Description
Technical field
The invention belongs to handling and conveying band technical field, be specifically related to the preparation method of a kind of moldproof polyethylene light-type conveyer belt.
Background technology
Flourish along with logistic industry, logistics streamline equipment develops the most therewith, and this development proposes requirements at the higher level to the conveyer belt as streamline visual plant.PE light-type conveyer belt is typically with polyester textile as framework material, mainly for delivery of quality article light, middle.PE light-type conveyer belt is lightweight with it, life-span length, easy for installation, be not likely to produce the advantages such as friction, be widely used in the industries such as food processing, Nicotiana tabacum L..But at the processing environment that food or Nicotiana tabacum L. etc. are damp and hot, on conveyer belt, easy mould growth, pollutes product.Such as, the tobacco product hot and humid environment in the course of processing, it is easy to make PE light-type conveyer belt surface contamination mycete and can breed rapidly and extend, bringing harm to the health of tobacco product quality and people.
Therefore, meeting in the performance basis such as PE light-type conveyer belt physics and machinery, giving PE light-type conveyer belt mildew-resistant, drive mould function, there is very important practical value, the health level improving the people is had positive and important meaning.
Summary of the invention
It is an object of the invention to provide the preparation method of a moldproof polyethylene light-type conveyer belt, the fungistatic effect of mildew-resistant conveyer belt prepared by the method is notable, lasting, and nontoxic, complies fully with U.S. FDA food hygienic standard and EU REACH Legislation.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of preparation method of moldproof polyethylene light-type conveyer belt, its step includes:

(2), by fabric impregnated in the mildew-retarding liquid in step (1), pickup is 150-200g/m2, heat-shaping, form mildew-proof fabric；Preferably, described fabric is PET polyester textile.
(3), use the method for calendering to be combined with mildew-proof fabric by PE, form conveyer belt composite bed；In recombination process, rolling temperature is 130-150 DEG C, and composite pressure is 10-15Pa, and the cloth surface temperature of mildew-proof fabric is maintained at 120-150 DEG C；
(4), the PE surface of the conveyer belt composite bed in step (3) is carried out sided corona treatment；
(5), by antifungus agent it is added in water polyurethane surface treating agent formation mildew-resistant surface treatment liquid, then mildew-resistant surface treatment liquid is coated in step (4) the PE surface of the conveyer belt composite bed after sided corona treatment, dries.
In described step (2), it is 0.5-1 minute that fabric impregnated in the dip time of mildew-retarding liquid；The condition of described heat-shaping is Far-infrared Heating, and heating-up temperature is 80-90 DEG C.Fabric be impregnated in mildew-retarding liquid so that be filled with mildew-retarding liquid between the surface of fabric and the gap of fabric, add the anti-mold effect of final products.
In described step (3), the thickness of the PE layer in described conveyer belt composite bed is 0.05-0.1cm, and the thickness of mildew-proof fabric is 0.05cm.Suitably textile matte structure and thickness, determines conveyer belt and has and the most flexible the most also have higher intensity, can meet the needs of various use environment.
In described step (4), during sided corona treatment, the corona time is 0.5-1 minute, corona discharge power 1-3KW；Preferably, during sided corona treatment, the corona time is 0.5 minute, corona discharge power 1.95KW.PE surface is processed, the attachment of follow-up mildew-resistant surface treatment liquid, preferred corona condition, determine the existing a number of active group in PE surface, it is easy to follow-up mildew-resistant process, the structure of PE will not be caused excessive injury again, affect its serviceability.
In described step (5), the antifungus agent content in mildew-resistant surface treatment liquid is 0.5-2%；Mildew-resistant surface treatment liquid coated weight is 20-40g/m2.Preferably, the antifungus agent content in mildew-resistant surface treatment liquid is 1%；Mildew-resistant surface treatment liquid coated weight is 30g/m2.Coating by mildew-resistant surface treatment liquid so that antifungus agent can concentrate on PE surface, and suitably coated weight, determine itself and the PE compatibility, thus have impact on mildew-resistant endurance.Coated weight is too much, easily causes unnecessary waste, adds production cost, and coated weight is very few, does not reaches anti-mold effect.
Preferably, described antifungus agent is N-(2-2 chlorovinyl) salicylamide.
The invention has the beneficial effects as follows:
1, the moldproof polyethylene light-type conveyer belt prepared by the present invention can kill mycete, and suppresses mycete to regenerate, harmless, and has the highest chemical stability and heat stability.
2, the antifungus agent on the moldproof polyethylene light-type conveyer belt surface in the present invention is good with the PE compatibility, processing characteristics and other mechanical property on conveyer belt are without impact, antifungus agent concentrates on PE surface, there is the most potent anti-mold effect, and the fabric of conveyer belt also impregnated in mildew-retarding liquid, significantly increased anti-mold effect.
3, the present invention provides moldproof polyethylene light-type conveyer belt to comply fully with U.S. FDA food hygienic standard and EU REACH Legislation, is a kind of long-lived conveying products, can be used for the conveying in the field such as food, medicine.
