Abstract

The utility model relates to a high-strength composite board. The utility model has the basic structure that a metallic framework and glass fibre cloth are solidified together by nonsaturable resins; packing layers, such as talcum powder, quartz powder (sand), ballast, etc., which are solidified by the nonsaturable resins are added in a thickening structure. Compared with the existing metal, bamboo, wood, plastics, resin and composite boards, the utility model has the advantages of high strength, wear resistance, stability, fire retardancy, no electric conductivity, moderate weight, etc. The utility model has wide application in building industry, mining industry, manufacturing industry, etc.

Description

A kind of high-strength compound plate

The utility model relates to compound laminated plate material of a kind of high strength or plate, particularly is suitable for template for buildings, high-strength door-plate, the gripper shoe that engineerings such as mine are used, and mould is with high-strength composite plates such as plates.

In the existing sheet material or plate of above-mentioned application, on the one hand be intensity height but the metal sheet of heavy, easy-to-rust or high price, conduction; Be non-metal boards such as strength deficiency, not corrosion-resistant or easily aging wooden, bamboo matter, plastics, glass fiber reinforced plastic, resin on the other hand, also have in addition part nonmetal with metal or several nonmetal composite plate that is composited, but also have such or such deficiency.As Chinese utility model patent 94227478 " concrete pouring composite shuttering ", its die face plate is exactly by steel mesh reinforcement and is cast in the magnesium chloride on the steel mesh reinforcement, the composite material that quartz sand is formed.Because adopting magnesium chloride is adhesive material, this kind composite shuttering exists fatiguability, aging problem.

The purpose of this utility model provides a kind of high-strength composite board of novel practical, just provides composite board or the plate mainly be made up of metallic framework, resin and glass fiber specifically.

Basic structure of the present utility model contains metallic framework, glass fabric, and the cured resin layer that is solidified togather with metallic framework, glass fabric; In structure thicker, also have and resin solidification packed layer together.

Used resin can be unsaturated-resin, contains curing compound in the cured resin.These raw materials all are well known to those skilled in the art and commodity are arranged.

Packed layer also can contain fillers such as French chalk, quartz powder (or sand), rock ballast except that above-mentioned resin and curing compound.

Accompanying drawing 1 is the basic structure part sectioned view of high-strength composite board described in the utility model.

Accompanying drawing 2 is a structure thicker part sectioned view of the present utility model.

Accompanying drawing 3 is the construction formwork part sectioned view of strip edge frame of the present utility model.

Be described further below in conjunction with accompanying drawing:

In basic structure, the position is reinforced frame or net 1 under centre or the center deviation, and wherein reinforcing bar can To be screw-thread steel for building, cold-drawn steel bar (silk) or flat steel bar, become skeleton after the splicing; For slim knot Structure also can be the steel wire of different size. Can there be steel band (bar) frame the composite plate edge, also Can not be with frame. Be cured resin layer 3 around the metallic framework, it consists of 191,196,197,307 Unsaturated-resin and curing agent etc. one of model. Composite plate is to be no less than one near upper and lower surface The middle alkali glass cloth 2 of layer, and flood the unsaturated-resin (containing curing agent) of one of above-mentioned model, namely many Also be full of cured resin layer 3 between the layer glass fabric. For structure thicker, around metallic framework, increase Add packed layer 4, its composition is unsaturated-resin, curing agent, talcum powder, silica flour (sand), rock ballast etc. 2, 3,4 layers unsaturated-resin is generally identical, also can be different. The dimensions of composite plate can be carried as required Confession, thickness are generally between 5～100mm, and book size is generally between 0.5～3 square metre. Except flat Outside the panel, go back the Special-shaped Plates such as cambered surface, knuckle. The surface of plate can be with concavo-convex decorative pattern, pattern. Plate The surface can be very smooth, and roughness can reach R_m0.4 more than. Flame-retardant layer also can be with in the plate surface, or is solidifying Add fire retardant in the resin bed.

Embodiment 1 (accompanying drawing 1):

Composite plate respectively has alkali glass cloth 2 in 2 layers near upper and lower surface, and all floods 191 unsaturated-resins (containing curing compound, fire retardant); The centre is a cold-drawn bar net 1, and is immersed in the unsaturated-resin (containing curing compound) 3 that has solidified.

Embodiment 2 (accompanying drawing 2):

The composite plate centre is that welding screw-thread steel skeleton 1 reaches the packed layer of being made up of 196 unsaturated-resins, curing compound, French chalk, quartz sand, green stone quarrel 4.All the other structures are with embodiment 1.

Embodiment 3 (accompanying drawing 3):

Composite plate is a construction formwork, and the metallic framework 1 in the plate is flat steel bar welding structure, and strip has frame.All the other are with embodiment 2.

The utility model is strong with adhesion stress, stablize wear-resisting resin and tough metallic framework, glass fiber is solidified togather, and has the outstanding advantage of high strength, high abrasion, high stability, simultaneously, and, good insulation preformance in light weight, inexpensive, corrosion-resistant than metal sheet; Firm, fire-retardant than bamboo and wood, plastic plate; The composite plate that contains materials such as magnesium chloride is ageing-resistant, the life-span is long.With the test of CSS-120 electronic universal tester, the modulus of elasticity of this high-strength compound plate reaches 7400N/mm through Tsing-Hua University intensity experiment chamber ²More than, much larger than metals such as steel.And this composite plate manufacturing process is easy, and description is various.Therefore, be with a wide range of applications in fields such as building, engineering construction, manufacturing industry, and obtained practical application at present.
