Embodiment

[0013] Embodiment: A reinforced and modified corrugated electric power sheath tube, its production components and ratio are: by weight, 100 parts of polyethylene or polypropylene or polyvinyl chloride main material needs to add additional auxiliary material glass 10-20 parts of fiber, 20-30 parts of inorganic powder, 2-6 parts of interfacial phase solvent, 6-10 parts of impact modifier, 0.5-0.8 parts of lubricant, 0.5-2 parts of toner;

[0014] The inorganic powder is one or more mixtures of 5-20 parts of calcite masterbatch, 5-20 parts of magnesium carbonate powder, and 5-20 parts of calcium carbonate powder.

[0015] The interfacial phase solvent is a mixture of a titanate coupling agent and a silane coupling agent and a maleic anhydride-grafted polyolefin resin, wherein the maleic anhydride-grafted polyolefin resin corresponds to the selected main material, namely When the main material is polyethylene, use maleic anhydride grafted polyethylene; when the main material is po...

Abstract

The invention discloses a reinforced and modified corrugated power protection sleeve, which is produced by taking polyethylene or polypropylene or polyvinyl chloride as a main material and adding glass fibres, inorganic powder, an interface phase solvent, an impact modifier, a lubricant and toner to the main material. Among the components, the glass fibres and the inorganic powder can multiply the ring stiffness of a tubular product and reduce the manufacturing costs of the product, wherein the inorganic powder is one or a mixture of calcite master batch, a magnesium carbonate powder material or a calcium carbonate powder material; the interface phase solvent enables the components to be fully blended so as to facilitate granulation; and the impact modifier is a mixture of an acrylics impact modifier ACR and a chlorinated polyethylene impact modifier CPE, wherein the acrylics impact modifier ACR is excellent in workability and good in impact resistance and weather resistance and can be stable for a long time, the chlorinated polyethylene impact modifier CPE is a rubber body and is high in elasticity and excellent in impact resistance but is poor in workability and inferior to acrylics in weather resistance, but the synergistic effect of the two impact modifiers allows the good short-term impact resistance of the tubular products to be developed, and can ensure the long-term impact resistance of the tubular products.

Description

technical field [0001] The invention belongs to the technical field of production of electric corrugated sheath pipes, in particular to a reinforced and modified corrugated electric sheath pipe. Background technique [0002] The power sheath tube is mainly used as a cable sheath to protect the cable from external damage and ensure the safety of electricity use. Most of the power sheath tubes are buried in the ground. Plastic pipes have replaced the original metal pipes. Due to the harsh use environment, It is necessary to strengthen and modify the plastic material so that it has a high ring stiffness to resist external loads; it has enough Vicat softening point to buffer the deformation of the sheath tube caused by heat during the use of the cable. The main disadvantage of the power sheath pipe in the prior art is that the ring rigidity is not enough, and it is easily deformed or even broken by external pressure, which brings safety hazards to the power pipeline.
