Description

A kind of coating composition for improving reconstituted tobacoo bulk
Technical field
Patent of the present invention is applied to tobacco sheets by paper making method manufacture field, more particularly to one kind can improve reconstituted tobacoo bulky The coating composition of degree.
Background technology
In the production process of medicated cigarette, the waste materials of many can be produced, including can be with the cabo of recycling, low-quality Nicotiana tabacum L., offal and flue dust.In order to using these waste materials, mainly these waste materials are processed into character is close to natural tobacco to prior art The reconstituted tobacoo of leaf, then these reconstituted tobacoos are cut into into tobacco shred, it is back to production of cigarettes.At present, the production main flow of reconstituted tobacoo Using paper process, this method be first raw material soaking after, by soluble substance and insoluble thing extract and separate, insoluble thing one As can mix beating with wood pulp cellulose chip base, and soluble substance extract are obtained through the prepared coating of concentration charging using paper machine, Be applied on chip base using special coating method, reconstituted tobacoo is made through drying, then cut into tobacco shred.
Bulk is to evaluate the important technology index of tobacco sheets by paper making method.Bulk is improved, and thin slice is in coating to extraction The absorbability for taking coating also accordingly can be improved;In addition, bulk can also improve fillibility and burning of the reconstituted tobacoo in Medicated cigarette When flammability, reduce the harmful substance such as carbon monoxide.At present, the approach for improving reconstituted tobacoo bulk mainly adds precipitation Calcium Carbonate, but winnofil can hinder interfibrous combination, reduce the strength character of reconstituted tobacoo.
The content of the invention
The present invention is directed to problems described above, it is proposed that a kind of coating composition of raising reconstituted tobacoo bulk, including Tobacco extraction liquid and filler two parts.
A kind of coating composition for improving reconstituted tobacoo bulk, including following raw material:

Described nano-calcium carbonate Microcapsules Size is 1-3 microns, is coated with one layer on the hydroxyethyl cellulose surface The degree of polymerization of thickness 1-5 nanometers is 3000~10000 glucose molecule thin layers.
The ratio of the core and wall material of described nano-calcium carbonate microcapsule is (75-85):(15-25).
The dispersant is sodium polyacrylate, number-average molecular weight 3500-4000 of the sodium polyacrylate, and viscosity is 2250-2300mPa.s。
Described tobacco extraction liquid can be by using chemical drugss method or cold/hot water direct method, to Nicotiana tabacum L., cabo, broken cigarette One or more raw material in piece or offal is extracted, then Jing normal pressures or vacuum concentrate methool are obtained.
The dry composition of described tobacco extraction liquid accounts for the 30%-50% of coating fluid quality.
The coating composition for improving reconstituted tobacoo bulk provided by the present invention, operating procedure during use are as follows:
Tobacco not tolerant Jing after water extraction is manufactured paper with pulp molding, reconstituted tobacoo original piece is made;
By the coating composition for improving reconstituted tobacoo bulk reconstituted tobacoo original piece immersion of the present invention, during immersion Between be 3min, dipping when coating is disperseed using ultrasound wave, ultrasonic power be 22-25 KHz, be dried, cut, Obtain reconstituted tobacoo.
Compared with prior art, the invention has the beneficial effects as follows:
1. winnofil is replaced with nano-calcium carbonate microcapsule, be preferably fused to paper surface, improve surface not Planarization, maintains the intensity of reconstituted tobacoo, improves the bulk of reconstituted tobacoo.
2. nano-calcium carbonate disperses uneven as cloth filler is applied in coating fluid preparation process as which is Nano grade It is even to cause to reunite, microcapsule structure is made, is not only disperseed beneficial to which, moreover it is possible to improve its effectively retention, by super The effect of sound wave, ruptures can cyst wall, discharge nano-calcium carbonate, play the effect for improving paper surface evenness.
3. Microcrystalline Cellulose is added in coating, strengthen be combineding with each other between composition in paper, increase paper strength;And it is micro- The cellular structure of crystalline cellulose, is conducive to absorption and reservation to extract composition, and also the bulk for page is made that tribute Offer.
4. the degree of polymerization for being coated with a layer thickness 1-5 nanometer on the hydroxyethyl cellulose surface is 3000~10000 Glucose molecule thin layer, forms hydrogen bonded with Microcrystalline Cellulose, improves the stability of coating composition.
