Description
The invention belongs to the fiber hybrid composite production technical field, particularly bamboo fiber bar (bamboo strip or bamboo chip or the like) and glass fibre etc. are cooperated to strengthen the thermosetting resin pultrusion and make various prismatic linear bamboo bar Glass Steel Tubes and forming method.
At present, known fibre glass roving pultrusion plumber skill is a kind of method of continuous producd fibers reinforced plastic section bar.It is the non-twist fibre glass roving on the creel to be carried out resin with other continuous reinforcing material, surface of polyester felt etc. soak achievement, then by keeping shaper, the shaping die of definite shape, and make it after the moulding of mould internal heating curing, be pulled continuous depanning, through cutting off a kind of automatic production process that can obtain glass fibre reinforced plastics pultrusion pipe.Various glass fibre reinforced plastics pultrusion pipe product performance are good, have wide range of applications, but cost are too high, and the application scale is not very big.The bamboo wood compact structure, resistance to compression, tension, wear-resisting property is good, malleable is good, and the specific humidity rate that rises is little mutually with other vegetable fibers such as timber, and its corrosion resistance more is better than other vegetable fibers such as timber.Bamboo wood growth rapidly, renewable is strong, compares cheaply with other lamination coating, produces the usage requirement that various drawing and extruding section bar products can satisfy many occasions with good bamboo material.But little owing to bamboo bar hollow, diameter, become plate poor performance, limited length and isolating property greatly, easily to go mouldy, compare with plastics or glass fibre reinforced plastics series products under the nature weather resistance poor, directly and the multiple reason of the compound compatibility performance difference of various fluoropolymer resins or the like, it can not be used on the pultrusion product, and therefore a large amount of bamboo materials fails to bring into play its due effect.Big, the easy-to-rust of weight such as steel pipe, cast iron tube, cement pipe is installed inconvenience now; Plastic tube intensity is low; Glass Steel Tube price height.
In order to overcome the deficiency of short and small or the like the shortcoming of the high and bamboo material of existing glass fibre reinforced plastics pultrusion product price, bamboo-glass fiber pulled and extruded bamboo splint-glass fiber reinforced plastic pipe product provided by the invention, this bamboo bar Glass Steel Tube product can not only guarantee to make full use of that the bamboo material contour projector is little, elasticity and toughness is all high, tensile strength parallel to grain is about 1800kg/cm
2, parallel-to-grain compressive strength is about 800kg/cm
2Or the like proper property, and have the outward appearance and a performance of glass fibre reinforced plastic material, permeability with glass fibre reinforced plastics under the situation about needing also can make it to have the outward appearance that manifests bamboo material, utilize the coating skin of glass fibre reinforced plastic material to intercept bamboo material and air simultaneously, unfavorable and hostile environments such as mould, the contact of material, therefore can be under the prerequisite of the original performance that guarantees bamboo material, prolonged working life widely, also be easy to simultaneously by increasing, the content that reduces glass fibre improves, reduce glass fibre reinforced plastics content and control the performance and the price of bamboo bar fibre glass product manufacture, can satisfy the usage requirement of many applications, also be better than glass fibre reinforced plastics as heat-shielding performance etc., the particularly reduction of price can realize large-scale promotion application.
The technical solution adopted for the present invention to solve the technical problems is: the bamboo fiber bar that at first bamboo processing is become all size that needs by design, in advance same specification cross section have limit for length's bamboo fiber bar through butt joint, finger, play splicing such as groove overlap joint, lining felt, lining paper, lining cloth or mechanical coupling becomes the continuous bamboo fiber bar of endless, be called for short continuous bamboo bar, the bamboo bar is wound into volume continuously, is called for short the bamboo silver lap.Next the bamboo that as required the bamboo silver lap of multireel same size or different size is placed on the fiber frame is rolled up on the frame, corresponding with every bamboo bar as required a volume or multireel woven glass roving fabric be placed on the fiber frame with the corresponding creel of this bamboo bar on, other roving volume, glass fiber mat, glasscloth or the like other reinforcing material is placed on the fiber frame on corresponding yarn, felt, the fabric frame, draw various reinforcing fibers such as bamboo bar, rove, felt, fabric by organiser, as required by the dehumidifying of dehumidifying heater, heating.Enter steeping vat preimpregnation achievement resin, the reinforcing material that preimpregnation is good (bamboo bar, rove, felt, fabric or the like) passes metal pre-setting device, mould or the device and mould pre-setting of shape with the approaching belt carcass mould of section bar sectional shape, it is filled glass fiber yarn around the slit of yarn bamboo bar and has been formed the multi-cavity chamber wall that cavity flow line style chamber arm separates the engine blade cavity by the coating of glasscloth, felt etc., make bamboo bar, rove, fabric, felt etc. accurately in conjunction with, remove the bubble in unnecessary resin, the eliminating system.Then enter the continuous bamboo bar glass fibre reinforced plastics pultrusion product that the forming and hardening mold heated with multistage heating function is solidified into required sectional shape, this product deflects from mould under the traction of traction gear, after the cutting device fixed length cutting becomes the pulled and extruded bamboo splint-glass fiber reinforced plastic pipe product of Len req.Pultruded bamboo fiber reinforce plastic wrapped pipe product can be that the solid wall pipe section bar also can be the pipe profile of interlayer wall.
The invention has the beneficial effects as follows, the various pulled and extruded bamboo splint-glass fiber reinforced plastic pipe products that go out by this processes can enlarge the application area and the application of bamboo material widely, can guarantee that bamboo material given play to huge usefulness, by the slit of glass fiber yarn filling bamboo bar and by glasscloth, the coating of felt etc. has formed the stomach wall of profile shapes on an empty stomach, this has reduced isolating property, simultaneously also increased compatibility with fluoropolymer resin by glass fiber yarn, realize can leaning between the bamboo bar mechanical connection of glass fiber yarn and resin, this has eliminated bamboo bar and the compound segregative disadvantage of polymeric matrix.Can determine or not non-twist glass fiber yarn, felt, fabric to wait around single bamboo bar, many bamboo bars, whole bamboo bar and fibers according to usage requirement rotates, what are around amount, can require to design the bamboo bar glass fibre reinforced plastics pultrusion product of various structural styles and bamboo glass ratio according to usability around the few good product performance of amount big bamboo bar surface exposure amount, and improve bamboo glass ratio as far as possible to reduce the demand that cost satisfies large-scale application.Bamboo-glass fiber pultrusion material is compared with bamboo glass fabric pultrusion product to have reduced and is weaved link and shortened technological process, therefore has the low advantage of cost.
The present invention is further described below in conjunction with drawings and Examples.
