Abstract
The disclosed pipe uses polyvinyl-chloride as raw material and anti-static agent, fire-retardant agent, stabilizer, lubricant, and coupling agent etc. as additives and is made up through the processes of kneading and extruding. The technological process is as follows: compounding raw materials according to th recipe-Kneading-extruding-sizing-cooling-pulling-cutting-product. The pipe made by said method features corrosion resistant, fire-retardant, antistatic, low cost, high mechanical strength and being an ideal polyvinyl pipe for mine shaft water-draining and exhaust blowing.
Description
The present invention relates to a kind ofly have the manufacture method of anti-electrostatic fire retardant performance plastic pipe as base-material, be applicable to mining industry drainage underground, air draft with polyvinyl chloride.
At present, the tubing that mining industry drainage underground, air draft are used mainly is steel pipe, but it exists cost higher, and the inconvenient shortcoming of transposing is installed.By national patent on-line network is retrieved, the patent No. " 92243657.6 " utility model patent is disclosed to be anti-electric static flame retardant glass fiber reinforced plastic plastic composite pipe, advantages such as it is antistatic, fire-retardant, corrosion-resistant that though it also has, but there is the high shortcoming of cost in it, can not be widely used in mining industry drainage underground, air draft use.
The purpose of this invention is to provide that a kind of cost is low, that transposing is installed is convenient, have the polyvinyl chloride plastic tubing and the manufacture method thereof of advantage such as antistatic, fire-retardant, corrosion-resistant simultaneously.
The present invention is achieved through the following technical measures, the raw material of polyvinyl chloride tubing by: PVC, antistatic additive, fire retardant, coupling agent, CPE, ACR, three salt, calcium stearate, stearic acid, lubricant etc. are formed, various proportion of raw materials are: 26-32 parts in PVC:100 part, antistatic additive, 5 parts of fire retardants, 0.03 part of titanate coupling agent, CPE8 part, ACR5 part, 3 parts of lead sulfate tribasics, 2 parts of calcium stearates, 1.5 parts of barium stearates, 2 parts of stearic acid, 2 parts of lubricants, its technological process is as scheming:
Because the present invention makes base-material with polyvinyl chloride, added compositions such as acetylene carbon black, fire retardant again, so both kept original advantage such as acidproof, alkaline-resisting, corrosion-resistant, have antistatic and fire-retardant performance simultaneously again; Technological process of the present invention is simple, and technical do not have an excessive demand, is easy to grasp and implement; In addition, use product of the present invention, its construction costs is lower than the steel pipe of identical quantities, so can be widely used in the down-hole, mine.
With an embodiment the present invention is described in detail below.
The manufacture method of polyvinyl chloride antistatic pipes, at first with the combination by weight of various raw materials, make base-material with polyvinyl chloride, get 100 parts, antistatic additive 26-32 part that acetylene carbon black is composited and by containing the fontanel organic matter, 0.03 part of the coupling agent that 5 parts of fire retardants that antimony oxide is composited are made raw material in order to metatitanic acid fat carries out the surface to give and removes reason, make its surface active, get CPE8 part again, ACR5 part, 3 parts of lead sulfate tribasics, 2 parts of calcium stearates, 1.5 parts of barium stearates, 2 parts of stearic acid, lubricant is added in the kneader as other auxiliary agent with various raw materials for 2 parts successively, the low speed cycling start, mediate at a high speed, mediate temperature and be controlled between 105 °-110 ℃, can discharging cool off, after extruder is extruded, through the vacuum sizing moulding, after spray cooling but, the cutting machine cutting detects warehouse-in.The sheet resistance of mining polyvinyl chloride antistatic pipes can be controlled in the specified standard MT181-88 of Ministry of Coal Industry, less than 10 ohm, fire-retardant index is pressed the CB2406-88 method and is measured, oxygen index (OI) is greater than 27, softening temperature 〉=79 ℃, decomposition temperature 〉=190 ℃, hot strength 〉=35.4mpa ， Luo Chung impacts and does not break.
