Description
Technical field:
What the present invention relates to is a kind of polymkeric substance silk ribbon, particularly be a kind of high-strength monoway stretched and oriented polymkeric substance silk ribbon of crosslinked with silicane.
Background technology:
Various films, silk ribbon (fibre-bearing, silk, arrowband) are extruded, are shaped to the crystalline polymer polymkeric substance through melt-processed, at it more than glassy state temperature, pick up the following suitable temp scope of fluidised form temperature, by unidirectional stretching, its goods are produced be higher than original not several times of the tensile strength of elongated article even ten times tensile strength, and make the heat, electricity, optics of other performances of its goods such as Young's modulus, elongation at break, resistance to impact shock, freedom from cracking performance, folding resistance and goods, performance such as ageing-resistant that further raising or improvement all be arranged.People utilize this processing characteristics of polymkeric substance to produce the silk of various unilateral stretchings, band (fibre-bearing, silk, arrowband), and then are processed into rope or are woven into fabric such as cloth, geo-grid, net.These goods have goodish intensity, the wireline that has replaced engineering and navigation to use in a large number; In road, dyke, expansion slope, roadbed, earthwork engineering, adopt in a large number, improved engineering life-span and quality.They are engineering materialss of extraordinary engineering material, particularly earthwork engineering.
But, because earthwork engineering all is a fundamental task crucial for generations to come, the ageing resistance of the rope that these unilateral stretching materials are made or the fabric of braiding generally the life-span in burying soil layer have only 20 years to 70 years, and along with the prolongation of time, enhancement in original engineering weakens year by year, final completely dissolve.In order to improve these aging resistance of materials as far as possible, the rope that these unilateral stretching materials are made, the fabric of braiding, people also address from different modes, make it to increase resistance of aging such as adding ultraviolet ray or absorb auxiliary agent in anti-material, perhaps adding in this material has the carbon black of shielding effect to increase resistance of aging to ultraviolet ray.But these measures still are the limited engineering life requirements that also do not reach to improving aging resistance and material engineering life-span.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, provide a kind of heat-resisting, heat-resistant aging, hydrolysis aging, environmental stress crack resistance, cracking, anti-gasoline and aromatic hydrocarbons, creep-resistant property improve greatly, the high-strength monoway stretched and oriented polymkeric substance silk ribbon of the crosslinked with silicane of long service life.
The object of the present invention is achieved like this:
The high-strength monoway stretched and oriented polymkeric substance silk ribbon of the present invention is to be formed through the hydrolytic condensation crosslinking reaction under wet heat condition through monoway stretch-oriented back by the silane-crosslinkable polymer silk ribbon again, the silane-crosslinkable polymer silk ribbon is to be formed by at least a polymkeric substance and organosilane monomer, grafting initiator, hydrolytic condensation catalyst preparation, and polymkeric substance is polyethylene, polypropylene or their multipolymer.
Above-mentioned silane-crosslinkable polymer silk ribbon is the flat film of silane-crosslinkable polymer or circular membrane branch to be cut to fillet form.
Above-mentioned polymkeric substance silk ribbon is to extrude cooling by rounded or special-shaped circle of silane-crosslinkable polymer or hollow shape bunchy, behind the stretch orientation, forms through the hydrolytic condensation crosslinking reaction again.
Above-mentioned polymkeric substance silk ribbon is to be silk ribbon to form again through hydrolysis-condensation reaction under wet heat condition through being punctured by porcupine roller or rotor before monoway stretch-oriented or in monoway stretch-oriented back by the flat film of silane-crosslinkable or circular membrane.
Above-mentioned polymkeric substance silk ribbon, is formed through the hydrolytic condensation crosslinking reaction under wet heat condition after extruding compound unilateral stretching by at least two layers of different silane-crosslinkable polymer material.
Above-mentioned polymkeric substance silk ribbon is three layers, comprise by the silane-crosslinkable polymer material through after monoway stretch-oriented, the crosslinked with silicane polymer layer that forms through the hydrolytic condensation crosslinking reaction under wet heat condition, the compound with it that is positioned at crosslinked with silicane polymer layer above and below can not crosslinked polymer layer.
Above-mentioned polymkeric substance silk ribbon be by at least two crosslinked with silicane polymkeric substance silk ribbons with twist or not twist close the strand form.
The cross-sectional shape of above-mentioned polymkeric substance silk ribbon is circle or flat-section or square or bending or circular arc or hollow shape.
Crosslinkable polymer is stretched earlier, and the macromolecular structure that the crosslinked art breading in back is arranged the two-dimensional directional behind the stretch orientation produces a part of tridimensional network, the high strength after making it that unilateral stretching be arranged, the crosslinked situation that has resistance of aging to increase again.People with this domain knowledge knows, it also is two-dirnentional structure that these above-mentioned materials all are linear structure, with regard to regard to a kind of polymer materials, through after the crosslinking reaction, this material transition is a tridimensional network, thermotolerance, heat-resistant aging, hydrolysis aging, environmental stress crack resistance, cracking, anti-gasoline and aromatic hydrocarbons, the creep resistance etc. of this material is had all raisings greatly of performance of material impact to aging resistance.Utilize crosslinked back material that the raising of good like this ageing resistance is arranged, come silane-crosslinkable unilateral stretching goods are carried out crosslinking reaction, produce high-tensile in the hope of obtaining after the unilateral stretching, on its two-dirnentional structure, produce tridimensional network after the crosslinking reaction and obtain the elongated article material of better ageing resistance such as the silk ribbon of unilateral stretching (fibre-bearing, silk, arrowband).Make the engineering life-span of these goods in earthwork engineering reach 50 to 100 years, surpass the engineering life-span of the material of existing art breading acquisition.We know that the silk ribbon in order to make above-mentioned unilateral stretching produces tridimensional network and obtains better ageing resistance at two-dirnentional structure, also there is employing that the drawn yarn band is carried out the high-energy electron width of cloth and penetrates crosslinked method, but the product cost height that this method obtains, unfavorable promoting the use of is not as the silane crosslinking process economically feasible.Do not have practicality.
