The present invention produces useful material with waste and has low production cost.
Description
Technical field
The present invention relates to waste tank furnace filament reutilization technology field, particularly relate to the method for utilizing waste tank furnace filament to prepare short glass fiber.
Background technology
In general, the glass fiber industry production technique has two kinds of the wire drawing of platinum stove and pool kiln wiredrawings.Wherein platinum stove drawing process is more backward, uses fewer and feweri; And the tank furnace drawing process application surface is more and more wider.These two kinds of technologies all can produce a large amount of glass fibre waste silks.These waste silks mainly are made up of the crin that hard silk that produces before the higher authorities and mandrel end cap produce.The composition of all waste silks is the same with the composition of glass fibre finished product, belongs to the silicate material in the ceramic, is the nondegradable solid pollutant of nature.Domestic glass fibre manufacturing enterprise mostly adopts buried mode to handle waste silk, the processing costs height, and produce follow-up pollution hidden trouble.
It is the method for raw material production glass fibre with the glass fibre waste silk that Chinese invention patent application 02142489.1 discloses a kind of, feature is to comprise the steps: the flushing of (1) glass fibre waste silk water, remove its surperficial organism, with pulverizer the glass fibre waste silk is pulverized subsequently, and removing refractory materials, metal and other impurity, with the dehydration of glass fibre waste silk, water ratio is below 12% then; (2) waste silk that step (1) is handled drops into the tank furnace fusing, and temperature is 1400～1600 degree, and finished product is made in wire drawing subsequently.Though this method can utilize the tank furnace waste silk to produce glass fibre, but will be through melting and wire drawing again, and processing costs is very high, and produces new waste silk.
China side patent application 02812959.8 discloses and has a kind ofly prepared the method for ceramic product by fiber glass waste, comprises the steps: fiber glass waste is reduced to glass powder; Glass powder is mixed a kind of glass-additive agent mixture of formation with additive; Granulated processed makes it to become granular particles; Be shaped to ceramic product goods green compact, be heated into ceramic product.Wherein additive mainly is a filler, is used to improve the ceramic product performance.This method also needs high temperature sintering, the processing costs height.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of method of utilizing waste tank furnace filament directly to prepare short glass fiber cheaply is provided.
Purpose of the present invention is achieved through the following technical solutions:
Utilize waste tank furnace filament to prepare the method for short glass fiber, comprise the steps:
(1) waste tank furnace filament bulk processing: remove waste tank furnace filament impurity, add entry or dry, the water ratio that makes waste tank furnace filament is 2～5%;
(2) configuration of binding agent: the binding agent of water-soluble or water and milk is diluted with water to the situation that can spray, and described binding agent is selected from one or more in Resins, epoxy, vibrin, polyvinyl acetate (PVA) and the urethane;
(3) spraying of binding agent: binding agent is sprayed on the waste tank furnace filament or waste tank furnace filament is immersed in the binding agent after the dilution, leave standstill, binding agent is fully absorbed, the weight ratio of binding agent and glass fibre is 1: 5～20;
(4) the short glass fiber forming process is handled: will shear, screen through the waste tank furnace filament that has binding agent that step (3) is handled, baking filters out short glass fiber at last then.
The removal waste tank furnace filament impurity of described step (1) is to remove impurity such as the plaster on waste tank furnace filament surface and paper scrap.
Described step (2) binding agent is diluted with water to and can the spraying situation be meant that the weight percent concentration of binding agent is 15～25%.
The time of repose of described step (3) is 8～24 hours, and binding agent is fully absorbed.
Screening after described step (4) waste silk is sheared is meant by vibratory screening, selects qualified model.
The baking of described step (4) is at 90～120 degree, storing time 14～20 hours.
Short glass fiber of the present invention is meant that length is the glass fibre of 3-10MM.
With respect to prior art, the present invention has following advantage:
(1) has cost advantage preferably.The market price of the fine cost of short glass fiber is; 9000-12000 unit/T, owing to need not high temperature sintering, the cost of the short glass fiber by method preparation of the present invention is 4000 yuan/T, has stronger cost advantage.
(2) intensity of increase short glass fiber.Fiber increases with combining greatly of resin after the spraying adhesive, disperses better to improve 10% than the intensity that does not have adding additives.
(3) blanking is convenient.Because not having the glass of adding additives is the shape thing that looses, substantially cannot normal blanking, the glass of adding additives is a block, blanking is smooth and easy.
(4) wearing and tearing greatly reduce to forcing machine.Because it is long that short glass fiber has been cut into 3-10MM, reduces shearing force greatly.Can reduce in the extrusion process the wearing and tearing of forcing machine, compare with long glass fibres, wearing and tearing then greatly reduce to forcing machine for it.
(5) turn waste into wealth, the feature of environmental protection is good.Method waste tank furnace filament utilization ratio height of the present invention does not need the buried processing of large-scale waste material, has eliminated the hidden danger that buried processing forms, and utilizes the big short glass fiber of demand on the waste material production market simultaneously, and really having accomplished turns waste into wealth.
