Description
Technical field
The present invention relates to low-grade recessed native deep processing and its as the processing method of Retention Aid in Papermaking, belong to nonmetallic mineral
Technical field of resource utilization.
Background technology
The nonmetallic minerals such as attapulgite, bentonite, kaolin, calcium carbonate, wollastonite, talcum have extensively in field of papermaking
General application, for example, Patent No. 200410049606.0, it is entitled " paper making mineral composite retention aid and preparation method thereof with
Using " disclose bentonite, calcite, wollastonite, sepiolite, attapulgite, zeolite and kaolin mineral are purified and calcined
Then grinding is uniformly mixing to obtain in a certain proportion of wollastonite of addition and sepiolite.Application No. is 201210013223.2, name
Referred to as " cationic compound retention agent of papermaking and its preparation method and application method " disclose by bentonite, calcite, wollastonite,
Sepiolite, attapulgite, zeolite, hydrotalcite and kaolin are mixed and are obtained after calcining and grinding.Application No. is
201410365287.8, entitled " Retention Aid in Papermaking and preparation method thereof " disclose by bentonite, calcite, attapulgite,
Wollastonite, talcum mixed grinding in proportion, with the pretreatment of chitosan, polyacrylamide and glacial acetic acid secure satisfactory grades subgroup point with it is above-mentioned
Mixture is further mixed to get in proportion.From above-mentioned three disclosures it is found that the retention agent of prior art preparation relates to
And the compounding of a variety of nonmetallic minerals, but do not consider complexity and the variability of natural non-metallic mine ingredient；Secondly the patent No.
200410049606.0 201210013223.2 two pieces patent requirements compound of number of patent application is through calcination processing（Destroy crystal
Structure）.Above three patent proposes that mineral compounding requires, and this patent proposes excellent using the natural built-up of low-grade recessed Tu Kuang
Gesture seeks the application to high added value for the tailing that low value is abandoned.
Invention content
Present invention aims at：A kind of method that low-grade recessed soil prepares Retention Aid in Papermaking is provided, can be filled by this method
The natural built-up advantage of recessed native each component is waved in distribution, is improved copy paper system and is promoted paper product performance, and recessed native application field is expanded.
Technical solution of the invention is：
The method that low-grade recessed soil prepares Retention Aid in Papermaking, it is characterised in that：The retention agent is with low-grade recessed native for major ingredient, by matter
Percentage is measured, wherein attapulgite content is 20-30%, and smectite content 10-30%, dolomite content is 10-30%, quartz
Or opal content≤10%, remaining is other type clays；Recessed Tu Kuang is carried out as needed first above-mentioned to reach with mine
Proportional region, then repeated water spray stand and two pairs of rollers extrusion process 3-4 time after, solarization dry doubling is crushed to 4.5 μm, add 5-10% sun from
Sub- starch or polyacrylamide stir evenly up to Retention Aid in Papermaking.
Other type clays are the mixing of one or more of kaolinite, chlorite, feldspar or magnesite.
When the retention agent is used for papermaking, dosage is the 3-5% of pulp weight.
The low-grade recessed soil refers to the recessed soil of dolomite type or bentonite that attapulgite content range is 20%-30%
The recessed soil of type, and content≤10% of quartz or opal.
Low-grade recessed native impurities are mainly montmorillonite and dolomite etc., they can be with water under certain process conditions
Dissolve from micro-and nano-particles are formed, the polynary particle that can be compounded with high molecular polymer needed for structure Modern High-Speed copy paper technique helps
System, the energy tiny plant fiber of effectively catching is stayed to significantly improve the high load capacity of the closing plain boiled water circulatory system；In addition, foreign particle
Shape and physicochemical property and attapulgite have complementarity in paper product filling, interweaving with plant fiber to form good filling and imitates
It answers, synergistic effect can effectively promote paper product performance.
The present invention is directed to make full use of the natural compound advantage of the low-grade recessed micro-nano component of soil；It is only to stablize retention with mine
Agent component ratio；Water mixing two pairs of rollers squeeze the micro-nano dissociation effect for realizing high performance-price ratio；It emphasizes to dry or low temperature drying is to keep
The physicochemical property of the micro-nano component of clay avoids calcining.
The advantage of the invention is that：Low-grade recessed soil is natural micro Nano material aggregate, is ideal fully after dissociation
The polynary microparticle retention aid of copy paper has stronger binding force, use that can show on plant fiber under the conditions of neutral or alkaline paper-making
It writes and improves tiny plant fiber retention and paper strength；The Retention Aid in Papermaking processing technology and equipment are simple, meet cleaning life
Production requires.The Retention Aid in Papermaking integrates three kinds of filling, retention and drainage functions, in energy-saving, clean manufacturing and promotion
The high-valued application of recessed soil is realized while paper product quality.
Specific implementation mode
With reference to specific embodiment, description is of the invention in further detail.It should be understood that these embodiments are intended merely to
