Abstract
The utility model provides a kind of drawing and extruding section bar composite felt, comprise base cloth layer, tack coat and surface of polyester carpet veneer, described base cloth layer is Woven glass cloth layer, tack coat is unsaturated polyester resin powder, take Woven glass cloth as base cloth, sprinkle unsaturated polyester resin powder as tack coat in the one side of Woven glass cloth, in a heated state again at this face compound one deck surface of polyester carpet veneer of the Woven glass cloth sprinkled with tack coat.The advantage of this product is the mode that have employed direct combination, and glass technical fabrics, surface of polyester felt unsaturated polyester resin powder are bonded together, product has very high intensity and globality, and the surface property of product excellence given by surface of polyester felt.This product directly can reduce the operation of pultrude process, for client saves cost of labor.
Description
Technical field
The utility model relates to a kind of composite felt, particularly, relates to a kind of drawing and extruding section bar composite felt.
Background technology
Pultrusion molding process is by the continuous tow of impregnating resin glue, band or fabric etc., under the effect of tractive force, and, solidification shaping by extrusion die, the glass fiber reinforced plastic shapes that continuously production length is not limit.This technique is most suitable for the section bar producing various section configuration, as rod, pipe, solid profile (I-shaped, flute profile, squared profile) and hollow section (door-window section bar, blade etc.) etc.
According to the surface property needs of pultrusion shape product, generally one deck surface of polyester felt need be fed at superficial layer in pultrusion process, to obtain the product surface of flat smooth.Increase mode has two kinds: one has one surface of polyester felt feeding operation, synchronous with the pultrusion speed of entirety, needs extra feeding unit; One is when producing fiberglass reinforced vegetable raw materials, just surface of polyester felt and fabric are combined, the many mode of current use is loop bonding mode, namely utilize polyester thread that fabric and surface of polyester felt are woven into an entirety, shortcoming is that product surface can show loop bonding line significantly, affects outward appearance.
Utility model content
For defect of the prior art, the utility model provides a kind of drawing and extruding section bar composite felt, have employed the mode of direct combination, glass technical fabrics, surface of polyester felt unsaturated polyester resin powder are bonded together, product has very high intensity and globality, and the surface property of product excellence given by surface of polyester felt.This product directly can reduce the operation of pultrude process, for client saves cost of labor.
The utility model is achieved through the following technical solutions: a kind of drawing and extruding section bar composite felt, comprise base cloth layer, tack coat and surface of polyester carpet veneer, described base cloth layer is Woven glass cloth layer, tack coat is unsaturated polyester resin powder, take Woven glass cloth as base cloth, sprinkle unsaturated polyester resin powder as tack coat in the one side of Woven glass cloth, in a heated state again at this face compound one deck surface of polyester carpet veneer of the Woven glass cloth sprinkled with tack coat.
As preferably, to be that glass is short cut felt, glass continuous felt, glass acupuncture composite felt, glass woven roving or glass stitch bonded fabrics to described Woven glass cloth layer, and its grammes per square metre scope is 100 ~ 2000 grams/m.Be applicable to the pultrusion of various uses and different clients.
Further, the particle size range of described unsaturated polyester resin powder is 40-200 order.
Further, the grammes per square metre scope of described surface of polyester carpet veneer is 20-100 gram/m, and composition is PETG.
Pultrusion section bar composite felt of the present utility model with different types of Woven glass cloth for base cloth, the unsaturated polyester resin powder of certain mass is sprinkled in the one side of Woven glass cloth, in a heated state again at this face compound one deck surface of polyester felt of Woven glass cloth, by the thawing cementation of unsaturated polyester resin powder, Woven glass cloth and surface of polyester felt are combined into an entirety.
The advantage of this product is the mode that have employed direct combination, and glass technical fabrics, surface of polyester felt unsaturated polyester resin powder are bonded together, product has very high intensity and globality, and the surface property of product excellence given by surface of polyester felt.This product directly can reduce the operation of pultrude process, for client saves cost of labor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.Following examples will contribute to those skilled in the art and understand the utility model further, but not limit the utility model in any form.
As shown in Figure 1, a kind of drawing and extruding section bar composite felt, comprise base cloth layer 1, tack coat 2 and surface of polyester carpet veneer 3, described base cloth layer is Woven glass cloth layer, and tack coat is unsaturated polyester resin powder, take Woven glass cloth as base cloth, unsaturated polyester resin powder is sprinkled as tack coat, in a heated state again at this face compound one deck surface of polyester carpet veneer of the Woven glass cloth sprinkled with tack coat in the one side of Woven glass cloth.The wherein total grammes per square metre of drawing and extruding section bar composite felt: 668 grams/m; Base cloth layer: grammes per square metre 613 grams/m, scrim material knittingly shortly cuts felt, belongs to a kind of glass stitch bonded fabrics; Tack coat: grammes per square metre 10 grams/m, the granularity of unsaturated polyester resin powder used is 40 orders; Surface of polyester carpet veneer: grammes per square metre 45 grams/m.The advantage of this product is the mode that have employed direct combination, and glass technical fabrics, surface of polyester felt unsaturated polyester resin powder are bonded together, product has very high intensity and globality, and the surface property of product excellence given by surface of polyester felt.This product directly can reduce the operation of pultrude process, for client saves cost of labor.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
