Abstract
The present invention discloses a composite material mine top net. It is made up by using core shaft and strip material whose surface is formed from anti-static layer through a mutually-crossed weaving process. The described core shaft is formed from glass fibre bundle and resin, solidifying agent, accelerator and flame resisting agent, and the described anti-static layer is composed of resin, solidifying agent, accelerator, anti-static agent and flame-resisting agent.
Description
Technical field
The present invention relates to the mine protector, specifically, is a kind of roof net.
Background technology
Roof net is when being used under the coal mine high seam and super high seam separate zone production, does that top is protected on artificial false top, breaking roof part, single coal seam, work plane finishes up and the facility of usefulness such as roadway support.During use, utilize the tunnel support anchor rod that the top net is fastened on the tunnel crag.That uses at present mostly is the metal roof net, and its intensity is higher, can satisfy common instructions for use, but has a series of shortcomings: 1. because complicated geology has the water source more, wire lath is met the water easy-to-rust, easily causes the run-down cash of lower leaf net, influences Coal Quality; 2. wire lath weight is big, and workman's manipulation strength is big, and the production operation environment is poor; 3. the mine timber consumption is big; Workloads such as 4. invalid transportation, washing and expense are too high; 5. meet the powder granule impaction phenomenons such as gas explosion easily take place.
Along with nonmetal industrial expansion, increasing wire lath is replaced by nonmetal net, and has obtained very big economic benefit, and the separate zone production of wherein using mining plastic wire alternative metals net to be used for the colliery high seam is exactly an example of giving prominence to.This technology has obtained applying in the whole nation after occurring the nineties in 20th century soon.Because of its use cost is 1/3 of steel only, and have corrosion resistant advantage in light weight, be subjected to the welcome of coal mine user.Because the rise of plastics price, its advantage on price has not had but in recent years.On the other hand, plastic wire intensity is little, hardness is low, poor rigidity, has limited the application of plastic wire.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of composite material roof net and manufacture method thereof are provided, solve existing metal roof net cost height, deal is heavy, workman's manipulation strength is big, corrosion-resistant, can not antistatic, meet collision of irony instrument or powder granule impaction problems such as gas explosion easily take place, overcome that plastic wire intensity is little, hardness is low, the shortcoming of poor rigidity.The present invention has safety, reliable, fire prevention, antistatic and low cost and other advantages, and wide application prospect is arranged.
To achieve these goals, the present invention has taked following technical scheme:
A kind of composite material roof net, form by cross one another warp and parallel braiding, described warp, parallel are a kind of billots made from composite material, the structure of billot is made of mandrel and surface anti-static layer, mandrel is made up of glass fiber bundle and resin, curing compound, accelerator, fire retardant, and its mass percent is: glass fiber bundle 50～57%, resin 35～45%, curing compound 1～2%, accelerator 2～3%, fire retardant 3～6%; Antistatic backing is made up of resin, curing compound, accelerator, antistatic additive, fire retardant, and its mass percent is: resin 75～87%, curing compound 2～4%, accelerator 3～7%, fire retardant 6～12%, antistatic additive 2～6%.
Described resin is adjacent benzene type unsaturated polyester resin, and glass fiber is the alkali-free glass fibre bundle, and curing compound is a methyl ethyl ketone peroxide, and accelerator is different cobalt green styrene solution, and fire retardant is an aluminium hydroxide, and antistatic additive is that antistatic additive SN is produced in Hangzhou.
Described resin can also be metaphenylene unsaturated polyester resin, glass fiber can also be the medium-alkali glass fibre bundle, curing compound can also be cycloethanone peroxide, accelerator can also be cobalt naphthenate solution, fire retardant can also be dimethyl methyl phosphonate, and antistatic additive can also produce antistatic additive for Nanometer Port Co., Ltd., Shenzhen.
The shape of cross section of the composite material billot of described establishment top net is circular, also can be oval, square, rectangle.
The production method of described composite material roof net, its processing step is:
(1) be 50～57% glass fiber bundle with mass percent, be equipped with 35～45% resin, 1～2% curing compound, 2～3% accelerator, 3～6% fire retardant, pass the nib of pultrusion mould, thereby make the cross section mandrel identical with the nib shape;
(2) at mandrel top layer spray antistatic backing, the antistatic backing material prescription is: resin 75～87%, curing compound 2～4%, accelerator 3～7%, fire retardant 6～12%, antistatic additive 2～6%.
(3) billot is cut into predetermined length, adopts the cross one another mode of longitude and latitude that billot is woven into net.
(4) after the top net is woven into, the brushing bonding agent makes that grid is bonding to be integral on the node that all graticules intersect, and the mass percent of institute's coating adhesive material is: resin 75～87%, curing compound 2～4%, accelerator 3～7%, fire retardant 6～12%, antistatic additive 2～6%.
The present invention compared with prior art has the following advantages and beneficial effect:
The present invention is directed at present heavy with mining metal top net cost height, the deal of reinforcing bar welding, workman's manipulation strength is big, corrosion-resistant, meets the powder granule impaction problems such as gas explosion easily take place, and has developed the enhanced type composite material roof net.This product adopts pultrusion+braiding complex technique to process, and has realized the comprehensive utilization of resource, has improved the intensity of product, thereby has strengthened resistance to compression, tension, bending resistance, shock resistance, abrasion resistance and the supporting capacity of product.The application life of have good corrosion resisting property, growing.It is the ideal product that substitutes existing mine working protective screening.
Because the positive and negative at composite material top net all is coated with refractory coating and antistatic material coating, has fire prevention, electrostatic-proof function.Owing to adopt glass fiber material, alternative traditional bamboo wood, reinforcing bar top net have significantly reduced the waste of ecological resources, protect soil erosion and environmental protection simultaneously effectively.The present invention compared with prior art has safety, reliable, fire prevention, antistatic and low cost and other advantages, has broad application prospects.
The present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
