Description
Technical field
The present invention relates to a kind of methods using porous livestock and poultry bone machining function based plate, belong to environment-friendly sheet processing skill
Art field.
Background technique
Most of plates all make plate forming by way of hot pressing in the market, and hot pressing guarantees that slab is being heated and pressurizeed
In the case of be compressed to reservation thickness rapidly, and keep the temperature and dwell condition under so that adhesive solidifies, plate blank molding, and making
Partial moisture vaporization in slab is obtained, is discharged out of plate, energy consumption is high using the mode of hot pressing in this kind of plate preparation process, not ring
It protects.
For existing plate mostly using timber as raw material, growing plate demand results in excessive lumber consumption, thus
Cause a series of ecological environment problems, and that there are fire protecting performances is poor for wooden boards, hygroscopic dampness causes to deform, sound insulation value
It is bad, the problems such as static bending strength is not high.
Summary of the invention
A large amount of timber are needed to be that raw material destroys ecology to solve existing wooden boards, and that there are fire protecting performances is poor, hygroscopic
Dampness leads to problems such as deformation, sound insulation value bad, and the present invention provides a kind of preparation methods of novel environment friendly plate, specially
A method of utilizing porous livestock and poultry bone machining function based plate, fire prevention, waterproof, the sound insulation of the bone plate plate of this method processing
Existing wooden boards are superior to indexs such as static bending strength, the technical solution adopted is as follows:
The purpose of the present invention is to provide a kind of method using porous livestock and poultry bone machining function based plate, this method packets
Include following steps:
(1) it collects raw material: collecting any in the life bone of livestock, the ripe bone of livestock, the life bone of poultry and the ripe bone of poultry
One or more mixtures, and will it is raw bone boiling is ripe pulls out, discard the water containing grease and gelatine;
(2) preparation of raw material: the ripe bone and/or cooked life bone that step (1) is obtained carry out ungrease treatment, powder after drying
It is broken into bone meal and/or bone block, it is spare after sieving;
(3) bone meal and/or bone block obtained with step (2) is carried out glue mixing with adhesive and is uniformly mixed, and mould is subsequently placed in
In tool, physical compression is carried out to mold at normal temperature, is taken out after pressurization, dry blank flat.
Preferably, step (2) described ungrease treatment is to be immersed in the ripe bone of step (1) acquisition and/or cooked life bone
It in sodium hydroxide solution, places into hydrogenperoxide steam generator and impregnates after taking-up, with completing degreasing after clear water rinsed clean after taking-up.
It is highly preferred that the concentration of the sodium hydroxide is 5g/L;The concentration of the hydrogen peroxide is 30g/L.It is highly preferred that in hydroxide
Soaking time in sodium solution is 1 day~2 days;Soaking time is 4h-6h in hydrogenperoxide steam generator.Most preferably, in hydrogen-oxygen
Changing the soaking time in sodium solution is 2 days, and soaking time is 5h in hydrogenperoxide steam generator.
Preferably, the granularity of step (2) described bone block is not more than 2cm;The granularity of the bone meal is not more than 3mm.
Preferably, step (3) described physical compression is the pressure that physics applies 10MPa~20MPa, and the time of pressurization is
10min~30min.
Preferably, step (3) described drying is placed in natural air drying one day at outdoor ventilation.
Preferably, step (3) described adhesive is MS sealant or neoprene.
It is highly preferred that step (3) described adhesive is MS sealant;The bone after ungrease treatment is crushed in step (2)
At bone block, be then (2~4.8) according to the mass ratio of bone block and adhesive: 1 carries out glue mixing.The mass ratio of bone block and adhesive
Most preferably 2:1.
It is highly preferred that step (3) described adhesive is neoprene;Bone after ungrease treatment is ground by step in (2)
Then bone meal and broken bone block are that 1:3.6:1 carries out glue mixing according to the mass ratio of adhesive, bone block and bone meal.
The invention has the advantages that:
The invention proposes a kind of processing method of novel environment friendly plate, this method is replaced with the livestock and poultry bone of porous structure
Timber prepares plate as raw material, keeps novel environment friendly plate obtained wooden compared to existing using the distinctive porous structure of bone
Plate has better soundproof effect, and higher static bending strength is obtained under identical density, given full play to bone burning point it is high,
Not hygroscopic characteristic makes prepared plate, and better fire protecting performance overcomes existing wood not the advantages that moisture-sensitive deformation
Lumber need a large amount of timber be raw material need to destroy ecology, there are fire protecting performance differences inflammable, hygroscopic dampness causes deformation, every
The disadvantages of sound performance is bad, static bending strength is not high.
Processing method of the present invention proposes the method for anticorrosion treatment of a set of new livestock and poultry bone, and this method passes through lye and mistake
Hydrogen oxide Duplex treatment removes the degreasing method of the impurity such as marrow, is successively immersed in sodium hydroxide solution particular by by ripe bone
It neutralizes in hydrogenperoxide steam generator and completes degreasing, so that the basic without grease residual of bone surface, degreasing effect is good, and places half a year not
Moldy metamorphism effectively extends the service life of bone, and existing degreasing method is placed and occurred in 1 month in various degree
Signs of Mould.
In processing method of the present invention by the way of physical compression, this method has abandoned traditional hot pressing mode, avoids
The generation for the problems such as plate internal stress in hot pressing is excessive and cracks, both reduces energy consumption, in turn ensures poultry bone plate material
Performance is intact, and sheeting process is safer and easy without heating.
The present invention has the Animal Bone environment-friendly sheet of superperformance, existing wooden boards can be effectively substituted, to subtract
Few felling to timber, and realize the recycling and reusing to discarded bone, facilitate the sustainable development of environment.
