Abstract

The invention relates to a full-automatic stone papermaking production process. The production process sequentially comprises the following steps of: (1) preparing 75 to 80 percent of stone into stone powder, wherein the calcium carbonate content of the stone is over 93 percent; (2) screening the stone powder to meet the requirement of 1,000 to 1,500 meshes through a filter screening device; (3) performing modification treatment on the filtered stone powder through a drying and stirring device; (4) mixing and stirring the modified stone powder, 15 to 20 percent of plastic polypropylene (PP) or polyethylene (PE) or poly (hydroxybutyrate-hydroxyvalerate) (PHBV) and 4.5 to 5.5 percent of an auxiliary agent, automatically conveying the mixture to the funnel of a granulator after the stirring is completed, automatically starting double mixing screws through the granulator, performing extrusion and granulation, and feeding the granules into a charging barrel; (5) automatically conveying the formed granules into the funnel of an extruder, extruding the colloidal fluid to a wide die head through the extruder by high-speed rotation of single screw of a mixing device, extruding the colloidal fluid into sheets, cooling rollers to the required temperature through cooling circulating fluid in a three-roller calendering cold cutting tower, and stretching the sheets to form stone paper sheets of required thickness through a flow extension machine; and (6) automatically conveying the stone paper sheets to coating equipment, and performing automatic double-side coating.

Description

Full-automatic stone papermaking production technology

Technical field:

The present invention relates to a kind of paper production technology, refer in particular to a kind of full-automatic stone papermaking production technology.

Background technology:

Existing traditional various papermaking process, use wet production mostly, by complicated technology manufacturings such as a series of physical chemistry pulp treatment, consume resources such as a large amount of water, electricity, coal, plant, manpower, the cost height, technology is many, pollute and weigh destruction ecological environment, improvement difficulty, do not meet the requirement of present low-carbon environment-friendly, thereby can't satisfy the demand in market.Be directed to this, so the applicant designs the present invention.

Summary of the invention:

Technical problem to be solved by this invention just is to overcome above-mentioned existing deficiency, and providing a kind of is the full-automatic paper production technology of raw material with stone.

For solving the problems of the technologies described above, the technical solution used in the present invention is: this production craft step is followed successively by:

(1) stone of ratio 75%-80% is made the stone powder, wherein, the calcium carbonate content of stone is more than 93%;

(2) with the stone powder after filtration screening plant screen to the requirement of 1000-1500 order;

(3) the stone powder that filters being carried out modification through the super-dry agitating device handles;

(4) the stone powder after the modification processing is mixed stirring with the plastics PP of ratio 15%-20% or the auxiliary agent of PE or PHBV and ratio 4.5%-5.5%, stirred and sent into the comminutor funnel automatically, comminutor starts the banburying twin-screw automatically and extrudes pelletizing to cartridge;

(5) the grain automatic transport that will make is in the extruder funnel, extruder rotates at a high speed through banburying device list screw rod will be made gluey fluid and be extruded into wide film head extrusion sheet again, prolong cold cut tower cooler circulation fluid through three roll-ins and roller bearing is cooled to needed temperature will stretch through casting machine then and form the stone paper of desired thickness;

(6) the stone paper will enter coating apparatus automatically and carry out automatic double-sided coating.

In the technique scheme, described step (1): the stone of ratio 75%-80% is broken into the small stone of 3-5 centimetre, then small stone is sent into three ring maincenter pulverizing mills and worn into the stone powder, wherein, the calcium carbonate content of stone is more than 93%, requires abrasive dust screening fineness to reach the 1000-1500 order.

In the technique scheme, described step (1): the stone of ratio 75%-80% is carried out calcination, utilize abrasive dust equipment to wear into the stone powder then, wherein, the calcium carbonate content of stone is more than 93%.

In the technique scheme, described step (5): the grain automatic transport that will make is in the extruder funnel, extruder rotates the gluey fluid of making at a high speed through banburying device list screw rod and is extruded into wide film head extrusion sheet again, prolongs cold cut tower cooler circulation fluid through three roll-ins roller bearing is cooled to needed temperature forms desired thickness then through the casting machine stretching stone paper; Then the stone paper is carried out carrying out automatic winding after the automatic cutting, rim charge is reclaimed automatically.

In the technique scheme, described stone is one or more in calcite, lime stone, the marble.

Wherein,

PP is a polypropylene, and it is the another fine resin kind of development after nylon, it be a kind of high density, unprotected side chain, high crystallization must linear polymer, have excellent comprehensive performances.

PE is a polyethylene, its odorless, nontoxic, the feel ceraceous has good resistance to low temperature (minimum serviceability temperature can reach-70～-100 ℃), and chemical stability is good, the erosion of the most of soda acids of ability (not anti-acid) with oxidizing property, be insoluble to common solvent under the normal temperature, water imbibition is little, and electrical insulation capability is good.

PHBV is new bio macromolecule 3-hydroxybutyric acid-co-3-hydroxyl pentanoate copolymer, and it is a kind of biological polyester, and it is produced by bacterium, can be decomposed into carbon dioxide, water and living beings fully under soil or compost condition by bacterial digestion.

Advantage of the present invention is: the making production technology is simple, and production cost is low, the rate of return on investment height, and energy savings is protected national resource, and improving environment has very significant meaning.
