Abstract
The invention provides a manufacturing method of a compound material supporting plate, relating to a supporting plate for mine shafts and solving the problems of complicated technical process, low product strength, short service life and poor safety in the prior art. The manufacturing method comprises the following process steps: fully mixing 40-55% of short glass fiber, 30-45% of resin, 2-3% of mesotherm compound initiator, 1-3% of combined accelerator, 4-8% of defoamer and 5-15% of filling material in mass percentage with a mixer; loading the mixed materials in a die; spotting, and pressurizing and preserving heat; and opening the die, and ejecting out the compound material supporting plate. The compound material supporting plate is suitable for mine shaft and tunnel supporting, is simple to manufacture and has the advantages of high product strength, safe support and the like.
Description
Technical field
The present invention relates to mine working supporting supporting plate, particularly a kind of protective support plate of matrix material.
Background technology
The mine working protective support plate is the equipment that uses as roadway support during mining mineral resource under the mine.At present supporting carrier for mining mainly contains wooden and two kinds on metal, and perishable in the wet environment of down-hole although wooden protective support plate is lightweight, work-ing life is short, and it is many to consume timber; Although Steel Lining supporting plate intensity is high, shortcoming is: (1) is easily corrosion under the wet condition of tunnel, and the supporting plate intensity after getting rusty descends rapidly; (2) weight is large, and the underground labour carries relatively difficulty of construction, and labour intensity is large; (3) produce easily spark with the metal tools collision, easily cause the local gas blast, have potential safety hazard.
Along with the development of matrix material industry, increasing mining product is replaced by composite products.At present, composite-material protective support plate is applied in the colliery, and its production method has two kinds: a kind of is to add the multiple glazing fiber in resol, is shaped in pressing mold.Although this method product strength is higher, manufacturing process is complicated, and cost is high, is easy to occur delamination in the use, affects work-ing life and the safety of product, and in addition, tailing is more in the production.Another kind is to adopt the plastic pad moulding, although this method technique is simple, with low cost, not only product strength is lower, and easy quick-fried lid when using, and is dangerous.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, a kind of manufacture method of composite-material protective support plate is provided, solve the existing method that adds the multiple glazing fiberizing in the resol that adopts, manufacturing process is complicated, cost is high; Adopt the method for plastic pad moulding, product strength is low, the life-span is short, unsafe problem.
Task of the present invention is achieved through the following technical solutions:
A kind of manufacture method of composite-material protective support plate is characterized in that: the step of described method is:
(1) with mass percent is 40～55% short glass fiber, is equipped with 30～45% resin, 2～3% middle temperature composite initiator, 1～3% combination promotor, 4～8% defoamer, 5～15% filler, fully stir with stirrer;
(2) material that stirs is packed into pressing mold;
(3) matched moulds, pressure heat-preserving, pressure 10～30MPa, 80～120 ℃ of temperature, 1～3 minute dwell time;
(4) die sinking ejects composite-material protective support plate.
Described resin is for being fit to the unsaturated polyester resin of mould pressing process; Described short glass fiber is the woven glass roving fabric of alkali-free or middle alkali; Described middle temperature composite initiator is benzoyl peroxide; Described combination promotor is dibenzoyl peroxide-tertiary amine; Described defoamer is the BYK-A555 defoamer; Described filler is calcium hydroxide.
The present invention compared with prior art has the following advantages and beneficial effect:
Because the present invention has adopted a kind of galss fiber reinforced resin based composites mold pressing to make protective support plate, therefore, it is simple that the present invention has manufacture craft, high, safe and reliable, fire-retardant, the antistatic and low cost and other advantages of product strength,
