Cable support made of composite materials and method for manufacturing cable support

Abstract

The invention particularly relates to a cable support made of composite materials and a method for manufacturing the cable support, and belongs to the technical field of composite materials. The cable support made of the composite materials comprises, by weight, 25-40 parts of polyacrylic acid resin, 10-20 parts of ethylene propylene rubber, 15-30 parts of phenol formaldehyde resin, 15-25 parts of carbon fibers, 15-25 parts of alkali-free long glass fibers, 8-20 parts of aluminum hydroxide, 2-10 parts of adhesive, 5-12 parts of magnesium hydroxide, 6-15 parts of talc powder and 1-6 parts of plasticizers. The method includes mixing and stirring the polyacrylic acid resin, the phenol formaldehyde resin, the carbon fibers and the alkali-free long glass fibers with one another; adding the residual materials into the polyacrylic acid resin, the phenol formaldehyde resin, the carbon fibers and the alkali-free long glass fibers and uniformly mixing the residual materials, the polyacrylic acid resin, the phenol formaldehyde resin, the carbon fibers and the alkali-free long glass fibers with one another to obtain mixtures; solidifying the mixtures and then smashing the mixtures to obtain granular materials; arranging the granular materials in molds for the cable support and manufacturing the required cable support by the aid of a hot-press forming process. The cable support and the method have the advantages that the cable support is insulating, fireproof and anticorrosion and is high in strength, and the like.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a composite material cable support and a preparation method thereof. Background technique [0002] Composite materials are materials with new properties composed of two or more materials with different properties through physical or chemical methods. Various materials learn from each other in terms of performance and produce synergistic effects, so that the comprehensive performance of the composite material is better than that of the original constituent materials to meet various requirements. The matrix materials of composite materials are divided into two categories: metal and non-metal. Commonly used metal substrates are aluminum, magnesium, copper, titanium and their alloys. Non-metallic substrates mainly include synthetic resin, rubber, ceramics, graphite, carbon, etc. Reinforcement materials mainly include glass fiber, carbon fiber, boron fiber, ...

AI Technical Summary

Problems solved by technology

Composite materials can also be applied to the cable brackets used for erecting cables. The previous ones were mainly angle iron cable brackets, but the following problems have always existed in the production and use of angle iron cable brackets: 1. Energy consumption in the production process of angle iron cable brackets Large, many processes, long cycle

2. It is easy to rust and corrode, the mechanical bearing capacity is reduced, and the service life is greatly reduced, especially in the environment of subways, tunnels, rainy and humid and coastal salt fog weather

3. The eddy current phenomenon occurs between the cable and the angle iron cable bracket, resulting in the loss of electric energy and the increase of cable cost, which seriously affects the safety of electric power and communication facilities
