preparation example Construction

[0013] The invention provides a method for preparing a cold-resistant cable, comprising:

[0014] 1) ultrasonically vibrate molecular sieves, potassium titanate whiskers, porous starch and water, and then dry to prepare a mixture;

[0015] 2) Soak the mixture, bis[2-(2-butoxyethoxy)ethyl adipate] and dibutyl adipate, and then filter to obtain the anti-cold additive;

[0016] 3) Mixing natural rubber, polyvinyl chloride, dioctyl terephthalate, hydroxymethyl starch, bentonite, nano-titanium dioxide, silicone oil, sulfur and the anti-cold auxiliary agent, and then coating the outside of the cable core To make the cold-resistant cable.

[0017] In step 1) of the present invention, the consumption of each material can be selected in a wide range, but in order to further improve the cold resistance of the cable insulation layer, preferably, in step 1), molecular sieve, potassium titanate whisker, The weight ratio of porous starch to water is 50:4-8:10-16:100-200.

[0018] In step...

Embodiment 1

[0027] 1) Molecular sieves, potassium titanate whiskers, porous starch and water were subjected to ultrasonic vibration according to the weight ratio of 50:6:13:150 (ultrasonic frequency is 28KHz, oscillation time is 50min), and then dried (drying temperature was 110°C, The drying time is 3h) to make the mixture;

[0028] 2) Soak the mixture, bis[2-(2-butoxyethoxy)ethyl adipate] and dibutyl adipate in a weight ratio of 100:15:24 (soaking temperature is 40°C, The soaking time is 13h), and then filtered to obtain the anti-cold auxiliary agent A1.

Embodiment 2

[0030] 1) Molecular sieves, potassium titanate whiskers, porous starch and water were ultrasonically oscillated in a weight ratio of 50:4:10:100 (ultrasonic frequency 25KHz, oscillating time 40min), and then dried (drying temperature 100°C, The drying time is 4h) to make the mixture;

[0031] 2) Soak the mixture, bis[2-(2-butoxyethoxy)ethyl adipate] and dibutyl adipate in a weight ratio of 100:15:24 (soaking temperature is 35°C, The soaking time is 16h), and then filtered to obtain the anti-cold auxiliary agent A2.

Abstract

The invention discloses a cold-resistant cable and a preparation method thereof. The preparation method comprises the steps: (1) carrying out ultrasonic oscillation on a molecular sieve, a potassium titanate whiskers, porous starch and water, and then, carrying out drying to prepare a mixture; (2) soaking the mixture, bis(2-(2-butoxyethoxy)ethyl)adipate and dibutyl adipate, and then, carrying outfiltration to prepare a cold-resistant auxiliary; and 3) mixing natural rubber, polyvinyl chloride, dioctyl terephthalate, hydroxymethyl starch, bentonite, nanometer titania, silicon oil, sulfur and the cold-resistant auxiliary, and then, wrapping the outside of a cable core to prepare the cold-resistant cable. A cold-resistant cable layer has excellent cold resistance, and meanwhile, the preparation method has the advantages of simple process and available raw materials.

Description

technical field [0001] The invention relates to cables, in particular to a cold-resistant cable and a preparation method thereof. Background technique [0002] The cable is mainly composed of the following four parts. Conductive wire core: made of high conductivity material (copper or aluminum). According to the requirements of cable softness under laying conditions, each wire core may be twisted by a single wire or multiple wires; insulation layer: the insulation material used for cables should have high insulation resistance and high breakdown electric field strength, low dielectric loss and low dielectric constant. Sealing sheath: protect the insulated wire core from mechanical damage, moisture, moisture, chemicals, light, etc. For moisture-prone insulation, lead or aluminum extruded sealing sheaths are generally used; protective covering: used to protect the sealing sheath from mechanical damage. [0003] Although the existing insulation layer can meet the existing d...
