A kind of compound mildew-proof paper and preparation method thereof
Technical field
The present invention relates to a kind of compound mildew-resistant goods and preparation method thereof, especially relate to a kind of safety high efficient compound mildew-proof paper and preparation method thereof.
Background technology
At present, the blade after the tobacco leaf economy-combat leaf redrying of tobacco enterprise generally adopts carton or glued board packing.The conventional fungus-proof measure of storing smoked sheet mainly contains three kinds: the moisture content of (one) control storage smoked sheet is in less than 13% scope, and uniformity.Require to carry out two aspect work, 1. tobacco leaf warehouse-in and regular moisture content detect for this reason; 2. improve storage requirement: should there be good sealing, protection against the tide and ventilation, the facility that dries (adopting hygroscopic agent or dehumidifier to dry usually) in the tobacco barn storehouse.(2) in time the humiture in tobacco barn storehouse is controlled according to detection case; (3) strengthening tobacco leaf checks in the storehouse.Above conventional storage cigarette fungus-proof measure is mildew-resistant cost height not only, and anti-mold effect is undesirable.In recent years, tobacco enterprise uses the sheet cigarette generally to adopt packed in cases or wooden splint packing, uses the brown paper protection against the tide, takes formaldehyde to discharge measures such as mildew-resistant before the plank packing, and certain effect is arranged within a short period of time.Because smoked sheet reaches more than 1 year at storage alcoholization process time, plank, cardboard absorb the moisture content in the nature air, cause package panel cigarette moisture content to increase, and absorb airborne mould simultaneously.These factors are under the suitable situation of environment temperature, multiple moulds such as plank carton medial surface self-sow aspergillus candidus, these moulds have very strong repellence to the single mould inhibitor of general action, be difficult to eradicate, and can cause cross infection to go mouldy to smoked sheet, produce mould acid smell, cause negative effect, cause enormous economic loss to tobacco business to tobacco natural alcoholization.
Summary of the invention
At the above-mentioned shortcoming of prior art, it is easy and simple to handle that the present invention aims to provide a kind of use, in use non-stimulated, the compound mildew-proof paper of non-residual toxicity and manufacture method thereof.
The objective of the invention is to realize by the following technical solutions.
The present invention's anti-fungicide paper is basic paper with common brown paper or other similar paper or cardboard, applies or sprays composite type mouldproof agent, coated weight or sprinkling amount 〉=10g/m in the one side of basic paper
2(preferred version is 20-50g/m
2, I haven't seen you for ages excessively influences the effect and the timeliness of mildew-resistant; Too much can cause the waste of mould inhibitor, increase production cost), on described composite type mouldproof agent layer, be coated with the compound adhesive that one deck is added with mould inhibitor and antioxidant, coated weight 20-90g/m
2(preferred version is 40-70g/m
2).
The component of described composite type mouldproof agent and proportioning are: o-phenyl phenol 10~50 weight portions, benzoic acid 5~20 weight portions, propylben 2~20 weight portions, sorbic acid 10~30 weight portions;
The component of described compound adhesive and proportioning are: high speed cigarette adhesive or starch adhesive 20-70 weight portion, be selected from one or both mixture 5~15 weight portions in propionic acid, calcium propionate, the sodium propionate, carbendazim or benomyl 2~10 weight portions, vitamin E or C3~10 weight portions.
The manufacture method of anti-fungicide paper of the present invention may further comprise the steps: (1) selectes basic paper; (2) composite type mouldproof agent preparation, coating or sprinkling take by weighing o-phenyl phenol by preset blending ratio, benzoic acid, propylben, sorbic acid is dissolved in the ethanol of 2~3 times of weight under the greenhouse, treats to dissolve fully (to be accelerate dissolution, can suitably heat) after, apply or be sprayed on surface one side of basic paper, place the greenhouse oven dry again, promptly get semi-finished product; (3) contain mould inhibitor and antioxidant the preparation of compound adhesive, apply or spray take by weighing 1 by preset blending ratio) adhesive, 2) one or both in propionic acid, calcium propionate, the sodium propionate, 3) carbendazim or benomyl, 4) vitamin E or C mix, and stir, apply or be sprayed at (2) and go on foot the side that the semi-finished product that make have mould inhibitor, oven dry packs again, gets product.
The mould inhibitor raw material that the present invention uses is commercially available chemicals commonly used, as o-phenyl phenol, benzoic acid, propylben, sorbic acid etc., and wide material sources, and production technology is simple, and production process can not produce the three wastes.
The mould inhibitor that the present invention uses belongs to low toxicity compounds, and its toxicity is about about 3 times of salt, and is to the person poultry harmless, safe and reliable.
Product odorless of the present invention does not have specific peculiar smell, has eliminated fully to the stimulation of human organ and mucous membrane and to the contamination hazard that working environment causes, and does not influence the work situation that the workman operates in the warehouse.
Product of the present invention has the dual-use function that smoked, sterilization, anti-mildew fresh-keeping are steamed in contact.Antibacterial effect is not subjected to the influence of ambient temperature and humidity, and can make the chemical composition of tobacco leaf more become to coordinating, and can promote tobacco natural alcoholization,
Product of the present invention not only can be used for tobacco and goods mildew-resistant thereof, also can be used for mildew-resistant such as grain, feed.
The specific embodiment
The invention will be further described below in conjunction with embodiment, but they can not be interpreted as the restriction of scope that the present invention is asked for protection.
Embodiment 1
(1) chooses basic paper (brown paper); (2) take by weighing o-phenyl phenol 40kg, benzoic acid 20kg, propylben 15kg, sorbic acid 30kg, put into the reactor that has agitator, add 300kg ethanol, be heated to 60 ℃ and stir by the programming rate of 1 ℃ of per minute, after treating to dissolve fully, be sprayed on the one side of brown paper, advance the greenhouse oven dry, get semi-finished product, the mould inhibitor of having on the brown paper is 50g/m
2(3) take by weighing high speed cigarette adhesive 140kg, propionic acid 24kg, carbendazim 16kg, vitamin e1 0kg, mixing and stirring is coated in the side of semi-finished product with mould inhibitor again, and coated weight is 40-70g/m
2, place greenhouse oven dry again after, pack, be finished product.
The present embodiment compound mildew-proof paper the results are shown in following table to the bacteriostatic test of multiple mould:
