Abstract
The invention discloses a novel mildew-resistant drying agent for overcoming the problem that prior art drying agents in leather and leather products can only be passively bacteriostatic or can only reduce the humidity to reduce the chance of mildewing. The novel mildew-resistant drying agent can take the initiative to kill the mould in the environment of the leather and leather products and effectively remove harmful substances of formaldehyde, benzene and the like in the leather and leather products. The raw materials including granular sodium chlorite, tartaric acid and sodium chloride are respectively crushed in a crusher; PEG6000 is added; the granular sodium chlorite, the tartaric acid, the sodium chloride and the PEG6000 are mixed uniformly in a mixer in a ratio of 0.2: 0.4: 0.3: 0.1 by weight; and tablets having a weight of 1-2 g are obtained through tabletting in 30% RH humidity. Kaolin ore and calcium chloride are crushed in the crusher; the kaolin ore and the calcium chloride are mixed uniformly in the mixer in a ratio of 4: 1 by weight; and a mixture of the kaolin ore and the calcium chloride is prepared into granules with a particle size of 3-5mm in a comminutor. The tablets and the granules are filled in waterproof ventilated membrane bags with the openings sealed through use of a packing machine. When in use, two bags of the drying agent are put in a shoe box of a pair of men shoes and the validity period of use can be six months.
Description
Technical field
The present invention relates to leather and leather and fur products mildew-resistant and purification, especially the passive mildew-resistant of existing leather is become and initiatively kill mould and can remove harmful components such as formaldehyde in leather and the leather and fur products, benzene.
Background technology
Leather and goods go mouldy and the event that exceeds standard of harmful substance is sustained a great loss country and business economic, prevent that the method that leather and goods go mouldy is a lot, but also do not have a kind of simple, easy capable, effective, cheap and safe method so far.The mould inhibitor product category that is used for leather and goods mildew-resistant is various, and the mould inhibitor that most of tanneries use also is effective.But, general all can bring in various degree influence or harm to the mankind, animal, environment etc., and most valuable product, the use cost height.In recent years, along with the continuous enhancing of people's environmental protection and health perception, various countries are to being used for the increasingly stringent that requires of leather chemical industry material.Commonly used mould inhibitor such as penta sodium pentachlorophenate, ethyl naphthol, p-nitrophenol etc. on the leather in the past because toxicity is too big, progressively is eliminated or bans use of.And along with the increasingly stringent of environmental regulation, many present also widely used leather fungicides may be limited to use.
" a kind of mildew-resistant clarificant and production method that can be used for leather and leather and fur products " based on medical science sterilization and the development of depollution of environment principle fundamentally changed the method for preventing and treating that traditional leather industry goes mouldy, the passive antibacterial sterilization that becomes active.Simultaneously, can also effectively dispose in the process of storing and transport the harmful substance in leather and the goods.In addition, this invention also has following premium properties:
(1) mould in leather and the goods is had the bactericidal properties of wide spectrum, bactericidal action is strong and mould do not had pesticide resistance;
(2) can effectively remove harmful substance and peculiar smell in leather and the goods;
(3) safe, nontoxic, non-stimulated, not carcinogenic to human body, can not produce effects such as allergy;
(4) easy to use, can not reduce result of use because of the influence of acid, alkali or other composition;
(5) dispersiveness is good, does not influence key property and the color of product;
(6) Environmental compatibility is good, can not pollute easily biological-degradable;
(7) cheap.
The present invention is highly significant to the mildew-resistant of leather industry, harmful substance and the environmental protection in the removal leather.
Summary of the invention
In order to overcome the antibacterial mouldy problem of humidity minimizing that maybe can only reduce that existing desiccant can only be passive in leather and leather and fur products, the invention provides a kind of novel mildew resistant desiccant, can initiatively the mould in leather and the leather and fur products environment be killed and effectively be removed harmful substances such as formaldehyde in leather and the leather and fur products, benzene.
A kind of mildew-resistant clarificant and production method that can be used for leather and leather and fur products comprises the steps:
(1) at first, feed particles shape sodium chlorite, tartaric acid, sodium chloride are crushed to the 100-120 order respectively in cracker, the letter sorting back of sieving is stand-by;
(2) will sieve that to be dried to moisture with 120 ℃ temperature respectively in dryer stand-by below 0.5% for the stand-by powdery sodium chlorite in letter sorting back, tartaric acid, sodium chloride;
(3) dried powdery sodium chlorite, tartaric acid, sodium chloride are added PEG6000 again, by 0.2: 0.4: 0.3: 0.1 part by weight carried out compressing tablet after fully mixing under the humidity of 30%RH in agitator, make the tablet of 1-2g;
(4) kaolin ore and calcium chloride powder are broken to the 120-150 order, after fully mixing in agitator by 4: 1 part by weight, granulation in comminutor, particle diameter is 3-5mm;
(5) the kaolin ore that will make and calcium chloride particle are dried to moisture with 120 ℃ temperature in dryer stand-by below 1%;
(6) with packing machine with tablet and particle by 1: the part by weight can of 3-5 is in the waterproof ventilated membrane bag and seal.
Embodiment
(1) at first, feed particles shape sodium chlorite 22kg, tartaric acid 44kg, sodium chloride 33kg are crushed to the 100-120 order respectively in cracker, it is stand-by to cross 100 mesh sieves letter sorting back;
(2) will the sieve stand-by powdery sodium chlorite in letter sorting back, tartaric acid, sodium chloride carried out drying 3 hours with 120 ℃ temperature respectively in dryer, and be stand-by below 0.5% to moisture;
(3) dried powdery sodium chlorite 20kg, tartaric acid 40kg, sodium chloride 30kg are added people PEG6000 10kg again, in agitator, behind the abundant mixing 10min, under the humidity of 30%RH, carry out compressing tablet, make the tablet of 1g;
(4) kaolin ore 250kg and calcium chloride 70kg are crushed to 120 orders, in agitator, fully mix 20min after, granulation in comminutor, particle diameter is 3-5mm;
