Description
Technical field
The present invention relates to a kind of modified talc powder for filler interpolation and preparation method thereof, belong to Pulvis Talci chemical industry
Making field.
Background technology
Pulvis Talci is the lyophobic dust that a kind of white is soft, belongs to natural monoclinic system hydrosilicate, by 31.7 %
Magnesium oxide, the silicon dioxide of 63.5 %, 4.8 % water composition, molecular formula is 3MgO 4SiO2 H2O.Pulvis Talci typically so that
Close bulk, foliaceous, radial, fibrous agrregate form exist, and outward appearance is water white transparency or white, but because of containing a small amount of
Impurity and present palm fibre even light red light green, pale yellow, shallow.Due to its there is lubricity, anti-glutinous, covering power good, soft, gloss
The excellent Wuli-Shili-Renli system approach such as good, high temperature resistant, Pulvis Talci has obtained extensively in industries such as cosmetics, medicine, papermaking, coating
Application.China's Pulvis Talci annual production is at about 2,450,000 tons at present, mainly originates from the provinces and regions such as the Liao Dynasty, Shandong, osmanthus.On the whole, I
State's low grade Talcum is still in the situation that supply exceed demand, but the production capacity that top grade whitens stone raw material is far smaller than domestic and international market
Demand, thus high-grade Talcum supply is by long-term breach.Therefore, expand the deep processing of low-and-medium-grade products, exploitation high added value
Product is critically important.
Pulvis Talci modification has multiple method, and it is that surfactant or coupling agent are covered in particle table that surface covers modified method
Face, makes surfactant or coupling agent be combined with particle surface in the way of absorption or chemical bond, makes particle surface by hydrophilic change
For hydrophobic, give the character that particle is new, make particle be improved with the compatibility of polymer.The method is the most commonly used
Method.Substantially can be regarded as: for the shortcoming that Pulvis Talci and polymer affinity are the highest, is lived in the surface with amphiprotic group
Property agent cover on particle, hydrophilic group is towards particle surface, and lipophilic group, towards outside, so just had when polymer is combined
The compatibility, reach modified purpose, expand talcous range of application.
Pulvis Talci method of modifying is a lot, in addition to method mentioned above, also includes that Topically active modification, high-energy surface change
Property etc., Topically active modification utilizes chemical reaction, and in particle surface grafting, some can be with the group of polymer-compatible or sense
Group, makes inorganic particulate and polymer have the more preferable compatibility, thus reaches the purpose that inorganic particulate is compound with polymer.High-energy
Surface modification is to utilize the produced huge energy such as high-energy discharge, plasma ray, ultraviolet to improving particle surface so that it is
Surface is active, improves the compatibility of particle and polymer.
It is desirable to provide a kind of modified talc powder added for filler, its preparation technology is simple, Ke Yixian
Write the whiteness improving paper, and tensile index and burst index also improve.
Summary of the invention
The technical problem existed based on background technology, the invention provides a kind of modified talc added for filler
Powder, its preparation technology is simple, can significantly improve the whiteness of paper, and tensile index and burst index also have certain proposing
High.
Technical scheme is as follows:
A kind of preparation method of the modified talc powder added for filler, its step is as follows:
(1) by weight, 0.12-0.18 part carboxymethyl chitosan, 0.3 portion of trehalose, 0.2-0.5 part vitamin C, 0.2-are taken
0.3 part of instant CMC, 100 parts of water are prepared as aqueous solution at normal temperatures, are heated rapidly to 70 degrees Celsius and keep 30s, often return to
Temperature；
(2) by weight, adding 5 parts of Pulvis Talci, 50 parts of pure water, after being sufficiently stirred for making its mix homogeneously, by 0.05 part of step
Suddenly the solution that (1) prepares, continues to be thoroughly mixed 20min under 600r/m i n, and property adds 0.2 part of 2 wt% again
Adlerika and continue stir 5min, by scrubbed for modified talc powder suspension, filtration treatment；
(3) modified talc powder is dispersed in water again, by 150w microwave treatment 3min, both obtained.
The invention have benefit that:
The preparation technology of the present invention is simple, and preparation technology is simple, can significantly improve the whiteness of paper, and tensile index and resistance to
Broken index also improves.
