Description
Technical field
The utility model relates to a kind of shaped device of shape product of continuous glass-fiber reinforced hard polyurethane microfoam.Belong to polyurethane microvesicle former technical field.
Background technology
Polyurethane foam plastics is one of principal item of polyurethane synthetic material.It is mainly made by organic isocyanate and polyol compound reaction.The variation of different according to used raw material from prescription can be made kinds such as soft, semi-rigid and rigid foam.The rigid foam aspect: density is less is mainly used in insulation material, as the insulation of refrigerator, water heater and pipeline; The high density polyurethane rigid foam also is described hard polyaminoester microvesicle, has natural timber and can saw to dig and performance such as can follow closely, and can be used for making imitative wooden handicraft and decoration, as picture frame, picture frame and automotive upholstery etc.Advantages such as the RPUF relative density is little, good heat insulating, moulding are easy are that people are known, but this plastics and other materials such as hardwood, fiberglass compares, and it is more that intensity difference gets, and limited its range of application.If fiber glass reinforcement is joined in the RPUF matrix, its intensity can improve 3～4 times.In addition, the effect that then strengthens of the length difference of glass fibre also has evident difference.The enhancing of chopped strand has some application, can be used as some aggregated(particle) structure spares, as parts such as the ceiling interior trim of the luggage carrier of motor bus, dolly, building wall boards.It is contemplated that, if strengthen the hard polyaminoester microvesicle with continuous glass fiber yarn, the goods that resulting goods strengthen than chopped strand, its mechanical performance especially hot strength, bending strength has by a relatively large margin raising.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of coextrusion mold device of shape product of continuous glass-fiber reinforced hard polyurethane microfoam is provided.
The purpose of this utility model is achieved in that a kind of shaped device of shape product of continuous glass-fiber reinforced hard polyurethane microfoam, it is characterized in that it comprises mould, guide plate II, glass yarn carding machine, guide plate I, drying tunnel, raw material storage tank I, raw material storage tank II, high pressure foaming machine, synchronizing tractor and cutter sweep
Described mould from A-P include common notes chamber successively, heat foamed solidification district and cooling and shaping district form.Guide plate II is arranged at front side, common notes chamber, and glass yarn carding machine places the place ahead, common notes chamber, and guide plate I places glass yarn carding machine the place ahead, and drying tunnel places guide plate I the place ahead,
Described raw material storage tank I, raw material storage tank II and high pressure foaming machine place the top, common notes chamber or the side of mould, and raw material storage tank I links to each other with high pressure foaming machine with measuring pump II by measuring pump I respectively with raw material storage tank II,
Described synchronizing tractor places the rear, cooling and shaping district of mould, and cutter sweep places the synchronizing tractor rear.
Its coextrusion forming process is as follows:
1), modified isocyanate and add respectively in two material storaging tanks by the good combined polyether of formulation, and two material storaging tanks are adopted the water-bath heating,
2), the continuous glass-fiber yarn earlier removes surperficial adsorption moisture through drying tunnel, undertaken making it to be the monofilament shape after combing disperses by carding machine again and evenly distribute,
3), the glass yarn after disperseing under the traction of draw-gear is promptly annotated chamber, foamable consolidation zone and cooling and shaping zone altogether by the impregnation chamber of mould continuously, the polyurethane stock solution that the two components of while combined polyether and modified isocyanate obtain after high pressure foaming machine mixes is annotated the chamber altogether at mould sprue soaks into the glass yarn equably by the automatic motion scan device of mechanical hand-guided, make discharging, impregnation keep uniform state
4), the common injection body of glass yarn and polyurethane stock solution foamable consolidation zone and the cooling and shaping zone by mould successively, thereby make common injection body foamed solidification typing obtain continuous shape product,
5), employing is infrared carries out the cutting of fixed length from the long cutting machine of motion tracking survey to shape product.
The utility model carries out being the monofilament shape after combing makes it to disperse by the glass fibre carding machine to the glass yarn and evenly distributes, with adequacy and the uniformity that guarantees that polyurethane stock solution soaks into, and before combing, the adsorption moisture on yarn surface is dried in order to avoid influence foamed solidification reaction and interface combination.
The stoste that the utility model obtains after by special equipment and device the polyurethane bicomponent material being stirred is soaked into continuously through combing and is disperseed the dry continuous glass-fiber yarn of crossing, and the method for employing coextrusion mold makes the production of goods can serialization.
