Abstract
The invention discloses an antistatic polyethylene mining pipe parent stock and a preparation method thereof. The stock is prepared by the raw materials with the following weight portions: 90 to 110 portions of polyethylene, 5 to 20 portions of metal particles, 5 to 30 portions of flame retardant, 1 to 8 portions of stabilizer, 0.5 to 3 portions of surfactant and 4 to 20 portions of carbon black. By adding metal particles in the antistatic polyethylene mining pipe parent stock, the invention can decrease the resistance of antistatic polyethylene mining pipe parent stock and thus decreasing the static rate of polyethylene mining tubular parent stock. According to the experimental detection, adding metal particles into polyethylene can decrease the resistance of antistatic polyethylene mining pipe parent stock to below 50 omega, far lower than the resistance of prior antistatic polyethylene mining pipe parent stock added with antistatic material. The amount of added metal particles is 5 to 20, thus not only guaranteeing the antistatic performance of polyethylene pipe but also little affecting the toughness, strength and corrosion resistance of polyethylene pipe.
Description
Technical field
The present invention relates to a kind of antistatic master batch, particularly a kind of electrostatic resistant polythene mining tube mother material and preparation method thereof.
Background technology
Material alkene IXI is easy to generate the critical defect that spark, easy-to-rust, quality heavily wait because of there is collision in metal tube, and present mining pipe is all being changed to plastics tubing substantially.But plastics tubing in use easily produces static, has so just restricted the use range of plastics tubing greatly, in the hole, ore deposit, easily produces electrostatic plastics tubing very easily initiation fire or gas explosion especially.The making method of existing antistatic plastic pipe adopts in base-material more is added various antistatic materials and solves, and as carbon black etc., but in actual applications, the resistance of pipeline is still higher, and antistatic effect still is not very desirable, can't satisfy the requirement of mining pipe.
Summary of the invention
The technical problem to be solved in the present invention is, good electrostatic resistant polythene mining tube mother material of a kind of antistatic effect and preparation method thereof is provided, and can overcome the deficiencies in the prior art.
Technical scheme of the present invention is: it is to be made by following quality proportion raw material:
90～110 parts of polyethylene, 5～20 parts of metallic particles, 5～30 parts of fire retardants, 1～8 part of stablizer, 0.5～3 part in tensio-active agent, 4～20 parts of carbon blacks.
Described metallic particles is shot copper or aluminum shot.
Described fire retardant is aluminium hydroxide, antimonous oxide or magnesium hydroxide.
Described stablizer is antioxidant 1010, oxidation inhibitor 168 or antioxidant 2246 etc.
Described tensio-active agent is a silane coupling agent.
It is that metallic particles is carried out surface-active-treatment with tensio-active agent; metallic particles after will handling then and other do not drop into high-speed mixer with raw material by the quality proportioning; under 70～100 ℃ temperature, mix, obtain electrostatic resistant polythene mining tube mother material by the dual-screw pelletizer granulation at last through high-speed mixer.
Be case problem HU compared with the prior art, the present invention is by adding metallic particles in electrostatic resistant polythene mining tube mother material, so just can reduce the resistance of electrostatic resistant polythene mining tube mother material, test detection factually and in polyethylene, add the resistance that metallic particles can make electrostatic resistant polythene mining tube mother material and be reduced to below 50 Ω, far below the existing resistance that is added with the electrostatic resistant polythene mining tube mother material of antistatic material.The amount that metallic particles adds is 5～20, can guarantee the static resistance of electrostatic resistant polythene mining tube mother material like this, also can be very not big to the toughness of polythene mining tube, intensity and performance impact such as anticorrosive.
Following table is some contrast tables of electrostatic resistant polythene mining tube mother material of the present invention and industry quality index,
| Sequence number | Project | Testing method | Unit | Quality index | Detected result |
