Problems solved by technology

At present, anti-ant and rodent-proof sheathing materials are usually treated with trace toxin additives, which are fatal to ants or mice, and have little impact on the human body, such as spicy agents, etc., but the disadvantage is that they are not long-lasting. After being made into a cable, it will volatilize after being used outdoors for about 3 months, and cannot function for a long time, and the sheathing process will produce a pungent smell

Abstract

The invention provides an anti-termite and anti-rat cable which comprises a cable core and a sheath wrapping the cable core. The sheath is prepared from the following raw materials in parts by weight: 10-20 parts of porous silicon dioxide / carboxylated polystyrene double-layer hollow spheres, 2-7 parts of n-nonanoic acid vanilloyl amide, 100-200 parts of polyethylene, 2-5 parts of a composite flame retardant, 1-2 parts of a toughening agent, 0.5-1.5 parts of an antioxidant, 0.1-1 part of a dispersing agent and 2-5 parts of microcrystalline cellulose. The porous silicon dioxide / carboxylated polystyrene double-layer hollow ball with a large number of mesopores in the surface is prepared, the inner layer is a wall layer containing a carboxyl structure, amino in Nonivamide and carboxyl in the wall layer of the inner layer are condensed, the slow release effect is achieved, and the long-acting repelling effect on mice and ants is achieved; and the composite flame retardant, the flexibilizer and other modified materials are adsorbed on the surface, so that the comprehensive performance of the polyethylene material is effectively improved, and the anti-termite and anti-rat cable has a wide application prospect.

Description

technical field [0001] The invention relates to the field of cables, in particular to an ant-proof cable and a preparation method thereof. Background technique [0002] Cables and optical cables are collectively referred to as cables. At present, most cable sheathing materials are made of polyethylene materials, which are easily eaten by ants and mice. Therefore, it is necessary to develop ant-proof and rodent-proof sheathing materials. At present, anti-ant and rodent-proof sheath materials are usually treated with trace toxin additives, which are fatal to ants or mice, and have little effect on the human body, such as spicy agents, etc., but the disadvantage is that they are not long-lasting. After being made into a cable, it will volatilize after about 3 months of outdoor use, and cannot function for a long time, and the sheathing process will produce a pungent smell. Contents of the invention [0003] The purpose of the present invention is to propose an ant-proof cab...
