Abstract
The invention discloses a steel belt reinforced helical bellows and aims to provide a steel belt reinforced helical bellows which is high in adhesive property, high in tube quality and high in stability. The steel belt reinforced helical bellows comprises an inner polyethylene layer (8), an adhesive resin layer (2) and an outer polyethylene layer (1) which are sequentially arranged; a steel belt (3) is arranged in the adhesive resin layer (2), is a spiral steel belt, and is provided with holes (4); the adhesive resin layer (2) is crosslinked with the holes in the steel belt (3); a thickening layer (7) is arranged at each contact position of the inner polyethylene layer (8) and the steel belt (3).
Description
Technical field
The present invention relates to helical bellows technical field, provide a kind of steel band reinforced spiral ripple pipe.
Background technique
Steel band reinforced polyethylene spiral ripple pipe is applicable to various draining and the drainages such as municipal administration, industry, agricultural and traffic engineering construction.Which overcoming cement pipe is substantially all level and smooth straight shape pipe, and can not be incubated, as caliduct, steam line in use, owing to not being incubated, the problems such as heat loss, brings certain impact, and economic benefit is not high.Ring stiffness is high, easy to connect, low cost and other advantages owing to having for steel band reinforced polyethylene spiral ripple pipe, is used as the buried draining in the fields such as urban construction, blow-off line at present more and more.
At present, the mode of production of existing steel band reinforced polyethylene spiral ripple pipe is by expecting with steel band melting composite winding shaping at production line by PE.What mainly play rigidity effect is shaped-steel strip, and the thickness of shaped-steel strip and plastic inner pipe bond locations is outstanding does not reach certain ring stiffness.And its inner and outer wall adopts regenerated polythene and high density polyethylene (HDPE) (HDPE) to be raw material respectively, arranges steel band between inner and outer wall, need during making on steel band, to apply binding agent, so that steel band and inside and outside wall stick together.Because inside and outside wall raw material is variant, Material shrinkage rate is inconsistent, easily causes the problems such as deformation of products is large, a drum.Helical bellows integral adhesive is poor, anti-corrosion capability is weak, ring stiffness is not high, and existing plastics ribbon spiral bellows, when tube forming, keeps at a certain distance away between two adjacent rings steel band, namely between two adjacent rings steel band, plastic inner pipe exposes, reduce the bulk strength of tube wall, when being in use subject to the impact of sharp objects, easily cause tube wall to break and seepage, affect working life, limit its application area.
Summary of the invention
The object of the present invention is to provide a kind of adhesive property high, a kind of steel band reinforced spiral ripple pipe that the stability of high pipe workpiece quality is high.
The present invention is by the following technical solutions to achieve these goals:
A kind of steel band reinforced spiral ripple pipe, it comprises the interior polyethylene layer set gradually, adhering resin layer and outer polyethylene layers, steel band is provided with in adhering resin layer, steel band be helical steel band is arranged porose, hole on adhering resin layer and steel band is cross-linked, and the position that described interior polyethylene layer contacts with steel band is provided with thickening layer.
In technique scheme, steel band comprises U-shaped hat and limit pin, and limit pin is for evenly to reduce along U-shaped hat to edge thickness.
In technique scheme, on steel band, cloth hole density is 4 ~ 5/cm2, and the diameter in hole is 4 ~ 5 millimeters.
Because the present invention adopts above technological scheme, so possess following beneficial effect:
One, invention increases the thickness at steel band presser feet and interior polyethylene layer link position place, the ring stiffness that tubing is certain can be improved, improve the stability of pipe workpiece quality.Reduce the maintenance cost caused because of inwall cracking, and after thickness increase, greatly increase the working life of tubing.
Two, the present invention cloth hole on steel band, make interior adhering resin layer and steel band, crosslinked, one integrated mass, improves impact strength, the peeling strength of product, promotes productivity, avoids that inside and outside wall is rough, out-of-flatness.
