Embodiment 1

[0040] Figure 1 to Figure 9 Figure 1 of Embodiment 1 of the present invention is given. see figure 1 , Polyethylene material and silane cross-linkable polymer ribbons containing organosilicon monomers, grafting initiators, and hydrolytic condensation catalysts are prepared by unidirectional stretching and orientation, and then hydrolyzed, condensed, and cross-linked under humid heat conditions. The cross-sectional shape of the silane-crosslinked high-strength uniaxially stretched oriented polymer ribbon 1 is as follows figure 2 shown as a rectangle or as image 3 Shown as a diamond or as Figure 4 Shown as round or Figure 5 shown as hollow circular or as Figure 6 Shown as oval or as Figure 7 shown as a triangle or as Figure 8 Groove shape as shown or as Figure 9 The convex shape shown.

Embodiment 2

[0042] The two-layer material is polyethylene or polypropylene material, which is composed of silane cross-linked polyethylene layer 2 and silane cross-linked polypropylene layer 3 after extrusion composite uniaxial stretching, and undergoes hydrolysis condensation cross-linking reaction under humid heat conditions. Silane-crosslinked high-strength polymer ribbons. Its cross-sectional shape is as Figure 11 shown as a rectangle or as Figure 12 Shown as a diamond or as Figure 13 Shown as round or as Figure 14 shown as hollow circular or as Figure 15 Oval as shown or as Figure 16 shown as a triangle or as Figure 17 Grooved as shown or as Figure 18 Convex shown.

Embodiment 3

[0044] Figure 19 shows a diagram of Embodiment 3 of the present invention. Referring to FIG. 19 , non-crosslinkable polymer layers 5 and 6 are compositely connected to the top and bottom of the silane crosslinked polymer layer 4 , respectively.

Abstract

The present invention is polymer band of silane-crosslinked polymer through monoway stretching and orientation and subsequent hydrolysis, polycondensation and crosslinking in wet and hot condition. It has greatly raised heat resistance, heat aging resistance, hydrolysis aging resistance, environment stress resistance, crack resistance, gasoline and arene resistance, and creepage resistance and long service life.

Description

Technical field: [0001] The invention relates to a polymer ribbon, in particular to a silane-crosslinked high-strength uniaxially stretched and oriented polymer ribbon. Background technique: [0002] Crystalline polymers are extruded and formed into various films and ribbons (including fibers, filaments, and narrow ribbons) through melt processing, and are uniaxially stretched at a suitable temperature range above the glass transition temperature and below the twisting state temperature. , can make its products several times or even ten times higher than the tensile strength of the original unstretched product, and make other properties of the product such as elastic modulus, elongation at break, impact strength, Crack performance, folding resistance, and thermal, electrical, optical, aging resistance and other properties of the product have been further improved or improved. People use the processing characteristics of polymers to prepare various unidirectional stretched f...
