Abstract

A process for finishing armoured resin products or thermoplastic resin products is characterized by applying on the surface of the resin product A at least one layer or sheet D of suitable heated thermoplastic material; applying to said layer D a pneumatic pressure to cause this to adhere integrally and evenly to the surface of the product; and cooling the whole so that, in contracting, said layer penetrates and secures itself firmly to the surface of the product. The process is particularly suitable for finishing protective helmets. <IMAGE>

Description

SPECIFICATION Finishing process for armoured resin products This invention relates to a process for finishing armoured resin products, for example helmets and similar products; the invention also relates to the products obtained by this process.
The armoured resin products include in particular protective helmets, where the invention is most advantageously but not exclusively applied. Helmet structures generally have surfaces (especially visible surfaces) which do not quite satisfactorily meet the end use requirements of the product. In particular, the surfaces of certain armoured (i.e. reinforced) resin products are rough and irregular, due princi pallyto points, projections or other irregularities consisting of the armour threads embedded in the resin. Moreover, the surfaces of certain other products, even if smooth, are of repellent nature and hence are not adequate to ensure integral and long lasting adhesion of lining or colouring layers, applied to obtain aesthetic, but mainly protective effects.
An object of the invention is to obviate these drawbacks and limitations making it possible to eliminate finishing, preparation smoothing and other operations which were hitherto necessary to make the resin products suitable for the end use to which they are destined. For example, in the case of protective helmets for sports and similar uses, it is possible to eliminate the operations intended to obtain a lower surface adapted to retain both the coloured layer and/or decorations and the protective transparent layer.
A further object of the invention is to provide products with smooth surfaces and having satisfactory aesthetic appearance, the surfaces being also adapted to reproduce decorations and/or symbols.
A A still further object of the invention is to provide a complete and satisfactory protection of the resin product structures, especially armoured structures, which generally afford a certain resistance to atmospheric agents, thereby avoiding damage of the products by the action of such atmospheric agents.
The present invention thus provides a process for finishing armoured resin products, which comprises applying to at least part of the resin product surface at least a layer or sheet of pre-heated thermoplastic material, applying to the plastic layer or sheet a differential pneumatic pressure to cause it to adhere integrally and evenly to the surface of the product, and cooling the whole so that the layer or sheet, in contracting, penetrates into and anchors itself secsurely to the surface of the product.
In order to obtain a practically indisoluble coupling between the thermoplastic layer and the surface of the product, the surface is preferably pre-treated with a stratum of a suitably polymerizable resin such as thermo-polymerizable resin, for example, butadiene, epoxy, acrylic and urea melamine resins.
Obviously, the colouring layer and/or designs on the surface of the product are reproduced in advance on the surface of same, or on the lower face of the plastic sheet, so that they will be thus interposed between the product surface and the plastic sheet, and thus protected.
The plastic sheet or layer can be conveniently applied to the product by placing the latter in a vacuum chamber closed in part by said layer or sheet, so that after being heated and made plastic, the sheet is caused to adhere, by the action of atmospheric pressure, to the desired surface of the product. In the specific case of armoured resin protective helmets (in which the invention is most advantageously but not exclusively applied) plastic lining and protective sheets are applied, the characteristics of these sheets preferably being such that the modulus of elasticity of the resin forming the sheets differs from that of the bonding resins used to produce the armoured structure of the helmets.This is in order to reveal to the user of the helmet (or other armoured resin product) any deformations and/or damages to the armoured resin structure resulting from shock, impact, blows etc. undergone by the helmet (or similar product) and which may limit or jeopardise in any way the protective efficiency of the structure. This is because in the zone of the armoured resin structure (provided with the protective sheet having the elasticity characteristics just considered) which has been subjected to shock or impact, the protective sheet detaches itself from the structure's surface. Such an irregularity, although not perceptible visually, can be detected acoustically by lightly tapping on the helmet surface, thereby permitting localization of the damaged area in the structure.
Reference is now made to the accompanying drawings, in which: Figure 1 shows schematically a preferred embodiment of apparatus used to carry out the process according to the invention; Figure 2 is a view similar to Figure 1 of a variant of the embodiment of the apparatus used according to the invention; Figure 3 is a cross-sectional view, on a layer scale, showing the structure of the layers of a product obtained with the process according to the invention; and Figure 4 is a view similar to Figure 3 of a variant, in cross section, of the structure.
With reference to the drawings, there will now be described, by way of example, a preferred process according to the invention for finishing a protective helmet for sports use. Such helmets usually consist of a resin structure incorporating a suitable reinforcing armour, for example, textile or glass fibres etc. In other patents by the same author the armour of the helmet is made of textile material.
The helmet A in Figure 1, fabricated in the usual way, that is, by moulding, after being removed from the mould is placed on a support B slidably mounted in a pneumatic chamber C provided with a fitting Ca to connect the inside of said chamber with an air This print takes account of replacement documents later filed to enable the application to comply with the formal requirements of the Patents Rules 1978.
vacuum source.
