Abstract
A kind of mine with individual prop with fire-retardant, anti-static composite material post footwear, it is to be coated with to have scraped the anti-electrostatic fire retardant unsaturated polyester resin on the compound glass fiber, the centre is embedded into compression molding behind the steel plate, or on steel ring, twine a certain amount of anti-electrostatic fire retardant unsaturated polyester resin, the mould inner pressure system of putting into then forms.Its configuration design has reinforcing rib, centring ring, bottom to have anti-skidding muscle, product technology is simple, steady quality, in light weight, price is low, corrosion-resistant, intensity is high, be the splendid renewal product that individual prop is used under the mine.
Description
The present invention relates to a kind of underground mine use individual prop post footwear, especially a kind of antistatic, the post footwear of flame-proof composite material.
At present, glass fibre reinforced plastic prop shoe, nylon column footwear and cast steel post footwear etc. have successively appearred in the individual prop of China's coal-mine down-hole use.(seeing the patent No. 88200818.8 and 88202603.3) appearance of these post footwear has improved the sinkage of pillar greatly, the degree of depth of sinking is improved as less than 10cm by 60 original～100cm, through underground work experiment setting load, average working resistance can reach 9.6T and 15.5T, maximum can reach 30T, thereby preferably resolve the sinking problem of coal mine lower supporting rod, but also exist many weak points.
Require according to People's Republic of China's coal industry ministerial standard: MT113-85 " underground mine use nonmetal (polymer) goods security performance inspection specification ":
" each coal company, mineral bureau colliery and coal machine factory must not adopt without authorization without Ministry of Coal Industry and specify the qualified non-fire-retardant on-metallic article of underground mine use of checklist bit trial." according to this regulation, phenolic fiberglass reinforced plastics post footwear and nylon column footwear all do not possess fire-retardant, anlistatig instructions for use, the about 35 yuan/piece of the every block cost of nylon column footwear is on the high side, not susceptible to user acceptance in addition.Cast steel post footwear, although possess advantage fire-retardant, antistatic and that intensity is high, these post footwear are too heavy, every about 8Kg also is difficult for large-scale promotion and popularizes.Though a kind of bamboo matter post footwear occurred at present, these post footwear and wooden post footwear are similar, light weight intensity is little, and pressure that only can the about 5T of load-bearing can not be used basically.
For above problem, also there is not good solution now.
The objective of the invention is to provide a kind of is main adhesive material post footwear with unsaturated polyester resin, and it is not only cheap, and in light weight, and anti-electrostatic fire retardant is good, and intensity might as well.Possessed the service condition under the coal mine.
The present invention is achieved in that to adopt to have the flame-retardant and anti-static resin as main adhesive material, in add glass fiber, steel as framework material, mold pressing is made at ambient temperature.In the configuration design, design has reinforcing rib, centring ring, increases anti-skidding muscle at the post sole part.
Owing to adopt above scheme, these post footwear are fire-retardant, antistatic to have reached MT113-85 " standard " requirement; The intensity height, hollow load compressive strength reaches 500KN, and compressive strength reaches 25KN/cm
2, (about 3Kg) is corrosion-resistant for price low (about 18 yuan /) light weight.Compression molding steady quality at normal temperatures, technology is simple, easily grasps, and energy consumption is low, and the production efficiency height is pollution-free.
The present invention is further illustrated below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1, footwear body, 2, centring ring, 3, reinforcing rib, 4, steel plate or steel ring, 5, anti-skidding muscle, 6, antistatic, flame-proof composite material.
Embodiment 1: the post footwear are on the glass fiber of φ 260～φ 300mm, be coated with and scrape the saturated polyester resin antistatic, that anti-flammability is strong, add to 10～30 layers approximately, put into φ 180～φ 220mm, the steel plate of thick 4～6mm, stick again and be coated with 10～30 layers of glass fiber scraping unsaturated polyester resin, put into mould then, in the mould table nest, scribble unsaturated polyester resin in advance, closely connected glass fiber, wait to close after the template, 5～50Kg/cm exerts pressure
2Pressure, solidify the back depanning, treat its more fully spontaneous curing can use.
Embodiment 2: coat antistatic, flame-retarded unsaturated polyester resin, closely connected glass fiber in the mould table nest.Then, twine on the steel ring of φ 250～φ 290mm and flooded glass fiber antistatic, flame-retarded unsaturated polyester resin, treat to put into mould when thickness reaches 15～30mm, matched moulds applies 5～50kg/cm
2Pressure, solidify the back depanning, can use after the spontaneous curing fully.
Among the figure, footwear body (1), centring ring (2), reinforcing rib (3), anti-skidding muscle (5) is compression molding, and steel plate or steel ring (4) are inlet part in advance.
Claims (2)
1, the post footwear that individual prop uses under a kind of coal mine, by phenolic glass fiber, nylon plastic(s) and cast iron are made by mold pressing injection moulding and cast respectively, it is characterized in that: footwear body (1), centring ring (2), reinforcing rib (3), anti-skidding muscle (5) be by being coated with the glass fiber garden sheet of scraping unsaturated polyester resin, in be embedded into steel plate or steel ring (4) back compression molding.
2, mining antistatic, flame-proof composite material post footwear according to claim 1, it is characterized in that: on the steel ring of φ 250～φ 290mm, twine and flooded glass fiber antistatic, flame-retarded unsaturated polyester resin, put into mould behind thickness 15～30mm, apply 5～50kg/cm
2The pressure-cure depanning after, treat that complete spontaneous curing can use.
