Embodiment 1

[0022] The composition and mass percentage of SMC composite materials are as follows:

[0023] Unsaturated polyester resin is 18%, low-shrinkage additive is 8%, flame-retardant filler is 50%, glass fiber is 20%, and other additives are 4%. The other additives are curing agents, release agents or thickeners.

[0024] The preparation process is:

[0025] (1) Put unsaturated polyester resin, low-shrinkage additives, other additives, and flame-retardant fillers into a beater to make resin paste;

[0026] (2) adding glass fibers to the resin paste, stirring at a low speed of less than 50r / min for 15 minutes to obtain a molding material;

[0027] (3) Inject the molding material into the mold, heat to 120°C, increase the pressure to 1.5 times the atmospheric pressure, and keep the temperature and air pressure for 20 minutes;

[0028] (4) Keep the air pressure, and release the mold after naturally cooling to normal temperature to obtain a molded part.

Embodiment 2

[0030] The composition and mass percentage of SMC composite materials are as follows:

[0031] Unsaturated polyester resin is 22%, low shrinkage additive is 10%, flame retardant filler is 45%, glass fiber is 20%, and other additives are 3%. The other additives are curing agents, release agents or thickeners.

[0032] The preparation process is:

[0033] (1) Put unsaturated polyester resin, low-shrinkage additives, other additives, and flame-retardant fillers into a beater to make resin paste;

[0034] (2) adding glass fibers to the resin paste, stirring at a low speed of less than 50r / min for 15 minutes to obtain a molding material;

[0035] (3) Inject the molding material into the mold, heat to 150°C, increase the pressure to 1.5 times the atmospheric pressure, and keep the temperature and air pressure for 10 minutes;

[0036] (4) Keep the air pressure, and release the mold after naturally cooling to normal temperature to obtain a molded part.

Embodiment 3

[0038] The composition and mass percentage of SMC composite materials are as follows:

[0039] Unsaturated polyester resin is 20%, low-shrinkage additive is 8%, flame-retardant filler is 50%, glass fiber is 18%, and other additives are 4%. The other additives are curing agents, release agents or thickeners.

[0040] The preparation process is:

[0041] (1) Put unsaturated polyester resin, low-shrinkage additives, other additives, and flame-retardant fillers into a beater to make resin paste;

[0042] (2) adding glass fibers to the resin paste, and stirring at a low speed of less than 60r / min for 12 minutes to obtain a molding material;

[0043] (3) Inject the molding material into the mold, heat to 100°C, increase the pressure to 2 times the atmospheric pressure, and keep the temperature and air pressure for 30 minutes;

[0044] (4) Keep the air pressure, and release the mold after naturally cooling to normal temperature to obtain a molded part.

Abstract

The invention relates to the technical field of cable burying, and particularly provides a novel cable bracket hoop and a preparation method thereof. The novel cable bracket hoop is a molded part of an even SMC composite material; a reserved inserting hole is formed in the novel cable bracket hoop; the novel cable bracket hoop is connected with a cable bracket upright post through a bolt made of the SMC composite material; and the SMC composite material comprises the following components in percentage by mass: 18%-22% of unsaturated polyester resin, 8%-10% of a low-shrinkage additive, 45%-50% of a flame-retardant filler, 18%-20% of glass fiber and 3%-4% of other additives. The preparation method comprises the following steps: firstly preparing resin paste in preparation; and adding the glass fiber, stirring, heating, pressurizing and molding. The novel cable bracket hoop disclosed by the invention is energy-saving, environmentally-friendly, long in service life, good in flame retardant property, free of eddy, good in safety performance.

Description

technical field [0001] The invention relates to the technical field of cable entry into the ground, and specifically provides a novel cable bracket hoop and a preparation method thereof. Background technique [0002] With the vigorous development of my country's economic construction, the power industry has been driven to revive. The rapid economic development has led to the large-scale construction of highways and high-speed railways, and various facilities and equipment that are compatible with transmission lines have also been widely developed and utilized. Large-scale power transmission lines are transported by cables. Among them, the cable bracket is an important part of the transmission cable used in the electric power industry. Transmission and output of cables in underground trenches and cable tunnels. A hoop is provided on the cable bracket to fix the cable. The national cable laying code requires that the cables must be fixed with hoops every 10 meters during th...
