Description
Technical field
The present invention relates to stone paper preparing technical field, and in particular to a kind of preparation method of light-high-strength stone paper.
Background technology
With the continuous enhancing of global low-carbon environment-friendly consciousness, people are directed to researching and developing environmentally protective material more and more
Material, stone paper at home and abroad gradually receive attention and development as a kind of novel environment friendly synthetic paper.The primary raw material of stone paper
For a large amount of stone powder, a small amount of resin and some auxiliary agents, through by these primary raw materials and mixing, is modified, being granulated, extruding, stretching
Stone paper is can be made into etc. technique.Stone paper have tensile strength is big, folding damage resistibility can it is good, tearing strength is high, water-fast, resistance to
Oil, chemical resistance protrude, non-aging, be not afraid of the excellent performance such as damage by worms, and all determine that stone paper is led in packaging material
Domain possesses more wide application space.
Go into operation currently on the market and promoted the use of stone paper, it is in journalism field, cultural paper, map, wall
Paper etc. has obtained preferable application, but according to the analysis of manufacturer, the weight ratio common plant of stone paper is fine at present
Dimension paper is big by 30%~50%, and which greatly limits the application range of stone paper.
In addition stone paper is one kind with organic polymer（Mainly polyolefin）It is primary raw material with inorganic filler, addition is few
Measure synthetic paper made of adjuvant.And cause stone paper there are the problem of poor compatibility between inorganic filler and organic polymer

Ammonium oxalate, stirs 10~15min；
（4）Treat enclosed high pressure water heating kettle after above-mentioned stirring, heat temperature raising, hydro-thermal reaction, is separated by filtration and is precipitated, will be heavy
Shallow lake is put into Muffle furnace, and 400~600 DEG C, 2~4h of heat preservation sintering, during discharging obtains are heated to the speed of 20 DEG C/min
Empty nano hydrotalcite powder；
（5）After above-mentioned hollow nano hydrotalcite powder and ellagic acid, ursin, Rosa Damascana, dusty yeast and water are mixed
To mixed liquor, mixed liquor is fitted into fermentation tank, is sealed by fermentation, is separated by filtration to obtain fermentation filter residue, it is dry, obtain modified hollow
Nano hydrotalcite powder；
（6）Count in parts by weight, weigh the hollow nano hydrotalcite powder of 60~70 parts of above-mentioned modifications, 20~30 parts of polyethylene, 0.3
~0.5 part of neopelex and 3~5 parts of azodicarbonamides are added in kneading machine, are kneaded, are obtained batch mixing, will be upper
State batch mixing and move into extruding pelletization in double screw extruder, and cut, repaiied with 60~70 DEG C of temperature calendering formation with calender
Side, up to light-high-strength stone paper.
Step（1）Described in stalk crushed material and mass fraction be 30% sodium hydroxide solution and absolute ethyl alcohol
Mass ratio is 1:5:5.
Step（2）Described in mixed solution and mass fraction be 30% ammonium hydroxide and the mass ratio of potassium carbonate be 10:1:
1。
Step（3）Described in polyhydroxy fibre bundle addition be pre-reaction liquid quality 10%, the addition of potassium rhodanate
Measure as the 1% of pre-reaction liquid quality, the addition of ammonium oxalate is the 1% of pre-reaction liquid quality.
Step（4）Described in the pressure of hydro-thermal reaction be 1.5~1.8MPa, the temperature of heat temperature raising is 170~180
DEG C, the hydro-thermal reaction time is 25~30h.
Step（5）Described in hollow nano hydrotalcite powder and ellagic acid, ursin, Rosa Damascana, dusty yeast and
The mass ratio of water is 10:3:2:2:1:50, drying temperature is 105~110 DEG C, and drying time is 1~2h.
Step（6）Described in melting temperature be 70~80 DEG C, mixing time is 5~10min.
The beneficial effects of the invention are as follows：The present invention carries out boiling by alkali and absolute ethyl alcohol to stalk crushed material first, carries
High microsteping plasticity and to fiber carry out hydroxylating modification, followed by ice split effect coordinate ball milling obtain polyhydroxy fibre bundle, with
Polyhydroxy fibre bundle produces nanoscale hydrotalcite particles by hydro-thermal method and is attached to polyhydroxy fibre bundle as deposition kernel template
Template surface, and addition potassium rhodanate and ammonium oxalate, ammonium oxalate are thermally decomposed into oxalic acid and ammonia first while hydro-thermal reaction
Gas, under the action of potassium rhodanate so that the metal ion in hydrotalcite leaves original lattice position and enters oxalic acid organic phase,
So as to produce hole on hydrotalcite lattice, the adsorption activity of hydrotalcite is improved, finally calcining removes polyhydroxy fibre bundle kernel, obtains
To the hollow nano hydrotalcite of high adsorption activity, the nano hydrotalcite of high adsorption is improved the absorption property of polyethylene,
So that both bond strengths are improved, in addition under the action of oxalic acid, the metal ion in hollow hydrotalcite is partially activated,
Active function groups on the metal ion and polyethylene molecule of these activation form metal coordinate bond, further improve inorganic filler
Bond strength between polymer, improves compatibility between the two；
（2）The present invention also to hollow nano hydrotalcite carried out fermentation be modified, using microorganism will be enriched in Polyphenols ellagic acid,
Ursin, Rosa Damascana are degraded, and produce a large amount of free property aryls and ester group, and by the effect of microorganism by aryl
Nano hydrotalcite surface is incorporated into ester group, due to the introducing of nonpolar aryl so that nano hydrotalcite and nonpolar poly-
There is similar chemical attribute, so as to improve compatibility between the two between compound；
（3）The present invention instead of common mountain flour with hollow nano hydrotalcite and prepare stone paper, hollow powder use so that
Stone paper has lighter weight in the case of same volume, has reached the light requirement of stone paper, has widened stone paper
Application field, and hydrotalcite can decompose when burning is heated and absorb comburant surface heat to fire retardation, release at the same time
The oxygen on large quantity of moisture dilution combustion things surface is released, decomposes the activated magnesia of generation, Alumina build-up in combustible surface again
Further prevent the progress of burning, and it is whole it is fire-retardant during not only produced without any harmful substance, and its point
The product of solution can also largely absorb pernicious gas and smog caused by high molecular polymer burning fire-retardant while, constantly
Imperfect combustion fusing residue is absorbed, from elimination smog, prevention molten drop while burning is stopped quickly so that the present invention
Stone paper there is splendid flame retardant effect.
