Example Embodiment

[0014] A water-blocking flame-retardant composite flexible cable sheath material suitable for humid environments, prepared from the following parts by weight (kg) of raw materials: polyether polyurethane 100, diethyl aluminum phosphinate 20, melamine cyanurate 17, Aluminum titanate 4.3, PVC50, crosslinking agent TAIC1.6, calcium stearate 6, acetyl tributyl citrate 20, polydimethylsiloxane 3, glyceryl monostearate 3, antimony trioxide 5 , Emulsified asphalt 4, Bisphenol A polycarbonate 4, Talc 8.

[0015] The water-blocking flame-retardant composite flexible cable sheath material suitable for humid environment is made by the following specific steps:

[0016] (1) Put aluminum diethylphosphinate, melamine cyanurate, aluminum titanate, and half of calcium stearate into a high-speed mixer, stir at 1000 rpm at room temperature for 10 minutes, and then heat Stir at 80℃ for 15 minutes at a speed of 1200 rpm to obtain a uniformly dispersed composite flame retardant; place the polyether po...

Abstract

The invention discloses a preventing water and inflaming retarding composite flexible cable sheath material used in wet environment. The flexible cable sheath material is characterized by comprising the following raw materials: be weight, 100-102 parts of polyether urethane, 20-21.5 parts of aluminum diethylphosphinate, 17-18 parts of melamine cyanurate, 4.3-4.5 parts of aluminium titanate, 50-52 parts of PVC, 1.6-1.8 parts of cross-linking agent TAIC, 6-7 parts of calcium stearate, 20-22 parts of acetyl tributyl citrate, 3-4 parts of polydimethylsiloxane, 3-4 parts of glycerin monostearate, 5-7 parts of antimonous oxide, 4-5 parts of emulsified asphalt, 4-5 parts of bisphenol A polycarbonate and 8-10 parts of talcum powder. The prepared product has good water resistance, good mud resistance, good decay resistance, good flame resistance, and has soft material. So that the prepared cable sheath has large bending amplitude, is especially suitable for the places where have high fireproofing requirement in coastal region having high humidity, and is especially suitable for ocean engineering.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a water-blocking and flame-retardant composite flexible cable sheath material suitable for humid environments and a preparation method thereof. Background technique [0002] Thermoplastic polyurethane is an elastomer material polymerized by diisocyanate, polyol and chain extender. It has the characteristics of high strength, high elasticity, wear resistance, oil resistance, weather resistance, low temperature resistance and softness. It is a combination of any rubber and plastic. not fully equipped. According to the molecular structure, it can be divided into two types: polyether type and polyester type. Due to the complicated use environment of the cable, the required service life is more than 10 years, while the polyester type polyurethane has poor high temperature hydrolysis resistance and low temperature flexibility. The resistance is not as good as polyether type,...
