Abstract

The utility model relates to a lightweight multilayer compound board strengthened by synthetic fibre net, which is characterized in that a surface layer of the lightweight multilayer compound board is made of polymerization daub of pulverized coal ash and is strengthened by high strength synthetic fibre; a sandwich layer of the lightweight multilayer compound board is filled and pressed by lightweight particles of foam plastic in various different industry and life waste material. The lightweight multilayer compound board has thermal insulation and sound insulation properties like common architectural lightweight material, and the toughness of the lightweight multilayer compound board is strengthened, so the utility model has the advantages of light weight, energy saving property, convenient transportation and construction. The raw material of the lightweight multilayer compound board is mainly the waste material which can be obtain locally, so the transportation burden is released; the lightweight multilayer compound board has positive effect on improving and protecting environment.

Description

Lightweight multilayer compound board strengthened by synthetic fibre net

The utility model relates to a kind of laminated composite building thistle board, and particularly a kind of with the plastic wire enhancing, the light material that can make full use of in industrial waste and the household garbage is the building light-weight plate of raw material.

Existing building light-weight plate such as cement expanded perlite or gas concrete need be primary raw material with a large amount of cement, expanded perlite, have increased energy consumption and transportation burden; All not ideal enough in indexs such as aspect of performance density, intensity and coefficient of thermal conductivity, particularly breakage rate is very high in transportation.Circulate a notice of 84.2 phase E04C-01SU874923 according to patent documentation, 8402400 " moulding of laminated polymer concrete surface layer " and 84.2 phase E04C-01/40DE3144370, the plastics products for building of 8402443 " building blocks of polystyrene foam core " report, in interlayer or building block core, fill with light material, but in order to keep material that certain intensity is arranged, surface layer is compelled to do thicklyer, even also put reinforcing bar, and so not only increased deadweight, also influenced other various physical properties.On the other hand, in industrial production and people life, produce a large amount of waste materials and rubbish constantly, as flyash with remain people with the bubble wrap of crossing etc. and go to remove and utilize, become environmental protection problem suddenly to be solved.

The purpose of this utility model is to provide a kind of plastic wire to strengthen laminated composite light-weight scutum; it not only has suitable transportation of higher intensity and construction; and can extensively utilize industrial waste and household garbage to be raw material fully, and reduce production costs, help environmental protection.

The technical scheme that realizes above-mentioned task and propose is: this laminated composite plate is made up of wood property different surface layer and sandwich layer, surface layer adopts the high strength synthetic fibre net to strengthen, by polyvinyl acetate or the inclined to one side vac emulsion of chlorine, former ash is mixed 300～No. 400 polymeric clays of the cement modulation of fine-ground fly-ash and is made, its thickness is in 8～15 millimeter, length and width and shape are then pressed architectural design and construction requirement and are decided, and also can make prefabricated units; Sandwich layer is for being that diameter that the molded foamed polystyrene of cementing agent or direct heat, foam polyurethane leftover pieces, packing waste material or other lightweight waste material fragmentation form is that 5～10 millimeters particle is formed with polymeric gel mud, and the thickness of sandwich layer is 30～90 millimeters.The utility model has good physical property (seeing Table), except that have the sound insulation of common buildings thistle board, heat insulation, from the advantage of heavy and light, because surface layer has adopted and has had high-intensity polymeric clay and plastic wire and strengthen toughness and the rigidity that has improved plate, thereby this light plate cracky not in transportation and work progress; Because the facing surface strength-enhanced is durable in use especially as interlayer, partition wall; Owing to when producing this thistle board, can make prefabricated units; more can be fit to modern fabricated rapid construction requirement; another outstanding feature is that a large amount of discarded objects of industry and life are handled and utilized; gather materials on the spot and reduce the transportation and the consumption of raw material; reduce production costs; improve environmental protection, have certain economic value and social benefit.

Be described in detail by the structure of manufacturing it of the present utility model below in conjunction with accompanying drawing.

Accompanying drawing is the laminated sectional view of the utility model thistle board.

Modern is that 10 millimeters, core layer thickness are 50 millimeters with surface thickness, and its gross thickness is that the utility model thistle board prefabricated units of 70 millimeters are example: press thistle board shape, size, the thickness specification of being produced and make mould.Adopt the fleece of weaving into as the outer item for disposal synthetic fibers of terylene, polyamide fibre, polypropylene fibre, polyvinyl or the like with hole lattice (1), its warp-wise and broadwise can be also can be also different because of the fiber that stressed different mining is used with a kind of fiber by stressed directed design.Fleece (1) is cut into same specification size of the thistle board that will produce and shape, and four limits of net are fixed on the mould frame, highly are half i.e. 5 millimeters and tension of surface thickness.With polyvinyl acetate or the inclined to one side vac emulsion of chlorine, 300～No. 400 polymeric clays that former ash is mixed the cement modulation of fine-ground fly-ash pour in the mould, its thickness be 10 millimeters surface layer (2).Foamed polystyrene, foam polyurethane waste material or other lightweight waste material are crushed to the light granules that diameter is the 5-10 millimeter.In order to make full use of waste material, these light granules can be the mixtures of various waste material particles.Be layered on the surface layer (2) after light granules mixed and stirred with a small amount of polymeric gel mud, become thickness and be 50 millimeters sandwich layer (3), on sandwich layer again with the aforementioned method of manufacturing surface layer (2).Multiple last layer surface layer (2) is delivered to subsequent processing demoulding after steaming pressure, oven dry or natural curing with this plate embryo that makes together with model and is promptly made the utility model product.
