Embodiment 1

[0030] The modified flame-retardant composite resin for coating the surface of mine metal pipes of the present invention comprises the following components in parts by weight: 80-100 parts of a mixture of polyethylene and polypropylene

[0031] 5-10 parts of terpene resin,

[0032] 5-10 parts of zinc oxide,

[0033] 3-6 parts of ethoxylated alkylamine,

[0034] 2 to 5 parts of paraffin,

[0035] 1-2 parts of trinonylphenyl phosphite.

[0036] In this embodiment, the terpene resin is used as a modifier to improve the fluidity of the coating, and to improve the adhesion, impact toughness, environmental cracking resistance, fatigue resistance and hardness of the steel base; zinc oxide is used as a stabilizer to improve the environmental weather resistance ; Ethoxylated alkylamine is antistatic agent, which improves corrosion resistance and service life; paraffin wax is used as leveling agent, which increases leveling property and smooth surface, forming a flat and smooth film ...

Embodiment 2

[0049] This embodiment provides a method for preparing the modified flame retardant composite resin, comprising the following steps:

[0050] (1) Weigh each component according to the formula and mix for 10-20 minutes;

[0051] (2) Put the mixed material into the granulator for extrusion granulation;

[0052] (3) Sieve and size the granules extruded from the granulator;

[0053] (4) Dry the obtained granules at a temperature of 60-80° C. for 4-6 hours.

[0054] Described formula adopts the formula described in embodiment 1.

[0055] In this embodiment, the terpene resin is used as a modifier to improve the fluidity of the coating, and to improve the adhesion, impact toughness, environmental cracking resistance, fatigue resistance and hardness of the steel base; zinc oxide is used as a stabilizer to improve the environmental weather resistance ; Ethoxylated alkylamine is antistatic agent, which improves corrosion resistance and service life; paraffin wax is used as leveling ...

Embodiment 3

[0057] see figure 1 , the present embodiment provides a metal pipe for mines, including a metal pipe body 2 and a modified flame-retardant composite resin coating coated on the surface of the metal pipe body, the modified flame-retardant composite resin coating includes an inner coating 12 and outer coating 11. The modified flame retardant composite resin coating can be prepared by using the modified flame retardant composite resin described in Example 1 above.

[0058] The thickness of the modified flame-retardant composite resin coating is preferably 0.1-3mm.

[0059] Among the various components involved in the modified flame-retardant composite resin coating coated on the metal pipe body, the terpene resin is used as a modifier to improve the fluidity of the coating and the adhesion to the steel base. Impact toughness, environmental cracking resistance, fatigue resistance and hardness; zinc oxide is a stabilizer to improve environmental weather resistance; ethoxylated al...

Abstract

The invention discloses a modified flame-retardant composite resin and a preparation method thereof. The resin comprises the following components in parts by weight: 80-100 parts of a mixture of polyethylene and polypropylene, 5-10 parts of terpene resin, zinc oxide 5-10 parts, 3-6 parts of ethoxylated alkylamine, 2-5 parts of paraffin, 1-2 parts of trinonylphenyl phosphite. The modified flame-retardant composite resin for coating the surface of mine metal pipes has good flame-retardant effect and can prevent metal pipes from corroding too quickly, and the metal pipes coated with the resin are suitable for underground mine operations.

Description

technical field [0001] The invention relates to polymer materials, in particular to a modified flame-retardant composite resin, a metal pipe for mines and a preparation method thereof. Background technique [0002] In mine operations, 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; in addition, the metal pipes are heavy, inconvenient to transport, and the future maintenance is quite cumbersome. At present, some enterprises have used plastic polyethylene pipes instead of metal pipes. Although this is convenient for transportation, the strength of polyethylene plastic pipes is not enough, and there will be safety hazards under the condition of high bottom pressure. Contents of the invention [0003] The invention aims to provide a modified flame-retardant composite resin, which can be used to coat the surface of metal pipes, in order to solve the problem that the surface ...
