Description
Technical field
The invention belongs to non-woven composite and preparation field, more especially relate to a kind of Chinese medicine slag filling non woven composite material and preparation method thereof.
Background technology
Recent years, along with countries in the world to the concern of the traditional Chinese medical science and to the unique curative effect of traditional Chinese medicine affirm that the development of Chinese medicine new varieties is climax day by day, day by day favor herbal species in modernized pharmaceutical factory with considerable scale, the Chinese medicine planting scale sharply increases.But Chinese medicine can produce a large amount of discarded object-Chinese medicine slags adding man-hour, and how handling these dregs of a decoction is that manufacturer and social enviroment protection are all felt very stubborn problem.The research report that at present relevant Chinese medicine slag rationally utilizes is very few, and belongs to pilot study more, and this has caused the waste of resource to a certain extent.At present Chinese medicine slag is taked following processing mode basically:
(1) stacking, landfill, burning
Chinese medicine slag generally transports plant area by production unit, takes stacking, landfill, burning disposal, wherein stacks to be principal mode.But because of reasons such as rain-outs, easily cause the pollution of stacking place surrounding environment, especially even more serious to the influence of water quality.
(2) adopt fermentation heap extensive use of chemical fertilizer technology, make organic fertilizer or feed
With microbiological treatment or use the poultry manure mixed processing, making it is the approach that effectively utilizes Chinese medicine slag as agricultural green manure with Chinese medicine slag.Or utilize biotechnology that Chinese medicine slag is converted into animal feeding-stuff containing somatic protein, and be used for animal husbandry, home poultry raising industry, both variable the expense, cost-saved again for precious.
For landfill, composted can turn waste into wealth, and meets the development trend of cleaner production, but because the crude fiber content height of Chinese medicine slag, effectively nutritional labeling is limited, and this technology is not also promoted on a large scale.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of Chinese medicine slag filling non woven composite material and preparation method thereof, and technology of the present invention is simple, turns waste into wealth, and can bring into play the antibacterial action of Chinese medicine slag.
One of technical scheme of the present invention provides a kind of Chinese medicine slag filling non woven composite material, and it is to be made of non-woven base fabric material, packing material Chinese medicine slag, thermal fusing powder, four kinds of components of curing agent.
Described packing material Chinese medicine slag, the root, stem, the leaf that mainly are plant pass through the medicinal material residue of decocting and concentrating, contain abundant bast fiber, be that medical processing enterprise produces the main solid waste that produces in the Chinese herbal medicine process, in order to improve the distributing homogeneity of Chinese medicine slag in nonwoven material, it is ground into earlier Powderedly is applied again.
Described non-woven composite structure is to add two-layer packing material or the sandwich that the rest may be inferred in the sandwich that adds packing material in the two-layer base cloth, the three layers of base cloth.
Described thermal fusing powder is the lower high molecular polymer of fusing point, for example ethylene-vinyl alcohol copolymer.
Described curing agent is heat cured high-molecular resin solution, for example epoxy resin solution.
Two of technical scheme of the present invention provides a kind of preparation method of Chinese medicine slag filling non woven composite material, may further comprise the steps:
(1) lapping
After the 3%-80% Chinese medicine slag made powder, be spread on equably on the non-woven base fabric material, make the non-woven composite of said structure together with the 2%-40% thermal fusing powder;
(2) preform
The sandwich that step (1) is made is put into pre-compaction forming on the vulcanizing press of heating, and adhesive effect is played in the thermal fusing powder fusing, makes three kinds of bonding reinforcings of component.Heating-up temperature is determined pressure 1-12Mpa, time 1-5min (being decided by base cloth grammes per square metre and thermal fusing powder addition) according to the fusing point of thermal fusing powder.
(3) solidified forming
With the curing agent (as epoxy resin solution) of the material soaking 10%-80% of step (2), the material of acquisition is put into the vulcanizing press heating and pressurizing under uniform temperature and pressure condition, can obtain the Chinese medicine slag filling non woven composite material.Solidification temperature, pressure and time are decided by the kind and the consumption of curing agent.
Beneficial effect
Production technology of the present invention is simple, and flow process is short, the production efficiency height; Cost is low, particularly adds Chinese medicine slag, has solved it and has handled a difficult problem, turns waste into wealth; Low to the base material selectivity, spunbond, the hot rolling non-woven base fabric of fibrous materials such as traditional nonwoven material base cloth such as polyester, polyethylene, polypropylene all can; The material that obtains is satisfying outside the performances such as vibration isolation, heat resistance, sound insulation, sound absorption properties, thermal insulation, resiliency, because the interpolation of Chinese medicine slag also gives material certain antibacterial action, adapt to the situation of creating conservation-minded society, satisfied the requirement of people the life health security.
