Description

A kind of preparation method of fire-retardant Reclaimed board

Technical field

The present invention relates to the preparation method of a kind of fire-retardant Reclaimed board, belong to paper manufacturing technology field.

Background technology

Recycled writing paper is that waste and old books and newspapers, the carton etc. utilizing salvage station to purchase re-start processing, makes useful paper, thus makes refuse be utilized, decreases the waste of resource.But, recycled writing paper, due to shorter than the fiber of magma paper, is easily broken off so that it is range is restricted, and carton is thicker due to paper board material used, it is not necessary to repeatedly fold, and is that recycled writing paper applies a more field.

But there is disaster hidden-trouble in the links such as logistic storage in the regeneration carton without flame-retardant nature, therefore using flame retardant type packing board material is one of major measure reducing fire risk, existing fire-retardant carton, mostly is in non-flame-retardant material one layer of fire retardant of coating, and flame retardant effect is the best.

Summary of the invention

The technical problem to be solved is the defect overcoming prior art, it is provided that the preparation method of a kind of Reclaimed board, it is possible to increase the intensity of recycled writing paper and pliability, and has good flame-retardant nature.

For solving above-mentioned technical problem, the preparation method of a kind of fire-retardant Reclaimed board, comprise the following steps:

S1. the preparation method of corrugating media is regenerated: with slurry by carrying out after impurity elimination, the regenerated paper pulp of filtration treatment and process of plant fiber pulp mix, alginate is added during with slurry, again through manufacturing paper with pulp, suction press dehydration, low temperature drying, cut paper, prepare regenerative raw materials paper, regenerative raw materials letterweight is sanctioned and is cut into corrugating media;

S2. the preparation method of flame-retardant panel paper: putting in banbury by flame-proof polylactic acid polymer, organic phosphate starch-polyurethane and calcium carbonate raw material, high temperature banburying creates papermaking master batch;Papermaking master batch is put into casting machine and makes membranaceous, after redraw, cool down and shape, flatten, make fire-retardant raw material paper, fire-retardant raw material paper be cut into panel paper;

S3. cardboard is combined: is glued together with panel paper adhesive agent the top and bottom of corrugating media, to obtain final product.

The ratio of described regenerated paper pulp and process of plant fiber pulp is 60:40.

Described process of plant fiber pulp is the herbaceous plant fibre pulps such as reed, bagasse, wheat straw, straw.

Described drying temperature is less than 110 DEG C.

Described alginate is Manganese Alginate, the one of alginic acid cobalt or mixing.

Described adhesive is made up of rosin, carboxymethylcellulose calcium, tetradecyl methylacrylate, polyvinyl alcohol, emulsifying agent, water, NaOH, dispersant, tea oil.

The beneficial effect that the present invention is reached:

The present invention uses regenerated paper pulp to mix the paper making raw material as corrugating media with process of plant fiber pulp, compared with the mode of tradition magma papermaking, decrease the use of plant resources, with pure regenerated paper pulp as compared with the product of raw material, improve the content of paper product medium-length fibre, make the pliability of recycled writing paper and be slightly greatly improved;Adding alginate during with slurry, alginate has degradability, biocompatibility and the anti-flammability of excellence so that obtained corrugating media has certain fire resistance.

Use flame-proof polylactic acid polymer, organic phosphate starch-polyurethane and calcium carbonate as panel paper material, PLA is a kind of biodegradable polymer material deriving from renewable crops, nontoxic non-stimulated, degradable, itself fire resistance is poor, but can carry out flame-retardant modified by PLA carries out the modes such as halogen system, phosphorus system, nitrogen system, silicon system, metal compounds flame retardant, multiple flame-retardant composition be compounding;And organic phosphate starch-polyurethane material is by the Phosphation modification to starch, and with organic phosphate starch as reactive flame retardant, synthesize and both have biodegradation character, has again the polyurethane of flame-retarding characteristic, the material that both has degradable and flame-retarding characteristic mixes with calcium carbonate, the raw material paper prepared has good degradable and flame-retarding characteristic, both the deficient problem of resource of traditionally on paper material had been solved, solve again the disaster hidden-trouble problem in use, and do not result in the secondary pollution to environment.

Therefore, the preparation method of a kind of fire-retardant Reclaimed board provided by the present invention, prepared Reclaimed board, there is good pliability and intensity, and there is splendid flame-retarding characteristic, be suitable as carton packing material and use.

Detailed description of the invention

The invention will be further described below.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.

The preparation method of a kind of fire-retardant Reclaimed board, comprises the following steps:
