Description
Technical field
The invention belongs to tire manufacturing techniques field, relate to a kind of method based on high energy electron process dipped cord measuring fiber or cord.
Background technology
The production of current cord fabric mainly comprises precursor, twisted weave, the large production process of impregnation three; Wherein gum dipping process comprises again the large operation of impregnation, drying and shaping three.
With regard to drying process, the main hot-air seasoning technology that adopts carrys out dry dipped type cord fabric at present, method be specially cement dipping machine to after cord fabric impregnation by roller group, drying oven is arrived again after unnecessary glue is extruded pressing, by hot air circulation mode, hot blast is made vertically to spray to cord fabric from discharge in stove in low flow rate strand mode, cord fabric passes through 4 strokes (baker is high 30 meters) in stove, adopt many warm areas control temperature (about 160 degree), what hot gas and cord fabric were evaporated mixes containing glue moisture, except sub-fraction discharges stove, the overwhelming majority is recycled blower fan and draws back and the gas and vapor permeation newly burnt, blast again in stove and complete the oven dry of the cord fabric after to impregnation, and then deliver to shaping furnace, adopt hot blast to continue cord fabric heating, cord fabric is adjusted shape under high temperature and tension force effect, the length of whole production line is at more than 40 meters, the speed of cord fabric is at 12 ~ 85 ms/min.
Hot-air seasoning technical disadvantages is more, is mainly reflected in the several aspect of the energy, environmental protection, work efficiency and equipment, specific as follows:
1, energy consumption is high: whole technique needs to consume mass energy to provide hot blast;
2, pollute greatly: the impregnated resin solid content used owing to matching with hot-air seasoning technology is low, heating causes a large amount of volatilizable solvent evaporates, causes VOC to discharge, serious environment pollution;
3, efficiency is low: the dry run time is long, causes overall efficiency low;
4, equipment is large: equipment not only floor space greatly, highly high, and complex structure, difficult in maintenance.
High-power electron beam dry technology, because its cost is low, curing rate is fast, and VOC free discharges, and excellent performance after dry solidification, has energy-saving and environmental protection, the advantage such as efficient, is widely used in curing varnish, ink, coating etc. abroad.
But because high energy electron generation equipment and cord fabric professional span are very large, the equipment that do not produced by high energy electron temporarily both at home and abroad is at present applied directly to the precedent in the production technology of making cord fabric; And domestic high energy electron generation equipment is rare, and application technical research history is shorter, and does not have corresponding experimental facilities, so adopt the dry dipped type cord fabric research of high energy electron also in the innovation starting stage.
Summary of the invention
The object of this invention is to provide the method for the simple dry dipped cord measuring fiber of a kind of technique or cord, by high energy electron, drying is carried out to dipped cord measuring fiber or cord.
In order to achieve the above object, the invention provides the method based on high energy electron process dipped cord measuring fiber or cord, the cord fibers or cord that are soaked with hardening with radiation impregnated resin are solidified through high-energy electron irradiation, wherein radiation absorber amount is 0.5 ~ 60KGy.
According to the cord fibers after process or cord, the cord fabric finished product directly made, without the need to carrying out the operation such as impregnation, oven dry again.
High energy electron dry solidification principle: be by high energy electron and glue interaction of molecules, makes it to resolve into free radical and causes macromolecule homopolymers and reactive diluent and be cross-linked.
Preferably, described radiation absorber amount is 0.5 ~ 20KGy.
Preferably, described high-energy electron irradiation condition is voltage 200 ~ 600KV.
Preferably, through electron irradiation solidification under the limit oxygen environmental protection that described cord fibers or cord manufacture at protective gas, described protective gas is selected from the composition of one or more in nitrogen, carbon dioxide, inert gas.Easily there is oxygen inhibition in the fiber after impregnation or cord, so-called oxygen inhibition under high-energy electron irradiation, and referring to oxygen can compete with the polymerisation of free radical and consume free radical.Prevent the generation of oxygen inhibition, in the middle of prior art, describe multiple feasible method.The present invention prevents oxygen inhibition from occurring by reaching with protective gas manufacture limit oxygen environment.Wherein compare between nitrogen, carbon dioxide, inert gas, from technique, cost and drying effect, select carbon dioxide more better as protective gas.
Preferably, in whole irradiation process, described cord fibers or cord are transmitted by transfer system, and described transfer system comprises conveyer belt or transmission roller.By transfer system, cord fibers or cord are transmitted, reach and ensure that whole irradiation process links up and stable object.
Preferably, described hardening with radiation impregnated resin is with parts by weight, be made up of the polyisocyanates of 100 ~ 300 parts, the acrylate of 70 ~ 240 parts and the alkene ether type monomer of 10 ~ 40 parts, described polyisocyanates is selected from the composition of one or more in the isocyanates containing two or more isocyanate group.
Compared with prior art, beneficial effect of the present invention is:
Without the need to consuming mass energy, reach the object of energy-saving and emission-reduction; Hardening with radiation process is consuming time very short simultaneously, greatly improves production efficiency; And the production equipment related to hotter drying plant volume is little and structure simple, cost more easy to control and maintenance.
