Abstract

The utility model discloses a novel steel-plastic composite glass reinforced plastic sleeve, consisting of an outer layer and an inner layer, wherein the inner layer is a tubular modified polypropylene layer, and the outer layer is a glass reinforced plastic composite material outer layer. The novel steel-plastic composite glass reinforced plastic sleeve is characterized in that the glass reinforced plastic composite material outer layer is adhered to the outer wall of the tubular modified polypropylene layer through adhesive. The novel steel-plastic composite glass reinforced plastic sleeve has the following advantages: 1, the strength is high; 2, the toughness is good; 3, the fire resistance is good; 4, the inner layer adopts the modified polypropylene material with small friction coefficient, compared with the conventional glass reinforced plastic, the friction coefficient is greatly reduced, the inner wall of the inner layer is level and smooth, low in resistance and is easy for a cable to pass through, and the cable passing efficiency is high; and 5, the shock and damage resistance is good, the outer layer is high in rigidity, the inner layer is good in flexibility, and the rigidity and flexibly are reasonably combined. By adopting the dual-layer structure, the inner layer still can guarantee the use performance of the tubular material when the outer layer is damaged.

Description

Novel steel/plastic compound glass steel sleeve

Technical field

The utility model relates to a kind of industrial tubing, relates in particular to a kind of Novel steel/plastic compound glass steel sleeve.

Background technology

The tubing in the fields such as power cable, communication sheath, draining blowdown much is the traditional glass steel tubing at present, and there is following shortcoming in the traditional glass steel tubing: 1, inner wall coarse, and it is large to wear the cable resistance; 2, be prone to the sand fallout phenomenon, cause cable can't pass through or damage cable; 3, single layer structure, anti-destructive is poor; 4, poor fire, catching fire can spontaneous combustion (standard No.: DL/T802.2).

Common MPP(modified polypropene) there is following shortcoming in tubing: 1, hot strength is lower, for greater than 25MPa; 2, bending strength is lower, is 35～40MPa; 3, poor fire can not put out after catching fire certainly.(standard No.: DL/T802.7).

Summary of the invention

The purpose of this utility model is to provide a kind of ring stiffness height, inner wall smooth, the destructive good Novel steel/plastic compound glass steel sleeve of shock resistance.

The purpose of this utility model is to realize like this, described Novel steel/plastic compound glass steel sleeve, formed by outer and internal layer, internal layer is the modified polypropene layer of tubulose, skin is that glass fiber reinforced plastics composite material is outer, and its characteristics are that the outer wall of the modified polypropene layer of described tubulose is bonded with the glass fiber reinforced plastics composite material skin by bonding agent.

Advantage of the present utility model: 1, intensity is high: because skin adopts hot strength and the higher glass fiber reinforced plastics composite material of elastic modelling quantity, so its bending strength, hot strength be more common MPP high (bending strength can reach more than the 190Mpa, and hot strength can reach more than the 160Mpa) all; 2, good-toughness: than the traditional glass steel tubing, moulding the cover inner tube layer because of novel MPP steel is modified polypropylene material, and its toughness is good, the energy low-temperature impact resistance; 3, anti-flammability is good, because skin is glass composite material, can from fire from alkene, can reach the V-2 level; 4, internal layer modified polypropylene material, the coefficient of friction of material own is little, compares the traditional glass steel and significantly reduces, and inwall is smooth smooth simultaneously, and resistance is little, is easy to wear cable, wears cable efficient height; 5, shock resistance destructiveness is good, and because being double-layer structure, in the destroyed situation of skin, internal layer still can be guaranteed the tubing serviceability.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the A part enlarged drawing among Fig. 1.

Among the figure: skin 1, internal layer 2, bond layer 3.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is elaborated:

As depicted in figs. 1 and 2, Novel steel/plastic compound glass steel sleeve described in the utility model, formed by skin 1 and internal layer 2, internal layer 2 is the modified polypropene layer of tubulose, outer 1 is that glass fiber reinforced plastics composite material is outer, its design feature is that the outer wall of the modified polypropene layer of tubulose is bonded with the glass fiber reinforced plastics composite material skin by bonding agent, between described skin and the internal layer by particular adhesive and through together Wrapping formed, described ectonexine is tubular structure, ectonexine adopt the material of different performance make and its between be bond layer 3, to satisfy the different technologies requirement.

Described skin is the planomural structure sheaf, and thickness is 1-15mm.

Described internal layer is the planomural structure sheaf, and thickness is 1-10mm.

Described skin is that glass fiber reinforced plastics composite material is made;

Described internal layer is modified polypropene or modified poly ethylene structure sheaf.

The production method of above-mentioned Novel steel/plastic compound glass steel sleeve the steps include:

Step 1, extrude the modified polypropene layer of tubulose with extruding production line, and inner layer outer wall is carried out surface treatment, spraying one deck high temperature resistant adhesive.

Step 2, the modified polypropene layer of tubulose is fixed on the Wrapping formed machine mould, starts wrapping machine, glass fiber reinforced plastics composite material is coated on the modified polypropene layer of tubulose, and through pressurization, solidify, form bonding firmly steel and mould the compound glass steel sleeve.

Claims

1. Novel steel/plastic compound glass steel sleeve, formed by outer and internal layer, internal layer is the modified polypropene layer of tubulose, and skin is that glass fiber reinforced plastics composite material is outer, and it is characterized in that: the outer wall of the modified polypropene layer of described tubulose is bonded with the glass fiber reinforced plastics composite material skin by bonding agent.
