Insulation thermal shrinkage plastic and insulation thermal shrinkage rubber sleeve

Abstract

The invention provides an insulation thermal shrinkage plastic, and belongs to the filed of plastics. The insulation thermal shrinkage plastic comprises polyolefin resin, a flame-retardant agent, an antioxidant, methyltin mercaptide, sebacic acid di-(2-ethyl) hexyl acetate, high-phenyl silicane rubber, a plastic processing aid, borax and a smoke suppressant, wherein the smoke suppressant is a mixture of molybdenum trioxide and zinc aluminate. The insulation thermal shrinkage plastic has the advantages that when the thermal shrinkage is performed, the higher temperature can be borne, and the burning does not occur; in the thermal shrinkage process, the black smoke is avoided, the smelly pungent odor is avoided, and the environment-friendly effect is realized. The invention also provides an insulation thermal shrinkage rubber sleeve; the insulation thermal shrinkage rubber sleeve is used for quick connection in the electric wire connecting process, the insulation effect is better, and the black smoke is avoided.

Description

Technical field [0001] The invention relates to the field of plastics and plastic products, in particular to an insulating heat-shrinkable plastic and an insulating heat-shrinkable rubber sleeve. Background technique [0002] When two sections of wires need to be connected, the two sections of wires are wound by using insulating tape, but this connection method is not stable enough, and the insulating tape may fall off or be loosely wrapped, which is prone to leakage. [0003] In the prior art, insulating heat-shrinkable rubber sleeves are also used to realize wire connection. However, when the existing insulating heat-shrinkable rubber sleeves are in use, when heat acts on the plastic, if the temperature is too high, the plastic will burn easily, and at the same time In the case of burning, high-temperature baking plastic will also produce larger black smoke, which has a pungent smell, which is not conducive to the physical and mental health of the operators. Summary of the inven...

Problems solved by technology

[0002] When it is necessary to connect two sections of wires, the two sections of wires are wrapped with insulating tape, but this connection method is not stable enough, and the insulating tape may fall off or be not wrapped tightly, which is prone to leakage

[0003] In the prior art, insulating heat-shrinkable rubber sleeves are also used to realize wire connection, but when the existing insulating heat-shrinkable rubber sleeves are used, when the heat acts on the plastic, if the temperature is too high, it is easy to cause the plastic to burn. In the case of burning, high-temperature baking plastic will also produce relatively large black smoke, which has a pungent taste and is not conducive to the physical and mental health of operators.
