Abstract
The utility module disclose a PET (Polyethylene terephthalate) compound belt which comprises a sandwich layer, two adhesive layers and two PET membranous layers, wherein the sandwich layer is made by adopting PET fibers; the two adhesive layers are respectively arranged on two sides of the sandwich layer, comprise adhesives and are used for connecting the sandwich layer and PET membranous layer; the two PET membrane layers are respectively arranged on the other surfaces of the two adhesive layers and are made by adopting PET membranes. In the PET compound belt, the PET fiber is used for replacing glass fiber; and the manufactured PET compound belt is high in tensile strength and strong in stretching force.
Description
Technical field
The utility model discloses a kind of PET band, is a kind of compound band that is wrapped of PET that is used on the cable-stayed bridge suspension bridge cable wire alive more specifically.
Background technology
Because suspension cable generally places the beam external body, is subjected to the corrosion of atmospheric environment, works under heavily stressed load for a long time throughout the year, its sectional dimension is again little, and is very responsive to corrosiveness.Even slight corrosion takes place suspension cable, its anticorrosive intensity also has than macrolesion.Therefore service life of cable-stayed bridge, depend on the resistance to corrosion of suspension cable self to a great extent.
For hot extruded polyethylene half parallel steel wire zip,, steel tendon need be carried out slightly entad left-hand twisting for the ease of transportation.Be the shape of hawser after the maintenance twisting, band is wrapped hawser with being wrapped.Thereby the band reply cable wire that is wrapped do not have corrosiveness, and its pH value also needs enough tension intensitys and toughness simultaneously in 6.5～8.5 scopes.
Existing compound PET band, by two-layer PET film therebetween glass fibre strengthening tensile strength, but glass fibre fragility is big, not folding, and together after the friction, the loss of tensile strength is big.
Summary of the invention
At above-mentioned defective, the utility model purpose provides a kind of tensile strength height, the PET composite band that stretching force is strong.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of PET composite band of the present utility model comprises one deck sandwich layer, and is fibrous by PET;
Two-layer adhesive layer lays respectively at the two sides of sandwich layer, is made up of adhesive, is used to connect sandwich layer and PET rete;
Two-layer PET rete lays respectively at the another side of two-layer adhesive layer, is made up of the PET film.
In a kind of preferred embodiment of the present utility model, described sandwich layer is surrounded the four sides by PET rete and adhesive layer.
In a kind of preferred embodiment of the present utility model, described adhesive is the high-strength glue of acrylic acid.
In a kind of preferred embodiment of the present utility model, described PET film thickness is 0.02-0.35mm.
In a kind of preferred embodiment of the present utility model, described core layer thickness 0.02-0.8mm.
A kind of PET composite band of the present utility model replaces original glass fibre with the PET fiber, made PET composite band tensile strength height, and stretching force is strong.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1.
Wherein 1 is the PET film, and 2 is the PET fibrage; 3 is glue layer.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
In conjunction with shown in Figure 3, PET composite band of the present utility model comprises the fibrous sandwich layer of PET as Fig. 1, and described sandwich layer both sides are the adhesive layer that adhesive forms, and the another side of adhesive layer is the PET film, described adhesive layer be used for boning sandwich layer and PET film.Described adhesive can be viscous adhesive water, and the sticky agent in the present embodiment is the high-strength glue of acrylic acid.
As Fig. 1 in conjunction with shown in Figure 2, the fibrous sandwich layer of described PET a centre in the PET composite band, the both sides of PET composite band are directly combined by sticky agent by two-layer PET film, the PET fibrage just is enclosed in the centre by adhesive layer and PET film like this, and each layer of described PET composite band is very firm with regard to combination.Particularly to the tension requirement of strength when high, the PET fibrage can be thicker, and adhesive not infiltration evenly do not have bonding very firm situation between the described PET fiber, it is loose just each layer can not occur in this way, thus the situation that influence is used.
