Problems solved by technology

The traditional method is to use metal pipes to operate, but the humidity inside the mine is high, and the metal pipes will be corroded for a long time
At present, some enterprises have used plastic polyethylene pipes instead of metal pipes, which can avoid corrosion, but the strength of polyethylene plastic pipes is not enough, and there will be safety hazards under the condition of high bottom pressure

Embodiment 1

[0029] Embodiment 1 of the present invention provides a modified flame-retardant composite resin, comprising the following components in parts by weight:

[0030] 5-10 parts of terpene resin,

[0031] 5-10 parts of zinc oxide,

[0032] 3-6 parts of ethoxylated alkylamine,

[0033] 2 to 5 parts of paraffin,

[0034] 1-2 parts of trinonylphenyl phosphite.

[0035] The modified flame-retardant composite resin provided in this embodiment is coated on the surface of the metal pipe, which can effectively prevent the corrosion of the metal pipe. The actual test data shows that the flame retardant effect can reach V0 level, and it can be coated on the surface of the metal pipe to form a smooth, uniform color coating without defects such as pinholes and scars, which can prevent the corrosion of metal pipes and meet the requirements of mine pipes. National requirements are conducive to eliminating potential safety hazards.

[0036] In this embodiment, in order to further improve th...

Embodiment 2

[0045] This example provides a method for preparing a modified flame-retardant composite resin, the formula of which is as follows:

[0046] 5-10 parts of terpene resin,

[0047] 5-10 parts of zinc oxide,

[0048] 3-6 parts of ethoxylated alkylamine,

[0049] 2 to 5 parts of paraffin,

[0050] 1-2 parts of trinonylphenyl phosphite.

[0051] Described preparation method comprises the steps:

[0052] (1) Weigh each component of the ratio and mix them evenly;

[0053] (2) Put the components uniformly mixed in step (1) into a granulator for extrusion granulation;

[0054] (3) Sieve and size the granules extruded from the granulator;

[0055] (4) Dry the sized particles at 60-80°C for 4-6 hours to make a modified flame-retardant composite resin material with a particle size of 30-60 mesh.

[0056] The modified flame-retardant composite resin prepared by the method provided in this example is coated on the surface of the metal pipe to form a dense coating, which can effective...

Embodiment 3

[0066] see figure 1 , the pipeline for mine water of the present embodiment includes a metal pipe body 2 and a modified flame-retardant composite resin coating coated on the surface of the metal pipe, and the modified flame-retardant composite resin coating includes an inner coating 12 and an outer coating For layer 11, the modified flame-retardant composite resin is the resin described in Example 1.

[0067] The pipeline for mine water in this embodiment is coated with a modified flame-retardant composite resin coating on the surface of the metal pipe, which can effectively prevent the corrosion of the metal pipe, and because of the support of the metal pipe, the strength is relatively high, which can meet the requirements for use in mines. , the mine water pipeline surface resistance of the present invention is 1 × 10 3 ~1×10 5 , the flame retardant effect can reach V0 level, the inner and outer coatings are smooth, the color is uniform, there are no defects such as pinhol...

Abstract

The invention discloses a modified flame-retardant composite resin, a pipeline for pit water and a preparation method thereof. The resin comprises the following components in parts by weight: 80-100 parts of polyethylene and polypropylene mixture, 40-50 parts of aluminum hydroxide or magnesium hydroxide, 5-10 parts of polycarbonate, 5-10 parts of carbon black, 3-6 parts of ethoxylated alkylamine and 1-2 parts of trinonylphenyl phosphite. The pipeline for pit water comprises a metal pipe body and a modified flame-retardant composite resin coating applied onto the surface of the metal pipe body. The pipeline for pit water disclosed by the invention can effectively prevent the metal pipe from corrosion, has high strength ratio, and can satisfy the requirements for application in pits.

Description

technical field [0001] The invention relates to a pipeline for mine water, in particular to a modified flame-retardant composite resin, a pipeline for mine water and a preparation method thereof. Background technique [0002] Mine water contains fine particles, salt, chloride ions, etc. Steel pipes are prone to corrosion and wear. Mine water pipes used in mines must be antistatic and anti-burning, and mine water pipes used outside mines must be weather-resistant. The traditional method is to use metal pipes to operate, but the humidity inside the mine is high, and the metal pipes will be corroded for a long time. At present, some enterprises have used plastic polyethylene pipes instead of metal pipes, which can avoid corrosion, but the strength of polyethylene plastic pipes is not enough, and it will cause safety hazards when the bottom pressure is high. Contents of the invention [0003] The invention aims to provide a modified flame-retardant composite resin for coating...
