Abstract
The invention provides a polypropylene-rubber composite corrugated pipe. The manufacturing steps of the polypropylene-rubber composite corrugated pipe are as follows: (1) a preformed polypropylene corrugated pipe product is made, specifically, dried and preheated polypropylene resin is delivered into an extrusion machine to be subjected to plastifying extrusion, compression molding and cooling setting, then fixed-length cutting is carried out, and the preformed polypropylene corrugated pipe product is obtained; (2) post-processing of the polypropylene corrugated pipe is carried out, specifically, the preformed polypropylene corrugated pipe product obtained in the step (1) is subjected to installation sizing, sintering, quenching in water, flanging, finishing and gluing sequentially, so that the polypropylene corrugated pipe subjected to post-processing is obtained; and (3) the polypropylene corrugated pipe is compounded with rubber so that the polypropylene-rubber composite corrugated pipe can be obtained. The polypropylene-rubber composite corrugated pipe retains the excellent physical and chemical properties of polypropylene, and due to presence of the rubber component, the defect of poor toughness is overcome, impact resistance is greatly improved, and physical properties of the product are improved.
Description
Technical field
The present invention relates to a kind of polypropylene/rubber combined corrugated tube, belong to Bellows Technology field.
Background technology
Corrugated tube refers to the tubular elastomeric sensing element being connected into foldable wrinkle piece along folding retractable direction.Corrugated tube
Instrument and meter is widely used, is mainly used for the measuring cell as pressure measuring instruments, convert pressure into displacement or
Power.Ripple tube wall is relatively thin, and sensitivity is higher, and measurement range is tens of handkerchiefs to tens of MPas.Its opening is fixed, sealed end
It is in free state, and the helical spring using auxiliary or reed increase elasticity.During work internally in the presence of pressure along pipe
Sub- elongated lengthwise, makes movable end generation become the displacement of certain relation with pressure.Movable end drives pointer can directly indicate
The size of pressure.Corrugated tube is usually combined with displacement transducer and constitutes the pressure transducer being output as electricity, sometimes also uses
Make isolation element.
Content of the invention
The purpose of the present invention be overcome the deficiencies in the prior art in place of, a kind of polypropylene/rubber combined corrugated tube is provided.
The polypropylene of the present invention/rubber combined corrugated tube, makes as follows：
1）Prepare polypropylene corrugated tube pre-shaped articles：Acrylic resin after drying and preheating is delivered in extruder, carries out
Plasticizing extrusion, compression molding, after cooling and shaping, carry out fixed length cutting, obtain polypropylene corrugated tube pre-shaped articles；
2）Processed after polypropylene corrugated tube：By step 1）The polypropylene corrugated tube pre-shaped articles obtaining are installed successively
Shaping tire, sintering, quenching-in water, flange, finishing, gluing are processed, and obtain the polypropylene corrugated tube of rear processed；
3）Prepare polypropylene/rubber combined corrugated tube with rubber combined：By step 2）The polypropylene ripple of the rear processed obtaining
Stricture of vagina pipe and rubber combined sulfuration, carry out the demoulding, deburring Final finishing successively, obtain polypropylene/rubber combined corrugated tube.
The polypropylene of the present invention and rubber composite product remain the excellent physical and chemical performance of polypropylene, due to rubber
The presence of composition, overcomes the not enough defect of its toughness, and impact resistance greatly improves, and the physical property of product is improved.
