Abstract
The invention discloses a preparation method of a germicidal packing paper. The method specifically comprises the following steps of: (1) cutting raw materials into pieces; (2) boiling; (3) washing; (4) screening and purifying; (5) washing and concentrating; (6) pulping; (7) preparing a glue liquor applied in the pulp; (8) preparing a glue liquor applied on the surface; (9) fragmenting the pulp; (10) applying glue on the surface, wherein the glue liquor applied on the surface is selected from modified cassava starch and polyvinyl alcohol; and (11) preparing finished products by stretching and drying the pulp via a stretchable device. According to the invention, bacteria can be prevented from invading, and the prepared paper is good in air permeability and high in strength; and as ethylparaben dissolved by alcohol in the step of applying the glue liquor on the surface has good adhesion, water resistance, flexibility and glue protectiveness, the prepared paper has certain strength and bursting strength.
Description
Technical field
The present invention relates to a kind of production method of sterilization packaging paper, belong to the packing technique field.
Background technology
The sterilization packaging body paper is the basic paper of producing medical packing paper, it processes through string, the body paper of producing is as the medical package material, health and quality there is strict demand, when having certain air permeability, body paper must have good strength character, the wet intensity that rises particularly, it directly has influence on the safety and sanitation of medical apparatus, and more domestic products ubiquity on this index is defective.Now the body paper of Sheng Chaning generally passes through pulping, making beating, batching, upward net forming, top sizing, drying are batched to cut and formed, generally in the size degradation operation, select homemade or Russian product wood pulp for use, in size degradation liquid, do not add other industrial chemicals, what surface size used is to use converted starch, and tensile strength, wet rise intensity, tearability and permeability do not reach ideal effect.Cracky when carrying out disinfection or sterilizing by high-temperature steam can not play the effect that intercepts bacterium; If load medicine equipment and use ethylene oxide sterilizing with all-plastic packing, can produce sterilization not exclusively or gas residue in packaging bag, have certain poison residual, be difficult to reach the requirement of sterilization of medical instrument packing rule ISO11607EN868 international standard.
Summary of the invention
At the deficiency that prior art exists, the object of the invention provides a kind of production method that can intercept the sterilization packaging paper of bacterial invasion.
To achieve these goals, the present invention realizes by the following technical solutions:
The present invention specifically may further comprise the steps:
(1) raw material is chipped;
(2) boiling;
(3) washing;
(4) screening purifies;
(5) washing concentrating;
(6) making beating;
(7) plasm-glue-blending liquid preparation section;
(8) surface size preparation section;
(9) slurry size degradation operation;
(10) top sizing operation, surface size uses cassava modified starch and polyvinyl alcohol;
(11) make finished product through hyperextension device stretching drying.
Above-mentioned size degradation operation adds hardwood pulp, softwood pulp when size degradation, hardwood pulp: the weight ratio of softwood pulp is 1: 4.5～5.5.
Above-mentioned top sizing operation contains the ethylparaben that ethanol dissolves in the surface size, the consumption of ethylparaben is 0.8%-1.1% of starch dry weight.
The present invention can intercept bacterial invasion, and becomes the paper permeability good, the intensity height; Owing in the top sizing operation, use the ethylparaben of ethanol dissolving, have good cementability, resistance to water, pliability and colloid protectiveness, thereby make page have certain intensity and bursting strength.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
The present invention specifically may further comprise the steps:
(1) raw material is chipped;
(2) boiling;
(3) washing;
(4) screening purifies;
(5) washing concentrating;
(6) making beating;
(7) plasm-glue-blending liquid preparation section;
(8) surface size preparation section;
(9) slurry size degradation operation;
(10) top sizing operation, surface size uses cassava modified starch and polyvinyl alcohol;
(11) make finished product through hyperextension device stretching drying.
The present invention can intercept bacterial invasion, and becomes the paper permeability good, the intensity height.
During the size degradation operation, add hardwood pulp, softwood pulp when size degradation, hardwood pulp: the weight ratio of softwood pulp is 1: 4.5～5.5.
During the top sizing operation, contain the ethylparaben of ethanol dissolving in the surface size, the consumption of ethylparaben is 0.8%-1.1% of starch dry weight.
Owing in the top sizing operation, use the ethylparaben of ethanol dissolving, have good cementability, resistance to water, pliability and colloid protectiveness, thereby make page have certain intensity and bursting strength.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
