Description
The application is application number：2016108508711, the applying date：On 09 27th, 2016, denomination of invention：A kind of papermaking
With the divisional application of the preparation method of compounded mix.
Technical field
The invention belongs to field of papermaking, and in particular to a kind of preparation method of paper grade (stock) compounded mix.
Background technology
Eggshell is a kind of common life waste material, is easy to get and cheap.The processing and utilization degree of eggshell is but very low, most of quilt
It is lost as solid waste, remaining egg white and egg shell membrane can be putrid and deteriorated quickly in these eggshells, not only pollute environment,
Cause the waste of eggshell resource.Cinder is a kind of common industrial solid wastes, and substantial amounts of cinder is thrown aside accumulation, do not only taken up
Soil releases sulfurous gas pollution air, endangers environment；Reasonable utilize of cinder is that solid waste processing urgently to be resolved hurrily is asked
Topic.
Egg-shell meal is through centainly handling obtained inorganic powder material after discarded eggshell is crushed.Calcium carbonate in egg-shell meal
Content can be used for making papermaking filler, but egg-shell meal directly is used as papermaking filler can cause to be filled with paper more than 90%
Optical property is poor.The whiteness of cinder powder itself is also lower than the whiteness of egg-shell meal, directly affects the optical property of filled paper.
The content of the invention
It to solve the above-mentioned problems, can not only effective land productivity the object of the present invention is to provide a kind of paper grade (stock) compounded mix
With discarded object eggshell and cinder, the optical property for being filled with paper can also be greatly improved.
To achieve the above object, the present invention provides a kind of preparation method of paper grade (stock) compounded mix, and this method includes following
Step：
Step 1：Eggshell is cleaned into rear natural air drying, the organic matter being attached to using aqueous slkali soaking removal on eggshell surface, instead
Multiple rinse is placed on freeze-day with constant temperature 4-6h at 105-120 DEG C；Ball mill ball milling 3-5h is used after eggshell is ground into fritter, obtains eggshell
Powder；With ball mill ball milling 20-30min after cinder is dried, cinder powder is obtained；
Step 2：By egg-shell meal, cinder powder and water resistant, high temperature resistant binder according to a certain percentage after mixing, it is heated solid
It is crushed after change, obtains bonding powder；
Step 3：Bonding powder is taken to add in a certain amount of dispersant stirring after being configured to the suspension of mass concentration 10-20%
Even, TiO 2 sol is slowly added dropwise in the suspension into stirring, and suspension is heated and continues to stir, be washed out, filter,
It dries, compounded mix is obtained with 400-500 DEG C of calcining 3-5h, last ground, 300 mesh sieves excessively in Muffle furnace.
Aqueous slkali described in step 1 is the sodium hydroxide solution that mass concentration is 5%.
Water resistant, high temperature resistant binder described in step 2 is alumina silicate-zirconium oxide adhesive.
The number of egg-shell meal, cinder powder and water resistant, high temperature resistant binder each component described in step 2 is：Egg-shell meal 60-
80 parts, 10-30 parts of cinder powder, 5-20 parts of water resistant, high temperature resistant binder.
Dispersant described in step 3 is polyethylene glycol, and the amount of dispersant is the bonding powder gross mass of addition
0.3%。
The principle of the present invention is：Since the time that cinder is under equal conditions ground is more shorter than eggshell, obtained coal
Ground-slag is bigger than the grain size of egg-shell meal；By egg-shell meal, cinder powder and water resistant, high temperature resistant binder after mixing, thinner eggshell
The more bonding of powder energy is on cinder powder surface, and the whiteness of egg-shell meal is higher than cinder powder, therefore, the bonding powder being grinding to obtain
Whiteness it is higher than the whiteness of cinder powder itself, improve whole whiteness；When compounded mix whiteness to be achieved is the same, reduce
The usage amount of titanium dioxide.
Beneficial effects of the present invention：The present invention uses discarded object eggshell and cinder to prepare paper grade (stock) compounded mix for raw material,
The solid pollution that discarded eggshell and cinder are brought can effectively be solved；Egg-shell meal, cinder powder and water resistant, high temperature resistant binder are mixed
After closing uniformly, it is heated cure, crush in obtained bonding powder egg-shell meal can more bonding on cinder powder surface, improve
Whole whiteness and specific surface area, reduces the dosage of titanium dioxide, while improves by the probability of coated by titanium dioxide, obtains
Compounded mix optical property it is more preferable；Compared with the papermaking fillers such as traditional calcium carbonate, talcum powder and kaolin, of the invention
To compounded mix be added to when being applied as papermaking filler with more excellent optical property, filler in paper, paper
The improvement effect of Zhang Baidu and opacity is notable.
