided.The technology of the present invention
Scheme prepares environment-friendly type shaving board, prepared product plane using the dregs of a decoction after traditional Chinese medicine extraction and biomass protein adhesive as raw material
The indices of card meet the quality standard of existing particieboard, and formaldehydeless release, while also there is certain health care to make
With.
To solve the above-mentioned problems, the technical solution adopted by the present invention is that：
The present invention provides a kind of environment-friendly type shaving board, is represented with parts by weight, the environment-friendly type shaving board primary raw material composition