For a satisfactory achievment of the object of the invention, the outer surface of the helmet A is pretreated with a layer of suitable adhesive cement material of the polymerizable and/or thermo hardening type such as acetovinyl, acetophenol, chloroprene, resorcinic and, in particular, thermopolymerizable materials such as epoxy and acrylic resins which improve adhesion and colour. The application of the adhesive layer is extended and increased in the area of edges A, of the helmet or similar product, for the purposes explained below.
The opening in the pneumatic chamber C is closed tightly by a flexible sheet lamina D of thermoplastic material, adapted to meet heat moulding requirements. In particular, sheets of polypropylene, polystyrene, acryl, polyvinyl, or polyacetate resins are used in a thickness of from 0.05 to 2,0 mm. These sheets can be conveniently coloured depending on end use or other requirements; advantageously, and to account for specific applications, the sheets are transparent, especially if they are to permit designs or decorations on the helmet surface to be seen. In such cases, the flexible sheet D is pre-printed and/or coloured with the usual known procedures, in such manner that the image reproduction is applied on the rear face of the sheet and is visible through the transparent sheet.The protected sheet D, thus prepared, is then placed in the opening of the pneumatic chamber C and secured at its edges with a frame C2 which, in addition to anchoring the sheet to the chamber, provides a tight seal on the latter. The pneumatic chamber C is then connected with a suitable heat source, for example infrared rays, to impart to the sheet D the desired plasticity.
The helmet A is prepared in advance to receive the lining sheet D and, if required, it can be provided with an adhesive layer F of the type already considered, for example, an epoxy base adhesive. The helmet is then placed on the supporting platform B and housed within the pneumatic chamber C which is then tightly sealed by the sheet D.
The latter is subsequently heated and when it has reached the desired degree of plasticity, a vacuum is created in the chamber C; at the same time, the platform B is lifted so that the sheet adheres and becomes anchored to the profile of the helmet A to form thereby the lining and protective surface for the helmet A. It ensures that any irregularities on the helmet are incorporated into the plastic body of the sheet D thereby to obtain a smooth surface which does not require anyfurtherfinishing work.
Moreover, any design or symbols on the bottom face of the sheet D will be reproduced and located in the desired position on the helmet and protected in particularfrom atmospheric agents.
According to the invention and with reference to Figure 2, a variant of the process will now be described. In Figure 2 parts equal to those of Figure 1 are identified with the same reference symbols.
In order to facilitate and ensure adhesion to the surface of the product A (especialiy if this has a certain height) the sheet D is suitably preformed in the shape of a cap D1, within which the helmet A can be freely and conveniently inserted.
The edge of the cap D is then securely anchored between the frame C2 of the pneumatic chamber C and, after heating the cap and introducing the hel met A into it, a vacuum is created in the chamber C to impart to the surface of the cap differential pres sure which in turn cause said cap D to adhere to the surface of said helmet. An adherent lining of constant thickness is thereby produced since the tension exerted on the cap is limited, even when the helmet A is of considerable height. Obviously, in relation to dimensional characteristics and shape of the product A to be lined with the thermoplastic sheet D, the most suitable heat forming procedure may be selected and adopted, for example, the combined action of vacuum-compression orthe use of counter dies to engage said sheet with the surface of the product A.
According to the invention, before complete cooling of the sheet D, the lined helmet A is removed from the platform B and the free ends D, (see Figures 3 and 4) of the sheet are trimmed, folded over and caused to adhere to the internal perimeter zone of the helmet. This operation can be performed also with the aid of adhesives F to ensure indissoluble bonding of the sheet to the helmet surface.
In addition, for the purpose of obtaining full adherence between the contact surfaces of the product A and the sheet D, in particular when the product surface dimensions are large, while the internal structure is compact (as in helmets), small through holes or apertures A2 are provided in the product structure (Figure 4). In this case differential pressures are created on both faces of the sheet D, in that the helmet cavity is transmitted to the exterior and hence the sheet D is subjected immediately and evenly to atmospheric pressure or, generally, to a pressure greater than that prevailing in the cavity of the helmet. Continuity of the bond between the sheet and helmet surface is thus ensured.The presence of any adhesive between the surface of the helmet A and the sheet D will not affect the drawing action exerted on said sheet because said adhesive layer F is constantly in the fluid state during the operation, and also influenced by the thermal action on said sheet D. Moreover, it is possible to close the holes A2 in the helmet A by causing the adhesive in the fluid state to be suctioned, at least in part, during the vacuum formation, and in drying the adhesive becomes integrated with the helmet structure.
Instead of providing holes A2 in the structure of the helmet A, the structure may, at least in part, be treated with a pore forming agent adapted to create in the structure small cavities or open cells. Moreover, the securing of the ends D, to the structure of helmet A can also be effected by mechanical means such as stitches, sewing etc.
The process described above produces armoured resin products with finished and smooth surfaces, without the need for lengthy and complex operations. Moreover, in the specific case of helmets, in addition to the advantages just considered, it becomes possible to verify, at any time, the integrity of the armoured resin structure in relation to any shock or impact to which it may be subjected. In fact, in the case of shock and because of the different elasticity moduli of the armoured structure and sheet D, a discontinuity of the lamellar union zone is generated in the area of adhesion.
Such an anomalous condition is revealed and perceptible by lightly tapping on the helmet, even when the helmet which has been subjected to the shock does not show any sign of damage.
