CN2508351Y - Insulation band for longitudinally wrapping fire-resistant wire - Google Patents

Abstract

The utility model discloses an insulating tape for longitudinally wrapping a fire resistant electric wire. The utility model is formed by adhesively bonding and compounding mica paper and a plastic thin film through bonding agent. Compared with an existing mica tape, the production cost is greatly reduced, the utility model has the obvious characteristics that the plastic thin film is thoroughly replaced with glass cloth, and the utility model is specially used for longitudinally wrapping and producing the fire proof and fire resistant electric wire and an electric cable, and the social benefit is remarkable.

Description

The vertical bag insulating tape of a kind of fire-resistant wires

The vertical bag of a kind of fire-resistant wires of the utility model relates to fire-resistant wires, cable insulation material technical field with insulating tape, is applied to the insulation of electric wire, cable.

Fire-resistant wires, the cable of domestic production at present all adopt mica tape as insulating barrier, its processing method all adopts wrapped mode, so the tension intensity to mica tape has very high requirement, existing mica has two kinds, a kind of is to use the glass wool cloth reinforcement, another kind is with glass fiber (no latitude) reinforcement, its pulling force is mainly from glass fiber and glass wool cloth, its production difficulty is big, the cost height, so can't be used widely as fire-resistant, flame-proof wire, the cable of insulator with mica tape, particularly civil area.

The vertical bag of a kind of fire-resistant wires of the utility model is with the purpose of insulating tape: overcome the existing expensive defective of mica tape price, a kind of simplified manufacturing technique is provided, faster production, reduce production costs, can keep its high temperature resistant and insulation property again and produce fire-resistant, flame-proof wire, cable insulating tape by vertical packet technology.

The vertical bag of a kind of fire-resistant wires of the utility model with insulating tape in order to achieve the above object, its technology is to realize like this, its structure is by mica paper, plastic film is formed, it is characterized in that: one deck mica paper and one to two layer of plastic film are compound, when taking two layers of plastic film, mica paper is located between two layers of plastic film.

The vertical bag of a kind of fire-resistant wires of the utility model has adopted above-mentioned technology with insulating tape, plastic film has thoroughly replaced glass fiber and glass wool cloth, compare with existing mica tape, its tension intensity, resistance to elevated temperatures and insulation property remain unchanged, production cost descends 50%, the utmost point has promotional value, and social benefit is obvious.

The vertical bag of a kind of fire-resistant wires of the utility model is further described with insulating tape with two embodiment below in conjunction with accompanying drawing:

Fig. 1 is one deck mica tape, the compound structural representation of layer of plastic film:

Fig. 2 is one deck mica tape, two layers of structural representation that plastic film is compound;

Among the figure, 1---mica tape, 2---plastic film, 3---adhesive

Embodiment one:

Mica tape among Fig. 1 (1) is compound by adhesive (3) and layer of plastic film (2).

Embodiment two:

Mica tape among Fig. 2 (1) is located between two layers of plastic film, and is compound by adhesive (3) and two layers of plastic film.

In sum, the vertical bag of a kind of fire-resistant wires of the utility model is widely used with insulating tape, and particularly civil area has obvious practicability, and market capacity is big, and economic benefit is obvious.

Claims (2)

1. vertical bag of a kind of fire-resistant wires of the utility model used insulating tape, form by mica paper (1), plastic film (2), binding agent (3), it is characterized in that: the structure of mica paper (1) and 1-2 layer plastic film (2) is binding agent (3) between mica paper (1) and the plastic film (2).

2. the vertical bag of a kind of fire-resistant wires according to claim 1 is used insulating tape, and it is characterized in that: mica paper (1) is located between the upper and lower two layers of plastic thin films (2).
