Abstract

The invention relates to a composite board, specifically to a sandwich-structured composite board with joint pins. A plate-shaped core material is arranged and is coated by a glass fiber reinforced plastic face plate. The composite board is characterized in that array connecting holes are drilled in the surface of the plate-shaped core material, the space between the connecting holes is 10 to 50 mm, the diameter of the connecting holes is 3 to 30 mm, the depth of the connecting holes is no more than 1/2 of the thickness of the core material, the connecting holes are equipped with joint pins prepared from resin through pouring, and the cross section of each joint pin is generally round or may be square. The processing technology for the composite board comprises the following steps: manufacturing the core material as needed; drilling the array connecting holes in the surface of the core material; and pasting the glass fiber reinforced plastics face plate on the surface of the core material. According to the invention, the contact area between the resin and the core material is increased and the adhesion force of the resin on the core material is enhanced, so the core material is tightly clamped by the face plate, thereby enhancing strength between the face plate and the core material; in addition, vertical connecting troughs and horizontal connecting troughs can promote flowing of the resin on a plane, thereby ensuring that the resin fully infiltrates a fiber. The composite board has the advantages of simple structure, convenience in operation, simplicity in construction and the like.

Description

A kind of sandwich composite board and processing technology thereof with joint pin

Technical field

The present invention relates to a kind of composite, specifically sandwich composite board and the processing technology thereof with joint pin of high, the good rigidity of a kind of intensity.

Background technology

As everyone knows, glass-reinforced plastic boat is owing to saving timber and steel, the advantage such as easy to maintenance is applied widely, on glass-reinforced plastic boat, use a lot of composite boards, as floor, boat deck, bilge plate etc., in recent years, the composite board of sandwich form is due to its good looking appearance, the reasons such as low price, utilization at building and decoration industry is more and more extensive, application on the composite board boats and ships of sandwich form is also more and more, the composite board of sandwich form is in face glass, to be provided with foamed plastic, the cores such as weedtree composite plate, its processing technology is generally to make core, paste resin bed on core surface again, then lay fiber cloth at resin layer surface, on fiber cloth cover, paste resin bed again, lay fiber cloth at resin layer surface again, on fiber cloth cover, paste resin bed again, to reaching required plate thickness, it but exists the intensity of panel and core interlayer and stiffness to reduce.

Summary of the invention

The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of sandwich composite board and processing technology thereof with joint pin that makes panel and the sandwich that core interlayer connection area increases, bonding strength is high, rigidity is good is provided.

The present invention can reach by following measure:

A kind of sandwich composite board with joint pin, be provided with tabular core, tabular core is wrapped up by glass reinforced plastic panel, it is characterized in that core surface is drilled with array-like connecting hole, the spacing of connecting hole is 10 ~ 50mm, the aperture of connecting hole is 3 ~ 30mm, and the degree of depth of connecting hole is no more than 1/2 of core thickness, and connecting hole is provided with the joint pin by resin-cast.

The section of connecting hole of the present invention is generally rounded, also can adopt square, to facilitate processing.

A processing technology for sandwich composite board with joint pin, is characterized in that step is as follows:

Step 1, make core as required,

Step 2, be drilled with array-like connecting hole on core surface, the spacing of connecting hole is 10 ~ 50mm, and the aperture of connecting hole is 3 ~ 30mm, and the degree of depth of connecting hole is no more than 1/2 of core thickness,

Step 3, paste glass reinforced plastic panel on core surface, first fill resin at core surface painting one deck resin and in by connecting hole, then lay fiber cloth at resin layer surface, on fiber cloth cover, paste resin bed again, resin layer surface re-lays fiber cloth, on fiber cloth cover, paste resin bed again, to reaching required plate thickness.

The present invention has increased the contact area of resin and core, strengthen the adhesive force of resin on core, core is tightly clamped by panel, thereby improve intensity between panel and core, and vertical link slot and horizontal link slot can also promote resin in the plane flow, guarantee that resin fully infiltrates fiber, there is simple in structure, easy to operate, the advantage such as easy of constructing.

Accompanying drawing explanation

Fig. 1 is a kind of structural representation of the present invention.

Fig. 2 is the top view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

As shown in the figure, with a sandwich composite board for joint pin, be provided with tabular core 1, tabular core 1 is wrapped up by glass reinforced plastic panel 2, Yoghourt is bright is characterised in that core 1 surface is drilled with array-like connecting hole, the spacing of connecting hole is 10 ~ 50mm, and the aperture of connecting hole is 3 ~ 30mm, and the degree of depth of connecting hole is no more than 1/2 of core thickness, connecting hole is provided with the joint pin by resin-cast, the section of described connecting hole is generally rounded, also can adopt square, to facilitate processing.

A processing technology for sandwich composite board with joint pin, is characterized in that step is as follows:

Step 1, make core as required,

Step 2, be drilled with array-like connecting hole on core surface, the spacing of connecting hole is 10 ~ 50mm, and the aperture of connecting hole is 3 ~ 30mm, and the degree of depth of connecting hole is no more than 1/2 of core thickness,

Step 3, paste glass reinforced plastic panel on core surface, first fill resin at core surface painting one deck resin and in by connecting hole, then lay fiber cloth at resin layer surface, on fiber cloth cover, paste resin bed again, resin layer surface re-lays fiber cloth, on fiber cloth cover, paste resin bed again, to reaching required plate thickness.

The present invention has increased the contact area of resin and core, strengthen the adhesive force of resin on core, core is tightly clamped by panel, thereby improve intensity between panel and core, and vertical link slot and horizontal link slot can also promote resin in the plane flow, guarantee that resin fully infiltrates fiber, there is simple in structure, easy to operate, the advantage such as easy of constructing.
