Description

With reed and reed rod is precast plate primary raw material, that be used for builing industry and other industry and preparation method thereof for broken section

It is preparation method primary raw material, that be used for the precast plate of builing industry and other industry for broken section that this invention has been illustrated with reed and reed rod.

Precast plate can be the plate that is composited, and also can be made by a certain laminate that can use, form precast plate separately.How precast plate is as the structural slab in the builing industry, the self-supporting plate, it both can be used for inner surface dividing plate even decorative panel, can be used for external surface again, so can be used on the different parts of building, also can be used for making compartment or furnishings, package packing supplies and other members or the like.

The using method of reed is well-known, promptly reed is weaved into the reed mat that can adhere to the plaster coating, perhaps become reed rod single row or multiple rows to compile and string together use with iron wire or other article, yet the material of making so but can't reach uniformity consistency, do not possess the required enough intensity of multiple function again, and compile reed mat or compile the string reed rod and both needed certain technology, needing expensive special tool again, handling and loading is also pretty troublesome.Just because of this, even to this day, reed still can not replacing wood, even lack timber and the area that abounds with reed also is like this at some.

The purpose of this invention is to abandon above-mentioned all drawbacks just, earlier reed rod is bondd side by side with synthetic resin or other materials, then the different reed of hardness bits and chippy bar stem are bondd and make composite material, or make and have the precast plate synthetic wood structure, that can use separately.The plate of making like this is not only light but also have enough intensity, and also has the self-supporting characteristic, can be used for building construction, interior decoration, also can be used to build compartment, air conditioning room, noise barrier panel, thermal insulation slab and shockproof wallboard.Because this material is anti-to expand, counter-bending, tensile property is good, so multiple use is arranged when building no-reinforcing-bar, unsupported room, can make the wall of wall, balcony, floor, dividing plate and band overburden or other decorative layers, even can be used for the ship manufacturing.

The characteristics of this preparation method are precast plate compression moldings under vacuum condition.Precast plate is combined by every layer of three ply board that all can use separately: first series of strata are arranged in parallel by reed rod one end of having shelled leaf with suffering an end, are connected to each other afterwards to form; Second series of strata are made by asphalt paper or the bitumeniferous compound of one deck or similar material, and this one deck had both had sealing performance, was again one deck context layer, and radiation can also keep the sun off; The 3rd series of strata by the section bits of hard reed and tender reed or chippy bar stem with synthetic resin or other materials is bonding forms.

The accompanying drawing of this paper be the invention process method a kind of it just as example, but the invention is not restricted to this.

Fig. 1 is given in the cross section of member.

Fig. 2 and Fig. 3 are the positive and negative of precast plate.

Fig. 4 and Fig. 5 have illustrated the forming process of broken reed layer.

Fig. 6, Fig. 7 and Fig. 8 have indicated the forming process with the reed rod precast plate of parallel placement of simple overlay method or random parallel placement.

As Fig. 1, shown in Figure 4, one deck of precast plate adopts the hot adhesion method to make by the different reed section bits of broken in advance hardness.

The second layer 2 is very thin, makes with bitumeniferous compound, and be sealant, be again context layer.

The 3rd layer, 6,7, form with synthetic resin adhesive by one or more layers reed that is arranged in parallel or bar stem.

Plate 1 carried out such as beater grinder by using that the reed bits of processing make.Its interface can guarantee when bonding and between the metope firm adhesion strength is arranged.Firmly, the ratio followed of the particle pulverized of soft reed is such, one of them proportion is that 50～80% the then another kind of proportion of words is 50～20%.Each cubic metre goods approximately need 150 kilograms of viscose glues or synthetic resin.Used cementing agent can be that melamine-urea-formaldehyde or other have the compound of protection against the tide, heat resistance or ageing resistace.

This one deck can make 4,5 two faces of precast plate (Fig. 1,2,4) especially smooth and clean, can paint like this, is convenient to decorate or coat topping etc.The thickness of precast plate can be selected arbitrarily, even can be made into prefabricated section 6 as shown in the figure.

This preparation method is different from composite material mull technique (Fig. 1), can be made into precast plate 6, this member can be used for making different shape and dimensions, have or the connectionless material, have or do not have partition wall of big metal of intensity or hard material framework etc.

Prefabricated component 3(Fig. 1,3,6,7,8) make by denuding parallel reed rod of putting leaf or external particle, and with polyurethanes or polyester synthetic resin is bonding forms.Available swing roller carries out purified treatment to reed rod.

Can only make one deck or make several layers as for stacking form,, shown in the 10th layer, can also make crossbeam 12 even as among the 7th among Fig. 6, the 8th layer or Fig. 7 the 9th layer.

Precast plate (Fig. 1) is made with die pressing.In this case, need impregnated reed 3 in the adhesive groove is put in the mould.Because mechanical strength is big, this one deck both can be used as decorative cover, can reach sound insulation, effect of heat insulation again, also can shield.

The second layer 2 is films of one deck waterproof, vapor-proof.Because the cause of pitch itself, this one deck can be improved the connection degree of the reed bits of reed rod and first floor.The second layer can also and variously degrade the overcoat effect to solar irradiation.When preformed layer 1 and 3 was carried out mold pressing, the second layer can also play a part to connect the 1st and the 3rd layer except playing the interlayer effect.

The required thickness of composite material prefabricated component depends primarily on the 1st layer.This one deck is to the inertia modulus of revising prefabricated component and improve its sound insulation heat-insulating property and all play an important role.

For anti-air enters prefabricated component, preferably mould is placed under the effect of vacuum during making, thereby improve the performance of precast plate, whole uniformity and anti-breaking strength (this fracture is to cause owing to bubble that material and bonding agent inside have).

In bonding agent, can add the various protective agents that prevent chemical attack, mechanical wear and solar irradiation and catch fire and prevent insect and parasite infringement.Before using, can handle again used various materials.

So because this material weight is light, intensity is big, the hard durable range of application is extremely wide, aspect builing industry, can be used for critical piece in building frame, the building, also can be used as dividing plate, floor, overburden or the like.

Fig. 1,2,3 or Fig. 4,5,6,7 shown in its inside and outside surface of precast plate aspect process application and the decorative applications aspect all useful.Precast plate shown in Fig. 3,5,6 can be used to do the roof to replace cogongrass.

Layer 1, layer 2 layer 3 even all can be made respectively, and can distinguish as required separately and use.Every layer can bond together them as shown in Figure 1 after the making respectively, avoid the employing die pressing to make whole assembly.

Therefore shape, size and the method for arranging of various members as long as can change to some extent, but can't change the general design thought of the invention described above like this in equivalent scope.
