Description
Technical field
The present invention relates to thermoplastic resin technical field, especially relate to a kind of manufacturing installation and method that strengthens thermoplastic resin.
Background technology
Thermoplastic resin is the resin being widely used in a kind of modern industry manufacture.Wherein fiber-like strengthens thermoplastic resin owing to having the characteristics such as higher mechanical strength, heat resistance than original general resin, so its performance is more superior compared with primary resin, application is more extensive.
The fiber that strengthens modification for resin includes: have glass fibre, carbon fiber, metallic fiber, metal-oxide fiber (as ZnOw, alumina whisker), alumina silicate fibre, potassium titanate crystal whisker, silicon carbide fibre, asbestos fibre, gypsum fiber, boron fibre etc.For the ease of fibrous material is added in resin, in manufacturing modified resin process, generally need to carry out surface treatment to fiber, thus as added coupling agent in fibrous material so that fiber be combined better with resin, in fibrous material, add collecting agent so that the state of fibrous material formation multifilament boundling is more easily carried fibrous material.But interpolation kind and the addition of collecting agent and coupling agent have great impact to composite modified resin performance.Therefore, in existing composite modified resin preparation technology in order to guarantee that the performance of composite modified resin can strict kind and the addition of controlling coupling agent, collecting agent.
Generally, if will guarantee modified resin product quality, the feed rate precision of fibrous material be preferably controlled at target flow ± 2% in, feed rate precision be controlled at target flow ± 1% with interior, can produce more high-quality modified resin product.
In the preparation process of composite modified resin of the prior art, first the conveyer by is separately transported to fibrous material and thermoplastic resin in plastic extruder, then by plastic extruder by fibrous material and thermoplastic resin, be then extruded as composite modified resin.Wherein, the conveyer of fibrous material is generally screw, belt-type and oscillator.Wherein kind and the addition due to collecting agent is subject to strict restriction, to fibrous material in the process of the continuous conveying fiber material of extruder, easily there is separating fine problem in conveyer, glass fibre and carbon fiber performance clearly, are wherein more prone to occur separating fine problem with carbon fiber boundling body especially in course of conveying.In course of conveying, fibrous material easily departs from the constraint of collecting agent, by larger boundling body, be decomposed into less boundling body, even be decomposed into independently fiber individuality, and the fibrous material boundling body of small size and independently fibrous material are individual because weight is extremely light, in transfer passage, easily disperse, yet vias inner walls be rolled into a ball and be attached to staple in bulk can along with increasing of quantity is gathered into batting gradually in transfer passage, therefore in successive conveying fiber materials process, having little batting agglomerate is scattered at random and enters extruder, and then the instantaneous phenomenon increasing of generation fibrous material concentration, cause proportion of fibrous material to raise, formula for a product proportional error is increased, affect the charging precision of fibrous material, finally cause deterioration in quality.Large batting shape agglomerate can cause the obstruction of passage, and then the supply flow rate that has influence on fibrous material even causes the complete shutoff of transfer passage and cannot charging.When batting shape agglomerate greatly to a certain extent; at certain, come off suddenly and enter in extruder in a flash; cause the raw-material proportioning gross error of composite modified resin even make extruder damage and shut down ，Gei manufacturer and bring huge product quality accident and equipment loss.
