Embodiment 1

[0036] The present embodiment is flame retardant additive, and the preparation process of described flame retardant additive is as follows:

[0037] S1: Add diphenylsilanediol, toluene, and triethylamine to a four-necked flask equipped with a condensing reflux device, a constant pressure dropping funnel, a stirrer, and a thermometer, under the condition of a stirring speed of 300r / min Stir until the solid is completely dissolved to obtain a reaction solution a; control the ratio of diphenylsilanediol, toluene, and triethylamine to 117.14g: 300mL: 82.32g;

[0038] S2: Add phosphorus oxychloride to dry chloroform, and stir until the solid is completely dissolved at a stirring speed of 300r / min to obtain reaction solution b; control the dosage ratio of phosphorus oxychloride and chloroform to 87.50g: 200mL;

[0039] S3: Add the reaction solution b to the four-necked flask, start stirring and circulate the condensed water, add it dropwise to the reaction solution a under the cond...

Embodiment 2

[0042] The present embodiment is flame retardant additive, and the preparation process of described flame retardant additive is as follows:

[0043] S1: Add diphenylsilanediol, toluene, and triethylamine to a four-necked flask equipped with a condensing reflux device, a constant pressure dropping funnel, a stirrer, and a thermometer, under the condition of a stirring speed of 500r / min Stir until the solid is completely dissolved to obtain a reaction solution a; control the ratio of diphenylsilanediol, toluene, and triethylamine to 117.14g: 300mL: 82.32g;

[0044] S2: Add phosphorus oxychloride to dry chloroform, and stir until the solid is completely dissolved at a stirring speed of 500r / min to obtain a reaction solution b; control the dosage ratio of phosphorus oxychloride and chloroform to 87.50g: 200mL;

[0045] S3: Add the reaction solution b into the four-necked flask, start stirring and circulate the condensed water, add it dropwise to the reaction solution a under the ...

Embodiment 3

[0048] This embodiment is a production process of a flame-retardant fireproof rope mesh line, which includes the following steps:

[0049] Step 1: Weigh 80 parts of high-density polyethylene, 0.1 part of antioxidant, 0.3 part of ultraviolet absorber, 0.1 part of dispersant, 1 part of silane coupling agent, 2 parts of titanium dioxide and the barrier resin from Example 1 according to parts by weight. 2 parts of fuel additives; the antioxidant is antioxidant 168; the ultraviolet absorber is light stabilizer 744; the dispersant is a mixture of paraffin and calcium stearate in a mass ratio of 1:1; The coupling agent is silane coupling agent KH-550;

Abstract

The invention discloses a flame-retardant fireproof rope net wire and a production process thereof, and relates to the field of fireproof rope net wires, high-density polyethylene, an antioxidant, an ultraviolet light absorber, a dispersing agent, a silane coupling agent, titanium dioxide and a flame-retardant additive are uniformly mixed to obtain a mixture, the mixture is added into an extruder for extrusion granulation, flame-retardant plastic particles are obtained, then the flame-retardant plastic particles are subjected to injection molding, and the flame-retardant plastic particles are dragged and stretched into filaments so that the flame-retardant fireproof rope net wire is obtained. The antioxidant and the ultraviolet light absorber are added to improve the antioxidant and anti-aging performance of the rope net wire and prolong the service life of the rope net wire, the flame retardant additive is added to improve the fireproof and flame-retardant performance of the rope net wire, and the flame retardant additive has the synergistic effect of bromine and phosphorus elements and has excellent flame-retardant and fireproof effects. The prepared flame-retardant fireproof rope net wire is not easy to ignite, is slow in combustion spreading speed and high in extinguishing speed after being ignited, and has excellent fireproof and flame-retardant properties.

Description

technical field [0001] The invention relates to the field of fireproof rope netting wire, in particular to a flame-retardant fireproof rope netting wire and a production process thereof. Background technique [0002] With the development of society, people pay more and more attention to safety. With the rapid development of high-rise buildings, highways, railway construction, and the increasing number of large-scale key engineering projects, people pay more and more attention to safety issues. The requirements for the quantity and quality of protective nets are increasing day by day. Safety nets are necessary protective equipment for construction workers on construction sites, and their quality directly affects the safety of construction workers; [0003] At present, most of the rope nets in our country are barbed wire or ordinary fiber protective nets. Ordinary fiber nets have low strength, are not wear-resistant, and are easy to puncture so that the safety of the protectiv...
